SCIATIC NERVE INJURY:
Incidence: Frequent
Sciatic nerve injury is commonly associated with fractures of the ilium or proximal femur.
The nerve is commonly traumatized by retraction during hip and proximal femur surgery
and by improper intramuscular injections into the semimembranosus and semitendinosus muscles.
The sciatic nerve may be electrically stimulated at the lateral proximal femur and at the
stifle, and recordings taken from the various extensor and flexor muscles to determine nerve integrity.
If the nerve is severed and the site of injury is known, surgical exploration and repair
may be indicated. Proximal sciatic nerve injuries in larger dogs have a poor prognosis if the
nerve is severed, because of the distance the nerve must regenerate for reinnervation of distal
musculature. |
