  • TREATMENT OF ULNAR CORONOID PROCESS FRACTURE WITH MINI-PLATE

    Objective To investigate the treatment of ulnar coronoid process fracture with mini-plate and to evaluate the cl inical results. Methods Between September 2006 and March 2009, 14 patients with ulnar coronoid process fracture were treated with open reduction and internal fixation of mini-plate. There were 10 males and 4 females with an average age of 29 years (range, 14-51 years). Fracture was caused by fall ing from height in 4 cases and traffic accident in 10cases. The locations were left side in 6 cases and right side in 8 cases. According to Regan-Morrey classification, there were 2 cases of type I, 6 of type II, and 6 of type III. The flexion-extension arc of the elbow was (60 ± 10)° and the forearm rotation was (70 ± 10)°. The disease duration was 30 minutes to 11 days, and CT scan was used for definite diagnosis. Patients received early functional exercise 1 week postoperatively. Results All incisions healed by first intention. Fourteen cases were followed up 12-25 months (17 months on average). All fractures healed well, and the average union time was 10 weeks with a range of 7-12 weeks. No 1oosening or breakage of the internal fixation occurred except for 2 patients who had heterotopic ossification. The flexion-extension arc of the elbow was (110 ± 10)° and the forearm rotation was (130 ± 15)°, showing significant difference when compared with that before operation (P lt; 0.05). The cl inical results were evaluated according to Morrey’s scale, 8 cases were rated as excellent, 4 as good, and 2 as fair; the excellent and good rate was 85.7%.

    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.

    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.

    ObjectiveTo explore the effectivenesss of simple lateral extensor digitorum communis (EDC) split approach combined with loop-plate fixation in the treatment of ulnar coronoid fracture in terrible triad of elbow (TTE).MethodsThe clinical data of 60 patients with TTE who met the selection criteria between January 2015 and May 2018 were retrospectively analyzed. There were 48 males and 12 females, aged from 18 to 60 years (mean, 37.4 years). All the patients were closed fractures. Injury causes included fall injury in 28 cases, falling from height in 20 cases, and traffic accident injury in 12 cases. All patients had no vascular and nerve injury, and the time from injury to operation was 1-14 days, with an average of 4.8 days. The height and size of the fracture of the coronal process were measured by CT and accurate classifications were made. All the 60 patients were treated with simple lateral EDC split approach combined with loop-plate to fix the ulnar coronoid fracture; 20 patients of radial head fracture were fixed with hollow screw, 32 patients with mini-plate fixation, 8 patients with radial head prosthesis replacement; 16 patients with suture and 44 patients with suture anchor to reconstruct lateral collateral ligament complex; 10 patients with residual instability of elbow joint were fixed with hinge external fixator, and others were fixed with adjustable tension brace after operation. Postoperative imaging examination was performed to evaluate fracture healing and complications, such as loosening or breakage of internal fixator, osteoarthritis, and heterotopic ossification, etc. During follow-up, the range of motion (ROM) of the elbow joint was recorded, including elbow flexion, extension, and forearm pronation, supination. Mayo elbow function score system (MEPS) was used to evaluate elbow joint function at last follow-up.ResultsAll patients were followed up 16-24 months (mean, 20.2 months). All incisions healed by first intention after operation, and no complications such as vascular nerve injury, elbow joint instability, internal fixation failure, and infection occurred; the fracture healing time was 9-17 weeks (mean, 11.7 weeks). Four cases developed elbow stiffness after operation, and all underwent elbow joint lysis with internal fixator removal within 12-15 months after operation; 10 cases developed heterotopic ossification without special treatment. At last follow-up, the ROM of elbow flexion ranged from 85° to 135° (mean, 116°), the ROM of elbow extension ranged from 0° to 20° (mean, 11°), the ROM of forearm pronation ranged from 55° to 75° (mean, 70°), and the ROM of forearm supination ranged from 60° to 90° (mean, 83°). The MEPS score ranged from 55 to 100 (mean, 86.1); the effectiveness were excellent in 40 patients, good in 10 patients, fair in 6 patients, and poor in 4 patients, with an excellent and good rate of 83.3%.ConclusionThe simple lateral EDC split approach is fully exposed, and the loop-plate can fix the ulnar coronoid fractures firmly and stably, which can restore the stability of the elbow joint, and the effectiveness is satisfactory.
