Q

What is femoral anteversion?

A

increased angle of torsion (angle between femoral head/neck and an axis through the distal femoral condyles)
- “pigeon toed”
- heel strike with pronated foot –> forefoot varus compensation

Q

What is femoral retroversion

A
  • decreased angle of torsion
  • toes out

What is trochanteric bursitis
- inflammation of deep tronchanteric bursa from a direct blow, irritation by/tight ITB, poor posture/biomechanics causing repetitive micro trauma, weak glute med
26
Trochanteric bursitis clinical presentation
- pain complains to lateral hip --> point to specific spot - local tenderness over greater trochanter - may have pain with resisted abduction - symptoms increase with walking, stair climbing, laying on effects side, and crossing legs
27
trochanteric bursitis intervention
- pt education on activity modification and positioning for relief - stretch tight structures causing postural deviations or asymmetries - strengthening weak muscles causing instability or faulty movement patterns
28
trochanteric bursitis is common in pts with..
RA
29
Psoas bursitis clinical presentation
- pain anterior hip or thigh - aggravated by excessive hip flex - can be related to OA or iliopsoas muscle tightness
30
Ischial bursitis clinical presentation
- pain in buttock/posterior thigh - aggravated by stairs/incline walking (when hip is flexed and extensors are contracted) - avoidance of sitting on affected hip
31
diagnostic test for bursitis
- none - diagnosis made by clinical examination
32
What two tests may be positive for ITB tightness
- noble compression test - Ober's test
33
What does Craig's test measure
- femoral anteversion and retroversion
34
Different angles of piriformis
- ER of hip at < 60 degrees hip flex - IR of hip at > 90 degrees hip flex
35
tightness, straining, or spasm of the piriformis can result in
compression of sciatic nerve and/or sacroiliac dysfunction
36
signs and symptoms of piriformis syndrome
- pain worse with sitting, stair climbing, crossing leg - restriction in IR - pain with palpation to piriformis - referral of pain to post thigh - weakness in ER - + piriformis test
37
What should you rule out when looking at piriformis syndrome
involvement of lumbar spine and/or SI dysfunction
38
Pt goals for piriformis syndrome
- treat strain or improve length of tight muscle - correct biomechanical asymmetries - pain reduction - functional training and resistance training
39
Etiology of acetabular labral tears
- FAI - dysplasia (acetabulum is too small for femoral head) - capsular laxity and degeneration - direct trauma - sports injury --> frequent ER of hip, sprinting - can occur with hyperextension, hyperextension with ER, or hyperabduction - 74% not associated with any specific event or cause; may be secondary to micro trauma
40
FAI - CAM type
impingement of a large aspherical femoral head in a constrained acetabulum
41
FAI - pincer type
- over-coverage of the femoral head by a prominent acetabular rim
42
Clinical presentation of acetabular labral tears
- F>M - anterior hip/groin pain - clicking, catching, "sharp", "giving out" - decreased ROM (most commonly decreased rotation) - may have + FABER - difficult to diagnose
43
what is the gold standard diagnostic test for acetabular labral tears
arthroscopy
44
Hip arthroscopy for labral tear - rehab considerations
- brace 2-6 weeks - NWB or Foot flat WB 2-8 weeks - rehab can start POD 1-2; some surgeons wait - continuous ROM - 4 hrs - prone laying to reduce tightness of iliopsoas
45
What is a sports hernia
- tear of oblique aponeurosis --> thought to be stronger pull of adductors on pelvis vs oblique mm
46
sports hernia is common in...
sports requiring kicking, rapid acceleration/deceleration and sudden change of direction (hockey, soccer, etc)
47
sports hernia may be related to pathology in
- adductor - iliopsoas - inguinal - pubis
48
what should you rule out in sports hernia
hip involvement
49
length of rehab period for sports hernia
- 8-12 weeks - may come back with activity - surgery if conservative methods fail
50
Slipped capital femoral epiphysis
- posterior and inferior slippage of the femoral epiphysis on the femoral neck - occurs in early adolescent with growth spurt - common initial complain is hip and/or knee pain
51
Legg Calve-Perthes Disease
- idiopathic osteonecrosis of the epiphysis of the femoral head - 5x > in M - 3-12 yo - hip or groin pain, limp, decreased ROM in IR and ABD - work to restore ROM
52
What is Coxa Saltans
- snapping or clicking hip
53
intra-articular causes of Coxa Saltans
- loose bodies - subluxation of hip
54
Extra articular causes of Coxa Saltans
- ITB over greater troch - iliopsoas tension over labrum and femoral head (AKA iliopsoas impingement --> work on lengthening iliopsoas) - iliofemoral ligament over femoral head - biceps femoris over ischial tuberosity
55
Hip resurfacing candidates
- male; < 60 yo - normal functioning kidneys - active lifestyle - BMI < 30
56
Anterolateral THA
- anterior 1/3 of glute med and min released and repaired - no hip flex > 90 - no hip ext, abd, ER past neutral
57
Posterolateral THA
- short ERs and pirifomis released and repaired (glute med intact) - no hip flex > 90 - no IR, add past neutral
58
hip convex/concave rule
convex moving on concave
59
hip OPP/CPP
OPP: 30 degrees flexion, 30 degrees abduction, slight lat rotation CPP: full extension, abduction, internal rotation
60
hip capsular pattern
flex > IR > abd

flex: 110-120 ext: 10-15
