title: Enhancing soft tissue ingrowth in proximal femoral arthroplasty with aortograft sleeve: a novel technique and early results.
abstract: Hip abductor function is critical to joint stability after proximal femoral arthroplasty. Normal soft tissue relationships are often violated during this procedure for complete tumor resection. Abductor insufficiency leads to abnormal gait mechanics and poor function. To improve soft tissue stability about a metallic proximal femoral endoprosthesis, we devised a novel use of vascular graft material. Two patients received a proximal femoral arthroplasty using this technique. These patients were followed for an average of 26.5 months. They demonstrated mean active hip abduction of 48°, hip flexion of 90°, mean Musculoskeletal Tumor Society score of 24 (80%), and Toronto Extremity Salvage Score of 80. We believe that this technique may be useful in achieving soft tissue stability about a metal endoprosthesis and may facilitate better function in patients undergoing this surgery.
