- Craniosynostosis (crane-eo-sin-ost-O-sis) is a birth defect in which the bones in a baby’s skull join together too early. This happens before the brain is fully formed and can slow the growth of the baby’s brain.

May 1, 2023 · Bone ossification, or osteogenesis, is the process of bone formation. This process begins between the sixth and seventh weeks of embryonic development and continues until about age twenty-five; although this varies slightly based on the individual.

Intramembranous ossification begins in utero during fetal development and continues on into adolescence. At birth, the skull and clavicles are not fully ossified nor are the junctions between the skull bone (sutures) closed.

Absence of extremities, such as amelia (complete absence of extremities), acheiria (absence of the hand), phocomelia (seal limb) or aplasia–hypoplasia of the radius or ulna, are often inherited as part of a genetic syndrome (Holt–Oram syndrome, thrombocytopenia with absent radii syndrome).
Ossification. Bone is broken down by osteoclasts, and rebuilt by osteoblasts, both of which communicate through cytokine (TGF-β, IGF) signalling. Ossification (also called osteogenesis or bone mineralization) in bone remodeling is the process of laying down new bone material by cells named osteoblasts.
Osteogenesis imperfecta (OI) is an inherited (genetic) bone disorder that is present at birth. It is also known as brittle bone disease. A child born with OI may have soft bones that break (fracture) easily, bones that are not formed normally, and other problems. Signs and symptoms may range from mild to severe.
Jan 17, 2023 · Intramembranous ossification occurs during fetal development and does not involve cartilage. Embryologic mesenchymal cells differentiate into osteogenic cells that direct bone growth from spicules to trabeculae, to woven bone, and finally to lamellar bone.
Fibrodysplasia ossificans progressiva (FOP) is a rare muskuloskeletal condition where, after birth and progressively through life, muscles and tendons are gradually transformed into bone (a process called ossification). This creates a second “skeleton” of extra bone, which makes movement impossible. The cause of FOP is unknown.
