Intraoperative complications of 175 cementless revision total hip arthroplasties done at four institutions using a porous-coated, uncemented, distally slotted, fluted femoral stem were reviewed. Three types of complications were recorded: eccentric reaming, femoral perforation, and femoral fracture. Intraoperative complications occurred in 16 patients (9.1%). There was no statistically significant association between complication rate and type of surgical approach, stem length, stem diameter, or host bone quality. This complication rate is comparable to or lower than that reported with the use of similar uncemented long femoral revision stems.
