13. Orthopedics
Learning Objectives
- Describe the scope of orthopedics and the major subspecialties within the field
- Classify fractures and dislocations by type, mechanism, and clinical presentation
- Explain the diagnostic and management approach to common musculoskeletal disorders
- Identify key differences in orthopedic presentations between children and adults
- Recognize common sports injuries and outline the rehabilitation principles used in sports medicine
- Describe the major orthopedic surgical procedures and their indications
Quick Answer
Orthopedics is the branch of medicine that diagnoses, treats, and rehabilitates conditions affecting the musculoskeletal system — bones, joints, muscles, tendons, ligaments, and nerves. It spans everything from acute fractures and sports injuries to chronic degenerative conditions like osteoarthritis and congenital disorders like clubfoot. Orthopedic care ranges from non-surgical options (physical therapy, bracing, medications) to complex procedures like total joint replacement and spinal fusion. Understanding orthopedics requires a solid foundation in anatomy, biomechanics, and diagnostic imaging.
Topics at a Glance
| Topic | Core Focus | Key Takeaway |
|---|---|---|
| Introduction to Orthopedics | History, scope, subspecialties, anatomy basics | Orthopedics covers the full musculoskeletal system |
| Fractures and Dislocations | Types, mechanisms, diagnosis, treatment | Closed vs. open fractures; RICE to surgical fixation |
| Musculoskeletal Disorders | Arthritis, osteoporosis, tendinopathies | MSDs are a leading cause of global disability |
| Pediatric Orthopedics | Growth plates, clubfoot, scoliosis, JIA | Children's bones behave differently from adults' |
| Sports Medicine | Overuse and acute injuries, rehabilitation | Return-to-sport protocols require a phased approach |
| Orthopedic Surgery Techniques | Joint replacement, spinal fusion, instruments | Surgery is guided by biomechanics and anatomy |
Key Terms
| Term | Definition | Related Concept |
|---|---|---|
| Fracture | A partial or complete break in a bone | Open vs. closed fracture, stress fracture |
| Dislocation | Displacement of a bone from its normal joint position | Acute vs. chronic dislocation |
| Arthroplasty | Surgical reconstruction or replacement of a joint | Total hip/knee replacement |
| Epiphyseal plate | Growth cartilage at the ends of long bones in children | Pediatric fractures, Salter-Harris classification |
| Osteoarthritis | Degenerative joint disease from cartilage breakdown | Arthroplasty, conservative management |
| Scoliosis | Lateral curvature of the spine | Bracing, spinal fusion |
