Scoliosis occurs relatively frequently in the general population, and its frequency depends upon the magnitude of the curve being described. Scoliosis of greater than 25 degrees has been reported in about 1.5/1000 persons in the United States. Most curves can be treated nonoperatively if they are detected before they become...

Definition Septic arthritis is a common destructive arthropathy that requires prompt diagnosis and treatment to avoid the significant morbidity that results from the loss of a joint. Therefore, it should be strongly considered in the differential diagnosis of monoarticular disease. Diagnosis Traditionally, the diagnosis of septic arthritis was based on clinical assessment and...

Sever disease
osteochondrosis of the apophysis of the os calcis
apopohysis becomes dense and sclerotic and undergoes fragmentation
difficult to differentiate from normal finding on plain films
apophysis normally varies greatly and may ossify from several centers

juxta-epiphyseal fracture of the distal phalanx of the finger

fracture of the lateral tubercle of the posterior process of the talus

* anterior (subcoracoid)
  o humerus --> beneath coracoid process, anterior to glenoid
  o most frequent site + type of dislocation of any joint
  o easily detected
  o repeated dislocation ==> Hill-Sachs deformity and/or Bankart deformity
* posterior
  o 2 - 4% of shoulder dislocations
  o 50% d/t seizures; trauma, electrical shock
 ...

Radiology case 414-421 Clinical presentation: 76 year old lady with pain in the right shoulder and some restriction of movement.

Introduction Sickle Cell Anemia (SCA) is caused by a change in the chemical composition of the protein (hemoglobin or Hgb) that carries the oxygen inside of the red blood cells (RBC's). Normal Hgb is a round or ball-shaped folded molecule composed of 4 protein subunits - 2 alpha chains...

* symptoms: chronic ulcers, pain crises, many infections, priapism
xray findings:

  o decreased bone density in skull with widened diploic space
  o "H-shaped vertebrae" or "fish vertebrae"
  o rib notching
* thrombosis and infarction
  o AVN,...
