Jamshidi K, Mirkazemi M, Gharedaghi M, et al. - This study was sought to compare between bipolar hemiarthroplasty and total hip arthroplasty in allograft-prosthesis composite reconstruction of the proximal femur following primary bone tumour resection. Researchers designed a retrospective study including a total of 57 individuals who had undergone APC reconstruction of proximal femur following the primary tumour resection, either using bipolar hemiarthroplasty (BHA) (29) or total hip arthroplasty (THA) (28). The Musculoskeletal Tumour Society scoring system and Harris Hip Score were applied to assess functional outcome. They further compared postoperative complications of the two techniques. The functional outcome was significantly superior, although the dislocation rate was not higher in THA than with BHA. According to the findings, THA was recommended in APC reconstruction of the proximal femur.
