Pathology and TCM Treatment of the Herniated Lumbar Disc East West Healing Center By Dr. Leon Chen www.eastwesthealingcenter.net Definition in Western Medicine Lumbar intervertebral disc injury leads to • partial damage to or tears of the annulus fibrosus • protrusion of the nucleus pulposus • compression of the spinal nerve roots • lower back pain, leg pain (including shooting pain) This is called Lumbar Disc Herniation Syndrome. Definition in Traditional Chinese Medicine (TCM) • Lumbar Disc Herniation Syndrome is called “BiZheng 痹症” in Traditional Chinese Medicine (TCM). • The HuangDiNeiJin in 475-221 B.C.(The Yellow Emperor’s Internal Classic) discussed the syndrome of pain in the low back and leg. Ⅰ Local anatomy The Structure of Vertebral Column The vertebral column in an adult typically consists of 33 vertebrae arranged in five regions: 7 cervical, 12 thoracic, 5 lumbar, and 5 sacral, and 4 coccygeal. The vertebral column is considered to have 26 vertebrae, because 5 vertebrae are fused in adults to form the sacrum and 4 vertebrae are fused to form the coccyx. Curvatures of the Vertebral Column: The vertebral column appears straight from the anterior and posterior position. Laterally, it has three natural curves to balance the body: cervical, thoracic, and lumbar curves. A straight line from head to foot should run through the crossing point of each curvature. Physical Purposes of the Curvatures of the Vertebral Column: 1) To increase the ability of vertebral column to support weight; and balance the body. 2) To decrease the concussion to protect the head. 3) To strengthen the stability of the standing posture. 4) To spread body weight evenly throughout the vertebrae and discs. Measurement of lumbarsacral angle can be found by drawing a line along the sacral base (B) and making a horizontal line (A). Normal values lie between 26-57° with a mean of 41°. lumbarsacral angle L3 The lumbar gravity line: the C line from center of L3 body by drawing a vertical line which pass through the anterior lip of the sacral base (S1), if this C line does not surpass 10 mm that is all normal. 41° A B C Structure of Lumbar Vertebrae: 1) Lumbar vertebrae have massive and flat bodies, because this shape helps to support more body weight. 2) Each vertebrae includes the vertebral body (centrum), vertebral foramen, pedicle, lamina, articular facet, articular process, transverse process and spinous process. 棘突 Spinous process 椎弓板Lamina 上关节突Superior articular process 横突Transverse process 椎孔 Vertebral foramen 椎弓根Pedicle 椎体Centrum 椎弓根 Pedicle 椎体 Centrum 上关节突Superior articular process 横突Transverse process 棘突Spinous process 下关节突 Inferior articular facet Structure of the Intervertebral Disc 1) *Hyaline Cartilage: is the cartilage of the superior and inferior surfaces of the vertebral body. It also forms the top and bottom border of nucleus pulposus. It bears the weight and protects the nucleus pulposus. 2) *Annulus Fibrosus: is a fibrous ring, like a radial tire. It is elastic, embracing and holding the nucleus pulposus, not leting it herniate. 3) *Nucleus Pulposus: is a kind of gelatinous, flexible, semifluid material, located in the center of the annulus fibrosus. Both top and bottom surface are sealed by hyaline cartilage.

Thoracic IV disc, 4.03 mm. Lumbar IV disc, 12.7 mm. Function of Intervertebral Discs : The function of lumbar IV discs is very similar to the intervertebral (IV) discs of the cervical and thoracic vertebra: • To bear the weight of the trunk • To connect to the limbs • To perform normal physical posture and movement. Lumbar IV discs are the most important in the vertebral column. Function of Intervertebral Discs (2) • • • • Uphold the length of the spinal column and body height. Connect with adjacent vertebrae. Bear the weight evenly throughout the vertebral bodies. Act as a cushion or shock-absorber, protecting the spinal cord and brain. (the major purpose. Structure of the Spinal Canal 1) The spinal canal is a passage, formed by successive openings in the articulated vertebrae through which the spinal cord and its membranes (epidural space) pass. Also called vertebral canal. 2) The spinal canal is made up of the vertebral foramen, and ligamentum flavum, and posterior longitudinal ligament. flava ligament posterior longitudinal ligament. Pedicle Superior articular facet Ⅱ Biomechanics of the vertebral column • The vertebral column has inner balance and outer balance which helps the body to move in a balanced way. Normally, both inner and outer balance of the vertebral column keeps the body in perfect balance. 1) Inner balance is formed by discs and facet joints (zygapophysial joints) of vertebrae. 2) Outer balance is formed by dorsal and ventral muscles.

The posterior longitudinal ligament is intact nucleus pulposus Nerve root Posterior longitudinal ligament Spinal cord The posterior longitudinal ligament is torn The posterior longitudinal ligament is torn and the nucleus pulposus is fragmented 受压的神经根 后纵韧带 前纵韧带 Anterior Longitudinal Ligament Posterior longitudinal Ligament Three characteristic pathological evolutionary stages of the nucleus pulposus 1) Pre-herniation. 2) Herniation. 3) Post-herniation. IV Etiology 1) Age and sex: Mostly it affects people in middle age(30-50),males more than females. 2) Location: Mainly occurs at L4-5 and at L5-S1, and secondarily at L3-L4 or L2-L3. 3) Causes: 1)Degeneration of the disc. 2)Injury Disc Ⅴ Diagnosis Symptoms: 1) Low back pain: The pain is mainly located in the lower back area; the back pain results from pressure on the posterior longitudinal ligaments and periphery of the annulus fibrosus. The painful area is deep, and it is usually dull pain or severe, acute pain. 2) Shooting pain in the legs: Lumbar disc herniation often occurs at the L4-5 or L5-S1 level, causing lower back and and hip pain radiating down the thigh on the lateral and posterior sides, down the lateral side of the lower leg, and to the medial and or lateral side of the foot, and toes. Coughing or sneezing can aggravate the pain, causing shooting pain down the lower limbs.

Resulting nerve compression and lack of blood circulation causes malnutrition to the nerves. Clinical symptoms are tingling, numbness and muscle atrophy. 4) Abnormal spinal curvature: • After the lumbar disc herniation, 64% patients have abnormal spinal curvature. The curve of the vertebral column is the body’s way of protecting against low back pain and leg pain. Lateral curvature can relax the nerve root and relieve pain. • Clinically, disc protrusion is generally at the lateral side above the nerve root (45%) A few disc protrusions are at the medial side below the nerve root (7%) Distribution of Disc Herniations and Their Frequency The picture is in the frontal plane 额状面(切掉椎体) Side of spinal cord The disc presses at lateral side above nerve root Spinal cord compression Pedicle section 椎弓根截面 Disc compression of medial side below the nerve root Ligamentum flavum The protrusion is at medial side below nerve root The protrusion is at lateral side above nerve root The curvature protrudes to the healthy side The curvature protrudes to the damaged side How to measure the curve of the vertebral column • To measure the curvature of the spinal column, first find the centers of the two areas of greatest curvature. Draw a straight line throught these centers; from these lines, create a perpendicular (90°) line; cross both perpendicular lines and you will get the measure of the curve. Measure of curvature of vertebral column 30 Ⅵ Special Examination 1) Mobility of Lumbar Vertebral Column: Normal range of motion Flexion 90° Extension 30° Side bend 20°-30° Twist 30° 2) Points painful to pressure If the lumbar disc is herniated, its corresponding vertebra has an obvious tender area. When that area is pressed, pain occurs along the sciatic nerve distribution, shooting down along the lower limb. 3) Abnormal tendon reflexes • If the lumbar disk is herniated, the knee tendon reflex or Achilles tendon reflex can be weak, absent, or excessive. • If the herniation is at L3-L4, the knee tendon reflex can be weak or absent, and foot extension is weak; • If herniation is at L4-L5, the knee tendon reflex and Achilles tendon reflex is normal but toe extension is weak; • If herniation is at L5-S1, the Achilles tendon reflex becomes weak or absent, and foot flexion becomes weak. 4) Lasegue’s test: (Supine) If there is pain in the lumbar area and lateral leg on performing a straight leg raise up to 70° and dorsiflexing the foot, the test is positive. 5) Kernig’s test: (Supine) While bending the hip joint and knee joint to 90° degrees, then extending the knee, if pain is induced, the test is positive. 6) Wasserman’s test: (Prone) The hip joint is overextended. If pain presents at the anterior border of the thigh, the test is positive. 7) Abdominal pressure test: In the supine position, the patient is asked to push the abdomen out while holding breath in. If pain occurs at the lower back and leg, the test is positive. 8) Lindner’s test: The patient’s neck is passively flexed, gradually bringing the chin to the chest. If pain occurs at the lower back and leg, the test is positive, because of meningeal irritation. Lasegue Test Kernig Test Lindner Test Ⅶ Imaging Examination 1) X-ray: • • • • The joint space between vertebrae is uneven. The vertebral foramen is narrowed There is bone spurring. There is spondylolysis--a defect in the pars interarticularis of a vertebra. L3 L4 S1 2) CT Scans and MRI’s provide clear images to examine bone, water, fat, muscle, blood, tendon, ligament, etc. CT and MRI have three views: axial (transverse), sagittal and frontal planes.

Acute Lumbar Injury Acute lumbar injury is caused when: • The waist is flexed • The waist is rotated • Lifting too much weight unbalances the lumbar muscles and creates subluxation of the lumbar facet joints, or lumbar muscle sprain. Diagnosis Points of Acute Lumbar Injury Indications of lumbar injury 1) The pain is mostly in the lower back. Sometimes the pain affects the leg, but there is no shooting pain in sciatic nerve distribution. 2) Pain is aggravated by movement, alleviated by rest. 3) An obvious tender area is easy to find. 4) CT or MRI does not show a disc herniation. 2. Lumbar Spinal Stenosis Lumbar spinal stenosis can be caused by: • Tumors and herniated discs • Degenerative changes (most common cause) that occur with aging, e.g. arthritis • Degenerative effects-- Narrowing of spinal canal causes pressure on the spinal cord or spinal nerve roots. This pressure can lead to many problems that often occur with long periods of walking or standing. • Diagnosis points of Lumbar Spinal Stenosis 1) Lumbar spinal stenosis occurs with aging. Males are affected slightly more than females. 2) Lumbar spinal stenosis occurs mainly in the L3 - S1 region. 3) Lower back pain or leg pain often occurs when walking or standing for long periods. 4) Intermittent claudication. 5) X-ray, CT or MRI can locate the areas of compression of the spinal canal. Lumbar Spinal Stenosis Figure 3. Piriformis Syndrome • The piriformis syndrome is a condition in which the piriformis muscle irritates the sciatic nerve, causing pain in the buttocks and leg, with referred pain, commonly called sciatica, along the course of the sciatic nerve. Diagnosis points of Piriformis Syndrome 1) History of injury to the buttocks. 2) Patients generally complain of pain deep in the buttocks, which is made worse by sitting, climbing stairs, or performing squats. 3) No low back pain or spinal column curvature. 4) Special examination will be positive. 5) CT or MRI does not show a herniated disc. Piriformis Figure 4. Sciatic Neuritis Sciatic pain mainly is caused by viral infection, which damages the sciatic nerve. This is also called sciatic neuritis, and isn’t commonly seen clinically. 5. Spinal Tumors • The cause of pain may be a spinal tumor — a cancerous or noncancerous growth that develops within or near the spinal cord or in the bones of the spine. • In most areas of the body, noncancerous tumors aren't particularly worrisome. But in the vertebrae both kinds of tumors are of concern. 6. Sacroiliac Joint Injury • The sacroiliac joint (SI joint) is a firm, small joint that lies at the junction of the spine and the pelvis. Most often when we think of joints, we think of knees, hips, and shoulders--joints that are made to undergo motion. The sacroiliac joint does not move much, but it is critical to transferring the load of your upper body to your lower body. Diagnosis Points of Sacroiliac Joint Injury 1) Indication of lumbar injury 2) Pregnancy or delivery may injure the SI joint 3) Pain on one side lower back, without leg pain. 4) Faber’s test (“4” character test ) is positive. 5) Studies (X-Rays, MRIs, CAT Scans, Bone Scans) are often normal 7. The Third Lumbar Transverse Process Syndrome • The pain spot is at the third lumbar transverse process area, and also affects the buttocks and lateral thigh. That is caused by the friction between transverse process and muscles, which causes inflammation. The third lumbar transverse process may be normal in length, or too long. Diagnosis points of the third lumbar transverse process syndrome 1) The pain can be on one or both sides of the third lumbar region, and may radiate to the posteriolateral part of the thigh in severe cases. 2) The patient is unable to sit and stand for long, with pain aggravated on sitting or standing and alleviated after rest. 3) A longer or normal transverse process of the third lumbar vertebra is shown in the X-ray or MRI film. 8. Pelvic inflammatory disease Pelvic inflammatory disease (PID) is a general term that refers to infection of the uterus, fallopian tubes and bladder. The inflammation can irritate tissues and muscle, causing lower back pain. Diagnosis points of PID 1) Lower back or pelvic pain, with no history of injury. 2) Abnormal vaginal discharge. 3) Antibacterial treatment reduces the pain. 4) Laboratory examination and ultrasoud or CT exam reveals the problem. 9. Entrapment syndrome of superior cluneal nerve • The medial branch of the superior cluneal nerve passes over the iliac crest through a tunnel down to the buttocks. In that particular area the superior cluneal nerves are compressed easily when injured. They innervate the skin of the upper part of the buttocks and lateral thigh. Diagnosis points of entrapment syndrome of superior cluneal nerve 1) Indication of injury to lumbosacral area. 2) The pain occurs in the specific area of the nerve and radiates to the lateral thigh. 3) Bending the waist and walking causes pain. Also, changing posture from sitting to standing is difficult. The dorsal cutaneous rami nerves Trapezius Superior cluneal nerve Latissimus dorsi Gluteus medius Gluteus maximus 10. Entrapment syndrome of the lateral femoral cutaneous nerve • It is a syndrome of pain in the lateral and anterolateral thigh. • The lateral femoral cutaneous nerve passes through and underneath the lateral aspect of the inguinal ligament, and finally travels to innervate the lateral thigh. It divides into anterior and posterior branches and supplies skin from the greater trochanter to the mid thigh. • If the nerve is pressed when injured, it causes burning pain and numbness of the greater trochanter and the mid thigh. Diagnosis points of entrapment syndrome of the lateral femoral cutaneous nerve 1) 2) 3) 4) 5) 6) This syndrome is most commonly seen in individuals aged 20-60 years, but it can occur in people of all ages. Sports injuries such as trauma or muscle tears of the lower abdominal muscles may also result in injury to the nerve. It may also occur during pregnancy due to the rapidly expanding abdomen in the third trimester. It may also be caused by injury from surgical procedures. There is pain on deep palpation just below the anterior superior iliac spine and from hip extension. The pain is at the lateral thigh or anterolateral thigh and down to the knee and also sometimes in the inguinal region. Lateral femoral cutaneous N Femoral N Lateral femoral cutaneous N Femoral N 11. Greater trochanteric bursitis • Greater trochanteric bursitis is characterized by painful inflammation of the bursa located just superficial to the greater trochanter of the femur. • Patients typically complain of lateral hip pain, although the hip joint itself is not involved. Pain may radiate down the lateral aspect of the thigh. Diagnosis points of greater trochanter bursitis 1) 2) 3) 4) 5) 6) With acute trauma, patients may recall specific details of the impact. The classic symptom is pain at the greater trochanteric region at the lateral hip. Pain may radiate down the lateral aspect of the ipsilateral thigh. Pain usually does not radiate all the way into the foot. Typically, symptoms worsen when the patient is lying on the affected bursa (eg, lying in the lateral decubitus position). Pain may awaken the patient at night. Palpation also may reproduce pain that radiates down the lateral thigh, but it does not go below the knee. Greater trochanter 12. Entrapment Syndrome of Common Peroneal Nerve • The common peroneal nerve courses around the fibular neck and passes through the fibroosseous opening in the superficial head of the peroneus longus muscle. This opening can be quite tough and result in the nerve passing through it at an acute angle. • The common peroneal nerve gives off 2 branches: the superficial peroneal nerve (the lateral cutaneous nerve of the calf ) and deep peroneal nerve (the sural communicating branch nerve ) • Diagnosis Points of Entrapment Syndrome of Common Peroneal Nerve 1) Peroneal nerve injuries are most common peripheral nerve injuries in the lower limb after multiple traumatic injuries. 2) Chronic compression injury is the cause. 3) The loss of sensation in the cutaneous distribution of the superficial and deep peroneal nerves may be noted, but ankle dorsiflexion weakness is often of most concern to the patients.
