Abstract
Trisomy of the 21st chromosome, or Down syndrome (DS), is the most common chromosomal abnormality. It is associated with certain musculoskeletal conditions that are usually present to some degree in most individuals with Down syndrome. Musculoskeletal conditions linked to generalized ligament laxity are among the main features of this syndrome. Laxity may sometimes be concomitant with significant joint pathology, such as hip instability or patellofemoral instability. The authors present two clinical cases, one with non-traumatic hip dislocation treated conservatively with a spica cast and prolonged immobilization, and another with patellofemoral instability treated surgically. After 18 and 15 months' follow-up, neither patient has experienced a recurrence.
Keywords: Orthopedic disorders. Ligament laxity. Hip dislocation. Patellar dislocation. Down syndrome.
