Clinical Details

Clinical and radiological findings:  A 40-year-old left-handed male sustained a complex open elbow injury following a fall from height. The patient presented with no neurovascular deficits. Radiographs and CT scans revealed fractures of the proximal ulna and radius, along with ligamentous injuries. The injury was classified as AO/OTA 2R1B3 for the radius and 2U1B3 for the ulna.

Preoperative Plan

Planning remarks:  The preoperative plan included open reduction and internal fixation (ORIF) of the proximal ulna and radius, lateral collateral ligament (LCL) repair, and a medial approach for coronoid bone suture and medial collateral ligament (MCL) repair.

Surgical Discussion

Patient positioning:  The patient was positioned supine with the arm placed on a radiolucent hand table. A sterile tourniquet was applied to the upper arm.

Anatomical surgical approach:  A combined surgical approach was utilized: - For the ulna and radius ORIF, a posterior midline incision was made, extending from the olecranon to the proximal forearm. The triceps muscle was split longitudinally to expose the fracture sites. - For the LCL repair, a lateral approach was used, involving an incision over the lateral epicondyle with careful dissection to identify and repair the ligament. - For the coronoid bone suture and MCL repair, a medial approach was performed. An incision was made over the medial epicondyle, and subperiosteal dissection was carried out to expose the coronoid process and MCL.

Operative remarks: 

During the procedure, it was noted that restoring the ulnar length posed a significant challenge. Initially, the ulna was fixed first, followed by the radius. However, incongruence of the proximal radioulnar and elbow joints was observed. To address this, the ulnar fixation was revised by removing the distal screws and elongating it by one screw hole to achieve proper alignment. This step ensured congruency of both joints.

Very nicely done. What considerations would you have for placing graft in the ulnar defect?
