ability to teach this course
What We Know--maybe
• We understand the basics
• Debate regarding function
• Debate regarding treatment
Anatomy
• Originates from posterior superior labrum
• Coracohumeral, SGHL• Tuberosities• Rich innervation
Function
• Long felt to be humeral head depressor
• Stability?• Dynamic role– EMG variable
Diagnosis
• PE is sensitive, not specific
• Variety of tests– Yergasons– Speeds– Subscap lift off
• MRI• Dx at surgery
What We Don’t• Why it hurts• What is best treatment
Treatment options
• Tenotomy– Easy to do– Popeye muscle– Cramping
• Tenodesis– Preserves length– Minimizes Popeye– Less cramping– Requires implant– Longer surgery
However
• Ospar (2002)– No significant difference
• Slenker (2012)– Increase in cosmetic
deformity, otherwise no significant difference
Tenotomy• Fifty percent rule• Fix associated pathology• Variety of devices• Don’t leave a stump• Pre-op planning

Tenodesis
• Soft/ semi soft– Involves suturing to
rotator cuff– Suture anchors– Conjoint tendon– Pectoralis major– May not be much
different that tenotomy
Tenotomy
• Keyhole technique
Socket with Screw
• Variety of systems• Essentially creating
socket and using interference screw, or push-lock type device
• Burkhart (2012) has quantified length relationship– 25 mm
Sub pectoral
• Small incision• Good for chronic tears• Length tension
relationship important• Burkhart (2012)– 15 mm from MT junction– Suture 2cm above lower
margin
Results
• Systemic review by Slenker et al. (2012)– No consensus– Few controlled trials– Cosmesis only signif. diff
• Most studies fail to show significant difference– Steadman
• Arthroscopy 1/2011
Discussion
• If tear is less than 50%, debridement
• Greater than 50%, over sixty, tenotomy
• Younger, high demand, tenodesis– Bony procedures have
higher rate of success
