The Bristow procedure was originally described by Helfet in 1958, describing it after his mentor - Walter Rowley Bristow.
The procedure involves transferring the tip of the coracoid with the conjoined tenon under the subscapularis, so that it acts as an anterior stabiliser. In the original procedure the conjoined tendon was sutured to the subscapularis muscle, but later modifications involved fixing the coracoid tip to the anterior glenoid with a single screw.
A short incision is made extending distally from the coracoid in line with the delto-pectoral groove for 5cm:
The delto-pectoral groove is identified and seperated to expose the coracoid and conjoined tendon:
1cm of the tip of the coracoid is detached with the conjoined tendon
The subscapularis is split in the line of it's fibres
The coracoid is pre-drilled
The subscapularis is split to expose the joint capsule and glenoid neck
The glenohumeral joint is opened
The coracoid is fixed with a single screw to the anterior glenoid neck
