Measurements of the distance between the coracoid and clavicle, and quantitative analysis of the ACJD classification.

	Mean ACJD measurement, in mm	ACJD III	ACJD V
Group I	19.1	3	9
Group II	19.1	4	7
Group III	20.2	3	4
Group IV	17.9	3	3
p-Value between I and II	0.86	–a	–
p-Value between I and III	0.97	–	–
p-Value between I and IV	0.96	–	–

^aAs this is a score presenting non-normal distribution, it was not possible to use the t-test to calculate the p-value.
