RETROVERTED ACETABULUM: Acetabular Retroversion is a little-known variety of hip dysplasia. In the normal hip, the alignment of the opening of the acetabulum is anteverted (i.e., it inclines or toward the front of the body so that if you were standing in front of it, you could see part of the inside of the cup).
Do I have Retroverted hips?
If you are within 8-15 degrees, this is considered “normal” for the hip. If you are greater than 15 degrees of hip internal rotation when testing this, the hips are considered anteverted. If you are less than 8 degrees of hip internal rotation when testing this, the hips are considered retroverted.
How is hip retroversion treated?
As the underlying problem with acetabular retroversion is one of the hip joint being malpositioned, it may require correction with surgery. Having an acetabular retroversion treatment may involve either arthroscopic trimming of the bone, or osteotomy (cutting the pelvis and realigning it).
What is normal hip retroversion?
The normal femoral anteversion in adults ranges from 15 to 20 degrees. With an excessively anteverted femur, the thigh bone's angle goes way above the average range and results in the inward-turning of the knees and feet. Usually, children are born with as much as 40 degrees of femoral anteversion.
What is an Anteverted hip?
Also called hip anteversion, femoral anteversion is a forward (inward) rotation in the femur (thighbone), which connects to the pelvis to form the hip joint. In other words the knee is excessively twisted inward relative to the hip. Femoral anteversion can occur in one or both legs.
Is femoral retroversion a disability?
Their feet are turned out while they walk, and this makes it difficult for them to stand and move normally. It is important that the condition be treated early because it can cause pain and long-term disability as the child grows older, because of the pressure that it puts on the joints around the feet, hips, and legs.
What causes acetabular retroversion?
There is no known cause for acetabular retroversion, however it may commonly exist with other hip problems such as FAI (femoroacetabular impingment), SCFE, and Perthes Disease. In many cases Acetabular Retroversion may be an incidental finding noticed on X-rays or scans without any problems at all.

What is it called when your hips turn in?
Femoral anteversion describes the inward rotation of the femur bone in the upper leg. Femoral anteversion occurs in up to 10 percent of children; 99 percent of cases resolve over time without the need for surgery. In many cases, the abnormal rotation of the femur develops while the fetus is growing in the womb.
How do I know if my femur is rotating?
One of the easiest ways to test this is to place your feet under your hips and point them straight ahead. Then notice where you knees point. If they point inward rather than forward, then you have internally rotated femurs.
What does hip dysplasia look like in adults?
The first sign of hip dysplasia in an adolescent or young adult is typically hip pain and/or a limp. This is usually in the groin area and/or lateral aspect of the hip. Pain is usually increased by activity and diminished by rest.
What is uterus Retroverted?
Retroversion of the uterus occurs when a woman's uterus (womb) tilts backward rather than forward. It is commonly called a "tipped uterus." External structures of the female reproductive anatomy include the labium minora and majora, the vagina and the clitoris.
Does physical therapy help femoral anteversion?
A common symptom of femoral anteversion is sitting in the “w- position”. Treatment may include physical therapy to teach the correct positioning of walking, and occasionally, braces to shift the bone.
How long is recovery from femoral osteotomy?
Recovery from Proximal Femoral Osteotomy On the second postoperative day, you will be encouraged to stand with a walker and begin touch-down weight-bearing for increasing periods of time. You may require crutches for 6-8 weeks for weight-bearing. It may take around 3 months to resume most of your normal activities.

How do you fix femoral anteversion in adults?
A closed, subtrochanteric derotation osteotomy of the femur is a safe and effective procedure to treat either femoral retroversion or excessive anteversion. Excellent or good results were obtained in 93%, despite the need for subsequent implant removal in more than two-thirds of the patients.
What is a Periacetabular osteotomy?
Periacetabular osteotomy (PAO) is a surgical procedure that changes the angle of the hip socket so that the ball-shaped femoral head fits more securely inside of it.
How to tell if hips are retroverted?
Standing. A quick way to get an indicator of hip retroversion is to look at the person in stance. If they naturally stand with their feet and knees both facing straight ahead, or their knees facing inward, they probably don’t have retroverted hips. (Not a guarantee.)
What is the difference between lateral and medial rotation?
Specifically, limited ability to rotate the leg out (medial / internal rotation), but excessive ability to rotate the leg in (external / lateral rotation).
What is the difference between retroversion and anteversion?
In terms of side to side movement: Anteversion: The hip joint has a propensity to adduct. Retroversion: The hip joint has a propensity to abduct. Simplified:
What is the first area of confusion when talking about structural issues at the hip?
When talking about structural issues at the hip the first area causing confusion (at least for me) is the lack of discernment between acetabular abnormality and femoral abnormality.
Why is my hip limited into external rotation?
In prone, if the hip is limited into external rotation you can’t deduce it’s because of a structural issue at the hip; it’s probably muscular, like a stiff TFL.
How to get around a femur?
One way to try and get around this is to have the person open their feet and knees more. This will give the person extra room to internally rotate the femur.
How to do a squat on your stomach?
Have the person lay on their stomach, bend one knee, then rotate the leg side to side (making sure the lower back does not move).
What is acetabular retroversion?
Acetabular retroversion is a form of hip dysplasia (where the hip fails to form normally). There is no known cause for acetabular retroversion, however it may commonly exist with other hip problems such as FAI (femoroacetabular impingment), SCFE, and Perthes Disease.
What is the green arrow on a CT scan?
Above: CT Scans are very useful for looking at the acetabular position – in cross section above the blue arrow is the front wall and the green arrow is the back wall.
Which scan is the most accurate for looking at the bone and associated soft tissue structure of the hip joint?
CT Scans and MRI scans are very useful as they give a cross – sectional picture of the acetabulum and are the most accurate for looking at the bone and associated soft tissue structure of the hip joint.
Can retroversion be missed on X-rays?
In many cases Acetabular Retroversion may be missed on plain X-rays. It is recommended that Specialist Musculoskeletal Radiologists, or Specialist Hip Surgeons assess x-rays looking for Acetabular Retroversion. The signs on X-rays are often subtle and easily missed, and good quality X-rays are essential for the diagnosis.
Can acetabular retroversion be seen on X-rays?
In many cases Acetabular Retroversion may be an incidental finding noticed on X-rays or scans without any problems at all. However, some patients may develop symptoms due to the femur (thighbone) abnormally hitting the pelvis, or instability from the femoral head slipping backwards out of the hip joint.
What is fetal retroversion?
Femoral retroversion is a positional deformity caused by contracture of the external rotator muscles of the hip. It becomes apparent as the child starts to stand or cruise between 6 and 9 months. Tightness of the muscles of the hip that cause the hip to rotate excessively to the outside. Primarily caused by in utero position.
What causes a twist in the lower leg?
Primarily caused by in utero position. Rarely caused by bone deformity in which there is an actual external twist of the lower portion of the upper leg bone (femur) relative to the upper portion of the upper leg bone (femur). SIGNS AND SYMPTOMS:
Why do flat feet get worse?
Usually associated with flatfeet. Due to the significant external foot progression angle (foot pointing extremely to the outside) a flatfoot develops or worsens as the child is walking through the arch and not over the ball of the foot. Extreme poor push off power. Runs very poorly.
Why do you cast your leg?
It may be necessary to place the leg in a cast to stretch the ligamentous and muscular structures on the outside of the knee, which can hold the lower leg externally positioned relative to the upper leg.
Why do you need custom orthotics?
A custom molded orthotic for the shoe at a very early age to prevent the foot from breaking down even further and to provide support necessary for ambulation.
What degree of motion does a child have when laying on their back?
Examination of the child off weightbearing laying in the supine (on their back) position reveals limited motion of the entire leg going internal and 80-90+ degrees of motion going externally.
What does it mean when a child lies on their back?
While the child lies on their back the outside of the leg appears to be touching the bed they are lying on. The outside of the foot (small toe side) lies flat on the bed.
What is femoral anteversion?
Also called hip anteversion, femoral anteversion is a forward (inward) rotation in the femur (thighbone), which connects to the pelvis to form the hip joint. In other words the knee is excessively twisted inward relative to the hip.
What is it called when the femur is backwards?
Femoral anteversion can occur in one or both legs. The opposite condition, in which rotation of the femur is backward (outward), is called femoral reteroversion. Many children are born with femoral anteversions that they eventually grow out of.
How to diagnose femoral anteversion?
The physician may also order X-rays or a CT scan to look for any deformity. However, in certain cases, femoral anteversion can be difficult to detect. This is especially true in cases where the hip anteversion is combined with a separate rotational bone deformity, such as external tibial torsion – an outward rotation of the tibia (shinbone). This type of complex case is called "tetra-torsional malalignment,” which has sometimes also been called "miserable malalignment syndrome." It can be hard to diagnose because:
What is anteversion in anatomy?
In anatomy, the word "version" refers to the angle or rotation of all or part of an organ, bone or other structure in the body, relative to other structures in the body. Anteversion refers to an abnormal forward rotation. What is femoral anteversion? Causes of femoral anteversion. Symptoms of femoral anteversion. Diagnosis of femoral anteversion.
What happens when the femur and tibia are parallel?
The two opposite rotations of the femur and tibia leave the patient's feet to stay parallel during walking, This means the malalignment of the hips and knees may go unnoticed, even if the patient experiences pain or discomfort.
How to compensate for hip anteversion?
Right: Most patients with excessive hip anteversion compensate by walking in-toed. This position keeps the femoral head within the socket, which minimizes pain.
What is the term for walking with a foot pointed toward the other?
In-toeing, in which a person walks "pigeon-toed," with each foot pointed slightly toward the other. Bowlegs (also called bowed legs). Keeping the legs in this position often helps a patient maintain balance. Pain in the hips, knees and/or ankles. Snapping sound in the hip while walking.
