Data Trace Editor – Discussion: – for short term treatment of duodenal ulcers, gastric ulcers, – provides local acid resistant barrier, inhibits pepsin; – constipation may be a frequent side effect; – may be of benefit in intubated patients – does not increase gastric pH – because of risk of aluminum toxicity, (released when compound ionizes), sucralfate is … Read more
– Precautions: – because succinylcholine causes an increase in intra gastric pressure that may lead to gastric aspiration, crycothyroid pressure should be applied; – also causes increase in intraocular pressure and in relatively contra- indicated with injuries in an open globe; – increases intracranial pressure; – Precautions w/ Spinal Cord Injury: – w/ possible cervical … Read more
Anatomy axis of femoral neck forms angle of approx 135 deg w/ femoral shaft, and is anteverted from the frontal plane by variable amount (- 4 to 36 deg, average 10 to 20 deg in Caucasians); distinct cortex surrounds the cancellous bone of the neck, the center of which becomes progressively empty with age (Ward’s triangle); center of … Read more
– See: Bone Healing w/ Plates – Discussion: – useful in subtrochanteric frxs since it permits insertion of at least two cortical screws into proximal fragment (calcar); – having multiple points of fixation above and below the fracture prevents varus or rotational migration; … Read more
– See: proximal femoral shaft fractures / – Discussion: – definition: – between lesser trochanter and 5 cm distal, even as far as center of isthmus of the femoral shaft; – technically starts below the lesser tuberosity; – medial and posteromedial cortex is a site of high compressive forces, while lateral cortex experiences high tensile stresses (forces … Read more
– Discussion: – classifaction and fracture stability – frx stability is based on presence or absence of posteromedial butress; – farther down shaft of femur primary frx is located, greater incidence of delayed union and implant failure; – forces acting on hip joint … Read more
– See: subtalar arthrodesis – Primary Fusion: – indicated for fractures w/ more than 3 parts; – restores length of gastrocnemius-soleus complex – corrects flat foot – relieves the narrow peroneal space; – in the presentation by Infante AF, et al (15th Annual Meeting of the Orthopaedic Trauma Association 1999), the authors advocate immediate subtalar … Read more
– Discussion: – arises from ascending cervical arteries – epiphyseal arterial branches form at subsynovial intra articular ring, and go on to enter the head of the femur; – disruption of this arterial ring occurs from high femoral neck frx; – these pts … Read more
– See: Rotator cuff: – Anatomy: – origin: entire anterior surface of the subscapularis fossa; – insertion: lesser tuberosity of humerus and capsule of shoulder joint; – The Subscapularis Footprint: An Anatomic Description of Its Insertion Site. – action: – main … Read more
– See: brachial plexus – Discussion: – subscapular and thoracodorsal nerves arise from posterior cord of brachial plexus while this is on costal surface of subscapularis; – both subscapular nerves usually receive fibers from C5 and C6; – upper subscapular nerve passes directly into … Read more
