Transcript of The Coxal Joint

the coxal joint the hip is a synovial ball-in-socket joint. this gives it a wide range of motion on multiple planes: the hip joint involves 17 muscles,
5 ligaments, 3 tendons, and 2 bones.
the gluteal group
the adductor group
the iliopsoas group
the lateral rotator group



the bones of the hip are: the ligaments of the hip are divided into two groups: the three ligaments of the hip are: diseases of the hip but we'll take a closer look at hip dysplasia diagnosis special harnesses and casts help an infant's joints to realign
the gluteus maximus & the tensor fasciae latae
origins: ilium and sacrum
insertions: femur and iliotibial tract
the gluteus medius & minimus
origins: anterior to g. maximus on the ilium
insertion: greater trochanter of femur
the adductor brevis
the adductor longus
the adductor magnus
the pectineus
origin: the pubis
insertion: posterior of femur
the gracilis
origin: the pubis
insertion: medial condyle of femur
the iliacus
origin: iliac fossa of ilium
insertion: lesser trochanter of femur
the psoas major
origin: lumbar vertebrae
insertion: lesser trochanter of femur
the externus obturator
the internus obturator
the piriformis
the superior and inferior gernelli
the quadratus femoris
origin: acetabulum of the ilium
insertion: greater trochanter of femur the muscles of the hip are divided into 4 categories: the gluteal group includes: the adductor group includes: the iliopsoas group includes: the lateral rotator group includes: extracapsular (outside the joint capsule)
intrascapular (inside the joint capsule) the iliofemoral
the ischiofemoral
extrascapular: the ligamentum teres infrascapular:
the femur
the pelvis the iliofemoral
the pubofemoral
the ischiofemoral there are many including: osteoarthritis
osteonecrosis
fracture
hip dysplasia rotation, adduction, abduction, circumduction adduction exercise! abduction flexion rotation a deformation or misalignment of the hip joint can be acquired or congenital chromosome 13 and the hormone relaxin could be causes breech birth and the use of cradle boards and swaddling cloths can permanently misalign an infant's hip treatment if this fails, surgery can alter the hip abductor and iliopsoas muscles so they adapt to a healthy joint alignment stem cells can help grow bone grafts for prostheses hip replacement surgery is sometimes necessary as unusual bone wearing leads to early osteoarthritis newborns are screened for hip dysplasia by maneuvering the joint the diagnosis is confirmed by ultrasound and x-ray the earlier it's caught, the easier it is to heal, as the bone cartilage in infants is not fully ossified take care of your hips! hip replacement suregery costs an average of $39,299! don't engage in too much high-impact exercise maintain healthy bones engage in moderate, low-impact exercise to avoid injury the pubofemoral
the zona orbicularis hip dysplasia
developmental dysplasia
