Skeletal Pathology

Skeletal system has 206 bones

Anatomy of Bone

Osteoporosis- Osteoporosis-disease characterized by low bone mass & structural deterioration of bone tissue normal bone osteoporotic bone

Skeletal pathology

Osteochondroma

Osteochondroma

Osteosarcoma of Femur

metastatic cancer (radius)

Giant Cell Tumor Pelvis--left ischial ramus

Giant Cell Tumor--proximal femur

Bone metastases of spine & pelvis dark spots indicate osteolytic lesions (destroy bone)

MRI scan of spine demonstrates metastatic lesion destroying C7

Osteopetrosis Failure of osteoclastosis Note unusual bone density

Paget’s Disease Note hazy appearance of cranium

Radiograph-- Scoliosis (lateral curvature of spine)

Mild scoliosis in lumbar region

compression fractures due to osteoporosis that results in kyphosis MRI of Spine

Compression Fx. Collapse of vertebra What’s left of vertebral body

Herniated disk compressing spinal cord.

Osteoarthritis of vertebral column

Normal femoral head removed after fracture. Note smooth articular cartilage.

Arthritic femoral head removed due to disease. Note rough articular surface.

Osteoarthritis (proximal femur)

Osteoarthritis anterior/ superior patella & posterior tibia

Bunions

Rheumatoid Arthritis

Rheumatoid nodules at pressure points of elbows

Gout from sodium urate crystals deposited in joints.

Chronic gout eventually destroys bone. Early stage of gout.More advanced stage.
