Joseph Risser

from Wikipedia, the free encyclopedia

Joseph Ch. Risser (born August 6, 1892 in Des Moines , Iowa , † March 11, 1982 in Pasadena , California ) was an American surgeon.

This doctor has made a name for himself in the treatment of curvature of the spine ( scoliosis ). The redressing Risser plaster goes back to him, which works with pads on the lumbar bulge and rib hump to correct the curvature of the spine. This plaster of paris is placed in a "Risser frame", a 2 m long and 1 m high and wide tubular steel frame in which the patient is suspended while the plaster is being applied.

Risser sign

The Risser sign named after him evaluates the ossification of the apophysis on the iliac crest . There is a clue for the expected malleability of the spine and the expected growth , see also determination of bone age .

It is divided into six stages:

  • Crack 0: iliac crest apophysis not yet ossified
  • Crack I: apophysis on the outer edge of the iliac blade
  • Crack II: apophysis half of the iliac blade
  • Crack III: apophysis 3/4 of the iliac blade
  • Risser IV: apophysis delineated along the entire iliac blade
  • Risser V: Apophysis completely ossified, no longer definable
