Articular hypermobility in Icelandic 12-year-olds
1Landspítalinn University Hospital, Reykjavík, Iceland.
Objective:
To examine the prevalence of articular hypermobility and its relationship to musculoskeletal pain in Icelandic 12-yr-olds, and to obtain baseline data for a prospective study on the subject.
Methods:
A total of 267 12-yr-olds were examined for articular hypermobility by the Beighton criteria. The children also answered a questionnaire concerning musculoskeletal pain and injuries, sports and musical activity.
Results:
The prevalence of hypermobility (defined as >/=4 Beighton criteria) was 40.5% in girls and 12.9% in boys. Despite slight trends for hypermobile subjects to be less active in sports and to report more joint pain, no correlation could be found between hypermobility and musculoskeletal symptoms.
Conclusions:
An unusually marked sex difference in hypermobility exists among Icelandic 12-yr-olds, but hypermobility does not seem to affect joint symptoms or leisure activities at this age.

Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...
Structural Joints: Synovial Joints
Ankle Joint
Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
