The concept of the study was to find the correlation between the morphometry
of the suprascapular notch and basic anthropometric measurements of the
human scapula.
The measurements of the human scapulae included: morphological length and
width, maximal width and length projection of scapular spine, length of acromion,
and maximal length of the coracoid process. The glenoid cavity was
measured in two perpendicular directions to evaluate its width and length. The
width-length scapular and glenoid cavity indexes were calculated for every
bone. In addition to standard anthropometric measurements two other measurements
were defined and evaluated for every suprascapular notch: maximal
depth (MD) and superior transverse diameter (STD).
The superior transverse suprascapular ligament was completely ossified in 7%
of cases. Ten (11.6%) scapulae had a discrete notch. In the studied material, in
21 (24.4%) scapulae the MD was longer than the STD. Two (2.3%) scapulae
had equal maximal depth and superior transverse diameter. In 47 (57.7%) scapulae
the superior transverse diameter was longer than the maximal depth. There
was no statistically significant difference between anthropometric measurements
in the group with higher MD and the group with higher STD. The maximal
depth of the suprascapular notch negatively correlated with the scapular
width-length index. The maximal depth of the scapular notch correlated with
the morphological length of the scapulae. (Folia Morphol 2011; 70, 2: 109–115
