The third lumbar transverse process is the longest of the five lumbar transverse processes and is the central point of lumbar activity and stress concentration. When the lumbar region is subjected to external force or improper posture, the muscles, ligaments and fascia attached to the third lumbar transverse process can cause injury, and after the injury there is local exudative inflammation, then the third lumbar transverse process syndrome will be formed. The pain is usually predominantly in the lumbar region, with significant pressure points and even striated changes in the lumbar region, and in severe cases, it may radiate to the buttocks and the back of the thighs. The acute stage can be treated with oral anti-inflammatory and pain-relieving drugs and bed rest; the chronic stage can be treated with massage and acupuncture; if the effect of these treatments is not satisfactory, local closure or local small acupuncture can also be used; for a small number of patients who cannot be cured after repeated treatments, surgery can be considered to cut off the lumbar truncal process.
