jugulo facial venous circle Accessory slip of trapezius and absence of typical facial vein clinically important anatomical variations
Journal of The Anatomical Society of India, 2017Co-Authors: Nayak SatheeshaAbstract:Abstract Knowledge of facial and external jugular vein variations is useful for medical disciplines such as radiology, anesthesia, general surgery and plastic surgery for the success in their procedures in the head and neck region. I report a unique combination of venous and muscular variation in the left side of the neck of an adult male cadaver. The typical facial vein was absent. Facial vein was represented as a vena comitans of facial artery. The common facial vein joined with the external jugular vein to form a jugulo-facial venous circle above the lateral part of the clavicle. This circle was closely related to an Accessory Muscle slip from the trapezius. Further, the common facial vein was connected to the anterior jugular vein through a large anonymous vein. I discuss the clinical implications of these variations.

A CLINICO-ANATOMICAL REPORT OF AN Accessory Muscle FASCICLE EMANATING FROM SARTORIUS Muscle
2020Co-Authors: Vandana Mehta, Ashwini Kumar, Jyoti Arora, Gayatri RathAbstract:Accessory Muscle fascicles are rarely observed in relation to the sartorius Muscle (SM) of the lower extremity. The existing case description reports a rare presence of an Accessory Muscle fascicle seen to pass from the SM to the vastus medialis Muscle (VM) found unilaterally in the anterior aspect of the right thigh of an adult Indian male cadaver. The anomaly was observed accidentally while demonstrating the extensor aspect of the thigh to the undergraduate students. We wish to bring attention to the various aspects of clinical usages of such a supernumerary Muscle. Ultrasonologists should be aware of the possible presence of Accessory Muscle fascicles while investigating this region prior to anesthesia or exploration of this area. This unusual Accessory Muscle should be cited in clinical texts for cautioning the reconstructive surgeons and the radiologists.

Clinico-anatomical description of an Accessory flexor pollicis longus.
Clinica Terapeutica, 2020Co-Authors: Mehta, Suri Rk, Arora J, Gayatri RathAbstract:: Several instances of Accessory musculature of the upper extremity are now recognized. During regular dissection class of undergraduate medical students, we observed an important anatomic variation pertaining to the flexor pollicis longus Muscle (FPL) in the left upper limb of an adult male cadaver. An Accessory Muscle belly extending from the deep aspect of flexor digitorum superficialis (FDS) to the tendon of the FPL was observed in the flexor surface of the antebrachium. The description of Gantzer's Muscle (GM) is well elucidated in anatomical archives and is described as an Accessory Muscle extending from the superficial to the deep flexors of the digits.

Anomalous constitution of the brachioradialis Muscle: a potential site of radial nerve entrapment.
Clinica Terapeutica, 2020Co-Authors: Vandana Mehta, Jyoti Arora, Rajesh Kumar Suri, Gayatri RathAbstract:: The anatomical relationships of structures in the elbow region in the context of surgical approaches require to be studied carefully and diligently. The main aim of the present study is to report an Accessory Muscle in the elbow region which was detected during routine anatomical dissection and discuss its clinical importance. The Muscle belly measured 4.8 x 2.1cm and it fused with the brachioradialis distally. Proximally, it was seen to blend with the deltoid and the brachialis Muscles. The radial nerve was observed to interpose between this Accessory Muscle and the brachioradialis. This could act as a potential site of compression neuropathy. The present study seeks to elucidate the morphology and potential function of an additional Muscle belly in relation to the brachioradialis Muscle. A comprehensive knowledge of the anatomical characteristics of brachialis, brachioradialis and radial nerve should prove extremely helpful for the hand surgeons to considerably reduce the risk of injury during operative maneuvers.

A CLINICO-ANATOMICAL REPORT OF AN Accessory Muscle FASCICLE EMANATING FROM SARTORIUS Muscle. Informe anatomo-clínico de un fascículo muscular accesorio que emana del músculo sartorio
Revista Argentina de Anatomía Clínica, 2016Co-Authors: Vandana Mehta, Ashwini Kumar, Arora J, Suri Rk, Gayatri RathAbstract:Los fasciculos musculares accesorios se observan raras veces en relacion al musculo sartorio (MS) de la extremidad inferior. La descripcion del caso existente informa una presencia poco comun de un fasciculo muscular accesorio visto pasar del MS al musculo vasto medial (VM) encontrado unilateralmente en la cara anterior del muslo derecho de un cadaver masculino indio adulto. La anomalia fue observada por accidente mientras se mostraba la cara extensora del muslo a los estudiantes de pregrado. Deseamos llamar la atencion sobre los diversos aspectos de los usos clinicos de tal musculo supernumerario. Los ecografistas deben ser conscientes de la posible presencia de fasciculos musculares accesorios mientras investigan esta region antes de la anestesia o de la exploracion de esta area. Este musculo accesorio poco comun se debe citar en los textos clinicos para advertir a los cirujanos reconstructivos y a los radiologos.

Accessory Muscle belly of peroneus tertius in the leg a rare anatomical variation with clinical relevance utility in reconstructions
Morphologie, 2011Co-Authors: Vandana Mehta, Vanita Gupta, A Nayyar, J Arora, R K Suri, Gayatri RathAbstract:Summary We report here a rare muscular anomaly of the lower leg in an adult male cadaver observed during routine cadaveric dissection. Peroneus tertius (PT) is peculiar to man, being a hallmark of bipedal locomotion and erect posture. During the course of gross anatomy dissection, a rare finding of Accessory belly of PT Muscle was discovered. A meticulous dissection was performed and the observations were noted. The PT displayed two distinct bellies of origin. Both the bellies were substantial in size and were eventually fused close to their insertion at the base of the fifth meta-tarsal bone. Innervation of both the bellies was derived from the deep peroneal nerve. Soft tissue defects of the leg may be effectively covered by local Muscles in the vicinity of the wounds. PT has been reliably used in the past for local transposition flaps in the lower extremities. The relations of the superficial nerve and the PT during placement of the anterolateral portal in ankle arthroscopy are vital to avoid inadvertent neuromuscular injuries. The presence of two bellies of the PT Muscle has been discussed in the comparative perspective. A precise and detailed knowledge of the anatomical details of the crural Muscles is important for performing reconstructive surgeries.

Accessory Muscle in the forearm a clinical and embryological approach
Anatomy & Cell Biology, 2011Co-Authors: Engin Ciftcioglu, Cem Kopuz, Ufuk Corumlu, Mehmet Tevfik DemirAbstract:Muscular variations of the flexor compartment of forearm are usual and can result in multiple clinical conditions limiting the functions of forearm and hand. The variations of the Muscles, especially Accessory Muscles may simulate soft tissue tumors and can result in nerve compressions. During a routine dissection of the anterior region of the forearm and hand, an unusual Muscle was observed on the left side of a 65-year-old male cadaver. The anomalous Muscle belly arose from the medial epicondyle approxiamately 1 cm posterolateral to origin of normal flexor carpi ulnaris Muscle (FCU), and from proximal part of the flexor digitorum superficialis Muscle. It inserted to the triquetral, hamate bones and flexor retinaculum. Passive traction on the tendon of Accessory Muscle resulted in flexion of radiocarpal junction. The FCU which had one head, inserted to the pisiform bone hook of hamate and palmar aponeurosis. Its contiguous Muscles displayed normal morphology. Knowledge of the existence of Muscle anomalies as well as the location of compression is useful in determining the pathology and appropriate treatment for compressive neuropathies. In this study, a rare Accessory Muscle has been described.

Case reports with special reference to the innervation, development and clinical significance of the subclavius posticus and the termination of the facial vein in South Indian cadavers
European journal of anatomy, 2008Co-Authors: Suganthy J. Rabi, Chintha MadhaviAbstract:During the routine dissection of the head and neck, a variation in the termination of the common facial vein was noticed in two (a male aged 93 years and a female aged 53 years) South Indian cadavers. In the male, an Accessory Muscle, the subclavius posticus was also observed in the left posterior triangle. The Muscle was attached posteriorly to the superior angle and the adjoining part of the superior border of the scapula along with the attachment of the inferior belly of the omohyoid Muscle. Anteriorly, the Muscle was attached to the first costal cartilage. On its course, this Muscle crossed the brachial plexus and subclavian vessels anteriorly and was innervated by the suprascapular nerve. The relationship of this Muscle to the neurovascular structures in the neck should be borne in mind while accessing the thoracic outlet syndrome. In addition to this, the common facial vein joined the external jugular vein on the left side. In the female cadaver the termination of the common facial vein was also into the external jugular vein on the left side, but no Accessory Muscle was found. Knowledge of the variation of the vein is important for the intravenous canulation, for therapeutic or diagnostic purposes, and for the surgeons performing reconstructive surgery.
