Περίληψη:
The present study proposes a simple and reproducible method to classify
the morphology of the suprascapular notch (SSN), on the basis of
specific geometrical parameters that clearly distinguish one type from
another. Four hundred twenty-three dried scapulas from the Department of
Anatomy in the University of Cologne, Germany, were examined. Five types
of SSN were observed: type I, without a discrete notch, 35 (8.3%); type
II, a notch that was longest in its transverse diameter,. 177 (41.85%);
type. III, a notch that was longest in its vertical diameter, 177
(41.85%); type IV, a bony foramen, 31 (7.3%); type V, a notch and a
bony foramen, 3 (0.7%). For the vertical diameter, we took the maximal
diameter of the notch perpendicular to the imaginary line that joins the
two superior corners of the notch. For the transverse diameter, we took
the diameter perpendicular to the midpoint of the vertical diameter.
This classification based on the vertical and the transverse diameters
of the SSN suggested a clear distinction of the notch types. This simple
classification included all the anatomical variations of the SSN. Using
this method, the clinician will be able to define easily and quickly the
notch type on a plain radiograph, and perhaps be able to correlate
suprascapular nerve entrapment with a specific type of SSN.
