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.

During dissection in middle-aged male cadaver, an aberrant radial artery was noticed in the left arm. The artery was taking origin from the upper part of the brachial artery i.e. at a point when axillary artery leaves the axilla and becomes brachial artery.Course of the aberrant vessel was studied in the arm and the forearm. In the upper part of arm the vessel took origin on the lateral side of brachial plexus trunks and traveled to the lateral region of the cubital fossa travelling lateral to the biceps brachii and deep to skin, superficial and deep fascia. In the lower part of the arm i.e. just above the cubital fossa, aberrant vessel was lateral and entered the forearm deep to the pronator teres. Throughout its course the vessel laid superficial to forearm muscles, it was covered by the skin superficial and deep fascia. At the wrist its position was normal i.e. against anterior border of the radius.

The axillary arch is a variative muscular slip encountered in the axillary region which usually connects latissimus dorsi to pectoralis major. Reported here is a rare case of bilateral axillary arch splitting the radial nerve into two roots in each side as observed during routine dissection of the axillary region of an old male cadaver. The anatomy, surgical implications, and embryology of the anomalous muscle have been discussed. Clinicians should be aware of its existence as it can give rise to different pathologies. It should be recognised and excised to expose the axillary artery and vein in patients with trauma and to perform axillary lymphadenectomy or axillary bypass. It should be considered in the differential diagnosis of axillary masses or in a history of intermittent axillary vein obstruction.Journal of College of Medical Sciences-Nepal, 2014, Vol-10, No-3, 56-60

AbstractMany authors have reported and classified several anatomical variations between the musculocutaneous (Mc) and median (Me) nerves, regarding their origin, number, and proximity with the coracobrachialis muscle. There also are, in the scientific community, records classifying the origin of supernumerary heads of the biceps brachii muscle. However, the occurrence of both aforementioned variations in the same arm is very uncommon. During a routine dissection of the right upper limb of a male cadaver, a third head of the biceps brachii was found originating from the fibers of the brachialis muscle, as well as a communicating branch between the Mc and the Me nerves, in the same limb. The objective of the present case report is to describe these multiple variations found, relating them and discussing their relevant clinical implications.

Unknown Case

CONTEXT: The musculocutaneous nerve is one of the terminal branches of the lateral fasciculus of the brachial plexus, and is responsible for innervation of the flexor musculature of the elbow and for skin sensitivity on the lateral surface of the forearm. Its absence has been described previously, but its real prevalence is unknown. CASE REPORT: A case of absence of the musculocutaneous nerve that was observed during the dissection of the right arm of a male cadaver is described. The area of innervation was supplied by the median nerve. From this, three branches emerged: one to the coracobrachialis muscle, another to the biceps brachii muscle and the third to the brachialis muscle. This last branch continued as a lateral antebrachial cutaneous nerve. This is an anatomical variation that has clinical-surgical implications, considering that injury to the median nerve in this case would have caused unexpected paralysis of the flexor musculature of the elbow and hypoesthesia of the lateral surface of the forearm.

The facial nerve divides within the parotid gland into upper temporozygomatic and lower cervicofacial branches. The two branches further subdivide and emerge from the parotid gland as five main branches. We observed a rare anomalous branching pattern of the facial nerve along with double parotid duct on the right side of a 50-year-old male cadaver. The two parotid ducts emerged at the level of the anterior border of parotid gland then united to form one single duct thereby opened into the oral cavity. The first duct (D1) emerged from the upper one third of the anterior border of the parotid gland and traversed horizontally for 9 mm to join the second duct. Knowledge of anomalous branching pattern of facial nerve and double parotid ducts may be beneficial for maxillofacial surgeons.

ABSTRACTThe musculocutaneous nerve usually branches out from the lateral cord of brachial plexus. It innervates the corcobrachialis, biceps brachii and brachialis muscles and continues as the lateral cutaneous nerve of forearm without exhibiting any communication with the median nerve or any other nerve. We report unilateral variation in motor innervations of the left arm in a 58-year-old male cadaver. The musculocutaneous nerve was found to be absent. A muscular branch of the median nerve was supplying the coracobrachialis muscle. In the middle of arm, the median nerve was found to be branching out, bifurcating and supplying the long and short head of biceps. The median nerve was found to be giving a separate branch, which supplied the brachialis muscle and continued as the lateral cutaneous nerve of forearm. The right sided structures were found to be normal. Surgeons should keep such variations in mind while performing arm surgeries.

Venous Pattern

Variations of venous pattern in the arm are common. In this case report, we present a variation of axillary artery and vein. During routine educational dissections of axillary region, it was observed that a fenestrated axillary vein was perforated by a variant axillary artery in right arm of an old male cadaver. The axillary artery which was fenestrated through axillary vein had only two branches arising from its second part and no branches from its remaining distal parts. The branches are thoraco-acromial (usual) and another large collateral (unusual) branch. This collateral branch is the origin of several important arteries as the subscapular, circumflex scapular, posterior circumflex humeral and lateral thoracic arteries. We propose to name this artery as collateral axillary arterial trunk. The course of this collateral axillary arterial trunk and its branches and also clinical significance of this variation are discussed in the paper.

AbstractAnomalous muscles donot usually cause symptoms but are of academic interest. Axillary arch is a variable muscular slip encountered in axilla. Purpose of the present study was to report a rare case of axillary arch muscle. Knowledge of this muscle variation and the possibility of finding it during axillary procedures are crucial for lymph node staging, lymphaedenectomy and for differential diagnosis in compressive pathologies of axillary vessels and brachial plexus. During routine dissection of left axilla in a 60-year old male cadaver, an anomalous muscular slip was encountered. The slip was extending between latissimus dorsi muscle to coracoid process, deltoid muscle, fascia covering biceps and coracobrachialis and was confirmed as axillary arch muscle. The embryological basis, genetics and clinical implications have been discussed. This rare variation will be of interest not only to anatomists but also for clinicians and surgeons dealing with this area.

During routine undergraduate dissection in the upper extremities of a 65 years old male cadaver in the department of Anatomy at Dr. PSIMS & RF, coexistence of muscular and neurovascular variants were identified .Muscular variations included presence of additional head(third) of biceps brachii in the left arm, accompanied with medially positioned median nerve in relation to brachial artery bilaterally . Teres minor muscle was not identified and the origin of long head of triceps brachii extended upto the lateral border of scapula on the left side. Both the medial cutaneous nerves of arm and forearm arouse from a single trunk bilaterally. In the right limb the axillary artery showed only four branches instead of six branches, with common trunk for thoraco-acromial and lateral thoracic artery and common trunk for subscapular and posterior circumflex humeral artery. Knowledge of coexistence of these variations would of profound importance surgically and clinically, especially in limb injuries and surgical repairs.
