Halo-gravity traction (HGT) is a type of traction device utilized to treat spinal deformities such as scoliosis, [1] [2] congenital spine deformities, cervical instability, basilar invagination, and kyphosis. [3] It is used prior to surgical treatment to reduce the difficulty of the following surgery and the need for a more dangerous surgery.
Regain normal length and alignment of involved bone; Lessen or eliminate muscle spasms; Relieve pressure on nerves, especially spinal nerves; Prevent or reduce skeletal deformities or muscle contractures; To provide a fusiform tamponade around a bleeding vessel; In most cases traction is only one part of the treatment plan of a patient needing ...
After viewing the track site and "once factors such as topography, wind direction, infrastructure and soil quality are known" the design work can begin. [1] Tilke focuses on "conceiving dramatic architecture that reflects the host country, like Sepang's lotus-leaf grandstands in Malaysia", while also aiming for spectator comfort and clear ...
The paper "Mobility-Maintaining Arthroplasty of the Lumbar Spine with the Second-Generation TOPS System" by Werner Lack, Hans Paul Kutschera, and Josef Krugluge found that the TOPS facet replacement can relieve leg and back pain while maintaining nearly normal range-of-motion for four years without causing adjacent segment disease. The study ...
For spinal fusion surgery on AIS cases, with instrumentation attached using pedicle screws, complication rates were reported in 2011 as transient neurological injuries between 0% to 1.5%, a pedicle fracture rate of 0.24%, screw malposition assessed by radiography at 1.5%, 6% when assessed by CT scans though these patients were asymptomatic not ...
It represents <1% of all cervical spine injuries. [1] Several subtypes of atlanto-occipital dislocation are known. One suggested categorization scheme includes anterior, vertical and posterior of the head relative to the spine. Other variants with lateral or rotatory displacement have been described, as well as mixed types.
The "Type" column refers to the type of circuit: "street" is a circuit held on closed city streets, "road" refers to a mixture of public roads and a permanent track, and "race" is a permanent facility. The "Last length used" shows the track length for the configuration that was used last time the Formula One race was held on a given track.
It is not unusual for patients to walk in for treatment and have such a fracture discovered on X-rays. Only if the force of the injury is severe enough that the vertebral body of C2 is severely subluxed from C3 does the spinal cord become crushed, usually between the vertebral body of C3 and the posterior elements of C1 and C2.
