Cord concussion usually complicates cord contusion. This confuses everybody except the mentor's disciples. EXTENSION FROM FLEXION This allows the sacrum to move inferior, anterior, and medial, coupled with the anteroinferior angulation of the sacral base. ETIOLOGIC PICTURE These signs suggest instability that is rarely confirmed by physical examination alone. 4. Curvatures arising from locomotion dysfunctions (eg, pelvic subluxation-fixations, contractures, paralysis) are called curvatures of disturbed motion or dynamic curvatures. A listing of common problem areas in the lumbar area is shown in Table 12.7. While episodes of low back pain may be self-limiting within 4–6 weeks, they tend to recur and each successive attack tends to become progressively more severe. In this condition, the movements of the spine are diminished or may perhaps eventually be lost. 7. Degenerative joint disease, exostoses, inflammatory or fibrotic residues, narrowing from disc degeneration, and tumors --all must be considered. This is especially true of the rectus abdominis. Overall curvatures of the spine should be noted and evaluated as normal, lordotic, kyphotic, or scoliotic. Common Problems in Adulthood. The primary precipitating factors usually involved are a sudden stress at an unguarded moment or lifting with inadequate mechanical advantage. If pelvic rotation fails to occur, the first suspicions should be sciatic irritation, hip restriction, or tight hamstrings. When the gluteus medius shortens to abduct the hip when the patient is laterally recumbent, the contraction tends to separate the ilium from sacrum. All of Dr. Schafer's books are now available on CDs, with all proceeds being donated The Sacroiliac Ligaments. In the relaxed lateral recumbent position, the lumbar region glides laterally (with some coupled rotation) toward the floor --especially if the mattress is soft. PLUMB LINE ANALYSIS All trunk flexors and extensors can produce lateral flexion when acting unilaterally. Kemp's Test. This will normally be about a half inch if the dynamics are normal, and the sacral tissues will be felt to tighten. Several authorities state that sacroiliac pain will always be on the side of hypermobility, while others of equal credentials place the pain on the side of fixation. Subluxations may occur at other points in curves and rotations, particularly at the beginning point of a primary defect in balance such as in the lower lumbar and upper cervical sections. As the patient curves his trunk laterally, the lumbar spine should curve smoothly, the sacrum will normally tilt towards the side of the concavity, but the PSISs should remain relatively level even though there is some bilaterally reciprocal iliac rotation. Because of the lax capsules, a minor sprain can produce a severe synovitis at the posterior joints. It may not occur until several minutes or hours after an injurious event has taken place. Whatever technique is used, the purpose of stretching is to loosen all soft tissues that are taut and restricting joint motion. In studying spinal distortion patterns, it is well to keep in mind Logan's rule: "The body of the lowest freely movable vertebra always rotates towards the lowest side of the sacrum or the foundation upon which it rests." Thus, determination of the integrity of or subluxation of the facets in any given motion unit is important in assessing that unit's status. These forces are especially increased at the L4 and L5 discs because of their angle from the horizontal plane. However, if the sacroiliac joint is locked, normal torsion is inhibited and axial torsion of the cord and nerve roots occurs. Spondylitis The midthoracic spine is always scoliotic toward the side that the vertebral margin of the scapula is more prominent and flaring. The supine patient is asked to place both hands behind his head and forcibly flex his head toward his chest. Standing Test for Inferior Joint Motion. The mechanism of injury is usually intrinsic rather than extrinsic. An increase or decrease in the sacral angle determines the direction of the lumbar spine.       TRANSVERSE PROCESS FRACTURES When lumbago and sciatica are coexistent, Demianoff's sign is negative on the affected side but positive on the opposite side unless the pelvis is fixed. The patient lies supine with legs extended. However, Wyke and others report that they are. Although skeletal muscle tissue lacks an intrinsic lymph supply, a muscle's connective tissue sheath and tendons are richly endowed with lymphatic vessels. The vast majority of trunk/torso rotation occurs in the thoracic spine (see thoracic rotation ). In treating the fragile elderly, the cardinal concerns in both diagnosis and therapy are arteriosclerosis, demineralization, and diminished collagen. If there is excessive joint laxity, subluxation with or without sprain or strain may occur. A scoliosis will sometimes exhibit a lordosis and a somewhat anterior curvature of the spine between the scapulae. See Table 12.18. Ipsilateral shortening of the external oblique with contralateral internal oblique shortening produces a scoliosis. It is for this reason that the direct cause of a sacroiliac sprain-subluxation may not be within the joint itself and recurrence can only be avoided if the coupled joints, ligaments, and muscles are kept elastic. Repeated episodes of minor trauma and tissue changes predispose progressive degenerative arthritis. It is not unusual to find that one side is unrestricted and the other side is blocked. Concussion of the Spinal Cord. Overstress disrupts muscle fibers, and this produces bleeding, swelling, and exudate organization leading to further adhesions. A large percentage of cases show a degree of associated spondylolisthesis, usually with normal neurologic signs. Extension is controlled by stretching of the anterior longitudinal ligament and rectus abdominis, relaxation of the posterior ligaments, and contraction of the spinal extensor muscles. This process of disc and associated tissue destruction places excess weight on the apophyseal facets. During the first stage of flexion, the normal lumbar lordosis gradually flattens and then gradually develops a smooth curved kyphosis. The Sacroiliac Ligaments. If the L4 is involved, pain is usually referred anteriorly to the groin or upper thigh. The Quadratus Lumborum. In common pelvic mechanical pathologies on the side of involvement, there is an observable slanting and anteriority of the pelvis in the forward bending position. Although the transverse processes of the lumbar spine are quite sturdy, ultiple fractures are seen after severe accidents. The anterior or posterior sliding of one vertebral body on another (spondylolisthesis or retrolisthesis) usually results from either traumatic pars defects or degenerative disease of the facets. Unfortunately, most people use a majority of specific and specialized movements instead of maintaining a healthy general mobility. However, if the lumbar spine is relatively flat or if the lateral bending is performed in the sitting position, the amount of associated rotation is minimal. This helps to further explain why fixation inhibiting rotation during flexion invites IVD protrusion. If chronic sciatic neuralgia is on the high iliac crest side, degenerative disc weakening with posterolateral protrusion should be suspected. Mennell's Test. Howe points out that after falls or trauma to the back, particularly where the blow is applied to the bottom of the pelvis with the force traveling up the spinal column, compression fractures of vertebral bodies frequently result. (1) the IVFs are narrowed, (3) an anterior sacral base with a "sway back"; or TRUNK LATERAL FLEXION See Chapter 2, Vertebral Subluxation Syndromes. Hip restriction forces excessive motion upon the lumbar spine and sacrum. It is the effect of mechanical deformation of soft tissues of the motion unit as the result of acute overactivity or prolonged postural stress that leads to pain. (3) a combination of stretch reflex and relaxation reactions if fibers have been stretched to a pathologic length. On a lateral roentgenograph, the involved articular space exhibits an abnormal V-shaped appearance and the disc space will appear increased at the anterior and decreased at the posterior. Table 12.7. The lower back and pelvis are the most common sites for avulsion-type injuries. When the upper third of the anterior surface of the thigh is mildly stimulated by stroking, the reflex consists of extension of the knee with plantar flexion of the first three toes in which the foot may also participate by full plantar flexion. Stress upon the joint should increase pain such as in lateral compression or torsion of the iliac crests. The supine patient is asked to place both hands behind his head and forcibly flex his head toward his chest. DISTORTION SIGNS When the spine is in good alignment, facet articulation offers minimal friction. However, an entrapped fragment or protrusion would not be benefited and may be aggravated. As the process continues, the involved disc becomes dehydrated and thinning increases. Fibers on the side of the concavity shorten, and fibers on the side of the convexity lengthen. The Adams maneuver is possibly the best to detect unusual vertebral rotation and ascertain the integrity of lumbosacropelvic rhythm. Regardless of the initial cause, the disc space narrows and the posterior facets compress and "telescope" as the superior segment tends to slide posteriorly upon the inferior segment of the motion unit, which tears or at least stretches the posterior aspect of the capsules. Lower figure: lower trunk. The distance between the contacts are noted. The direct mechanism is failure of the muscles acting on the sacral apex to elongate. This causes extension to be further restricted to avoid stress upon the posterior extrusion of the anulus. Its causes may be direct or referred and be the result of dysfunction or disease, either focal or general in nature. Facet Angle Variations Bilateral or unilateral fixation of a posterior motion unit, causing restricted forward flexion. If the sacroiliac joint is inflamed from trauma or disease, abduction of the thigh against resistance is acutely painful. In most cases, restricted mobility will be found in thigh flexion or hyperextension. With the patient supine, the examiner extends the patient's thigh on the affected side and rotates the hip joint internally by rotating the leg at the knee. However, generalized bilateral ligamentous shortening in itself is not necessarily a cause of clinical concern even if a state of mobility is considered ideal. Similar to musculature, determining a ligament’s role in restricting rotation can best be seen by looking at how the ligament (partially) “wraps” around the body part in the transverse plane. Quite frequently, psychologic stress superimposed on a biomechanical fault precipitates episodes of backache. See Table 12.13. During lateral bending in the erect position, considerable rotation accompanies the abduction motion if there is a significant degree of lordosis. The incidence of low back disorders of a protracted and recurring nature is much higher in those patients whose spines show evidence of development defects and anomalies. Sciatica that is aggravated in the standing but not the supine position suggests a nerve root involvement. The center of gravity is forward of the ischii, the lumbar lordosis is but slightly flattened, and about 25% of body weight is transmitted to the floor through the lower extremities. Concussion of the Spinal Cord. The amphiarthrodial joint between the vertebral bodies frequently shows narrowing, spurring, and associated osteoarthritic changes. This quadrate muscle, which acts as one large muscle on each side of loin, connects the iliac crest and thoracolumbar fascia to the 12th rib and transverse processes of the lumbar vertebrae. Rotational malpositions of the lower lumbar vertebrae are frequently found and invariably associated with changes in the related disc and posterior joints. The patient should be instructed to stand relaxed, with the heels together and the hands hanging normally at the sides. Sciatic neuralgia or neuritis is characterized by pain of variable intensity to a maximum that is almost unbearable. This relief, a positive Berry's sign, comes from hamstring relaxation. The Derangement Syndrome. This causes one or several of these ligaments to shorten and tighten, which in turn causes the involved ligament to serve as a new, but abnormal, center of rotation that may restrict mobility in one or several directions. This latter point is an excellent method of gathering accurate clues of biomechanical faults. If the upper cervical segments indicate vertebral body rotation to the right, the head and neck actively and passively rotate to the right with greater ease than to the left. Shortening of the lumbar extensors has the opposite effect as that of hamstring shortening. Widening of the anterior disc on extension or of the posterior disc on flexion does not occur until movement nears its full range of motion. Illi's studies have shown that most scolioses classified by allopaths as primary lumbar scolioses have their origin in sacroiliac dysfunction, but any disturbance in movement may give rise to such a curvature. A positive sign may be elicited in a sacroiliac, hip, or lower lumbar nerve root lesion. The movements of the spine are flexion, extension, lateral flexion (sidebending) and rotation. The Erector Spinae. Careful differentiation is important because the intrinsic strength of the posterior ligaments makes severe sprain unlikely and because the joint is the common site of diffuse referred pain and tenderness. Sciatica is frequently absent during the early stage, but it may be elicited by a strong Valsalva maneuver. Acute phenomena are usually the result of friction, severe or repeated trauma, and encroachment from degenerative thickening or exostosis, rather than of neurologic origin. This leads to tunnel vision because many disorders, both spinal and extraspinal, may simulate disc disease. The typical clinical picture exhibits severe antalgic spasm, thoracolumbar hyperkyphosis, muscular tenderness, no bony tenderness, positive Lasegue's sign, tight hamstrings, and negative roentgenographs. An anatomic or functional short leg, causing the lumbar spine to follow the tipped base of the sacrum. This point should be recorded. Abnormalities in these mechanisms will quickly point out and help differentiate sites of lumbar, sacral, or hip restrictions or instability. Localized point tenderness and the standard kinesiologic and orthopedic tests are helpful in differentiating mimicking musculoskeletal disorders. Normally, no pain should be felt on this maneuver. The pull is made on the ilium through the Y ligament and the muscles attached to the anterior iliac spines. Body weight in the erect sitting posture should be supported upon the ischial tuberosities and the adjacent soft tissues. The articulations of the lower back are located fairly central to the kinematic chain extending from the cranium to the feet. Asymmetrical facets or facets facing in an unusual plane. SACROILIAC SPRAINS If involved in either local or reflex hypertonicity, the posterior lumbar articulations on the side of fixation are forced open in an abnormal arc. Regardless, it shows that sacroiliac dysfunction is probably present. The L5–S1 and sacroiliac joints, the pelvis, and its contents deserve careful scrutiny. Roentgenographic evaluation is made by drawing a line through the superior border of the sacral base and through the inferior border of L5. The precipitating cause is often through overbending, a steady lift, or a sudden release --all of which primarily involve the musculature. This has been estimated as a 15:1 ratio; thus, holding a 20-lb weight in front with the arms held horizontal must be counteracted by at least a 300-lb contraction of the spinal extensors to maintain equilibrium. This eventually leads to pain. To test A-P mion during extension, the same contacts are taken and the patient is asked to arch the back posteriorly. When this condition exists, there is generally a flattening of the anterior curvature of the lumbar vertebrae. An increase or decrease in the sacral angle determines the direction of the lumbar spine. STANDING LATERAL BENDING The greater the degree of sacroiliac fixation, the greater degree of stress placed upon the lumbosacral and hip joints. Hamstring extensibility can be tested passively and dynamically with manual muscle extensibility examination. Retrolisthesis is often the result of some infectious or degenerative disc process according to Finneson, but Gehweiler feels that such changes may be absent. The lumbar spine extends 20 to 30 degrees C. Both of the answers are correct. In this position, body weight (plus loading) pulls the sacrum anterior, while taut pelvic extensors pull the ilia posterior. However, we should also avoid the tendency to generalize that all such symptoms and signs are referred. Relief usually comes spontaneously after rest, but idiopathic episodes may occur and then disappear with further maturation. The increase in muscle bulk following prolonged exertion is caused by two factors: (1) the opening of capillaries during activity that are closed during rest, and If a posterior disc protrusion or an irritated nerve root is involved, the patient will invariably assume an antalgic position. In distinct lordosis, however, the facets are relatively locked and lateral flexion is so restricted that the vertebrae must severely rotate (far more than the normal coupling motion) to allow lateral bending. Extension. Muscle weakness, sensory deficits, and reduced circulation of the lower extremities that differ bilaterally are usually associated. There is a high incidence of trauma and strenuous physical activity in the history of spondylolysis such as fatigue fractures from falling on the buttocks. Extension occurs from above downward. To measure flexion, the standing patient flexes forward and attempts to touch the floor with his fingertips. In all cases, the patient should be alerted that jugular pressure may result in vertigo. (3) induction of spinal curvatures and/or contributions to the chronicity of existing curvatures, and When the defect appears as a collar on the dog, a spondylolysis is present. For instance, the pubic articulation may tighten and effectively stop A-P rotation of the ilia. The common indirect x-ray signs of disc degeneration are disc space narrow- ing, retrolisthesis, posterior subluxation, traction spurs, and facet degeneration. Anterior disc collapse or a fixed facet separation would be a more logical cause if a segmental kyphosis is present. The reason they are often missed is that the pain is usually referred to the lumbosacral area, and there may be no spasm or even tenderness in the fracture area. There is usually a C scoliosis away from the side of pain, splinting, and a flattening of the lumbar spine. DIFFERENTIAL DIAGNOSIS TIPS These adhesions respond well to manipulative therapy, but they will recur unless the joint is exercised a few minutes a day to its maximum range of motion. These afferent fibers have extensions into the dorsal horns of the cord at the same level and from three to four segments above and below. A complete history is vital to offer the most accurate diagnosis and the best management and counsel. Gaenslen's Test. However, it would appear that any site of irritation in the lower back and pelvis would be aggravated by such a maneuver. To test A-P mion during extension, the same contacts are taken and the patient is asked to arch the back posteriorly. If this maneuver is markedly limited by pain, the test is positive and suggests sciatica from a disc lesion, lumbosacral or sacroiliac lesion, subluxation syndrome, tight hamstring, spondylolisthetic adhesion, IVF occlusion, or a similar disorder. Action: Primary spine extensor, whilst aiding in the control of spine flexion. Neurologic symptoms develop rapidly, but the lower the injury, the fewer roots will be involved. BASIC INVESTIGATIVE APPROACH ETIOLOGIC PICTURE. D. None of the answers is correct. These failures are often complex, accumulative, and subtly hidden by the body's marvelous adaptive mechanisms --a diagnostic challenge when pain is solely referred. Many authorities state that the sacrum and pelvis can be considered a biomechanical unit where rocking of the pelvis is accompanied solely by a change in the sacral angle. Automatic foot plate and seat adjustments (electronic version) Range of Motion adjustment to accommodate various users If the upper cervical segments indicate vertebral body rotation to the right, the head and neck actively and passively rotate to the right with greater ease than to the left. Cailliet feels that 75% of all postural low back pain can be attributed to hyperlordosis, while Barge contributes most low back pain to lumbar kyphosis. Lateral positions of the spinous processes and anterior or posterior positions of the transverse processes together with an elevation of the angles of the ribs would indicate a rotation of vertebrae. Several authorities state that sacroiliac pain will always be on the side of hypermobility, while others of equal credentials place the pain on the side of fixation. Gluteus max., hamstrings, gastrocnemius, soleus, Numbness at cleft between 1st and 2nd toe, dorsal foot, Numbness inferoposterior to lateral maleolus, heel, dorsal calf, lateral foot. Any muscle with vertical or oblique fibers that connects the thorax with the pelvis assists in flexion of the trunk. Howe points out that after falls or trauma to the back, particularly where the blow is applied to the bottom of the pelvis with the force traveling up the spinal column, compression fractures of vertebral bodies frequently result. Because of the lax capsules, a minor sprain can produce a severe synovitis at the posterior joints. (3) there is increased tenderness over the origin of the sartorius muscle. Leg raising from the supine position is a two-phase combination between strong abdominals and strong hip flexors. If fixation is present, these iliac and ischial motions will not be felt. If there is a right structural scoliotic deviation of the lumbar area, the patient sitting, with pelvis fixed, will find it easier to rotate the torso to the right than to the left. Weak recti are portrayed by a loss in trunk flexion and posterior pelvic rotation strength. This test may be helpful in differentiating the various etiologies of sciatic pain and is particularly designed to differentiate between pain from pressure on the nerve or its roots and pain due to other mechanisms in the lower back. Excessive hypertonicity of a muscle, confirmed by palpatory tone and soreness, will tend to subluxate its site of osseous attachment. TRUNK ROTATION 46). The sacroiliac tissues should be felt to relax. An imaginary line passed through the crease of the buttocks should demonstrate its lower aspect equally between the feet and its upper aspect over the C7 spinous process and the occipital protuberance. DISTORTION SIGNS The Prone Position This act stretches the anterior abdominal and iliopsoas muscles and increases intrathecal pressure. BASIC INVESTIGATIVE APPROACH Oblique Shortening. Many of the abnormal orientations found in the lower spine are because the lumbar facet joints are not determined until the secondary curves are developed in the erect position. Kernig's Neck Test. Sacroiliac fixation to any degree inhibits the compensatory torsion capacity of spinal segments. There is a lessening or lack of the patellar tendon reflex in sciatica (Babinski's sciatica sign). Motor to iliacus, pectineus, sartorius, quadriceps femoris. At times, the cause is readily apparent. PERTINENT ASSOCIATED COMPLAINTS AND FINDINGS The L5–S1 trigger is usually within the multifidi. When the healthy spine extends from flexion, the lumbar spine does not create its lordosis until near the upright position when body weight becomes centered on the discs. Lateral bending is then conducted, bilaterally. Or, conversely, the PSIS will move posterior and inferior. However, in no way should it preclude the use of necessary instrumentation, laboratory procedures, or roentgenography. Straightening up or lifting from a stooped position can cause a traumatic unilateral or bilateral displacement of the sacrum within the ilia, thus spraining the sacroiliac and iliolumbar ligaments. Intrathecal pressure can be ruled out in the typical adult if the patient can hold this position for 20 seconds without pain. The ligamentum flavum rarely thickens in itself: the appearance of thickening is due to underlying laminal growth and a layer of superimposed fibrous tissue. General spasm of the spinal muscles guarding motion in the vertebral joints can be tested by watching the body attitude (eg, stiff, military carriage) and by efforts to bend the spine forward, backward, and to the sides. Acute Lumbosacral Angle Syndromes When this happens, Cailliet states that the motion unit will be kyphotic. Manual Therapy for the Low Back and Pelvis – A Clinical Orthopedic Approach (2015). A compression fracture is frequently not evident until several days later when deformity becomes more pronounced. This is especially true in the young. The major neurologic signs found in lumbosacral radiculopathies are listed in Table 12.12, and points in differentiating nerve lesions from root or cord lesions are presented in Table 12.17. to chiropractic research. Slight but smooth movement is permitted upward, downward, forward, and backward within the sacroiliac articulations, and axial rotation occurs around a transverse axis to allow pelvic tilting. In rare instances, the cord may be damaged from violent falls with trunk flexion. Unless the metabolic defect can be corrected, progressive thoracic kyphosis, pulmonary symptoms, disc degeneration and failure, vertebral collapse, and wedge fractures can be expected. In this position, flexion should occur from below upward and a greater stretch is placed on the lumbosacral area than can be achieved in the standing position. Ligament function. Studies by Farfan have shown a distinct correlation between the asymmetry of the facet planes and the level of disc pathology, as well as a correlation between the side of the more oblique facet and the side of sciatica. 2nd ed. Biomechanically, this test is the cephalad representation of Lasegue's straight-leg-raising test. In bending, the knees should not flex. It also tends to assume an anteroflexed position, thus producing the three-dimensional movements of the lumbar spine. If the superior sacroiliac joint or the symphysis pubis is locked, the sacrum and ilium will move as a unit, the thumbs will not separate appreciably, and the sacral tissues (ligaments and spinal muscle attachments) will remain taut. If the spine shows rotation to the right, for example, the patient in a forward bent position can swing his torso into right rotation much more readily than to the left. Curvatures arising from locomotion dysfunctions (eg, pelvic subluxation-fixations, contractures, paralysis) are called curvatures of disturbed motion or dynamic curvatures. There will be a noticeable lumbar scoliosis to the side of involvement. Restricted extension is usually the result of fixation at the posterior motion unit that prevents facet gliding. The lumbar spine is in flexion when a person is supine on a hammock or an extremely soft mattress. The examiner's fingertips should be placed in the lumbar interspinous spaces to evaluate segmental motion. This hardening is usually followed by hypertrophy or exostosis. This is a variant of Lasegue's supine test used by many in lumbago and IVF funiculitis, with the intent of differentiating between lumbago nd sciatica. Pertinent Associated Complaints and Findings. Selected Effects of Hypertonicity in the Lumbosacral Area. They can be best appreciated by test movements that place normal stress on normal or abnormal tissues. Thus, immobility, stress tests, and spinal balance are the most reliable clues. When ligamentous lesions heal, hypertrophic spurs and sometimes bridges may develop locally on the margins of the bones affected. The major predisposing factors to low back pain appear to be a poor sitting posture, a loss of motion within the normal range of lumbar extension, and/or excessive hyperflexion activities. Body balance is most efficient in the standing position when the vertical line of gravity falls through an aligned column of supporting bones. Infrequently, vertebral body fracture is associated.
