Data Trace Editor – See: TKR Menu / Supracondylar Femur Frx – Discussion: – known risk factors include notching of the femur, osteoporosis, and excessive polyethylene wear (w/ subsequent osteolytic defect) – other risk factors include osteonecrosis of the femur; – ref: Morphologic analysis of periprosthetic fractures after hip resurfacing arthroplasty. – Radiographs: – often oblique radiographs are needs … Read more
Discussion: – Trauma Work Up: – Assessment of Perfusion: Damage Control Orthopaedics – Preparation for Surgery – fat embolism syndrome – references: – Early unreamed intramedullary nailing of femoral fractures is safe in patients with severe thoracic trauma. – Thoracic trauma … Read more

– B agonist for Rx of Brochospasm; – 0.5-1.0 mg in 3ml NS by Nebulizer q4-6hr; – Althoughstandard dosing intervals for Beta agonists are q4-6hr,they may be given almost continuously in severe bronchospasm, as long as potential side effects are noted: (SVT, PVC, Muscle Tremors)
* Adults: Parental: 0.001-0.002 mg/kg/dose IV, may repeat in 1 to 2 hrs; 1-2 micrograms/kg/dose IM/IV: 100 micrograms = 10 mg Morphine. Pre-op: 0.005-0.01 mg/kg IM 30-60 min before surgery; Children (2-12 yrs): Parental: 0.02-0.03 mg/20-25 lbs (10 kg); * IM: onset at … Read more
– Discussion: – for iron defficiency anemia; – adult: 300mg PO qd/tid with meals; – will turn stools and urine dark; can cause GI upset; con-stipation; – sulfate form contains more elemental iron per dosage unit than gluconate (some tolerate gluconate better); – peds: prophylaxis: … Read more
– Discussion: – Dx of FES requires at least one sign from major criteria and at least four signs from the minor criteria category; – Gurd’s Major Criteria: – axillary or subconjuctival petechia – occurs transiently (4-6 hours) in 50-60 % of the cases; – hypoxemia (PaO sub 2, <60 mmHg; FiO sub 2, <= … Read more
– Discussion: – general discussion of non union / infected femoral nails – femoral shaft that has not healed in 26 wks signals a delayed union; – may be more common in segmental fractures and in winquest type IV fractures; – most common iatrogenic risk factor is failure to … Read more
– Discussion: – the two incision (“backdoor”) approach has remained the gold standard for ACL reconstruction, because it is the only technique which can reliably position the femoral tunnel at the 10 o’clock (or 2 o’clock) position (which is necessary for anatomic reconstruction); … Read more
– Discussion: – most common error is non isometric anterior tunnel placement within intercondylar notch rather than at its normal posterior insertion; – ACL graft should pull up into tibial tunnel by about 2mm with extension when fixed on femoral side; – this represents the closest reconstitution of … Read more
