“…Subscapularis tendon tears were found in 61.7% (74/120) of the patients undergoing arthroscopy for rotator cuff repair. This is a slightly higher prevalence compared to those reported in previous published literature (10–58.8%) ( 11 17 22 23 24 25 26 27 28 ). The prevalence of SSC tendon tears has been reported in a variety of ranges depending on the included patients of the studies.…”

ObjectiveTo compare the T1-weighted spectral presaturation with inversion-recovery sequences (T1 SPIR) with T2-weighted turbo spin-echo sequences (T2 TSE) on 3T magnetic resonance arthrography (MRA) in the evaluation of the subscapularis (SSC) tendon tear with arthroscopic findings as the reference standard.Materials and MethodsThis retrospective study included 120 consecutive patients who had undergone MRA within 3 months between April and December 2015. Two musculoskeletal radiologists blinded to the arthroscopic results evaluated T1 SPIR and T2 TSE images in separate sessions for the integrity of the SSC tendon, examining normal/articular-surface partial-thickness tear (PTTa)/full-thickness tear (FTT). Diagnostic performance of T1 SPIR and T2 TSE was calculated with arthroscopic results as the reference standard, and sensitivity, specificity, and accuracy were compared using the McNemar test. Interobserver agreement was measured with kappa (κ) statistics.ResultsThere were 74 SSC tendon tears (36 PTTa and 38 FTT) confirmed by arthroscopy. Significant differences were found in the sensitivity and accuracy between T1 SPIR and T2 TSE using the McNemar test, with respective rates of 95.9–94.6% vs. 71.6–75.7% and 90.8–91.7% vs. 79.2–83.3% for detecting tear; 55.3% vs. 31.6–34.2% and 85.8% vs. 78.3–79.2%, respectively, for FTT; and 91.7–97.2% vs. 58.3–61.1% and 89% vs. 78–79.3%, respectively, for PTTa. Interobserver agreement for T1 SPIR was almost perfect for T1 SPIR (κ = 0.839) and substantial for T2 TSE (κ = 0.769).ConclusionT1-weighted spectral presaturation with inversion-recovery sequences is more sensitive and accurate compared to T2 TSE in detecting SSC tendon tear on 3T MRA.

“…Especially smaller tears are difficult to identify with MRI preoperatively. Partial tears, graded as type 1 according to Lafosse or Fox and Romeo are diagnosed with magnetic resonance imaging only with an accuracy of 70% [14,23,25]. Therefore, the gold standard to identify partial subscapularis lesions remains arthroscopy [2,5,13].…”

The aim of the study was to analyze partial subscapularis tendon (SSC) tears and provide a descriptive classification. Methods The retrospective study included 50 patients with arthroscopically confirmed partial SSC tears. Internal rotation (IR) force measurements and IR ROM have been made and compared to the healthy contralateral side. Then the footprint of the SSC was routinely investigated by arthroscopy with standardized measurement of the bony footprint lesion. The partial tears were classified according to the mediolateral and craniocaudal extension of the rupture in the transverse and coronal plane, respectively. Results Partial SSC tears could be classified into split lesions (type 1, n = 11) and 3 further groups depending on the mediolateral peeled-off length of the bony footprint (type 2: < 10 mm, n = 20; type 3: 10-15 mm, n = 10; type 4: > 15 mm, n = 9). Type 2-4 could be further divided depending on the craniocaudal peeled-off length of the bony footprint (group A: < 10 mm, group B: 10-15 mm, group C: > 15 mm). Significantly decreased IR strength was shown for types 2-4 (p < 0.05) but not for split lesions as compared to healthy side. Types 1-4 showed significant decreased active IR ROM and all except type 3 (n.s.) which showed decreased passive IR ROM compared to the healthy side (p < 0.05). Conclusion We present a novel classification for partial SSC tears for a more detailed and reproducible description. This can help to improve the current knowledge about the appropriate treatment. It could be shown that partial tears of the subscapularis can have an impact on IR strength and motion.

RESUMENObjetivo: mostrar el diagnóstico, la técnica quirúrgica y nuestros resultados de la sutura por vía artroscópica de las roturas completas del tendón del subescapular. Métodos: se han incluido los pacientes intervenidos en nuestro hospital entre los años 2014 y 2016 de rotura completa del tendón del subescapular, comprendiendo tanto las lesiones agudas como crónicas. Para la evaluación se objetivó la movilidad articular y se realizó la escala visual analógica (EVA) para el dolor y el test de Constant-Murley previo a la cirugía, a las 6 semanas, 3 y 6 meses posquirúr-gicos y al alta clínica. Resultados: se incluyen 13 pacientes. Edad media de 57,5 (24-73). El tiempo medio transcurrido entre la lesión y el tratamiento fue de 18 semanas (2-48). El tiempo medio de seguimiento fue de 7 meses (rango: 5-12). El tiempo medio de inmovilización fue de 5,6 semanas (4-6). Realizaron rehabilitación durante 4,2 meses (3-6). La EVA final fue de 0,3 (0-4), el Constant-Murley de 87 (65-95) y, en cuanto a la movilidad, la rotación externa fue de 53,2 (45-60), la flexión anterior de 165,5 (155-180) y la abducción de 162,7 (140-180). Conclusión: en la exploración física no debemos olvidar las maniobras para descartar lesiones del tendón del subescapular. Es una patología que tiene que diagnosticarse y tratarse lo antes posible para tener menor dificultad técnica y obtener mejores resultados. En nuestra serie, los casos agudos se presentan en pacientes más jóvenes, tienen lesiones ABSTRACT Arthroscopic suture of the subscapularis tendon.

Methods: all patients operated at our hospital between 2014 and 2016 had a complete subscapular tendon rupture, including both acute and chronic injuries. For the evaluation the ranges of movement was recorded and visual analogue scale (VAS) for pain and Constant-Murley score were performed before surgery, 6 weeks, 3, 6 months and at discharge. Results: we included 13 patients. Mean age of 57.5 (24-73). Time elapsed between injury and treatment was 18 weeks (2-48), mean follow-up was 7 months (5-12), mean time for immobilization was 5.6 weeks (4-6). Rehabilitation performed for 4.2 months (3-6). VAS at discharge was 0.3 (0-4), Constant-Murley score 87 (65-95) and in mobility the external rotation was 53.2 (45-60), forward flexion of 165.5 (155-180) and abduction 162.7 (140-180).
