Abstract:
The dysplastic hip presents problems to the orthopedic surgeon in the reconstruction of hip using total hip prosthesis. The use of bone grafts to reconstruct the lateral acetabular bone deficiency is very popular. We investigated in 23 patients(5 cemented cup and 18 cementless cup). Sixteen patients were women and seven were men, whose average age was 42.4 years old; their average followup was 4.6 years. The average Harris hip score improved from a preoperative value of 48 points to a postoperative value of 87 points. Five cases showed radiographic loosening, in which 3 cases loosening from five cemented cup and 2 cases from cementless cup arthroplasty. Radiolucent lines were observed more frequently with cemented cups at last follow-up. Of the 23 cases, 18(78%) was successful. Postoperatively limping was a major problem because most patients in this series had unilateal disease. The grafted bone was incoporated by an average time of 7.4 months, and minor resorption was showed at last follow-up. In our series, cementless cups with autogenous bone graft noted good results than cemented cup arthroplasty.
