Q

Osgood-schlatter disease - causes

A

repetitive tension to the patellar tendon over the tibial tuberosity in young athletes

this can result in a small avulsion of the tuberosity and swelling

Q

OA - blood test

A

blood test are not helpful in diagnosing OA

20
Q

OA - radiographs

A

show the diminished joint space

21
Q

OA - goal of treatment

A

decrease pain and improve functio, and protect the joint

22
Q

what is viscosupplementation

A

a treatment that involves injecting hyaluronic acid into a joint to reduce pain and improve joint function

sometime used to treat oA

23
Q

should we use TENs or other forms of electric stimulation of rOA

A

nope

24
Q

should we used bracing for OA

A

nope

25
Q

what is primary OA vs secondary OA

A

primary - related to aging progress, old

secondary - degenerative disease of the synovial joints that result form some predisposing condition (trauma) that has adversly altered the art cart, young

26
Q

warmth of the joint and effusion and OA

A

warmth over the joints is not normally present but effusion

27
Q

what is the shoulder capsular pattern

A

ER> abd/flex > IR

28
Q

what is the hip capsular pattern

A

IR> abd > flex

29
Q

heberden’s nodes and bouchard’s nodes more in women or men

A

women

30
Q

psoriatic arthy - what is it

A

Rhematic condition

inflammation arthy that is often seen with psoriatic lesions

31
Q

psoriatic arthy - presentation

A

skin lesions -silver grey scaly spots on the scalp, elbs, knee and the spine

pitting of the finger nails and toe nails

pain and swelling in one or more joint

32
Q

psoriatic arthy - what population

A

20-50 in men and women

33
Q

Osteochondritis Dissecans - what is it

A

condition where subchondral bone and its associated cart crack and separate from the associated bone

34
Q

Osteochondritis Dissecans - cause

A

unkown

thought to be secondary to loss of blood flow to the affected area possible 2/2 rep microtrauma - causes the bone to die and seperate

35
Q

Osteochondritis Dissecans - primaryly effects what areas

A

knee

elb and ankle

36
Q

Osteochondritis Dissecans - symptoms

A

depends where the separation is

with functional activities:
- locking or popping

  • weakness
  • swelling
  • decreased ROM
37
Q

Osteochondritis Dissecans - imaging

A

xray, CT, MRI - can be used to confirm

38
Q

Osteochondritis Dissecans - special test

A

wilson’s test

39
Q

Osteomyelitis - what is it

A

an infection that occurs within the bone

40
Q

Osteomyelitis - what is it normally secondary to

A

staphylococcus within the bone

41
Q

what is staphylococcus

A

The bacteria that cause staph infections live harmlessly on many people’s skin, often in the nose and armpits and on the buttocks. They usually only cause an infection if they get into the skin – for example, through a bite or cut.

42
Q

Osteomyelitis - what events can lead to this

A

any event where the bone is damaged exposing it to microbes

  • surgical
  • compound fractures
  • puncture wounds
43
Q

Osteomyelitis - signs and syms

A

like other infections

  • systematic: fever and chills
  • localized: pain, edema, and erythema
  • secondary to a wound: change in the wound characteristics
44
Q

Osteomyelitis - imaging

A

bone biopsy - most conculsive

xray, MRI, US, PET > may provide extra infromation

45
Q

what is a PET scan

A

positron emission tomography (PET) scan

shows how well organs and tissues are working

used to diagnose and monitor conditions like cancer, heart disease, and brain disorders

46
Q

Osteomyelitis - lab signs

A

increase in WBC
