Calcific Tendinitis Lowe Flashcards
What is calcified tendonitis:
-tendon condition produced by the deposit of calcium hydroxyapatite crystals
-occurs most often in the supraspinatus tendon
Characteristics:
- deposits do not appear to be caused by trauma or systemic disease (seldom related to rotator cuff tears); calcium deposits disappear and reabsorb as readily as they appear; found in healthy tissue and in people younger than expected with degenerative calcification; between 30-60 years; affect women more; identified with x-ray
-deposits usually located 1-2 cm proximal to supraspinatus insertion; can be mistaken for supraspinatus tendinitis/tendinosis
-four phases:
- formative: deposit develops and enlarges
- resting: deposit may or may not produce pain, can produce mechanical dysfunction
- resorptive: inflammation that works to break deposit down
- postcalcific phase: deposit fully reabsorbed, tendon heals
-pain varies from no to severe; found in asymptomatic patients and those with shoulder pain not related to calcification; when there is pain, resembles shoulder impingement syndrome; if pain comes on rapidly, it can help distinguish it from impingement pain, rotator cuff disorders and frozen shoulder; night pain common; rest may or may not provide relief; may increase when arm is raised above shoulder; may be unable to find pain-free position even when motionless
History:
sharp, sudden pain in shoulder; similar to toothache, deep, throbbing; limited shoulder motion; pain during activity and rest; ask about positions that produce or relieve pain; failure to identify consistent positions that decrease pain is indicative
Observation:
no specific findings; apprehension and movement guarding common due to pain avoidance; abduction/flexion motion are irregular due to pain or altered biomechanics; reflex muscular inhibition can cause weakness, uncoordinated movements
Palpation:
severe pain at the greater tuberosity of the humerus likely; residual tenderness and hypertonicity in surrounding muscles; swelling rarely evident
Range of Motion and Resistance Testing
AROM: pain with compression of irritated tissues possible with abduction/flexion; painful arc during abduction possible; erratic motion due to pain possible; lack of pain does not indicate absence of condition
PROM: as with AROM
MRT: abduction may/may not produce pain as affected tendon is recruited; may be pain in other
resisted actions where affected tendon is not recruited
Differential Evaluation:
rotator cuff tears, tendinosis, shoulder impingement syndrome, frozen shoulder/adhesive capsulitis, labral damage, bicipital tendinosis, cervical disc pathology, thoracic outlet syndrome
Suggestions for Treatment:
clear protocol has not been established; conservative measures including stretching, rest, shoulder slings, anti-inflammatory medications; relieve stress on supraspinatus tendon; extracorporeal shock wave therapy to break up calcification; massage could be contraindicated with damage fibres; may be possible in final resorptive phase to break up calcification
