Superior Shoulder Suspensory Complex Reconstruction For Acute And Chronic ACJ Dislocations Using Lars Artificial Ligament: Evaluating The Early Outcome Of A 3-Tunnel Technique

this study was 48.84% (42/86).The clavicular inter-tunnel ratio showed no statistically significant difference between both groups (8.76 AE 0.43% VS 8.3 AE 0.35%, p¼0.32).Neither conoid nor trapezoid ratio was different between both groups.However, the initial reduction degree was statistically significantly different between both groups (p¼<0.001).Over-reduction of clavicle could reduce the risk of radiographic failure (15.38%VS 34.29%).On the other hand, under-reduction could increase the risk (73.68%VS 34.29%).Conclusion Clavicular inter-tunnel ratio failed to show any association with radiographic failure at 6 months.However, the initial reduction degree greatly affected the radiographic outcome.Further work with more advanced imaging that could cover all of the potential factors is needed to specify the causes of radiographic failure after this operation.
