BackgroundAlthough mid-shaft clavicular fractures are generally thought to be non-serious injuries that nearly always heal with non-operative treatment, recent studies found non-union rates of 3%-7% in simple fractures and 20%-33% in complex fractures. The primary objective of this study was to report the functional and anatomical outcomes after screw-plate fixation of displaced mid-shaft clavicular fractures with three or more fragments.HypothesisScrew-plate fixation in this indication is an excellent treatment option that minimises the risk of complications.MethodsA search of our database from 6 January 2012 to 27 December 2016 identified 410 cases of clavicular fracture, of which 250 were managed surgically, including 172 meeting our inclusion criteria and having complete data. These 172 patients were managed using a curved pelvic reconstruction plate with 3.5-mm non-locking screws positioned over the antero-superior aspect of the clavicle. All 172 patients were re-evaluated at least 1 year after surgery by an independent assessor, who determined the UCLA score.ResultsWe studied 172 patients, 154 (89.5%) males and 18 females with a mean age of 34.5±14.5 years (range, 13-69 years). In 84.5% of cases, the fracture was a sports injury, and the most common sports were skiing (26%), cycling (21%), and mountain biking (18.5%). Of the 172 fractures, all but 1 healed, within a mean of 87 days (range, 45-120 days). After removal of the fixation material, 8 (4.5%) patients experienced a recurrent fracture, within a mean of 90 days (range, 2-210 days); 4 of these recurrent fractures were caused by high-energy traumas occurring 6 months after implant removal. The UCLA score determined at re-evaluation indicated that the outcome was excellent in 164 (95.5%), good in 5 (3%), and fair in 3 patients.ConclusionInternal fixation using a curved pelvic reconstruction plate fixed with 3.5-mm screws provides excellent functional and anatomical outcomes in patients who have displaced mid-shaft clavicular fractures with three or more fragments.Level Of EvidenceIV, retrospective cohort study.Copyright © 2019 Elsevier Masson SAS.
