05004 - TRUNK ASYMMETRY INDICATOR
8.1
INTENDED USE AND DESCRIPTION
Instrument composed of an orthopedic technician caliber,
with a plumb line applied on a sliding guide. The
combination of these two elements makes it possible to
describe the trunk asymmetries in quantitative terms.
8.2
MATERIALS
PMMA.
8.3
PACKAGE CONTENT
Trunk indicator, 1pc
Plombe line, 1pc
8.4
SETUP AND USE
To measure the offset of a column point from a midline - for
example the line interglutea - the following procedure must
be followed:
.1
Position the caliper on the patient's body at the
height of the point of the column to be evaluated
.2
Adjust the plumb line so that it passes through the
medial reference (intergluteal line or support base)
.3
Read the value of the size of the caliber and
calculate that of the shortest segment
.4
Based on the measurements just taken, use the
attached table which will provide the percentage
of translation of the anatomical part of interest

Corazza’s torsion meter is a manual tool for the
assessment of the degree of rotation of the trunk in
standing position.

SETUP AND USE
The assessment of a subject with suspected scoliosis is
carried out in a stand-up position.
The base of the instrument is placed near the sacred; in this
way zero reference plane is defined, with respect to which
the alignment of the trunk on the transverse plane at the
desired level will be read. When the mobile element is in
turn approached to the back, it will slip in its housing by a
number of degrees corresponding to the rotation of the
trunk. An index on the housing accurately indicates the
degrees of rotation.
The tool is suitable for a diversified use:
•
in stand-up position, it accurately identifies a rotation
of the trunk, one of the most sensitive clinical signs for
identifying true scoliosis;
•
we can compare the rotation in static with the
rotation in anteroflexion (scoliometer, inclinometer),
data not always superimposable and in turn
correlated, but inaccurately, with the vertebral torsion
measured on the radiograph;
•
in orthostatism or even seated we can verify the
possible change of rotation with a stretching exercise
(information on defect reducibility);
•
with a stabilized pelvis (preferably sitting) we can
evaluate the excursion of the trunk in an active
rotation movement (range and symmetry).
