Insights
A rare bone disorder, Indonesian type of metaphyseal dysplasia, affects siblings with short stature and leg bowing. This autosomal recessive condition primarily impacts the lower extremities, particularly the hips.
Area of Science:
- Genetics
- Orthopedics
- Pediatrics
Background:
- Describes a novel autosomal recessive bone disorder.
- Simulates enchondromatosis, presenting diagnostic challenges.
Observation:
- Two Indonesian siblings presented with short stature and lateral bowing of lower extremities.
- Clinical features were evident at birth.
Findings:
- Metaphyseal dysplasia predominantly affected lower extremities, with severe hip joint involvement.
- Upper extremities showed minimal abnormalities.
- Radiographic examination confirmed metaphyseal anomalies.
Implications:
- Suggests a new classification: Indonesian type of metaphyseal dysplasia.
- Highlights the importance of early recognition in genetic bone disorders.
- Contributes to understanding skeletal dysplasias and their inheritance patterns.
Abstract:
The authors describe two Indonesian siblings affected by a hitherto undocumented form of metaphyseal dysplasia that simulates enchondromatosis. The notable clinical features were short stature and lateral bowing of the lower extremities. These features were readily recognizable at birth. The radiographic examinations showed that the metaphyseal anomalies were localized predominantly in the lower extremities, the hip joints being the most severely affected. The upper extremities showed only minimal abnormalities. The name "Indonesian type of metaphyseal dysplasia" is suggested for this autosomal recessive bone disorder.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Structural Joints: Fibrous Joints
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...
