Elbow Stiffness: Biological and Neurological Considerations

Please note: exam questions are subject to change.

1. Elbows are built to flex and have an anteversion angle of: 90 degrees 60 degrees 45 degrees 30 degrees
2. The carrying angle formed by the long axis of the humerus and the long axis of the ulna is what in females? 5-8 degrees 9-12 degrees 13-16 degrees 11-14 degrees
3. When looking at osteokinematic vs. functional range of motion of the elbow, the "functional" range for the elbow for flexion and extension is... 30-130 degrees 0-80 degrees 0-145 degrees 0-50 degrees
4. The medial ligaments are the main source of stability to the valgus forces. Which fibers are taut in full extension? Middle fibers of anterior bundle Posterior fibers of anterior bundle All fibers of the posterior bundle Anterior fibers of the anterior bundle
5. The following is NOT a lateral ligament: Radial collateral ligament Medial ligament Accessory collateral ligament Annular ligament
6. In forearm rotation... The interosseous membrane binds the forearm bones and maintains alignment. The radius and ulna are not parallel in a supine position. The ulna rotates on the radius. There is no integration at the radio-ulnar joints.
7. An intrinsic contracture may have: A bone spur Exostosis Soft tissue contracture Joint derangement
8. Heterotopic bone formation is: An example of an intrinsic contracture An example of an extrinsic contracture Usually caused by low vascularity Not usually seen in the elbow
9. Which of the following is a TRUE statement about the elbow? There is a predisposition to pericapsular stiffness. The anterior capsule has a low concentration of fibroblasts. There is a slow conversion of fibroblasts to myofibroblasts in this area. There is no confluence to other soft tissue structures.
10. In the videos of the man in the striped blue shirt, the following clinical observations can be made EXCEPT: He swings his affected arm less during gait. He swings his affected arm more during gait. His left arm is his affected arm. There is more elbow extension in his right arm vs. his left.
