Lower Extremity: Hip/ Pelvis

QuestionAnswer
ROM for climbing stairs ~70° (1° ext to 60+° flex)
ROM for sit to stand Depends on height of seat: 112° avg. flex
ROM for squats 115° flex
ROM for stooping 125° flex
ROM ideal for most ADL's 120° flex, 20° abd, 20° ER, 10° hyperext
Functional ROM (Gait) -Maximally flexed to 30º at heel strike and a moving into extension for foot flat -Maximally hyper-extended to 10º at heel off
Referred P! Primarily from cutaneous nerve innervation -From SI jt. to glutes, lateral hip, groin -From hip jt. to anterior thigh, possibly knee
Radicular P! from T12-L2 and S1-3 spinal nerves
Lumbopelvic Rhythm -Motion between spine, pelvis, hip -Allows greater ROM -Similar to shld. complex
Hip flexion is accompanied by _____ mm contraction abdominal
Hip extension is accompanied by _____ mm contraction spinal extensor
Hip flexor tightness/ weak trunk flexors cause -Anterior pelvic tilt -Increase lordosis -Knee position may be altered
Tight hip extensors/ hamstrings -Posterior pelvic tile -Decreased lordosis
Hip ER weakness is a predictor of LE injury
Non-arthritic hip joint P! -Femoral acetabular impingement (FAI) -Instability -Labral tears -Chondral lesions Ligamentous teres tears
Osteoarthritis (OA) -Most common cause of hip P!
Femoral acetabular impingement (FAI) risk factors -Genetics -Males>females -Higher activities involving more end range hip motions and higher forces (i.e gymnastics)
OA risk factors -Older age -Previous joint injury -Increasing BMI (overweight/obese) -Occupational activity i.e. deep squats or stairs with or without loads -NOT exposure to sport or physical activity which actually may be protective
FAI Etiology -Genetics- 2-2.8x relative risk for a sibling -Slipped Upper Femoral Epiphysis (SUFE) -Femoral neck fx and/or malunion -Perthes’ Disease- avascular necrosis -Western > Eastern world -3 congenital types
Femoral acetabular impingement (FAI) 3 types: FAI-Cam FAI-Pincer FAI-Mixed
FAI-Cam -Decreased anterior or superior femoral head neck offset (larger femoral head -Head contacts anterosuperior acetabulum -Higher risk of articular cartilage lesion -Twice as common in males vs. females
FAI-Pincer -Acetabular retroversion or coxa profunda (deeper acetabulum) or anterior osteophyte -Neck primarily contacts anterior but possibly posterior labrum (countercoup phenomenon) -Most common in middle aged athletic females
FAI-Mixed Most common
OA Etiology -See tissue healing notes -LBP predicted subsequent OA-related p! and disability in those with hip disease
FAI structures involved -Abnormal shape and abutment of femoral neck, acetabulum, and/or labrum as well as the femoral head aka hip dysplasia -With or without OA/labral tears -Trauma: less common, typically thru forceful rotation in hyperextension
FAI structures involved: Labral tears -Active individuals w/ mechanical groin pain w/out alternative radiological dx -20% of athletes with groin P! -22-55% prevalence in those with hip and groin P! -Prevalent w/ avascular necrosis and OA & chondral damage, the latter up to 73% of pts.

OA PT Rx cont. -Step w/ optimal stresses -Effective for reducing P! & disability vs. no exercise -Better than usual care out to 1 yr. -Emphasize LE control -Moderate support for flexibility, strengthening, and endurance (tissue proliferation)
Pelvis and Hip Joint Prognosis FAI and labral tears contribute to OA
FAI/ OA MD Rx -Ultrasound/ Fluoroscopic guided injections -Sx- open or arthroscopy for FAI -benefical short/ mid term follow up -No evidence to suggest sx is better than PT -Arthroscopy

THA Prosthetics -Acetabulum is rasped out and the head of the femur is cut off Metal, ceramics, plastic Mobile bearing hip -Prosthesis fixation Cemented > non-cemented; Decreased wt. bearing non-cemented; Why?
THA Complications -Bruising, DVT’s, PE (.4% at 90 days), and mortality (.5%) -Component loosening = 10-40% by 10 yrs. -Dislocation = 1-4% -Metal on metal failure rate > other materials -Metal debris can enters adjacent tissue and possibly blood
