impingement study was inconclusive in five patients, impingement was present in four patients and absent in 26 patients.
We excluded spaces such as the subdeltoid/subacromial bursa and subcoracoid
bursa, which would have other clinical ramifications.
Of 32 cases of chronic shoulder dislocation3 all were unilateral (31 anterior subcoracoid
and 1 posterior) dislocations.
A thickened CHL and joint capsule, decreased axillary recess volume and obliteration of the subcoracoid
fat triangle was used for presumptive MR arthrographic diagnosis of adhesive capsulitis (3,8).
Similar differential testing is possible for pain on resisted medial rotation, to determine whether the tendons of subscapularis and long head of biceps (LHB) or other adjacent structures are impinged within the subcoracoid
The subdeltoid bursa (SDB) and subcoracoid
bursa (SCB) were scanned with the shoulder in a neutral position, whereas the subacromial bursa (SAB) was scanned with the shoulder in a modified Crass position.
Humeral heads were palpable anteriorly in the subcoracoid
dislocation of the lateral end of the clavicle.
(3) The second site is behind the clavicle in the costoclavicular space, while the third site is at the subcoracoid
space in the angle between the pectoralis minor tendon and where it attaches to the coracoid process.
The glenohumeral crease is palpated to identify a subcoracoid
window to enter the joint space.

impingement syndrome," International Orthopaedics, vol.
Type VI: This rare injury involves inferior displacement of the clavicle either subacromial or subcoracoid
behind the conjoined tendon.
