    CONTEXT AND OBJECTIVE: Shoulder dislocation is the most common dislocation among the large joints. The aim here was to compare the effectiveness of reduction of acute anterior shoulder dislocation with or without articular anesthesia. DESIGN AND SETTING: Prospective randomized trial conducted in Escola Paulista de Medicina, Universidade Federal de São Paulo (UNIFESP) (EPM-UNIFESP). METHODS: From March 2008 to December 2009, 42 patients with shoulder dislocation were recruited. Reductions using traction-countertraction for acute anterior shoulder dislocation with and without lidocaine articular anesthesia were compared. As the primary outcome, pain was assessed through application of a visual analogue scale before reduction, and one and five minutes after the reduction maneuver was performed. Complications were also assessed. RESULTS: Forty-two patients were included: 20 in the group without analgesia (control group) and 22 in the group that received intra-articular lidocaine injection. The group that received intra-articular lidocaine had a statistically greater decrease in pain over time than shown by the control group, both in the first minute (respectively: mean 2.1 (0 to 5.0), standard deviation, SD 1.3, versus mean 4.9 (2.0 to 7.0, SD 1.5; P < 0.001) and the fifth minute (respectively: mean 1.0; 0 to 3.0; SD = 1.0 versus mean 4.0; 1.0 to 6.0; SD = 1.4; P < 0.001). There was one failure in the control group. There were no other complications in either group. CONCLUSION: Reduction of anterior shoulder dislocation using intra-articular lidocaine injection is effective, since it is safe and diminishes the pain. CLINICAL TRIAL REGISTRATION: ISRCTN27127703.

    Shoulder rotator strength and torque steadiness in athletes with anterior shoulder instability or SLAP lesion
    (Elsevier B.V., 2014-09-01) Saccol, Michele Forgiarini; Zanca, Gisele Garcia; Ejnisman, Benno [UNIFESP]; Mello, Marco Tulio de [UNIFESP]; Mattiello, Stela Márcia; Universidade Federal de São Carlos (UFSCar); Universidade Federal de São Paulo (UNIFESP)
    Objectives: To investigate shoulder rotator strength and steadiness in athletes with anterior instability and superior labrum anterior posterior (SLAP) lesion.Design: Cross-sectional laboratory study.Methods: Athletes with anterior shoulder instability (instability group, n=10) and a SLAP lesion (SLAP group, n = 10) were compared with healthy athletes matched by age, anthropometrics and sport (control group for shoulder instability, n = 10 and control group for SLAP, n = 10). Torque steadiness was evaluated with three 10 s submaximal isometric contractions (35% of peak torque) with the arm at 900 of shoulder abduction and 900 of external rotation. the mean isometric torque, standard deviation and coefficient of variation were measured from the steadiness trials. To evaluate shoulder rotator strength, concentric isokinetic tests (90 degrees/s, 180 degrees/s) were performed at the 90-90 degrees position and peak torque to body mass and shoulder external to internal rotation ratio variables were analyzed. the variables were tested with the instability and control groups with respect to shoulder instability and between the SLAP and control groups for SLAP lesion using the Mann-Whitney test.Results: the SLAP group presented a higher coefficient of variation than the SLAP control group (p = 0.003). Regarding shoulder strength, the internal and external shoulder rotators were weaker in the instability group than in the instability control group (p <0.05).Conclusions: Athletes with anterior shoulder instability presented shoulder rotation weakness, while athletes with a SLAP lesion showed higher torque fluctuation during internal rotation. These results indicate that there are different alterations to strength and sensory motor control in each condition. (C) 2013 Sports Medicine Australia. Published by Elsevier B.V. All rights reserved.
