Data Trace Editor – Discussion: – From Hippocrates to the Eskimo – a history of techniques used to reduce anterior dislocation of the shoulder. – w/ a witnessed dislocation, consider immediate relocation on field; – this consists of initial slight abduction and internal derotation of affected arm; – this can be done … Read more
– Discussion: – treatment of jump locked or perched facets is reduction by halo traction and then placement of a halo jacket; – closed reduction usually succeeds; – Diff Dx: – prior to attempted reduction ensure that the diagnosis is correct; – the differential diagnosis should include pure … Read more
– See: – Proximal Frx – Distal Frx – Rotational Alignment – Deforming Forces: – muscular forces deform the femur after fracture; – abductor muscles: – abducts proximal femur following subtrochanteric & high proximal shaft fractures; – psoas: – proximal 1/3 frx of shaft are also … Read more
– Considerations: – anesthetic considerations: – generally GEA is the standard of care: – some anesthesiologists state that there is no such thing as safe pediatric conscious sedation; – hematoma block may be dangerous and is usually ineffective; … Read more
– Radiographs: – rarely long posterior spike of distal fragment is comminuted; – Fracture Characteristics: – w/ supination external rotation frx, spiral oblique frx usually begins in almost transverse plane distally on anterior surface of the fibula at or just above level of plafond; – it spirals externally, w/ frx exiting … Read more
– Discussion: – impediments to reduction: – incarcerated bony fragments which remain attached to lisfranc ligament; – entrapped anterior tibial tendon may occur in the case of a laterally dislocated first metatarsal (homolateral); – key to reduction: … Read more
origin: anterior surface of the lateral mass of the atlas and the root of its transverse process; insertion: the inferior surface of the occipital bone anterior to the foreamen magnum; action: aids in flexion of the head and the neck; nerve supply: C1, C2; synergists: Sternocleidomastoid, Longus Colli, Longus Capitis
– See Quads – Origin: – Straight Head: Anterior Inferior Iliac Spine – Reflected Head: Groove on upper brim of acetabulum; – Insertion: Upper border of patella by the ligamentum patella into tibia tuberosity; – Reversed origin-insertion action: Flexes the pelvis on the femur and gives anterior stabilization to the pelvis; … Read more
– Discussion: – normally separates from the anterior tibial artery as it perforates the interosseous foramen; – this branch heads superiorly and in the direction of patellar tendon, supplying the skin overlying patellar tendon, – supplies the anterior aspect of the knee, the superior tibiofibular joint, and the lateral condyle of the … Read more
– See: anterior instability – Discussion: – characterized by dislocation occuring after minor trauma, relative ease of relocation, and evidence of multidirectional instability; – this condition is often present in overhead throwing athletes; – it may lead to thoracic outlet syndrome (dead arm syndrome); – causes: … Read more
