Case:
Closed injury of the proximal interphalangeal joint (PIPJ), where the dorsally displaced epiphysis is lying on the dorsum of PIPJ, is sometimes called a jockeyed epiphyseal fracture (radiographs give an impression jockey sitting on a horse). We describe its variation in a 7-year-old boy who had a dorsally displaced epiphyseal fracture of the middle phalanx accompanied by fracture of the proximal phalanx. He was treated with open reduction and relocation of the epiphysis. For the first 3 months of follow-up, the patient obtained reasonable movement of PIPJ which gradual deteriorated over 1 year.
Conclusion:
This unusual injury with its sequelae (avascular necrosis of the proximal phalanx condyle) is reported in this article.
