Treatment of ulna coronoid process fracture with mini-plate internal fixation through modified anterior approach of elbow joint

Abstract

Objective To investigate the curative effects of mini-plate internal fixation through modified anterior approach of elbow joint for the treatment of ulna coronoid process fracture. Methods From January 2013 to December 2015, 11 cases of ulna coronoid process fracture were treated by mini-plate internal fixation through modified anterior approach of elbow joint. The functional recovery of elbow joint was evaluated after the operation. Results All the patients were follow-up for 8 to 25 months with an average of 15.4 months. Bone healing was achieved in all the cases showed by X-ray. The range of motion was (115.00±8.56)° for elbow flexion and extension, (130.00±6.58)° for forearm rotation. According to Mayo Elbow Performance Score, the elbow function was rated as excellent in 6 cases, good in 4 cases, fair in 1 case. Mild heterotopic ossification occurred in 1 case. Lateral brachial cutaneous nerve injury occurred in 1 case. No infection, vascular injury, joint dislocation, traumatic arthritis and stiffness occurred. Conclusion In the treatment of ulna coronoid process fracture, elbow joint can be fully exposed by modified anterior approach and mini-plate internal fixation is reliable to achieve good clinical effect.
