Reverse hybrid total hip arthroplasty, a good alternative to uncemented total hip arthroplasty

Abstract

Total hip arthroplasty is the treatment of choice for primary and secondary arthritis of the hip joint. Uncemented total hip is the implant of choice in young adults with good bone stock in the acetabulum and femur. Correspondingly, cemented implants are preferred in patients with poor bone quality and in elderly. Uncemented prosthesis are relatively expensive when compared to cemented but have longer viability. A prospective study conducted at Vydehi institute of medical sciences between July 2016 and may 2018 on 21 patients using reverse hybrid total hip arthroplasty and follow up was done post op, 6, 12, 24 weeks and 1 year post operatively. Functional outcome assessed using Modified Harris Hip score. The data was analyzed using a Chi square test for equal proportions was applied for categorical variables and Independent sample t test was applied. The mean pain score during pre-operative period was 11.43±3.59 and during post-operative period was 41.71± 4.26. The difference between the pre and post-operative pain scores was statistically significant. The mean functional gait score during pre-operative stage was 10.24±8.23 & during post-operative stage was 41.71 ± 4.26, the t value corresponding to this mean difference was -8.609 and its corresponding p value was 0.000
