The arthroscopy direct fixation of the labrum the glenoid in order to correct the Bankart lesion in shoulder recurrent dislocation has lost its importance due to the high level of recurrence of the affection as well as implant loosening. OBJECTIVE: To show the efficacy of the direct fixation of the labrum to the glenoid in Bankart lesion. METHODS: 20 shoulders of 10 cadavers were dissected and Bankart lesions were produced in all specimens. The direct fixation was performed in 10 of the specimens using screws especially designed for this purpose and indirect fixation in the 10 contralateral shoulders by means of mini-anchors and labrum suturing. The specimens were submitted to traction until failure of the system en high-accuracy equipments. RESULTS: Both methods of fixation beared 234N forces of traction on average without loosening or breakage of the implants. Instead, we observed capsuloligamentary lesions. CONCLUSION: The direct fixation and the indirect fixation techniques present similar efficacy.
