Alendronate / Fosamax

– 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

Adductor Pollicis

    – 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

Acute Ligament Repair for SLD

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

ACL Graft Fixation
