Card Set Information
What is a bankart lesion? When does it commonly occur? What is a bankart fracture?
-Detachment of the anterior glenoid labrum
-85% incidence in anterior dislocations
-Break off piece of glenoid
What is a Hill-Sachs lesion?
When does it commonly occur?
-Compression fracture or depression defect to the postero-superior aspect of the humeral head
-Often occurs with anterior dislocation and accompanied Bankart lesion
Signs/symptoms of anterior dislocation
-Loss of rounded shoulder contour
-Arm held locked in abd, slight ER
-All mvmts limited and painful
Jobe's four P's of Rehab
1) GH PROTECTORS
: infra, teres minor, subscap, supra
2) Scapular PIVOTERS
: traps, serratus, levator, rhomboids
3) Humeral POSITIONERS
4) Humeral PROPELLERS
: Lats and pecs
Arthroscopic Bankart Procedure
-reattachment of capsule and/or labrum to glenoid rim
-if no rotator cuff tightening then shoulder ROM should not be affected
-Inferior capsular pouch tightened with an anterior repair if there is anterior/inferior instability
-Good results in athletes
-Thermal capsular "shrinking"
-Use lasers to heat lax joint capsule and cause collagen to shrink in length which tightens capsule
-Not suitable for hypermobile pts
-Long term outcomes not as good
-Transfer of coracoid (with conjoined tendons of biceps and coracobrachialis)
-Antero-medial restraint of shoulder
Transfer subscapularis tendon lateral to bicipital groove
Half Moon Sign
What does its absence indicate?
: medial border overlaps with glenoid fossa
-absence indicates post dislocation
When might you see a reverse Hill-Sachs lesion?
-After a posterior shoulder dislocation
-(on anterior aspect of humerus)
