New cards
59

25-35 degrees

What is a normal lumbosacral/Ferguson’s angle?

Possible other causes: Appendicitis, Ureter Dysfunction, Sigmoid Colon Dysfunction, Ureteral Calculi, Salpingitis, Metastasis of Prostate CA. Presents with low back pain, some patients may have pain radiating to groin. Increase pain with standing, walking. May have contralateral piriformis spasm. Pain quality described as ache or spasm. Often associated with flexion/extension dysfunction of L1 or L2.

New cards
64

Herniated Nucleus Pulposus

Due to posterior lateral herniation of intervertebral disc near narrowing of posterior longitudinal ligament exerting pressure on nerve root. 98% at L4 and L5.

Weakness & Decreased Reflexes from affected nerve root, sensory deficit to affected dermatome.

New cards
65

Annulus fibrosis

New cards
66

Spinal stenosis

Narrowing of the spinal canal or intervertebral foramina, causing pressure on nerve roots. Usually secondary to degenerative changes. Degenerative changes can include: Facet joint hypertrophy, Calcium deposits of ligamentum flavum, Calcium deposits of posterior longitudinal ligament, Intervertebral disc height loss. Patient presents with lower back pain that radiates to lower extremities, worse with exertion.

Fracture of pars interarticularis appears as a “collar on neck of a scotty dog”  

New cards
70

pelvic stability

Nutation = ???

This increased compression creates increased friction between the sacrum and the innominate. This combination of compression and increased friction creates a force closure tat allows the SIJ to effectively transfer loads between the trunk, pelvic, and lower extremities
