RESUMO
Objective To evaluate the correlation of the glenoid track and glenoidal bone loss with the recurrence dislocation rate and the Rowe score. Methods Retrospective study that assessed the glenoid track and glenoidal bone loss through preoperative magnetic resonance imaging. Patients undergoing primary arthroscopic repair of anterior Bankart were included. Patients with glenoidal bone loss greater than 21%, rotator cuff tear, scapular waist fracture, and posterior or multidirectional instability were not included. Rowe score were the primary outcome, and the recurrence rate was the secondary outcome. Results One hundred and two patients were included. Postoperative recurrent instability was reported by 8 patients (7.8%). Four patients (50%) in the group with recurrence presented glenoidal bone loss greater than 13.5% against 24 (25.5%) in the group without recurrence ( p = 0.210), with a negative predictive value of 94.6%. Three patients (37.5%) in the recurrence group were considered off-track, against 13 (13.8%) in the group without recurrence ( p = 0.109), with a negative predictive value of 94.2%. Patients with absolute glenoid track value ≤ 1.5 mm had worse results in relation to the recurrence group, with 6 patients (75%) presenting recurrence ( p = 0.003). Conclusion Off-track injury and glenoidal bone loss greater than the subcritical are not related to the recurrence rate and Rowe score, despite the high negative predictive value. The cut of the absolute value of the glenoid track at 1.5 mm had a significant relationship with the recurrence rate.

Resumo Objetivo Avaliar a correlação do conceito de glenoid track e da perda óssea da cavidade glenoidal com a taxa de recidiva de luxação e pontuação na escala de Rowe. Métodos Estudo retrospectivo que aferiu o glenoid track e a perda óssea da cavidade glenoidal por ressonância magnética pré-operatória. Foram incluídos pacientes submetidos a reparo artroscópico primário de Bankart anterior. Não foram incluídos pacientes com perda óssea da cavidade glenoidal maior que 21%, rotura do manguito rotador, fratura de cintura escapular, instabilidade posterior ou multidirecional. A pontuação pela escala de Rowe foi o desfecho primário, e a taxa de recidiva foi o desfecho secundário. Resultados Cento e dois pacientes foram incluídos. A recidiva foi relatada por 8 pacientes (7,8%). Quatro pacientes (50%) do grupo com recidiva apresentaram lesão da cavidade glenoidal maior que 13,5% contra 24 (25,5%) do grupo sem recidiva (p= 0,210), com valor preditivo negativo de 94,6%. Três pacientes (37,5%) do grupo com recidiva foram considerados off-track, contra 13 (13,8%) do grupo sem recidiva (p= 0,109), com valor preditivo negativo de 94,2%. Pacientes com valor absoluto do glenoid track menor ou igual a 1,5 mm tiveram piores resultados em relação ao grupo com recidiva, sendo que 6 pacientes (75%) apresentaram recidiva (p= 0,003). Conclusão Lesão off-track e perda óssea da cavidade glenoidal maior que a subcrítica não apresentam relação significativa com a taxa de recidiva e a pontuação de Rowe, apesar do alto valor preditivo negativo. O corte do valor absoluto do glenoid track em 1,5 mm apresentou relação significativa com a taxa de recidiva.

RESUMO
OBJECTIVE: To evaluate the functional outcome of the remplissage technique, the healing of the capsulotenodesis of the infraspinatus tendon in Hill-Sachs lesion, and the degree of fatty infiltration of the infraspinatus muscle and its postoperative strength. METHODS: Twenty-five patients with recurrent anterior dislocation of the shoulder and Hill-Sachs lesion with a Hardy index > 20% who underwent the remplissage arthroscopic technique were evaluated with a minimum follow-up of 1 year. Patients underwent a clinical evaluation (Carter-Rowe and Walch-Duplay functional scores, measurement of range of motion and strength) and a magnetic resonance imaging (MRI) exam on the operated shoulder. RESULTS: Eighty-eight percent and 92% of the patients had good or excellent scores in the functional assessments of the Carter-Rowe and Walch-Duplay scores, respectively. A mean difference of - 1 kg in the strength of the operated limb was observed when compared with the contralateral limb ( p < 0.001), as well as a mean difference of 10° in external rotation 1 and 2 ( p < 0.001), also compared with the contralateral side. All of the patients who underwent an MRI exam presented high-grade filling of the Hill-Sachs lesion by capsulotenodesis, as well as absence of or minimal fatty infiltration in the infraspinatus muscle. CONCLUSION: The remplissage technique had good/excellent functional score results, despite the discrete, albeit statistically significant, loss of strength and of external rotation amplitude. Successful capsulotenodesis healing and filling of the Hill-Sachs defect were demonstrated.
RESUMO
BACKGROUND: The glenohumeral joint is characterized by its large degree of movement and consequently is the most susceptible joint to dislocations. There are few studies on the first episode of a shoulder dislocation in younger athletes. PURPOSE: To report the results of arthroscopic treatment for the first episode of a glenohumeral dislocation in younger athletes. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: In this retrospective study, 53 patients younger than 40 years (N = 54 shoulders) sustained their first anterior shoulder dislocation and underwent arthroscopic surgery. Surgery was undertaken in the lateral decubitus position. Standard posterior, anteroinferior, and anterosuperior portals were used, and the number of anchors and the degree of capsular plication were individualized and based on the arthroscopic findings of each patient. The minimum follow-up was 2 years (mean, 2.31 years), and patients were evaluated with the Rowe functional score, Athletic Shoulder Outcome Rating Scale (EROE; acronym in Portuguese), and visual analog scale (VAS) for pain. RESULTS: The mean EROE score was 93.8, with 98% of results being good or excellent, and the mean Rowe score was 95.0, with 98% good or excellent results. The mean VAS pain score was <1.0. The rate of recurrence of dislocations was 2%. The return-to-sports rate was 83%; patients with associated superior labral anterior-posterior (SLAP) lesions had a lower return-to-sports rate (P = .001) and lower EROE (P = .017) and Rowe (P = .019) scores. CONCLUSION: The present study showed favorable results for arthroscopic surgical treatment after the first dislocation episode in young athletes. It was an effective and safe treatment option in this population.

Resumo Objetivos Avaliar o resultado funcional da técnica de remplissage, a cicatrização da capsulotenodese do tendão infraespinal no defeito de Hill-Sachs, o grau de infiltração gordurosa do músculo infraespinal e sua força de rotação lateral no pós-operatório. Método Foram avaliados 25 pacientes comluxação anterior recidivante do ombro e lesão de Hill-Sachs comíndice de Hardy maior do que 20%, submetidos à técnica artroscópica de remplissage com seguimento mínimo de um ano. Os pacientes foram submetidos a avaliação clínica (escores funcionais deCarter-RoweeWalch-Duplay,medição de amplitude de movimento e força) e exame de ressonância magnética no ombro operado. Resultados Dos pacientes, 88% e 92% apresentaram resultados bons ou excelentes nas avaliações funcionais pelos escores de Carter-Rowe e Walch-Duplay, respectivamente. Identificou-se diferença média de 1 kg a menos de força do membro operado em relação ao contralateral (p < 0,001) e diferença média de 10° em rotação lateral 1 e 2 (p < 0,001), novamente com o uso como referência do lado contralateral. Todos os pacientes submetidos a ressonância magnética apresentaram preenchimento de alto grau da lesão de Hill-Sachs pela capsulotenodese, assim como ausência ou mínima infiltração gordurosa no músculo infraespinal. Conclusão A técnica de remplissage apresentou resultados bons/excelentes nos escores funcionais, apesar da perda discreta de força e amplitude de rotação lateral com significância estatística. Foram observados resultados excelentes quanto à cicatrização da capsulotenodese e ao preenchimento do defeito de Hill-Sachs.
