Abstract
Introduction & aims
Total hip replacement is an excellent treatment option for people with late stage degenerative hip disease. In addition to marked reduction in pain and improvement in sleep, most people regain range of motion, physical ability and quality of life. This study aimed at the functional outcomes of large diameter heads in THR patients.
Method
This study is an analysis of a cohort of patients undergoing total hip replacement performed at our hospital from November 2011 to July 2013. A total of 70 hips, 40 males and 30 females, were operated upon with large diameter femoral heads. The mean age was 50.38 years (range 40–59 years). In our cohort, 32 patients had AVN of femur head, 19 had post traumatic secondary degeneration, 10 had RA, 6 had AS and 3 patients had OA of hip. The follow-up data included local complications, Harris Hip Score, medical complications, readmission, activity status and use of a walking aid.
Results
Harris hip score at final follow up was, 33 cases had excellent, 26 cases had good result. None of the patient had fair or poor result. Two cases of superficial infection were observed. One case of dislocation was observed in post operative period which was reduced under GA and patient was given abduction brace. The mean follow up was 16.31 months ranging from 6 to 32 months. During the follow up, we had mortality of two patients. One died at 14 months due to myocardial infarction and the cause of other died due to CVA at 10 months follow up.
Conclusions
Lower dislocation rate and better range of motion in majority of cases reinforces the advantage of large diameter head in THR in young and active patients.
