[Arthroplasty of the hip joint using demineralized osteo-cartilaginous allogeneic caps (experimental study)].

The authors have carried out an experimental study of demineralized osteochondrous allocaps (DOCA) for the arthroplasty of the hip joint. The articular cartilage was removed completely in 10, partly from the head in 5 and from the entire cavity in 2 of the 15 rabbits. The animals were excluded from the experiment at various terms (from 2 weeks to 10 months). It has been morphologically determined that when DOCA were employed, the regeneration of the articular cartilage of the head was most complete in cases of its focal resection. When the articular cartilage of the head was completely removed, the cartilaginous regenerate did not possess the mechanical properties of the normal one and was subjected to secondary degenerative and dystrophic changes. The best results were obtained in cases when plasty of the cavity with DOCA was performed. The signs of regeneration of the cartilage under the DOCA and its absence on the surface without the caps testify to chondroinductive properties of DOCA.

[Arthroplasty of the hip joint using biocompatible self-dissolving polymers (an experimental study)].

This study is devoted to experimental investigation of using a polymeric self-dissolving film of N-vinylpyrrolidine and alkylmethacrylate 100 muk to 300 muk in width for arthroplasty of the hip joint. The experiments were carried out on 10 rabbits whose articular cartilage from the acetabulum was removed and the latter was lined with the polymeric film. The animals were excluded from the experiment at different periods (from 2 weeks to 8 months). It was morphologically determined that the use of a biocompatible film leads to the formation of a new cartilage or a cartilaginous regenerate, which at later terms is replaced by fibrillar connective tissue and fibrillar cartilage, while the biocompatible film plays no direct role in the formation of the cartilage and the connective tissue, but contributes to their emergence under the latter as if under protector.

[Arthroplasty of the hip joint in children and adolescents with congenital hip dislocation].

The work is devoted to operative treatment of children with repeated dislocations and ankyloses of the hip joint after operative treatment of congenital dislocation of the hip. The dura mater, demineralized allocups and polymer self-resolving film were used as interlayers. Best results were obtained in arthroplasty with using demineralized allocups, polymer self-resolving film or their combinations.
