"literature article entitled, ¿a minimal-incision technique in total hip arthroplasty does not improve early postoperative outcomes¿ by luke ogonda, mrcs, et al, published by the journal of bone and joint surgery (2005), vol.87-a, no.4, pp.701-710, was reviewed.The objective of this study was to compare the results of a single mini-incision approach with those of a standard-incision total hip arthroplasty in the early postoperative period in 219 hips between december 2003 and june 2004.Implanted depuy products: all patients underwent a hybrid tha which included a cementless pinnacle cup and either an xpress rapid custom or c-stem cemented cup.The manufacturer of the cement is unknown.The authors do not provide information regarding the acetabular liner or femoral head.The femoral head and acetabular liner are assumed to be depuy products.Results: there were no recorded revisions during the follow-up period.1 intraoperative acetabular fracture- no treatment required and no postoperative patient consequences.1 intraoperative femoral fracture- no treatment required and no postoperative patient consequences.5 cases of postoperative hypotension that required medical intervention and postponed the patient¿s ability to comply with physiotherapy protocol.1 case of acute renal insufficiency that postponed the patient¿s ability to comply with physiotherapy protocol.The condition resolved with medical intervention that did not require dialysis.2 cases of severe postoperative nausea that required medical intervention.11 mispositioned femoral stems- no treatment required.1 deep infection treated with irrigation and debridement and 6 weeks of iv antibiotics.1 superficial wound infection treated with antibiotics.2 early dislocations treated with closed reductions.1 deep vein thrombosis- treatment unknown 1 postoperative death due to acute myocardial infarction.This patient had preexisting ischemic heart disease and a history of angioplasty.The authors do not attribute this death to the surgical procedure or the implanted tha.This death will not be included in the complaint.1 death due to extensive bowel infarction due to mesenteric vessel thrombosis.There is insufficient information provided to conclusively determine the cause of the postoperative mesenteric thrombosis.Therefore, this death is included in this complaint.Captured in this complaint: pinnacle cup, head, liner, and stem for death.Pinnacle cup: no reported product problem.Acetabular liner: implant dislocation.Femoral head: implant dislocation.Femoral stem: implant misposition.Patient harms: blood pressure abnormal, nausea, infection, wound infection, surgical intervention, joint dislocation, deep vein thrombosis, bowel infarction, thrombosis.There is insufficient information provided to attribute the renal insufficiency to the implanted products or the surgical procedure.The femoral and acetabular fracture required no intraoperative intervention and caused no postoperative patient consequences.".
