Distribution of pain provoked from lumbar facet joints and related structures during diagnostic spinal infiltration.
This paper describes the patterns of pain induced from lumbar facet joints, from the posterior primary rami of L5, and from the medial articular branches of the posterior primary rami from T11 to L4 in patients undergoing diagnostic spinal infiltrations for chronic pain. No consistent segmental or sclerotomal pattern was found in 385 observations on 138 patients. Pain radiating to the buttock or trochanteric region occurred mostly from the L4 and L5 levels, while groin pain was produced from L2 to L5. The nerves supplying the facet joints gave rise to distal referral of pain significantly more commonly than the joints themselves.
