Medial superior cluneal nerve entrapment neuropathy in teenagers: A report of two cases

Abstract

Medial superior cluneal nerve entrapment neuropathy causes pain radiating from the low back down to the posterior thigh. It tends to be misdiagnosed as a lumbar spine disorder. Patients in previous reports were in the middle or old age at the onset. Proposing simultaneous full flexion of the ipsilateral hip and knee joints as a provocation test, we present two cases of teenager females who spent long before diagnosis of their condition. Both of them had engaged in vigorous sports activities and completely recovered from the disability following local anaesthetic and corticosteroid injection at the trigger point. © 2002 Tohoku University Medical Press.
