Background: Medial fasciocutaneous flaps, which are based on the femoral artery from the thigh region, are used for wide inguinal, scrotal, vaginal, perineal, leg, head and neck defect reconstructions in injured human patients. Within this regard, anatomical knowledge about perforating and cutaneous branches of the femoral artery is important for the surgeons. Materials and methods: In the present study, vascular pedicles of the medial thigh perforator flap based on the femoral artery were investigated according to anatomical and surgical landmarks. Human Caucasian preserved cadavers of 15 adults (13 males, 2 females; age range 55–82 years: 30 sides, bilaterally) that were previously formalin fixed were subjected to our analytical examinations. Micro dissections were performed under 4× loop magnification while representing the perforating branches of the femoral artery after filling by coloured latex injection via the external iliac artery. Results: The size and length parameters of these branches which appeared around the apex of the femoral triangle were evaluated. The mean size of the perforating branch at the point of origin was 0.14 cm and the mean size of the cutaneous branch at the point of origin was 0.09 cm, the mean length of the pedicle was 4.74 cm and the mean length of the cutaneous branch was 3.30 cm, respectively. Location of the perforating and the cutaneous branches were also determined according to the surgical landmarks such as the anterior superior iliac spine, inguinal ligament, pubic tubercle and interepicondylar line. Conclusions: The pedicle of the medial flap should locate up to 25 cm from the anterior superior iliac spine so as to preserve the vascular structures. Exact location of this artery helps the surgeons to perform anastomosis in an easier and safer manner during surgical operations. (Folia Morphol 2016; 75, 1: 27–32)

The femoral artery (FA) and its branches play important roles in the arterial supply of the lower extremity. If the femoral artery is occluded, the circulation of the extremity is maintained by certain anastomoses. Therefore, identification of variations of these arteries is critical from a clinical and surgical point of view. During routine anatomical dissections for student education at the Department of Anatomy of the School of Medicine at Ondokuz Mayls University, a variation of the medial circumflex femoral artery (MCFA) was observed and photographed in a male, formalin-fixed cadaver aged 55 years. In this case, MCFA branched off from the posterolateral aspect of the FA, 32 mm distal to the inguinal ligament. A frequency rate of 17–26% has been reported regarding this variation. However, MCFA emerging from the postero-lateral aspect of the FA and its course, as in this case, is not that frequent. Knowledge of anomalies in the emergence and course of the arteries that join the cruciate anastomosis and are important in the arterial supply of the head and neck of the femur appear to be a critical component that requires caution during surgical interventions towards this region.

During routine anatomical dissections, absence of the musculocutaneous nerve was determined in a 58-year-old male cadaver. Moreover, the biceps brachii and brachialis muscles were innervated by two separate branches which divided from the median nerve instead of the musculocutaneous nerve. From a branch that divides from the main trunk of the median nerve at nearly the middle of the arm a motor branch again divided that innervated the brachialis muscle and a sensory branch that conveyed the sense of the lateral part of the forearm. Furthermore, it was found that the brachial artery divided into its terminal branches, the radial and ulnar arteries. We believe that this rare variation of the median nerve will shed light upon surgical procedures involving the median nerve.

Background: The aim of this study was to investigate the incidence of the suprascapular foramen in West Anatolian population. Materials and methods: Eighty-one dried human scapulae of West Anatolian people of unknown ages and gender belonging to the Anatomy Department Laboratory of Dokuz Eylul University Medical School were examined macroscopically. The vertical and transverse diameters of the suprascapular foramen and central thickness of the ossified ligaments were measured with calliper in millimetres and digital calliper, respectively. Results: We observed the suprascapular foramen due to ossification of the suprascapular ligament only in 2 of 81 (2.47%) scapulae. The vertical and transverse diameters of the suprascapular foramen and central thickness of the ossified ligaments (No. 1 and No. 2) were measured as 8.0 mm vs. 4.0 mm, 3.6 mm vs. 2.0 mm and 4.0 mm vs. 1.4 mm, respectively. Conclusions: The suprascapular foramen caused by ossified suprascapular ligament is rarely observed variation in West Anatolian population. (Folia Morphol 2016; 75, 1: 21–26)
