Entrapment of the Fifth Lumbar Spinal Nerve by Advanced Osteophytic Changes of the Lumbosacral Zygapophyseal Joint: A Case Report
نویسندگان
چکیده
A 54-year-old female patient had a 6-year history of backache and left sciatica. Five years earlier, she had undergone surgery in another hospital for left L4-5 disc herniation. Computed tomography revealed the ossified wall that enclosed the left L5 nerve root. There were also osteophytic changes in the left L5-S zygapophyseal joint. These osteophytes developed rostrally, along the left L5 nerve root, throug h the intervertebral foramina. We performed decompression surgery for the left L5 nerve root, and surgery resulted in symptomatic relief. We experienced a rare clinical presentation of osteophytic formation, with a specific configuration in relation to the nerve root. Surgeons should be aware of entrapment of the lumbar spinal nerve by advanced osteophytic changes occurring in the zygapophyseal joint after lumbar surgery.

OBJECT Because lumbar magnetic resonance (MR) imaging fails to identify a treatable cause of chronic sciatica in nearly 1 million patients annually, the authors conducted MR neurography and interventional MR imaging in 239 consecutive patients with sciatica in whom standard diagnosis and treatment failed to effect improvement. METHODS After performing MR neurography and interventional MR imag...
متن کاملCase Report: An Uncommon Anatomical Variation of the Sciatic Nerve
The sciatic nerve is a largest single nerve of the lumbosacral nervous plexus. This nerve innervates all muscles of the leg and foot as well as the flexor muscles of the knee joint. Many variations in the direction and relations of sciatic nerve were described. The current case report presented a thick septum situated posterior to the sciatic nerve and its branches spread throughout the back of...
متن کاملMorphological changes of lumbar spinal neurons after sciatic nerve transection in neonate rats
Axotomy of the sciatic nerve have been documented to cause neuronal loss, especially in newborn rats. Few works have focused on time course of neuronal loss and the type of cell death, which occurs after axotomy. Forty rat pups were anesthetized by hypothermia and the right sciatic nerve transected at five days of their age and the left side was used as control. The operated animals were sacrif...

Background: The changes in motor control after the use of a supportive belt can contribute to the understanding of its effects on performance. The aim of this study is to quantify motion pattern values relative to the spinal column during the use of a lumbosacral belt.Methods: For fifty healthy female volunteers, the range of motion, maximum isometric torque and changes of phase angle of maximu...
