![]() ![]() However, distally fixed stems are prone to complications such as femoral stress shielding, periprosthetic fracture, prosthesis subsidence, nonunion, and fracture or migration of the osteotomy fragment. As ETO results in diminished proximal femoral support, distally fixed stems are often implanted for femoral reconstruction and to achieve immediate and reliable distal fixation. Level of evidence Level IIb, Prospective self-control study.Įxtended trochanteric osteotomy (ETO) is often used in revision total hip arthroplasty (rTHA) to remove the prosthesis and protect the femoral cavity, which has the advantages of good exposure, correction of deformity and easy healing. The revision stem enabled restoration of proximal bone stock in femurs with prerevision bone defects, which were prepared for the next revision operation. This stem had excellent clinical and radiographic outcomes, resulting in a high rate of ETO union and stem survival. ![]() ConclusionĬorail revision stems are a viable and reliable option in rTHA with ETO. Two patients had transient thigh pain postoperatively. Forty-three hips had regeneration in the proximal femur. Fifty-nine hips had bony ingrowth from the osteotomy fragment to the stem without radiolucent lines. Sixty-two patients who underwent ETOs achieved complete healing at the final follow-up. The mean follow-up duration was 34 months (range 23–41). These results were used to analyze ETO union, Engh scores, bone remodeling, stem stability and hip function. We performed a postoperative follow-up of the patient and obtained radiographs and Harris hip scores (HHSs). Sixty-four patients undergoing rTHA with ETO using the Corail revision stem between 20 were enrolled in the study. The prospective multicentric study aimed to assess the clinical and radiographic outcomes, and complications of using the Corail revision stem in rTHA with ETO. The distally fixed stem used in revision total hip arthroplasty (rTHA) with extended trochanteric osteotomy (ETO) is subject to periprosthetic fracture, stem subsidence, and stress shielding.
