An anomalous insertion fascicle of the caput laterale of the triceps brachii. Case report
We report a case of an undescribed anomaly of the triceps brachii muscle during routine cadaver dissections of the upper limb, at the "Nueva Granada" Military University (UMNG) and School of Medicine in Santafé de Bogotá, Colombia. This finding prompted us to review the literature in order to ascertain the prevalence and probable clinical significance of this tendinous structure, which originated distally from the caput laterale of the tricpes brachii and inserted proximally into the scapula, passing directly posterior to the neurovascular bundle containing the axillary nerve and posterior circumflex humeral artery and dividing the spatium axillare laterale (quadrilateral space) in two. A thorough review of the literature failed to disclose any previous reports of this variant and therefore, this report constitutes the first description of this anomaly.
