IntroductionWhether displaced lateral clavicle fractures should be treated surgically remains controversial. This study aims to compare outcomes after surgical versus non-surgical treatment of such fractures.Patients And Methods113 patients with lateral clavicle fractures registered in the Swedish Fracture Register (SFR) during 2018 and with complete displacement on radiography were included in this cohort study. Linkage with the National Patient Register provided information on baseline medical comorbidities and further interventions. Patient-reported outcome measures (PROM) were assessed using the European Quality of Life Scale (EQ-5D-3L), the Short Musculoskeletal Function Assessment (SMFA), and the Quick Disabilities of the Arm, Shoulder and Hand (QDASH). The primary outcome was the total number of initial and delayed surgical procedures. The secondary outcome was difference in PROM between surgically and non-surgically treated patient groups.ResultsAt a mean follow-up of 4.4 (range 3.9-4.9) years, 35 (67 %) of the 52 patients initially treated surgically had undergone a secondary procedure, mostly for implant removal. Of the 61 initially non-surgically treated patients, 3 (5 %) underwent delayed surgical treatment due to non- or malunion. 45 (40 %) patients responded to follow-up questionnaires, but no statistically significant differences were found in any PROM between groups.ConclusionsTwo thirds of surgically treated patients with displaced lateral clavicle fractures underwent two procedures. The need for delayed surgical treatment in non-surgically treated patients was low and PROM was similar in both treatment groups. Nonsurgical treatment should be considered as an option to surgery for fully displaced lateral fractures of the clavicle more often.Copyright © 2024 The Authors. Published by Elsevier Ltd..
