small mandible
(
J:5970
)
|
• although the mandible is proportionately smaller, the skull itself is not reduced significantly
|
|
• proximal long bones are more severely affected than distal long bones
|
|
• shortened but not narrrowed
• the point of muscle attachment at the deltoid tuberosity is increased in size giving the bone a winged shape
|
short humerus
(
J:5970
)
|
• shortened but not narrrowed with poorly developed head
• the point of muscle attachment at the trochanters is increased in size giving the bone a winged shape
|
short femur
(
J:5970
)
|
• reduced in size
|
|
• reduced in size
|
|
• growth of femora and tibiae is normal until during the first 2 weeks of life then no growth occurs between 16 and 21 days of age after which slow bone growth resumes
(J:5934)
• reduction in long bone growth is slightly more severe in proximal than in distal bones
(J:5934)
• all cartilaginous bone is affected but not all to a degree of significance
(J:5970)
|
growth/size/body
|
• there is a sudden growth check at 14 days of age
• coincident with failure of newly formed chondrocytes to migrate
|
