Abstract:
[Objective] To investigate the effect of one-stage bilateral hip replacement in the treatment of late stage of hip joint ankylosis.[Methods]Ninteen patients(38 hips)with hip ankylosis were taken as research samples.Patients underwent biologically total hip replacement with posterolateral incision and acetabular plastic repair after second osteotomy.The ankle between acetabulum and femoral body was modulated according to the pre-operative deformation.A larger artificial prosthesis was installed.Early functional exercises were taken after operation.[Results]All cases were given a mean follow-up of 5.5 years(1~8 yrs).Dislocation was found in 2 cases and recovered after manual reduction.Slight fissure fractures were found in 2 hips and no special management was given.Slight heterotopic ossification was found in 6 hips,with grade Ⅰ in 3 hips,grade Ⅱ in 3 hips according to Brooker Classification.No obvious functional influence was found.The flexion-extension range increased from 0? pre-operation to average 81?(65?~115?)and the mean moving range reached 160?(110?~230?).[Conclusion]Bilateral hip replacement is a good method to reconstruct the hip function,promote the living standard.Artificial joint damage in the traditional two stage operations was avoided.It also has advantages of less medical expenses for patients and less pain after surgery.Functional exercises could be started earlier.It is a satisfactory method for the treatment of hip joint ankylosis.
