Aetiological factors
- Trauma
- Inflammatory, e.g., rheumatoid arthritis, ankylosing spondylitis, etc.
- Degenerative: Spondylosis (degenerative disease), prolapsed intervertebral disc, spondylolisthesis
- Neoplastic: Usually secondary tumors
- Infection: Pyogenic, non-pyogenic (Tuberculosis-Prott’s disease)
- Spinal stenosis: Congenital degenerative
- Others: Kyphoscoliosis
Clinical Features
- History at presentation includes the following:
- Pain: Sharp and localized, chronic and diffuse
- Referred pain (sciatica): Pain radiates into the lower limb, may be aggravated by coughing, straining, etc.
- Stiffness
- Deformity, e.g., TB spine
- Numbness or parasthesia in the lower limb
- Urinary retention or incontinence (can be due to pressure or cauda equina)
- There may be a history of trauma, heavy lifting, neoplasm, connective tissue disorder like rheumatoid arthritis.
- Physical findings at presentation are demonstrable by:
- Inspection
-Skin-may show scars, pigmentation, abnormal hair.
-Shape and posture may be abnormal and suggestive.
- Palpation
-Feeling for tenderness is likely to elicit it.
-Motion-May be impaired.
-Sensation-May be diminished if nerves are involved.
-Reflexes-May be diminished if nerves are involved.
-Straight leg raising test. Discloses lumbosacral root tension.
- Examining the other systems.
Investigations
- Plain radiographs: Anteroposterior, lateral, and oblique views of spine may shoe:
- Osteophytes and disc degeneration in spondylosis
- Loss of lumbar lordosis, which signifies muscle spasm due to pain
- Anterior shifts of an upper segment upon lower, which indicates spondylolisthesis.
- Bone destruction with sparing of intervertebral discs is noted in tumours
- Sclerotic metastasis are seen in Ca prostate
- Bone destruction in infective conditions, e.g., TB. There may be a gibbus (sharp angulation) deformity.
- Radioisotope scanning: May pick up areas of increased activity suggesting a fracture, silent metastasis, or local inflammatory lesion.
- Computed tomography: May pick up structural bone changes, e.g., fracture, tumor, and intervertebral discs prolapse.
- Magnetic resonance imaging (MRI): Discs, nerves, and other soft tissues are clearly seen.
- Other investigations include:
-Those based on the likely working diagnosis, e.g., abdominal ultrasound in suspected tumours.
-Erythrocyte sedimentation rates in suspected tumor, TB, connective tissue disease.
Management
Most cases of disc prolapse will improve on conservative management.
- Give analgesics to control pain ibuprofen 400mg TDS. In suspected tuberculosis without neurological deficit, a trial of anti tuberculosis therapy can be given. If there is no improvement in 3 to 4 weeks, refer to the specialist.
- Initiate physiotherapy for spondylosis and spondylolisthesis, and where nothing specific is picked up on imaging.
- Stable fractures will heal conservatively on bed rest (orthopedic bed). A hard lumbosacral corset may be fitted after 6-8 weeks and used for further 4-6 weeks or until the pain is bearable. For unstable fractures, refer to a suitable facility for further management.
- In suspected tumours, neurological deficit, pain that is not improving, etc., refer the patient to a level 5 facility and above.
