Thirteen overhand-throwing athletes who failed at least 3 months of physica
l therapy white restricted from throwing and who demonstrated a positive mo
dified relocation test at 90 degrees 110 degrees and/or 120 degrees were cl
inically and arthroscopically examined. On arthroscopic examination, all pa
tients demonstrated articular surface pathology. Eleven patients had frayin
g of the undersurface of the rotator cuff, and 10 patients had fraying of t
he posterosuperior labrum. With 90 degrees shoulder abduction, 8 patients h
ad rotator cuff contact with the posterosuperior labrum. When the shoulder
was abducted to 110 degrees all patients demonstrated such contact. At 120
degrees of abduction, 12 patients revealed contact. The presence or absence
of pain during the modified relocation test correlated with the presence o
r absence of cuff contact with the posterosuperior labrum 79% of the time.
Six patients had a positive modified relocation test at all levels of abduc
tion. These patients included 2 with SLAP lesions, 1 with a Bankart lesion,
and I with a complete tear of the rotator cuff.
