BACKGROUND: In the light of the increasingly aging population and the widespread understanding of the sagittal profile of symptomatic patients with adult spinal deformity (ASD), pervasive utilization of osteotomies on the vertebral column should be expected. These surgeries are accompanied with relatively high complication rates. However, there is no uniform definition or classification in terms of grading the severity or chronological incidence of complications after ASD surgery. OBJECTIVES: The aim of this work is to give an overview of the different classifications described in the literature hitherto and to propose a standardized, clinically utile classification of complications after ASD surgery...

Vertebral fractures commonly occur at the thoracolumbar junction. These fractures can be treated with mild residual deformity in many cases, but are reportedly associated with increased risk of secondary vertebral fractures. In the present study, a three-dimensional (3D) whole spine model was constructed using the finite element method to explore the mechanism of development of compression fractures. The 3D model of the whole spine, from the cervical spine to the pelvis, was constructed from computed tomography (CT) images of an adult male...

PURPOSE: To predict the sagittal spinal parameters as measured in a 3D model of the spine using the 2D radiographic measurements. METHODS: Bi-planar low-dose stereoradiography images of 73 right thoracic AIS patients were processed to generate 3D models of the spine and pelvis. T1-T12 kyphosis, L1-S1 lordosis, and pelvic rotation were calculated using these 3D models. With the same X-rays, T1-T12 kyphosis, L1-S1 lordosis, thoracic and lumbar frontal curves, and pelvic rotation (calculated from the frontal and sagittal distances between the femoral heads) were manually measured on the X-rays by two independent observers...

BACKGROUND: Pharmacological prophylaxis for venous thromboembolism (VTE) in the neurosurgical population is still a matter of debate, as the risk-to-benefit ratio is not well defined. OBJECTIVE: To further evaluate the risk-to-benefit ratio of VTE prophylaxis (VTEP) for all neurosurgical procedures. METHODS: A prospective evaluation was performed after the initiation of a VTEP protocol for 11 436 patients undergoing neurosurgical procedures over 24 mo...

BACKGROUND: Osteogenesis imperfecta (OI) is most often caused by mutations in type I collagen genes. Respiratory complications have been largely attributed to spine and ribcage deformities. We hypothesized that direct involvement of the pulmonary parenchyma and/or diaphragm by the disease may occur. METHODS: In Col1a1Jrt/+ mice, a model of severe dominant OI, mean linear intercept length (Lm) was used to assess distal airspace size. Cross-sectional area (CSA) and myosin heavy chain (MyHC) phenotype of diaphragm muscle fibers, as well as contractile properties, were determined...

BACKGROUND: Adolescent idiopathic scoliosis (AIS) is the most common structural deformity of the spine. Genetics constitute largely to AIS, and the rs11190870 polymorphism has the potential for use in public health and clinical settings as a predictor of AIS risk. The aim of the present meta-analysis was to provide exhaustive evidence to evaluate the association of rs11190870 with the susceptibility and severity of adolescent idiopathic scoliosis (AIS) in multiple ethnic groups and different genders...

BACKGROUND CONTEXT: Pelvic Tilt (PT) is used as an indicator of pelvic version with increased values indicating retroversion and disability. The concept of using PT solely as an absolute numerical value can be misleading, especially for the patients with Pelvic Incidence (PI) values near the upper and lower normal limits. Relative Pelvic Version (RPV) is a PI-based individualized measure of the pelvic version. RPV indicates the individualized spatial orientation of the pelvis relative to the ideal sacral slope as defined by the magnitude of PI...

The treatment of sports injuries in the skeletally immature has a unique set of complications. Growth deformity may occur after anterior cruciate ligament reconstruction; therefore, skeletal age is used to help guide the choice between physeal sparing and transphyseal techniques. Arthrofibrosis after tibial spine fracture fixation can be reduced by initiating immediate range of motion, and should be treated early and cautiously to avoid iatrogenic fracture. Nonunions of medial epicondyle elbow fractures are more common with nonoperative treatment, but seldom lead to clinical problems outside of certain athletes...

RATIONALE: Skipped multifocal extensive spinal tuberculosis (TB) involving the whole spine is very rare. So far, only 3 cases have been reported. PATIENT CONCERNS: We report a rare case of skipped multifocal extensive TB involving the whole spine of a 33-year-old Chinese male. The patient had been asymptomatic until his symptom was significantly aggravated, which caused him to have difficulty in walking and sleeping. The whole spinal computed tomography (CT) scan showed multifocal worm-eaten and osteolytic bony destruction spread over noncontiguous multilevel vertebral involvement in cervical, thoracic, lumbar, and sacral...

Various shoulder bone deformities have been identified in the pediatric age group, with the most common being undescended scapula. Sprengel's deformity is dysplasia and malposition of the scapula, especially in the supraspinatus portion, mainly due to abnormal descent in the embryonic period. The clavicle is shorter and has a different contour. In some patients cervical spine deformities are also noted. This is a case of 3 years old girl presented to the clinic with difficulty in abducting right shoulder and sleeping with an internal rotation of the right arm...
