Where is the arcade of Struthers?
According to the standard anatomic definition, the arcade of Struthers is a thin fibrous band that usually extends from the medial head of the triceps to the medial intermuscular septum. It is often said to be about 6-10 cm proximal to the medial epicondyle.
What is the ligament of Struthers?
Struthers’ ligament is a feature of human anatomy consisting of a band of connective tissue at the medial aspect of the distal humerus. It courses from the supracondylar process of the humerus (also known as avian spur) to the medial humeral epicondyle. It is not a constant ligament, and can be acquired or congenital.
What is the medial intermuscular septum?
The medial intermuscular septum of thigh is a fold of deep fascia in the thigh. It is between the vastus medialis, and the adductors and pectineus. It separates the anterior compartment of the thigh from the medial compartment of the thigh.
What makes up the cubital tunnel?
The cubital tunnel is a space of the dorsal medial elbow which allows passage of the ulnar nerve around the elbow. It is bordered medially by the medial epicondyle of the humerus, laterally by the olecranon process of the ulna and the tendinous arch joining the humeral and ulnar heads of the flexor carpi ulnaris.
What is the arcade of Frohse?
The arcade of Frohse (pronounced “\ˈfʁoːzə \”) is also known as the supinator arch. The arcade is formed by a fibrous band between the two heads of the supinator muscle. The deep branch of the radial nerve passes beneath the arcade accompanied by vessels known as the leash of Henry.
Why is the funny bone?
It doesn’t really hurt as much as it feels weird. The “funny bone” got its nickname because of that funny feeling you get after you hit it. Running down the inside part of your elbow is a nerve called the ulnar nerve. The ulnar nerve lets your brain know about feelings in your fourth and fifth fingers.
What is Martin Gruber syndrome?
It is an anomalous pattern of innervation occurring between the median and ulnar nerves in the forearm. In a Martin-Gruber anastomosis, a crossover of axons from the anterior interosseous nerve (the exclusively motor branch of the median nerve) to the ulnar nerve in the forearm usually occurs.
What is the profunda brachii artery?
The profunda brachii artery also referred to as the deep brachial artery, is the first and largest branch of the brachial artery. It originates from the posterior portion of the brachial artery, just inferior to the lower border of the teres major muscle.
What is the posterior arm?
Anatomical terminology The posterior compartment of the forearm (or extensor compartment) contains twelve muscles which are chiefly responsible for extension of the wrist and digits, and supination of the forearm. It is separated from the anterior compartment by the interosseous membrane between the radius and ulna.
What is palmaris brevis?
Palmaris brevis muscle is a thin, quadrilateral muscle, placed beneath the integument of the ulnar side of the hand. It acts to fold the skin of the hypothenar eminence transversally.
Where is the arcade of Frohse located?
Arcade of Frohse, sometimes called the supinator arch, is the most superior part of the superficial layer of the supinator muscle, and is a fibrous arch over the posterior interosseous nerve.
What is pin palsy?
Posterior Interosseous Nerve (PIN) Palsy is a syndrome characterised by a reduction in extensor movements of the fingers. It most commonly due to a compression at the radial tunnel. This article explores the causes, signs and symptoms, and management of this entrapment.
What is the function of the arcade of Struthers?
The arcade of Struthers is a musculoaponeurotic canal that represents an important site of entrapment or compression of the ulnar nerve. The arcade, the intermuscular septum, and the internal brachial ligament should be released in patients submitted to ulnar nerve anterior transposition surgery.
Is the ulnar nerve under the arcade of Struthers?
The arcade of Struthers was identified in 40 dissected arms (100%). In 29 (72.5%) the ulnar nerve was covered by a muscular arcade, in nine (22.5%) by an aponeurotic arcade, and in two (5%) the arcade was beneath the ulnar nerve.
Is the arcade of Struthers an anatomical study?
The arcade of Struthers: An anatomical study with potential neurosurgical significance. (2011) Surgical neurology international. 2: 184. doi:10.4103/2152-7806.91139 – Pubmed
