Answer B) Fracture distal humerus
- Fishtail deformity of the elbow is characterized by a contour abnormality of the distal humerus, which develops when the lateral trochlear ossification centers fail to develop or resorbs.
- It is an uncommon complication usually following a distal humeral fracture in childhood. Whilst initially presumed to be a benign condition, long-term follow-up suggests that patients with fishtail deformity are prone to:
- functional impairment
- ongoing pain
- development of early osteoarthrosis
