Calculation and application of a safe range of load on the limb in patients after osteosynthesis of the femoral neck.

Background: Fractures of the femoral neck occupy a leading place in the total injury rate in the Russian Federation. Despite significant advances in the field of osteosynthesis of femoral neck fractures, there is still a high percentage of unsatisfactory treatment outcomes, including the cases when functional load is applied in the early activation of patients. Therefore, it is very important to find ways to dose the load on the operated limb in the postoperative period in patients with fractures of the femoral neck. The aim of the study is to demonstrate the successful experience of calculating and applying a safe range of load on the limb in patients after osteosynthesis of the femoral neck and substantiate its effectiveness using a universal personalized method of evaluating the results of treatment.

Methods: The study involved 80 patients with fractures of the femoral neck, who had undergone osteosynthesis with various metal structures. A safe range of load on the limb was applied using a method determined by us. The postoperative period results of the selected patients, who formed a comparison group and a study group, were then analyzed using a universal method of personalized evaluation of treatment results. A prospective study was applied.

Results: It was shown that in the study group of 40 patients, using the method developed by us for dosing the load on the limb, 12 months after surgery, 20.5% more excellent and good treatment results were obtained than in the comparison group.

Conclusions: Patients can have a better postoperative outcome owing to the possibility of determining the optimal range of load on the operated limb, which makes it possible to draw up an individual plan for dosing the load from the first day of the postoperative period to the onset of consolidation.
