Scoliosis screening device

The method of measuring the angle of trunk rotation in a patient comprising:

• having said patient bend forward to expose the apex of maximum deformity, viewed at eye level from behind the patient,
• laying across the apex of the deformity, substantially perpendicular to the long axis of the body, and reading the angle of rotation directly from, a device comprising:
• a backing plate having a U-shaped groove therein and an edge which contacts said patient during measurement, the U opening away from said edge of said plate which contacts said patient during treatment,
• a transparent U-tube affixed to said backing plate in said groove,
• said tube being filled with a fluid and containing a ball indicator,
• said edge of said plate which contacts the patient being generally straight and having a generally semi-circular indentation therein to accomodate the spinal column of the patient,
• said plate having indicia thereon to indicate the angle of trunk rotation, said angle being shown by the position of the ball indicator in said U-tube,
• whereby, when placed on said patient's back, the angle of trunk rotation is read directly in a single procedure, said indentation providing means for avoiding interference in such measurement by the patient's spinal column.
