Positive leg roll with sciatic notch tenderness

Unlike sciatica from disk herniation piriformis syndrome is exacerbated by active external hip rotation*

62
Q

A narrowing of the spaces within your spine which can put pressure on the nerves that travel through the spine
Occurs most often in the lower back and neck

63
Q

Neurogenic claudication describes what?

A

Arthralgia or polyarthralgia
Arthritis, reactive arthritis and psoriatic arthritis
Ankylosing spondylitis

72
Q

What is arthritis?

A

A diagnosis and not a sx

Diagnosis requires the physical signs of articular inflammation or the physical or X ray signs of OA

73
Q

What is ankylosing spondylitis?

A

MC form of spodyloarthropathy
Related to the prevalence of HLA-B27
Most often affects white males between 15-40 years of age
Bamboo spine will be seen on an X-ray of the lumbar spine

74
Q

What is reactive arthritis?

A

Often develops after an infection in the urinary tract or GI system
More common in males
Related to Reiter’s syndrome (eye, urethra and joint inflammation)

75
Q

What is psoriatic arthritis?

A

Affects major joints of the body and is typically asymmetric
Usually happens to people with a skin condition called psoriasis
Nail pitting is usually seen

76
Q

Describe malignancy (cancer)

A

Risks include age, FHx, smoking and cancers that metastasize to bone
Presentation includes pain that worsens in the prone position, recent weight loss and fatigue
Upon exam typically have spinous process tenderness with metastasis to the spine

77
Q

What is vertebral diskitis/osteomyelitis?

A

Inflammation that develops between the IV discs of your spine
Major risk includes IV drug abuse
Presents with severe back pain with or without fever
Upon exam there will be constant pain, spinous process tenderness and often no fever
