Coxa magna is the asymmetrical, circumferential enlargement and deformation of the femoral head and neck. Definitions in the literature vary but enlargement with asymmetry >10% in size is a reasonable cut-off for diagnosis 1.
What is COXA Plana disease?
Coxa plana is flattening of the femoral head epiphysis and is associated with many skeletal disorders: Legg-Calv-Perthes disease.
What is COXA Breva?
coxa breva: short femoral neck with a small femoral head caused by premature closure of the epiphysis.
Which is true about Perthes disease?
Perthes disease is a rare childhood condition that affects the hip. It occurs when the blood supply to the rounded head of the femur (thighbone) is temporarily disrupted. Without an adequate blood supply, the bone cells die, a process called avascular necrosis.
What are the signs and symptoms of Legg Perthes disease?
Signs and symptoms of Legg-Calve-Perthes disease include:
- Pain or stiffness in the hip, groin, thigh or knee.
- Limited range of motion of the hip joint.
- Pain that worsens with activity and improves with rest.
What causes COXA Vara?
The most common cause of coxa vara is either congenital or developmental. Other common causes include metabolic bone diseases (e.g. Paget’s disease of bone), post-Perthes deformity, osteomyelitis, and post traumatic (due to improper healing of a fracture between the greater and lesser trochanter).
Are you born with Perthes disease?
Perthes disease is a rare childhood condition affecting the hip joint.
What are the long term effects of Perthes disease?
What are the long-term effects of Perthes’ disease? These depend on how severely the shape of the hip joint is altered by the disease. Some patients will end up with painful arthritis at some stage in adult life and may require a hip replacement.
Is Perthes disease an autoimmune disease?
Legg-Calv-Perthes Disease is an inflammatory disease causing the degeneration of the head of the femur (thigh bone) leading to the disintegration of the hip joint. LCP may be autoimmune in origin.
What is COXA Valga?
Coxa valga (KAHKS-uh VAL-guh) is a deformity of the femur, the upper thighbone that sits in the socket of the hip. hip deformity in which the angle between the shaft of the thighbone (femur) and the top of the thighbone is too great.
What is Protrusio?
Acetabular protrusion, also known as protrusio acetabuli, is intrapelvic displacement of the acetabulum and femoral head, so that the femoral head projects medial to the ilioischial line. It should be differentiated from coxa profunda.
What is coxa vara and coxa Valga?
Coxa valga is a deformity due to an increase in the angle between the head and neck of the femur and its shaft (normally 135 degrees). Coxa vara is the opposite: a decreased angle between the head and neck of the femur and its shaft.
What is purse disease?
Legg-Calve-Perthes disease, also known as Perthes disease, is a disorder of the hip in young children that usually occurs between the ages of 4 and 10. The hip is made up of the femoral head the ball, which is the upper part of the femur and the acetabulum the cup that fits around the femoral head.
Is Perthes hereditary?
Is Perthes disease hereditary? Legg-Calve-Perthes disease (LCPD) is usually not caused by genetic factors (thus is usually not inherited ), but there are some cases where LCPD affects more than one family member.
How do you fix Perthes disease?
How is Legg-Calve-Perthes disease treated?
- activity restrictions.
- anti-inflammatory medication.
- bed rest and traction.
- casting or bracing to:
- physical therapy, to keep the hip muscles strong and promote hip movement.
Is Perthes disease life threatening?
While Legg-Calv-Perthes disease is not life threatening, it is certainly life altering, with restricted mobility in a child’s daily life as something to be endured, instead of fully enjoyed. The emotional pain from Perthes can be just as overwhelming as the physical.
Is Perthes painless?
Signs and symptoms of Perthes disease can include: walking with a limp (can be a painless limp) limited range of motion and stiffness in the hip, groin, thigh, or knee.
Does Perthes disease run families?
Legg-Calve-Perthes disease (LCPD) is usually not caused by genetic factors (thus is usually not inherited ), but there are some cases where LCPD affects more than one family member. In a small percentage of these familial cases, changes or mutations in the COL2A1 gene have been found to cause LCPD.
How do you know if you have coxa vara?
Coxa vara usually presents with a limp, a leg length difference, and limited ability to bring the thigh out to the side. X-rays are used to diagnose coxa vara. Depending on what caused the condition and how severe the deformity, reconstructive surgery may be needed to improve the hip alignment and biomechanics.
Does coxa vara cause Genu Varum?
Coxa valga can be associated with genu varum and lead to increased stress and early degenerative changes in the medial compartment of the knee. Coxa valga can be treated with varus derotation osteotomy (VDRO) and angled blade-plate fixation 2.
Does coxa vara cause genu Valgum?
Operative correction of coxa vara acutely moves the mechanical axis farther laterally, causing the occult genu valgum to become clinically apparent.
What is Perth disease?
Perthes’ disease is an uncommon condition that affects children between the ages of three and 11 years. Blood supply to the head of the thigh bone is disrupted which causes the bone to deteriorate. This can cause pain, limping and limited movement of the hip joint.
Can Perthes disease cause problems later in life?
Perthes’ disease is a condition where the top of the thigh bone in the hip joint (the femoral head) loses its blood supply and so the bone is damaged. The bone gradually heals and reforms but Perthes’ disease may cause hip problems later in life.
Can Perthes recur?
Introduction: Legg-Perthes-Calv disease (LPC), or primitive hip osteochondritis, is a frequent pathology but in which recurrence is extremely rare.
Can Perthes disease cause back pain?
A follow-up of 96 patients with Perthes’ disease was made 28-47 years after onset of the disease. We paid special attention to leg-length inequality and its consequences and low-back disability. Leg-length inequality was a common finding, but low-back pain was not a significant problem.
Can adults have Perthes disease?
Only a limited number of patients that suffered from Legg-Calv-Perthes’ disease (LCPD) develop pain in early adulthood. Classical hinged abduction is well known and is thought to be responsible for secondary lateral insufficiency of the acetabulum, which may become painful.
Does Perthes disease affect growth?
Growth in 110 children with Legg-Calve-Perthes’ disease (LCPD) was longitudinally followed throughout the growth period. The infancy childhood puberty (ICP) growth model, which has the advantage that reference values can be adjusted for the individual age at pubertal maturation, was used.
What causes lack of blood flow to the hip?
Injuries, such as hip dislocation or fracture, can damage nearby blood vessels and reduce blood flow to bones. Steroid use. Use of high-dose corticosteroids, such as prednisone, is a common cause of avascular necrosis.
Is swimming good for Perthes disease?
Most children who are diagnosed with Perthes disease before the age of 6 have a favorable long term outcome regardless of the treatment. Most doctors recommend some activity restrictions, avoiding impact activities like running and jumping, while still allowing biking and swimming.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
