Synchronous fibrous tarsal coalition of the posterior subtalar joint and between the medial cuneiform and navicular in the same foot: An unusual case report and literature review

Abstract

Tarsal coalition (TC) is a well-known abnormality of the foot articulations due to failure of embryonic mesenchymal segmentation presenting with pain or deformity in orthopedic clinics. However, simultaneous TC affecting separate tarsal joints in the same foot is rare. We report a rare case of synchronous fibrous TC of the posterior subtalar joint and between the medial cuneiform and navicular bone of the right foot in a 25-year-old male and review the literature exploring such a combination. The clinical presentation and radiological findings leading to effective diagnosis and management are highlighted.
