Study Notes
- Orthopedics focuses on surgical subspecialties, addressing musculoskeletal system diseases and trauma.
- The musculoskeletal system includes bones, joints, ligaments, tendons, muscles, and nerves.
- "Orthopedics" originates from the Greek words 'Ortho,' meaning straight, and 'Pedia,' meaning child.
Orthopedics Subspecialties
- Pediatrics orthopedics addresses musculoskeletal issues in children.
- Ankle and foot surgery units specialize in surgical procedures for the foot and ankle.
- Reconstruction and deformity correction units focus on surgical corrections of deformities.
- Surgery of the upper limb and hand units specialize in surgical procedures for the upper extremities.
- Spinal surgery units focus on surgical procedures for the spine.
- Tumor units specialize in the treatment of bone and soft tissue tumors of the musculoskeletal system.
- Arthroplasty units specialize in joint replacement surgeries.
- Trauma surgery units handle surgical management of traumatic musculoskeletal injuries.
- Knee and sport medicine units specialize in knee surgeries and sports-related injuries.
Topics in Orthopedics
- Congenital talipes equinovarus (CTEV), also known as clubfoot, is a congenital deformity.
- Developmental dysplasia of the hip (DDH) is a condition where the hip joint doesn't form correctly.
- Orthopedic trauma covers fractures, which involve breaks in the bone.
- Dislocations are injuries where bones move out of their normal position at a joint.
- Fracture dislocations involve both a fracture and a dislocation at a joint.
- Osteomyelitis is an infection of the bone.
- Pyogenic arthritis is a joint infection caused by bacteria.
- Rheumatic disorders, such as rheumatoid arthritis, affect the joints and connective tissues.
- Osteosarcoma and Giant cell tumors are types of bone tumors that can occur in the musculoskeletal system.
- Cerebral palsy and spina bifida are neuromuscular disorders affecting motor function and development.
- Osteoarthritis is a degenerative joint disease.
- Rickets is a condition caused by vitamin D deficiency, leading to soft and weakened bones.
- Osteoporosis is a condition characterized by decreased bone density, increasing the risk of fractures.
Joints
- Articulation occurs between two or more bones.
Fibrous Joints
- Articulating bones are connected together by fibrous tissue.
- Sutures are joints between the bones of the skull.
- Syndesmotic joints have bones connected by strong ligaments.
Cartilaginous Joints
- Primary cartilaginous joints: bones are connected by hyaline cartilage.
- Secondary cartilaginous joints: bones are connected by fibrocartilage.
Synovial Joints
- Articular surfaces of bones are covered by a thin layer of hyaline cartilage.
- Articulating bones are separated by a joint cavity.
- The joint is surrounded by a fibrous tissue capsule.
- Joints are classified based on the tissue between the bones.
Planes of the Body

Causes of Deformities
- Genetic
- Gene disorders have characteristic patterns of inheritance.
- (autosomal or X-linked and dominant or recessive).
- Environmental
- Some teratogenic agents which damage the placenta or embryo during the first few months of gestation are:

- Viral infection (rubella).
- Certain drugs (thalidomide).
- Ionizing radiation.
- Combined Genetic and Environmental
- Acquired

- Fascial ( Dupytren’s contracture).
- Muscle (Muscle dystrophies and Volkmann’s contracture).

- Orthosis is a splint or brace.
- Osteotomy is surgically cutting the bone.
- Arthroscopy is an operation to directly view a joint, minimal access.
- Arthroplasty is the surgical replacement of a joint.
- Austin Moore’s prosthesis and Thompson’s prosthesis are examples of implants used in arthroplasty procedures.
- Arthrodesis is the surgical fusion of a joint.
Devices and Implants
- Closed reduction and external immobilization includes the use of U-shaped plaster slabs, cast braces, and hanging casts.
- K-wires, plates and screws, dynamic hip screws (DHS), and multiple cancellous screws are examples of internal fixation devices.
