Data Trace Editor origin: superior borders of the angles of lower 6 ribs medial to the tendons of insertion of the Iliocostalis Lumborum; insertion: into the angles of the upper 6 or 7 ribs and into the transverse process of the 7th cervical vertebrae; action: acting bilaterally, extension and hyperextension of the spine; acting unilaterally, laterally flexes the spine; … Read more
– Discussion: – approach is similar to Smith Peterson; – provides exposure to the outer aspect of the iliac bone and gives exposure of the anterior and posterior columns; – extended iliofemoral approach provides best access to both column fractures (esp w/ greater sciatic notch involvement) & allows best … Read more
– Discussion: – arises from T12 & L1; – emerges from lateral border of Psoas & passes over Quadratus Lumborum to penetrate transverse abdominal muscle near the iliac crest; – nerve supplies anterior cutaneous branch to skin of suprapubic region
– Discussion: – before retractors are placed beneath coracoid process palpate for musculocutaneous nerve as it enters conjoined tendon; – nerve lies on deep surface of coracoid muscles; – most often nerve enters coracobrachialis and biceps from medial aspect about 5 cm distal to tip of coracoid process; … Read more
– See: Aortic Stenosis – Etiology: (familial inheritance) – no anatomic stenosis – anterior leaf of MV moves against Hypertrophied septum, blocking outflow; – Sequelae: – sudden death is common; – L.V.H. – mitral valve dysfunction. – Physical Exam: – pulse collapses w/ … Read more
– Discussion: – prevalence of scoliosis: – 10 deg curve is considered to be the threshold for scoliosis; – curves > 10 deg occur in 2.5/100; – curves > 20 deg occur in about 1/2500 … Read more
– See: Musculoskeletal Considerations in Pregancy – Discussion: – uncommon disease which is a diagnosis of exclusion; – most often seen in women during the third trimester of pregnancy and in middle-aged men; – typically there is no antecendent trauma; – up to 40% of patients may … Read more
– See: Sacro-Iliac Fracture Dislocations – Management: – consider direct frx fixation from iliac crest into sacrum; – under x-ray control, long, 6.5-mm cannulated lag screws transfix the frx from iliac wing to body of S-1; – because of risk to neural structures, K guide wire usually is inserted, and its … Read more
Origin: superior 2/3 of the iliac fossa, internal border iliac crest, anterior sacroiliac, lumbosacral and iliolumbar ligaments, ala sacrum; Insertion: Lesser trochanter of femur and for a short distance below along medial border of the shaft; Action: Flexes thigh at the hip, minimal activity on lateral rotation of the thigh; Reversed origin-insertion action: when the … Read more
origin: superior borders of the angles of the 3rd to 6th ribs; insertion: the posterior tubercles of the transverse processes of the 4th, 5th, and 6th cervical vertebrae; action: acting bilaterally, extends and hyperextends the vertebral column; nerve supply: posterior rami of the spinal nerve, C6, C7, C8 ; synergists: splenius cervicis, Semispinalis Cervicis Longissimus Cervicis
