We wanted to analyze and report on the radiologic and clinical results of prospective Hook plate fixation for unstable distal clavicle fractures after a minimum of 2 years follow up. MATERIALS AND METHODS: We followed up 17 out of 20 cases that underwent prospective Hook plate fixation from 2008 to 2009. We performed radiologic follow up at 2 weeks, 6 weeks, 3 months, 6 months, 18 months and 24 months postoperatively. The clinical results were evaluated at 12 months and 24 months postoperatively.
The mean period for bony fusion was 14.5 weeks and the plate was removed after an average of 20.2 weeks. The VAS pain scores were 0.7 and 0.8, the UCLA scores were 33.5 and 33.3, the ASES scores were 92.8 and 92.5, the Constant-Murley scores were 81.5 and 77.0, the KSS scores were 92.5 and 94.3 and the ranges of motion were 173.3degrees and 173.7degrees of flexion, 56.0degrees and 54.5degrees of external rotation, 62.3degrees and 63.5degrees of the internal rotation, 172.0degrees and 172.6degrees of abduction and 43.3degrees, and 42.9degrees of extension at 1 and 2 years follow-up, respectively. There was no statistically significant difference of clinical outcomes and the range of motion at 1 year and 2 year postoperatively (p>0.05). There was no other complication except 1 case of delayed union.
For Hook plate fixation at 2 years postoperatively, the complications will be decreased and excellent clinical results should occur.
