Diabetic Lumbosacral Radiculoplexus Neuropathy as an Early Onset Postoperative Complication After Posterior Lumbar...

Diabetic amyotrophy, also known as diabetic lumbosacral radiculoplexus neuropathy (DLRN), is a condition associated with sudden pain apparition and progressive distal extremities weakness leading to ambulatory status. A wide range of causes and pathologies may be involved, rendering the diagnosis challenging. Uncontrolled type 2 diabetes mellitus (T2DM) can be a trigger factor for such disorders. Here, we present the case of a 71-year-old patient with chronic left quadriceps weakness and atrophy, accompanied by radiculopathy, who underwent a single-level posterior lumbar fixation and decompression. The patient with a history of T2DM postoperatively showed immediate relief regarding the pain and started the rehabilitation protocol on the second post-op day. One month postoperatively, he presented with accusations of sensory impairment, motor weakness, and pain.
