Hip joint dysplasia is a deformation of the articular elements (pelvic acetabulum, head of the femur, and/or ligament of the head of\nthe femur) leading to laxity of the hip components and dislocation of the femoral head from the pelvic acetabulum. Diagnosis\nis based on symptoms observed during clinical and radiological examinations. There are two treatment options: conservative\nand surgical. The classic surgical procedures are juvenile pubic symphysiodesis (JPS), triple pelvic osteotomy (TPO), total hip\nreplacement (THR), and femoral head and neck resection (FHNE).Theaimof this experiment was to present an original technique\nof filling the acetabulum with a polypropylene implant, resting the femoral neck directly on the mesh. The experiment was\nperformed on eight sheep.The clinical value of the newsurgical technique was evaluated using clinical, radiological, and histological\nmethods. This technique helps decrease the loss of limb length by supporting the femoral neck on the mesh equivalent to the femoral\nhead. It also reduces joint pain and leads to the formation of stable and mobile pseudarthrosis.Themesh manifested osteoprotective\nproperties and enabled the formation of a stiff-elastic connection within the hip joint. The method is very cost-effective and the\ntechnique itself is simple to perform.
