Short-Term Outcomes of a Reinforced Greater Trochanter Stabilization Technique in Revision Total Hip Arthroplasty After Periprosthetic Fracture: A Novel Technique and Case Series.

This preliminary study introduces a novel surgical technique for short-term fixation of greater trochanter fractures, in periprosthetic fractures, using nonabsorbable sutures and a metal cable, supported by a case series of 6 patients. The technique employs a 1.8-mm cable and 3 #5 nonabsorbable sutures, anchored through the trochanter and secured at the abductor tendon, with sequential tying to ensure stability. Among the 6 patients (mean age 77.3 ± 9.2 years), all demonstrated callus formation of the trochanteric fragment at final follow-up, with minimal migration relative to initial postoperative imaging (mean 2.1 ± 2.3 mm). At follow-up, ambulatory status included: 2 patients using walkers, 1 wheelchair-bound (preoperatively), and 3 ambulating independently. These outcomes suggest that this technique reduces hardware reliance and improves load distribution, promoting functional recovery.
