Follow-up of Patients With Talocalcaneal Coalitions

The objective of this study was to develop a new classification system based on the articular facets involved to cover all coalitions and guide operative planning.

Study Overview

• Status: Completed
• Conditions: Talocalcaneal Coalition
• Intervention / Treatment: Other: talocalcaneal coalition

Detailed Description

Patients were diagnosed with talocalcaneal coalition using a CT scan, between January 2009 and February 2021. We classified the coalition into four main types according to the shape and nature of the coalition: I, inferiorly overgrown talus or superiorly overgrown calcaneus; II, both talus and calcaneus overgrew; III, coalition with an accessory ossicle; (I-III types are non-osseous coalition) IV, complete osseous coalition. Then each type was further divided into three subtypes according to the articular facets involved. A, the coalition involving the anterior facets; M, the coalition involving the middle facets, and P, the coalition involving the posterior facets.
