Final answer:
Option C. The confirmation of a common fibular nerve injury includes the presence of footdrop and loss of cutaneous sensation in the lateral and anterior aspects of the lower leg. The anterior aspect of the upper leg is not related to fibular nerve injury but the femoral nerve, and motor weakness of lower extremities is less specific for this diagnosis.
Step-by-step explanation:
The common fibular nerve can be injured during surgical procedures like a laparoscopic-assisted vaginal hysterectomy. To confirm the diagnosis of a common fibular nerve injury, you should look for specific clinical findings. There are two main confirming findings:
- Footdrop: This is characterized by difficulty lifting the front part of the foot, which can cause the foot to drag on the ground when walking. This condition happens due to weakness or paralysis of the muscles that lift the foot.
- Loss of cutaneous sensation in the lateral and anterior aspect of the lower leg: Because the fibular nerve provides sensory innervation to this area, damage to the nerve can lead to numbness or a decrease in sensation.
Option B is incorrect because the anterior aspect of the upper leg is innervated by the femoral nerve, not the fibular nerve. Option D might result from a fibular nerve injury but is less specific as it could also indicate other neurological conditions.
