In degenerative lumbar spinal disease with nerve root compression, the L5 and S1 nerve roots are the most often affected and the L3 nerve root is involved infrequently. The purpose of this study was to investigate the characteristics of L3 nerve root radiculopathy. ⋯ L3 radiculopathy was characterized by various lower limb pain and neurologic deficit. Selective nerve root injection was effective for most patients. In elderly patients who do not respond to treatment for hip and/or knee joint diseases, L3 nerve root radiculopathy should be considered as the cause of lower limb pain.

Several catheter problems have been reported as causes of baclofen pump malfunction; however, a tangled catheter has never been described. ⋯ Although the exact mechanism of this complication is unknown, the friction-compression of the catheter against the iliac bone may be the cause. Implanting the pump away from the bony formation may avoid catheter entanglement.
