Naviculocuneiform joint arthrodesis in a cohort of 36 patients.

Background: Arthrodesis of the naviculocuneiform joint (NCJ) can be performed in isolation or in conjunction with arthrodesis of other joints, often in the presence of deformity. In the literature there is relative rarity of articles reporting on results and complications of NCJ arthrodesis.

Patients And Methods: Thirty-six patients (36 feet) with symptomatic NCJ arthritis underwent arthrodesis. Mean age was 59.1 years (SD 13.1; range 26-78) and 24 were women. Adjuvant procedures were performed simultaneously in 29 patients, whilst 17 had planovalgus and 1 had cavovarus foot deformity.

Results: Union of the NCJ arthrodesis was achieved in 35 out of 36 (97.2 %) patients, whilst one patient developed non-union. Mean time to union was 13.1 weeks (SD 3.8; range 8-24). Two patients (5.6 %) developed deep infection and 5 patients (13.9 %) required secondary surgical procedures. Twenty-three patients (63.9 %) rated the outcome as good or excellent, 11 (30.6 %) as fair and 2 (5.6 %) as poor.

Conclusions: NCJ arthrodesis was part of a more complex procedure in most of the patients. Whilst union was achieved in almost all patients and complication rate was acceptable, only 64 % rated their outcome as good or excellent.

Level Of Clinical Evidence: IV.
