One hundred and twelve shoulders with recurrent anterior dislocation
were treated with the Bristow-Latarjet procedure and had a two to five-year
follow-up after surgery. The incidence of redislocation was 6 per cent, and
an additional 7 per cent of the patients reported occasional subluxation.
In 106 shoulders, a radiographic study was carried out in order to
determine the importance of factors such as healing and position of the
transferred coracoid process with regard to the postoperative clinical
results. No redislocation or subluxation occurred in the forty patients in
whom the transplant showed osseous or fibrous union at the scapula and was
located inferior to the equator of the glenoid and less than one centimeter
medial to its rim. In shoulders in which either the transplant had migrated
more than 1.5 centimeters from that position or was placed one centimeter
or more medial to the glenoid rim, the incidence of redislocation or
subluxation was significantly increased.
