Bone fractures and treatments

Double-plate fixation is a popular treatment method for intercondylar humeral fractures. Ulnar nerve complications are emphasized, but radial nerve complications are rarely mentioned. We present a case of iatrogenic radial nerve palsy following open reduction and double plating of a supracondylar/intercondylar fracture of the humerus. Before surgery, only a sensory deficit in the radial nerve territory was present, but after surgery, there was a complete motor deficit of the wrist and finger extensors. On exploration, a segment of nerve was found crushed within the reduced lateral condyle fracture site, with a screw from the posteroradial plate going through the nerve. Although rare, radial nerve injury can occur with posteriorly displaced supracondylar/intercondylar humerus fractures. When preoperative signs of radial nerve injury are present, we recommend that the radial nerve be identified and protected during double-plate fixation.
