    ANTERIOR INSTABILITY OF THE SHOULDER. RETROSPECTIVE STUDY ON 159 CASES
    (2011) FERREIRA NETO, Arnaldo Amado; CAMANHO, Gilberto Luis; FELIX, Alessandro Monterroso; BENEGAS, Eduardo; BITAR, Alexandre Carneiro; RAMADAN, Lucas Busnardo; MALAVOLTA, Eduardo Angeli
    Objective: To analyze the results of 159 patients with anterior instability of the shoulder submitted to arthroscopic treatment from January 2001 to December 2005. Methods: Retrospective study of complete patient records. Results: In 108 patients the Bankart lesion was found, while in 62 patients, SLAP type lesions were found. An average of 2.7 anchors was used. 42 cases presented complications; 14 had pain on effort, 12 had some degree of reduction of external rotation, and 16 had recorrence. The patients who developed complications used an average of 2.5 anchors, while those without complications used an average of 2.8 anchors (p<0.05). Of the 35 patients with anterior glenoid bone lesion, 8 had recorrence, while of the 124 patients without fractures, 8 had recorrence (p<0.05). Of the 113 patients with first-time traumatic dislocations, 12 developed limitation of external rotation, while in 46 atraumatic cases none developed limitation (p<0.05). Of the patients with SLAP lesion, 11 developed pain, while in the cases without this lesion, only 3 presented pain (p<0.05). Conclusion: There were more recurrences (deveria ser plural e recurrences, nao recurrence) in cases of anterior glenoid bone lesion. Post-operative pain was more frequent when the lesion type was SLAP Limitation of external rotation is associated to traumatic instability.

    Reconstrução coracoclavicular com enxerto tendíneo na luxação acromioclavicular crônica
    (2011) ASSUNCAO, Jorge Henrique; FERREIRA NETO, Arnaldo Amado; BENEGAS, Eduardo; MALAVOLTA, Eduardo Angel; GRACITELLI, Mauro Emilio Conforto; SILVA, Fernando Brandao de Andrade e
    Objective: The aim of this study is to present the radiographic and functional results of patients undergoing treatment for chronic acromioclavicular dislocation with coracoclavicular ligament reconstruction using tendon graft. Method: Between 2007 and 2008, fifteen patients with chronic Rockwood type III through V acromioclavicular joint dislocations underwent reconstruction of the coracoclavicular ligaments using semitendinosus tendon graft. Two patients were excluded due to inadequate follow up. Thirteen patients were followed up clinically and radiographically after a mean of 16 months (range 12-26 months). Clinical evaluation was performed using the UCLA and Constant scores. Preoperative and postoperative radiographs were compared. Results: In this group of 13 patients followed up for at least one year, the Constant score ranged from 60.9 (26-88) in the preoperative evaluation to 87 (60-98) at the last evaluation during the postoperative period (p< .001). The mean UCLA score improved from 16.8 points (11-27) to 33 (29-35) points. (p=0.001). After 1 year of follow-up, the postoperative radiographic control showed twelve patients (92%) with equal coracoclavicular distance between the affected and unaffected shoulders. No anteroposterior translation in the axial view was present in any of the shoulders operated on. Conclusion: The functional and radiographic results were very satisfactory in patients undergoing reconstruction of chronic acromioclavicular dislocations, with a low recurrence rate. Level of Evidence: Level IV, case series.

    ARTHROSCOPIC TREATMENT OF ACUTE ACROMIOCLAVICULAR JOINT DISLOCATION USING SUTURE ANCHORS
    (2011) CAVINATTO, Leonardo Muntada; IWASHITA, Renato Akira; FERREIRA NETO, Arnaldo Amado; BENEGAS, Eduardo; MALAVOLTA, Eduardo Angeli; GRACITELLI, Mauro Emilio Conforto; SILVA, Fernando Brandao de Andrade e; ASSUNCAO, Jorge Henrique; HELITO, Paulo Victor Partezani
    Objective: To present the clinical and radiographic results of a case series of patients with acute acromioclavicular dislocation (MD) treated by arthroscopic coracoclavicular fixation with suture anchors. Method: Twenty patients with AAD with less than 30 days since the injury were submitted to a coracoclavicular stabilization procedure using 2 suture anchors placed at the base of the coracoid process. Each suture anchor was connected to 2 strands of No.2 nonabsorbable-braided sutures, which were passed through the holes drilled in the clavicle and tied to the upper surface of the clavicle. The coracoclavicular distance was measured and compared to the opposite side using radiographic evaluation. Constant and UCLA scores were used to determine clinical and functional evaluation after 6 months. Results: Of the initial twenty cases, six were submitted to a new surgical procedure and were excluded from the study. Of the fourteen patients remaining, only two maintained the initial reduction, while the remainder presented some degree of reduction loss. The Constant and UCLA score averages were 94.79 (82-100) and 32.64 (26-35) respectively. Conclusion: The technique had a high incidence of reduction loss after 6 months of follow up. The clinical and functional evaluation was satisfactory, with a high average score. Level of Evidence: Level III, retrospective study.
