– See: Knee Joint Menu – Patient Positioning and Preparation: – positioning: – opposite limb is well padded to prevent potential pressure problems; – operative thigh is placed against an arthroscopy post or is placed in a circular thigh immobilizer; … Read more
– Surgical Considerations for Specific Diseases and Conditions: – Medical Assesment: – surgical risk assessment – risk factors for infection: are taken into consideration; – anesthesia consult and posting – anesthesia, medical consderations, and timing for … Read more
– Discussion: – arises from thickening and contracture of pretendinous bands: – inserts into skin distal to MP joint & into tendon sheath does not cause N/V displacement, but is responsible for MP flexion deformities which can be predictably corrected by surgical excision; – at a point just distal … Read more
– Discussion: – preganglionic lesions represent root avulsions from the spinal cord; – 2 catagories: – central avulsions: nervs are avulsed directly from the spinal cord; – intradural ruptures: rootlets are ruptured proximal to the dorsal root ganglion; – preganglionic injuries … Read more
– Discussion: – is apparent when with stress testing lateral tibial plateau rotates posteriorly in relation to the femur with lateral opening of joint; – atraumatic type: – presents as chronic laxity, often with a varus knee deformity; – this ligamentous laxity often … Read more
– Discussion: – most indicated for unstable burst frx w/ cord impingement along w/dural tear and nerve root entrapment from frx of posterior elements; – most effective at the thoracolumbar junction and in the lumbar spine as more direct means of reducing the bony fragments; – procedure involves hemilaminectomy and … Read more
– Anatomy: – anterior compartment – lateral compartment – deep posterior compartment – superfical posterior – Anatomy: – position: either prone or on side, with the affected extremity uppermost; – incision: – incision is made just posterior to the … Read more
– See: Anterior Tibial Artery – Discussion: – posterior tibial artery enters posterior compartment of leg lying posterior to tibialis posterior & enters plantar foot after passing behind medial malleolus; – largest branch is peroneal artery arising high in leg and coursing downward in posterior compartment, lying just medial to fibula; – gives off branches to … Read more
– See: Lateral Approach – Discussion: – allows exposure of the entire distal humerus as well as radial head, radial neck, and biceps tuberosity; – indications for this approach include frxs of distal humerus, old posterior elbow dislocations, radial head frx, radial head excisions, arthroplasties, fixation of distal biceps tendon rupture, and … Read more
– See: PIN – Inciting causes: – radiocapitellar joint ganglions and synovitis – congenital tightness of ligamentous arcade of Frohse; – include poorly placed screws for fracture fixation – PIN is vulnerable during ORIF of proximal radius; – in 25% … Read more
