Abstract:
Objective To explore operative indications,methods and effect of one stage total hip arthroplasty(THA)in treatment of acetabular fractures.Methods One stage total hip arthroplasty (THA)was carried out in 11 patients with acetabular fractures including 10 males and one female(at mean age of 42.4 years)8-37 days(mean24 days)after injury.There were anterior column fractures in three patients,posterior wall fracture in one,posterior column fracture in two,posterior column fracture combined with posterior wall fracture in two,transverse fracture in one,transverse fracture combined with posterior wall fracture in one and two-column fracture in one.Fresh acetabular fractures were first fixed with reconstruction plate or screws to restore shape of acestbular wall;then,granule or bulk of resected femoral head were implanted into acetabulum posterior to placement of acetabular cup prosthesis.While for old acetabular fractures,the resected femoral head was first implanted on acetabular superior wall and posterior wall and then acetabular cup prosthesis was placed.Results Follow-up for 6-45 months (mean 28 months)showed obdous improvement of hip joint function,with average Harris score of 78 points and average active degree of 95°.X-ray film presented loosening of acetabulum and osteolysis in one patient.All patients began weight bearing three months after operation,with no dislocation of joint prosthesis.Conclusions Under strict control of indications,one stage THA can be done for patients who miss operative reduction due to obvious acetabular fracture dislocation and severe articular cartilage injury.Stable aeetabular cup may beget satisfactory short-term clinical results.
