Q

What is an internal disc derangement?

A

Tears in the inner laminae of the disc (are no pain fibers there) commonly occurring in posterior disc due to the daily flexion loading (or less commonly, extension) microtraumas of life. The nucleus pulposus migrates into the tears, which are usually posterior. With previous disc derangement, pain fibers can grow into the inner ring. The direction of herniation is opposite to the direction of the load.

Q

What does the history of a disc derangement look like? What is the quality of pain? Onset is due to what? What is the chief complaint? What is a classic triad? Is there referred pain?

A

BACK PAIN: deep, achy, poorly localized and usually more midline or bilateral. Pain is constant or intermittent with varying degrees of severity. ACUTE: pain can be severe, sharp, stabbing with sudden movements aggravated by lumbar spine movement.

Onset may be associated with trauma (heavy lifting) but more often repetitive microtrauma.

CHEIF COMPLAINT: sitting intolerance. Sitting rapidly aggravates LBP and it may be relieved by standing.

Dejerine’s triad: straining with bowel movements, coughing or sneezing may induce LBP

Referred pain: unilateral or bilateral referral into buttock or LE, usually not below the knee. Back pain is greater than leg pain. Leg pain is non-dermatomal and there may be non-dermatomal paresthesia or weakness.

30
Q

What would you notice with the physical in a disc derangement?

A

Pain centralization is key: usually into extension for a posterior disc derangement

Posture: normal or flexion antalgia, lateral pelvic shift

AROM: painful and reduced, usually into flexion for a posterior disc derangement

Minor’s sign

Valsalva and orthopedic tests promote spinal compression may be painful in acute phase

SMRs are NORMAL
Tension tests: negative for LE sx

Interspinous spaces tender to palpation

31
Q

What special studies would you run on a pt with suspected disc derangement?

A

Imaging is NOT indicated unless as consideration for surgical tx.

A high intensity spot on MRI may suggest annular fissure that is inflamed or actively healing (+LR 1.5-5.9)

Presents of high intensity zone (HIZ) correlates with discography findings. Discography is considered to be gold standard, but this is controversial. Positive test must reproduce the pts CC and the dye must demonstrate internal derangement.

32
Q

What is the gold standard for special studies in disc derangement? Tell me more

A

Discography is considered to be gold standard, but this is controversial.

Positive test must reproduce the pts CC and the dye must demonstrate internal derangement. And the HIZ from MRI correlates with discography findings.

33
Q

How do you manage patient with disc derangement: (2x2 box) and what to do if conservative care fails?

A

Limit bed rest <2 days and return to activity

CMT: joint manipulation into pain centralizing or directional preference, flexion-distraction therapy.

STM: stretch hamstrings

Behavior Mod: hip hinging, abdominal bracing

Exercise: directional preferences exercises like McGill’s big 3

If conservative care fails:

  • epidural injections
  • spinal fusion
  • IDET (Intradiscal Electrothermoplasty) or PIRFT (Percutaneous Intradiscal Radio-Frequency Thermocoagulation)
34
Q

How does IDET (Intradiscal Electrothermoplasty) work?

A

Using fluoroscopic guidance (real time x-ray), your surgeon inserts a hollow needle with a catheter (flexible tube) and electrode into the intervertebral disc. The catheter encircles the disc’s annulus fibrosis. The electrode is sufficiently heated to destroy small nerve fibers that have grown into the damaged disc and cause pain. The heat also seals small tears or cracks called fissures and stimulates the body’s production of proteins to strengthen the disc.

Complications are rare and may include infection, nerve damage, or disc damage.

Ref: https://www.coloradospineinstitute.com/treatment/surgical/idet/

35
Q

How does PIRFT (Percutaneous Intradiscal Radio-Frequency Thermocoagulation) work?

A

The radiofrequency probe is placed into the center of the disc rather than around the annulus, and the device is activated for only 90 seconds at a temperature of 70 degrees centigrade. The mechanism of action is not precisely understood, but is thought to be related to reducing the nocioceptive pain input from the free nerve ending in the outer annulus fibrosis.

Ref: https://www.excellusbcbs.com/wps/wcm/connect/568f0e53-3f2a-4cf5-995b-b358879fc3c9/perc_idet+tac+18+%232.pdf?MOD=AJPERES&CACHEID=568f0e53-3f2a-4cf5-995b-b358879fc3c9

36
Q

What is the prognosis for someone with internal disc derangement?

A

Conservative care may take 2+ months for healing.

Aggressive treatment shows mixed prognosis results

37
Q

What is lumbar facet syndrome?

A

Pain originating from facets, their capsules, and adjacent soft tissues. It includes a spectrum of structural changes such as osteoarthritis, capsular tears, synovial cysts, and/or articular cartilage.

Lifetime prevalence with rigorous dual block criteria is ~15%. In older population of patients referred from rheumatologists, the prevalence rises to 40%.

38
Q

What is a history for lumbar facet syndrome. Quality of pain, location, what aggravates it, MOI, pain referral pattern.

A

Deep achy back pain localized in paravertebral area (not midline). ACUTE phase: may be sharp with sudden movements

Pain is aggravated by hyperextension, rotation, lat flexion, walking downhill.

Least painful: walking and sitting

MOI: trauma, secondary to degeneration, or more commonly due to chronic postural or repetitive loads

Pain referral: anterior hip and thigh, posterior leg. Non-dermatomal, may not be contiguous, may refer as far as the foot.

39
Q

What will you notice in a physical with suspected lumbar facet syndrome?

A

Pain is aggravated with:

  • extending up from flexion (standing up from a forward bend)
  • active hyperextension
  • passive extension
  • extension + rotation

(-) Kemp’s Test is pertinent negative against facet syndrome diagnosis.
(+) Kemp’s Test creates leg pain, suspect radiculopathy (nerve root) lesion

Static palp over facets is tender.
Motion palp reveals restricted joints

These tests are always negative:

  • pain centralization (strong pertinent negative)
  • valsalva
  • flexion based loading tests
  • SLR
40
Q

What is a pertinent negative for lumbar facet syndrome?

A

(-) Kemp’s Test

(+) pain centralization

41
Q

For a lumbar facet syndrome, what special studies should you order?

A

Imaging is NOT indicated.

Diagnostic facet block can be used to diagnose facet syndrome-this must be done prior to more aggressive Tx options

42
Q

How is a diagnostic facet block performed?

A

It’s performed by anesthesiologist.

Intra-articular anesthetic injections with a double block or triple block protocol:

  • inject the facet with short acting anesthetic and have patient note when pain returns
  • repeat with longer lasting anesthetic injection
  • for triple block, repeat a 3rd time with saline injection
43
Q

What is the management plan with a pt with lumbar facet syndrome? 2x2 box

A

CMT: Spinal manipulation applied to painful joint restrictions, flexion-distraction therapy

STM: manual therapy for impaired thoracic extension, tight hip external rotators, tight hip anterior joint capsule or hip flexors, tight latissimus dorsi

BM: modify activities that promote extension

Exercise: prescribe core stability exercise program McGill’s big 3: side bridge, quadruped, curl up

If conservative care fails:

  • therapeutic facet blocks
  • radio frequency ablation (destroy the nerves)
44
Q

What is the theory of acute locked low back?

A

Due to entrapped meniscoid or disc fragment lodged in the end plate

45
Q

What is the history for acute locked low back?

A

Sudden onset (or slower onset over a few hours) of agonizing pain and inability to stand erect

May be triggered by forward flexion or sudden unguarded movement

Pain is slightly off midline with possible referral to ipsilateral thigh

Pt must brace with:
- walking, coughing, sneezing 🤧

46
Q

What would you observe in a physical exam with acute locked low back?

A

Antalgic posture: slight flexion and lateral flexion

ROM decreased globally and segmentally with many joint levels often locked up

Typically increased pain with flexion and lateral flexion toward involved side

Muscle spasm and tenderness with no point tenderness over facets

NORMAL SMRs

47
Q

How would you manage a pt with acute locked low back?

A

Close the pain gate and control inflammation. Stop the pain-spasm cycle via cryotherapy (cold therapy) and electro therapy. Analgesics or short term anti-inflammatory meds may help

CMT: gap the joint to release entrapped meniscoid

STM: reduce muscle spasm

48
Q

What is spinal canal stenosis?

A

Degenerative condition resulting in decreased cross sectional area of the spinal cord.

More common in pts 60-70+yo
14% of pts with LBP will have stenosis

49
Q

Radiographic stenosis vs clinical stenosis

A

Radiographic stenosis: Symmetrical disc bulging, facet enlargement, thickened ligamentum flavor

Clinical stenosis: neurogenic claudication, radicular syndrome or both

50
Q

What is the history with a pt with spinal canal stenosis

A

> 65 yo with unilateral or bilateral LE sx

Findings:

  • No pain when sitting +LR 7.4
  • CES Sx +LR 7.2
  • Unexplained urinary problems
  • Flexion improves sx +LR 6.2
  • Bilateral but or leg pain +LR 6.3
  • Neurogenic claudication (non dermatomal pain) +LR 3.7

Diagnostic prediction tool can be used to confirm. Score >7 has a +LR of 3.31 for clinical stenosis

51
Q

What is a physical exam findings for a pt with spinal canal stenosis

A
  • wide based cate +LR 13
  • abnormal Romberg test +LR 4.2

Pertinent negative
- provocation of pain with forward flexion -LR 0.48

Additional clues may increase the likelihood of clinical stenosis

  • LE weakness
  • absent Achilles reflex
  • loss of vibration sense in the LE
  • loss of pinprick in LE
  • sustained extension increases pain
52
Q

What is a pertinent negative for spinal canal stenosis? And what is the LR?

A

Provocation of pain with forward flexion

-LR 0.48

53
Q

What special studies would you run on a pt with suspected spinal canal stenosis?

A

Plain film radiographs
CT/MRI if suspicious remains high after xray

Rule out peripheral arterial disease:
US or MRA

54
Q

How would you manage a pt with spinal canal stenosis?

A

CMT: Normalize joint fxn with mobilization, manipulation, flexion-distraction.

STM: MFTP therapy.

BM: modify standing posture to have 1 foot elevated or lean over the desk, practice posterior pelvic tilt.

Exercise: Rehab program with stabilization exercises, walking program, double knee to chest exercises that promote lumbar flexion.

If conservative care is not effective, surgery is an option:

  • epidural injections
  • surgical decompression
55
Q

What is the prognosis for spinal canal stenosis?

A

10-12 weeks
Improvement should be seen in 3-4 weeks and maint or exceeded by the week 6.

Pt should be monitored for signs of CES (6% chance).

Motor and sensory fxn should be monitored, if sig deficit occurs they should be referred out for surgery.

56
Q

What could a walking program for someone with spinal canal stenosis be like?

A

First week, start walking every day or doing some kind of aerobic activity. Eventually get to 20-60 minutes each day. Later, walking on uneven, sloping, sandy/moving ground.

Proprioception: wear a low back pack with 22 lbs.

57
Q

What is lumbar sprain? Lumbar strain?

A

Sprain: painful injury of lumbar ligaments

Strain: painful traumatic tear of large posterior muscles of the back

Sprain/strain combined are associated with higher loads or higher reps aka “lumbalgia”

58
Q

Most common lumbar sprains?

A

Supraspinous

Interspinous

59
Q

Most common lumbar strains?

A

QL

Erector spinae

60
Q

What is a common history for pts with lumbar sPrain?

A

Pain midline to unilateral with or without referral to buttocks/extremity

History of trauma or overuse

History does not support vectors that could injure large back muscles

61
Q

What is a common history for pts with lumbar sTrain?

A

Dull, achy back pain commonly bilateral, referral to the legs is uncommon.

Initiated by trauma.

62
Q

What is a common physical exam for pts with lumbar sPrain?

A

Guarded posture neutral to slightly flexed

AROM protective and restricted

PROM in the direction of injury or loading is painful

Palpation

  • pain over joint
  • pain with joint play
  • focal muscle splinting
  • end play not reached due to guarding
  • isometric muscle contraction is pain free, or less painful
  • repetitive loading does NOT centralize pain

**if pain is more clearly aggravated by RESISTED MM TESTING, think sTrain (not sprain).

63
Q

What is a common physical exam for pts with lumbar sTrain?

A

Guarded posture, superficial bruising may be present

AROM protective and restricted

Palpation

  • broad palpable mm tenderness and hypertonicity at iliac crest (enthuses)
  • localized defect and swelling (uncommon)
  • no or minimal pain with joint play
  • pain provoked by lumbar flexion and especially resisted lumbar extension test

**if pain is more clearly aggravated by RESISTED MM TESTING, think sTrain (not sprain).

64
Q

What are special studies you’d run for a lumbar sPrain?

A

Trauma: X-ray to rule out fracture

Flexion-extension dynamic x-ray to rule out instability or poor response to Tx

65
Q

What are special studies you’d run for a lumbar sTrain?

A

MSK US (rarely needed)

66
Q

How would you manage a pt with lumbar sPrain/sTrain?

A

CMT & STM:

  • ACUTE: light massage, joint mobilization
  • SUBACUTE: manipulation, PIR/CRAC/pin and stretch, IASTM

Exercise:

  • ACUTE: light stretching, muscle relaxation exercises (PIR)
  • SUBACUTE: strengthening, lumbar stab, core stab, endurance

In the acute phase, limit end range flexion, lifting, or activities requiring full ROM until pain free.

Other: ice, heat, electromodalities, shorter term use of lumbosacral corset

67
Q

Prognosis for lumbar sprain/strain

A

Mild cases resolve in a couple days, more severe may take 2+ weeks with low level pain up to 6 weeks.

68
Q

What is spondylolysis?

A

Unilateral or bilateral stress fracture of the bridge between upper and lower pars interarticularis. It can range from a defect in the pars to a full Fx with separation. Bilateral in 80% of symptomatic cases, most commonly at L5 and then L4.

Estimated prevalence 6-13% of general population. Often asymptomatic.

In young athlete, prevalence rises to 47% of LBP. M>F 2:1

69
Q

What is a common history of spondylolysis?

A

Suspect in a teenager or young adult with LBP, especially if they are an athlete in sports requiring:

  • repeated flexion and extension
  • repeated hyperextension
  • twisting and axial load activities

Gymnastics and footballs are the highest risk sports
75% of cases in athletes <20 yo that train >15 hours per week

Pain onset may be sudden (50%) or gradual, acute then dull and achy in chronic presentation. Difficulty falling asleep, pain worse with sitting and standing (75%).

Pain associated with hyperextension is a common finding. (Increased lordosis is provocative.)

70
Q

What physical exam findings would you expect with a spondylolysis?

A

AROM is variable — normal to reduced, pain elicited with extending from a flexed position, rotation/lateral flexion to the side of lysis, or hyperextension. Flexion may be pain relieving. Psoas may be short and tight bilaterally.

Stork test — poor accuracy, but increases likelihood of bilateral fracture if positive on both sides.

In acute cases — focal tenderness over the lumbar spine and discomfort with deep palpation.

No neurological deficits (though may occur if the Fx is filled with fibrocartilage as it heals that may impinge NRs).

71
Q

Special studies for spondylolysis?

A

Radiographs, though often inconclusive in early stages.

  1. AP & Lateral
  2. AP axial lumbosacral spot view and/or oblique view

MRI, CT, SPECT Scan can be done

  • CT cannot differentiate between active and non-active fx
  • SPECT is the gold standard and can differentiate between active and inactive fx, but has substantial false positives, high radiation, and cannot rule out facet arthritis, neoplasm, or infection that are also active
  • MRI is as accurate as CT but with no radiation dose. This should be ordered in rare cases that present with neurological signs
72
Q

What is the management and prognosis for spondylolysis?

A

Primary goal is to prevent slippage, conservative care is effective in 95% of cases

Pt should avoid sports or activities that require repetitive flexion and extension. Pt must stop the activity or sport that evokes pain for 2-4 weeks, if symptoms do not resolve refraining from activity may be required for 3-6 months

Bracing to immobilize the pelvis and prevent hyperextension may be required. Worn 20-23 hours per day for 3-6 months and then slowly weaned off.

Acute intervention - ice 20 minutes, 3-4x per day, pain free ROM, stretch hip flexors, hamstrings, and psoas
Rehabilitation should focus on stabilizing the low back and core.

Stopping sports activity >3 months is reported to have better outcomes.
