BRISTOW OPERATION
PROCEDURE
Basuki W
Introduction
• The shoulder, by virtue of its anatomy &
biomechanics:
– most unstable & frequently dislocation
– 50% of all dislocations
– 95% anterior dislocation
• Failure to immobilize for 3-4 weeks after
reduction of initial treatment  recurrence
Anatomy Glenohumeral Joint
Anatomy Glenohumeral Joint
Pathologic Anatomy
• Bankart 1938:
– 2 types of acute
dislocation:
1. Humeral head is forced
through the capsule, antero-
inferior is the weakest
2. Humeral head is forced
through to anteriorly out of
the glenoid cavity, tears not
only fibrocartilegenous
labrum, but also tears
capsule and periosteum →
Bankart lesion
• Hill-Sachs lesion
– Shoulder is dislocated
anteriorly
– Humeral head is
impacted the rim of
glenoid
– Defect on postero
lateral humeral head
Surgical treatment
• Anterior instability:
– No single best procedure
• Ideally, the procedure:
1. Low recurrence rate
2. Low complication rate
3. Low re-operation rate
4. No harm (arthritis)
5. Maintain motion
6. Applicable in most cases
7. Allows observation of the joint
8. Corrects the pathologic
9. Not to difficult
Bristow operation
• The transferred short head of the
biceps & coracobrachialis muscles
are placed to the anterior glenoid
rim ( Havellius: “must be near not
over anterior glenoid rim)
– Good result :
• Coracoid process < 5 mm medial
to glenoid rim and inferior to
transverse line glenoid
• bony union
• Disadvantages:
– Internal rotation contracture
– Pathologic condition is not
corrected
– Injury to n musculocutaneus
– External rotation is limited
Good result :
• Coracoid process < 5 mm medial to glenoid rim and inferior to transverse line
glenoid
• Bony union
Technique Operation
• Deltopectoral incision
• Retract deltoid laterally,
pectoralis major medially
• Expose coracoid process
with its conjoined muscle
attachments
• Cut coracoid process 1-3
cm
• Mobilized coracoid tip
with muscle
• Protect the
musculocutaneus nerve
e
• Identify subscapularis
muscle and split in
line with its fibers
from lateral to medial
• Spilt anterior capsule
similar to the
subscapularis muscle
• Fix coracoid tip with
screw
• Inspect
musculocutaneus
nerve
• Close longitudinal
split subscapularis
• Reapproximate the
deltopectoral
fascia,subcutaneus
tissue and skin
Post Operative
• Immobilized in sling,
• After 2-3 days sling removed, and start
pendulum type exercises
• After 3 weeks start to isometric exercise
• After 6 weeks increasing ROM without
weights
• Noncontact sport are permited after 3
months
• Contact sport after 6 months
Case
Female, 30 yo, recurrent anterior
dislocation right shoulder
