Objective: Lumbar intervertebral disk herniation (LDH) is considered one of the major risk factors for lower back pain, mainly caused by irritation of a spinal nerve or its root. One of the genes related to pain perception is SCN9A, which encodes the voltage gated sodium channel NaV1.7, a key molecule involved in peripheral pain processing. It had been presented before that a common polymorphism within SCN9A (rs6746030: G > A, R1150W) might influence nociception in the general population...

PURPOSE: This work describes a minimally invasive damage model for ovine lumbar discs via partial nucleotomy using a posterolateral approach. METHODS: Two cadavers were dissected to analyze the percutaneous corridor. Subsequently, 28 ovine had their annulus fibrosus punctured via awl penetration under fluoroscopic control and nucleus pulposus tissue removed via rongeur. Efficacy was assessed by animal morbidity, ease of access to T12-S1 disc spaces, and production of a mechanical injury as verified by discography, radiography, and histology...

Lumbar disk herniation is common. Because of the posterior longitudinal ligament, migration usually occurs into the ventral epidural space. Rarely, fragments migrate into the dorsal epidural space. A 57-year-old man presented with lower back pain and weakness on right hip flexion and right knee flexion. He had lower back pain 1 day previously and received a transforaminal epidural block at a local hospital. The next day, he reported weakness of the right lower extremity. Lumbar spine magnetic resonance imaging revealed a dorsal epidural lesion with compression of the thecal sac at L2-3...

Physicians are often faced with managing difficult conditions such as chronic lower back pain. Intervertebral disk herniation typically occurs horizontally, leading to impingement of the spinal cord which can potentially cause radicular symptoms or other spinal cord pathologies; however, disk herniations can also occur vertically and extend through the endplate of an adjacent cranial or caudal vertebra: a phenomenon known as a Schmorl's node. Although Schmorl's nodes can be seen in many asymptomatic individuals, they can be a cause of degenerative disk disease and low back pain...

Malignant peripheral nerve sheath tumors (MPNST) are very rare and are frequently localized in the buttocks, thigh, arm, or paraspinal region; one variant is the malignant Triton tumor, with rhabdomyosarcomatous differentiation. The authors present a challenging differential diagnosis of a sciatic pain and foot drop in a woman with history of lumbar disk herniation, which was found to be caused by a Triton tumor of the sciatic nerve. She underwent surgical excision, followed by radiation and chemotherapy. Malignant Triton tumor cases have rarely been described and reported in the literature...

STUDY DESIGN: Randomized controlled trial. PURPOSE: We compared the disability and functional outcome after conservative treatment with prolonged physiotherapy versus early surgical intervention in patients with lumbar disk herniation. OVERVIEW OF LITERATURE: Lumbar disk herniation is one of the most common causes of job-related disability in individuals less than 45 years old. Conservative treatment is the initial pathway for the majority of patients but the duration of conservative treatment remains debatable and the adverse effects of prolonged conservative treatment are still unclear...

BACKGROUND: To limit epidural fibrosis and prevent scar formation/nerve tethering that may contribute to chronic postoperative pain; some surgeons have utilized epidural autologous fat grafts following lumbar microdiscectomy. METHODS: We investigated the correlation between post-microdiscectomy epidural scarring [including select magnetic resonance imaging (MRI) studies] and clinical outcomes in 36 patients operated for symptomatic. MRI documented L4-L5 and L5-S1 disk herniations with (18 patients) and without (18 patient) the application of free fat grafts...

INTRODUCTION: Extraforaminal disk herniation (EDH) accounts for 3-11% of all disk herniations. Despite the heterogeneity of spinal procedures, there is a paucity of literature comparing the outcomes from different surgical approaches. METHODS: We performed a systematic review and meta-analysis of available literature on EDHs. We compared patients undergoing open surgery (OS) with those undergoing minimally invasive surgery (MIS) approaches, including tubular microscopic, percutaneous endoscopic, and micro-endoscopic...

The present study aimed to investigate the technical feasibility of percutaneous endoscopic mini-hemilaminectomy via a uniportal approach, and to evaluate the possibility of decompression and endoscopic examination of the thoracic and lumbar spinal canals in small dogs during such procedures. Fresh canine cadavers of mixed-breed dogs (n=7) were used in this study. Following injection of a barium and agarose mixture (BA-gel) to stimulate intervertebral disc herniation, percutaneous endoscopic mini-hemilaminectomy was performed using a lateral approach to the thoracic and lumbar vertebrae...

The aim of this study was to analyze the correlation between high-intensity zone (HIZ) on magnetic resonance imaging (MRI) of a lumbar disc and positive pain response assessed by discography for the diagnosis and treatment of discogenic low back pain (LBP). Thirty-seven patients aged 21 to 59 years with chronic LBP but without any neurological symptoms or lumbar disc herniation who underwent MRI and subsequent discography were included in this study. During discography, concordant pain was regarded as positive, whereas discordant pain and no pain were regarded as negative...

BACKGROUND: The anterior approach to lumbar spine surgery has grown in popularity in the past few years; spinal fusion of the last 2 lumbar levels is often required. Although alternatives to bone grafting are available, including recombinant human bone morphogenetic protein 2 or bone substitutes, only cancellous autologous bone has all the required factors for bone growth. To avoid the use of bone substitutes, remote iliac crest bone harvesting remains the gold standard. However, this technique may lead to some unfavorable outcomes...

Sciatic nerve compression due to a ganglion cyst around the posterior aspect of the hip joint is not commonly described in literature. We report a rare case of a 63-year-old man with a ganglion cyst around his hip joint, who presented with symptoms of sciatica. After excision of the cyst, the patient was symptom free. A high index of clinical doubt and detailed clinical examination is required for non-palpable cystic lesions in close proximity to the sciatic nerve in patients presenting with symptoms of sciatica and in patients with concomitant of lumbar disk herniation...

Low back pain is the most common complaint expressed by adult patients in the primary care setting, and the incidence of low back pain in adolescents is rising. Adolescents who are involved in athletics most commonly suffer from spondylolysis, spondylolisthesis, mechanical low back pain, and herniated disks, whereas adult athletes most commonly suffer from lumbosacral strain and herniated or degenerative disks. Initial nonsurgical management aims to reduce inflammation and noninvasively strengthen damaged tissues...

Lumbar disk herniation, degenerative disk disease, and spondylolysis are the most prevalent lumbar conditions that result in missed playing time. Lumbar disk herniation has a good prognosis. After recovery from injury, professional athletes return to play 82% of the time. Surgical management of lumbar disk herniation has been shown to be a viable option in athletes in whom nonsurgical measures have failed. Degenerative disk disease is predominately genetic but may be accelerated in athletes secondary to increased physiologic loading...

We present a case of a 15-year-old male with history of back pain and bilateral lower limb radiculopathy due to fall. The magnetic resonance imaging scan showed disc bulge at L2-L3 level causing compression on contained nerve roots. In this case, computed tomography scan was indispensable for diagnosis and classification of the vertebral apophyseal fracture and to guide appropriate further management. Apophyseal ring fracture is an uncommon cause of back pain with radiculopathy in adolescents and athletes. High degree of suspicion is necessary to differentiate these injuries from disc herniation so as to further guide appropriate conservative or surgical management...
