causes of low back pain

- acute low back strain - instability - osteoarthritis - intervetebral disk degeneration - herniation of the intervetebral disk

lumbar region

- bears most weight of the body - most flexible region of spinal column - contains nerve roots that are vulnerable to injury or disease - poor biomechanical structure

diagnostic tests

- conventional x rays - myelogram - MRI, CT scan - epidural venogram or discogram - electromyogram

herniated intervetebral disk (slipped disk)

- intervetebral disk is interposed between the adjacent surfaces of vertebral bodies from the cervical axis to the sacrum - result of natural degeneration with age or repeated stress and trauma to spine - most common sites L4-5 and L5-S1 (may also happen at C5-6 and C6-7) - herniation could also be result of spinal stenosis

acute low back pain

- lasts 4 weeks or less - associated with some type of activity that causes undue stress - symptoms may not appear right away - muscles get tight or spasm

clinical manifestations of herniated intervertebral disk

- low back pain - positive straight leg test - reflexes may be depressed or absent - paresthesia or muscle weakness - bowel and bladder incontinence or impotence

post op implementation for cervical disk

- maintain proper alignment of the spine (wear c collar, log roll) - monitor vital signs and pain - monitor for respiratory difficulty - encourage coughing and deep breathing - monitor for hoarseness and inability to cough effectively - monitor wound drainage - check for CSF - monitor for sudden radicular pain

degenerative disk disease (DDD)

- narrowing and lessening of the intervetebral disks - progressive degeneration = normal process of aging - thinning of disk occurs as the nucleus pulposus dries out and shrinks - compression of the nerve roots and cord may occur - nuclear material may herniate and compress on the nerve root

chronic low back pain: spinal stenosis

- narrowing of the vertebral canal or nerve root canals - caused by encroachment of bone in the space - may be congenital or acquired thru degenerative or traumatic changes in the spine

overall goals

- satisfactory pain relief - avoid constipation - learn back sparing practices - return to normal acitivites

diagnostics

- straight leg raises positive = pain with leg lifted to 30-70 degrees = nerve root compression and likely herniated disc - CT and MRI scans

intervetebral lumbar disc damage

- structural degeneration of the lumbar disk is often caused by degenerative disk disease (DDD) - acute herniated intervetebral disk

surgery

indications similar to those with low back pain - neurologic symptoms not resolved with conservative treatment, trauma Types of surgery is similar to lumbar: diskectomy, laminectomy, and spinal fusion Monitor client post op: spinal cord edema (respiratory distress an worsening neurologic status of the upper extremities) May need a halo or cervical collor post op

risk factors of low back pain

lack of muscle tone - excess weight - poor posture - smoking - stress - job factors (repetitive motion, prolonged sitting)

surgical treatment for herniation

laminectomy diskectomy percutaneous laser diskectomy spinal fusion PLIF

low back pain

local or referred pain at the base of the spine caused by a sprain, strain, osteoarthritis, ankylosing spondylitis, a neoplasm or a herniated intervetebral disk.

interspinous process decompression system (x stop)

made of titanium and fits onto a mount that is placed on vertebrae in the lower back indicated for clients with pain due to lumbar stenosis works by pushing open the spinal cord by pressing against parts of either side of the vertebrae (similar to laminectomy)

goal of management

make episode of acute low back pain an isolated incident

procedures for back pain

minimally invasive, outpatient helps treat back pain and sciatica pain insertion of needle into affected disk via x ray guidance thread wire thru needle and into disk- heat wire. which denervates the small nerve fibers that have grown into cracks and invaded degenerating disk

disk surgical interventions

monitor for CSF leakage - headache (clear or slightly yellow; high glucose - dipstick) monitor for strength in extremities monitor for numbness or tingling avoid extreme knee flexion assist when getting OOB, encourage early ambulation and assist with back brace

post operative nursing implementation for lumbar disk

monitor vital signs and pain and document monitor peripheral neurologic signs - sensation and motor ability instruct on positioning - logroll and pillow placement and activity orders monitor wound and drain site monitor for CSF leaking (color of drainage and headache)- report immediately monitor for urinary retention, constipation

cervical neck sprain or strain

neck pain- almost as frequent as low back pain occurs at C5 to C6 to C7 interspaces diagnosis is determined by history, physical exam, xray, MRI, CT and myelography. EMG to diagnose cervical radiculopathy pain and stiffness in neck paresthesia with herniation, DDD or stenosis

radiofrequency discal nucleoplasty (coblation nucleoplasty)

needle inserted into disc similar to IDET generates energy that breaks up the molecular bonds of the gel in the nucleus up to 20% nucleus is removed = disk decopression

preoperative implementation (disk)

offer reassurance instruct on post operative plan instruct on deep breathing and coughing instruct on log rolling and positioning may need bedrest for a short period of time

spinal fusion

performed if an unstable boney mechanism is present spin is stabilized by creating an ankylosis (fusion) of contiguous vertebrae with a bone graft use of bone (cadaver or donated from iliac crest or fibula) metal fixation with rods, plates, or screws may be implanted infuse bone graft may be used instead of bone

chronic low back pain treatment

reduce pain formal back pain program surgery may be indicated in patients with severe chronic low back pain who do not respond to conservative treatment or continued neurologic deficits

Posterior Lumbar Interbody Fusion (PLIF)

removing disc tissue pressing on the lower spine area, inserting a piece of bone between the vertebrae, and fusing this area with plates and screws. Skeletal System

overall goals for lumbar injuries

satisfactory pain relief return to previous level of activity correct performance of exercises adequate coping adequate self help management

lumbar disk herniation

surgery indicated if 4 weeks of conservative therapy unsuccessful, radiculopathy (nerve root pain) becomes worse, or if loss of bowel or bladder control (cauda equina) is doumented - muscle and sensory loss - tendon relexes are altered - pain is not relieved

laminectomy

surgical excision of part of the posterior arch of the vertebrae (lamina) to gain access to part of the protruding disk and remove - minimal hospital stay

preventing low back pain

teach, teach, teach: - proper body mechanics - maintenance of appropriate body weight - avoid sleeping in the prone position - firm mattress - no smoking and regular exercise

cervical collar

used to treat cervical disk herniation, trauma, post op care holds head in neutral of slightly flexed position may need to wear 24 hours a day inspect skin teach cervical isometric exercises

charite disk

used with degenerative disc disease (DDD) artificial disk made up of high density core between two endplates surgically placed in the spine thru a small hole in the umbilicus after damaged one is removed allows for movement at the level of the implant

interbody cage fusion

uses a hollow threaded cylinder filled with bone graft to fuse two vertebrae
