Regarding the optimal surgical approach,two recent meta-analyses have found that posterior approaches are associated with: higher rates of dislocation compared to lateral and anterior approaches; and higher rates of re-operation compared to lateral approaches. Posterior approaches should therefore be avoided when performing hip hemi-arthroplasty procedures. Assessing the optimal prosthesis head component,three recent meta-analyses and one Cochrane review have found that while unipolar hemiarthroplasty can be associated with increased rates of acetabular erosion at short-term follow-up(up to 1 year),there is no significant difference between the unipolar hemi-arthroplasty and bipolar hemi-arthroplasty for surgical outcome,complication profile,functional outcome and acetabular erosion rates at longer-term follow-up(2 to 4 years). With bipolar hemi-arthroplasty being the more expensive prosthesis,unipolar hemi-arthroplasty is the recommended option. With regards to the optimal femoral stem insertion technique,three recent metaanalyses and one Cochrane Review have found that,while cemented hip hemi-arthroplasties are associated with a longer operative time compared to uncemented Hip Hemi-arthroplasties,cemented prostheses have lower rates of implant-related complications(particularly peri-prosthetic femoral fracture) and improved postoperative outcome regarding residual thigh pain and mobility. With no significant difference found between the two techniques for medical complications and mortality,cemented hip hemi-arthroplasty would appear to be the superior technique. On the topic of wound closure,one recent meta-analysis has found that,while staples can result in a quicker closure time,there is no significant difference in post-operative infections rates or wound healing outcomes when comparing staples to sutures. Therefore,either suture or staple wound closure techniques appear equally appropriate for hip hemiarthroplasty procedures.展开更多

Bone nonunion and avascular osteonecrosis of the femoral head caused by the internal fixation failure for femoral neck fracture are always the complex topics in orthopedics. With regard to patients who sustain these complications, total hip arthroplasty is a proper choice for elderly patients, but is not acceptable by young patients. We report nine patients with the failure of internal fixation for femoral neck fracture who were treated with free vascularized fibular grafting and internal fixation with cannulated screw from November 2001 to October 2003. All of them achieved good results.展开更多
