Hip Intro Flashcards
What is the typical age range for developmental hip dysplasia, transient synovitis and legg-calve-perthes disease
Developmental hip dysplasia- 0-4
Transient synovitis- 2-10
Legg-calve-perthes- 2-8
What is the typical age range for Slipped capital femoral epiphysis, femoral neck stress fx, snapping hop
Slipped capital femoral- 10-14
femoral neck fx- 14-30
Snappin hip-20-40
What does the iliofemoral lig resist
Strong ant- resists hyperextension
What does the pubofemoral lig resist
Reinforces hip capsul inf, resists hyperabduction
What does the ishiofemoral lig resist
Reinforces hip capsul post- resists hyperextension + applies medial compressive force
relative bw force in: erect posture, supine SLR, stance phase, running, stair climbin
erect- 0.5bw supine SLR- 1.5bw Stance phase- 2.5-4bw running- 4.5-5bw stair climbing- 6bw
What are red flags related to the hip (8)
Rheumatologic conditions Infections Tumours Stress fractures Epiphyseal joint fractures Joint pathology: AVN, LCP, SCFE (discussed later) Congenital Dysplasia of the Hip Abdominal Aortic Aneurysm (AAA
What % of individuals in imaging have hip abnormalities present
> 70% of hips display abnormalities
What is the potential mechanism of hip relation to back pain (5)
- reduced hip motion
- +/- capsular stiffness
- altered loading
- Tissue stress/sensitization
- LBP
What 3 symptoms related to the hip are most associated with cronic low back pain (2)
- hip jt pain
2. morning stiffness + pain w/ hip int rot
what is hip/spine syndrome
in elderly patients this refers to coexisting degenerative changes in the hip and spine (high correlation between the 2)
LBP is a poor prognositic factor for pts with
Hip OA (but not knee OA)
when should you assess the hip (3)
- local hip complaints
- Mechanical low back pain/pevic/si
- lnee pathology
