Cervical radiculopathy is characterized by compression of the roots of the nerve. When conservative treatment fails and symptoms persist or increase in severity, surgical treatment is considered. Anterior cervical discectomy with or without fusion is regarded as the standard treatment for cervical disk herniation. Recently, there is an evolving trend in spinal surgery towards less invasive techniques. Nucleoplasty is a minimally invasive technique in which radiofrequency technology is used for percutaneous decompression...

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...

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...

BACKGROUND: The anterior approach to lumbar spine surgery has grown in popularity in the past few years; spinal fusion of the last two lumbar levels is often required. While there are alternatives to bone grafting 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...

INTRODUCTION: Hidden zone foraminal herniations are among the more rare forms of herniations. As exploration is difficult, and there is a close relationship between the nerve root and pedicle, many surgical approaches have been proposed. The aim of this study was to describe downward laminotomy as a new approach to these herniations. MATERIALS AND METHODS: A downward laminotomy technique was used in 5 cases with hidden zone foraminal disk herniation with no extension to the intervertebral disk space...

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...

Schwann cells (SCs) are promising candidates for transplantation-strategies in the central nervous system by promoting axonal regeneration. The dog represents a translational model for human spinal cord injury (SCI) for studies with new repair strategies after intervertebral disk herniation (IVDH). To overcome the necessity for an additional surgical procedure, for the first time a protocol for isolation, and purification of canine SCs from spinal-nerve-biopsies during standard hemilaminectomy in IVDH affected paraplegic dogs for potential transplantation was developed...
