Abstract:

BACKGROUND: At present, the reports on the application effect of sivash-range of motion (S-ROM) femoral stem prosthesis after total hip arthroplasty (THA) are rare.
OBJECTIVE: To discuss the application of S-ROM femoral stem prosthesis in primary THA.
METHODS: From April 2009 to May 2011, 71 patients (75 hips) were performed primary THA with S-ROM femoral stem prosthesis in the Department of Orthopedic Surgery, the First Affiliated Hospital of Soochow University. The hip functions and the biological fixation effect of the prosthesis were evaluated after the operation.
RESULTS AND CONCLUSION: X-ray films of the 71 patients showed the initial fixed stems were in line with good standard. No infection, fracture, dislocation, deep venous thrombosis or neurovascular injury occurred. The mean postoperative Harris hip score was recovered to (93.8±3.5) points at 6 months after surgery. There was no prosthesis loosening. The S-ROM femoral stem prosthesis has the advantages of reasonable design, strong adjustability and in line with patient anatomy, and it can improve the function effectively.
