– Discussion: – motivation: w/ maximal elbow flexion, high extraneural pressures occur at the medial epicondyle; – hence the medial epicondyle is a major impinging structure which forces the ulnar nerve to make a sharp turn whenever the elbow is maximally flexed; – medial … Read more
– See: Medial Approach: – Discussion: – medial epicondyle is common origin of several flexor muscles of hand and wrist; – when medial epicondyle is frxed, flexor muscles pull fragment distally; – during surgical procedure care must be made to protect ulnar nerve; – Fixation Stratedgy: – … Read more
– Anatomy: – arises from anterior division of lower trunk: C8 & T1; – medial cord branches into ulnar nerve & the medial root of the median nerve; – medial pectoral – medial branchial cutaneous – medial antebrachial cutaneous – division of medial … Read more
– See: – Pediatric Elbow Injuries – distal humeral physeal separation – lateral condyle frx, pediatric – supracondylar frx of humerus – Discussion: – third most common pediatric elbow frx (5-10%) (behind supracondylar and lateral condylar fractures); – most common between ages of 9 … Read more
– Discussion: – may begin as a microtear between the pronator teres and the FCR; – often associated w/ ulnar neuritis (see cubital tunnel); – Exam: – tenderness over the origin of the forearm flexors; – resisted pronation and/or flexion will elicit pain in most patients; … Read more
– See: Anteromedial Approach – Discussion: – may be used for frx dislocations of talus, traumatic injuries to ankle joint, and osteochondritis dissecans of the talus; – disadvantages: possible to injure the tibial vessels and nerves; – incision: – centered on malleolus & is made … Read more
– Discussion: – allow visualization of medial epicondyle, trochlea, and ulnar nerve are – approach is used for a total elbow arthroplasty; – proximally the interval lies between the brachialis and triceps, where as distally the interval lies between the brachialis and MCL; – avoid … Read more
– Anatomy: – innervation: (C8, T1); – medial antebrachial cutaneous nerve descends in the arm anterior and medial to brachial artery; – at distal to mid forearm level, nerve emerges from under brachial fascia adjacent to basilic vein; – it innervates the skin of anterior & medial … Read more
– Discussion: – optimal age for the medial approach: – is of more value in the child younger than 18 months but older than 7 months; – when this procedure is used in infants younger than 7 months, there may be … Read more
– Discussion: – motor nerve may cross over from the median to ulnar nerve in the forearm; (motor connections but not sensory connections); – it occurs in two patterns: – from median nerve in proximal forearm to ulnar nerve in middle to distal third of forearm, & from AIN to … Read more
