Aim: The aim of the study is an attempt to answer the question whether a long-term karate practice exerts influence on the incidence of injuries and what its type and underlying cause. Methods: The research was carried out in July 2013 in Cracow during a karate training camp. 125 people from Poland participated in the study. The participation in research was voluntary and people were informed about its aim and application. The average age was 37,6 ± 11,3 years. The youngest participant was 15 and the oldest 57. Median age was 39 which means that half of participants was not older than 39 and the other half was at least 39. Questionnaire techniques were used in the study. The research tool used to implement the selected technique was survey questionnaire. The questionnaire consisted of 23 open- and close-ended questions. Results: As results from own research, the greatest number of competitors (38) have suffered from contusion (47,1% of all injury types). This injury types constitutes almost half of all injuries. Among all injury types karate contestants suffered from last year, the most common were contusions (25,6% of all injuries). Conclusions: Karate training is not related to any serious injuries apart from contusions which at the same time are most common injury in this type of training. Contestants’ and training experience are not directly related to injury incidence. An appropriately organized, rational training and using prevention enables to avoid injuries. Circumstances of injury incidence change with contestants’ age and training experience.

EN
Recreational running is an activity with multiple reported health benefits for both sexes, however, chronic injuries caused by excessive and/or repetitive loading of the Achilles tendon are common. Males have been identified as being at an increased risk of suffering an injury to the Achilles tendon and as such, knowledge of differences in loading between the sexes may provide further information to better understand why this is the case. The aim of the current investigation was to determine whether gender differences in the Achilles tendon load exist in recreational runners. Fifteen male (age 26.74 ± 5.52 years, body height 1.80 ± 0.11 m and body mass 74.22 ± 7.27 kg) and fifteen female (age 25.13 ± 6.39 years, body height 1.68 ± 0.12 m and body mass 67.12 ± 9.11 kg) recreational runners volunteered to take part in the current investigation. Participants completed 10 trials running at 4.0 m·s-1 ±5% striking a force platform (1000 Hz) with their right foot. Ankle joint kinematics were synchronously recorded (250 Hz) using an optoelectric motion capture system. Ankle joint kinetics were computed using Newton-Euler inverse-dynamics. Net external ankle joint moments were then calculated. To estimate Achilles tendon kinetics the plantarflexion moment calculated was divided by an estimated Achilles tendon moment arm of 0.05 m. Differences in Achilles tendon kinetics were examined using independent sample t-tests (p<0.05). The results indicate that males were associated with significantly (p<0.05) greater Achilles tendon loads than females. The findings from this study support the notion that male recreational runners may be at greater risk of Achilles tendon pathology.

Introduction The foot is an important element of the human motor system. It is a single mechanism of propulsion and amortisation. Sports people, football players in particular, are especially prone to limb loading. In this discipline, the first contact with the sport as well as training begin at a very young age. In order to prevent traumas and injuries among young players, it is important to assess their foot arch. Material and methods A group of 30 players aged 13-18 who played football at the Progres Sports Academy in Cracow and at the lower- and upper-secondary schools in Cracow under the patronage of Marcin Gortat were tested. The tests involved the podoscopic evaluation of both feet, the test of both feet on a tensometric mat and a survey. To assess the longitudinal foot arch, Clarke’s angle was applied in the authors’ own tests. The transverse arch was evaluated using the Wejsflog index. Results For the overwhelming majority of the persons tested, the most common type of longitudinal arch was flat foot. Only a scant minority had a tendency towards hollow foot. The most common injuries among the examined footballers included muscle pulling and tearing as well as sprains and overloading. Most players suffered injuries of thigh muscles, knee joints, tarsal joints and feet. Conclusions It was confirmed that there was a significant correlation between the intensity of training and the frequency of injuries.

Objectives: The aim of the study was to assess the function of semicircular canal in videonystagmography head impulse test (VHIT) in the patients with vertigo and balance disorders. Material and Methods: The study was performed in 135 patients (86 women and 49 men) aged 22–79 years, who were divided into 2 groups: I (study group) – 73 patients with vertigo of peripheral, central or mixed origin, II (control group) – 62 patients without vertigo (healthy individuals). The function of canal was determined on the basis of GAIN and expressed as DG/RH×100% (where DG is deviation of gaze and RH is rotation of head). Results: In the study group the semicircular canal injuries were found in 37 (50.69%) patients, including 24 (32.87%) patients with 1 injury and 13 (17.8%) patients with 2 or more injuries in semicircular canal. The injured anterior semicircular canal was reported 13 times; the lateral – 9 times and the posterior – 31 times. Conclusions: In the study group, in the VHIT, injuries in semicircular canals were reported in peripheral vertigo, mixed vertigo with non-compensated and compensated function of the labyrinth in 50.68% cases, whereas in the caloric test dysfunction of the labyrinth was found in 58.49% cases.

Background The profession of a firefighter involves multiple factors that directly or indirectly impact on the person's health. The aim of this study was to establish the correlation between physical fitness of the selected group of firefighters with respect to anthropometric parameters, additional physical activity, and injury rate. Material and methods The study examined 77 men who worked for the State Fire Service (age: 28.87±9.84 years, body mass: 82.13±9.37 kg, body height: 180.12±6.39 cm). Of he study group, 53% of the fire-fighters had normal BMI, 42% were overweight and 5% had first degree obesity. The study used a survey questionnaire concerning the anthropometric data, previous injuries, physiotherapeutic procedures following the injury, and participants' involvement in additional physical activity. A physical fitness test battery was used to determine the correlation between physical fitness and: age, BMI and additional physical activity and injury rate. Results Musculoskeletal injuries accounted for 51% of all injuries. Of all injuries, 56% were occupational. The correlations between the results of the handgrip test were insignificant with respect to BMI and age, whereas in other tests, the correlations were statistically significant (p<0.05). No differences were observed in the results of handgrip test between the group of firefighters who were and those who were not involve in additional physical activity. Comparison of the results obtained by firefighters following the injury and without previous injuries revealed a statistically significant difference (p<0.05) in the 4 x 10 m shuttle run. Conclusions Age and higher values of BMI are the factors that reduce the level of physical fitness of firefighters. Involvement in additional physical activity is a factor in improving physical fitness of firefighters. Previous injuries the firefighters had suffered did not have an effect on their physical fitness.

INTRODUCTION: Road accidents lead to injuries which are one of the most common causes of hospitalisation in trauma centres. Proper placement and number of EMS units determine quick arrival in the scene of accident and need for transport to the adequate healthcare entity. MATERIAL AND METHODS: An analysis was carried out of the profile of the patient, the distance to the scene of accident as well as the allocation of accident casualties to healthcare entities. A statistical analysis was conducted by means of the Chi-Square Test of Independence and the Kruskal–Wallis test by ranks. RESULTS: Distances between the scenes of accidents and places where EMS units were stationed was from 0.5 to 37 kilometres (mean: 9.8 km). 170 patients participated in the accidents. Most frequently, these were males at the age from 21 to 40 (mean: 35.77 ± 15.45). The most common diagnoses according to ICD-10 were injuries to the head (42.7%) and injuries of lower limbs (12%). In most cases, the accident casualties were transported to the Emergency Department in Łuków. 21 patients in total were placed in hospital facilities outside the catchment area. The Polish Medical Air Rescue transported the 10 patients in the most severe condition. CONCLUSIONS:Road accidents are most frequently experienced by middle-aged men. Injuries to the head and of lower limbs are the most common injuries. The placement of EMS units in the area under analysis is optimal, but the mean distance covered by the ambulance to reach to scene of accident is nearly 10 kilometres. Despite the presence of the Emergency Department in Łuków, one in ten injured patient warrants transport outside the catchment area and almost 6% of patients qualify for transport by air.

WSTĘP: Wypadki drogowe powodują obrażenia, które stanowią jedną z najczęstszych przyczyn hospitalizacji w centrach urazowych. Prawidłowe rozlokowanie i liczba zespołów ratownictwa medycznego (ZRM) decyduje o szybkim dotarciu do miejsca zdarzenia, a także potrzebie transportu do właściwego podmiotu leczniczego. MATERIAŁ I METODY: Analizie poddano profil pacjenta, odległości do miejsca zdarzenia, a także alokację poszkodowanych do podmiotów leczniczych. Do opracowania statystycznego wykorzystano testy niezależności Chi kwadrat oraz Test Kruskalla-Wallisa. WYNIKI: Odległości do wypadków od miejsc wyczekiwania ZRM wynosiły od 0.5 do 37 kilometrów (średnia 9.8 km). W wypadkach brało udział 170 pacjentów, najczęściej byli nimi mężczyźni w wieku od 21 do 40 lat (średnia 35.77 ± 15.45). Najczęstszymi rozpoznaniami według ICD-10 były urazy głowy (42.7%) i kończyn dolnych (12%). W większości przypadków, miejscem transportu poszkodowanych był SOR w Łukowie. Do jednostek szpitalnych, poza rejonem operacyjnym skierowano łącznie 21 osób. Lotnicze Pogotowie Ratunkowe przetransportowało 10 pacjentów w najcięższym stanie. WNIOSKI: Zdarzeniom drogowym ulegają najczęściej mężczyźni w średnim wieku. Dominują obrażenia głowy i kończyn dolnych. Rozlokowanie ZRM w badanym rejonie jest optymalne, lecz średni dystans karetki do miejsca zdarzenia wynosi prawie 10 kilometów. Pomimo istnienia SOR w Łukowie, co dziesiąty ranny wymaga transportu poza rejon operacyjny, a prawie 6% pacjentów kwalifikuje się do transportu lotniczego.

Introduction Basketball is characterized by high intensity play and a lot of physical contact. Players are required to be well-trained physically in order to be able to face the dynamics, speed and variability of the game and the training loads to which they are exposed. Basketball is a sport that predisposes the athletes to musculoskeletal injuries. The aim of this study was to characterize the injuries experienced by young adult male basketball players. Material and methods Young adult male Polish basketball players from various clubs (17±1.4 years; n = 28; 47%) and amateur basketball players (17±1.4 years; n =30; 53%) took part in this study. To assess the injuries of young basketball players, a survey consisting of 28 questions was used. Results The most common injuries were lower limb injuries (54%), of which ankle injuries prevailed (ankle injuries were the most common injuries of all). Upper limb injuries accounted for 36% of all injuries. Of these, subluxations in finger joints occurred most often. Most often, injuries occurred during physical contact with another player (40%). Despite an injury, the players either did not alter the length of their warm-up or they devoted more time to it. In terms of stretching before a training session or a match, differences between players training up to three times a week and players training four or more times per week were statistically significant (χ2 = 8.926, p = 0.012, V = 0.392). Conclusions Basketball is a sport that causes injuries. Basketball players mostly experience lower limb injuries.

Burns represent a significant percentage of injuries amongst trauma patients. The risks from a burn wound depends on the causative factor, time and place of exposure, extent and severity of the burn. Classification according to the American Burn Association indicates that severe burns should be diagnosed from as low as 10% of Third-degree total body surface burn. The burn disease develops progressively through shock, catabolic and anabolic phases until the development of Multiple Organ Dysfunction Syndrome (MODS). Actions performed in the pre-hospital phase are crucial for the effectiveness of the therapeutic process. Wrongful first aid performed by a witnesses of the event may worsen the patient's condition and lead to secondary infection. Studies available in the literature indicate the use of egg whites, yoghurts and ice as means of first aid. Educational projects to promote good practice, using products such as hydrogel dressings, seem therefore necessary. Medical personnel should quickly assess the extent and severity of burns. Furthermore, one ought to implement volume-calculated fluid therapy, protect the respiratory tract and strive to ensure thermal comfort. It seems mandatory to assess the extent of pain and administer appropriate pharmacological measures to perform analgosedation. Due to the limited number of specialist burn treatment centres, paramedics should consider indications for hospitalization and the use of Medical Air Rescue (MAR) enabling rapid patient allocation.

Oparzenia stanowią znaczny odsetek wśród pacjentów urazowych. Zagrożenia wynikające z powstania rany oparzeniowej zależą od czynnika powodującego, czasu i miejsca ekspozycji, rozległości oraz stopnia oparzenia. Klasyfikacja według American Burn Association wskazuje, że oparzenia ciężkie należy rozpoznać już od 10% powierzchni ciała oparzonej w stopniu III. Choroba oparzeniowa rozwija się stopniowo przechodząc przez fazę wstrząsową, kataboliczną, anaboliczną, aż do rozwinięcia się pełnoobjawowego zespołu niewydolności wielonarządowej (MODS – Multiple Organ Dysfunction Syndrome). Dla skuteczności procesu terapeutycznego kluczowe są działania wykonane w fazie przedszpitalnej. Błędnie udzielona pierwsza pomoc przez świadków zdarzenia może pogorszyć stan pacjenta i prowadzić do wtórnego zakażenia. Badania dostępne w literaturze wskazują na wykorzystywanie w ramach pierwszej pomocy białek jaj kurzych, jogurtów i lodu. Dlatego konieczne wydają się projekty edukacyjne promujące prawidłowe zasady postępowania, z wykorzystaniem takich produktów jak opatrunki hydrożelowe. Personel medyczny powinien dokonać szybkiej oceny rozległości i stopnia oparzeń. Należy wdrożyć odpowiednio wyliczoną objętościowo płynoterapię, zabezpieczyć drogi oddechowe i dążyć do zachowania komfortu termicznego. Obowiązkowa wydaje się ocena skali bólu oraz podanie właściwych środków farmakologicznych w celu wykonania analgosedacji. Z uwagi na ograniczoną liczbę specjalistycznych ośrodków leczenia oparzeń ratownicy medyczni powinni rozważyć wskazania do hospitalizacji, a także wykorzystanie Medical Air Rescue (MAR) umożliwiającego szybką alokację pacjenta.

Purpose. Using databases available on the Internet, the number of scientific papers on the subject of field hockey were examined. Basic procedures. As a result, 208 scientific studies covering the fields of biochemistry, physiology, sport injuries, psychology and tactics were found, which were published within the last 50 years (from 1960 to 2010). Despite the popularity of field hockey and its status as an Olympic sport, the number of scientific studies which focused on field hockey was much smaller when compared to the amount of publications on other team sports, such as soccer, basketball, or baseball. Main findings. It was found that the greatest number of publications (61.06%) originated from five English-speaking countries (UK, USA, Canada, Australia, and New Zealand), with the majority focusing on sport psychology, injuries and biochemistry. What was discovered was that the vast majority of scientific studies used field hockey merely as a reference point in comparison to other team sports. Conclusions. The varying topic diversity of the scientific studies found among the databases significantly hinders an effective comparison of findings, especially considering that most of the studies focused on only a few selected aspects of the problem matter and were chiefly small sample studies, nor were they repeated.

Objectives This study has aimed at identifying prevalence of injury-occurrence in 24 pre-professional-ballet-dancers (females, 16–18 years of age), and identifying the associations between the body-built and prevalence of injuries. Material and Methods The sample of variables included: body mass, body height, and 3 somatotype characteristics (mesomorph, ectomorph and endomorph) and data on injuries over the preceding year. Results Dancers were mostly ectomorphic-mesomorph (endomorphy: 2.6±0.54, mesomorphy: 3.99±0.77, ectomorphy: 3.23±0.54). The most commonly injured locations were the foot (17% of all injuries) and ankle (17%). Majority of the injuries occurred while practising but 37% of hip-injuries occurred while performing. Ankle-injuries resulted in longest absence from ballet. Endomorphy was related to ankle-injury (odds ratio (OR) = 1.9, 95% confidence interval (CI): 1.4–2.3), ectomorphy to foot injury (OR = 1.7, 95% CI: 1.1–2.9), and body-mass to injury to the toes (OR = 1.7, 95% CI: 1.4–3.1). Conclusions The results of this study allow for recognizing those dancers who are particularly vulnerable to injuries of certain body location. A more profound analysis of the possible mechanisms that lead to hip-injury during performance is needed. Int J Occup Med Environ Health 2017;30(1):151–159

Street cleaning is an integral part of the solid waste management system. There are different ways to achieve clean streets depending on the availability of equipment, the type and magnitude of dirt, the surface conditions encountered or traffic conditions. In general, hand sweeping by an individual worker or a group, hose flushing, or machine sweeping or flushing are applied. In order to obtain information about the occurrence and relevance of occupational health hazards of street cleaners, the current international literature, as well as corresponding German regulations, were reviewed and evaluated. Street cleaning includes a variety of health hazards for employees. These can be subdivided into effects of occupational tasks and effects of working conditions such as weather or road traffic. The hazards result from physical, chemical and biological exposures, but may also be due to physiological and psychological burden or inadequate safety aspects. The most commonly reported work-related complaints are musculoskeletal and respiratory disorders, cuts, slips, and road traffic accidents. In developing countries, street cleaners seem to be still heavily exposed to dust and, in most cases, no suitable protective measures are available. Especially in industrialized countries there exist a number of standards and recommendations for waste workers that aim to reduce their occupational health impacts.

ObjectivesThe purpose of this study was to characterize a new respiratory syndrome associated with exposure to a humidifier disinfectant (HD) in South Korea that is distinct from the well-known HD-related lung injury (HDLI). The authors identified this condition in 24 study subjects who were family members of patients with definite or probable HDLI (referred to as index cases), and were exposed to HD in the same room as the index cases.Material and MethodsThe authors reviewed medical records of 236 family members in 110 families who were exposed to HD in the same rooms and residences as the index cases.ResultsThey identified 24 family members who were exposed to HD in the same rooms and residences as the index cases, and who developed respiratory disorders that were distinct from HDLI. The clinical signs and symptoms of these individuals were in the upper respiratory tract, such as allergic rhinitis and croup, or in the lower respiratory tract, such as bronchitis and pneumonia. The diffusing capacity of the lung fordetermicarbon monoxide was reduced in 9 of 12 children (data not available for 1 child), and in 4 of 5 adults (data not available for 6 adults). The percent forced vital capacity and forced expiratory volume in one second/forced vital capacity ratios were within the normal ranges in most patients. The computed tomography findings, which mostly indicated non-specific inflammation, were inconsistent with the radiological diagnostic criteria for HDLI, but were abnormal in 8 of 11 adults, and in 2 of 13 children.ConclusionsThe authors propose a new condition, i.e., HD-related respiratory syndrome (HDRS), which is characterized by mild to moderate or atypical respiratory symptoms and signs, and is related to HD exposure, but is distinct from HDLI. The recognition of HDRS may provide a basis for understanding the natural history of HD-related respiratory problems, and for capturing the whole spectrum of HD-related clinical manifestations in the respiratory tract.

This article is based on 2 studies. The aim of the first study was to examine the differences in occupational accident frequency between the 2 main language groups in Finland. Based on 3 independent statistical data sets, it was shown that Swedish-speaking workers had about 40% fewer occupational accidents than Finnish-speaking workers. The aim of the second study was to confirm the difference at company level. A field study in the province of Vaasa with 14 small and medium-sized manufacturing companies revealed that the accident frequency of Swedish-speaking workers was 21% lower than that of Finnish-speaking workers.

Background. The hip joint is one of the most important joints in the human body. Although its multiaxial movements account for many benefits, they also render the hip one of the most hard-working joints. Injuries to the hip joint and thigh often occur as a result of a fall. According to epidemiologic data, such falls are most frequent in the elderly, particularly in osteoporosis sufferers. Material and methods. The “Services” component of the Statistics API version 1.0 provided by the National Health Fund (NHF) was used in order to evaluate the number of hospitalizations due to hip joint and thigh injuries. Information on the number of patients was obtained in a number of stages. The first stage involved determination of hip and thigh injuries as the main diagnosis. Then, the billing products which made possible settlement for hospitalization of patients with the selected diagnoses were chosen. The last stage consisted in the extraction of relevant medical data sets from the “Services” component of the NHF Statistics API, which made possible this analysis. Results. According to the NHF reporting data, over the four-year period of interest there were approx. 42,000 hospitalizations per year. The most frequent causes of hospitalization were fractures of the neck of the femur (S72.0) and trochanteric fractures (S72.1), accounting for approx. 48% and 36% of all hospital stays, respectively. Conclusions. 1. Hip injuries constitute a significant health problem in Poland (approx. 42,000 hospitalizations per year). 2. The most frequent causes of hospitalization are injuries in the form of fractures of the neck of the femur or trochanteric fractures (corresponding to the ICD-10 codes S72.0 and S72.1, respectively). 3. It appears advisable to develop a tool to enable medical service providers to adjust their services to patients’ changing needs. This tool could employ open-access data on injuries published in the NHF Statistics API.

Wstęp. Staw biodrowy jest jednym z najważniejszych stawów ludzkiego ciała. Wieloosiowe ruchy w stawie pomimo niewątpliwych zalet sprawiają, że staw biodrowy jest prawdopodobnie jednym z najciężej pracujących stawów ludzkiego ciała. Uszkodzenie stawu biodrowego czy struktur uda często powstaje w wyniku upadku, który jak wskazują dane epidemiczne najczęściej zdarza się osobom starszym, szczególnie w przypadku osób cierpiących na osteoporozę. Materiał i metody. W celu określenia liczby pacjentów hospitalizowanych z powodu urazu stawu biodrowego i uda posłużono się Interfejsem API Statystyki NFZ – Świadczenia wersja 1.0. Proces prowadzący do uzyskania informacji dotyczącej liczby pacjentów odbył się w kilku etapach. Pierwszy etap stanowił wybór rozpoznań głównych z zakresu urazów stawu biodrowego i uda. Następnie wyłoniono produkty, w ramach których możliwe było rozliczenie hospitalizacji pacjentów z wybranymi rozpoznaniami. W ostatnim etapie wygenerowano odpowiednie zbiory danych medycznych z wykorzystaniem Interfejsu API Statystyka NFZ – Świadczenia, pozwalające na przeprowadzenie analizy. Wyniki. Zgodnie z danymi sprawozdawczymi NFZ łącznie na przestrzeni 4 analizowanych lat obserwowanych jest średnio prawie 42 tys. hospitalizacji rocznie. Najczęstszym powodem hospitalizacji były złamanie szyjki kości udowej (S72.0) i złamanie przezkrętarzowe (S72.1) stanowiące średnio ok. 48% oraz 36% wszystkich hospitalizacji. Wnioski. 1. Urazy stawu biodrowego stanowią duży problem zdrowotny w Polsce (średnio prawie 42 tys. hospitalizowanych pacjentów rocznie). 2. Najczęstszą przyczyną hospitalizacji są urazy związane ze złamaniem szyjki kości udowej oraz złamaniem przezkrętarzowym (zgodnie z ICD-10 S72.0 i S72.1). 3. Uzasadnione jest stworzenie narzędzia umożliwiającego podmiotom medycznym dostosowywanie usług do zmieniających się potrzeb pacjentów. Narzędzie to może wykorzystywać ogólnodostępne dane dotyczących urazów publikowane w API Statystyki NFZ.

This study presents possibilities to apply the numerical simulation of dynamic response for explosive (impulse) loads, caused by detonation of mine under the military armoured vehicle, acting on a crew member seating in chair, in order to determine methods to minimize the results of impact of vehicle body structure on the crew, mainly caused by it accelerations and overloads. Furthermore, this article presents factors, which have impact on numerical model and detonation phases necessary to conduct the mentioned above simulation. Information on physical values acting on the soldier and injuries resulting from such actions are important to understand how important element, improving physical protection of soldiers during mine detonation below the armoured military vehicle, is a chair. According to the dissertation "Development Of Lower Extremity Injury Criteria And Biomechanical Surrogate To Evaluate Military Vehicle Occupant Injury During An Explosive Blast Even" the most common injuries occurring during mine explosion under the military vehicles, eliminating soldiers from further service, include: sprain of vertebras, fracture of vertebra, light fracture of skull, brain shaking, brain concussion, fracture of tibia, damage to ilia, fracture of fibula bones. These injuries occur most often at the first two stages of explosion, called local and global effect.

Introduction: Common etiologies of acute traumatic peripherial nerve injury include penetrating injury, crush, stretch, and ischemia. Purpose: This paper reports an epidemiological and clinical study of patients with peripheral nerve injuries who were treated for upper limb trauma, which included nerve injury, surgically treated in the Department of Orthopedics University Hospital in Bialystok, in the years 1997-2007.Materials and methods: A total of 202 patients with injury to the median, ulnar and radial nerves were involved in the study. Based on the medical history concerning day care and inpatient hospitalization, surgery books data and the analysis of medical histories, the data referring to the nerve trauma were analyzed. Results: The data allowed a reliable assessment of the population of patients with upper limb nerve injury and methods of treatment, as well as quantitative presentation of the methods of repair and reconstruction of the damaged nerve stem. Conclusions: In the Department of Orthopedics, Medical University of Bialystok, in the years 1997-2007 delayed nerve injuries were more frequently treated than the immediate ones. Surgical treatment of nerve injuries most frequently used primary suture and cable grafting reconstructions. Secondary epineural suture of the nerve was performed more rarely. Autogenic nerve graft segments were most frequently collected from the ulnar nerve of the lower extremity. The medial antebrachial cutaneous nerve grafting was much seldom performed.

This paper presents findings from an extensive study into factors that impact upon the high rate of injuries due to mechanical equipment, especially in small manufacturing firms. Issues relating to knowledge of health and safety issues and to management practices have been shown to be extremely important with regards to safety in smaii businesses. Knowledge and awareness of hazards were found to be relatively low and few respondents, especially managers, had received adequate safety training. Managers did not regard the identification and control of risks as a priority. Workplaces generally lacked effective safety management procedures such as safety rules and regulations, procedures for recording and learning from accidents, and clearly defined responsibilities for safety. Some issues requiring further investigation, and some recommendations for improving safety in small businesses, are presented.
