Clinical and radiological evaluation of hybrid hip replacement in various disorders of hip

Background: High rates of loosening of cemented implants led to change in technique of fixation of the implant. Methods: Fifty-nine hips were operated in 42 patients with non-cemented acetabular and cemented femoral components between January 1999 and July 2003. The average age of the patient was 45.2 years in our study. Preoperative diagnosis was avascular necrosis (28), ankylosing spondylitis (18), fracture neck femur (9), rheumatoid arthritis (2) and osteoarthritis (2). Results: At an average follow up of 3.6 years (range 1.2-5.8 years) excellent to good results were obtained 92% according to Harris hip criteria. No radiological loosening was noted in any femoral or acetabular component on follow up. One poor result was seen in a case of bilateral ankylosing spondylitis operated on one side. Conclusion: Hybrid THA provides a viable and highly acceptable method of treatment of diseases of hip in young patients.
