Osteoporosis has become a major medical problem as the aged population of the world rapidly grows. Osteoporosis predisposes patients to fracture, progressive spinal deformities, and stenosis, and is subject to be a major concern before performing spine surgery, especially with bone fusions and instrumentation. Osteoporosis has often been considered a contraindication for spinal surgery, while i...

ABSTRACT Postoperative wound infection in an instrumented spine patient is often disastrous. Management includes implant removal leading to spine instability. Negative pressure wound therapy (NPWT) applied to the spine surgical wound is one of the wound care technique with successful results. We report a case of a man who sustained Chance fracture of Lumbar 1 (L1) vertebra treated with long seg...

Study Design Case report. Objective The objective of the article is to illustrate a case of desmoid tumor (DT) formation after posterior instrumentation of the thoracic spine. Methods A 57-year-old woman presented with lower extremity clumsiness, balance, and ambulation difficulty resulting from spinal cord compression due to an upper thoracic atypical vertebral hemangioma. Ten months after und...

Adjacent segment problems after cervical spine instrumentation are widely reported. They can range from asymptomatic adjacent degeneration (ASD) noted on radiographs to symptomatic disease and even instability. While ASD following anterior is well studied, there a paucity of literature posterior instrumentation. We intended identify the risk factors associated with instrumentation, focusing pre...

Gunshot wounds to the spine account for 13% to 17% of all gunshot injuries and occur predominantly in the thoracic region. Minimally invasive spine surgery procedures implementing serial muscle dilation and the use of a tubular retracting system with a working channel minimize soft tissue trauma, facilitate less bony and soft tissue resection, decrease blood loss, minimize scarring and improve ...

A large spectrum of medical devices exists; it aims to correct deformities associated with spinal disorders. The development of a detailed volumetric finite element model of the osteoligamentous spine would serve as a valuable tool to assess, compare, and optimize spinal devices. Thus the purpose of the study was to develop and initiate validation of a detailed osteoligamentous finite element m...

The use of pedicle screw instrumentation in the spine has evolved over the last two decades. The initial use of pedicle screws began in the lumbar spine. As surgeons have become more comfortable with the complex anatomy required for accurate screw placement, the use of pedicle instrumentation has evolved to include their use in the thoracolumbar and thoracic spine. The impetus behind their incr...
