Ulnar nerve injury associated with trampoline injuries

Objective: This study reports three cases of ulnar neuropathy after trampoline injuries in children. Methods: A chart review was performed on children who sustained an ulnar nerve injury from a trampoline accident. In all cases, surgical intervention was required. Results: Injuries included upper-extremity fractures in two cases and an upper-extremity laceration in one case. All cases required surgical exploration with internal neurolysis and ulnar nerve transposition. Nerve grafts were used in two cases and an additional nerve transfer was used in one case. All patients had return of intrinsic hand function and sensation after surgery. Conclusion: Children should be followed for evolution of ulnar nerve neuropathy after upper-extremity injury with consideration for electrical studies and surgical exploration if there is no improvement after 3 months.
