(See: Ligamentous Instability:) Discussion antatomic structures in the anterior column that resist compression forces are the vertebral body centrum and intervertebral disc; structures that counter act tensile forces in anterior motion segment are anterior longitudinal ligament and the annulus fibrosis; stable injuries to anterior column include compression frx of < 25% loss of vertebral body ht. … Read more
– See: Classification and Column Theory – Discussion: – anterior column extends from symphysis pubis & obturator foramen thru acetabulum to ASIS and up through iliac crest; – anterior column is less frequently fractured than posterior column due to frequency of posteriorly directed forces; – frxs of the anterior … Read more
– See: Anterior Approach to Cervical Spine: – Discussion: – Smith Robinson disectomy & block fusion is preferred over Cloward dowel for involvement of one or two interspaces; – for multi-level spondylosis & myelopathy, w/ more extensive anterior decompression involving excision of osteophytes & multiple vertebrectomies, a strut graft fusion … Read more
– See: – Anterolateral Approach to Forearm – Forearm Flexors – Plating Techniques – Radial Shaft Fractures: Discussion – Discussion: – anterior approach of Henry utilizes interval between brachioradialis (radial nerve) & pronator teres (or FCR distally, which are innervated by the median nerve); – … Read more
– See: Watson Jones Approach – Discussion: – Smith Petersen improved & revived the anterior iliofemoral approach; – entire ilium and hip joint can be reached thru iliac part of incision; – w/ this approach there is a need for extensive detachment of tendinous insertions & retraction of muscle, w/ potential damage to femoral artery and … Read more
PreOp Planning consider NG tube and foley catheter; have proper sized C-collar available for post operative care; position: supine w/ halter cervical traction (3-5 lbs) w/ head turned slightly to the right; consider placing a rolled towel between the shoulder blades; prep for iliac crest bone graft; hall burr is helpful for shaping bone graft; … Read more
– See: Anterior Approach to the Humerus Axillary Approach: Posterior Approach Posterior Approach to Humerus Surgical Approach for Proximal Humeral Fractures Positioning and Draping: supine or beach chair; small soft bolster is placed beneath the shoulder blades to protract the shoulder; head is stabilized to prevent hyperextension and subsequent brachial plexus palsy; place patient in … Read more
– See: – Anterior Approach to the Shoulder – Discussion: – with plate fixation of the humerus, the anterior approach is preferred for proximal and mid-diaphyseal frx w/ application of plate to anterolateral aspect of the humerus (see humeral shaft fractures); – interval lies … Read more
– Discussion: – most indicated for unstable burst frxs w/ cord impingement caused by bone fragments off the postero-superior vertebral body; – allows most direct visualization for decompression of thecal sac; – visceral and vascular structures may be injured, & this approach carries the greatest potential morbidity; – … Read more
