– Discussion: – most common form; – distal end is located in the decussation of the FDS – small chip of bone is taken off w/ flexor tendon; – tendon retracts to level of PIP joint or distal to PIP, & long vincululm may remain intact; – a small … Read more
– PreOp Planning – most important step in reconstruction of any intra articular frx, is to expose the fracture w/o devasclarizing the fragments; – treatment plan: – open reduction; – elevation of the depressed plateau; – bone … Read more
– Discussion: – displaced, stable frx; – frx fragments are displaced > 2-3 mm, but collateral ligaments are intact; – frx may be non-comminuted (Type IIA) or comminuted (Type IIB). – no sign of subluxation; – Non Operative Treatment: – immobilized in mid flexion, these … Read more
– Discussion: – tendon retracted to the palm, held up by the lumbrical origin – tendon retracts into palm, severing all blood supply and creating extensive scarring in tendon sheath; – vincula are ruptured; – patients are tender in palm, but able to fully flex PIP joint; – location of … Read more
– Discussion: – articular fracture without significant displacement; – malleolar fractures with large plafond fragments; – these fragments are usually posterior; – posteroinferior tibiofibular ligament & deep transverse ligament are attached to the fragment; – first reduce & fix fibula; … Read more
– Discussion: – tunnel radiograph of knee provides an angled PA projection of knee; – patient is prone with the knee flexed at 40 deg; – central beam directed caudally toward the knee joint at a 40 deg angle from the vertical; … Read more
– Discussion: – turf toe is a tear of joint capsule from MT head which results in subluxation or dislocation of first MTP joint – caused by hyperextension (most common), hyperflexion, or valgus injury; – associated w/ decr ROM at first MTP joint & its sequele can include hallux … Read more
– Discussion: – most common; – occur thru base of odontoid process & may be caused by either hyper-flexion or hyperextension forces; – blood supply is often comprimised in a type 2 frx – type II frx occurs at base of dens, typically, frx plane is transverse; … Read more
– See: Collagen Discussion: – Discussion: – type I is the major collagen of tendon and bone, but it is also the predominant in lung, skin, dentin, heart valves, fascia, scar tissue, cornea, and liver; – type I collagen is essential for the tensile strength of bone; … Read more
