Minimally invasive intermuscular approach does not improve outcomes in bipolar hemiarthroplasty for femoral neck fracture
Background Minimally invasive surgery ( MIS ) can lead to early recovery , but its postoperative effect is short after total hip arthroplasty for osteoarthritis . Because bipolar hemiarthroplasty ( BHA ) for femoral neck fractures is preferred for elderly patients , early functional recovery may prevent the rapid progression of disuse atrophy , and an MIS surgical approach may improve subsequent hip joint function . Methods MIS-BHA was performed using the direct anterior approach , without muscle or tendon detachment . A total of 83 patients who underwent BHA from April 2007 to February 2009 were assigned to MIS-BHA or conventional BHA . Selection of patients for MIS-BHA was not r and omized . Hip joint function was evaluated with the Hospital for Special Surgery ( HSS ) system at 1 month and 1 year after surgery . Results There were no significant differences in age , sex , height , weight , body mass index , time from admission to surgery , or preinjury HSS scores between two groups . HSS scores were higher with MIS-BHA ( 24.2 vs. 20.2 ; P = 0.01 ) at 1 month but were similar 1 year after surgery ( 29.9 vs. 27.2 ; P = 0.10 ) . Conclusions The effectiveness of MIS-BHA for femoral neck fracture is limited to the early postoperative period . Therefore , MIS-BHA does not appear to be appropriate for treatment of femoral neck fractures
Thus , while DAA hip arthroplasty can be successfully performed , it is not without complications .
