Glenohumeral Internal Rotation Deficit / Posterior Capsular Contracture

Glenohumeral Internal Rotation Deficit (GIRD) occurs as a result of a loss in the degree of shoulder internal rotation movement. This is determined by a measurement of a loss of 20° compared to the opposite shoulder.

 

Symptoms

• Shoulder Stiffness

• The feeling that a prolonged warm-up is needed

• Loss of Velocity

• Posterior Shoulder Pain

• Pain in the late cocking phase of your throw

• Posterior Shoulder Tightness

 

Causes

• Repetitive overhead throwing

• Rotator Cuff Tightness

• Posterior Capsular Contracture

 

Diagnosis

• Physician Exam

• MRI

• MR Arthrography

 

Prevention

It has been shown that stretching after a pitching session will help prevent symptoms of GIRD.

 

Treatment

Non-surgical:

• Rest 

• Ice

• A prolonged course of Physical Therapy is usually recommended before any surgical intervention. This would include stretching and strengthening to improve shoulder mechanics.

 

Surgical:
