RATIONALE: Spinal cord infarction is one of the complications of epidural steroid injections (ESIs), but has only been reported in cervical vertebra by transforaminal injection and lumbar vertebra by transforaminal injection; and up to now, there is no reporting about spinal cord infarction caused by caudal injection. Here, we report a case. PATIENT CONCERNS: A 52-year-old man was admitted to our hospital. He was diagnosed as lumbar disc herniation in other hospital, and the patient suffered bilateral lower limb motor and sensory disorders after administration of caudal ESI...

Magnetization transfer (MT) contrast has been established as a marker of myelin integrity, and cervical spondylotic myelopathy is known to cause demyelination. Ten patients with clinical and magnetic resonance imaging (MRI) manifestations of cervical spondylotic myelopathy (CSM) were compared to the MRIs of seven historic healthy controls, using the magnetization transfer ratio (MTR) and Nurick scores as the primary metrics. Transverse slices through the intervertebral discs of the cervical spine were acquired using a gradient echo sequence (MEDIC) with and without an MT saturation pulse on a 3 Tesla Siemens Prisma scanner (TR = 300 ms, TEeff  = 17 ms, flip angle = 30°, in-plane resolution = 0...

RATIONALE: Cervical open-door laminoplasty can enlarge the volume of the cervical vertebral canal and thus has become an effective and safe treatment for multilevel cervical disc herniation and cervical stenosis. Some post-surgery complications exist, such as reduction of cervical alignment and local kyphosis. However, aggravation of cervical disc herniation at the surgical level during short-term follow-up has not been discussed. Additionally, spontaneous disappearance of herniated disc pulposus is a common phenomenon in the lumbar region but is relatively rare in the cervical region...

BACKGROUND: Anterior percutaneous endoscopic transcorporeal cervical discectomy (APETCD) is an alternative operation for cervical disc herniation. However, few reports have evaluated the biomechanical influence of tunnels on vertebrae. We compared biomechanical distinctions between intact and tunneled models to analyze the safety of APETCD based on a C2-T1 finite element(FE) model. METHODS: Two groups of C2-T1 FE models were simulated with C4 tunneled by two methods (A: with partial superior endplate excision, B: without partial superior endplate excision) and various tunnel diameters (6mm, 8mm, 10mm)...

Since the launch of cervical total disc replacement (CTDR) in the early 2000s, many clinical studies have reported better outcomes of CTDR compared to those of anterior cervical discectomy and fusion. However, CTDR is still a new and innovative procedure with limited indications for clinical application in spinal surgery, particularly, for young patients presenting with soft disc herniation with radiculopathy and/or myelopathy. In addition, some controversial issues related to the assessment of clinical outcomes of CTDR remain unresolved...

Study Design: A descriptive experimental study. Purpose: The purpose of this study was to describe the reliability and accuracy of palpable anterior neck landmarks (angle of the mandible, hyoid bone, thyroid cartilage, and cricoid cartilage) for the identification of cervical spinal levels in a slight neck-extended position as in anterior approach cervical spinal surgery. Overview of Literature: Standard, palpable anatomical landmarks for the identification of cervical spinal levels were described by Hoppenfeld using the midline palpable anterior structures (angle of the mandible [C2 body], hyoid bone [C3 body], thyroid cartilage [C4-C5 disc], cricoid cartilage [C6 body], and carotid tubercle [C6 body]) to determine the approximate level for skin incisions...

BACKGROUND: The concern of adjacent segment disease (ASD) has led to the development of motion-preserving technologies such as cervical disc arthroplasty (CDA). However, there is still controversy whether CDA is superior to anterior cervical decompression and fusion (ACDF) as to the incidence of ASD. The purpose of this study is to evaluate the rate of ASD between CDA and ACDF. METHODS: Systematic searches of all relevant studies through November. 2017 were identified from Cochrane Library, PubMed, Embase and CNKI...

BACKGROUND: Most of the current available cervical disc prostheses present a flat surface instead of an arcuate surface which is most similar to the morphology of cervical endplate. Therefore, we designed a novel prosthesis (Pretic-I, Trauson) based on the physiological curvature of the cervical endplate. Biomechanical evaluation of cervical disc replacement (CDR) with this novel prosthesis was performed and compared with the Prestige LP prosthesis. METHODS: Three motion segments of 18 cadaveric cervical specimens (C2-C7) were evaluated with a 75 N follower load...

INTRODUCTION: The patient was referred to an outpatient physical therapy clinic for lumbar radiculopathy by a primary care physician and subsequently referred for imaging due to suspicion of cervical myelopathy. The case highlights the clinical reasoning of the physical therapist differentiating between lumbar stenosis, cervical myelopathy, and upper cervical instability. To the author's knowledge, this is the only case report in the literature to describe the mechanism that could underpin a false positive Sharp-Purser test (SPT)...
