title: Subtalar coalition: a case report.
abstract: Subtalar coalition is an uncommon condition that usually manifests in early adolescence(1). Frequently, this condition is missed. Delayed diagnosis may result in osteoarthritis requiring triple arthrodesis. Here, we report two patients with subtalar coalition. The first patient is a 12 year old boy who presented with right ankle pain for one year and was treated with excision of the coalition and bone wax insertion at the excision site. We followed up the patient for two years and the result was excellent with full range of movement of his right ankle and subtalar joint attained within two months. He returned to athletic activity by six months and was discharged with no complications after two years. The second patient is a 15 year old girl who presented with bilateral ankle pain and swelling for three years and was treated with excision of the coalition and subtalar interpositional arthroplasty bilaterally. She defaulted follow up after seven months as she was very satisfied with the result. We wish to highlight this condition which may be misdiagnosed as flexible flat foot or ankle sprain.
