– 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
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
– 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
– Discussion: – it is essential to locate axillary nerve when performing any anterior shoulder reconstruction; – to facilitate nerve identification, place arm in adduction & in neutral rotation; – pass a finger along lower aspect of subscapularis, inorder to palpate nerve as it passes medially along subscapularis to … Read more
– Discussion: – physical properties – state in body fluids – calcium is a necessary & important addition to cell membranes, giving strength to these structures and regulating permeability; – physiologic roles of calcium are well established; – abnormally … Read more

– See: Humeral Frx – Main Menu – Condylar Fractures – Non Union of Humeral Fractures – Pediatric Humeral Shaft Fracture – Synthes Humeral Shaft Products – Discussion: – mechanism: – bending force produces transverse frx of the shaft; – torsion force will result in a spiral fracture; – combination of bending and torsion produce … Read more
– See: – Proximal Humeral Physeal Injuries – Condylar Fractures – Discussion: – while radial nerve paralysis occurs in adults, its rare in children; – most represent neuorpraxias, & are expected to return w/ in 3-4 months; – acceptable reduction: – overriding of 1 to 1.5 cm is accepted, as overgrowth is common in pediatric … Read more
