– Discussion: (see bisphosphonates) – type of aminobisphosphonate (a synthetic analogs of pyrophosphate) which acts as an inhibitor of osteoclast-mediated bone resorption; – due to substantial reduction in bone resorption, bone formation exceeds bone resorption at these remodeling sites, which leads to progressive gains in bone mass; – this … Read more
– Discussion: – adductor pollicis consists of 2 parts, one of which is transverse & other oblique; – transverse head attaches to the volar crest of the 3rd metacarpal; – oblique head attaches to ligaments around capitate, trapezium, and covering of the FCR; – heads … Read more
by William Mallon MD – Skin Incision: – Identification of Radial Nerve: – Identification of 3-4 Interval: – Longitudinal Arthrotomy: – arthrotomy performed just distal to Lister’s tubercle over scapholunate interval; – this should provide clear exposure of scaphoid and lunate; – alternatively, a distally based capsular flap can be … Read more
– Discussion: – see Arthrex, Mitek, Linvatec, Smith-Nephew – in choosing a fixation technqiue consider the need for the following: – circumferential (360 deg) healing of graft against tunnel wall (interference screws do not permit this); – bioabsorbable material … Read more
Discussion AC joint is situated between the clavicle and acromion; acromion has two ossification centers which fuse at age 22 yrs; it permits motion in three planes: AP gliding of acromion during protraction & retraction of scapula; tilting of acromion during abduction & adduction of arm; rotation of the clavicle; rotation occurs during abduction & … Read more
used to evaluate the extent of ligament injury to the A-C joint Technique patient is erect; 10 to 20 pound wts (depending on patient size) are looped over the patient’s wrists suspending them from the wrists; these are not to be griped by the patient, as the act of gripping may tense the shoulder muscles … Read more
