Hip Dysplasia
What is hip dysplasia?
The hip is a ball-and-socket joint. Normally, the ball at the top of the thigh bone fits into the hip socket. Hip dysplasia occurs when the hip joint has not developed properly and the socket (acetabulum) is too shallow. This allows the ball (femoral head) to slip partially or completely out of the joint. Hip dysplasia ranges from a mild abnormality to a complete dislocation of the hip.
通常在婴儿生命的头几个月内进行常规筛查中诊断出严重的髋关节发育不全病例。其他时候，随着孩子的成长并变得更加活跃，问题可能会变得明显。
Hip dysplasia is a treatable condition. However, if left untreated, it can cause irreversible damage that will cause pain and loss of function later in life. It is the leading cause of earlyarthritis of the hipbefore the age of 60. The severity of the condition and catching it late increase the risk of arthritis. Therefore, monitoring and early intervention are both important to reduce a child’s risk of pain and disability in adulthood.
Who is affected?
髋关节发育不良会影响任何年龄的人。尽管据信它会在出生左右发展，但患有轻度发育不良的孩子可能已经多年甚至几十年没有症状。
- 婴儿的髋关节发育不良被称为婴儿developmental dysplasia of the hip (DDH).
- When diagnosed in青少年和年轻人, it is sometimes calledacetabular dysplasia.
患有髋关节发育不全的大孩子和年轻人开始注意到症状的年龄取决于病情的严重程度及其活动水平。通过参加舞蹈，曲棍球，足球，足球或田径运动来减轻大量负担的运动员可能会早日出现症状。

Undiagnosed hip dysplasia caused such severe knee pain, this former track star sometimes had trouble walking after competitions. With surgery behind her, and a degree in medicine in the works, she has returned to the sport she loves.
Girls and women are two to four times more likely than boys to have hip dysplasia. It also tends to affect first-born children and those who have a close family member with hip problems. Some people with hip dysplasia are affected in only one hip while others have it in both hips.
在男孩中，这种疾病往往伴随着其他髋关节问题。其中包括髋臼逆转录（当髋关节插座在股骨头顶上生长得太远时）或凸轮病变（骨骼表面上额外的骨骼生长会导致额外的摩擦和关节损伤）。
Hip dysplasia is sometimes confused withhip impingement, which occurs when extra bone grow on the acetabulum or femoral head. The irregular shape creates friction within the joint and wears down cartilage. Some patients have both conditions, both of which cause hip pain and are easy to confuse. However, they are different issues that require different treatments.

In a healthy hip joint, the head the femur fits comfortably inside the hip socket. With hip dysplasia, children’s hips are prone to partially or fully dislocate. Partial dislocation is also known as subluxation.
Generally speaking, treating hip dysplasia as early as possible can minimize joint damage and reduce the chance of early onset arthritis.
