Abstract:
BACKGROUND: The optimal total hip replacement can be prepared by assembling S-ROM prosthesis individually. OBJECTIVE: To evaluate the short-time effect of S-ROM prosthesis total hip replacement for osteoarthritis secondary to developmental dysplasia of hip. METHODS: Totally 57 adult patients (63 hips) with osteoarthritis secondary to developmental dysplasia of hip treated by S-ROM prosthesis for primary total hip arthroplasty from November 2002 to February 2007 were selected. The preoperative and postoperative Harris score were compared. The prosthesis loosening, fracture and subsidence, bone absorption and fracture were followed-up with radiographic results. RESULTS AND CONCLUSION: All patients were followed up from 6 months to 5 years, mean 3.5 years. One patient suffered temporary common peroneal nerve palsy, and recovered after 4 months. One patient suffered hip dislocation, and recovered after manipulative reduction and traction. There were no complications in the rest patients. The Harris hip score was 70.20-92.10, mean 88.30, which was obvious increased than that of before operation (P < 0.05). No loosening, fracture and subsidence of prosthesis, bone absorption or fracture was observed. The results demonstrated that S-ROM prosthesis total hip replacement can receive an excellent short-time effect in treating osteoarthritis secondary to developmental dysplasia of hip.
