Brief introduction of lumbar traction

Lumbar traction is the use of traction and reverse traction on the lumbar spine, through reverse traction to achieve the purpose of treating lumbar disc herniation. Lumbar traction can enlarge lumbar intervertebral space, mainly lumbar intervertebral space 3, 4, 5 and sacrum 1. According to the research, the lumbar intervertebral space after traction is 65438±0.5 ~ 2.5mm wider than before traction. The widening of intervertebral space can make it become negative pressure, and the tension of longitudinal ligament after traction is beneficial to accommodate the protruding nucleus pulposus or change its relationship with nerve roots. With the enlargement of intervertebral space and the opening of articular process, the intervertebral foramen returns to its normal shape, thus relieving the compression on nerve roots. Traction can also make the lumbar spine get enough rest, reduce the stimulation of exercise, be beneficial to the absorption and regression of tissue congestion and edema, and also relieve muscle spasm and intervertebral pressure.
