origin: spinous process of C7 to T3, inferior half of ligamentum nuchae; insertion: mastoid process and lateral portion of superior nuchal line; action: acting bilaterally, extends and hyperextends the head and neck;acing unilateally, laterally flexes and rotates head and neck to the same side; nerve supply: lateral branches of the posterior … Read more
– Discussion: – tend to rotate which is poorly tolerated; – 5 deg of MCP rotation leads to > 1.5 cm of digital overlap; – Operative Treatment: – screw fixation for metacarpal frx – screw menu – when ORIF is … Read more
– Discussion: – permits the guided insertion of a cannulated blade thru the nail and into the femoral head,at one of three angles to accommodate anatomic or fracture variations; – angle options: – key onto proximal nail end, adapting the nail slot to accept the spiral blade … Read more
– Disscusion – these frx are inherently unstable, and requires internal fixation; – Percutaneous Fixation Technique: – reduction is achieved w/ a tenaculum fracture reduction clamp; – 2 or 3 0.28 inch K wires are inserted across fracture, perpendicular to long axis of phalanx & engage both cortices of the … Read more
– Discussion: – arises from thickening, contracture, and coalescence of the spiral band, Grayson’s liagment, and the lateral digital sheet; – it extends disatlly past the natatory ligament, first lying along lateral margin of the digit, but then courses toward the midline to insert into the central cord at the level of the … Read more
– Discussion: – spiral band is continuation of pretendinous cord; – at a point just distal to the superficial transverse palmar ligament (which is just proximal to the metacarpal heads), the pretendinous cord bifurcates to form the spiral bands; – spiral band passes deep to the … Read more
– See: Pagets Disease – Discussion: – Paget’s disease involves spine, esp third and fourth lumbar vertebras, in up to 1/3 of affected patients, & lower thoracic vertebras in 20%; – most patients have symptoms; – localized pain can develop because of pathologic fracture w/ vertebral collapse, spinal-canal stenosis, … Read more
