Geometric Morphology of the Coracoacromial Ligament: A Cadaveric Study

Table 2

The mean thickness measurements (mm) of acromial insertions according to CAL types.

	Y-shaped	Broad-banded	Quadrangular	V-shaped	Multiple-banded	Total	p
	n=9	n=12	n=9	n=24	n=6	n=60
LSTAI							p<0.001
MSTAI							p<0.001

LSTAI: lateral side thickness of acromial insertion; MSTAI: medial side thickness of acromial insertion.
Data are reported as mean ± SD. ANOVA; α: 0.05; independent t test; difference is statistically significant; post hoc; Tukey HSD test, Tamhane T2 test.
Difference with Y-shaped is statistically significant.
Difference with broad-banded is statistically significant.
Difference with quadrangular is statistically significant.
Difference with V-shaped is statistically significant.
Difference with multiple-banded is statistically significant.
