The role of ultrasonography in the assessment of ulnar collateral ligament injury of the thumb - a diagnostic test accuracy meta-analysis. J Plast Surg Hand Surg. 2020 Nov 06;:1-13 Authors: Raheman FJ, Rojoa DM, Dhingra M, Siddiqui S, Macdonald CR Abstract The accurate diagnosis of ulnar collateral ligament (UCL) injuries of the thumb is important in identifying patients requiring surgery. Stener lesion, the most severe form of such injuries, is debilitating and leads to chronic instability if misdiagnosed. We evaluated the diagnostic accuracy of ultrasonography (USS) in UCL injuries. A systematic review of existing literature was performed with a meta-analysis using a bivariate mixed-effects model to estimate summary sensitivity and specificity. All observational studies were assessed, with participants of any age, who sustained UCL injuries of the thumb. A hierarchical model was used to generate a hierarchical summary receiver operating characteristic (HSROC) curves. We identified 17 studies reporting a total of 593 UCL injuries. Pooled estimates for sensitivity and specificity were 0.96 (95% CI 0.89-0.99) and 0.90 (95% CI 0.81-0.94), respectively for the diagnosis of Stener lesions; 0.81 (95% CI 0.66-0.93) and 0.87 (95% CI 0.67-0.96), respectively for non-displaced complete ruptures and 0.82 (95% CI 0.66-0.92) and 0.94 (95% CI 0.85-0.98), respectively for complete ruptures without Stener lesion. The area under the curve (AUC) for ...
