– See: – Anatomic Snuff Box – First Compartment – Discussion: – a stenosing tenosynovitis of APL & EPB tendons (first compartment) at the styloid process of the radius; – inflammation causes thickening & stenosis of synovial sheath of first compartment & pain w/ … Read more
– Discussion: – deep arch is more consistent than superficial palmar arch – deep arch supplies all digits (complete) in about 97% of population; – anatomy: – large deep branch of radial artery, w/ pulsations is felt in anatomic snuff box, passes under snuff box tendons & … Read more
– Discussion: – classic delta phalanx is characterized by a triangular or trapezoidal shaped bone w/ C shaped epiphyseal plate; – proximal epiphysis curves around from its transverse orientation to a longitudinal one from proximal to distal along one side of the phalanx, thus forming a “C”‘ … Read more
– Discussion: (see osteochondral injury) – these injuries are distinct from degenerative arthritic lesions and management of these lesions should remain distinct as well; – theory is that penetration of subchondral bone causes bleeding from underlying vessels which allows clot formation in the cartilaginous defect and subsequent formation of fibrocartilage; … Read more

– See: Work Up for Scaphoid Frx – Discussion: – w/ proper casting nearly 100% of tubercle & distal third frxs will heal; – in addition to healing considerations, the surgeon should note the position of healing (malunion); – approximately 80-90% of scaphoid frx at the waist will heal, … Read more
– Casting Technique: assistance provided by Jorge Garcia.
– Indication for Closed Treatment: – indications — These are based on “personality” of the fracture as described by Nicoll EA (1964) – he listed factors favoring union: – displacement: if the fracture fragments on are or can be opposed to 25% in a transverse fracture, casting or bracing is permissible – more than 50% initial frx … Read more
