Background: Though elderly patients with hip fracture were once operated with
cemented bipolar hip arthroplasty (BHP) under management by anesthesiologists,
Orthopaedic surgeons recently have to do both management and operation under
spinal anesthesia except for high-risk patients due to the shortage of
anesthesiologists. In the effort to reduce intraoperative risk caused by using bone
cement, we have been using cementless BHP. The aim of this study is to clarify
clinical results and radiographic features regarding to the cementless BHA in the
osteoporotic patients. Methods 79 patients were evaluated since August 2007 when
cementless BHA under spinal anesthesia started. Postoperative evaluation was
undertaken as to clinical parameters (age, postoperative ADL and such) as well as
radiographic features (canal flair index, subsidence of femoral stem, spot weld,
etc.)Results: The mean age at surgery was 78.7 years. The mean canal flair index
was 3.7. The mean subsidence of femoral stem was 4.4 mm. One hip was dislocated
for postoperative significant subsidence of femoral stem and needed re-operation
with cemented BHA. Postoperative ADL could attain to walk at 79% and to transfer to
chair at 17%. Discussion: Postoperative subsidence of femoral stem was greater
than expected. However, postoperative ADL have been also acceptable results for
the cases of significant subsidence. There was no significant relationship between
preoperative parameter and postoperative excessive subsidence. Conclusions:
Acceptable clinical results were provided with cementless BHA for elderly
osteoporotic hip fracture. Nevertheless, the possibility of causing serious
postoperative complications is yet to be solved.
