Reparación sistemática del manguito rotador: Clasificación de la Fundación Santa Fe de Bogotá / Standardized rotator cuff repair. Classification of Fundación Santa Fe de Bogotá

La cirugía de manguito rotador se ha popularizado en los últimos años y pasó de realizarse mediante una técnica abierta, en la mayoría de los casos, a la reparación artroscópica. Se han descrito múltiples técnicas para la fijación del hueso, pero no se han estandarizado el orden y los pasos para llevar a cabo esta reparación, lo que generó inconsistencias y heterogeneidad en los resultados de la reparación. En este artículo, se propone una nueva clasificación de las lesiones del manguito rotador que les permitirá a los cirujanos tomar decisiones durante la cirugía de reparación artroscópica del manguito rotador. Nivel de Evidencia: IV

Rotator cuff surgery has become more popular in recent years, transitioning from an open technique to arthroscopic surgery. Although multiple techniques for bone fixation have been described, the steps to perform this repair have not been standardized, leading to inconsistencies and heterogeneity in the outcomes. This article proposes a new classification of rotator cuff injuries that will help surgeons make decisions during arthroscopic rotator cuff repair surgery. Level of Evidence: IV

Comparative Study between Multi-slice Computed Tomographic Arthrography and Arthroscopy in the Evaluation of Rotator Cuff Tears / Estudo comparativo entre artrotomografia computadorizada multi-slice e artroscopia na avaliação das lesões do manguito rotador

Abstract Objective To compare the imaging findings of anatomical alterations using multi-slice computed tomographic arthrography in the evaluation of rotator cuff tears in the shoulder, correlating them with the arthroscopy (the gold standard diagnostic test) findings. Materials and Methods A longitudinal, prospective, comparative study of diagnostic accuracy performed in the period between June 2016 and June 2017 in patients of both sexes, aged between 40 and 70 years, with shoulder rotator cuff tendon tears and therapeutic need to undergo shoulder arthroscopy. Patients with contraindication to magnetic resonance imaging were included. After multi-slice computed tomographic arthrography, all patients underwent arthroscopy. Results To obtain the results, the following parameters were determined: sensitivity, specificity, accuracy, positive predictive value, negative predictive value, and Kappa coefficient, and contrast between the imaging method and arthroscopy. Conclusion In the impossibility of performing magnetic resonance imaging (the gold standard imaging technique), multi-slice computed tomographic arthrography is an imaging examination capable of evaluating/diagnosing rotator cuff tears.

Resumo Objetivo Comparar os achados por imagem das alterações anatômicas da artrotomografia computadorizada multi-slice na avaliação das lesões do manguito rotador do ombro e correlacioná-los com os achados da artroscopia (exame diagnóstico padrão-ouro). Materiais e Métodos Estudo longitudinal, prospectivo, comparativo de acurácia diagnóstica, feito de junho de 2016 a junho de 2017, em pacientes de ambos os sexos, com idades entre 40 e 70 anos, com lesão dos tendões do manguito rotador do ombro, e que tinham necessidade terapêutica de fazer artroscopia do ombro. Foram incluídos pacientes com contraindicação à realização de ressonância magnética. Após a artrotomografia computadorizada multi-slice, todos os pacientes foram submetidos a artroscopia. Resultados Para a obtenção dos resultados, os seguintes parâmetros foram considerados: sensibilidade, especificidade, acurácia, valor preditivo positivo, valor preditivo negativo, coeficiente Kappa, e contraposição do método de imagem com a artroscopia. Conclusão Na impossibilidade da realização da ressonância magnética (exame de imagem padrão-ouro), a artrotomografia computadorizada multi-slice se mostra um exame de imagem capaz de avaliar/diagnosticar as lesões do manguito rotador.

Low prevalence of relevant associated articular lesions in patients with acute III-VI acromioclavicular joint injuries.

PURPOSE: To define the prevalence of associated articular injuries in patients with severe (Rockwood's III-VI) acute acromioclavicular joint injuries and to find out how many of these were associated with the traumatic event and required surgical treatment. METHODS: Retrospective observational multicentric study performed in ten centres included patients who required surgery for acute acromioclavicular joint injuries between 2010 and 2017. The inclusion criteria were: presence of an acute acromioclavicular joint injury (grades III-IV-V-VI) and surgical treatment within 3 weeks of injury that included a full arthroscopic evaluation of the shoulder. Basic epidemiological data, severity of the original injury, prelesional sport level and prelesional work site requirements were recorded. The presence of intraarticular glenohumeral lesions and information of their characteristics, treatment, and whether each lesion was considered acute or pre-existing was also recorded. RESULTS: Two-hundred one subjects [mean (SD) age 36.7 (11.7) years] with acute acromioclavicular joint injuries (110 Rockwood type III, 34 type IV, 56 type V and 1 type VI) fulfilled the inclusion criteria. A total of 28 (13.9%) associated articular lesions were found. These lesions were more often found in grade IV injuries (26.5% in grade IV vs 11.4% in grade III, p = 0.037) and presented in males (18.7% in males vs 4% in females, p = 0.015). Age, laterality, sport level or work requirements did not affect the prevalence of associated lesions. Twelve were rotator cuff tears (6 PASTA lesions, 3 partial supscapularis tears, 2 bursal supraspinatus tears and 1 full-thickness supraspinatus tear), 16 were labral tears (9 anterior, 1 posteroinferior and 6 SLAP). Only 14 (50% of lesions, 7% of total subjects) were considered acute and all but one (an SLAP type 2 tear) required further surgical attention. Most pre-existing lesions were left untreated (n = 7) or managed with minimal debridement (n = 6), and only two required further surgery. The prevalence of associated lesions that required surgical management was 7.46%. CONCLUSIONS: The prevalence of relevant associated lesions in subjects with acute grade III to VI ACJI is relatively low. Only 14% of subjects have an associated lesion and only half of these required further surgical attention. LEVEL OF EVIDENCE: Retrospective case series, level IV.

SLAP Lesions: Trends in Treatment.

PURPOSE: To determine the trends in SLAP repairs over time, including patient age, and percentage of SLAP repairs versus other common shoulder arthroscopic procedures. METHODS: The records of 4 sports or shoulder/elbow fellowship trained orthopaedic surgeons were used to identify the total number of common shoulder arthroscopic cases performed between 2004 and 2014 using current procedural terminology codes (CPT): 29822, 29823, 29826, 29827, 29806, 29807, 29825, and 29828. The number of SLAP repairs (CPT code 29807) as a combined or isolated procedure were recorded, and the classification of SLAP type was undertaken using operative reports. Patient age was recorded. Linear regression was used to determine statistical significance. RESULTS: There were 9,765 patients who underwent arthroscopic shoulder procedures using the defined CPT codes between 2004 and 2014 by our 4 orthopaedic surgeons. Of these, 619 underwent a SLAP repair (6.3%); average age 31.2 ± 11.9. The age of patients undergoing SLAP repair significantly decreased over time (P < .001, R(2) = 0.794). Most SLAP repairs were performed on type II SLAP tears (P = .015, R(2) = 0.503). The percentage of SLAP repairs compared with the total number of shoulder arthroscopic surgeries and total number of patients who underwent SLAP repair significantly decreased over time (P < .001, R(2) = 0.832 and P = .002, R(2) = 0.674, respectively). Conversely, the number and percentage of biceps tenodeses are increasing over time (P = .0024 and P = .0099, respectively). CONCLUSIONS: Over the past 10 years, the total number of biceps tenodeses has increased, whereas the number and relative percentage of SLAP repairs within our practice have decreased. The average age of patients undergoing SLAP repair is decreasing, and most SLAP repairs are performed for type II SLAP tears. LEVEL OF EVIDENCE: Level IV, therapeutic case series.
