Q

what is chronic exertional compartment syndrome?

A

extremely painful when pressure within LE compartment increases
pain will increase during exercise, and stops soon after ceasing
diagnosis requires referral to physician. the pressure within the LE compartments are measured before and after exercise

A

localized pain in posterior distal leg or heel
pain and stiffness following periods of inactivity
intermittent pain experienced during activity and exercise, may improve with mild activity
pain with stair climbing, calf stiffness especially in AM

26

decreased ability to perform repetitive unilateral heel raises compared to the contralateral side; may have decreased DF ROM
increased running frequency or distance, change in shoewear

27
Q

what is non-insertional achilles tendinopathy?

A

location is 2-6 cm proximal to insertion, zone of decreased vascularity
bulbous area may be noted in mid-substance of tendon with or without pain

28
Q

what are some types of non insertional achilles tendionpathy?

A

paratendonitis
tendonosis
paratendonitits with tendonosis

29
Q

what is paratendonitis?

A

inflammation of the lining around the tendon

30
Q

what is tendonosis?

A

noninflammatory, age related degeneration of the tendon itself

31
Q

what is paratendonitis with tendonosis?

A

paratendon inflammation with intratendinous degeneration

32
Q

what is insertional achilles tendinopathy?

A

location- at achilles distal insertion on calcaneous
tenderness, swelling over insertion at calcaneous

33
Q

what types of insertional achilles tendinopathy are there?

A

haglund’s deformity and subcutaneous calcaneal bursitis (“pump bump”)

34
Q

what is Haglund’s deformity?

A

deformity of the posterior calcaneus putting retrocalcaneal bursa and achilles tendon at risk for increased compression

35
Q

what is the operative treatment for insertional achilles tendinopathy?

A

haglund deformity, retrocalcaneal bursa is aggressively resected
