What is back pain ?

Any pain in the back. It is usually characterized by dull, continuous pain and tenderness in the lower lumbar, lumbosacral, or sacroiliac regions. Sometimes referred to the leg, following the distribution of the sciatic nerve.

how big is the problem
How Big Is the Problem?
  • 2nd most common cause for GP visit .
  • 70% of the world adults will experience at least one disabling episode in their lives.
  • Each year, 15-20% will have back pain.
  • Most common cause of disability for persons < 45 years.
  • Disability due to back pain, particularly work absence, has increased significantly in the last 30 years.
how big is the problem4
How Big Is the Problem?
  • In western countries, back pain is the most common cause of sickness-related absences from work.
  • 8% of US population is disabled.
  • Costs to society: $20-50 billion/year.

In UK:

  • 7% of adult population consult their GP each year with back pain.
  • Costs to society: £ 500 million/year.

In US:

Classification of back pain

Back Pain

chronic

recurrent

acute

slide6

Acute V.S Chronic

  • Most acute episodes improve regardless of the treatment used, and the patient resumes normal activity within 6 weeks.
  • Chronic pain develops in only 10% to 15% of patients but it can cause significant distress and functional disability and requires aggressive treatment.
slide7

Causes of Back Pain

Psychogenic factors

(somatization)

Systemic causes

Back Pain

uncomplicated

Referred pain

complicated

slide8

Uncomplicated Back Pain

  • Caused by some kind of structural problem (bone, muscle, joint, disc, nerves associated with lumber vertebrae or pelvis, tendon or ligament).
  • The most common mechanisms seem to be injury to muscles & ligament, osteoarthritis, degenerative disc disease, & malalignmet of spinal cord.
slide9

Injury to muscle & Ligaments

  • Includes strain, sprain or contusion of muscle and/or ligaments.
  • Occur when performing day-to-day activities, or from direct trauma such as a fall.
  • It the most common cause of acute low back pain, especially in young adults.
  • Patients with muscle & ligament injuries usually develop pain after unusual physical activity.
slide10

Degenerative Joint Disease (Osteoarthritis)

  • Is the most common cause of chronic low back pain in the elderly.
  • Loss of articular cartilage, osteophyte formation, and articular surface irregularity impair joint function and at times can lead to inflammation and pain.
  • Patients can experience pain in different situations (e.g. after unusual positioning or even while sleeping on a soft mattress).
slide11

Degenerative Disc Disease

  • Weakening of the fibrous outer ring of an intervertebral disc (the annulus fibrosus).
  • Can cause the gelatinous center of the disc ( the nucleus pulposus) to bulge or to herniate (extrude or rupture) into the spinal canal.
  • The discs most commonly involved are L3-L4, L4-L5, L5-S1.
slide12

Malaignment

  • Motion restriction of spinal structures such as the facet joints, the sacroiliac joint and/or the vertebral bodies.
slide13

Spondylolysis & Spondylolisthesis

  • Spondylolysis describes any sitution where there is a break in the integrity of the neural arch.
  • The principal cause is an aquired defect in pars interarticularis due to fracture.
  • Spondylolisthesis is where defect causes slippage of vertebra on the on below.
slide14

Other Causes

  • Fractures (usually a compression fracture of the vertebral body, often caused by minor trauma in older people with Osteoarthritis).
  • Type of occupations (workers in occupation requiring lifting heavy objects).
  • Smoking.
  • Obesity.
slide15

Complicated Back Pain

  • Structural with nerve root compromise (sciatica).
  • It is a condition in which pain, numbness, paresthesia &/or muscle weakness reflect injury to the spinal root or PN.
  • The most common cause is herniation of IV disc.
slide16

Spinal Stenosis

  • Back & leg symptoms associated with narrowing of the lumbar spinal canal seen on CT or MRI scanning.
  • The origin of the pain is may be related to bony pressure on multiple nerve roots, leading to ischemia of the nerves & pain.
  • The origin of the narrow canal may be congential.
slide17

Systemic Causes

  • Are rare (less than 1% of all cases).
  • They include cancer, infections, inflammatory arthritis and Paget’s disaese.
slide18

Referred Pain

  • Referred pain from abdominal or pelvic structures can arise from structures such as muscle, ligaments, or joint capsules.
  • The most common are: acute pancreatitis, pyelonephritis, pelvic inflammatory disease, dysmenorrhea, posterior peptic ulcer, abdominal aneurysm & cholecystitis.

Because the majority of physician visits for low back pain are to the GPs, family physician must has good skills in approaching, assessing & managing the patient with low back pain.

neurological examination
Neurological examination
  • Involving the lower extremities specifically (why?)
  • Inspection
  • For each neurological level we shall test
          • The muscles power, reflexes and sensory areas.
additional examination
Additional examination
  • The abdomen.
  • in males what else to be examined and why ?
  • In females and why? ¼ Bonus.
remember
Remember

It is never toooooo late for your

lunch .

investigations
INVESTIGATIONS
  • DO YOU THINK THAT ALL PATIENTS WITH LOW BACK PAIN PRESENTING TO PRIMARY CARE PHYSICIAN NEED INVESTIGATIONS ?

* MOST PATIENTS WITH LOW BACK PAIN DO NOT NEED INVESTIGATIONS.

investigations47
INVESTIGATIONS
  • 1- Spinal X-rays

* Are required only if the pain is associated with certain red flag symptoms or signs, which indicate a high risk of more serious underlying problems .

x rays
X- rays
  • If the pain :

1- Starts before the age of 20 or after 50

years.

2- Is persistent and a serious cause is

suspected.

3- Is worse at night or in the morning , or when an inflammatory arthritis (e.g. ankylosing spodylitis) , infection or spinal tumour may be the cause.

4- Is associated with a systemic illness, fever

or weight loss

5- Is associated with neurological symptoms or

signs.

mri ct
MRI & CT
  • Used when suspecting spinal cancer, herniated disc or infection.
  • MRI is preferable to

CT scanning when neurological signs and symptoms are present.

* Note : If red flags are present , MRI should be undertaken even if X-ray is normal.

investigations50
INVESTIGATIONS
  • Bone scans
  • Useful in infection and malignancy
  • Full blood count, ESR and biochemical tests

- Required only when the pain is likely to be due to malignancy , infection or a metabolic disease

management
MANAGEMENT
  • ACUTE LOW BACK PAIN
  • DEPENDS ON THE INDIVIDUAL STATUS OF YOUR PATIENT
    • MILD / MODERATE PAIN
      • PARACETAMOL, ASPIRIN, OTHER NSAIDs
      • SITTING FOR <20 min
      • AVOID STRENOUS ACTIVITY
      • GENTLE STRETCHING EXERCISES
      • PREVENTIVE EDUACTION
      • FOLLOW UP VISIT IN 1 WK
management52
MANAGEMENT
  • HOWETHER, SITTING IS MECHANICALLY STRESSFUL FOR THE BACK AND CAN BE SIGNIFICANT PROBLEM FOR PEOPLE WITH LOW BACK PAIN.
  • INSTRUCTIONS SHOULD INCLUDE:
  • USING CHAIR WITH GOOD LUMBAR SUPPORT
  • GETTING UP AND STRETCHING FREQUENTLY
  • TAKING SHORT WALKS THAT HELP LIMBER THE BACK
  • AS SYMPTOMS DECREASE , ACTIVITY SHOULD BE GRADUALLY INCREASED
slide53

MANAGEMENT

  • SEVERE PAIN
    • OPIATE ANALGESICS / MUSCULAR RELAXANTS
    • NSAIDs
    • BED REST (2-4 days) THEN, GRADUAL INCREASE IN ACTIVITY
    • ICE PACK APPLICATION (20 min) FOR (1-2 days)
    • RETURN VISIT IN (3-5 days)
  • IF SYMPTOMS NOT IMPROVED
    • CT / MRI / CONSULT BACK SURGEON
management54
MANAGEMENT
  • ACTIVITY IS ADVICED (NON-STRENOUS)
  • IF SYMPTOMS PERSIST (>4-6 WK) REFER YOUR PATIENT TO PHYSIOTHERAPIST
  • EARLY RETURN TO ACTIVITY AND WORK SHOULD BE ENCORAGED
  • RECURRENT PAIN
    • REVIEW OF MANAGEMENT IN THE PAST
    • FOLLOW-UP SHOULD BE MORE INTENSIVE
    • WITH IMPROVEMENT OF EPISODES,PATIENT SHOULD BE ENCOURAGED TO DEVELOP AN EXERCISE AND CONDITIONING PROGRAM THAT STRETCHES AND STRENGTHES THE BACK
management55
MANAGEMENT
  • CHRONIC LOW BACK PAIN
  • MANAGEMENT OF CHRONIC LOW BACK PAIN INCLUDES:
    • EXERCISE
    • EDUCATION
    • PSYCHOSOCIAL SUPPORT
    • MEDICATIONS (PARACETAMOL ,NSAIDs ) for mild and moderate chronic pain; (OPIATES (for severe chronic pain
patient education
PATIENT EDUCATION
  • EDUCATION AND EMOTIONAL SUPPORT ARE IMPORTANT COMPONENTS OF EFFECTIVE MANAGEMENT OF LOW BACK PAIN
patient education57
PATIENT EDUCATION
  • ACUTE LOW BACK PAIN

REASSURE THE PATIENT THAT THE PAIN WILL IMPROVE; DISABILITY IS NOT LIKELY

PROVIDE A CLEAR,CONFIDENT EXPLANATION FOR THE PAIN

INSTRUCTIONS ABOUT PRESCRIBED ACTIVITY LEVEL AND THERAPY
