• Osteogenesis: bone formation.

• Osteomalacia: softening of bones.

• Osteomyelitis: inflammation of bone or bone marrow.

• Osteopenia: decreased calcification.

• Osteoporosis: porous and brittle bone condition.

Axial Skeleton

• Structure: vertebral column including vertebrae, intervertebral discs, and spinal cord.

• Curvatures:

  • Kyphosis: posterior curvature of the spine.

  • Scoliosis: lateral curvature of the spine.

Skull and Face Definitions

• Cranium: the upper part of the skull.

• Mandible: the lower jawbone.

• Maxilla: the upper jawbone.

• Zygoma: cheekbone.

Shoulder Girdle and Upper Limb

Common Disorders

• Shoulder Separation: dislocation of the AC joint.

• Shoulder Subluxation: incomplete dislocation.

• Tennis Elbow: tears in ligaments and muscle tendons.

• Bursitis: inflammation of the synovial fluid sac.

Hip and Pelvic Girdle

Functions

• Supports axial skeleton and transmits weight to lower limbs.

• Protects internal organs.

Disorders

• Sacroiliac Joint Strain: wear and tear causing lower back pain.

• Diastasis Symphysis Pubis: painful widening of the pubic joint.

Diagnostic Procedures for Bone Disorders

• Bone Mineral Density (BMD): using DEXA scan.

• Nuclear Bone Scan: imaging with radioactive substances.

• Blood Tests: measuring serum calcium and phosphate levels.

• Biopsy: examining bone tissue.

Therapeutic Procedures

• Surgery: for tumor removal.

• Chemotherapy: in treatment of cancers.

• Radiotherapy: using high energy X-rays.

• Cryosurgery: utilizing liquid nitrogen for cancer cell destruction.

Final Words
