Hip joint dysplasia is a deformation of the articular elements (pelvic acetabulum, head of the femur, and/or ligament of the head of the femur) leading to laxity of the hip components and dislocation of the femoral head from the pelvic acetabulum. Diagnosis is based on symptoms observed during clinical and radiological examinations. There are two treatment options: conservative and surgical. The classic surgical procedures are juvenile pubic symphysiodesis (JPS), triple pelvic osteotomy (TPO), total hip replacement (THR), and femoral head and neck resection (FHNE). The aim of this experiment was to present an original technique of filling the acetabulum with a polypropylene implant, resting the femoral neck directly on the mesh. The experiment was performed on eight sheep. The clinical value of the new surgical technique was evaluated using clinical, radiological, and histological methods. This technique helps decrease the loss of limb length by supporting the femoral neck on the mesh equivalent to the femoral head. It also reduces joint pain and leads to the formation of stable and mobile pseudarthrosis. The mesh manifested osteoprotective properties and enabled the formation of a stiff-elastic connection within the hip joint. The method is very cost-effective and the technique itself is simple to perform.
髋关节发育不良是关节结构（骨盆髋臼、股骨头和/或股骨头韧带）的一种变形，导致髋关节组件松弛以及股骨头从骨盆髋臼脱位。诊断基于临床和放射学检查中观察到的症状。有两种治疗选择：保守治疗和手术治疗。经典的手术方法包括青少年耻骨联合切开术（JPS）、三联骨盆截骨术（TPO）、全髋关节置换术（THR）以及股骨头和颈切除术（FHNE）。本实验的目的是展示一种用聚丙烯植入物填充髋臼的原创技术，使股骨颈直接置于网片上。该实验在八只绵羊身上进行。使用临床、放射学和组织学方法评估了这种新手术技术的临床价值。该技术通过将股骨颈支撑在相当于股骨头的网片上，有助于减少肢体长度的损失。它还能减轻关节疼痛，并导致形成稳定且可活动的假关节。网片表现出骨保护特性，并能在髋关节内形成刚弹性连接。该方法性价比很高，且技术本身操作简单。
