Sacroiliac Joint Sprain

Question 1

SI joint hypomobility

Answer 1

usually occur in younger people
associated w lumbar or pelvic rotational stress
can develop after pregnancy or trauma
associated w innominate rotational dysfunctions
can be incidious (proceeding in gradual way but harmful)

Question 2

SI joint hypermobility

Answer 2

can be secondary to instability of pubis symphysis
can be associated w Osteitis Condensans
can occur in younger women soon after pregnancy as ligaments remain lax for 6-12 weeks
symphysis can become a truly mobile joint resulting in pelvic instability

Question 3

symptoms

Answer 3

SI joint pain
dull ache refering to low back and glutes
iliopsoas tenderness
pain increases w position changes
using stairs, sitting to standing, turning over in bed
pain may increase w prolonged postures
possible sacral edema
mm spasm/HT/TRP in glutes, low back, ilopsoas
pelvic dysfunction

Question 4

grade 3 sprain

Answer 4

complete rupture leading to instability
can lead to hypo or hypermobility lesions
very rare

Question 5

contributing factors

Answer 5

congenital hypermobility
hx of SI joint sprains
altered biomechanics
leg length discrepancy
connective tissue pathologies
RA
rotational stress
pregnancy

Question 6

observations

Answer 6

pain moving from sitting to standing (vise versa)
antalgic gait if sprain is severe

Question 7

palpation tenderness
