“…The whole muscle extends distally to be inserted via a common tendon onto the olecranon. according to Keener et al [4], in 14 specimens aged 71 years, the mean tendon width at its insertion was found to be approximately 78% of the maximum width of the olecranon.…”

“…The triceps brachii may get accessory muscle slips arising from the humerus, shoulder capsule, coracoid process, and even from some muscles, such as the subscapularis, latissimus dorsi, anconeus, and extensor carpi ulnaris [2][3][4][5][6][7][8][9]. The aforementioned anatomical variations of the triceps brachii are known to potentially cause compression of the radial and ulnar nerves [2,8,9].…”

Background. The triceps brachii muscle, the strongest extensor of the elbow joint, is characterized by the three heads: long, lateral and medial. Objectives. In the present study we aimed to examine the linear parameters (length, width) of the fetal triceps brachii muscle and to provide their growth dynamics. Material and Methods. Using anatomical dissection, digital image analysis (Multiscan v.14.02), and statistics (Student's t-test, regression analysis) we measured in mm the length and width of the triceps brachii in 30 fetuses of both sexes (12♂,18♀) aged 12-29 weeks. Results. Neither sex nor laterality differences were found. all the parameters studied increased proportionately with age. The linear functions were computed as follows: y = 6.797 + 2.079 x age (r = 0.886) for length of the long head's belly, y = -0.041 + 0.215 × age (r = 0.786) for width of the long head's belly, y = 1.889 + 0.174 × age (r = 0.796) for length of the long head's proximal tendon, y = 0.158 + 0.052 × age (r = 0.864) for width of the long head's proximal tendon, y = 5.270 + 1.809 × age (r = 0.855) for length of the lateral head's belly, y = 0.348 + 0.284 × × age (r = 0.829) for width of the lateral head's belly, y = 0.942 + 1.837 × age (r = 0.839) for length of the medial head's belly, y = 0.314 + 0.234 × age (r = 0.852) for width of the medial head's belly, y = -3.191 + 0.984 × age (r = 0.929) for lenght of the common tendon, and y = -0.478 + 0.133 × age (r = 0.933) for width of the common tendon. Conclusions. Neither male-female nor right-left differences are observed in morphometric parameters of the triceps brachii muscle. The long head's belly is the thinnest, while the lateral head's belly is the widest one. The long head is the longest and the medial head is the shortest one. The developmental dynamics of the triceps brachii muscle follow proportionately (Adv Clin Exp Med 2014, 23, 2, 177-184).

76 ResumenObjetivo: Reportar los resultados clínicos y radiológicos del tratamiento funcional de fracturas desplazadas de olécranon en pacientes >70 años. Materiales y Métodos: Se evaluaron 28 pacientes >70 años con fracturas desplazadas de olécranon. El tratamiento consistió en la inmovilización inicial con una valva de yeso (promedio 5 días) y, luego, movilización activa según tolerancia. No se indicó rehabilitación kinesiológica. Ningún paciente fue perdido en el seguimiento. El grupo estaba formado por 27 mujeres y un hombre. La edad promedio era de 82 años. Según la clasificación de la Clínica Mayo, 18 fracturas eran de tipo IIA y 10, de tipo IIB. El seguimiento promedio fue de 14 meses. Resultados: La flexo-extensión fue de 142°-15°. La fuerza muscular fue de M5 en 17 pacientes y de M4 en 9. La fuerza de puño fue un 93% del lado contralateral. El dolor según la escala visual analógica fue de 1. La satisfacción con el tratamiento según esta escala fue de 9. Según el puntaje de la Clínica Mayo, 22 pacientes tuvieron resultados excelentes y 6, buenos. El puntaje DASH promedio fue de 15. Veinticuatro pacientes evolucionaron hacia la seudoartrosis. El gap articular final fue, en promedio, de 16 mm. El gap a nivel de la cortical posterior final fue, en promedio de 22 mm. Conclusión: El tratamiento no quirúrgico de las fracturas desplazadas de olécranon en pacientes mayores ofrece un nú-mero elevado de buenos resultados funcionales con alto grado de satisfacción.Palabras clave : Fractura de olécranon.

Nivel de evidencia: IV Functional treatment of displaced olecranon fractures in patients older than 70 years AbstractObjective: To report the clinical and radiological outcomes of the functional treatment for displaced olecranon fractures in patients >70 years old. Methods: Twenty-eight patients >70 years old with displaced olecranon fractures were evaluated. The treatment included initial immobilization with a cast (average time 5 days) and then active movement as tolerated. Physiotherapy was not indicated. No patients were lost in the follow-up. The study group included 27 women and a man. Average age was 82 years old. According to the Mayo Clinic Classification, 18 fractures were type IIA and 10 were type IIB. Average followup was 14 months. Results: Flexion-extension was of 142°-15°. Muscular strength of the triceps was M5 in 17 patients and M4 in 9. Grip strength was 93% of the contralateral side. The score in the visual analogue scale for pain was 1. Satisfaction with the treatment according to this scale was 9. According to the Mayo Clinic classification, 22 patients presented excellent results, and 6 good results. Average DASH score was 15. Twenty-four patients evolved to a nonunion. Mean final joint gap was 16 mm. Mean final gap at the posterior cortical level of the olecranon was 22 mm.Tratamiento funcional de fracturas desplazadas de olécranon en pacientes mayores de 70 años

“…It is also unlikely that a great deal of slack accumulates in the anconeus. The superficial anconeus tendon spans ϳ70% of the muscle length, but the length of the tendon in series with anconeus muscle fibers is very short compared with that of other muscles (Keener et al 2010;Pereira 2013). Moreover, the anconeus is active at all elbow joint angles (Le Bozec et al 1980a), and thus slackening of its elastic elements would likely only accumulate in a hyperextended position when the anconeus is inactive.…”
