Q

Tendon sheath surrounds

A

-Tendons that run across a bony prominence- filled with synovial fluid (bursa)
-Sheet like (aponeuroses)

7
Q

Blood supply to tendon sheath

A

-Blood supply compromised when tendon is exposed to compression, friction, torsion-> avascular
-Limited blood supply from mm to bone

Q

What happens when placing load on tendon sheath

A

It will straighten out, collagen fibers will deform->accounts for 4% of tendon lengthening

Q

What happens if a tendon sheath lengths past 8%

A

Collagen links begin to fail-> causing microtearing, partial tearing, even complete rupture

Q

Grade 2 tendinitis

A

Px beginning + after activity

17
Q

Grade 3 tendinitis

A

Pain throughout activity + after, pain may restrict activity

18
Q

Grade 4 tendinitis

A

With daily activity + tends to get worse

19
Q

What is paratendinitis

A

Inflammation of Paratendon or tendon sheath

20
Q

What is tendenosis

A

-Degenerative changes occurring with chronic overuse tendon injuries (tennis elbow) No inflammation in tendon itself

21
Q

Contributing factors of tendenosis

A

Aging/avascularity may be contributing factors

22
Q

Medical treatment for tendinitis acute stage

A

-Rest
-Ice
-NSAIDS
-Stretching
-Strengthening
-Return gradually to activity
-In arms use support strap
-Surgery- necessary with total rupture especially in shoulder

23
Q

Other tendon pathologies

A

-Shoulder tendons
-Rotator cuff pathologies

24
Q

Impingement syndrom

A

-Inflammation, pain, edema within coracoacromial arch ( between acromioclavicular + glenohumeral joints)
-Pain in tendon when humerus is abducted against acromion
-Downward curving or hooked

25
Q

Rotator cuff tears due to

A

-Overuse
-Impingement syndrome
-Aging

26
Q

What muscle is usually affected in Rotator cuff tears

A

Usually supraspinatus affected

27
Q

What is Calcific tendinitis

A

Late- occurring stage of Rotator cuff tendinitis

28
Q

Cause of calcific tendonitis

A

Extreme pressure on Rotator in internal rotation at 90% abduction

29
Q

What happens to collagen in calcific tendonitis

A

-As collagen disintegrates, calcific deposits accumulate in cells
-Deposits are eventually re-absorbed causing pain and swelling

30
Q

Cause of trigger finger

A

-Overuse of flexor tendon of any finger, may develope nodular swelling, unable to move through tendon sheath + gets caught, finger stuck in flexion

31
Q

Symptom picture tendinitis acute stage

A

-Gradual onset, tenderness local to tendon one/two days after activity- increase to pain during activity
-Inflammation, heat along tendon/sheath
-Crepitus can develop
-Decrease ROM

32
Q

Symptom picture tendinitis chronic stage

A

-Pain during + after activity
-Chronic- inflammation, fibrosis, adhesions
-Crepitus may be present
-Decrease ROM + strength
-Flare ups->acute
-Rupture can occure with tendon degeneration

33
Q

Common tendinitis locations

A

Supraspinatus tendon
Infraspinatus tendon
Subscapularis tendon
Biceps long head tendon
Common flexor tendon
Abductor pollicis longus tendon
Extensor pollicis brevis tendon
Patellar tendon
Popliteus tendon
Tibialis posterior tendon
Achilles tendon

34
Q

Contraindications

A

No friction with Anti-Inflammatory
