Data Trace Editor origin: anterior surface of the lateral mass of the atlas and the root of its transverse process; insertion: the inferior surface of the occipital bone anterior to the foreamen magnum; action: aids in flexion of the head and the neck; nerve supply: C1, C2; synergists: Sternocleidomastoid, Longus Colli, Longus Capitis
origin: anterior surface of the lateral mass of the atlas and the root of its transverse process; insertion: the inferior surface of the occipital bone anterior to the foreamen magnum; action: aids in flexion of the head and the neck; nerve supply: C1, C2; synergists: Sternocleidomastoid, Longus Colli, Longus Capitis
origin: from the lateral process of the axis; insertion: the lateral part of the inferior nuchal line of the occipital bone and the surface of the bone immediately inferior to the line; action: extends the head and rotates it to the same side; nerve supply: a branch of the dorsal ramus of the suboccipital nerve; synergists: Rectus Capitis … Read more
– origin: superior surfaces of the transverse processes of the atlas; – insertion: inferior surface of the jugular process of the occipital bone; – action: aids in lateral flexion of the head on the neck; – nerve supply: C1, C2; – synergists: Longus Capitis, Longissimus Capitis, Semispinalis capitis
– origin: the tubercle on the posterior arch of the atlas; – insertion: the medial part of the inferior nuchal line of the occipital bone and the surface between it and the foramen magnum; – action: extends the head at the neck; – nerve supply: a branch of the dorsal primary division of the suboccipital nerve; … Read more
– Rates of 8-12 are appropriate for adults; – 20-25 for newborns – 15-20 for small children. – w/ high pCO2: must increase @TechImPOxGna[Minute Vol; (always ensure that ventilator is functioning properly, esp check for a leak around the cuff of the endotracheal tube or in ventilatory tube, or connections, or if the endotracheal tube … Read more
– Discussion: – effect on tibial bone supply: (see blood supply to the tibia) – unreamed nails theoretically minimizes disruption of the endosteal vasculature; – references: – Early changes in nutrient artery blood flow following … Read more
– Discussion: – these plates are used with 3.5 mm cortex screws; – their main application is for use with pelvic and acetabular frx; – they may be also used in fractures of the distal humerus (dorsolateral apect), the clavicle, and the calcaneus; – reconstruction plates have notches … Read more
– See: – Arteriography, Microanastomosis, Pharmocological Agents in Vascular Surgery – Vaccum Assisted Wound Closure Device – Discussion: – w/ severe extremity wounds, early radical debridement combined with early soft tissue coverage (regional or free flap) will decrease wound infection, flap loss, & delayed bone healing; – early coverage … Read more
– Discussion: – specially designed to be bent and twisted in two dimensions; – hence they are useful for the pelvis; – already low strength of the plate is further diminshed by three dimensinal bending; – bending angles greater than 15 deg at any one site must be … Read more
