3 Spinal Stenosis Predominant in elderly Narrowing of lumbar spinal canal Pain worsened by standing,walking Relieved by rest,sitting and lying down Numbness or weakness in legs(psudoclaudication)
4 Neoplasms Most common is metastatic Ca Waist –level or midback pain not relieved by lying down Increasing in severity & aggravated by activity Past hx of Ca : breast,lung,prostate,GIT,GUT Myeloma is the commonest primary tumor
5 Infections Vertebral osteomyelitis Secondary to spinal procedures :LP,disk surgery Tenderness to percussion of affected vertebrae Fever absent in up to half of pts.
6 Ankylosing Spondylitis Seronegative spondyloarthropathy Morning spinal stiffness Symptomatic improvement with exercise HLA-B27 positive (immune disease) Films of sacroiliac joint may show narrowing of the joint space and active sclerosis (sacroiliitis)
7 Psychogenic Disease Depression Somatization Malingering Normal Physical Examination
8 Cauda Equina Syndrome Injury by any process that compromises the spinal canal below the L-1 level. Massive midline disk herniation is the most common cause. In 90% urinary retention. Saddle anesthesia: reduction in sensation over the buttocks, upper posterior thighs and perineum.
9 Workup History Physical Examination Neurologic Examination Radioimmaging Management Back exercises
10 History Pain characteristics: quality, location, onset, radiation. Fever, Neurological deficits: Bladder dysfunction, saddle anesthesia. Hx of recent injury. Prior hx of cancer. Hx of recent lumbar puncture. Hx of prolonged use of corticosteriod.
11 Aggravating and relieving factors. Impact of back pain on daily activities. Emotional and social stressors. Check for depression.
12 Physical Examination Examine the back with patient standing and back uncovered. Inspect for asymmetry, muscle bulk, posture, spinal curvature. Assess flexibility. Palpate for focal tenderness, masses. SLR Test.
13 Neurologic Examination Test for S1 root function (L5-S1 disk): Plantar flexion against resistance, ankle deep tendon reflexes and lateral foot sensation. Test for L5 root function (L4-L5 disk): dorsiflexion of the ankle and big toe against resistance and sensation on the anterior, medial dorsal foot.
33 Cont… Usually localized to lower cervical levels Narrowing of neural foramina causes root impingement & pain Radiating pain of affected root, paresthesia, numbness & weakness may be associated
34 Cont… C-5 root compression: Involves anterosuperior shoulder & anterolateral aspect of upper arm & forearm Decreased biceps jerk & weakness of elbow flexion found in examination
35 Cont… C-6 root compression: Affects the dorsoradial aspect of forearm & thumb C-7 root compression Alters sensation in the middle of hand
36 Inflammatory disease (Rheumatoid) Pain worsening in the morning Symmetric polyarthropathy & subluxation at C1-2 are charactiristic In spondyloarthropaties, neck pain occurs as diffuse back & sacroiliac discomfort
37 Cont… In polymyalgia rheumatica neck pain accompanies aching discomfort & stiffness of shoulder & hip girdle
38 Malignancy Metastasis to spinal cord or vertebral bodies may produce pain that is worse at night or while bending down
39 Referred pain Coronary ischemia, pain worsen by physical activity Concurrent arm pain, simulate cervical radiculopathy Esophageal disease, referred pain to neck
41 Work up History: Precipitating events Aggravating & alleviating factors Area of maximal tenderness Radiation Numbness or weakness in the extremities
42 Cont… Coarse of the disease Past history of similar problem Previous medication Symptoms of coronary artery disease or meningeal irritation
43 Examination Visualization of neck, thorax, & upper extremities Assessment of neck motion ( flexion, extension, left & right lateral flexion & left & right rotation) Palpation of the neck ( point of local tenderness)
