Purpose: Various mechanical causes which induce shoulder impingement syndrome have
been identified with the help of MRI. The aim of this study is to evaluate the incidence
of such causes.
Materials and Methods: A total of 54 patients with clinically confirmed shoulder
impingement syndrome and a normal control group(n=20) without symptoms were
included. We evaluated the incidence of hook shaped acromion, low lying acromion,
downward slope of the acromion, subacromial spur acromioclavicular joint hypertrophy,
coracoacromial ligament hypertrophy, high cuff muscle bulk, and os acromiale.
Results: Among the 54 patients, the following conditions were present: acromioclavicular
joint hypertrophy(n=36), coracoacromial ligament hypertrophy(n=20), subacromial
spur(n=18), downward sloping of the acromion(n=16), hook shaped acromion(n=11),
relatively high cuff muscle bulk(n=6), low lying acromion relative to the clavicle(n=3),
and os acromiale(n=1). In the normal control group there were nine cases of
acromioclavicular joint hypertrophy, nine of coracoacromial ligament hypertrophy, nine of
downward sloping acromion, and three of low lying acromion, but hook shaped acromion,
high cuff muscle bulk, and os acromiale were not found. Among 54 patients, the
syndrome was due to five simultancous causes in one patient, four causes in two, three
causes in 12, and one cause in 17.
Conclusion: Hook shaped acromion and subacromial spur are the statistically significant
causes of shoulder impingement syndrome. In 69% of patients, the condition was due to
more than one cause.
