Abstract
Introduction: The management of young adults with severe osteoarthritis of the hip still remains a problem because of the increased failure rates of total hip arthroplasty in this active high demanding individuals. Hip arthrodesis if done with proper patient selection and proper arthrodesis position provide a viable alternative with good functional results. Objective: The objective of our study was to review the functional outcome after hip arthrodesis and to review its implications on patientñs general life. Material & methods: In our retrospective study we reviewed thirteen patients (5 males,8 females) who had hip arthrodesis at an average age of 30 years. Indications include Septic arthritis, T.B, A.V.N and osteoarthritis secondary to trauma. Cobra Head plate Technique was used. The mean follow up was 15.2 years. All cases had union at the time of followup. SF 36 and Modiþed Harris hip score was used to assess the functional outcome. Isokinetic muscle strength was measured using Cybex machine. Results: Solid arthrodesis was noted in all cases at follow-up. 50% of cases complained of back pain and only one patient complained about ipsilateral knee pain. The average Haris hip score was 76.
The average deþcit in extension torque in the involved leg was 46% and average deþcit in ßexion torque was 4%. The differences in torque were compared using a t-test and extension difference was found to be statistically signiþcant (p< 0.0001). Female patients did well as well as male patients with 70% having no major difþculties in sexual relationship. Ten out of 13 were satisþed with the operation but 7 of 13 would undergo it again given the alternative of total joint arthroplasty. Conclusion:We conclude that hip arthrodesis is still a viable alternative procedure in carefully selected patients.
