The 3rd lumbar transverse process syndrome is one of the most common low back pain disorders. The transverse process of the 3rd lumbar vertebra is the center of the whole lumbar spine and is the hub of balance regulation. The transverse process of the lumbar vertebra is the attachment of the anterior layer of lumbar dorsal fascia, and there are intertransverse muscles and intertransverse ligaments in between each transverse process. The transverse process is the starting and ending point of the lumbar square muscle and transverse spinous processes, and the internal oblique muscle and transversus abdominis muscle also originate from this point through the Jian Membrane, which plays an important role in the movement and stabilization of the low back. The transverse process of the 3rd lumbar vertebra is located in the center of the lumbar spine. It is the longest transverse process, and is therefore subjected to the greatest force, and is more susceptible to strain than the other transverse processes. The muscle fascia attached to the transverse process of the 3rd lumbar vertebra is prone to strain injury, causing inflammatory exudation, congestion and swelling of local tissues, followed by proliferation of synovial membrane, fibrous tissue and fibrocartilage. Clinical manifestations: patients often feel lumbar pain or diffuse pain in the lumbar and hip area, and radiate to the back of the thighs above the knee joint, lumbar activities such as bending, rotating the waist when the pain is aggravated, coughing, sneezing and other increases in abdominal pressure has no impact on the examination of the 3rd lumbar transverse process has obvious pressure pain, and can be palpable striated hard nodules. In the early stage, the patient’s waist and buttocks are slightly plump, and in the late stage, there may be mild muscle atrophy. X-ray examination: the 3rd lumbar transverse process can be seen to be hypertrophied. Treatment: injection therapy, massage, can relieve pain, relieve spasm, physical therapy can also relieve tendons and blood, relieve spasm and pain. Can also be closed at the tip of the transverse process and the surrounding tissues, once a week, each time for 2 or 3 times, generally non-surgical treatment can be relieved and cured, only a small number of more intractable pain requires surgical stripping, or excision of the transverse process.
