Definition of Hypermobile joints:

Hypermobile joints are joints that move beyond the normal range with little effort. The joints that are most commonly hypermobile are the elbows, wrists, fingers, and knees.

Considerations:

Hypermobile joints occur in some very rare medical conditions, but can also occur in otherwise healthy and normal children. Children generally tend to be more flexible than adults, but those with hypermobile joints are capable of flexing and extending beyond normally observed limits for that particular joint. The movement is accomplished without undue force and without discomfort. Children with hypermobile joints also frequently have flat feet.

Common Causes:

• Ehlers-Danlos syndrome
• Down syndrome
• Marfan syndrome
• Morquio syndrome
• Cleidocranial dysostosis
