What is femoral anteversion?
股骨前的是大腿骨（股骨）的内向扭曲。股骨前替代会导致孩子的膝盖和脚向内转，并具有“鸽子托”的外观。这也称为脚踏板。
多达10％的儿童出现股骨前剂。在女孩中，这种情况比男孩更普遍。它经常但并非总是会影响双腿。
Most children don't need treatment for femoral anteversion — the condition usually resolves on its own. For kids who need surgery for a severe form of the condition, the outlook is excellent. The surgeries are quite safe.
Femoral anteversion typically does not lead to关节炎or any other future health problems.
What are the symptoms of femoral anteversion?
在幼儿和患有臀部的幼儿中，与鸽子的行走是正常的。即使是由股骨前抗衡引起的，向内的脚趾也通常是在孩子学习走路时独自伸直的。
Signs of femoral anteversion usually first become noticeable when a child is between 2 to 4 years old, a time when inward rotation from the hip tends to increase. The condition becomes most obvious when a child is 5 to 6 years old.
如果您的孩子有以下任何股骨前症状的症状，最好与他们的医生交谈：
- 鸽子脚趾走路
- inability to walk with their feet close together and legs straight
- running with their legs swinging out
- tripping and falling often
是什么引起股骨前的？
股骨前通常被认为是正常发育的变化。医生不知道是什么原因或为什么有些孩子会出现严重的股骨前。
How serious is femoral anteversion?
For the vast majority of children, femoral anteversion is a minor condition that self-corrects by adolescence. Very few cases are painful or severe enough to require surgery.

Femoral Anteversion |诊断和治疗
How is femoral anteversion diagnosed?
您的孩子的医生将进行身体检查以诊断股骨前。作为考试的一部分，医生将带走您孩子的完全产前，出生和家庭病史。
The physical exam also includes measurements to determine the degree of your child’s in-toeing. These measurements can be obtained easily just by placing ink or chalk on the bottom of your child's feet and having them walk on paper to leave an impression.
医生可以使用诊断测试来获取孩子大腿骨和髋关节的详细图像，包括：
- 计算机断层扫描（CT或CAT）扫描使用X射线设备和功能强大的计算机来创建孩子身体的详细的横截面图像。CT扫描是用于确认股骨前诊断的主要成像测试。它比MRI快，比X射线更详细。
- MRI（磁共振成像）使用磁铁，无线电频率和计算机来制作孩子体内器官和结构的详细图像。
- X-raysuse invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs.
How is femoral anteversion treated?
Doctors treat most children who have femoral anteversion with close observation over the course of several years. For most children, the twisting of the thigh bone usually corrects by itself with time. Most children achieve normal or near-normal walking patterns by the time they are 8 to 10 years old. Others achieve normal walking patterns by the time they reach their teen years.
Braces, special shoes, and exercises don't usually speed up or help the body's own mechanism for self-correcting femoral anteversion. However, your child’s doctor may recommend one of these treatments if your child’s feet point inward severely or if the condition is not getting better over time.
What are the surgical options for femoral anteversion?
In a very few cases, the twisting-in may be severe and may not self-correct by the time a child is age 8 or 9. For children with severe, unresolved femoral anteversion at that age, doctors may perform surgery to reposition the femur at a more normal angle.
During the procedure (called a femoral derotation osteotomy) the surgeon cuts the femur, rotates the ball of the femur in the hip socket to a normal position, and reattaches the bone.
What is the recovery process from femoral anteversion surgery?
手术后，您的孩子可能会在医院住几天，并接受止痛药。当您的孩子回家时，他们需要限制承重活动，并可能使用拐杖或步行者几周。物理疗法将有助于恢复孩子的肌肉力量。三四个月后，他们可能会恢复包括运动在内的全面活动。
What is the long-term outlook for children with femoral anteversion?
Femoral anteversion is self-correcting in up to 99 percent of cases, and the long-term outlook is very positive for most children with the condition. Femoral anteversion doesn't typically lead to arthritis or any other future health problems.
The outlook is also excellent for children with a severe form of the condition who need surgery. The surgery itself is quite safe. In addition, children's bones usually heal faster and more reliably than adults.
