Experimental model in cadavera of arthroscopic resection of calcaneonavicular coalition and its first in-vivo application: preliminary communication

Abstract

Open surgical resection of calcaneonavicular coalition is indicated after the failure of conservative treatment. Our objectives are to develop the arthroscopic surgical technique and to check the feasibility of the arthroscopic resection of the calcaneonavicular coalition. We designed and performed endoscopic resection of the calcaneonavicular ligament and part of the anterior process of calcaneus as a simulation of the coalition resection on four cadaver specimens. After this procedure, we successfully performed the first resection in a 12-year-old girl, without any soft tissue interposition. American Orthopaedic Foot and Ankle Society Hindfoot Scale was 55 before surgery, 98 after 10 weeks, and 100 after 2 years without recurrence.
