Abstract

Objective: Comment on the initial results of developmental dysplasia of the hip treatment by total hip arthroplasty. Subject and method: This is a clinical descriptive study, with vertical follow-up and no control group study. 6 patients, including 5 females and 1 male, with developmental dysplasia including 6 hips were operated with total hip arthroplasty at the Joint Surgery Department of 108 Military Central Hospital from April 2018 to July 2022. The age range was 22 to 59 (average 39.1). The mean follow-up period was 37.5 months (ranged from 9 to 60 months). Result and conclusion: The average Harris score post-operation was 89.8 ± 7.1, significantly improved compared to 33.7 ± 4.7 pre-operation. 5/6 of cases used cement-less cup, 1 case used a compound of cement and liner polyethylene directly to the acetabulum. 1 case we had to perform proximal femur shortening. Three patients complained about limb length discrepancy. Two patients suffered temporary sciatic nerve paralysis post-operation.
