Introduction: Abnormalities of the lumbar nerve tract caused by congenital variations or high nerve root take-off angles are difficult to visualize. Diffusion-weighted magnetic resonance neurography (DW-MRN) has recently been introduced for imaging of the lumbosacral region. The aims of this study were to identify lumbar nerve tract abnormalities caused by congenital variation or a high nerve root take-off angle using DW-MRN and to assess the diagnostic value of this imaging modality.

Bow hunter syndrome (BHS) is a rare vascular phenomenon of vertebrobasilar insufficiency caused by dynamic stenosis of the vertebral artery (VA) by osteophytes, fibrous bands, or disk herniation with neck rotation. We present a rare case of a patient with bilaterally patent VAs on neutral imaging and bilateral dynamic compression of VA with left head rotation. Provocation tests are critical toward understanding dynamic pathophysiology of BHS because normal neutral vascular imaging does not preclude diagnosis of BHS. Read More

Fenestration offers the advantages of prophylaxis without the need for specialized instrumentation and imaging. Currently there is a lack of equipoise regarding the efficacy of fenestration relative to decompression for treatment of acute canine intervertebral disk herniation; most veterinary spinal surgeons do not consider the 2 procedures equivalently efficacious. Therapeutic fenestration should perhaps be given greater consideration, especially if advanced imaging shows only mild to moderate spinal cord compression or there are restrictions on the duration of surgery, when it might be better to spend the time on fenestration rather than decompression.

Once decompressive surgery has been elected, the approach that maximizes the likelihood of gaining access to the herniated material for complete removal should be chosen. In most cases, a procedure that optimizes access to the ventrolateral aspect of the spinal cord will be advantageous but it is important to tailor the details of the surgical procedure to suit individual patients. Decompressive surgery for chronic (type II) herniations will frequently demand a ventral approach with partial corpectomy. Read More

Acute herniation of nondegenerate nucleus pulposus material is an important and relative common cause of acute spinal cord dysfunction in dogs. Two types of herniation of nondegenerate or hydrated nucleus pulposus have been recognized: acute noncompressive nucleus pulposus extrusion (ANNPE) and acute compressive hydrated nucleus pulposus extrusion (HNPE). Spinal cord contusion plays an important role in the pathophysiology of both conditions. Read More

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. Read More

Background: The incidence of thoracic disk herniation is estimated to be 1000 to 1,000,000. Upper thoracic disk herniation is an exceedingly rare pathology with unique neurologic features. We report a case of a young patient who presented with Horner syndrome caused by a T1-T2 disk herniation. Read More

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. Read More

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. Read More

Study Design: Prospective study.
Objective: The purpose of this study was to compare the long-term clinical and radiologic outcomes of hybrid surgery (HS) and 2-level anterior cervical discectomy and fusion (2-ACDF) in patients with 2-level cervical disk disease.
Summary Of Background Data: In a previous study with a 2-year follow-up, HS was shown to be superior to 2-ACDF, with a better Neck Disability Index (NDI) score, less postoperative neck pain, faster C2-C7 range of motion (ROM) recovery, and less adjacent ROM increase. Read More

Objective: To compare the clinical outcome after Discover arthroplasty versus anterior cervical discectomy and fusion (ACDF) in patients treated for symptomatic single-level cervical disk disease.
Summary Of Background Data: ACDF is still the gold standard for surgical treatment of cervical spine degenerative disk disease. Read More

Purpose: To evaluate the influence of a nonrigid fixation system and posterior lumbar interbody fusion on adjacent intervertebral disc degeneration by using MRI analysis of lumbar nucleus pulposus volume for single-level lumbar disc herniation.
Materials And Methods: We selected 112 patients who underwent nonrigid fixation (17 men and 44 women) or posterior lumbar interbody fusion (13 men and 38 women) for this retrospective study. Based on the T2-weighted magnetic resonance imaging (MRI) scans taken preoperatively, and 6, 12, and 24 months after surgery, the nucleus pulposus in the upper segments of the operated level was considered an ellipsoid, and their volumes were measured respectively and then compared between the two groups.

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. Read More

Background And Study Aims: The technique and instrumentation of percutaneous endoscopic lumbar diskectomy (PELD) have significantly improved. Thus its indications have been gradually expanding. Down-migrated disk, in particular, is regarded inaccessible by rigid instrumentation due to poor visualization and limited accessibility. Read More

Background: Prognostic tools to predict early postoperative motor function recovery (MFR) after thoracolumbar intervertebral disk herniation (IVDH) in paraplegic dogs represent an opportunity to timely implement novel therapies that could shorten recovery times and diminish permanent neurological dysfunctions.
Hypothesis: Fractional anisotropy (FA) values obtained using diffusion tensor imaging have a higher prognostic value than a lesion extension ratio in T2-weighted images (T2W-LER) and clinical assessment of deep pain perception (DPP) for MFR.
Animals: Thirty-five paraplegic dogs with diagnosis of acute or subacute thoracolumbar IVDH. Read More
