Shoulder (Exam 4) Flashcards
____ joint has a lot of mobility and is unstable.
Glenohumeral
Repetitive overhead lifting. Stress and friction result from crowding and compression of RTC tendons under the subacromial arch.
Subacromical Rotator Cuff (RTC) Impingement
Compression primarily of supraspinatus tendon as pass under coracoacromial ligament between acromion and coracoid process.
Primary Impingement
GH instability creates reduced subacromial space because humeral head elevates.
Secondary Impingement
Degenerative changes decrease subacromial space. Bony osteophyte formation occupy space under anteroinferior surface of the acromion decreases space.
Other causes of Subacromial Rotator Cuff (RTC) Impingement
___ most commonly affected tendon in impingement. Just proximal to insertion on greater tuberosity is hypo vascular with repeated overhead arm motions, which compromise blood supply. “Critical Zone”.
Supraspinatus
Decrease overhead activity. Control pain and swelling (ice massage). Stretching (Posterior Shoulder Capsule). Strengthening (External Rotators, Scapular Stabilizers). Strengthen, Stabilize Scapulothoracic Musculature First. Address RTC Weakness Next (External Rotators).
Rehab of Primary and Secondary RTC Impingement
Performed in conjunction with RTC repair. Increases space and subacromial space.
Subacromial Depression for Impingement
Small RTC Tear
Less than 1 cm.
Medium RTC Tear
Less than 3 cm.
Large RTC Tear
Greater than 5 cm.
Active motion and pain-free exercise can begin as soon as patient tolerates.
Small Cuff Tears Rehab
Tissue protection must be longer to allow for healing. Splint 4-6 weeks.
Medium and Large Tears Rehab
If _____ allowed too early, healing compromised due to stress on repaired tissue.
Full ROM
Anterior Deltoid Fibers Resected
Open Procedure
Lateral Deltoid Fibers Splitting and Arthroscopic Decompression
Mini-Open Procedure
Longer To Heal
Larger Cuff Tears
Early or Acute Phase. 6 weeks. Codman’s (Pendulum) Exercises within first weeks to restore mobility and stimulate mechanoreceptors. With small tears - submax isometrics as tolerated. PROM - pulleys.
RTC Repair Rehab Phase 1
Intermediate Phase. 7-12 weeks. Progressive ROM with caution of repetitive shoulder abduction and forward flex above 90 degrees. Scapular stabilization exercises. Resistive theraband for progressive strengthening of RTC below 90 degrees.
RTC Repair Rehab Phase II
Minimum Protection Phase. Begins when increased motion without signs and improved strength. 13-21 weeks. Gradual return to normal activities.
RTC Repair Rehab Phase III
No AROM or active strengthening for 3-4 months. Immobilization is key. PROM with restrictions. Codman’s pendulum exercises and gentle AAROM may begin 3 months post op. Submax isometrics and scapular stabilization may be added cautiously 2-4 months after surgery. Full function and recovery may take 10 months.
Massive RTC Tears
____ most commonly dislocated joint. Men greater than women. Anterior greater than posterior. Result of indirect trauma.
Shoulder
With shoulder in Abd, Ext, ER.
Anterior
With shoulder in Abd, Flex, IR.
Posterior
Dislocations can be accompanied by.
RTC Tear, Glenoid Labrum Tear (Bankart Lesion), Compression or Impaction Fx (Hill-Sachs Lesion)
Avulsion of the capsule and glenoid labrum off anterior rim of glenoid resulting from traumatic anterior dislocation.
Glenoid Labrum Tear (Bankart Lesion)
Injury to posterolateral humeral head due to anterior shoulder instability. Does not cause the instability.
Compression or Impaction Fx (Hill-Sachs Lesion)
Immobilization avoid positions that may reproduce dislocation.
Non-Operative Managment
For anterior dislocation avoid.
Abduction, External Rotation
Reattach and tighten capsule using staple, suture, or thermal repair.
Anterior Shoulder Capsulorrhaphy
Move subscapularis from lesser to greater tuberosity.
Magnuson-Stack Procedure
Surgical repositioning of coracoid process, coracobrachialis, and short head biceps to GH neck.
Bristow Procedure
Slack in capsule is reduced. For patients with anterior instability.
Capsular Shift
Pain, decreased ROM, capsular inflammation, fibrous synovial adhesions. Females more than males. Typical 40-60 years old. Many are diabetic.
Adhesive Capsulitis “Frozen Shoulder”
Idiopathic and spontaneous. Most common.
Primary Adhesive Capsulitis
Post trauma or immobilization. In older patients, 1-2 days may be enough immobilization to cause adhesive capsulitis.
Secondary Adhesive Capsulitis
Slow onset of pain and decreased ROM. 6 weeks to 9 months.
Stage 1 Freezing Stage
Slow improvement in pain, but the stiffness remains. 4 months to 9 months.
Stage 2 Frozen Stage
