See also: X-rays for THR X-rays for Femoral Neck Fractures Discussion this view should demonstrate the iliac bone, sacrum, pubis, ischium, femoral heads and necks, and greater or lesser trochanters; arcuate, iliopubic, ilioischial, and acetabular teardrop lines, sacral foramina, & SI joint should be scrutinized carefully and identified in a systematic manner; patient is supine with the … Read more

AP View of the Wrist

– See: – PA View – Radial Inclination – Discussion: – AP has the dorsum of the hand touching the film, with the x-ray beam passing palmar to dorsal, whereas in a PA film, the palmar surface lies flat on the film and the x-ray beam passes from the dorsal to palmar surface; – palmar … Read more

APC-I

– Discussion:     – anterior SI ligaments are stretched;     – radiographs show slight (< 2 cm) widening of the pubic symphysis and often imperceptable widening of the SI joint;     – results from low energy forces Surgeon Variability in the Treatment of Pelvic Ring Injuries Stress radiograph to detect true extent of … Read more

AO/ASIF Femoral Distractor

Indications allows unobstructed view of articular surface of acetabulum; Technique proximal bolt is inserted in the iliac wing in its superior portion, just distal to thickened crest; proximal bolt must pass through portion of ilium in continuity w/ sacrum (or frx proximal to this point must be stabilized) prior to application of a distraction force; distal bolt … Read more

AO Classification (Muller)

– A: Extra-articular (Transverse) – B: Unicondylar fracture        – subdivided into lateral condyle sagittal, and medial condyle saggital and coronal;        – deforming forces: gastrocnemius        – of special importance is B III (Coronal or Hoffa fracture), where only soft tissue attachment is the posterior capsule, that behaves  … Read more

AO/Weber: Type A Malleolar Fractures

– Discussion:     – usually involves a supination-adduction injury;     – frequently does well w/ closed reduction;     – if frx in fibula is transverse, it is type I avulsion fibular frx;     – since syndesmotic ligaments are intact, ankle mortise is also stable;     – type A:  fibula fracture … Read more

Aortic Stenosis

  – See: IHSS – Etiology: Congenital, Rheumatic Hrt, or Bicuspid valve (pts > 60 yrs); * Classic symptoms: – Angina : – Syncope : – CHF (poor prognosis & high mortality)    

AP of Ankle

  – Discussion: – is taken in line with the long axis of the foot; – entire fibula should be included if there is lateral joint tenderness above the joint line; – this view is used to evaluate medial & lateral malleolus anterolateral tibia and proximal fibula; – osteochondral frx of distal tibia and talus; … Read more
