Locomotor: Sports Injuries Flashcards
Describe the main features of a walking gait
Think in terms of phases, support and significant moments
Main differences between a running gait and a walking gait?
- There is no duel support, instead this is replased by a float phase
- Greater upper body movement
- Faster velocity, shorter cycle time, greater stride
In children if they have been injured during activity and there was a popping sound what could this imply?
Apophyseal avulsion
What is apophyseal avulsion?
This is where a tendon of a child is overstrained. However usually the tendon is stronger than the apophysis hence it pulls of the boney structure (e.g. tuberosity) breaking the apophysis.
Usually occures acutely and accompanied by a “pop”
Treatment of apophyseal avulsion
Conservative:
Rest, protective weight bearing and stretching
Surgery rarely needed unless the displacement is extreme
What is apophysitis and what is the treatment?
A chronic injury injury of the apophysis due to overuse and stress
Treatment is conservative with activity modification, NSAIDs, rest and stretches
Three types of shoulder dislocation and the reasons they might occur
- Anterior to glenoid fossa, most common and occurs from sporting injuries
- Posterior is more uncommon and occurs from extreme muscle contraction during seizure or electrocution
- Inferior occurs from hyperabduction and only from high energy trauma making it extremely rare
Anterior shoulder dislocation presentation
Squared off shoulder and upper limb held in adduction and internal rotation
What is harder to spot in a radiograph:
Anterior or posterior dislocation
Posterior is harder to spot, it is often missed and a second view can be helpful
3 Injuries that can occur in an anterior shoulder dislocation?
- Hills-Sachs lesion
- Bankart lesion
- Surrounding soft tissue injury
Hills Sachs - ping pong ball injury - golf ball - played on hills found in sachs
Bankart lesion - break of plate - break the bank steal the art
What is a Hills-Sachs lesion?
This is where the posterior humeral head gets a compression fracture form the glenoid rim
Think a ping pong ball being pushed. Remeber by ping pong ball = golf ball = played on hill and carried in sacks
What is a Bankart lesion?
This compliments the Hills-Sachs and is where the anterior rim of the glenoid fossa is ripped by the humeral head
Treatment of an accute shoulder injury?
The 3 Rs
- Reduce
- Restrict
- Rehabilitate
- Where is the meniscus
- What is it made of
- What does it look like
- What are it’s functions?
- They sit above the condyles of the tibia
- Consists of tough fibrocartilage
- Looks like two Cs facing eachother - Coco Chenel Logo
- Functions are force transmissiona nd stability. Medial attaches to the MCL
What history and physical indications might suggest a meniscal tear?
- Twisting injury
- Slow onset of swelling (Immediate may indicate ACL/PCL)
- Locking (if the knee can’t fully extend this could indicate a displaced meniscal tear preventing the joint from extending)
- Clicking
