Background:
Distal humeral malunions are uncommon injuries, often associated with limited elbow motion, pain, instability, weakness, and sometimes ulnar neuritis. The complex anatomy of the elbow joint makes this condition one of the most complex elbow injuries to treat.
Materials And Methods:
Four patients were treated by the same surgeon between 2011 and 2013 using a double-locking precontoured plating system for malunited intra-articular or extra-articular fractures of the distal end of the humerus.
Results:
At a mean 3 years of follow-up, a significant improvement in the elbow motion and functional outcome, evaluated with the Mayo Elbow Performance Index and the Disability of the Arm, Shoulder, and Hand, were observed. Articular reduction obtained after the surgery was maintained in all patients without evidence of avascular necrosis. No other complications (i.e., infection, nervous iatrogenic lesions) were reported.
Conclusions:
Corrective osteotomy using double-locking precontoured plating system preceded by preoperative planning using a CT scan allowed an improvement in the functional outcome and elbow motion, without complications.
