1

What can cause femoral neuropathy?

- hip or pelvic fractures
- masses within the iliacus (such as hematoma)

2

Femoral neuropathy is a recognized complication of what?

- childbirth
- hip replacement
- abdominal and pelvic surgery - laparoscopy
- inguinal lymph node biopsy
- femoral nerve block
- femoral artery puncture

3

What type of patients occasionally develop spontaneous femoral neuropathies?

diabetes mellitus

4

Patients with significant femoral neuropathies develop weakness in what muscle groups?

quadriceps (except for the adduction portions which are innervated by the obturator nerve)

5

Other than quadriceps muscle weakness what is another common symptom?

sensory loss over the anterior thigh and most of the medial thigh, extending down to the medial shin and sometimes to the arch

6

Sensory loss occurs along the distribution of which nerve?

saphenous

7

What reflex generally decreases or becomes unobtainable?

knee jerk

8

What produces symptoms of the syndrome gonyalgia paresthetica?

Damage to the infrapatellar branch of the saphenous nerve due to mild trauma or knee operations

9

Describe the symptoms of gonyalgia paresthetica

sensory loss in a several centimeter diameter patch below the knee with intermittent lancinating pains

10

A reduced or absent ______ sensory response will also help confirm the presence of a femoral neuropathy

saphenous

11

What is the prognosis for incomplete femoral nerve injuries?

good

12

What factor is associated with prognosis?

estimate of axonal loss
