INTRODUCTION
• Spine injury refers to insult to the spine
resulting in damage to its osseoligamentous
components with or without associated
neurologic impairment
• It is a frequently-occurring event with
propensity for devastating consequences.
Early recognition and treatment are central to
achieving satisfactory outcomes.
INTRODUCTION - EPIDEMIOLOGY
• USA
• Incidence: 10,000 – 14,000/yr
• Prevalence: 229,000 – 306,000
• Age: 55% in 16-30yrs
• Sex: 81.6% male
• Aetiology: MVA (44.5%), falls (18.1%)
• NIGERIA
• Age: 38.4+/-13.6yrs
• Sex: 82.2% male
• Aetiology: MVA (79.7%), falls (13.4%)
INTRODUCTION - ANATOMY
• Vertebral Column – Fibro-osseous
– 33 Vertebrae
– Soft tissues – IV discs, facet joint capsule, ligaments
• Spinal cord
– Part of CNS
– Neural tissue + coverings
– Blood supply – spinal arteries
AETIOLOGY
• MVA
• Falls
• Sports injuries
• Assault – Firearm, stab injury
• Pathologic fractures – osteoporosis, TB spine
CLASSIFICATION
• STABLE
– A spine injury in which movement of the affected
part would not result in displacement of
fragments
• UNSTABLE
– A spine injury in which movement of the affected
part would result in significant displacement of
fragments thereby causing or aggravating
neurologic injury
PATHOPHYSIOLOGY
• MECHANISMS
• Spine injury
– Traction force
– Direct trauma
– Indirect trauma (commonest) – axial compression, flexion,
flexion-rotation, hyperextension, lateral compression,
distraction
• Cord injury
– Direct trauma
– Compression: displaced bone frags, haematoma
– Disruption of blood supply
PATHOPHYSIOLOGY
• Primary injury
– Caused by initial trauma
• Secondary injury
– Caused by body’s response to initial injury (begins
within minutes, may last for weeks to months)
– Body’s response comprised by
– Inflammation – vascular changes, oedema, hypoxia
– Loss of ATP-dependent processes
– Ionic derangements
– Accumulation of neurotransmitters
– Production of molecules (arachidonic acid, free radicals,
endogenous opioids)
DIFFERENTIAL DIAGNOSIS
• TB spine
• Transverse myelitis
• Tumours
• Degenerative diseases
• Guillain-Barre syndrome
MANAGEMENT
• Pre-hospital
• Resuscitation + spine stabilization
• Log-rolling
• Transportation
MANAGEMENT – HOSPITAL CARE
• Multidisciplinary approach
• Spine injury centre care is best
• Resuscitation
• Clinical evaluation – maintain high index of
suspicion
– History: pain in neck or back, neurologic impairment,
bladder/bowel incontinence, hx of high risk injury,
other injuries
– Examination:
• General exam – Conscious/unconscious, restless,
shock, other injuries
MANAGEMENT – HOSPITAL CARE
• Spine exam
• Inspect head & face for injury
• Inspect spine for deformity, penetrating injury
• Palpate gently for tenderness, bogginess, gap or step
• Other neurological exam
• Carry out power grading for each limb muscle group
• Test for muscle tone and all DTRs
• Anal wink & bulbocavernosus reflex. DRE is mandatory.
• Test each dermatome for sensation and determine the
levels of the various sensory modalities
• Other systemic examination
MANAGEMENT – HOSPITAL CARE
• Investigations
– Confirmatory
• Xrays
• CT
• MRI
• Myelography
– Ancillary
• FBC
• EUCr
• GxM
• Urinalysis
MANAGEMENT – HOSPITAL CARE
• Counselling
• Definitive
– Non-operative
• Indications
– Stable injuries
– Unstable injuries without neurologic impairment
– Patient’s refusal of operative mgt
• Techniques
– Semi-rigid cervical collar
– Halo vest
– Traction
– Minerva jacket
– Thoracolumbar brace
MANAGEMENT – HOSPITAL CARE
• Definitive
– Operative
• Indications
– Unstable fracture with progressive neurologic deficit
– Unstable injuries with neurologic impairment
– Patient’s choice
– To augment spine stability achieve by non-operative means
– Treatment of complications
• Techniques
– Plates
– Rods & screws
– Wires
– Lag screws
MANAGEMENT – HOSPITAL CARE
• Supportive care
– Skin care
– Wash, dry & powder skin
– 2-hrly turning
– No creases or crumbs in sheets
– Bladder and bowel care
– Intermittent, aseptic bladder drainage. Commence bladder
training ASAP
– Bowel training with enemas
– Thromboprophylaxis
– Early physiotherapy
– Drugs
REHABILITATION
• This should be commenced as early as possible
• Physiotherapy
• Promotes neural recovery
• Prevents DVT/PE
• Prevents contractures
• Occupational therapy
• Psychotherapy
COMPLICATIONS
• Early
• DVT
• Pressure sores
• Bladder/bowel dysfunction
• UTI
• Neurogenic shock
• Pulmonary complications – Pneumonia, atelectasis,
ventilatory failure
• Late
• Heterotopic ossification
• Contractures
• Chronic pain
• Autonomic dysreflexia
• Osteoporosis
• Depression
PREVENTION
• Effective & adequate traffic policies (as well as
full enforcement) to reduce RTI
• Creation of new roads, resuscitation of old ones
and establishment of an effective rail system
• Establishment of well-structured, adequately
staffed pre-hospital trauma care teams
• Training and retraining of relevant staff in
management of spine injury with establishment
of purpose-built facilities
• Widespread education of public
CURRENT TRENDS
• ASSISTIVE ROBOTIC EXOSKELETONS
• STEM CELL TRANSPLANTATION (bonemarrow-
derived, iPSCs)
CONCLUSION
• Spine injuries are a clear and present danger
to our economic stability. Apart from being
quite costly to manage, outcomes are
sometimes discouraging despite best care.
• Efforts geared toward prevention will
certainly reduce the burden of this problem
on society as a whole.
