A 22-year-old female patient arrives in the emergency department after a skiing accident. She was going downhill quickly when she twisted, fell, and reports hearing and feeling a "pop" in the right knee. The ED physician has diagnosed her with an ACL year and refers her to the orthopedic surgeon for arthroscopic repair. How is it positioned in relation to the other knee ligaments?
Ismail is an unrestrained passenger in the front seat of a car that strikes a
utility pole. Ismails tibia contacts the dashboard with great force. Which
ligament of the articulatio genus would most likely be torn during this
injury? *
O anterior cruciate
O patellar ligament
O fibular (lateral) collateral
O posterior cruciate
tibial (medial) collateral
If you have a major injury to an appendage you may want to stop the bleeding by tying a tourniquet. Tourniquets are belt-like apparatuses that need to be applied at least 2 inches above the injury, but not on a joint. Knowing this information indicate over which blood vessel(s) you would apply the tourniquet if someone received a deep cut:
To the vessels around the carpals?

- The movement during which the knees or elbows are bent to decrease the angle of the joints is known as _______________.arrow_forwardMalcolm injured himself after trying to break his fall with outstretched arms. The emergency room physician took one look at his shoulder and saw that Malcolm had a broken clavicle (and no other injury). Describe the position of Malcolm’s shoulder. What part of the clavicle was most likely broken? Malcolm was worried about injury to the main blood vessels to his arm (the subclavian vessels), but he was told such injury was unlikely. Why could the doctor predict this?arrow_forwardA 22-year-old female patient arrives in the emergency department after a skiing accident. She was going downhill quickly when she twisted, fell, and reports hearing and feeling a "pop" in the right knee.

- When the shoulder joint dislocates, it most commonly dislocates posteriorly, meaning that the joint capsule tears on the posterior side and the head of the humerus pushes partly out through the capsule. Why do you think the posterior capsule more commonly tears? (HINT: Consider the structure of the capsule and look at the ligaments of the shoulder joint.)arrow_forwardName three static stabilizers for the shoulder and explain the overall function of this group of tissues. Dynamic stabilizers consist of muscles that surround the joint and contract to produce movement. One group of these muscles is called the rotator cuff. They compress the head of the humerus into the glenoid fossa and stabilize movements in all directions. Name the four muscles of the rotator cuff. 1. 2. 3. 4.arrow_forwardIf your foot is planted and immoveable (think lug-soled boot on a muddy trail), and you are hit from behind (think mountain biker out of control), which knee ligament is more likely to be torn...the anterior cruciate ligament or the posterior cruciate ligament? Explain your answer in detail, and in particular, how the impact affects the relative movements of femur and tibia and why the ligament you chose is stretched to the breaking point by this motion. Think and explain carefully...this stuff is confusing.arrow_forward

Your physician remarks, "Well, it's better than breaking your tibia". explain why a fracture of the tibia would be worst than a fracture of the fibula.arrow_forwardThe glenoid labrum can become torn from overuse or direct injury to the shoulder joint. Considering the function of the glenoid labrum, describe some of the consequences of a large tear in the glenoid labrum.arrow_forward
