Abstract: Introduction: Midshaft clavicular fractures are common amongst young adults. Conservative or surgical treatment for definitive fracture management has been widely debate, both with their pros and cons. Previous meta-analyses compared the clinical outcomes between conservative and surgical treatment options of midshaft clavicular fractures but failed to elucidate any difference in functional improvement. We postulate that functional improvement after fracture union plateaus and the clinical outcome after treatment varies at different time points. This meta-analysis will focus on the synthesis comparison of outcomes at early, short-term results (3 months), intermediate-term (6 to 12 months) and long-term (>24 months) clinical outcomes. Methods: A systematic search was done on databases (Pubmed, Embase, Medline, Cochrane) in June 2021. Search keywords were: midshaft clavicular fractures and clinical trials. Clinical trials fulfilling the inclusion criteria were selected for comparison and the clinical outcomes of midshaft clavicular fractures using surgical and non-surgical interventions in terms of improvement in the Disabilities of the Arm, Shoulder and Hand (DASH) score, Constant-Murley Score (CMS), time to union and risk ratio of treatment related complications were analysed in correlation with post-treatment timeframe. Results: Of the 3094 patients of mean age 36.7 years in the 31 selected studies, surgical intervention was associated with improved DASH score (standard-mean difference SMD -0.22, 95% CI -0.36 to -0.07, p = 0.003; mean difference MD -1.72, 95% CI -2.93 to -0.51, p = 0.005), CMS (SMD 0.44, 95% CI 0.17–0.72, p = 0.001; MD 3.64, 95% CI 1.09 to 6.19, p = 0.005), time to union (non-adjusted SMD -2.83, 95% CI -4.59 to -1.07, p = 0.002; adjusted SMD -0.69, 95% CI -0.97 to -0.41, p 24 months SMD -4.24, 95% CI -7.03 to -1.45, p = 0.003) and CMS (>24 months, SMD 1.03, 95% CI 0.39 to 1.68, p = 0.002; MD 5.77, 95% CI 1.63 to 9.91, p = 0.006). Surgical outcome is independent of fixation with plates or intra-medullary nails. Conclusion: Surgical intervention was associated with better clinical outcomes compared with non-surgical approach for midshaft clavicular fractures in terms of improvement in functional scores DASH, CMS, time to union and fracture related complications, although not to the minimal clinically significant difference. Benefits in the long-term functional improvements are more pronounced.
