Iselin’ Disease - Apophysitis of the Fifth Metatarsal Base: Report of Two Cases

Iselin’ disease is a benign adolescent growth disturbance of the base of the fifth metatarsal called epiphysitis or apophysitis by others caused by abnormal traction of peroneus brevis tendon. This abnormality is rarely reported in medical literature, probably due to the benign nature and spontaneous healing in almost all cases. The affection should be known to medical specialist like orthopedists, radiologists, physical therapists and pediatricians. The differential diagnosis is made with Jones’ fracture of the fifth metatarsal and os vesalianum which is a congenital anomaly. We present two our cases with their similarities in clinical findings, typical radiologic images and complete relief from symptoms with conservative treatment
