Résumé / Abstract
Purpose: The purpose of this report is to present a new provocative maneuver, the passive distraction test (PDT), as an examination tool to be used in the evaluation of patients thought to have a SLAP lesion and to compare its accuracy, precision, and reproducibility alone and in conjunction with previously published maneuvers. Methods: A retrospective analysis of 319 consecutive arthroscopies performed between May 2001 and November 2003 was performed. A total of 65 cases were excluded, 53 because of limitation of elevation to less than 150° or pain in the starting test position and 12 who had previous shoulder procedures performed by the senior author, leaving 254 cases for review. A thorough history was obtained and a thorough physical examination performed with a focus on the involved shoulder including specific provocative maneuvers for the clinical diagnosis of a SLAP lesion. The active compression test, the anterior slide test, and the PDT were used to clinically diagnose a SLAP lesion. The results from the 3 provocative maneuvers were compared with the arthroscopic findings to determine the sensitivity, specificity, negative predictive value (NPV), and positive predictive value of each test alone and in a logical combination. Results: Of 254 shoulder arthroscopies, 61 had a clinically significant SLAP lesion, for an incidence of 24%. The sensitivity and specificity for the PDT were 53% and 94%, respectively, with an NPV of 87% and positive predictive value of 72%. In combination, the PDT and the active compression test yielded an NPV of 90.5%. Conclusions: The PDT can be used alone or in combination to aid in the clinical evaluation and diagnosis of a SLAP lesion.
