“…El tendón del músculo bíceps braquial es uno de los tendones con mayor variabilidad de la anatomía humana; el hallazgo más frecuente son las terminaciones supernumerarias y las variaciones en su origen intraarticular. La ausencia del TPLB es una anomalía infrecuente (1)(2)(3)(4)(5) . Revisando la bibliografía (Tabla 1) se encontraron 17 casos de agenesia, 6…”

Asociación Española de Artroscopia REVISTA ESPAÑOLA DE ARTROSCOPIA Y CIRUGÍA ARTICULAR RESUMEN Presentamos el caso de un paciente varón de 49 años intervenido por presentar un síndrome subacromial derecho crónico refractario a tratamiento médico y rehabilitador. En el tiempo artroscópico intraarticular se apreció la ausencia completa del tendón de la porción larga del músculo bíceps braquial, que no se había objetivado en el estudio clínico y de imagen previo a la cirugía. En el postoperatorio se estudió el hombro contralateral y se comprobó la ausencia bilateral de la porción larga del músculo bíceps braquial. Dada la infrecuencia de esta anomalía, se revisa la bibliografía y su patogenia. Palabras clave: Hombro. Porción larga músculo bíceps braquial. Artroscopia. Agenesia. Síndrome subacromial.

SummaryBackground: Multiple reports of congenitally absent long head of biceps tendon (LHBT) have been reported in the literature. However, there is no consensus on the clinical implications of this relatively rare entity. Study Purpose: To systematically review and analyze all studies which have reported absence of LHBT. Methods: PubMed and EMBASE databases were searched. Also, a secondary search was performed by pearling the bibliography of all the fulltext articles obtained. Pre defined inclusion criteria was used for abstract screening by two independent observers. Twenty three studies met our inclusion criteria, were included for the final analysis and the data was pooled. The cases were further sub-grouped according to the classification of Dierickx et al. Results: Till date, 35 cases of absent LHBT have been reported. Males and females were equally affected. Eight of these were bilateral and only four cases had other associated congenital anomalies. Majority of the patients presented with shoulder pain (85.7%) while 37.1% had shoulder instability (mainly anterior instability). The ABS type was the most common variant reported. The finding was missed in 60% of the cases on the initial MRI only to be detected later on shoulder arthroscopy. Conclusions: Congenitally absent LHBT may not be as rare as was previously thought to be. Due to the heterogeneity and the low level of evidence of the data available, it is hard to conclude if a congenitally absent LHBT is a cause of shoulder pain/impingement or instability on its own. Level of evidence: IV.

Case report: Broad insertion of a large subscapularis tendon in association with congenital absence of the long head of the biceps tendon

Congenital absence of the long head of the biceps (LHB) tendon is a rare variation in shoulder anatomy. The authors present a case of congenital absence of the long head of the biceps tendon associated with a large insertion of the subscapularis muscle. The patient initially presented with shoulder pain on overhead activity. Shoulder examination was negative for signs of a torn biceps tendon. MRI revealed congenital absence of the LHB tendon, a rim rent tear of the supraspinatus, and a large insertion of the subscapularis muscle. This is the first reported case describing a large insertion of the subscapularis muscle associated with absence of the LHB tendon.5.
