Title: Possibilities of joint preserving surgery in patients with the developing dysplastic coxarthrosis

Abstract

Introduction: The significance of pelvic and femoral osteotomies in the condition of developed arthrosis is still disputable. Early osteoarthritis and dis-congruency of the articular surfaces are evaluated by many specialists as contra-indication for the joint preserving operation. Purpose: Review middle term results of reconstructive treatment in adolescents and young adults with dysplastic coxarthrosis

Materials and methods: Treatment outcomes of 35 patients with dysplastic coxarthrosis were analyzed. Mean age at intervention was 16 years (14-32). The grade of arthrosis in joints were assessed according to Tonnis: I – 22, II - 10, III - 3. The type of congruence of articulare surfaces were assessed according to Coleman: I- 12, II-9, III -8, IV – 6. All subjects underwent extraarticulare hip reconstruction with the Ilizarov apparatus included pelvic and femoral osteotomies.

Results: Outcomes were followed from 3 to 12 years. Functional outcomes according to Merle d'Aubigne-Postel were: Pain 4,7±0,1 points. ROM – 4,1±0,2 points. Walking ability – 4,6±0,1 points. Radiographic findings according to Severin were: II? - 20, IIb - 11, III – 4. The congruence of articular surfaces improved in 14 joints, remained unchanged in 20 joints, worsened in one joint. Distribution of joints by type of congruence: I - 18, II-1, III - 14, IV – 2. The grade of arthrosis was unchahged in 25 cases, progressed one grade in 3 joints, reduced in 4 cases. Considering clinical and radiological picture the positive outcomes made up 82%.

Conclusions: application of reconstructive operations with Ilizarov frame allows to extend fairly the indications for extra-articular reconstructive invasions in dysplastic coxarthrosis. Improved congruence of the articular surfaces in conditions of osteoarthritis in most cases leads to a slowing of progression.
