MSK Flashcards
If a patient has Adhesive Capsulitis, what joint mobilization should you do to improve their shoulder ROM?
Posterior-inferior glide
The coracohumeral ligament prevents a dislocation in which direction?
Inferior or caudal
The superior glenohumeral ligament limits which shoulder motion(s)?
Limits ER and inferior translation of the humerus
The middle glenohumeral ligament limits which shoulder motion(s)?
Limits ER and anterior translation of the humerus
The inferior glenohumeral ligament limits which shoulder motion(s)?
Anterior band: limits ER, anterior, and superior translation
Posterio band: limits IR and anterior translation
Purpose of the transverse humeral ligament.
Protect the long head of the biceps tendon in the groove.
Does the ulna supinate or pronate when the elbow goes into flexion?
Supinates
Does the ulna supinate or pronate when the elbow goes into extension?
Pronates
How is the distal radius shaped in regard to the carpal bones?
Biconcave
Convex scaphoid and lunate articulate with concave radius
How is the distal ulna shaped in regard to the triquetrum?
Convex relative to the triquetrum
First CMC is what kind of joint? Describe how it changes when moving in the medial/lateral direction vs the anterior/posterior direction.
Saddle joint
In the medial/lateral direction the trapezium is convex; in the anterior/posterior direction, the trapezium is concave.
What is the orientation of the glenoid fossa?
Anterior, superior, and lateral
What is the orientation of the femur in the acetabulum?
Anterior, superior and medial
What is normal angle of inclination?
115 to 125 degrees
Coxa valga angle is what value?
> 125
Coxa vara angle is what value?
< 115
Anteversion is considered excessive if it is what value?
> 25-30 degrees
Retroversion is considered excessive if it is what value?
< 10 degrees
If someone has excessive anteversion at the hip, what will they do to compensate and WHY?
They will perform in-toeing because if they don’t, they place the femur too far anterior, risking a sublux or dislocation. After a patient does in-toeing, the femoral head is placed more posteriorly.
If someone has excessive retroversion at the hip, what will they do to compensate and WHY?
They will perform out-toeing because if they don’t, they place the femur too far posterior, risking a sublux or dislocation. After a patient does out-toeing, the femoral head is placed more anteriorly.
Glute max is innervated by what nerve?
Inferior gluteal nerve
The superior band of iliofemoral ligament is taut with adduction or abduction?
Adduction
The inferior band of iliofemoral ligament is taut with adduction or abduction?
Abduction
The ischiofemoral ligament is taut with what motions at the hip?
Medial rotation, extension, and abduction
