Iatrogenic Irreducible Pediatric Salter-Harris II Middle Phalanx Base Fracture With Dorsal Dislocation of the...

Pediatric phalangeal Salter-Harris (SH)-type fracture dislocations are rare injuries that often require open reduction and stabilization. We present a case of a 14-year-old male who sustained an iatrogenic irreducible SH II dorsal fracture dislocation of the small-finger proximal interphalangeal joint (PIPJ) after an attempted closed reduction of a small-finger PIPJ dislocation by a community emergency medicine physician. Following the reduction attempt, the epiphysis was noted on radiographs to be rotated approximately 90° with persistent dorsal dislocation and an associated SH II fracture of the base of the middle phalanx. The patient was sent to our trauma center for further evaluation by our on-call hand surgeon and required open reduction and pinning of the fracture dislocation. To our knowledge, this pattern of iatrogenic PIPJ fracture dislocation has not been previously described in the literature. We outline the case presentation, treatment method, and learning points for both the on-call hand surgeon as well as the community emergency medicine physicians in this report.
