INTRODUCTION: Childhood angular kyphosis is rare, as most children are affected by a mixed kyphotic and scoliotic deformity. Published series involving a mix of kyphosis and kyphoscoliosis, pediatric and adult, congenital and acquired cases are almost exclusively authored by orthopedic surgeons, suggesting that (pediatric) neurosurgeons are not involved. CASE SERIES: We present five cases that illustrate the spectrum of angular kyphosis, and these were treated by a multidisciplinary team including child neurologist, orthopedic surgeon, and pediatric neurosurgeon as complementary partners...

OBJECTIVE: Both females and the elderly have been identified as vulnerable populations with increased injury and mortality risk in multiple crash scenarios. Particularly in frontal impacts, older females show higher risk to the chest and thorax than their younger or male counterparts. Thoracic geometry plays a role in this increase, and this study aims to quantify key parts of that geometry in a way that can directly inform human body models that incorporate the concept of person age...

STUDY DESIGN: We retrospectively reviewed 100 patients who were posterior stabilized without graft fusion. Using the Sextant system, 22 patients underwent minimally invasive short-segment 4-pedicle screw fixation (MIF4) and 39 patients underwent minimally invasive short-segment combined with intermediate screws fixation, that is, 6-pedicle screw fixation (MIF6). The conventional open posterior short-segment 4-pedicle screw fixation (OPF4) technique was used in 39 patients. OBJECTIVE: To evaluate the feasibility, safety, and efficacy of percutaneous pedicle screw fixation using the Sextant system in the treatment of traumatic thoracolumbar fractures compared with the conventional open posterior short-segment pedicle screw fixation technique...

Ependymomas are the most common gliomas of the conus and lower cord, with the cervical cord being the second most common location. These tumors can extend upward 3-4 vertebra, and some ependymomas can extend up over 15 segments. Depending on many factors, such as tumor size, lateralization, kyphotic deformity, and lordosis state, there are several posterior surgical options, including laminectomy, laminectomy and lateral mass screw-plate, and laminoplasty. In this study, we discuss a case of intradural intramedullary cervicothoracic ependymoma with long-segmental localization, as well as the general surgical principles of its excision with step-by-step demonstrative figures...

Zhen Zhang, Zhen Liu, Zezhang Zhu, Yong Qiu
BACKGROUND: A previous study reported a high prevalence of spinal epidural lipomatosis (SEL) in patients with Scheuermann kyphosis (SK) and suggested that it may play a role in the pathogenesis of this disease. According to our observation, however, SEL occurs in other spinal kyphotic deformities as well. The aim of this study was to test the hypothesis that SEL commonly occurs in patients with different types of kyphotic deformities as a secondary intraspinal disorder. METHODS: MR images of 16 patients with congenital kyphosis (CK), 40 patients with SK, 13 patients with tuberculotic kyphosis (TK), and 69 age- and sex-matched controls were retrospectively evaluated...

OBJECTIVE Although there is increasing recognition of the importance of cervical spinal sagittal balance, there is a lack of consensus as to the optimal method to accurately assess the cervical sagittal alignment. Cervical alignment is important for surgical decision making. Sagittal balance of the cervical spine is generally assessed using one of two methods; namely, measuring the angle between C-2 and C-7, and drawing a line between C-2 and C-7. Here, the best method to assess sagittal alignment of the cervical spine is investigated...

Osteoporotic fractures with severe kyphosis and neurologic deficits often require decompression and stabilisation. To reduce the risk of procedure-related complications, single-stage posterolateral vertebrectomy and a 360-degree fusion can be performed. An adequate reduction of kyphotic deformity through this approach has not been reported. The aim of this study is to investigate the efficacy of kyphotic deformity reduction by this approach in osteoporotic situation. A retrospective analysis and chart review was performed for 10 consecutive patients who underwent posterolateral decompression and posterior vertebrectomy with dorsal mesh stabilisation and reduction of kyphotic deformity...

BACKGROUND: Cervical spinal tuberculosis is relatively common in some developing countries. It erodes vertebrae and discs, which sometimes results in cervical kyphosis and myelopathy. However, to our knowledge, no studies have evaluated improvements to patient-reported outcomes among patients who undergo surgical cervical sagittal realignment after kyphotic cervical spinal tuberculosis has been treated by débridement and reconstruction. QUESTIONS/PURPOSES: (1) Can a spine with kyphotic cervical spinal tuberculosis be returned to normal alignment and fused successfully? (2) Will patient-reported outcomes be improved with this intervention? (3) Are patient-reported outcomes correlated with realignment? METHODS: Forty-six patients with kyphotic cervical spinal tuberculosis were evaluated in this retrospective study...

Lumbar kyphosis and the decreased mobility of the lumbar spine increase the risk of falls and impair both the quality of life and the ability to perform activities of daily living. However, in the elderly Japanese population, little is known about the age-related changes and sex-related differences in muscle strength, including of the upper and lower extremities and back extensors. An adequate kyphotic or lordotic angle has also not been determined. In this study, we evaluated the age-related changes in muscle strength and spinal kyphosis in 252 males and 320 females ≥50 years of age...

There is growing recognition of the kyphotic clivo-axial angle (CXA) as an index of risk of brainstem deformity and craniocervical instability. This review of literature and prospective pilot study is the first to address the potential correlation between correction of the pathological CXA and postoperative clinical outcome. The CXA is a useful sentinel to alert the radiologist and surgeon to the possibility of brainstem deformity or instability. Ten adult subjects with ventral brainstem compression, radiographically manifest as a kyphotic CXA, underwent correction of deformity (normalization of the CXA) prior to fusion and occipito-cervical stabilization...

BACKGROUND: Around 5% of all trauma patients suffer from spinal trauma. Spinal fractures are mainly located in the thoracic and lumbar spine. For multisegmental vertebral fractures categorized as instable, combined dorsal instrumentation and ventral stabilization is recommended. Numerous vertebral body replacement systems are available for ventral stabilization. OBJECTIVES: The aim of the current study was to analyze radiological results following the implantation of a hydraulic expandable vertebral body replacement and the evaluation of patients' outcome three years after implantation...

BACKGROUND: Osteoporotic vertebral compression fracture (OVCF) afflicts most aged people, Except for conservative therapy (CT), percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) are another two the common choices, but current evaluation of their efficacy is not performed. METHODS: All the trial data were originated from electronic database including PubMed, Embase and Cochrane Library. Four indicators with mean difference (MD) or odd ratio (OR) with their 95% credible interval (95% CrI) were analyzed to evaluate the efficacy, including the value of visual analogue scale (VAS), Oswestry disability index (ODI), relieving kyphotic angle (KA) and rate of fracture...
