Reduction bed for thoracolumbar vertebral compression fracture

Technical Field

The utility model relates to a bed in the medical apparatus research field, in particular to a thoracolumbar vertebrae compression fracture reduction bed.

Background

Compression fracture of thoracolumbar vertebrae is one of the spinal injuries commonly suffered by the old. Such fractures vary most commonly with wedge-like compression, often resulting in pain and kyphosis in elderly patients. The existing operation internal fixation is often not firm, and the fixed segment is longer, and the wound is big, and the risk is high, appears internal fixation defects such as not hard up, fracture easily. The traditional treatment includes bed rest, wearing of waist support and pain relief, but the effect is not good, and it is difficult to recover the height of diseased vertebra and correct the kyphosis.

In order to restore the physiological curvature of the normal spine of a patient as much as possible and reduce kyphotic deformity, the patient can be braked on a hard board bed through lying on the back in clinical treatment, the injured back is padded with a soft pad to enable the back to be in a backward stretching state, but the traditional back bolster restoration method mostly adopts towels, cotton pads, sand bags and the like, but the thickness of the traditional back bolster restoration method is difficult to adjust and the operation is inconvenient; and the patient has poor comfort by locally propping against the injured vertebra. The observation in clinical treatment shows that after the patient takes the prone position, the patient is padded up at the position close to the armpit of the upper chest and the anterior superior iliac spine of the pelvis, so that the spine of the chest and waist section is suspended, and the fracture reduction has better treatment effect by means of the weight of the patient. However, the patient is inconvenient to operate by only using the soft cushion due to the uneven body size, weight and the like of the patient, and a fracture reduction bed suitable for prone posture is not available at present.
