Sacral base unleveling
Often associated with scoliosis
Iliolumbar ligament is typically first structure to react to added stresss in lumbosacral area

Q

What are some treatment considerations a for short leg syndrome

A

Treat SD area first
Exercise for stretching asymmetric muscles
Heel lift therapy
Acute change in leg length = replace full discrepancy immediately *

Q

Heel lift therapy

A

For short leg syndrome
Typically only treated if leg length discrepancy is greater than 5 mm
Max 1/4 Heel lift in shoe, 1/4 may be added to outside for total 1/2
May add the full 1/2 outside of shoe
Final life height should be 1/2 to 3/4 of measured discrepancy unless recent sudden cause apparent

Q

What are some PE associated with spondylolysis / spondylolisthesis ?

A

Children - usually asymptomatic
Adolescent athlete typically has gradual onset of symptoms in acute / subacute spondylolysis, worse when participating in activities
Pain may radiate to buttocks or posterior thigh - more common in spondylolisthesis

18
Q

What are the common SD assocIated with spondylolysis and spondylolisthesis?

A 
Psoas spasm or inhibition 
Iliacus dysfunction 
Flexed upper lumbar dysfunction 
Sacroiliac / sacral torsion dysfunction 
Innominate dysfunction
19
Q

Treatments for spondylolysis and spondylolisthesis

A

OMT mostly indirect or ST
NO HVLA

Exercise focus on strengthening muscles and diminishing lordosis
Hamstring stretch
Postural improvement techniques
Avoid contact sports
Orthotics, braces, casts
Anti-inflammatory medication, muscle relaxants have limited role
Potential indications for surgery ie. progressive slippage, Neuro deficits, segmental instability with pain

20
Q

Patient c/o pin right buttock radiates down posterior thigh for 1 week. No weka was in right leg, but lost balance a few times. Straight leg test is positive. Imagine shows lumbar spine herniation of spinal disc b/w L4 and L5. Protrusion of which anatomical structures is most likely causing patients sx?

A

Nucleus pulposus

21
Q

What is the most common type of spinal disc herniation?

A

Posterolateral herniation

22
Q

What are some PE findings / sx associated with spinal disc herniation?

A

—Sudden onset of LBP with bending or lifting or more gradual onset

  • Most sx are caused by inflammation of nerve root, not by direct compression
  • Radiculopathy
  • straight leg positive
23
Q

What disc are most commonly affected in spinal disc herniation?

A

L4-L5 and L5-S1

24
Q

What are some causes of spinal disc herniation?

A
  • microtrauma from rotational stresses predisposes the disc to damage
  • sudden compressive or rotational force can cause tear in weakened nucleus pulposis
25
Q

Treatment for spinal disc herniation

A

Most patients treat conservatively for acute sx ie rest a few days, ice , NSAIDs, steroids

Once acute phase has subsided consider OMT Targeted musculature and physical therapy

FPR technique useful if sx of radiculopathy

Indications for sx - intractable pain, progressive, or moderate to severe Neuro deficit

26
Q

Diagnosis for spinal disc herniation

A

Clinical test of choice is MRI for confirmation

27
Q

Patient pr3ents to ED for LBP radiates down her bilateral posterior thighs to level of the knee. Started 13 hours ago when she was helping move a couch and something “ tweaked wrong” in her back. She has not urinated or had a bowl movement t since this event. What is most likely to be found on PE?

A

Decreased pinprick sensation in perineum

Cauda equina syndrome

28
Q

What some sx and PE findings for cauda equina syndrome?

A
  • radicular pain
    -paresthesia
    -sensory loss in distribution of nerve roots
    -bilateral lower extremity pain
    -results in bowel or bladder dysfunction
    -sensory loss of perineum (saddle anesthesia), decreased anal sphincter tone
    MEDICAL EMERGENCY
29
Q

What is the cause of cauda equina syndrome and txt ?

A

Spinal nerve root compression usually by a massive disk protrusion, fracture, or abnormal mass
Txt as MEDICAL EMERGENCY
Emergent management and surgical decompression within 48 hours or risk permanent neurological damage

30
Q

Degenerative disc disease

A

Natural part of aging
By 49, 60% of women and. 80% of me have osteophytes and other changes indicative of degeneration
- lumbar spine particularly affected due to mobility and weight bearing responsibilities
-poor correlation with X-ray findings and degree of pain
-txt with OMT, PT, acetaminophen/NSAIDs

31
Q

Spinal stenosis and causes

A 
- narrowing of spinal canal 
Causes
- herniated our bulging intervertebral disc 
- abnormal mass
- osteophytes 
- scar tissue from previous surgery
32
Q

Central vs lateral spinal stenosis

A

Central may result in neurogenic Claudication

33
Q

Sx of spinal stenosis

A

Back pain frequently associated with radiculopathy

Pain exacerbated by standing and walking, relieved by sitting or lying down

34
Q

Spinal stenosis diagnosis and txt

A

MRI
OMT offered relief of sx in 50% of patients
PT and aspirin / NSAIDs
Severe casa require surgery

35
Q

Contraindications for OMT in LBP

A
  • No HVLA vertebral tumor or cancer metastasis to spine ( can do other techniques as long as directly involved site is avoided)
  • no HVLA Hx of osteoporosis
  • no HVLA Acute lumbar disc herniation - relative contraindication
  • Most types of direct txts for compression fx contraindicated except direct MFR
  • no HVLA in acute phase rheumatiod arthritis affecting lumbar spine
36
Q

Spinal curve compensation in aging?

A

Kyphosis

37
Q

Spinal curve compensation in pregnancy?

A

Increased kyphosis and lordosis

38
Q

Psoas strain causes what type of spinal curve compensation?

A

Loss of lordosis

39
Q

What is compensated zink pattern?

A

L/R/L/R common

R/L/R /L uncommon

40
Q

What is uncompensated zink pattern?

A

R/R/L/ L and others
