Objective - to improve treatment outcomes in patients with medial fractures of the femoral neck through the development and introduction into clinical practice a new method of fixation with non-free plastic by the autograft from the iliac crest on a permanent muscular-vascular pedicle. Materials and methods. A comparative analysis of short- and long-term results of surgical treatment of 57 patients with medial fractures of the femoral neck, which were divided into primary and control groups. The study group included 24 patients who have undergone an osteosynthesis with cannulated screws with additional autoplasty with vascularized graft from the iliac crest. The control group consisted of 33 patients who underwent fixation with cannulated screws for the traditional method. Results. The use of non-free bone autoplasty in the main group of patients provided the best short- and long-term outcomes: fracture healing occurred in all cases in a period of 6 to 8 months. The long-term results of treatment of 22 patients after 2-6 years after the operation showed comparatively better anatomical functional outcomes. Conclusions. The indications for the clinical use of the fixation with the non-free bone autotransplantation are prognostically unfavorable for the union medial fractures of the femoral neck (II-III types by Pauwels or III-IV types by Garden) in patients aged under 60 years with no signs of deforming arthrosis II-III stages.
