|
What makes up the hip joint? |
The pelvis and femur |
|
|
Is the hip joint stable? |
Yes, very stable joint bc it is WB |
|
|
What are the three ligaments of the hip? |
Iliofemoral Ischiofemoral Pubofemoral |
|
|
Which ligament is the strongest? |
Iliofemoral **creates Y Shape ligament of Bigalow |
|
|
What surface is concave/convex of the hip? |
Concave-acetabulum Convex-femoral head |
|
|
If you have weak hip abductor, extensor, and ER muscles what occurs? |
Patellofemoral impairment ACL stress Q angle can predispose valgus moment |
|
|
What does a greater Q angle mean? |
Genu valgus (unless strong hip abductors) ACL tears can also occur |
|
|
What are some abnormal structures of the hip? |
1. Unilateral shorter femur or tibia 2. Coxa Valga or coxa vara 3. Anteversion or retroversion |
|
|
anteversion |
Abnormal rotation of femur anteriorly that results in "toeing in" |
|
|
Retroversion |
Abnormal rotation of femur posteriorly that results in "Toeing out" |
|
|
Coxa valga |
Greater than normal angle of the femoral head and line of femoral shaft. Results in genu varum and hip abduction |
|
|
Coxa vara |
Less than normal angle of the femoral head and the line of femoral shaft. Results in genu valgum and hip adduction |
|
|
During anteversion and retroversion, why does Toeing in/out occur? |
To get back to midline and have the femoral head sit in the socket |
|
|
What is the normal degree of anteversion? |
8-15 degrees is normal |
|
|
What do the hip flexors due during gait? |
Control hip extension in swing phase |
|
|
If you have weak hip flexors, what occurs during gait? |
posterior trunk lean at swing |
|
|
If you have a hip flexion contracture, what occurs? |
Less extension, forward trunk, lordosis |
|
|
What do the hip extensors do during gait? |
Control flexion during loading, extension in stance |
|
|
If your hip extensors were weak, what would occur during gait? |
POsterior trunk lean at beginning of stance |
|
|
What do the hip abductors do during gait? |
Control opposite pelvic drop |
|
|
What are some conditions that result in hip hypomobility? |
OA Post-immobilization |
|
|
What are symptoms of joint hypomobility? |
Groin pain Stiffness with rest Limited ROm Asymmetry WB Antalgic gait impaired balance |
|
|
During the acute phase of hip hypomobility, what are the management protocols? |
Pt. Ed. AD Elevate seat/ grab bars Non-impact activities
|
|
|
During the Subacute/chronic phase of hip hypomobility, what are the management protocols? |
Increase joint ROM Stabilize joint Muscle Strengthening balance and aerobic capacity |
|
|
What are indications for a hip reconstruction? |
Advanced arthritis Trauma Deformation Previous Surgical Failure |
|
|
What is hip resurfacing/ |
Bone saving process. Shave off the top of the femoral head but you have to cap the femoral head to increase strength |
|
|
What are precautions for a posterior hip replacement? |
1. no flexion greater than 90 degrees 2. No IR 3. No adduction past midline |
|
|
What are post op management with hip replacements? |
Immobilization WB consideration Exercise Progression Functional Training Accelerated rehabilitation |
|
|
ORIF hip fracture |
open reduction internal fixation |
|
|
ORIF precautions |
No hip precautions! |
|
|
What are some causes of painful hip syndromes non-op? |
Strains Tendinitis Bursitis |
|
|
What is the treatment for painful hip syndromes non-op? |
Gentle stretching, gradual strengthening Address functional cause Avoid re-aggravation Correct asymmetries |
|
|
What is the most common bursa to get bursitis? |
Trochanteric |
|
|
What causes tendinitis? |
Overuse/overexertion |
|
|
What are some names of painful hip syndromes? |
Congenital malformation LEGG calve perthes Dislocations Hip pointer Snapping hip syndrome; ITB/TFL syndrome |
