Data Trace Editor Type I: Open, exposed bone without evidence of osseous infection but with evidence of soft tissue infection; Type II: Circumferential, cortical, and endosteal infection; x-ray showing a diffuse inflammatory reaction, increased density, and spindle shaped sclerotic thickening of the cortex in addition to areas of bone resorption; often an involucrum surrounding a sequestrum; Type III: … Read more
– See: – Radiographic Studies – Verticle Fractures of Medial Malleolus – Discussion: – transverse frx of fibula occuring below syndesmosis; – usually there is enough remaining butress of fibula to prevent lateral talar tilt or displacement; – avulsion frx of distal fibula c/w supination/adduction frx; – … Read more
– Discussion: – Weber C ankle fractures occur above the the syndesmosis and are similar to PER injuries in the Lauge Hansen classification: – classification: – C: fibula fracture above syndesmosis – C1 diaphyseal fracture of the fibula, simple … Read more
– See: – Stance – Muscle Activity During Gait – Discussion: – during last portion of single limb stance & entirety of wt release, tibial external rotation continues, ankle plantar flexion is seen, and sub- talar joint continues to invert; – forefoot is now in a … Read more
– Discussion: – see: stability of weber b fractures: – isolated Weber B fractures (no medial injury) can be treated w/ a cast if there is upto 3 mm of fibular displacement; – it has been observed that x-rays tend to over-estimate displacement (as compared to … Read more
– Discussion: – this manuever helps diagnose SLD but the test is not specific for SLD, because it may reposition entire proximal carpal row if row, rather than the scaphoid; – manipulation of scaphoid by examiner may reproduce pt’s sensation of instability or even cause subluxation of proximal pole of the scaphoid; … Read more
– Contraindications same as Heparin: – ASA (Bleeding) – w/ hemorrhagic tendencies – pregnancy – severe hepatic or renal disease – severe hypertension – blood dyscrasis – Agents which Increase Prothrombin Time: – Acetaminophren; – Allopurinol – ASA – Steroids – Cimetidine – Indomethacin – Flaggyl – Hypoglycemics – Phenothiazines – Phenylbutazone – Propylthiouracil – … Read more
– microvascular thrombotic process which results in skin necrosis; – occurs in patients with partial deficiency of protein C within the 1st 1-2 days of warfarin therapy
– Discussion: – Medial cortical overlap technique; – Kaufer H, et. al. (1974); – Stover, et al. (1971) – For unstable intertroch frxs w/ sl medial or posterior instability; – Reduction w/o medical cortical apposition or overlap is unstable & will result in femoral neck shortening and … Read more
Action inhibits Vit K dependent production of clotting factors mainly inhibits prothrombin (II) and VII but also IX and X VII (t/2=4-6hrs), IX (t/2=18-24hrs), X (t/2=18-24hrs), II (t/2=18-24) proteins C (t/2=6 hrs) and S (early); hence PT increases in 48 hrs 2nd to decr of VII but many days of therapy needed for therapuetic levels … Read more
