Quiz #4 Flashcards
Hip Joints
Pubic Symphysis
Aka: Pubic Joint
Type of Joint: Cartilaginous, Symphysis, Amphiarthrosis, Uniaxial
Articular Surfaces: symphyseal surfaces covered by hyaline of two pubic bones
Accessory Ligaments: superior pubic ligament and inferior (arcuate) pubic ligament, fibrocartilaginour disc.
Motions: Gliding, Very little movement up to 2mm
Hip Joints
Acetabulofemoral Joint
Type of Joint: Synovial, Ball & Socket (Spheroid), Diarthrotic, Triaxial
Articular Surfaces: Convex head of the femur with concave lunate surface of the acetabulum on the labrum?
Ligaments: Fibrous capsule, labrum, zona orbicularis, ligamentum capitis femoris (ligamentum teres), transverse acetabular, iliofemoral (Y ligament of Bigelow), Pubofemoral and ischiofemoral ligaments.
Motions: Flexion, Extension, Adduction, Abduction, Medial or Internal rotation, Lateral or External rotatation, Circumduction.
Hip Joint
Pubic Symphysis
Loose/Close Packed Position
Capsular Pattern of Restriction
No loose packed position or close packed position for this joint.
Capsular pattern of restriction: Pain when the joint is stressed.
Hip Joint
Hip Joint Forces
Standing = 0.3 x your body weight
Standing on 1 leg = 2.5 x your body weight
Walking = 3 x your body weight
Running = 4.5 x your body weight
Hip Joint
AF Joint
Closed + Loose packed position
Loose Packed or Resting Position:
30 degrees of flexion, 30 degrees of abduction, slight lateral rotation
Close Packed position:
Full extension, medial rotation, abduction
Hip joints
AF Joint
Capsular Pattern of Restriction
Flexion
Abduction
Medial Rotation
Acetabulofemoral Joint
AROM
Flexion = 110º - 120º
Extension = 10º - 15º
Internal/Medial Roatation = 30º - 40º
External/Lareral Rotation = 40º - 60º
Abduction = 30º - 50º
Adduction = 30º
AF Joint: Arthrokinematics
…………………Roll & Glide / Slide…………………
Flexion = Anterior , Posterior
Extension = Posterior , Anterior
Abduction = Lateral , Inferior
Adduction = Medial , Superior
Internal Rotation = Medial , Posterior
External Rotation = Lateral , Anterior
Roll & Glide occur in opposite directions
Hip Joints
Sacroiliac Joint
Type of Joint: Synovial, Plane, (also Fibrous, Syndesmosis), Diarthrotic, & Amphiarthrosis
Articular Surfaces: C - shaped auricular surface, concave sacral surface (covered in hyaline cartilage on sacrum; C - shaped auricular surface, convex ilium surface (covered in fibrocartilage) on the ilium.
Ligaments: Joint Capsule, Iliolumbar ligaments, anterior sacroiliac ligaments, interosseous, posterior; long & short sacriliac ligaments, sacrotuberous ligaments and sacrospinous ligaments.
Motions: Gliding (slight), nutation and counternutation
Nutation
- Base of sacrum moves inferiorly and anteriorly
- Enlarges pelvic outlet
- Ischial Tuberosities move apart
- Symphysis pubis approximates
- Iliac crest approximate
- PSIS seperates
- ASIS flares in
Counter Nutation
- Base of sacrum moves superiorly and posteriorly
- Enlarges the pelvic inlet
- Ischial tuberosities approximate
- Pubic Symphysis seperates
- Iliac crests seperate
- PSIS approximates
- ASIS flares out
SI Joint
Closed and Loose Packed position
Loose packed or resting position:
neutral
Closed packed position:
full nutation
Capsular Pattern of Restriction SI Joint
Pain with stressing the joint
Sacrococcygeal Joint
Type of Joint: Cartilaginous, Symphysis, Amphiarthrosis, Uniaxial
Articular Surfaces: inferior surface of sacrum apex with superior surface of coccyx base
Ligaments: Fibrocartilaginous disc, sacroccygeal ligaments (anterior, lateral, superficial posterior, deep posterior) and intercornual
Motions; little bit of flexion and extension, during defication and childbirth fuses with age.
