Surgical resection of calcaneo-navicular coalition (CNC) with
interposition of fat or muscle graft is indicated when there is failure of
conservative treatment. OBJECTIVES: to evaluate the clinical and functional of
outcome of a new mini-invasive technique for resection of CNC and interposition
of synthetic graft. METHODS: This is a prospective case series study on 9
patients (12feet) with symptomatic CNC. Percutaneous resection of the CNC was
done using a motorized bone burr through a small incision in the sinus tarsi
under image intensifier control. After complete resection a synthetic graft of
Teflon or Dacron measuring 15mmx30mm was interposed to prevent re-union of the
bone bar. RESULTS: The mean follow up period was 26.44 months (+/-1.5 SD). There
was statistically significant improvement in the mean total AOFAS score from
47.89 (+/-8.49 SD) preoperatively to 90.22 (+/- 5.26 SD) at two years follow up
(P<0.05). The mean time to return to full daily activity was 7.44 weeks (+/-0.88
SD) CONCLUSION: Percutaneous resection of calcaneo-navicular bar with
interposition of synthetic graft is an effective mini-invasive method for
treatment of calcaneo-navicular coalition with good results in 44.4% of patients
and excellent results in 55.6% of patients.
