Orthopedic aspects of collagen disorders

The purpose of this article is to provide the pediatrician with a review of disorders that have the orthopedic manifestation of joint hypermobility. Hypermobility, also termed ligamentous laxity, may present in different parts of the body at different times throughout childhood and adolescence. It may be symptomatic or incidentally found on the physical examination. Many conditions that cause joint hypermobility resolve with nonoperative management, but occasionally operative intervention is required for the best patient outcome.

In addition, hypermobility may be associated with collagen disorders that affect vital organ systems. Recognition of hypermobility combined with a thorough patient evaluation may be the initial opportunity for the pediatrician to uncover disease that may be managed promptly.

Heightened awareness of subtle hypermobility or symptomatic joint laxity on physical examination facilitates optimal management and favorable outcomes in children with this condition.
