Summary:
The aim: to analyze locomotor function of lower limbs in patients with dysplastic coxarthrosis Crowe IV type before and after single-step hip joint endoprosthesis and femoral bone osteotomy conducted by our own technology. Material and Methods. 42 patients with one-side dysplastic coxarthrosis Crowe IV type were examined and operated. The mean age at the time of admission in men was 47.3±1.2 years, women — 46.1 ±1.1 years. Static and kinematic function of lower limbs was evaluated with the help of stabilometrics and podometry before and one year after the operation. Results. Before treatment, the patients had deviations of static and dynamic function of locomotor system stabilometri-cally seen as instability in upright position and podographically as a compromised gait. One year postsurgically we indicated static balance between the limbs within the normal range, expanded motoring mode, which was supported by significant improvement in the biomechanical characteristics of locomotor function of the patients. Conclusion. Total hip replacement in combination with modifying osteotomy of the hip conducted by a unique technique restores static and kinematic function of lower limbs in patients with high congenital hip dislocation (dysplastic coxarthrosis Crowe type IV) which is proved by stabilographic and podographic indices one year after operation.
