Asymptomatic Bone Cement Leakage into Inferior Vena Cava during Cement Augmentation of Pedicle Screw for Osteoporotic Vertebral Collapse
نویسندگان
چکیده
Bone cement augmentation of pedicle screw is an important surgical procedure for osteoporotic vertebral collapse, preventing screw loosening, migration or back-out. Bone cement leakage may develop and mostly does not compress the peripheral tissue of the vertebral body including the spinal cord. However, to our best knowledge, bone cement leakage into the inferior vena cava during cement augmentation of pedicle screws for osteoporotic vertebral collapse has been not reported in the literature. We reported an 84-year-old male with asymptomatic cement leakage into inferior vena cava during this procedure and the possible pathophysiological mechanism was also discussed.

Osteoporotic vertebral fracture is becoming increasingly risk factor of the aging population. Percutaneous vertebroplasty is a widely used treatment for the vertebral fracture. However this procedure may carry complication about cement leakage. Here we report a case of a 66-year-old woman who had developed the inferior vena cava and pulmonary embolism after PVP with bone cement leakage. This pa...

BACKGROUND Pedicle screw pullout due to poor bone quality, mainly caused by osteoporosis, is a common problem in spine surgery. Special implants and techniques, especially PMMA augmentation, were developed to improve the fixation of pedicle screws. PMMA injection into a pilot hole or through a screw involves the same risks as vertebroplasty or kyphoplasty, regardless of the technique used. Espe...

Expansive pedicle screws significantly improve fixation strength in osteoporotic spines. However, the previous literature does not adequately address the effects of the number of lengthwise slits and the extent of screw expansion on the strength of the bone/screw interface when expansive screws are used with or without cement augmentation. Herein, four designs for expansive pedicle screws with ...

Osteoporosis causes a decrease in bone mineral density. To overcome the decrease in fixation strength, a variety of techniques and devices have been developed, including cement augmentation of pedicle screws. Polymethyl methacrylate (PMMA), is commonly known as bone cement, and is widely used for implant fixation in various orthopaedic and spine surgery. In general, PMMA augmentation of pedicle...
