A 48 year aged man has trouble walking. At his physician's office, he is asked to stand on his right foot and his left hip drops. Which of the following nerves is most likely damaged, causing his problem
A. Left inferior gluteal.B. Left superior gluteal.
C. Right superior gluteal.
D. Right inferior gluteal.
Answer.
C. Right superior gluteal
- In this
patient, the right superior gluteal nerve is damaged, leading to failure of
abductor mechanism of gluteus medius. There is also the failure of muscle to
cause an upward lift of left hip, when the patient is asked to stand on his
right foot.
- Normally the
superior gluteal nerve leads to pelvic stability while a person stands on a
single foot, by elevating the opposite hip- the job being performed by gluteus
medius
