TREATMENT OF LOWER LEG FRACTURES WITH LOCKED CENTROMEDULLARY NAILING: 58 CASES

Abstract

Purpose of the study: Locked centromedullary nailing has proven efficacy for the treament of tibial shaft fractures but its use remains controversial for the most distal fractures. The purpose of this work was to assess clinical and radiological outcome of nailing procedures used to treat fractures of the lower quarter of the leg.

Material and methods: Fifty-eight fractures of the lower quarter of the leg were treated by locked centromedul-lary nailing between 1999 and 2002. All patients were included in the analysis. Twenty-four patients aged 44 years on average (range 18–68 years) were reviewed by an independent operator at mean 43.2 months follow-up (range 18–70). Four types of nail were used, on an orthopedic table for 47 procedures and with a hanging leg for 11. The fibula was not fixed.

Results: Early complications were: compartment syndrome (n=2) and infection (n=3). Postoperative alignment was anatomic or good in 86%. Mean time to weight bearing was 66 days (range 0–180). Nonunion occurred in six patients who required revision. Secondary displacement was noted in ten patients. Knee motion was normal in all patients and ankle motion was normal in 80%. Mean time to resumed occupational activity was 5.7 months (range 1–18). At last follow-up, bone healing had been achieved in all patients.

Discussion: As compared with data in the literature, we found that locked centromedullary nailing allows early weight bearing with less risk of infection for radiological results comparable with those obtained with plate fixation. The secondary displacements resulted from defective locking of inappropriately adapted materials (holes insufficiently distal).

Conclusion: Locked centromedullary nailing is a treatment of choice for fractures of the distal quarter of the leg. Use of new nails with more distal holes should improve outcome by allowing distal locking with at least two screws in all cases.
