During the past several decades, the treatment of anterior shoulder in
stability has evolved substantially, Treatment initially was based on
conservative management with rehabilitation protocols for shoulder gir
dle strengthening, Functionally disabling instability and recurrent di
slocation precluded the acceptance of conservative management as the d
efinitive treatment for all patients, Attention then was turned to ope
n repair strategies, Despite generally positive results, a significant
number of complications became evident, With time, however, technique
s improved and surgical complications were lessened, As shoulder arthr
oscopy was more widely practiced, the surgical reconstruction of insta
bility became significantly less invasive, A high learning curve has b
een associated with the new arthroscopic techniques, and higher redisl
ocation rates than those of open procedures have limited their accepta
nce by many orthopaedic surgeons, This review article examines the ana
tomy and pathology of anterior shoulder dislocations, and critically r
eviews the actual laboratory and clinical data supporting use of these
various treatment options, Only through careful examination of well-c
ontrolled scientific studies can clinicians devise their own treatment
protocol for symptomatic anterior instability of the shoulder.
