Background: Clavicle fractures are one of the commonest fractures with accounts of 3 % of all injuries. Lateral end clavicle fracture contributes 25% of clavicle fractures and out of that 10-52% is unstable which requires various surgical fixations for better functional outcome. The aim of our study is to find out functional outcome following surgical fixation with locking plates. Methods: It is the prospective study conducted at Shalinitai Meghe Hospital, Nagpur from June 2019 to April 2020 (11 months) in 66 patients admitted at our hospital for surgical management. Results: 66 patients aged from 18-40 years with a mean age group of 29 years with 44 patients were right-sided clavicle fractures. Meantime for trauma to surgery was 76 hours with a mean operative time of 60 min. The average time for bony union of fracture was noted to be around two and a half months. After 8 weeks and 24 weeks, the Mean DASH score was found to be 4.6 and 11.63, respectively. The functional results were Excellent in 24 (36.36%), Good in 40 (60.6%), Fair in 1 (1.51%), and Poor in 1 (1.51%) patients according to the DASH score. Conclusion: Though there are various surgical methods for fixing such unstable variety of lateral clavicle fracture, the gold standard treatment option is debatable and challenging. But we found in our study, the functional outcome after using a pre-contoured locking plate for such cases is beneficial and satisfactory.
