[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.
