occurs when the long bones stop growing in childhood, but the bones of the axial skeleton are not affected; leads to dwarfism of about 4ft tall; caused by spontaneous gene mutation
26
osteogenic sarcoma
most common malignant bone tumor; peak incidence is 10-15yo; often occurs around the knee joint
27
osteogenesis imperfecta
rare genetic disorder producing very brittle bones that are easily fracture, often in utero
28
Bone Fracture: Closed VS Open
Closed- bone is broken, but skin is not broken | Open- Fragment of the fractured bone breaks the skin, or a wound extend to the site of the fracture
29
Bone Fracture: Displaced
fractured bone parts are out of alignment
30
Bone Fracture: Complete VS Incomplete VS Comminuted
complete- broken into at least 2 fragments incomplete- fracture does not extend completely across the bone comminuted- bone breaks into several pieces, usually two major pieces and several, smaller fragments
31
Bone Fracture: Transverse
fracture is at a right angle to the long axis of the bone
32
Bone Fracture: Impacted
one gone fragment is driven into the other, resulting in a shortening of a limb
33
Bone Fracture: Spiral VS Oblique VS Linear
Spiral- fracture spirals around the long axis of the bone Oblique- diagonal fracture runs along the long axis Linear- fracture runs parallel to the long axis
34
Bone Fracture: Greenstick (closed)

35
Bone Fracture: Pathologic
aka stress fracture; fracture occurs in an area of the bone weakened by disease
36
Bone Fracture: Compression
fracture occurs in a vertebra from trauma or pathology, leading to the vertebra being crushed
37
Healing of Fractures
Step 1: blood vessels bleed into the fracture site forming a hematoma Step 2: A few days after the fracture (Fx), osteoblasts move into the hematoma and start to produce new bone; called a callus Step 3: Osteoblasts produce immature, lacy cancellous (spongy_ bone that replaces the callus Step 4: Osteoblasts continue producing bone cells ; producing compact bone and fuse the bone segments together
38
