– See: Reconstructive Foot Surgery – Discussion: – is used for coverage of distal tibia and ankle; – during dissection paratendon is left over the extensor tendon, allowing donor site to do welll, with skin graft; – to avoid devascularizing foot, the posterior tibial artery must be intact
– many techniques described with one or two tibial and one or two femoral tunnels – much biomechanical data confirms that both bundles are necessary to restore – ACL function – main findings are that PL bundle contributes to rotational stability closer to full extension – Distribution of in situ forces in the anterior … Read more
– See Compartments: I, II, III, IV, V,VI and approach to the distal radius; – Technique: – straight dorsal incision centered over the wrist; – because the skin is loose over the dorsum of the wrist, contractures are uncommon; – incise skin and subcutaneous tissue down to the retinaculum; – careful to preserve dorsal veins and … Read more
– Discussion: – dorsal rim frxs usually result from a fall on the outstretched hand; – proximal carpal row impacts against the dorsal lip of the articular surface of the radius, which fracture in compression and displaces proximally and dorsally; – volar radiocarpal ligaments fail in tension, and dorsal … Read more
– Discussion: – distal radius fracture w/ dislocation of radiocarpal joint; – most common frx dislocation of the wrist joint; – comminuted frx of distal radius may involve either anterior or posterior cortex and may extend into the wrist joint; – frx dislocation or subluxation … Read more
– See: – Differential Dx of PIP Injuries – Fracture Dislocations of the PIP Joint – Phalangeal Injury – Discussion: – anatomy of the injury: – volar plate is always detached (usually from middle phalanx) in PIP dorsal dislocations; … Read more
– See: – Dorsal Dislocation of PIP joint – Extension Block Casting – Phalangeal Injury – Discussion: – long moment arm of the PIP joint, places this joint for higher risk of this injury; – mechanism and anatomy of injury: … Read more
– See: – Carpal Instability – Kinematics of the Wrist – Discussion: – lunate will tend to flex w/ loss of ulnar ligamentous support from the triquetrum; – lunate extends when there is loss of radial ligamentous stability; – DISI may arise as a result of: – scaphoid frx; – scapho-lunate dissociation; – perilunate dislocation … Read more
– See: – Plating Techniques – Radial Shaft Fractures: Discussion – Discussion: – dorsolateral approach is best suited to frxs of proximal & middle thirds of radius as well as to address injury to proximal RU joint; – advantages: – … Read more
– Discussion: – w/ arm in external rotation, upper & lower borders of subscapularis can be visualized and palpated; – rotator cuff interval (soft spot) between supraspinatus & subscapularis is identified; – subscapularis tendon is tagged just shy of insertion; – subscapularis tendon and subajacent capsule are … Read more
