Abstract:
Objective To discuss the short-term outcomes of uncemented APL stem hip hemiarthroplasty for unstable intertrochanteric fracture in elderly patients.Methods From July 2008 to December 2011,26 cases of intertrochanteric fractures were treated by hemiarthroplasty using uncemented APL stem.There were 10 men and 16 women with a mean age of 82.5 years (range,75-94 years).According to EvansJensen classification system,16 cases were type Ⅱ fractures,the other 10 were type Ⅲ.Results The mean operation time was 56 min (range,48 to 72 min).The average blood loss during the operation was 360 ml (range,240-600 ml).One of the patients died in the perioperative period,2 died during the follow-up.The other 23 patients were followed up with an average of 21.5 months (range,12-42 months).The patients were encouraged to walk with aid about 2-3 weeks postoperatively.Three months after the operation,the walking ability were almost recovered to pre-injury level in 21 cases.The acetabular wear,the prosthetic loosening and subsidence were not found.The complications included 1 case of cerebral infarction,1 case of deep venous thrombosis,2 urinary infection,1 skin ulcer due to the long-term use of cortical steroid and 2 heterotopic ossifications.According to Harris hip score,12 cases were classified as excellent,10 cases as good and 1 case as fair.Conclusion Hemiarthroplasty using uncemented APL stem is an effective way to treat the unstable intertrochanteric fracture in elderly patients.The quality of life of the elderly patients can be improved due to early mobilization after the surgery.
