Sports Medicine Flashcards
True or False: Conditioning programs are encouraged
True
How often should conditioning programs include aerobic training?
3-4 days/week
What is the difference between weight training and power lifting?
- Weight training: Many reps with low resistance
2. Power lifting: Fewer reps with increased resistance
Which is safe for preadolescents… weight training or power lifting?
Weight training
Why is power lifting not safe for preadolescents?
Risk of apophyseal avulsion fractures
What are the 2 forms of heat illness?
- Heat exhaustion
2. Heat stroke
Is heat exhaustion or heat stroke more mild?
Heat exhaustion is more mild
Mild dehydration, core temperature <104F, headache, thirsty, nauseated, vomiting
Heat exhaustion
What is a way to distinguish between heat exhaustion versus heat stroke?
Sweating- Heat exhaustion sweats, heat stroke doesn’t
What is management for heat exhaustion?
Stop exercising
Drink fludis
Name 4 findings in heat stroke
- Temperature >105F
- Flushed, hot, dry skin (no perspiration)
- CNS depression (confusion, vertigo, syncope, lethargy
- Severe dehydration
How does heat stroke lead to end organ damage?
Release of endotoxins and cytokines
*Dehydration isn’t only cause of problems in heat stroke
True or False: Heat stroke is a medical emergency
True
What is management for heat stroke?
- Stop activity
- Get child out of heat
- Decrease core body temperature
- Rehydration via IVFs only +/- vasopressors if needed for BP
True or False: Simple evaporative cooling may be as effective as active cooling via application of ice
True
Why is oral rehydration inappropriate in heat stroke?
Due to CNS depression
Cooling a heat stroke patient below what temperature could lead to hypothermia and is inappropriate?
101-102F
What neurological findings point to heat stroke versus heat exhaustion?
Delirium, coma, seizure
Describe a grade 1 sprain
Minor stretching of the ligament
Minimal discomfort or loss of function
Initial injury often doesn’t come to medical attention
Describe a grade 2 sprain
Ligaments partially torn
Tenderness and swelling
Ecchymosis
Some loss of function
Describe a grade 3 sprain
Ligament completely torn
Significant pain, tenderness, swelling, loss of function
Usually seeks medical attention
What ligament is usually affected in an ankle injury?
Anterior talofibular ligament
*Inversion injuries involving lateral ligaments
What % of sports injuries involve lower extremities?
75%
What are the 2 most common sports injuries?
- Contusions
2. Ankle sprains
What % of ankle injuries are sprains of lateral ligaments?
85%
What are most injuries that occur in the knee and ankle due to?
Incomplete healing of a previous injury
What are 5 criteria for a child to return to sports after an ankle injury?
- Full ROM
- Full strength
- No swelling
- No pain
- No join instability
What should pain over a bone physis in a pre-adolescent child be assumed to be (even if XR is normal?)
Salter Harris I Fracture
What is the immediate treatment of an ankle sprain?
Apply ice
*Should continue for 20 minutes at a time over the first 36-48 hours
Child who recovers from an ankle injury, returns to competitive sport, then gets another more severe injury in the same ankle… most likely cause?
Re-injury: Child returned to competitive play too soon
Child whose ankle/lateral leg got stepped on during basketball. No deformity, but there is a bruise and marked swelling. Foot has strong dorsal pulse and some diminished sensation to pinprick and light touch… most appropriate next step?
Obtain compartment pressures- Bruising with marked swelling and decreased sensation point to compartment syndrome
*Presence of pulse and lack of paralysis just mean it’s in the early stages (doesn’t rule this out)
What are the 5 P’s of compartment syndrome?
- Pain
- Paresthesias
- Pallor
- Paralysis
- Pulselessness
4/5 are late findings (absence doesn’t rule it out)
When would ice and compression dressings be indicated for compartment syndrome?
Never- Ice won’t help and compression dressing will make it worse
What usually causes subluxation of the patella?
Indirect trauma
Pop after change in direction off a pivoted knee, pain over lateral aspect of patella, possible deformity over the medial aspect patella?
Subluxation of the patella
What can subluxation of the patella represent?
Patellofemoral instability
What is management of subluxation of the patella?
Developing and maintaining quadriceps and hamstring strength as well as flexibility
Anterior knee pain in adolescents involved in jumping, running, and squatting sports due to patellar maltracking?
Patellofemoral syndrome
Which gender does patellofemoral syndrome affect more frequently and why?
Females- Higher Q-angle between femur/tibia
How is patellofemoral syndrome diagnosed?
Clinically (XR isn’t helpful)
What is management of patellofemoral syndrome?
- Knee bracing
- Patellar taping
- NSAIDs
- Quad strengthening
When should you refer patellofemoral syndrome to orthopedics?
If condition doesn’t improve after 4-6 months of conservative intervention…
- Knee bracing
- Patellar taping
- NSAIDs
- Quad strengthening
Large area of swelling over thigh after blunt trauma?
Soft tissue hematoma (can be big due to blood supply to quadriceps)
*Also consider fracture or lytic lesion is clues are there
What does any athlete with a history of knee “giving way” with activities need to be evaluated for?
ACL tear
Which gender are ACL tears more common in?
Females (3-4x more common than males)
How does prepatellar bursitis present?
Anterior knee pain over patella, visible swelling
What is treatment for prepatellar bursitis?
NSAIDs, padding during sports with recurrent trauma (volleyball)
What is management for a soft tissue hematoma in the thigh?
NSAIDs, ice, rest
What complication should you be mindful of in a severe soft tissue hematoma of the thigh?
Drop in Hct- Fatigue/Dizziness
Pain over anatomical snuffbox (dorsum of hand near base of thumb)?
Scaphoid fracture
True or False: Negative XR is common in a scaphoid fracture
True
True or False: Scaphoid fractures have a poor prognosis
True
12 year old gymnast with left wrist pain, progressively worse over 3 months, no known injury. No swelling, normal ROM, no pain over wrist joint, point tenderness at distal radius. Most likely explanation/Management/XR Findings?
Distal radial epiphyseal injury
Rest and splint wrist until healed (if continues training, likely to disrupt growth plate)
Can do training that doesn’t involve wrist (doesn’t have to stop all training- for example, running)
Who and How to supracondylar humeral fractures typically occur in?
Boy age 5-8 after falling on an outstretched arm that is hyperextended at the elbow
What does a supracondylar fracture of the humerus impact?
Vasculature
*May be no external signs in presence of severe injury/trauma
If trauma to elbow is mentioned in question, what do you need to consider?
Neurovascular compromise
What are some signs of vascular damage associated with a supracondylar fracture?
Pallor/cyanosis of distal extremity
Pain on passive extension of fingers
True or False: A nondisplaced supracondylar fracture will be seen on XR
False- It might not be obvious
True or False: You should treat pain more versus less aggressively
True
Risk for respiratory depression with opiates is less than commonly believed (titrate up on dose to manage pain appropriately)
