DESCRIPTION

Dr Arun L Naik is a Spine Surgeon practicing in India Bangalore for 14 years. He was trained at AIIMS New Delhi in 2000. He is well known for his surgery for ''failed back surgery syndrome'' where previous surgery was gone wrong. He has expertise in 'minimal invasive key hole spine surgery'' . He operates on complex spinal cord tumors which are challenges to any surgeon. Dr Naik is one of the few neurosurgeons in India to operate on cranio vertebral junction with excellent surgical results. Spinal cord injuries are special areas of interest to him. He has successfully treated hundreds of spinal injured patients many of whom are walking today. He has trained many surgeons in developing spine surgery technique.

Flexion: bilateral facet dislocations wedge fractures of anterior vertebrae,

Disruption of the disc with forward bilateral facet dislocations, and fracture of the pedicle.

Flexion with rotation: Causes unilateral facet dislocation fracture of the vertebra, rupture of supporting ligaments.

Vertical compression/axial loading These usually stable injuries "burst" fracture

Trauma to the cord itself Vertebral columnDistractional forces associated with flexion,

extension, dislocation, or rotationStretching or shearing of the neural elementsCompression and contusion from bone

fragments, ligaments, and hematoma within the spinal canal

ParamedicsIntubation?Immobilization

Prolonged time spent in transport

Respiratory compromise

Pain and discomfort in conscious patient

Pressure sore in prolonged use

Airway with attention to spinal protectionBreathingCirculationDisability: NeurologicalExposure of the entire patient for signs of

injury

Page 11: Spine surgeon Dr Arun L Naik Bangalore india

Nasotracheal intubation (ATLS ): Fallen out of practice

Cricothyroidotomy has also become less common

Intubating laryngeal mask airwayLighted styletElastic bougie devices

Page 12: Spine surgeon Dr Arun L Naik Bangalore india

• Diminished or absent airway protective mechanisms: intracranial injury or other pathology

• Evidence of airway obstruction in the multiple trauma

• Acute respiratory failure in patients with injuries at C4

• Thoracoabdominal trauma• Inability to cough, clear secretions

Page 13: Spine surgeon Dr Arun L Naik Bangalore india

The ideal MAP: 80 to 100 mmHgHypertension: Risk of intramedullary

hemorrhage and edemaAdequate volume resuscitationVasopressor therapy

Page 14: Spine surgeon Dr Arun L Naik Bangalore india

Spinal Shock• Temporary

suppression of all or most reflex activity below the level of injury

• Occurs immediately after injury

• Intensity & duration vary with the level & degree of injury

Neurogenic Shock• The body’s response to the

sudden loss of sympathetic control

• Distributive shock • Occurs in people who have

SCI above T6 (> 50% loss of sympathetic innervation)

• Paralyzed, hypotensive patient with warm, dry, hyperemic extremities, and bradycardia

Conus medullaris syndromeCauda equina syndrome

Page 24: Spine surgeon Dr Arun L Naik Bangalore india

• Flexion-rotation force to the spine producing an anterior dislocation or by a compression fracture of the vertebral body• There is often anterior spinal artery compression so that the corticospinal and spinothalamic tracts are damaged• Loss of power as well as reduced pain and temperature sensation below the lesion

Page 25: Spine surgeon Dr Arun L Naik Bangalore india

Older patients with cervical spondylosis

Hyperextension injury Flaccid (lower motor neuron) weakness of the

arms and relatively strong but spastic (upper motor neuron) leg function

Sacral sensation and bladder and bowel

function are often partially spared

Page 26: Spine surgeon Dr Arun L Naik Bangalore india

• Hyperextension injuries with fractures of the posterior elements of the vertebrae

• Good power and pain and temperature sensation but there is sometimes profound ataxia due to the loss of proprioception, which can make walking very difficult

Page 27: Spine surgeon Dr Arun L Naik Bangalore india

Stab injuries, lateral mass fractures of the vertebrae

Power is reduced or absent Pain and temperature

sensation are relatively normal on the side of the injury

The uninjured side therefore has good power but reduced or absent sensation to pin prick and temperature

Page 28: Spine surgeon Dr Arun L Naik Bangalore india

Loss of bladder, bowel and lower limb reflexes

Injury to the lumbosacral nerve roots results in areflexia of the bladder, bowel, and lower limbs

Secondary Injury

Page 30: Spine surgeon Dr Arun L Naik Bangalore india

Hypotension should be avoidedOptimal blood pressure in the first week after

SCI through aggressive volume expansion and the use of pressor agents may improve outcome

SBP in adults should be kept 90 mmHg
