Outcomes of Naviculectomy for Severe Recurrent Clubfoot Deformity.

BACKGROUND

Naviculectomy was originally described for resistant congenital vertical talus deformity but was later expanded to use in rigid cavus deformity. This study reviews the operative outcomes of complete excision of the navicular for recurrent deformity in the talipes equinovarus (TEV) population.

METHODS

After institutional review board approval, all patients undergoing naviculectomy at a single institution were identified. Clinical, radiographic, and pedobarographic data (minimum 2 years' follow-up) were reviewed.

RESULTS

Twelve patients (14 feet) with TEV from 1984 to 2019 were included. All feet had minimum 1 prior operative intervention on the affected foot (mean age = 4.0 years, range 0.2-14.5), with 8/14 having at least 3 prior operative procedures. Complete navicular excision with concomitant procedures was performed in all patients (mean age = 11.7 years, range 5.5-16.1). Mean clinical follow-up from naviculectomy was 5.1 years (range, 2.2-11.2). During follow-up, 6 patients required subsequent surgery, most often secondary to pain and progressive deformity. One patient underwent elective below-knee amputation of the affected extremity. Of the remaining 11 patients, 7 of 11 reported continued pain and 8 of 11 maintained adequate range of motion at the ankle at the most recent follow-up.

CONCLUSION

Clinical follow-up demonstrated deteriorating results in a large percentage of patients. The high rate of additional procedures and continued pain in the current series suggests that even as a salvage procedure, naviculectomy may not provide adequate results for patients.

LEVEL OF EVIDENCE

Level IV, case series.
