Abstract Introduction: Saphenous nerve is the longest and largest pure sensory nerve, supplying the medial side of the thigh, leg and foot. Materials and Methods: In the present case study, during routine cadaveric dissection of the antero-medial part of the thigh, an interesting anomalous pattern of saphenous nerve was seen in the right lower limb of a 62 years old embalmed male cadaver from the Department of Human Anatomy, Universiti Putra Malaysia (UPM). Results: This saphenous nerve can be recognised as an unusual anatomical variant in which it gives a motor branch to the sartorius muscle during traversing the adductor canal and it was accompanied by blood vessels at the same time. The nerve continues its usual course and pierces the fascia lata, between the tendon of sartorius and gracilis and becomes subcutaneous. Conclusion: Knowledge of the variant anatomy of the saphenous nerve is important to surgeon in avoiding nerve injuries during adductor canal nerve block, nerve entrapment surgery, reconstructive surgery, pain management services and knee surgery successfully.

AbstractThe Rectus Sternalis muscle is an unusual muscle that is observed on the anterior chest wall. The origin of this muscle is a highly debated variation of the pectoral musculature. We report a case of an abnormal vertically placed muscle - The rectus sternalis muscle, on the right medial side of the anterior chest wall of a male cadaver aged about 80 years. The abnormal presence of this muscle can be misdiagnosed as a breast mass on a routine mammogram. The advantage is its role in reconstruction flap surgeries. Hence knowledge of such an anatomical variant should be kept in mind during diagnostic investigations and surgical procedures.

Burning pain at the medial thigh or knee area with aggravation after physical activity (such as running) may be caused by saphenous nerve entrapment at the adductor canal. Saphenous neuropathy may arise spontaneously or secondary to trauma or a surgical procedure. The differential diagnosis includes knee pathologies (e.g., medial meniscal tear or patellofemoral disorders) and others. Venous insufficiency may also mimic symptoms of saphenous entrapment syndrome. Careful anamnesis and examination as well as a saphenous nerve block help to make the right diagnosis. If conservative management with physical therapy and pain medication is not effective, surgical options include neurolysis or neurectomy of the saphenous nerve.

Los fascículos musculares accesorios se observan raras veces en relación al músculo sartorio (MS) de la extremidad inferior. La descripción del caso existente informa una presencia poco común de un fascículo muscular accesorio visto pasar del MS al músculo vasto medial (VM) encontrado unilateralmente en la cara anterior del muslo derecho de un cadáver masculino indio adulto. La anomalía fue observada por accidente mientras se mostraba la cara extensora del muslo a los estudiantes de pregrado. Deseamos llamar la atención sobre los diversos aspectos de los usos clínicos de tal músculo supernumerario. Los ecografistas deben ser conscientes de la posible presencia de fascículos musculares accesorios mientras investigan esta región antes de la anestesia o de la exploración de esta área. Este músculo accesorio poco común se debe citar en los textos clínicos para advertir a los cirujanos reconstructivos y a los radiólogos.  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.

AbstractHypoplasia of the vertebral artery (VA) is rare, and incidentally encountered in radiological imaging techniques. During routine activities in the Laboratory of Human Anatomy from University of Santa Cruz do Sul, Brazil, it was observed a 70 years old male cadaver with hypoplasia of the right VA. Thus, the purpose of this study is to report this case of hypoplasia of the VA emphasizing some morphological, functional and clinical data about this rare vascular abnormality, in order to offer useful information to anatomists, radiologists, vascular and head and neck surgeons. Moreover, to our knowledge, this variation has not been cited in recent medical literature.

<div class="WordSection1"><p><strong>Objective</strong>. The study adds important information regarding the descriptive anatomy of a very rarely reported unilateral chondrocoracoideus muscle (of Wood). Additionally it highlights the concomitant muscular and neural alterations. <strong>Case report. </strong>The current case presents the occurrence of a chondrocoracoideus muscle situated left-sided, as an extension of the abdominal portion of the pectoralis major muscle (PM). The chondrocoracoideus coexisted with a contralateral atypical PM, partially blended with the clavicular fibers of the deltoid muscle. There was an accessory head of the biceps brachii while the palmaris longus was absent on the right side of a 78-year-old Greek male cadaver. <strong>Conclusion</strong>. The above mentioned muscular abnormalities are shown as disturbances of embryological pectoral muscle development, and their documentation is essential in order to increase awareness among clinicians of their potential impact on the diagnosis and treatment of several pathologies.</p></div>

Durante la embriogénesis renal, ocurren fenómenos en su desarrollo que, de persistir en el adulto, se describen como variantes anatómicas. La presencia de arterias renales supernumerarias es una de variantes más frecuentes, pero la triplicidad de estas es rara.  Este trabajo tiene como objetivo reportar un caso de arterias renales supernumerarias derechas e izquierdas. El hallazgo se produjo durante una sesión de disección en los laboratorios docentes de anatomía humana de la universidad. El caso consiste en un bloque anatómico de cadáver femenino del cual se aisló el segmento urogenital. El mismo fue disecado en fresco por el método macroscópico directo y luego conservado en formol por el método de Thiel durante 10 días, para luego ser examinado y fotografiado. El bloque consta de dos riñones, derecho e izquierdo, con sus vasos arteriales y venosos unidos a la arteria aorta abdominal y vena cava inferior respectivamente. Las arterias renales halladas fueron cinco, mostrando una triplicidad de arterias renales derechas con duplicidad de izquierdas. Las arterias renales derechas presentan similar calibre y dos de sus ramas son arterias polares superiores, en el caso de las arterias izquierdas la superior presentó mayor calibre. Asociada a esta variante se encontró la vena renal izquierda en posición posterior a la arteria renal inferior izquierda. Es importante para la práctica médica conocer las posibles variantes vasculares renales que pueden presentarse, para efectuar correctos procedimientos diagnósticos radiológicos, así como las planificaciones preoperatorias adecuadas de intervenciones quirúrgicas. During renal embryogenesis, phenomena occur in its development that, if persist in adult age, will be described as anatomical variant. The presence of supernumerary renal arteries is one of the most frequent variants, but the triplicity of these is rare. The objective of this work is to report a case of right and left supernumerary renal arteries. This finding appeared during a dissection session at the university's laboratory of human anatomy. The report case consists on an anatomical block of a female cadaver from which the urogenital piece was isolated. It was dissected fresh by the direct macroscopic method and then preserved in formaldehyde by the Thiel’s method for 10 days, to be examined and photographed. The block consisted on two kidneys, right and left, with their arterial and venous vessels attached to the abdominal aorta and inferior vena cava respectively. After the initial examination, five renal arteries were found, including a triplicity of right renal arteries and duplicity of left one. The right renal arteries have a similar caliber, with two branches as superior polar arteries. In regard to the left arteries, the superior artery presented greater caliber. Associated to these variants, left renal vein was in a posterior position in relation to the artery. It is important for medical practice to know the possible renal vascular variants that may occur, to carry out correct radiological diagnostic procedures and to adequately plan preoperative surgical interventions.

Brachial plexus is the plexus of nerves, that supplies the upper limb.Variations in the branches of brachial plexus are common but variations in the roots and trunks are very rare. Here, we report one of the such rare variations in the formations of the lower trunk of the brachial plexus in the right upper limb of a male cadaver. In the present case the lower trunk was formed by the union of ventral rami of C7,C8 and T1 nerve roots. The middle trunk was absent. Upper trunk formation was normal.

AbstractThe coexistence of different muscular-neurovascular variations is of significant clinical importance. A male cadaver, 76 years old at death, was subjected to routine anatomical dissection; the procedure was performed for research and teaching purposes at the Department of Anatomical Dissection and Donation, Medical University of Lodz. The right forearm and hand were dissected using standard techniques according to a strictly specified protocol. The presence accessory head of the flexor pollicis longus may potentially compress the anterior interosseous nerve. The present case report describes a rare variant of the ulnar head of the pronator teres, characterized by two independent bands (i.e., two proximal attachments). The main band originates from the coronoid process and the second originates from the tendon of the biceps brachii. This type of attachment could potentially affect the compression of the ulnar artery running between the two bands. Additionally, the accessory head of the flexor pollicis longus was observed, which started on the medial epicondyle; its coexistence with a high division median nerve creates a potential pressure site on the anterior interesosseous nerve.

This report analyzes the experience gained using two different techniques to reinnervate the paralyzed vocal cord. In the neurotization group, the superior laryngeal nerve (SLN) motor branch–cricothyroid muscle pedicle was used to reinnervate the posterior cricoarytenoid muscle. In the direct nerve anastomosis group, the SLN was anastomosed to the abductor branch of the recurrent laryngeal nerve (RLN), and the ansa hypoglossi (AH) to the adductor branch of the RLN. A third group of animals (control) had the right RLN sectioned without any anastomosis. About 5 to 6 months postoperatively the animals were killed painlessly and evaluated. The neurotization group revealed vocal fold mobilization on the right side to have an average of about half of the mobility of the left, normal side. After the RLN and SLN on the left were severed as well as the AH bilaterally, the vocal cord mobility was reduced to about one fourth. The direct nerve anastomosis group showed about fourfold less vocal cord mobility than the neurotization group. After the SLN, RLN, and AH were severed bilaterally, the control group showed no vocal cord mobility. The neurotization technique has been selected for further experimentation in human adults.

Introduction: In human anatomy the acetabulum is a cavity on the lateral aspect of the hip-bone. The purpose of this study is to record the depth and diameter of the acetabulum cavity to accumulate morphological data helpful for anthropologists, Forensic medicine experts and orthopedicians. Materials And Methods: The study was done on 88 adult human hip bones (42 right and 46 left) collected from Department of Anatomy, Govt.T.D Medical College, Alappuzha, Kerala state. The diameters and maximum depth were measured using digital vernier calliper. The measurements were compared with other studies in the world. The mean diam Results: eter of acetabulum was 48.08 ± 3.21mm, 44.16 ± 2.60 mm in male and female respectively. The mean ± S.D value of depth was 29.11± 2.37 and 27.20± 2.01 mm. in male and female respectively. The correlation between depth and diameter was signicant only in the right male hip bones. There is signicant variation in the Conclusion: anatomical parameters of hip bone between different Indian population groups. The data from this study may be used for designing population specic hip prosthesis.
