ABSTRACT

Introduction: femoral lengthening using an intramedullary nail is one of the surgical options in the treatment of severe lower limb dysmetria in routine clinical practice. Material and methods: a retrospective descriptive study was carried out on a series of five patients with a mean age of 15.4 years, who underwent femoral lengthening surgery using a Precice® intramedullary nail. The etiology in all cases was idiopathic. Preoperative and definitive postoperative theoretical lengthening or dysmetry was measured, as well as lengthening accuracy, distraction rate and index (mm/day and days/cm, respectively) and consolidation index (days/cm). Intraoperative and postoperative complications were identified in all cases. Results: mean follow-up was 21 months (12-42), with no loss to follow-up. The mean duration of the surgical procedure was 126 minutes (105-160). The preoperative theoretical dysmetry was 38 ± 2.7 mm. The final mean lengthening was 41 ± 7.5 mm. The mean accuracy was 108% (91-125) and the distraction rate was 0.9 ± 0.4 mm/day. The distraction rate was 13.9 ± 5.1 days/cm and the consolidation rate was 26.6 ± 9.1 days/cm. Bone consolidation was observed in all patients with a mean of 113 ± 58 days. Regarding complications, a total of four minor muscular complications were found. Conclusion: the Precice® intramedullary nail is a good treatment option for cases of severe femoral shortening, providing good clinical and radiological results with a low rate of complications and implant failure.
