Disease
Log in - Calve - Perth, is the name given to the necrosis Great
idiopathic osteonecrosis Bmchach femoral head capital epiphysis, has
been named the disease the names of three doctors who described the
disease, and it happens because of poor blood supply to the femoral
head, and have twice the blood supply idiopathic ,
which is more common in male children, usually on one side of the body,
and about 10% of cases, familial familial, and the most important
symptoms are distinctive be the pain, hip joint, and disorder gait gait
disturbance, and beginning to be gradual, and progress is slow, which is
self-limited
disease, but when the disease has Émd left with a severe distortion of
the femur and the right pelvic bone, and prepare for a secondary
degenerative arthritis, and the goal of treatment is to make the
sequelae of the disease milder.
The hip jointIs
the joint that connects the femur bone pelvis, and consists of the
detailed two-part, two femoral head, which is in the shape of the ball,
and another part is the cavity of the pelvis called the right, and that
the detailed spherical acetabular ball and socket joint allows movement
of the leg in the trends of multiple for the body.
There
Pinhabat long bones - during periods of growth - parts be responsible
for bone growth, which is composed of special types of cartilage,
cartilage, or separating these parts and the leg bone cartilaginous
disk.
For
the femur the head of the femur of these parts is responsible for its
growth, and called Mshasha femoral head, which is located within the
joint capsule, and blood vessels that feed the region are going next to
the neck of the femur, may cause interruption of the supply of blood to
the femoral head - for reasons incomprehensible - in the event of malfunction of these vessels, causing illness Log in - Calve - Perth.
Bone
always done by the two operations are the construction and demolition,
and construction through the cells Albanian of bone osteoblasts, and is
destroyed by cells Naqdh of bone osteoclasts, and once the bone, the
shape and structure of their portability permanent form and re-shape,
and under these two processes solve the bone replaces the bone eroded ,
and during periods of growth to benefit from this patient Log in -
Calve - Perth, where the survival of the femoral head within the cavity
of the right to help in the reconstruction of the head round the same
rotated cavity right, who works as a template for re-formation of the
femoral head, but after puberty and stunted growth of bone, the
process of forming and re-shape mutate, and be responsible for
replacement of bone where the bone eroded only, without deposition of
bone in other places are allowed to change the form of the bone, and
therefore require patients Log in - Calve - Perth to stabilize the joint
in a situation where the femoral head within the right or to the
surgery to restructure the joint angle is kept the survival of the femoral head within the cavity of the right.
Have
advised the expert work of the surgery before puberty to install the
femoral head within the right, to speed healing, and the speed to allow
the child to walk and movement, as an alternative to other means that
require comfort for long periods in bed, and also requires restricting
the movement of the child to stabilize the joint.Disease
always include Mshasha femoral head, and in 15-20% of patients disease
Log in - Calve - Perth the infection on both sides of the body
bilateral.
Spread of the diseaseIn the United States there is one disease, injury Log in - Calve - Perth every 1,500 children younger than 15 years.
Mortality and morbidity
Log
in disease - Calve - Perth is a self-limited disease, in other words,
the disease have a limited path, or stop at the borders of offer, which
may end after 2-3 years when you do not treat, and when treatment is
less than the period of the disease and also complications.
The fate of the disease varies from case to case.
Relationship of the disease RaceCaucasians Caucasians are infected, including more than among those who are of other races.
Sex-related diseaseThe infection is 4-5 times higher among males injuries among females.
Age-related diseaseLog in disease - Calve - Perth common vision in people aged 3-12 years, on average at the age of 7 years.
Symptoms
The
symptoms of the disease existed before the child complains that a few
weeks, because in most cases the child does not complain with the onset
of the disease only when asked.
Be a gradual onset of the disease, and be slow to offer.
Hip pain hip, groin or inguinal region, which can spread to the thigh.
Mild
or intermittent pain on the front of the thigh or the knee, must
therefore be drawn to the need to examine a child when there is no
apparent reason last of the pain in these areas.
In
most cases are discovered when the disease is noted parents - or one of
those interested in children - a limp limp in children, causing them to
seek medical advice.
There is usually no history of a bruise.
Tags
Have
a limited range of motion, especially the movement of rotation of the
inside of the thigh, and keep the movement of the thigh to the outside,
and that usually means there is inflammation of the cartilage, and there
may be a gathering of liquid cartilage, which is called infiltration.
Be a painful gait.
Atrophy of the muscles of the thigh as a result stemming from the disease.
Bouts of muscle contraction and spasm of the thigh.
May occur not equal to the length of the legs as a result of atelectasis.
There
may be atrophy of the affected side of the thigh, and the surroundings
is less than the non-infected, and as a result of non-use.
Short stature, due to delayed bone age in children with disease Log in - Calve - Perth.
When
the work rotation of the hip in and out during the patient lying on his
back going guarding guarding, or muscle contraction, especially when
the rotation of the inside work.Log
in the cause of disease - Calve - Perth is still not clear, however, no
acceptable explanation for the disease which is as follows:
Cut off blood supply to the femoral head epiphysis NA.
Occurrence
of bone infarction, especially cortical bone under the cartilage (due
to be coagulation arteries feeding the femoral head), while the
articular cartilage continues to grow (and the continued growth in the
meniscus is because it derives its nutrition from the synovial fluid
inside the joint).
Back to educate occur (blood vessel) revascularization and begin to form new bone.
When
revascularization and new bone is, the proportion of patients have the
disease arises Log in - Calve - Perth, while other patients have going
development and growth of super-natural.
Log
in disease - Calve - Perth when there is no break under the cartilage,
and this is a result of physical activity, and not the result of direct
contusion of the region.
Epiphyseal growth plate changes epiphyseal growth plate fracture occurs as a result under the cartilage.
There
is no evidence that the disease is hereditary, and therefore does not
represent a danger to the children of parents infected with this
disease.
TestsLaboratory testsLaboratory tests include:
Full blood count Complete Blood Count.
Sedimentation rate of erythrocyte sedimentation rate, which may increase in case of an infection.
