Systems:
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 1,2.
Pathology
It is a rare complication that can develop following a distal humeral fracture (e.g. supracondylar fractures, humeral condylar fractures) in childhood but can also develop with central physeal arrest 3.
Treatment and prognosis
Whilst initially presumed to be a benign condition, long-term follow-up suggests that patients with fishtail deformity are prone to 1,2:
- functional impairment
- ongoing pain
- development of early osteoarthrosis
