  • Effectiveness of improved elbow anteromedial approach in treatment of ulna coronoid process fracture

    Objective To observe the effectiveness of reduction and fixation by the improved elbow anteromedial approach in treatment of ulna coronoid process fracture. Methods Between January 2010 and December 2014, 13 patients with the ulna coronoid process fracture were treated with reduction and fixation by the improved elbow anteromedial approach. There were 10 males and 3 females with an average age of 37.2 years (range, 18-57 years). Five cases were caused by traffic accident, 7 cases by falling injury from height, and 1 case by object impact injury. Seven cases were the terrible triad of the elbow, 4 cases were the ulna coronoid process and radial head fractures, 1 case was the proximal radius and ulna fractures, and 1 case was the ulna coronoid process and distal radius fractures. According to Regan-Morrey classification criteria, the ulna coronoid process fracture was rated as type Ⅱ in 2 cases and as type Ⅲ in 11 cases. According to O’Driscoll classification criteria, 10 of the 13 cases were anterior coronoid fracture (8 cases of type Ⅱb, 2 of type Ⅱc), and 3 of basal fracture. The operation time, amount of intraoperative bleeding, postoperative complications, range of motion (ROM) of the elbow joint, Mayo elbow function index (MEPI) score and fracture healing time were recorded. Results The average operation time was 38.7 minutes (range, 30-55 minutes), and the average amount of intraoperative bleeding was 109.3 mL (range, 90-160 mL). All incisions healed at stage Ⅰ. There was no iatrogenic vascular or nerve injury. All patients were followed up 13-24 months (mean, 16.9 months). All fractures achieved clinical healing. The average healing time was 11.2 weeks (range, 8-16 weeks). There were 2 cases of heterotopic ossification. At last follow-up, the ROM of elbow flexion was 119-145° (mean, 132.4°); the ROM of elbow extension was –8-15° (mean, 7°). The ROM of forearm pronation was 68-90° (mean, 78.6°), and the ROM of forearm supination was 76-90° (mean, 84.3°). At last follow-up, the MEPI score was 70-100; and 9 cases were excellent, 3 cases were good, and 1 case was fair. The excellent and good rate was 92.3%. Conclusion Improved elbow anteromedial approach for the ulna coronoid process fracture can not only avoid the injuries of surrounding blood vessels and nerves, but also perform fracture reduction and fixation under direct vision. It is a safe, simple, and effective treatment method for the ulna coronoid process fracture.

  • Treatment of ulnar coronoid process fracture via a modified anteromedial approach

    ObjectiveTo investigate the effectiveness of a modified anteromedial approach in the treatment of ulnar coronoid process fracture.MethodsBetween February 2017 and July 2018, 15 patients with ulna coronoid process fracture were reviewed. There were 9 males and 6 females, with an average age of 42.3 years (range, 24-60 years). The causes of injury included falling in 10 cases and traffic accidents in 5 cases, all cases were closed injury. According to the O’Driscoll classification, there were 4 cases of type Ⅰ, 6 cases of type Ⅱ, and 5 cases of type Ⅲ. The time from injury to operation was 2-8 days (mean, 3.7 days). All fractures were treated via a modified anteromedial approach between the pronator teres and the flexor carpi radialis plus with partial incision of flexor tendon aponeurosis. The fracture healing, muscle strength of forearm, postoperative complications were observed. At last follow-up, the elbow mobility were measured, the function of elbow was evaluated by Mayo elbow performance score (MEPS).ResultsAll cases were followed up 10-18 months (mean, 13.3 months). Fracture union was achieved in all patients with a mean time of 10 weeks (range, 8-14 weeks). No obvious decrease of hand grip strength, nerve injury, and infection occurred. One patient had slight heterotopic ossification without special treatment. At last follow-up, all patients had stable elbows with good flexion-extension and varus-valgus stability, the mean flexion was 123.3° (range, 100°-140°), mean extension loss compared with that before operation was 6.7° (range, 0°-20°), mean pronation was 76.0° (range, 60°-85°), and mean supination was 75.8° (range, 55°-90°). The MEPS score was 65-100 (mean, 90.3) with the result of excellent in 10 cases, good in 4 cases, and fair in 1 case.ConclusionThe treatment of ulnar coronoid process fracture via the modified anteromedial approach provides excellent exposure, minimal invasion, fewer complications, and satisfactory prognosis, which is conducive to elbow joint function recovery.
