Distal humerus fractures in adults are very difficult and challenging to treat due to intra articular and inter condylar involvement. It accounts for 2% to 6% of all fractures and one third of humerus fractures. The aim of this study was to evaluate the functional outcome of distal humerus fractures treated by bi columnar plating.
Materials and Methods: Our study consists of 30 post traumatic distal humerus fracture AO type C3 operated between December 2017 and December 2018. The functional outcome was assessed using The Mayo Elbow Performance Score. Patients were followed up at 6 weeks, 3months, 6months and 1 year post operatively.
Results: There were 21(70.0%) male patients, and 9(30%) female patients. Average age of the patients was 39.68 years with age ranging from 18 years to 80 years. 11(36.7%) cases were right humerus and 19(63.3%) were left sided humerus involved. All cases were operated through trans olecranon approach and chevron osteotomy technique, fracture stabilized with bi columnar locking compression plates. At the final follow up most of the patients had excellent postoperative elbow flexion with average arc of elbow flexion of 117.33 degrees, average extension deficit of 8.67 degrees, average pronation of 70.83 degrees, average supination of 70.83 degrees.
Conclusions: Bi columnar locking compression plates offer a good fixation for the distal humerus fractures with particular advantage in intra-articular type C3. The device helps in early mobilisation even in fractures with comminution due to its enhanced stability.
