– Discusison: – not to be confused w/ pyogenic granuloma – poorly understood papulovesicular skin disorder involving ulcerations and necrosis which usually occurs along w/ an underlying systemic disease; – concomitant ulcerative colitis occurs in 30 – 60% of infected patients; – other … Read more
– Discusison: – lesion should not be confused ith pyoderma gangrenosum; – it is not primarily a true infection; – an acquired vascular lesion lesion which may follow a laceration or skin puncture; – lesions may be found in oral mucosa and in the hands; … Read more
– Puncture of Shoulder Joint: – posterior approach gives easy access to glenohumeral joint & avoids risk of damaging brachial plexus or cephalic vein; – pt should be seated & entire shoulder, both anterior & posterior, should be prepped and draped; – palpate most lateral edge of the acromion … Read more
-See: – Hypoparathyroidism: – Actions of PTH: – Discussion: – lack of responsiveness to PTH due to defect in adenyl cyclase; – clinical picture may resemble of hypoparathyroidism; – due to inability of bone & kidney to respond to parathyroid hormone, hypocalcemia and hyperphosphatemia occur in … Read more
– Discussion: – coverts a complex link joint to a simple hinge by creating a radiocarpal articulation; – motion between the radius and capitate is both translational and rotational, which has the effect of dissipating forces on the radius; – expect 60-80% of contralateral motion (w/ about an 80% flexion-extension arc); – expect preservation of … Read more
– Discussion: – function of the PTFJ – accept 1/6 the axial load of the leg – resist torsional stresses originating from the ankle – resist tensile forces created with weight bearing – resists lateral bending forces – subluxation is common in preadolescent … Read more
– See: Phalangeal Injury Menu: – Discussion: – fractures of the proximal phalanx are potentially the most disabling fractures in the hand; – direct blows tend to cause transverse or comminuted frx, where as twisting injury may cause oblique or spiral fracture; – proximal fragments are usually flexed by intrinsics while distal fragments … Read more
– See: proximal phalangeal fractures: – Disscusion – indicated for unstable frx of base, shaft, and neck; – K wire characteristics: – use 0.035 or 0.045 inch wires, depending on the size of the phalanx – holding power of the wires: … Read more
– See: – Subtrochanteric Fractures – Discussion: – failure of nail to fill IM canal of either the proximal or distal fragment, may lead to postoperative instability; – tend to migrate into a varus deformity – requires abduction and traction for reduction; – tends to have an accentuated anterior bow; – internal rotation tends to … Read more
– See: Technique of Free Tendon Grafting – Discussion: – prosthetic graft serves as temporary spacer around which a pseudotendon sheath forms, & provides a healthy bed in which to place tendon autograft; – pulleys can be reconstructed at time of insertion of prosthesis – … Read more
