However, grade III heterotopic
ossification (Brooker classification) was noted (Figure-E), which resulted in joint stiffness.
"It's a secondary center of
ossification that appears at ages 10-12 years and fuses at ages 14-18." Telltale signs are tenderness with or without swelling at the tibial tubercle that worsens with running, jumping, or impact activities.
OPLL is often complicated by
ossification of other spinal ligaments and by diffuse idiopathic skeletal hyperostosis, which suggest that the OPLL patients have the intrinsic tendency for ectopic
ossification.
Prisby wondered if the processes of
ossification in bone marrow blood vessels could give rise to bone-like particles that are capable of entering the bloodstream.
Axial skeleton shows ovoid vertebral bodies, severe platyspondyly, hypoplasia of odontoid process (which results in atlantoaxial instability that can cause cervical myelopathy), progressive kyphoscoliosis (short trunk) involving thoracic and lumbar spine, narrowing of disk spaces (resulting in short trunk), broad iliac bases, deficient
ossification of pubis and flat acetabular roof.
late), heterotopic
ossification, and deep venous thrombosis were significant factors associated with FIM gain (Table 3).
The mnemonic "CRITOE" is helpful in detecting this type of fracture, as the lateral epicondyle is the last
ossification center to appear, and if seen before any of the other
ossification centers, concern for a fracture is raised.
In 1992, University of Texas law professor Thomas McGarity coined the phrase "the
ossification of the rulemaking process" to describe the challenges agencies face in promulgating regulations.
