DESIGN: Multicenter retrospective study. SETTING: Five level I and II trauma centers. PATIENTS: Forty-four patients, average age 38.4 years (18-66 years), with a Neer type II lateral clavicle fracture treated with the clavicle hook plate between January 1, 2003, and December 31, 2006. INTERVENTION: Open reduction and internal fixation with the clavicle hook plate. Removal of all 44 implants after consolidation at a mean of 8.4 months (2-33 months) postoperatively. MAIN OUTCOME MEASUREMENTS: At an average follow-up of 27.4 months (13-48 months), functional outcome was assessed with the Constant-Murley scoring system. Radiographs were taken to evaluate consolidation and to determine the distance between the coracoid process and the clavicle. RESULTS: The average Constant score was 92.4 (74-100). The average distance between the coracoid process and the clavicle was 9.8 mm (7.3-14.8 mm) compared with 9.4 mm (6.9-14.3 mm) on the contralateral nonoperative side. We observed 1 dislocation of an implant (2.2%), 2 cases of pseudarthrosis (4.5%), 2 superficial wound infections (4.5%), 2 patients with hypertrophic scar tissue (4.5%), and 3 times an acromial osteolysis (6.8%). Thirty patients (68%) reported discomfort due to the implant. These implant-related complaints and the acromial osteolysis disappeared after removal of the hook plate. With all the patients, direct functional aftercare was possible. CONCLUSIONS: The clavicle hook plate is a suitable implant for Neer type II clavicle fractures. The advantage of this osteosynthesis is the possibility of immediate functional aftercare. We observed a high percentage of discomfort due to the implant; therefore, we advise to remove the implant as soon as consolidation has taken place.
