Q

What can cause Osgood-Schlatter Disease?

A

Repeated stress from a lot of jumping, running, and bending (soccer, basketball, volleyball, ballet)

Stress pulls on the tendon that connects the kneecap to the shinbone. Eventually it will pull away

Q

What spinal roots supply the Tibial N?

25
Adductor magnus M. Action
``` Hamstring = Adduction, extend thigh Adductor = Adduction, flex thigh ```
26
What are the clinical presentations of Osgood-Schlatter Disease?
Pain and swelling Body can develop new bony growth to makeup for the gap, which leads to a bony lump in that spot.
27
What is Hilton's Law?

33
When would the ankle reflex be virtually absent?
If the nerve roots (S1, S2) are cut or compressed.
34
What is the absence/ decrease of patellar reflex known as?
Westphal's sign
35
Adductor magnus M. Origins
