Q

Stable vs. Unstable Grade 2 high ankle sprains

A

Positive ER test, Positive squeeze test, and pain with palpation of ant tib/fib lig and deltoid lig - if all these is as reliable as an arthroscopy - but if dont have all four doesnt mean you dont have it

25
Treatments for ankle sprain
NSAIDs for pain relief and limit swelling Continue ice until sweling is gone or painfree WB If pain with weight longer than 7 days consider BK walking cast or CAM walker with ACE wrap
26
Treatment for ankle sprain - ROM
Start ankle ROM exercises when NBW (write alphabet) | When ROM exercises are pain free start strengthening and stretching
27
Ankle Sprain - Isometric strengthening exercises are used for
rehabing the peroneals which often are weak after an ankle injury and can lead to instability
28
Ankle sprain - stretching of the achilles tendon is necessary why
dec ankle joint DF places the narrow post talus further distally in wider ant ankle joint - most unstable position of the ankle People with ankle sprains may have tight achilles so youd want to stretch it and make it more flexible to prevent further injury
29
Isotonic strengthening - ankle sprain - used for
anterior msucle group | Isometric and then isotonic
30
Ankle sprain - important to do proprioception because
residual instability may be a result of damage to the afferent nerve fibers in the capsule
31
Proprioception exercises for people with ankle sprain
stand on injured foot, first with eyes open and then with eyes closed Continue until patient can balance on one foot for one minute with eyes closed
32
Ankle sprain - proprioception - you can also use a
BAPS board and have patient stand on one foot in center and rotate disk clockwise and then counterclockwise with eyes open and then with eyes closed
33
Ankle sprain - return to full activities when?
when able to stand on toes of ankle for 20 seconds and hop on toes 10 times and can cut and run a figure of eight
34
Ankle sprain - bracing
use bracing for at least 6 months | Nonbraced athletes have 3 times the risk of injury
35
Ankle sprain - orthotics
especially USB insert, to limit varus deformities
36
Ankle sprain - type of shoe
High topped laced athletic shoes
37
Ankle sprain and taping
He doesnt recommend it - provides 10% inc in max resistance to inversion moments but after 40 min of exercise is not protecting anymore
38
Ankle sprain - re eval
Consider re-eval with bone scan to rule out occult fracture if sx do not dec within 2 wks of initiating therapy
39
Ankle sprain predicting chronic ankle instability
You can predict it after first ankle sprain by having them complete jumping and landing tasks within first 2 weeks of first time LAS
40
Posterior Tibial Tendonitis
Most common cause of medial ankle pain, especially without identifiable trauma
41
Most common etiology of PTT dysfunction is
pronation
42
Other causes of PTT
obesity, inflammatory arthritis, oral or injectablle steroids
43
S/S of PTT
Pain usually with noticeable swelling, along medial aspect of ankle and rearfoot Noticeable flatfoot Too many toes sign - due to increased forefoot abduction
44
Treatment PTT
Base on stage of deformity | Usually all early or stage 1 deformities will respond to conservative care
45
Treatment PTT - conservative care
Flexible foot Mild weakness on single heel rise Absence of too many toes sign Stages 2 to 4 require surgery
46
Orthotic for PTT
UCBL device Best option might be a Richie brace though Can consider an AFO but usually too bulky and bothersome for patient PT is a must Steroid injection into tendon body is contraindicated
47
Achilles Tendinopathy - Most pathologies occur
3 to 6cm above the insertion of the achilles
48
Achilles Tendinopathy - area of
Poor vascular supply (watershed area)
49
Achilles tendinopathy can be
insertional or noninsertional
50
Achilels tendinopathy - insertional is often associated with
calcification of tendon substance
51
Etiology of achilles tendinopathy
Can be short gastroc-soleus Excessive uphill running (passive DF stretching tendon) Sport that involves more toe standing Pronation or pes cavus foot Too flat a shoe Inflammatory arthropahty with enthesopathy
52
Diagnostic imaging for achilles tendinopathy
MRI, ultrasound
53
Other ways to diagnose an achilles tendinopathy - rupture
Thompsons test - but know that false pos can occur | Very little pain with dramatic inc in passive DF
54
What can you see or feel with an achilles rupture
dell (feels like dead space) along the post aspect of the achilles where the rupture ocurrred
55
Tx for tendinopathy
``` RICE Min of 3/8 inch heel lift NO stretching until tendon pain eases (eccentric) Topical diclofenac Iontophoresis NSAIDs Orthotics Cast immob ```
56
Problematic fractures
5th metabase calcaneal joint depression Ankle syndesmotic rupture
57
5th Metabase fracture - when confined to tuberosity
NWB, BK cast immob for 6 weeks
58
5th metabase fracture - when somewhere btw 1.5 to 3cm from the tip of the tuberosity is called a
jones fracture and in an athlete surgery is accepted as tx of choice
59
Jones frcture has a reputation as
a poor healer | literature says that conservative tx or surgical care is successful at healing though
60
Calcaneal joint depression fracture - at impact what happens
the posterior facet of the calcaneus is driven plantarly into the body of the calcaneus by the lateral talus
61
Calcaneal joint fracture outcome
extrememly poor with or without surgery
62
Calcaneal joint fracture - ROM and WB
Early ROM and NWB Boot in neutral position Compression stocking
63
Types of ankle fractures
Unimalleolar Bimalleolar Trimalleolar Syndesmotic
64
With an ankle fracture dont forget to look for
fibular fracture AND medial malleolar fracture
65
Most common type of ankle fracture
Spiral oblique fracture of the fibula starting at level of ankle joint 75%
66
Most serious and longest healing ligament injury involves what and is what
Ant-Inf tibial-fibular ligament and involves damage to the syndesmosis
67
Ant Inf Tib Fib ligament injury with syndesmosis will have pain with
ER of the foot on passively PF ankle (Kleiger) May have pain with squeeze Only reliable detection of rupture is intra-operatively
