– See: Idiopathic Scoliosis: – Discussion: – bracing has been the mainstay of non operative treatment of significant curves which have a potential to progress; – progression is related to size of curve, area of spine involved, & physiologic age of child; – size of curve: … Read more
– Box Cut: – ensure that box cutting jig is placed flush on anterior and distal femoral surfaces; – box cutting jig is centered over the intercondylar notch (or IM drill hole); – if the knee has … Read more
– See: – Metacarpal Neck Frx – Metacarpal Shaft Frx – Discussion: – metacarpal neck frx involving little finger; – only collateral ligaments, remain attached to the proximal phalanx, & therefore metacarpal head is freed from any proximal stabilizing influence; – metacarpal head tilts volarly causing joint to lie in hyperextension & collateral ligaments become … Read more
See: – Thompson is especially suitable for the middle third of the radius, however, it is not suitable for distal third radial frxs because the posterolateral application of the plate may interfere w/ outcropping tendons to thumb, disturbing function; – care is taken with this approach to avoid injury to the radial nerve and therefore … Read more
– See: – Arteries of the Upper Limb; – Profunda Brachi; – Anatomy: – brachial artery originates at the lateral border of teres major muscle & courses down anterior humerus posterior to bicipital aponeurosis; – brachial artery has three main braches, of which profunda brachi … Read more

– See: Phalangeal Boutonnere Injuries – Discussion: – most common thumb deformity in RA; – results from arthritic involvement of MP joint and elongation or erosion of the attachement of the EPB tendon to the base of proximal phalanx (leading to flexion deformity); – EPL tendon & adductor expansions … Read more
– See: – Phalangeal Injuries – Rheumatoid Boutonniere – Thumb Boutonniere Injuries – Discussion: – an aquired lesion of the extensor mechanism, in which the PIP joint develops a flexion deformity and the the DIP joint develops an extension deformity; … Read more
– See: – Discussion: – refers to Boutonniere injuries more than 2 months after injury; – is difficult to treat due to shortening of: – central slip & contracture of the lateral bands; – transverse retinacular ligaments; … Read more
