WHEN DO WE OPERATE?

•SURGERY IS THE LAST RESORT

• Good spine surgeons exhaust all other necessary options

• The act of operating is wrought with risks

• Want to be sure to have good outcomes, the indications and outcome shouldn’t

be the risk laden part

• Must have right indications for operating

ADVANCEMENTS IN TREATMENT

• Herniated discs → if fail conservative pain management,

have minimally invasive outpatient procedures to perform

microdiscectomies

• Axial back pain → If fail conservative pain

management, we have minimally invasive techniques for

facet arthropathy and degenerative disc disease including

disc replacement and not fusion.

• Debilitating compression fractures → if fail conservative

management have MIS outpatient kyphoplasty treatments

• SI joint pain → If fail conservative management. Have

outpatient MIS treatments.

PROBLEMS THAT WE HAVEN’T RESOLVED

• Adjacent level disease

• How do you stress shield the disc above or below

a treated spinal level, so it does not fail sooner?

• Medical treatment for the prevention of

degenerative spine changes

• Restorative treatments for degenerative

spine changes

Page 8: Spine Surgery: Where we ARE todaynevadaosteopathic.org/attachments/article/61/18.Spine Surgery.pdf · WHEN DO WE OPERATE? •SURGERY IS THE LAST RESORT •Good spine surgeons exhaust

ALGORITHM OF TREATMENT

• Common algorithm of spine related conditions

• Neck/back or extremity pain → active treatment by the patient (OTC pain

meds, patches, creams) → Resolved

• See family/primary care provider → Treat conservatively (OMT, Pain meds)

→ Resolved

• Imaging (XR, CT, MRI)→ Continue non-operative management or Pain

management → Spine surgeon

COMMON AILMENTS AND TODAYS SURGICAL TREATMENTS

• Radiculopathy

• Neurogenic Claudication

• Axial Back Pain

• Compression Fractures

• SI Joint pain

RADICULOPATHY/ SCIATICA /HERNIATED DISC

• Usually from nerve root compression

• Can be from disc herniation or foraminal stenosis

• Dermatomal in nature

• Usually dermatomal sharp shooting pain in acute phase.

• Can be dull achy pain usually in chronic phase

Page 12: Spine Surgery: Where we ARE todaynevadaosteopathic.org/attachments/article/61/18.Spine Surgery.pdf · WHEN DO WE OPERATE? •SURGERY IS THE LAST RESORT •Good spine surgeons exhaust

• Classically a paracentral disk herniation

• Can also be from foraminal collapse, facet joint overgrowth, or a far lateral

disk herniation

• Diagnostic testing would include MRI, CT scan (looking for osseous pathology),

or a CT myelogram if can’t have an MRI

NEUROGENIC CLAUDICATION/LUMBAR STENOSIS

• Unilateral or bilateral leg pain, numbness, or weakness usually while standing

or walking

• Physical exam can be normal

• Usually symptom improvement with flexion of spine

• Distinguish from vascular claudication

• Improve with rest and not flexing forward.

Page 19: Spine Surgery: Where we ARE todaynevadaosteopathic.org/attachments/article/61/18.Spine Surgery.pdf · WHEN DO WE OPERATE? •SURGERY IS THE LAST RESORT •Good spine surgeons exhaust

WORK-UP

• MRI, CT, myelogram

• Can be caused by:

• congenital canal stenosis

• Disk bulge

• Ligamentum flavum hypertrophy

• Facet joint overgrowth

• spondylolisthesis

Page 20: Spine Surgery: Where we ARE todaynevadaosteopathic.org/attachments/article/61/18.Spine Surgery.pdf · WHEN DO WE OPERATE? •SURGERY IS THE LAST RESORT •Good spine surgeons exhaust

TREATMENT

• Conservative treatment:

• OMT

• Epidural injections

• Physical therapy

Page 21: Spine Surgery: Where we ARE todaynevadaosteopathic.org/attachments/article/61/18.Spine Surgery.pdf · WHEN DO WE OPERATE? •SURGERY IS THE LAST RESORT •Good spine surgeons exhaust

SURGICAL THERAPY

• Standard therapy involves a midline laminectomy and foraminotomy

• New therapies include indirect decompression with an interspinous spacer

device, causes focal flexion and stretching of the ligamentum flavum and facet

joint

• I recommend with caution - The focal flexion can cause other issues including DDD, and

kyphosis with loss of sagittal balance

• Minimally invasive hemilaminectomy with bilateral ligamentum flavum resection

and decompression

AXIAL BACK PAIN (DEGENERATIVE DISEASE)

• Pain that worsens with activity and lessens

with rest.

• Anterior thigh pain can be associated with

low back pathology due to somatotopic

pattern

NEUROIMAGING

• Develop black disc due to loss of disc water content

• Loss of disc height

• Modic end plate changes (high T2 signal) in the sandwiching boney endplates

TREATMENT

• Conservative Treatments:

• OMT

• Physical therapy – core strengthening exercises

• ESI

• Surgery if all else fails

Page 32: Spine Surgery: Where we ARE todaynevadaosteopathic.org/attachments/article/61/18.Spine Surgery.pdf · WHEN DO WE OPERATE? •SURGERY IS THE LAST RESORT •Good spine surgeons exhaust

SURGERY

• Theory of surgical intervention rests on notion that movement and motion of

that spinal segment causes pain.

• Aims to eliminate motion in that disc level known as fusion.

• Many ways to perform

Page 33: Spine Surgery: Where we ARE todaynevadaosteopathic.org/attachments/article/61/18.Spine Surgery.pdf · WHEN DO WE OPERATE? •SURGERY IS THE LAST RESORT •Good spine surgeons exhaust

APPROACHES TO THE SPINE

• ALIF - Good for restoring

height and lordosis

• OLIF – Less risk of vascular

injury, restore height

• XLIF– less risk of vascular

injury, restore disk height

• PLIF- single stage/position

surgery, address posterior

pathology

• TLIF– single stage/position

surgery, address posterior

pathology, less retraction

than PLIF

COMPRESSION FRACTURES

• Can be pathological or traumatic or insufficiency

• Common in aging population

• Pathologic usually from tumor – Find source (Primary vs. Mets)

• Treatment is decompressive spine surgery if necessary or radiofrequency ablation and

cement kyphoplasty along with systemic treatments of chemo and radiation

• Traumatic or insufficiency fracture – Treat with conservative pain management

and bracing

Page 39: Spine Surgery: Where we ARE todaynevadaosteopathic.org/attachments/article/61/18.Spine Surgery.pdf · WHEN DO WE OPERATE? •SURGERY IS THE LAST RESORT •Good spine surgeons exhaust

WORK UP

• Imaging to determine acuity of fracture

• Percutaneous Vertebral Augmentation (kyphoplasty) good option in acute and

subacute fractures

• Best indicator of acuity is MRI → Hypointense T1, Hyperintense T2 and

positive STIR.

• Can have 80-90% improvement in pain.

PERCUTANEOUS VERTEBRAL AUGMENTATION (KYPHOPLASTY)

• Can be performed outpatient

• Can be performed with general anesthesia, light sedation or local anesthesia

• Objective is pain relief and stabilization

• Increased activity level and decreased dependence on opioids.

SACROILIAC (SI) JOINT PAIN

• 15-20% of axial low back pain patients have SI joint pathology.

• Characterized by upper buttock pain just below the level of the posterior

superior iliac spine (PSIS), especially with positional changes.

• From siting going to standing.

• Climbing or descending stairs

• Single-leg stance

• Provocative tests can be performed

Page 44: Spine Surgery: Where we ARE todaynevadaosteopathic.org/attachments/article/61/18.Spine Surgery.pdf · WHEN DO WE OPERATE? •SURGERY IS THE LAST RESORT •Good spine surgeons exhaust

SI JOINT PROVOCATIVE TESTS

• FABER = Flexion,

Abduction, External

Rotation

• 2 - 3 positive tests

indicative of SI Joint

Pain→ OMT and

physical therapy

+/- SI Joint

injection/block

Page 45: Spine Surgery: Where we ARE todaynevadaosteopathic.org/attachments/article/61/18.Spine Surgery.pdf · WHEN DO WE OPERATE? •SURGERY IS THE LAST RESORT •Good spine surgeons exhaust

SI JOINT TREATMENT

• If conservative management including OMT,

SI Joint strengthening exercises fail and the

patient has at least 70% relief from two

separate SI Joint blocks then they are a good

candidate for SI Joint Fusion
