Various approaches have been implemented to enhance bone regeneration, including the utilization of autologous platelet-rich plasma and bone morphogenetic protein-2. The objective of this study was to evaluate the impact of Marburg Bone Bank-derived bone grafts in conjunction with platelet-rich plasma (PRP), recombinant human bone morphogenetic protein-2 (rhBMP-2), and zoledronic acid (ZA) on osteogenesis within rabbit bone defects.

The influence of rigid fixation and permanent compression on the results, the timing of fusion and rehabilitation after fractures of the femoral neck was investigated.

A hip fracture is 60–80% of all fractures of the proximal femur. Despite recent advances in the treatment of this disease, the percentage of unsatisfactory outcomes as high as 25–35%. The choice of surgical treatment in femoral neck fractures in the elderly remains as controversial as it was almost 50 years ago when Speed called him as “the unsolved fracture. Hip replacement is currently the gold standard in the treatment of femoral neck fractures. But compared with the osteosynthesis operation takes more time, is accompanied by massive blood loss, sometimes the need for transfusion and a higher risk of deep wound infection. Given these facts the best is an indoor low-traumatic method of osteosynthesis locking.

Compare of the results of femoral neck fractures using of osteosynthesis 3 blade nail, spongious screws and nail for permanent compression.

A retrospective analysis of treatment of 252 patients from 1982 to 2015 with subcapitale and transcervical fractures of the femoral neck on the basis “RCTO named by H.J. Makazhanova”. In the research locales patients older than 40 years. All patients were divided according to the applied method of treatment: 1 group of 95 patients operated using a 3-blade-nail, in the 2nd group of 105 patients operated on spongious screws, in the 3 group of 52 patients operated nail for the permanent compression, authoring. All patients underwent x-ray examination before and after surgery. The average period from time of injury before performing the osteosynthesis amounted to 4–7 days. The follow-up period was 6–12 months. The results obtained clinically and radiographically divided into good, satisfactory, poor. Good and satisfactory results were regarded as positive, and poor results as negative.

The average age of patients was 67.5 years. Among these female patients − 174 (69%), the male − 78 (31%). Traumatization more prone to elderly accounting for 206 (81.7%) cases, and only 46 (18.3%) in the middle age group. Analysis of the results of treatment showed positive results in 1 group − 69.5 %, in group 2 − 83.8 %, in group 3 − 96.2 %. In the first group of 29 (31.5 %) and in the second group of 17 (16.2 %) patients have postoperative complications: secondary displacement, nail migration, pseudarthrosis, necrosis of head. The patients of third group have postoperative complications in 2 cases (3.8 %): displacement of bone fragments according of retraumatization. Employability was restored in 1 group − 7–9 months, in group 2 - in 6–8 months, 3 group - through 6–6.5 months.

The method of choice for fresh fractures of the femoral neck, especially subcapital fractures in the elderly, is a minimally invasive method of closed compression osteosynthesis.
