– Discussion: – at wrist, Lister’s tubercle is palpable on dorsum of radius; – it serves as a pulley for the EPL; – radial and ulnar styloid processes are also palpable, w/ tip of radial styloid process projecting 1 cm distal to that of ulna; – on … Read more
– Volar Wrist Ligaments: – ligaments of wrist are most highly developed on palmar side of wrist; – palmar wrist ligaments originate laterally from radial styloid, & are directed in a distal ulnar direction; – intrinsic ligaments: – radial ligaments arise on palmar facet of radial styloid passing on to capitate; – ulnar sided intrinsic … Read more
Case Example by Dr. James R. Urbaniak MD – Discussion: – indicated for patients with basal joint arthritis or CMC instability; – LRTI involves partial or complete resection of the trapezium and recreation of the palmar oblique ligament using the distally based radial half of FCR to reconstruct ligamentous support for the metacarpal; – … Read more
– Discussion: – view should demonstrate the metacarpals, lunate and radius aligned – hand will appear slightly palmar flexed; – w/ proper technique, the volar pisiform will lie between the distal aspect of scaphoid and the palmar aspect of the head of the capitate; – Specific Point of Evaluation: … Read more

– Discussion: – arises from anterior division of upper (C5, C6) & middle trunks (C7); – lateral pectoral nerve – musculocutaneous nerve – lateral root of the median nerve : (FCR & pronator teres) and (sensory fibers to the median nerve) – lateral cord branches … Read more
– See: Carpal Instability – Discussion: – scaphoid normally tends to flex under compressive load, and exerts a similar influence on lunate due to ligamentous attachments; – triquetrum tends to extend w/ compressive loading & will tend to move the lunate into extension; – hence lunate is in a … Read more
