Q

What happens in the third stage of a tendinopathy (cellular level)?

A

increased proteoglycans
leads to increased water content -> causes increased cross section of tendon, breaks down cross fibres between collagen making tendon weaker
chemical alterations -> increased substance P, glutamate and lactate

Q

What happens in the final stage of a tendinopathy (cellular level)?

A

the common origin of the flexors and pronators

44
Q

What are the clinical signs and symptoms of medial epicondylalgia?

A

pain on the medial aspect of the elbow - pain on palpation
aggravated by resisted/repetitive wrist flexion on pronation, valgus stress, stretching

can involve ulnar nerve

45
Q

How can we manage golfers elbow?

A

education
load management]exercise
brace/taping
NSAID
corticosteroid injection
shockwave
surgery

46
Q

In what type of people is De Quervains most common in?

A

women
new mothers
40-50 years

47
Q

What causes De Quervains?

A

inflammation of the synovial sheaths of EPB, APL
swelling of the sheaths, leading to eventual thickening of the sheath
adhesions may develop between the tendon and the sheath which restricts normal tendon movement
enclosed tendons can become constricted
may occur spontaneously or can be initiated by overuse of the thumb

48
Q

What are the clinical signs and symptoms of De Quervains?

A

pain on the radial side of the wrist that can be referred to the thumb
aggravated by resisted thumb extension/abduction, or by stretching the affected tendon
pain on palpation of affected tendons

49
Q

How can we manage De Quervains?

A

Education
Load management
Exercise
Splinting
NSAID
corticosteroid injection
shockwave
surgery

50
Q
