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.

Summary:

In the course of the study the foreign and native publications concerning total hip replacement have been analyzed. The data from National Registers of various countries are presented in the study. They highlight some issues upon total hip replacement, technologies of surgical intervention advancing and most important risk factors for endoprosthetic ball dislocation.

Morphometric justification of algorithm of the choice of method of surgical treatment of dysplastic coxarthrosis

Summary:

Purpose: to define regularities of variability of bone structures of a hip joint depending on type of dysplastic coxarthrosis and to develop tactics of total endoprosthesis replacement. Objects of research. 106 patients with dysplastic coxarthrosis of varying severity, passing treatment on the basis of Federal State Budget Institution of Saratov Scientific Research Institute of Traumatology and Orthopedics from 2005 to 2014 applying methods X, KT-, MRT-metry variation and statistical methods. Results: According to anatomic features of a hip joint at dysplastic coxarthrosis of various types algorithms of choice of acetabularand femoral components of endoprosthesis, and also tactics of total endoprosthesis replacement in groups of research are developed. Conclusion. The choice of a standard size of an endoprosthesis of a hip joint needs to be carried out taking into account X-ray anatomic features of a hip joint and degree of expressiveness of the dysplastic changes. At dysplastic coxarthrosis of the l-ll types it is necessary to carry out standard total endoprosthesis replacement; at coxarthrosis of the III type —total endoprosthesis replacement in combination with plasticity of a roof of acetabular hollow; at coxarthrosis of the IV type — total endoprosthesis replacement in a combination from the shortening femur osteotomy.

X-ray, anatomical and biomechanical features in patients with developmental hip dislocation

Year: 2014, volume 10 Issue: №1 Pages: 114-119

Organization: Saratov State Medical University
Summary:

The Pupose: to analyze X-ray, anatomical and biomechanical features in patients with developmental hip dislocation. Material and Methods. The study included 73 patients (57 women and 16 men) with the developmental hip dislocation at the age of 31 to 76 years. The clinical method, X-ray, gait analysis and visual analogue scale VAS, McGill inquiry. Results. The comparative analysis of X-ray, anatomic and biomechanical features in patients with different severity of developmental hip dislocation. Conclusion. Features of the functional status of patients with different severity of developmental hip dislocation enable to predict the tactics of surgical treatment and individual rehabilitation program.
