Redundant Nerve Roots (RNRs) is an uncommon clinical condition characterized by a tortuous, serpentine, large and elongated nerve root of the cauda equina. To our knowledge, most cases of RNRs are associated with lumbar stenosis, and RNRs associated with lumbar disc herniation has not been reported until now. Here we present a rare case of unusual RNRs associated with lumbar disc herniation mim...

a 25-year old man presented with chronic low back pain for about 5 years due to mild congenital lumbar kyphosis (l1-l3 25° with congenital posterior wedge vertebra l2). preoperative neurologic examination was normal. after posterior spinal fusion and instrumentation with moderate curve correction, the patient gradually developed the symptoms and signs of cauda equina syndrome due to intraoperat...

BACKGROUND There are many different reasons why patients could be experiencing pain in the gluteal area. Previous studies have shown an association between radicular low back pain (LBP) and gluteal pain (GP). Studies locating the specific level responsible for gluteal pain in lumbar disc hernias have rarely been reported. METHODS All patients with lumbar disc herniation (LDH) in the Kanghua h...

Lumbar disc herniation is one of the most common medical and surgical problems all over the world. The vast majority of lumbosacral radiculopathies are caused by paracentral herniation. However, Hood reported that far lateral lumbar disc herniation (FLLDH) accounts for 2.8 – 10% of all disc herniations. Over 75% of FLLDHs occur at the L3 –L4 and L4 – L5 levels. In addition, FLLDH presents a cli...

The traditional view that the etiology of lumbar disc herniation is primarily due to age, gender, occupation, smoking and exposure to vehicular vibration dominated much of the last century. Recent research indicates that heredity may be largely responsible for the degeneration as well as herniation of intervertebral discs. Since 1998, genetic influences have been confirmed by the identification...

Studies on recurrent disc herniation quote rates of recurrence without regard to the times of recurrence and the influence of longer follow-up. Our objective was to assess the use of survival analysis to measure the rate of revision after lumbar microdiscectomy. We undertook a retrospective analysis of the hospital records of 993 patients who underwent lumbar microdiscectomy over a period of te...

  Background :The incidence of recurrence in patients undergoing primary discectomy due to lumbar disc herniation (LDH), is regularly reported as 5-15%. In this study we aimed to evaluate surgical outcome of instrumented transforaminal lumbar interbody fusion (TLIF) in the patients suffering from recurrent LDH.   Methods : We retrospectively studied 51 patients (30 female, 21 male) from August ...
