HIP/SI Joint Pathology

Question 1

What is an acetabulum labrum?

Answer 1

Ring of cartilage that surrounds the acebulum
Anterior portion most vulnerable to tears
Allows head of femur to articulate with the pelvis

Question 2

What is osteoarthritis of hip

Answer 2

Deteriorating cartilage= rubbing bone= possible bone spurs

Risk= age, family history, injury, history

Question 3

Osteoarthritis Sx

Answer 3

Anterior groin pain, pain worse with time, worse with activity, stiffness= difficulty walking/bending, locking joint, crepitus, worse with rainy weather

Question 4

How can you distinguish hip pain with SI/lumbar issues?

Answer 4

Hip is anterior
SI/lumbar is posterior
(Patients often point posterior and say they complain of hip pain)

Question 5

What is Ankylosing Spondylitis

Answer 5

• Systemic rheumatic dz, chronic inflammatory dz of axial skeleton
• spine starts fusing at SI joint-> cranial
• Unknown cause
• genetic

Question 6

Sx of Ankylosing spondylitis

Answer 6

• gradual onset, peak around 20-30 yrs
• initial chronic dull achy back/glute stiffness
• AM stiffness, worse with rest, better with movement
• Systemic Sx= weight loss, fever, fatigue
• eye pain
• inflammation of the prostate
• cardiovascular/LU involvement

Question 7

SX of sacroiliac dysfunction

Answer 7

• dull unilateral low back pain, isolated around PSIS
• pain stiffness worse prolonged sitting/walking
• inability to roll off back once supine
• severe= referred pain into hip/groin/low leg (rarely below knee)

Question 8

Hyper mobility SI

Answer 8

• very uncommon
• maternity
• joint not fully developed until mid twenties, most occurance a happen prior to this age

Question 9

Hypo mobility SI (4) kinds/causes

Answer 9

1) up slip= fall on buttocks
2) down slip= forced pull on leg (less common)
3) anterior rotation= tight hip flexor a, increased lumbar lordosis, high heels
4) posterior rotation= tight hamstrings, decreased lumbar lordosis

Question 10

What is hip dysphasia

Answer 10

Abnormal congenital formation of acetabulum

Sx= asymmetric gluteal folds, limb length inequality, pigeon toed/w-sit

Question 11

What are the common causes of hip dysplasia

Answer 11

1) congenital- hormonal (relaxin), females, genetic (indigenous)
2) aquired- swaddling infants with legs together, breech birth

Question 12

What is it called when both ilium are rotated anteriorly

Answer 12

Out flare

Question 13

What is it called when both ilium are rotated posteriorly

Answer 13

Inflare

Question 14

What is an acetabulum Labrador tear

Answer 14

• cause= high impact, SHI ROM at hip
• Sx= asymptomatic, pain in groin, clicking in socket with movement, stiffness, decrease ROM hip
• risks= reg. Hip rotation (golf, ballet), high impact, osteoarthritis
• *75% insidious
