EVALUATION OF SCAPULAR DYSKINESIA IN PATIENTS THAT UNDERWENT A LATARJET PROCEDURE.

Abstract

ABSTRACTObjective: To quantitatively assess the scapular movement of patients who underwent Latarjet surgery and to identify if they present scapular dyskinesia (SD), as well as correlate with the clinic state and the elevation degree of the shoulder.Methods: A cross-sectional study was carried out at the Movement Analysis Laboratory (LAM), at the Institute of Physical Activity and Sport Sciences, that quantitatively evaluated, using spherical retroreflective markers, the scapular movements of the control group (10 volunteers) and 22 patients (23 operated shoulders) that had been submitted to Latarjet surgery, between 2011 and 2016, with at least one year postoperative. The results of the control group were used as a parameter of normality and compared to those of the operated group. Posterior inclination, superior rotation, and medial rotation of the scapula were evaluated at angles of 60°, 90°, and 120° of elevation, both in ascending and descending phases. The statistical analysis used was the multivariate variance (MANOVA), comparing the right and left sides of the control group and, subsequently, the control group with the postoperative group (p = 0.05 in all tests).Results: When comparing the mean of the results of the quantitative evaluation of the control group with the operated group, no statistically significant differences were found between the two groups and between the dominant and non-dominant sides of the control group. Conclusion: Latarjet surgery does not cause SD, although there are alterations in some plane of the scapular movements in the ascending and/or descending phase.
