Data Trace Editor – Anatomy: – origin: anterior surface of sacrum between and lateral to anterior sacral foramen, capsule of sacroiliac articulation, margin of the greater sciatic foramen, and sacrotuberous ligament; – insertion: superior border of greater trochanter of femur; – action: external rotation of hip & … Read more
– See: – Penicillin Family – AntiPseudomonal Agents – Discussion: – piperazine penicillin derivative with increased activity against many gm negative bacteria – P.aeruginosa, Enterobacteriacae – S.faecalis; Anaerobes (B.fragilis); – for serious infect.: 200-300 mg/kg/24hr IV in 4-6 divided doses; – for complicated … Read more
– Discussion: – flexion contractures of PIP joint are more difficult to correct; – flexion deformities of PIP joint may be caused by contracture of a diseased central cord (which is an extension of palmar pre-tendinous cord); – PIP join contracture may be presaged by development of firm, fixed … Read more
– See: Class II Agents – Discussion: – non selective B1 and B2 blocker; – used to treate HTN
– Discussion: – incorrect placement of pins is a common error; – superior quadrant of femoral head should be avoided: – this is where retinacular vessels enter, and pin penetration into this area may cause AVN; – pins should not be placed superiorly … Read more
– Discussion: – if the tourniquet is used, then it should be left elevated until wound closure is complete (expect wound swelling as soon as the tourniquet is released); – if swelling prevents tension free wound closure, anterior wound may be left open for DPC in 3-5 days when swelling subsides; … Read more
– Discussion: (see pilon frx discussion) – fibula is usually fractured above the joint line; – some authors will avoid ORIF of the fibula in these injuries if there is excessive fibular comminution (ie poor chance of good fixation) and if there is excessive varus of the articular surface (ORIF would accentuate the varus); … Read more
– Restoration of Length: – may be obtained w/ use of femoral distractor or external fixator placed in distal 1/3 of the tibia and the talus or calcaneus; – two pins are placed perpendicular to the anatomic axis and therefore parallel with the joint surfaces of the tibia; – … Read more
– See: Pilon Frx Menu – External Fixation: – external fixation applied medially and across the ankle can protect the articular reconstruction and prevent collapse; – external fixation across the ankle can restore length (thru distraction) w/ or w/o fibular fixation; – Technique of External Fixation … Read more
– Discussion: – demonstrates lateral masses (pillars) – pillar frx is usually visible in inferior articulating facet of involved mass; – pillar frx is usually visible in the appropriate oblique projection; – however, it may not be apparent in oblique projection if fragments are neither … Read more
