Conservative femoral revision using short cementless stems with a tapered rectangular shape for selected Paprosky II–IV bone defects: an average seven-year follow-up

The use of long stems for severe femoral bone defects is suggested by many scholars, but it is associated with further bone loss, intraoperative fracture, increased surgical trauma, and complications. With better bone retention, simple and quick surgical procedures, and minimal complications, the short cementless stems with a tapered rectangular shape may be an alternative for femoral revision. This study aimed to evaluate the results of this type of stem in treating selected Paprosky II-IV bone defects.
