More than one-third of Germany’s Douglas-fir resources, stock in age-classes from twenty-one to fifty-nine years. As such timber increasingly enters markets, detailed knowledge of the anatomy and properties of its wood is of importance to forest managers and wood processors. Anatomical and mechanical wood analyses in this study were carried out on twenty trees from four scientifically managed plantations in Southern Germany. The age of the trees selected was forty-two years whereby varying growth conditions were considered. Juvenile and adult woods were identified by segmented linear regression of radial profiles of anatomical characteristics, such as latewood percentage, tracheid wall thickness microfibril angle and density. Additionally, the width of earlywood, latewood and growth rings as well as bending modulus of elasticity were determined. Variance was dependent on the trait used for differentiation, juvenile wood comprised of an eleven to thirty-one growth rings resp. radial amounts of fifteen to sixty-five percent. When compared to adult wood, juvenile wood showed corresponding features of approximately thirty percent wider growth rings, thirty four percent lower latewood percentage, fourteen percent thinner tracheid walls, and eighty percent larger microfibril angles, eleven percent lighter wood and fifty-seven percent lower bending modulus of elasticity. As the assortment features fast grown trees, adult heartwood characteristics were slightly inferior to the characteristics of European Douglas-fir.

Background: The aim of the study was to describe the innervation of flexor hallucis longus (FHL) and obtain its surgical coordinates to facilitate selective neurotomy. Materials and methods: Fifteen embalmed lower limbs of adults were studied. Anatomical dissections to isolate the innervating branches of FHL were performed. Distance between the supplying nerve of FHL, including both its origin and termination, and the medial malleolus were obtained, providing anatomical coordinates beneficial for surgery. Results: In all cases, FHL was innervated by only one branch, which originated from the tibial nerve. Mean distance between the medial malleolus and the nervous branch origin was 21.39 ± 3.05 cm. Mean distance between the medial malleolus and the nervous branch termination was 12.7 ± 1.59 cm. Length of the nervous branch innervating FHL was proportional to the length of the leg, measuring 8.69 ± 2.45 cm. All nerves were located 15–17.4 cm above the medial malleolus. Conclusions: This anatomical study traced valuable surgical coordinates useful for performing selective peripheral neurotomy on the nerve branch innervating the FHL.
