Thus , while DAA hip arthroplasty can be successfully performed , it is not without complications .
Early complications of anterior supine intermuscular total hip arthroplasty.
Anterior supine intermuscular total hip arthroplasty ( THA ) performed on a fracture table has been increasingly used for primary THA . Accurate cup placement , low incidence of dislocation , shorter hospital stay , and faster return of function are potential benefits of the technique . However , a high complication rate , particularly during a surgeon 's learning curve , has been reported . A retrospective analysis of 61 consecutive anterior supine intermuscular primary THAs with at least 6-month follow-up was performed . All procedures were performed using the anterior supine intermuscular approach with cementless implants under fluoroscopic guidance on a fracture table . Prospect ively collected data were retrospectively review ed to evaluate the early complication rate and radiographic accuracy of implant placement . Five ( 8.2 % ) intraoperative complications were observed : including 3 trochanteric fractures and 2 calcar fractures , 4 of which required cable fixation during the index procedure . One nondisplaced trochanteric fracture was treated conservatively . One patient sustained an injury of the lateral femoral cutaneous nerve . Postoperative complications included 1 anterior dislocation , 1 infected superficial hematoma , 1 stem subsidence , and 1 loose stem , with the latter 2 presenting as increasing thigh pain postoperatively and requiring stem revision . The overall complication rate was 16.4 % ( 10/61 ) . Overall , 3 patients ( 4 hips ; 6.5 % ) required reoperation . No femoral or sciatic nerve injuries occurred , and no patient was diagnosed with venous thromboembolism . All intraoperative fractures occurred during the first 32 cases , and none during the last 29 cases . A potentially high incidence of complications with the anterior supine intermuscular THA exists during a surgeon 's learning curve in an academic setting
Thus , while DAA hip arthroplasty can be successfully performed , it is not without complications .
