Sports LE Flashcards
What is the staged return to play after concussion
Start after asymptomatic
5 stages - 24hrs each (therefore earliest RTP is 5days)
What is post concussion syndrome
Sx>3mo
What is the lucid interval
Temporary improvement of concussion sx
Beware epidural hematoma!
How to immobilize/transfer C spine injury
8 person lift > log roll
Helmet on, facemask off - taking helmet off can cause C spine hyper-lordosis
What are some C spine conditions that are CI to return to sports
Occipital cervical fusion
AA or C spine instab
Fusion >2 levels
Spear tackler’s spine
What is Spear Tackler’s spine
Congenital vs acquired C spine stenosis
Presents as less lordosis
Canal diameter <13mm (nml 17)
What is the workup for stingers
Nothing if 1 episode
Recurrent episodes: XR, voluntary F-E views
Bilateral - get MRI
Treat auricular hematoma
Aspirate
Tape
RTP for bloody nose
Must stop before RTP
Check for CSF leak - ring sign - CSF makes a ring in the blood on a surface
Septal hematoma
1. What is it
2. Treat
3. Complications
Subperiosteal hematoma
Treat = aspirate
Comp:
1. AVN septal cartilage - saddle nose deformity, collapse
2. Septal abscess
What to do for avulsed tooth
“Medical emergency”
Replace the root
Rinse saline, then in milk (buffer) solution
Hold by the top of the tooth (not the root)
Ideal replace within 1hr
What is the anatomy change for HOCM
Ventricle septum thickening
Will get a systolic murmur
What is the rhythm that develops for commotio cordis
V fib
Treat asthma
Beta 2 agonist (albuterol)
Where put a need for decompression tension PTX (adults vs peds)
Mid-axial line, 2nd vs 5th IC space
Peds: second intercostal space, midclavicular line
What is exercised induced laryngeal obstruction? Dx + trt
Exertional stridor
NO response to beta agonists (not exercise induced asthma)
Dx: laryngoscope during exercise
Trt: speech therapy (relaxation training)
Workup of exercise induced hematuria
Stop exercise
Repeat UA 48-72hrs
Further w/u
- Persists >7d after stopping exercise
- >50yo
Workup for suspected blunt kidney injury (think lower rib frx)
Sx: flank pain, hematuria
CT A/P
Remember single kidney si not a CI for RTP
Where do spleen injuries refer to
L shoulder
Difference in presentation testicular rupture vs torsion
Rupture: pain, hard voiding, doesn’t transilluminate
Torsion: rotated, high riding, lose cremasteric reflex
- Detorsion (manual vs OR) within 12hrs
Trt + RTP for herpes
Trt: -cyclovir
OK for RTP after 5 days
CI to RTP:
- Lesions within 48hrs
Bug + RTP impetigo
Beta hemolytic staph/strep
RTP
- All crusting gone
- Anti-virals for 72hrs
- No new lesions 48hrs
What is a gene specific to CA MRSA (vs HA)
PVL SCC Mec gene type 4
Trt + RTP CA-MRSA
TMP-SMX, clinda, doxy, linazolid
Often will require IV abx
RTP:
- 72hrs meds
- No new lesions 48hrs
Bug, dx, treat ringworm
Tinea corporis
Dx: fluoresces, KOH prep
Trt: topical antifunal
RTP: 72hrs meds
What is the female athlete triad
Period issues >3mo
Energy deficiency (doesn’t require formal eating disorder dx)
Osteopenia (>2 stress frx)
What temp / sx differentiate heat exhaustion vs stroke
104F (40C)
Stroke:
- CNS dysfunction
- No sweating
What is temp for hypothermia
<35C
Mechanism / complications of steroids
Increases mRNA -> increase muscle mass
SE:
- Testicular atrophy
- Alopecia
- Decrease HDL
What is:
Isotonic
Isokinetic
Isometric
Tonic - constant force
Kinetic - constant speed
Metric - constant length
What are the 3 skeletal muscle fibers? What cell heals skeletal muscle
1 = slow ox (endurance training)
2a = fast ox
2b = glycolytic (anaerobic - produces lactic acid)
Satellite cells
What is the difference between sickle cell trait and disease
Trait: heterozygous
- Exertional risk of rhabdo or arrhythmia
Disease: homozygous
- Sickle crisis
Risks with ant, postlat, and ant lat hip scope portals
Ant: LFCN>femoral
Ant-lat: SGN
Post-lat: sciatic, esp if hip ER
Cam lesions hallmarks
Alpha angle >55
Femoral RV
See a CARTILAGE inj - delam/flaps
Pincer lesions hallmarks
Tab RV = crossover sign
Increased CEA
Labral injury +/- ossification of the labrum (ant-sup most common)
Contre coup lesion - postinf tab
What is the CEA on an XR
What is normal vs dysplasia
Why do you care
CEA = AP XR, vertical line center hip, line off edge of the lateral tab
Nml 25-40
Dysplasia < 20 (aka shallow socket)
Don’t scope dysplasia!
What is the alpha angle (nml and CAM morphology)
Lateral XR
Line middle neck
Line where head exists perfect circle
Nml <50
>55 = CAM
Comp FAI surgery
HO
Frx if you take down >30% femoral neck diameter
