Data Trace Editor – See: Notes for Wrightlock Spinal Fixation System: First, place the OCSTM Hook Holders on the caudal and cephalad hooks on the concave side. Next, tighten the nut on top of the hook holders using the OCSTM Hex Wrench (Figure 8). In preparation for using the OCSTM instrumentation, lubricate the Distraction with instrument milk. Position … Read more
– Discussion: – to evaluate C1 (Jefferson), Dens, superior facets of C2; – for evaluating dens fractures, body of C2, & rotary C1-C2 dislocations; – mach lines – teeth, C1 arch; – open mouth view, along w/ lateral view, will reveal fractures of the dens ; … Read more
– Dosing: – usual dose is 200 mg to 400 mg q 12 hr; – 30-40% of drug will be excreted in to urine; – there is some evidence for higher tissue concentrations than seen with other antibiotics, and with a 800 mg dose the tissue concentrations are at … Read more
– Discussion: – used in conjunction w/ a posterior approach: for fixation of condylar fractures, as well as exposure of distal humeral non unions; – olecranon osteotomy can be either non-articularl or trans-articular; – usually the non-articular olecranon osteotomy is used for non-articular condylar fractures; … Read more
– are placed on the medial (ulnar) side to avoid damaging the ulnar nerve; – elbow in 90 deg of flexion; – entry site is 1 1/2″ from the distal end of the olecranon
– See: Obstetrical Paralysis: – Discussion: – injury to the lower roots (C8 and T1 ) & or C7; – may follow forceful abduction of shoulder, produces weakness in intrinsics of hand as well as long flexors & extensors of the fingers; – these lesions are usually preganglionic; … Read more
– Discussion: – artery arises from the internal iliac artery in the pelvis; – in the pelvis, it sends a branch to the obturator internus muscle; – as vessels emerge from obturator canal, they divide into anterior and posterior branches that, instead of continuing down thigh, circle … Read more
Origin: the margin of bone immediately around the medial side of the obturator foramen, from the rami of the pubis and the inferior ramus of the ischium; Insertion: posterior aspect of the greater trochanter; Action: External Rotation of femur at the hip; (see external rotators) Synergists: Periformis, Gemellus Superior, Gemellus Inferior, Obturator … Read more
– See: External Hip Rotators; – Anatomy: – origin: inferior medial surface of the obturator foramen and the quadrilateral surface; – insertion: after passing thru the lesser sciatic notch, it inserts on the superior posterior aspect of the greater trochanter of the femur; – action: outward rotation of the … Read more
– Anatomy: – formed from anterior branches of L2, L3, L4 (see innervation of muscles of the lower limb) – largest nerve formed from anterior divisons of lumbar plexus ; – roots unite within the posterior part of psoas, & then descends thru psoas & runs downward over sacral … Read more
