Case:
A 23-year-old man presented with a right upper limb injury after a 10-m fall. Initial evaluation demonstrated a terrible triad elbow injury associated with a trans-scaphoid perilunate dislocation. Elbow stabilization with radial head replacement and carpal fixation was performed. Radiographs on postoperative day 7 demonstrated an ipsilateral Essex-Lopresti injury, which had been initially missed, and revision surgery was performed to reconstruct the interosseous membrane.
Conclusion:
Surgeons should maintain a high degree of suspicion for an ipsilateral Essex-Lopresti injury in patients with a terrible triad elbow fracture-dislocation in combination with a trans-scaphoid perilunate dislocation. Both preoperative imaging, including the contralateral side, and intraoperative evaluation are recommended to rule out longitudinal instability of the forearm in the setting of combined wrist and elbow fracture-dislocations.
