OMM Flashcards
What nerve can be damaged by fibular head dysfunction and what clinical presentation will it have?
Common fibular (peroneal) nerve courses just behind the head of the fibula. Damage to common fibular nerve affects function of most anterolateral muscles of the leg causing foot drop.
What is the difference between seated and standing flexion tests?
Seated flexion plants the ischial tuberosities on the table so that the sacrum does the moving. Positive findings indicate dysfunction most likely assoc. with the sacrum.
Standing allows motion of the pelvis and is therefore more of an indication of pelvis or innominate dysfunction than sacral.
A bilateral sacral extension rotates about what axis?
Middle transverse axis
Describe the motion that occurs about the sacral axes.
Superior transverse: respiratory and craniosacral motion
Middle transverse: postural motion
Inferior transverse: innominate rotation
Obliques: dynamic motion
With a sacral rotation about an oblique axis, what will be the result of the seated flexion test and why?
Seated flexion test will be positive on the opposite side of the axis for sacral rotation about an oblique axis.
The sulcus moves anteriorly on the ilium on the opposite side of the axis and this causes sacroiliac dysfunction.
What nerve innervates the interossei muscles of the hand?
Ulnar nerve
Musculocutaneous nerve originates from what cord of the brachioplexus?
Lateral cord
Radial nerve originates from which cord of the brachial plexus?
Posterior cord
Axillary nerve originates form which cord of the brachial plexus?
Posterior cord
Nerve innervation of teres major
Axillary nerve
Innervation of infraspinatus
Suprascapular nerve
Innervation of supraspinatus
Suprascapular nerve
What muscles are innervated by Dorsal Scapular nerve?
Levator scapulae
Rhomboids
What nerve is commonly damaged with shoulder dislocations?
Axillary nerve because it courses behind the humeral head and anterior/inferior dislocations stretch the nerve and damage it.
In a classic ankle sprain, what is the associated dysfunction of the fibular head?
Classic sprains plantarflex, invert, and internally rotate the foot. This would cause a posterior fibular head.
What articulations exist between the tibia and fibula?
There are 2 articulations:
Lower: syndesmotic
Upper: synovial
