X-leg

Introduction Common lower extremity malformations, mainly due to rickets or osteomalacia (the reason is the lack of vitamin D) caused by knee deformities. Other causes include spinal anterior polio, osteophyte injury, osteomyelitis, or other conditions that cause dysplasia of the femur or tibia. When the lower limbs are straight, the femur and the tibia form an outward angle, and the two knees are close together, and the distance between the two legs is increased, similar to the "X" shape, which is called knee valgus, commonly known as the X-shaped leg. Corrective rehabilitation training should be done as soon as possible for the disease.

Cause

The changes in the lower limbs during the growth period usually occur during the age of four to six years. For example, X-shaped legs still appear after the age of four to five, which may be caused by congenital inheritance or acquired posture due to poor sitting posture such as W-shaped sitting posture. There are three main reasons for the "X" leg, one is rickets in children, one is congenital inheritance, and a small part is due to sequelae caused by dysplasia, trauma, fractures, etc. Malformation not only affects shape and bodybuilding, but also has a greater impact on human health. Knee valgus or varus destroys the distribution of normal force of the knee joint, so that the biological stress on one side of the joint increases, and the opposite side decreases. Such a long time will cause pain in the knee joint walking, joint activity is also affected, and it is easy to cause osteoarthritis of the knee. Correcting this leg shape can not only improve the body shape of the body, but also improve the distribution of knee joint force. Balanced state.

General photo inspection

The X-shaped leg refers to the two legs standing together, firstly, the knee joints on both sides are touched together, and the two heels are not close together, and the gait of the two knees hitting each other is encountered while walking. When the feet are close together, only the knees can be touched, and there are gaps between the thighs and the calves.

1. Knee varus or valgus deformity, walking obstacles.

2. When the lower limbs are straight, the knees or double internal hemorrhoids are significantly separated. The distance is mild below 3 cm, moderately 3-6 cm, and severe above 6 cm.

3. X-ray film shows the deformation of the femur or tibia.

Differential diagnosis

Differential diagnosis of "X" legs:

O-leg: In the double heel, the two feet together, relax the legs upright, such as the distance between the two knees, it means there is an O-leg. Generally, the severity of the O-leg is judged according to two indexes of the normal knee distance and the active knee distance. The so-called normal knee distance refers to the distance inside the knee joint when the two legs are close together and the legs and knees are relaxed. The active knee distance refers to the distance between the two legs and the knees and the knee joints in the upright position, and the distance inside the knee joints.
