ankylosis of elbow
22
Q

What ROM is expected following TEA

A

15-130 degrees

23
Q

What are lifting restrictions post TEA?

A

very light

1kg repeated, 5kg max

24
Q

What are the most common locations of heterotropic ossificans following elbow injury?

A

1) b/w brachialis and anterior capsule

2) between triceps and posterior capsule

25
How common is heterotropic ossificans following significant elbow trauma?
Fairly common, up to 56% of fracture/dislocation. Peak incidence is 2 months following injury
26
What is the hallmark symptom of CRPS?
intraceable pain in nonperipheral nerve distribution. Evidence of edema with sensory and motor changes also present Allodynia and hyperalgesia also common
27
What may lead to chronic insufficiency of radial collateral ligament (3 items)
1) postural deformity-potentially following childhood fx 2) overuse of varus stress during weight bearing. (ex: crutch usage) 3) iatrogenic: lateral tendionpathy surgery
28
What is typical mechanism of acute UCL tear
FOOSH
29
Which phases of throwing most stress UCL?
cocking/late cocking-> acceleration
30
Which portion of UCL most susceptible to injury?
anterior
31
Which motion at elbow decreases UCL stress during throwing?
elbow flexion
32
Which has a higher success rate for return to sport following UCL surgery, reconstruction or repair
reconstruction
33
How far out of UCL surgery is throwing typically allowed?
4 months
34
What is little leaguer's elbow?
apophysitis/avulsion fracture of medial elbow
35
What shoulder motion is typically found to be limited in throwers with UCL injury?
GHJ IR.
36
When should eccentrics be introduced in patients with medial elbow tendinosis?
early in treatment, and should be sufficient load to elicit discomfort
37
What patients may be candidates for medial elbow tendinosis surgery
- failed PT - failed steroid injections - longer than 1 year symptoms - intra-articular symptoms
38
What benefits for coritcosteroid use are there with elbow tendinopathy?
short term benefits, but worse than PT medium and long term
39
What forms the cubital tunnel?
walls: medial condyle and olecranon roof: aponeurosis floor: UCL, joint capsule, olecranon
40
What is success rate does non-operative management have with low level cubital tunnel syndrome?
50%
41
What position is important to limit with cubital tunnel syndrome
excessive flexion- night splint at 30-45 degrees often utilized
42
What motions/activities should be limited with cubital tunnel syndrome
flexion beyond 90 degrees wrist and finger flexion valgus stress
43
With cubital tunnel syndrome, at what stage should aggressive STM be added to treatment?
later in rehab
44
What hand symptoms are indicative of anterior interosseous nerve syndrome?
inability to make "ok" with hand. Indicative of decreased FDP of index finger and FPL function
45
Which is more likely to have motor symptoms, posterior interosseous or radial tunnel syndrome?
posterior interosseus. Radial tunnel is pain dominant
46
If forearm band for lateral tendinopathy increases symptoms/weakness, what should be considered?
radial nerve involvement
47
What differentiates PIN syndrome and radial tunnel syndrome?
RTS lacks motor involvement
48
What populations are at risk for osteochondritis dissecans at elbow?
young female gymnasts and adolescent male baseball pitchers
49
Healing time frame for osteochondritis dissecans?
return to activities at 3 mo, full activity at 6 mo
50
What is likely to be primary sign of RA of elbow?
loss of extension
51
Is there loss of joint space in elbow OA?
not typically, more common is presence of osteophytes and joint capsule contracture
52
Elbow mwm cpg
Age under 49, strong on opposite grip, low pain free on involved side
