X-linked hypophosphataemic rickets (XLHR) is a genetic disorder resulting from a genetic mutation in the PHEX gene. This may cause ossification of soft tissue structures risking spinal cord compression. We present the first known case of cervical dural calcification secondary to XLHR to cause myelopathic symptoms due to cord compression.

A 61-year-old gentleman was admitted with progressive symptoms of cervical myelopathy. An MRI performed showed severe compression from C3-6 with cord signal changes. He was offered surgical intervention but the operation had to be delayed because of worsening abdominal distension. X-rays performed showed a severely dilated colon measuring >12 cm. A CT did not show any obstructive cause. He was managed conservatively for more than 2 weeks but did not improve. As his symptoms continued to worsen, a decision was made to proceed with a C3-6 posterior decompression and fusion, despite the theoretical risk of bacterial translocation predisposing him to infection...

BACKGROUND AND PURPOSE: T2*-weighted imaging provides sharp contrast between spinal cord GM and WM, allowing their segmentation and cross-sectional area measurement. Injured WM demonstrates T2*WI hyperintensity but requires normalization for quantitative use. We introduce T2*WI WM/GM signal-intensity ratio and compare it against cross-sectional area, the DTI metric fractional anisotropy, and magnetization transfer ratio in degenerative cervical myelopathy. MATERIALS AND METHODS: Fifty-eight patients with degenerative cervical myelopathy and 40 healthy subjects underwent 3T MR imaging, covering C1-C7...

Osseous-associated cervical spondylomyelopathy in dogs is characterized by both static and dynamic spinal cord compression; however, standard MRI methods only assess static compression. In humans with cervical spondylotic myelopathy, kinematic MRI is commonly used to diagnose dynamic spinal cord compressions. The purpose of this prospective, analytical study was to evaluate kinematic MRI as a method for characterizing the dynamic component of osseous-associated cervical spondylomyelopathy in dogs. We hypothesized that kinematic MRI would allow visualization of spinal cord compressions that were not identified with standard imaging...

PURPOSE: Clinical studies have shown that endplate Modic change in the cervical spine and intramedullary high signal intensity often occurs simultaneously. We aimed to investigate whether there is a correlation between Modic change and intramedullary high signal intensity, and to explore the possible risk factors. MATERIALS AND METHODS: In total, 133 patients with cervical spondylotic myelopathy treated at the First Affiliated Hospital of Nanjing Medical University between May 2009 and March 2013 were enrolled in the study...

Degenerative cervical myelopathy (DCM) is a common cause of spinal cord dysfunction that confronts clinicians on a daily basis. Research performed over the past few decades has provided improved insight into the diagnosis, evaluation, and treatment of this disorder. We aim to provide clinicians with an update regarding the state of the art in DCM, focusing on more recent research pertaining to pathophysiology, natural history, treatment, consideration of the minimally symptomatic patient, surgical outcome prediction, and outcome measurement...

INTRODUCTION: Osteochondromas are usually found in the extremities and are rarely seen in the spine. They are most commonly found in the posterior elements of the spine, and intraspinal extension is uncommon. Compressive myelopathy as a presentation of vertebral osteochondroma in a child is a rare entity. METHODS: We report a case of vertebral osteochondroma arising from the lamina of C3 vertebra, presenting with features of compressive myelopathyin a 15 year old boy...

Os odontoideum is a separate odontoid process from the body of the axis. It is the most common anomaly of the odontoid process. Patients with this condition can be asymptomatic or present with a wide range of neurological dysfunctions. It may cause cervical instability, atlantoaxial dislocation and myelopathy. This anomaly can mimic Type I and II odontoid fractures. There is a role for conservative treatment of an asymptomatic incidentally found, radiologically stable and non-compressive os odontoideum. However, surgical treatment has a definitive role in symptomatic cases...

Osteochondromas are the most common benign tumors of the bone. They occur in young adolescent patients and are frequently located in the metaphyses of the long bones; they do not grow after skeletal maturity. The incidence of osteochondroma in the spine is reported to be rare. Moreover, patients with spinal osteochondroma who develop symptoms of myelopathy are extremely rare. We report the case of an 8-year-old girl who experienced myelopathy due to spinal compression of the cervical osteochondroma. This case suggests that if a cartilage cap is observed on the spinal canal with magnetic resonance imaging (MRI), the tumor may extend to the spinal canal, resulting in neurologic dysfunction...

OBJECTIVE In patients with cervical spondylotic myelopathy (CSM), the motor system may undergo progressive functional/structural changes rostral to the lesion, and these changes may be associated with clinical disability. The extent to which these changes have a prognostic value in the clinical recovery after surgical treatment is not yet known. In this study, magnetic resonance spectroscopy (MRS) was used to test 2 primary hypotheses. 1) Based on evidence of corticospinal and spinocerebellar, rubro-, or reticulospinal tract degeneration/dysfunction during chronic spinal cord compression, the authors hypothesized that the metabolic profile of the primary motor cortices (M1s) and cerebellum, respectively, would be altered in patients with CSM, and these alterations would be associated with the extent of the neurological disabilities...

In contrast to other levels of upper disc spaces, the Luschka joints are usually absent at the C7/T1 disc space. Therefore, it has been reported that the C7/T1 disc herniation is prone to herniate laterally rather than centrally. In this manuscript, we describe an extremely rare central-type disc herniation at the C7/T1 level presented with myelopathy. A 76-year-old man presented with a 20-day history of progressive gait disturbance. Physical examination revealed bilateral lower extremity hyperreflexia and mild foot numbness with no upper extremity motor weakness or sensory disturbance...

The age related spondylotic changes may result in direct compressive and ischemic dysfunction of the spinal cord known as cervical spondylotic myelopathy (CSM). Symptoms often develop insidiously and are characterized by neck stiffness, unilateral or bilateral deep aching neck, arm and shoulder pain, and possibly stiffness or clumsiness while walking. The management available in current mainstream medicine is not satisfactory. Various Ayurvedic treatments have been in use for these manifestations. We present a case of CSM, which was treated with a combination of Panchakarma procedures and Ayurvedic oral drugs...

The aim of this study was to reveal the sensitivity and responsiveness of contact heat evoked potentials (CHEPs) to assess cervical spondylotic myelopathy (CSM). A total of 81 patients with clinically and radiologically confirmed spinal cord compression were reviewed. All patients underwent full clinical examinations with combined recordings of segmental CHEPs and somatosensory evoked potentials (dSSEPs) compared with healthy controls. Cross-sectional area, maximal canal compression, and maximal spinal cord compression were determined based on T2-weighted MRI...

PURPOSE: Posterior cervical laminectomies and laminoplasties are common treatments for cervical spondylotic myelopathy. However, recent studies demonstrated that positional spinal cord compression occurred after cervical laminectomies and caused postoperative progressive myelopathy. Although there were no such reports after laminoplasties, we report two cases in which symptomatic extraordinary positional spinal cord compression occurred after laminoplasties in this paper. METHODS: This study included two patients who showed progressive myelopathy: one case after a laminectomy following failure of a single-door laminoplasty and one case after a double-door laminoplasty without interlaminar spacers...

STUDY DESIGN: Retrospective analysis. PURPOSE: To compare results of laminectomy in multisegmental compressive cervical myelopathy (CSM) with lordosis versus segmental kyphosis. OVERVIEW OF LITERATURE: Laminectomy is an established procedure for decompression in CSM with cervical lordosis. However in patients with segmental kyphosis, it is associated with risk of progression of kyphosis and poor outcome. Whether this loss of sagittal alignment affects functional outcome is not clear...

STUDY DESIGN: A retrospective study. OBJECTIVE: To identify preoperative risk factors causing cervical fifth nerve root palsy (C5 palsy) after laminectomy and fusion (LF). SUMMARY OF BACKGROUND DATA: It is well known that postoperative C5 palsy is not rare after cervical surgery. Although there remains controversy, C5 palsy is considered to be more common in patients who had LF than in those who had laminoplasty. However, the reason for the higher incidence of C5 palsy in patients with LF has been poorly understood...
