Follow Up On The Early And Long Term Outcome Of45Cases With Total Hip Arthroplasty For Femoral Neck Fractures Due To Osteoporosis

Objective To investigate the effect of osteoporotic femoral neck fractures with total hiparthroplasty.Methods We reviewed the short and long term outcome of45cases of osteoporoticfemoral neck fractures in patients undergoing total hip replacement line for the studyfrom March2008to March2011period with complete data of. The diagnosis andtreatment was made by standard and a retrospective analysis of clinical data and follow-up results, were conducted. Furthermore, this study discuss recent and long-term efficacyof osteoporotic femoral neck fractures with total hip arthroplasty to provide the basis forthe choice of surgical indications, but also provide a basis for avoiding surgicalcomplications and improve the success rate.Results According to Garden classification of femoral neck fracture method will bedivided into four types:①GardenI②GardenII③GardenIII④GardenIV. Thisstudy selected osteoporotic femoral neck fracture and mainly type IV III, whichGardenIII type （complete fracture, partial displacement）17cases, IV type（complete fracture completely shift） in28cases. After six months of follow-up, wefound in45cases of osteoporotic femoral neck fracture, Harris hip score was excellent95.6%, Merle d’Aubigné classification of joint function excellent rate was95.6%also. Alocal allergy and2inflammation ocoured and wound infected in one case. Three cases ofpulmonary infection, two cases o anemia were followed by surgery. One case of urinarytract infection and deep vein thrombosis in1case were recorded. One case of dislocationwas recorded and underwent secondary surgery. After3years of follow-up, we foundthat patients with excellent Harris hip score was84.4%and reoperation rate was8.9%（4/45） and Merle d’Aubigné classification of joint function excellent rate was88.9%.Dislocation happed in one case and the joint prosthesis loosening occurred in two casesof subsidence and bedsores followed in two cases.Conclusions Total hip arthroplasty GardenIII type （complete fracture, partialshift） and Type IV （complete fracture completely shift） osteoporotic femoralneck fractures and achieved good results. Fewer complications can be controled.Mobility and quality of life of patients have obtained satisfactory results.
