Isolated Cuboid-Lateral Cuneiform Coalition A Rare Cause of Foot Pain.

Tarsal coalitions represent a cohort of conditions characterized by bony, cartilaginous, or fibrous union of two or more tarsal bones. These disorders are often poorly understood by medical professionals, often leading to delays in diagnosis and treatment. They may be asymptomatic or cause hindfoot pain, stiffness, decreased range of motion, and foot deformities. Coalitions can be investigated by an ascending sequence of imaging including radiography, computed tomography, and magnetic resonance imaging. They may be managed conservatively with orthoses, activity modification, physiotherapy, anti-inflammatory medications, or definitive surgical intervention. To our knowledge, cuboid-lateral cuneiform coalition has not been reported in the orthopedic literature. We describe a 40-year-old woman with this condition who reported a 1-year history of left foot pain and stiffness. She was definitively diagnosed with magnetic resonance imaging and was managed conservatively with an aircast boot and hydrocortisone injection.
