Diaphyseal Fracture of both Bone Forearm with Distal Radio-Ulnar Joint Dislocation: An Unusual Entity

Introduction: Diaphyseal fractures of both radius and ulna are a common entity. The indirect forces which can lead to diaphyseal fracture of radius and ulna are also responsible for injuring distal radio-ulnar joint (DRUJ). However, simultaneous occurrence of fractures of both forearm bones, along with DRUJ disruption, is an uncommon entity.
Case report:
We came across a patient, who sustained fractures of both forearm bones with DRUJ dislocation. He was treated with open reduction and internal fixation of both the forearm fractures. His DRUJ reduced spontaneously after anatomical reduction of both fractures and was found to be stable on intra-operative assessment. He was immobilized in long arm splint for healing of DRUJ for 4 weeks. The fracture healed and the patient attained full range of motion at 12 weeks follow up.
Distal and proximal joints should be thoroughly examined in all the forearm fractures. Anatomical reduction of forearm bones is essential to obtain congruent DRUJ. Any instability of DRUJ should be assessed intra-operatively and dealt with accordingly for favorable functional outcome.
