Diaphyseal fractures of the femur are rather common. In the treatment of fractures of the femur various methods of osteosynthesis can be used: intramedullary, of plate, transosseus. In our country external fixation using external fixation devices has traditionally been popular. Objective. The analysis of the frequency of use of transosseous osteosynthesis in the treatment of fractures of the femur and the identification of the most common indications for the use of the method in the present practice. Materials and Methods. The analysis of the structure of external fixation in fractures of the femur, on the experience of treatment of 126 patients with diaphyseal fractures of the femur. Results. The results of the study revealed that the structure of the osteosynthesis of fractures of the femur transosseous osteosynthesis with the use of external fixation devices is not considered to be common and is used as an alternative method of treatment. Conclusion. The treatment of fractures of the femur using transosseous osteosynthesis is currently used mostly for open, comminuted fractures and revision osteosynthesis, as well as a high risk of infectious complications in the zone of fracture, due to complexity of the method, the lowest strength of fixation and a relatively high percentage of non-specific complications.

This article presents new intramedullary (IM) nail design for femur diaphyseal fractures osteosynthesis. Biomechanical comparison of the two IM nails (standard locking and new developed) was conducted. Femur medullary canal architectonics was studied with the help of computer tomography (CT) data. Three-dimensional (3D) models of the femur, its transverse fracture, standard locking nail and new developed nail were constructed as well as the bone-implant system models. Stress-strain state of the bone-implant systems under three types of loads (axial, lateral and torsional) was studied using finite-element method in commercial software Ansys 14.0. Numerical results showed that new nail allows proximal fragment of the bone to move in an axial direction. New nail provides necessary compression at fragments junction. It was revealed that the highest values of effective stress (ES) for the standard nail were concentrated at contact area between locking screws and nail for all investigated loads. For the new nail the highest values of ES were concentrated on its body and blades at proximal region. Moreover, stresses occurred in the new nail were smaller than stresses appeared in the standard nail. This conclusion is valid for three investigated types of loads. So the new nail does not have serious disadvantages of standard nails. From the biomechanical point of view the new nail is more preferable for diaphyseal femur fractures osteosynthesis.

Purpose: to reveal features of bone structures correlation of acetabulum and femoral components of a hip joint. Material and methods. The sizes of acetabulum, pelvis and proximal metaepiphysis of femur have been determined on 98 sets of pelvis and femurs and 120 KT-grams of adults. Results. Sexual and bilateral distinctions, correlation of bone structures of acetabulum, proximal metaepiphysis and femur have been revealed. Conclusion. The received values of the main morphometric parameters of bone structures of hip joint and pelvis and their correlation develop the database of clinical anatomy of hip joint.
