An adult would typically have woven or unorganized bone under certain circumstances such as:
Fracture healing: After a bone fracture, woven bone may form initially as part of the healing process. It serves as a temporary scaffold to bridge the fracture site before being remodeled into more organized lamellar bone.
Bone repair in pathological conditions: In certain pathological conditions or diseases that affect bone, such as osteomyelitis or tumors, woven bone may form as a response to the damage or infection. It is a rapid but less structurally organized form of bone deposition.
Rapid bone growth: During periods of rapid bone growth, such as during childhood and adolescence, woven bone may be present as part of the bone remodeling process. As the bone grows and matures, woven bone is gradually replaced by more organized and stronger lamellar bone.
It's important to note that woven bone is typically temporary and undergoes remodeling to become lamellar bone, which is the more mature and organized form of bone found in adults.
