Lumbar plexopathy following instrumented posterior lumbar interbody fusion: a complication with use of Hohmann’s retractor

摘要

IntroductionA series of 12 patients in our centre following single level instrumented posterior lumbar interbody fusion at L4–L5 developed unexplainable motor weakness in the proximal lumbar nerve roots (L2, L3) and numbness of the whole limb, a clinical picture resembling lumbar plexopathy. Even though lumbar plexopathy has been reported following gynaecological procedures and in transpsoas interbody fusion surgeries, there is no literature reporting this complication following conventional instrumented posterior lumbar interbody fusions.
