Fijación con placa bloqueada y aumento con aloinjerto de peroné para fracturas pertrocantéreas fallidas: una nota...

The failure cases of peritrochanteric fractures are occasionally encountered due to poor bone stock. For proximal humeral fractures, a strategy using a segment of the fibular allograft (FA) placed endosteally was introduced. Several studies have demonstrated favorable outcomes with FA. Inspired by this, a fixation strategy using FA with a locking plate was performed in patients with unfavorable bone stock conditions. Ten patients with poor bone stock and nonunion of peritrochanteric fractures were treated with FA and a locking plate at a tertiary hospital between 2016 and 2022. We analyzed the bone union status, the time taken for union, and postoperative complications. Bone union was achieved in all cases following average time of 9.6 months (range 6-14 months). There was no complication related to allograft such as infection. The use of FA in conjunction with a locking plate for fixation in nonunion of peritrochanteric fractures with poor bone stock or cortical bone defects demonstrated successful outcomes in our study. Ongoing observations and reporting are essential for comprehensive validation and addressing potential complications.
