  • Thanks for sharing the useful slides with us. Images clearly mention all the facts related to Spine. Lumbar disc herniations occur in the lower back, most often between the fourth and fifth lumbar vertebral bodies or between the fifth and the sacrum. Symptoms can affect the lower back, buttocks, thigh, anal/genital region (via the Perineal nerve), and may radiate into the foot and/or toe. The sciatic nerve is the most commonly affected nerve, causing symptoms of sciatica.

Transcript

  • 1. J.J.M MEDICAL COLLEGE DAVANGERE SEMINAR ON
  • 2. HISTORY Aurelianus (5th century) clearly described thesymptoms of SCIATICA. Andreas Vesalius (1543) first described theintervertebral disc. Middleton & Teacher (1911) described a case ofparaplegia following attempting to lift heavy weight fromfloor on postmortem they found fibrocartilage in extraduralspace. Elseberg (1928) described Chondromas derived fromdisc of cervical region.
  • 3.  Stookey (1928) described cartilaginous compression thought as chondromas responsible for clinical prersentation. Dandy (1929) reported removal of a disc tumour or chondroma from patients with sciatica. Mixter and Barr (1934) described disc herniation as the cause of Sciatica.
  • 4.  Peet& Echols (1934) referred to as Chondroma or Ecchondrosis was really protrusion of intervertebral disc. Lindblom(1948) first described DISCOGRAPHY. Lyman Smith (1963) described CHEMONUCLEOLYSIS. Kambin & Gellman (1983) reported percutaneous approach for lumbar discectomy.

  • 30. DISC DEGENERATION
  • 31. PATHOPHYSIOLOGY OF LUMBARINTERVERTEBRAL DISC PROLAPSE With aging, vascular channels start to fail and vascular diffusion of nutrients decrease thus number of viable chondrocytes in the nucleus pulposus diminishes Synthesis rate & concentration of proteoglycans decreases & proportion of collagen increase in nucleus pulposus Water binding capacity of the nucleus decreases Nucleus becomes more fibrous & stiffer Nucleus is less able to bear & disburse load, transferring load to the posterior annulus

Neurofibroma, ependymoma)Disc level• Herniated nucleus pulposus• Stenosis (Canal or recess)• Infection: Osteomyelitis or discitis ( with nerve root pressure)• Inflammation: Arachnoiditis• Neoplasm: Benign or malignant with nerve root pressure
  • 58. EXTRASPINAL CAUSESPelvis• Cardiovascular conditions (eg. Peripheral vascular disease)• Gynaecological conditions• Orthopaedic conditions ( osteoarthritis of hip, Muscle related disease, Facet joint arthropathy)• Sacroiliac joint disease• NeoplasmPeripheral nerve lesions• Neuropathy (Diabetic, tumour, alcohol)• Local sciatic nerve conditions (Trauma, tumour)• Inflammation (herpes zoster)
  • 59. KEY DIAGNOSTIC POINTSLUMBAR DISC PROLAPSE Leg pain greater than back pain Neurological deficit presentANNULAR TEARS Back pain greater than leg pain Bilateral SLRT positiveFACET JOINT ARTHROPATHY Localized tenderness present unilaterally over joint Pain occurs immediately on spinal extension Pain exacerbated with ipsilateral side bending
  • 60. SPINAL STENOSIS Back and/or leg pain develops after walks a limited distance. Flexion relieves symptoms No neurological deficit Pain not reproduced on SLRTMYOGENIC OR MUSCLE RELATED Pain localised to affected muscle Pain increases on prolonged muscle use Pain reproduced with sustained muscle contraction against resistance Contralateral pain with side bending

  • 65. REDUCTION IN THE HEIGHT OF THE PEDICLE
  • 66. FORWARDDISPLACEMENT OF L3 OVER L4
  • 67. MYELOGRAPHY
  • 68. DISADVANTAGE OF MYELOGRAPHY• Myelographyis capable of showing the level at which the pathology lies but fails to show the nature of the lesion or its precise location in the anatomic segment .
  • 69. DISCOGRAHY
  • 70. USES OF DISCOGRAPHY• To evaluate equivocal abnormality seen on myelography, CT or MRI• To isolate a symptomatic disc among multiple level abnormality• To diagnose a lateral disc herniation• To establish contained discogenic pain• To select fusion levels• To evaluate the previously operated spine
  • 71. CT DISCOGRAPHYUSES• To determine whether the disc herniation is contained, protruded, extruded or sequestrated.• To evaluate previously operated lumbar spine to distinguish between mass effect from scar tissue or disc material.
  • 72. COMPUTED TOMOGRAPHYADVANTAGES• CT is an extremely useful, highly accurate & noninvasive tool in the evaluation of spinal disease.• CT provides superior imaging of cortical and trabecular bone compared with MRI.• It provides contrast resolution and identify root compressive lesions such as disc herniation.• It also helps to differentiate between bony osteophyte from soft disc.• It helps to diagnose foraminal encroachment of disc material due to its ability to visualize beyond the limits of the dural sac and root sleeves.
  • 73. LIMITATIONS• It cannot differentiate between scar tissue and new disc herniation• It does not have sufficient soft tissue resolution to allow differentiation between annulus and nucleus.
  • 74. MAGNETIC RESONANCE IMAGING• It allows direct visualization of herniated disc material and its relationship to neural tissue including intrathecal contents.
  • 75. INDICATIONS FOR SPINE IMAGING• Presence ofunderlying systemic disease• Progressive neurological deficits• Cauda equine syndrome• Candidate for therapeutic intervention• Failed clinically directed conservative therapy
  • 76. CONTRAST ENCHANCED MRI• Here GADOLINIUM labeled diethylenetriaminepentaacetate (Gd-DTPA) administered intravenously and MRI scan done.ADVANTAGES• Display the inflammatory reaction critical to the pathophysiology of radicular pain or radiculopathy• Allows discrimination of scar from recurrent disc.
  • 77. OTHER DIAGNOSTIC TESTS• ELECTROMYOGRAPHY – to rule out peripheral neuropathy.• SOMATOSENSORY EVOKED POTENTIALS (SSEP) – to identify the level of root involvement• POSITRON EMISSION TOMOGRAPHY
  • 78. TREATMENT• CONSERVATIVE• SURGICAL
  • 79. CONSERVATIVE Majority of disc prolapse respond well toconservative therapy. Resolution of first discprolapse takes place approximately 75% ofpatients over a period of 3 months.
  • 80. BED REST
  • 81. PHYSIOTHERAPY
  • 82. EXERCISESGENERAL RULES FOR EXERCISE• Do each exercise slowly. Hold the exercise position for a slow count of five.• Start with five repetitions and work up to ten. Relax completely between each repetition.• Do the exercises for 10 minutes twice a day.• Care should be taken when doing exercises that are painful. A little pain when exercising is not necessarily bad. If pain is more or referred to the legs the patient may have overdone it.• Do the exercises every day without fail.
  • 83. FOR ACUTE STAGEBRIDGING EXERCISE KNEE HUGS
  • 84. FOR RECOVERY OR SUBACUTE STAGE EXTENSION CONTROL HAMSTRING STRETCH KNEE ROLLS
