Poster 198: Puddle Slip Injury Resulting in a Complete Proximal Avulsion of the Semimembranosus Tendon in a Nonathlete: A Case Report

Abstract

usually occurring during contact sports. A wide range of clinical courses have been described, however, pain lasting longer than 24 hours is generally uncommon. The MSCSAC is a novel tool to predict chronic stinger syndrome. It is calculated by subtracting the sagittal diameter of the spinal cord from the disk level sagittal diameter of the spinal canal at the C3-6 levels and then averaging these values. A cutoff of Ͻ4.3 mm has been shown to predict a greater than 13-fold increase in risk of developing chronic stinger syndrome. The MSCSAC score of 3.2 mm correlated with the patient's history of multiple stingers. In discussing return to play, it was emphasized that he is at greater risk for future stinger injuries based on MSCSAC index. Conclusions: The MSCSAC is a novel, sensitive tool that may be used to predict chronic stinger syndrome.
