Orthopaedics is the branch of medicine concerned with the musculoskeletal system. This system includes the bones, joints, muscles, ligaments, tendons, cartilage and nerves that help the body move and provide support. Doctors who specialise in this field are called orthopaedic surgeons or orthopaedists.
Despite the word “surgeon”, orthopaedic care does not always involve an operation. Orthopaedic specialists assess injuries and conditions, explain treatment options and may recommend non-surgical care, surgery or a combination of approaches. The right plan depends on the person’s condition, its effect on everyday life and other health factors.
Orthopaedics covers a wide range of concerns, from fractures and sports injuries to arthritis, spinal conditions and problems present from birth. Some specialists care for people of all ages, while others focus on a particular part of the body, type of injury or age group.
What the Musculoskeletal System Does
The musculoskeletal system allows people to stand, move, lift objects and carry out everyday activities. Each part has a different role:
- Bones support the body, protect some internal organs and provide a framework for movement.
- Joints connect bones and allow movement between them.
- Muscles contract to create movement and help maintain posture.
- Tendons connect muscles to bones.
- Ligaments connect bones to other bones and help stabilise joints.
- Cartilage provides a smooth surface where bones meet and helps absorb pressure.
- Nerves carry signals between the brain, spinal cord and body, including signals that control movement and carry sensation.
A problem in one part of this system can affect others. For example, a joint injury may also involve ligaments, cartilage or nearby muscles. Orthopaedic assessment considers how the affected parts work together, rather than looking at a single structure in isolation.
What Orthopaedic Specialists Do
An orthopaedic specialist assesses and manages problems affecting the bones, joints and related tissues. The process may begin with a discussion about symptoms, past injuries, daily activities and medical history. The specialist may then examine the affected area and consider whether imaging or other tests would be useful.
An orthopaedic specialist may:
- Assess pain, stiffness, swelling or difficulty moving
- Diagnose injuries and musculoskeletal conditions
- Explain treatment options and likely next steps
- Recommend non-surgical care where appropriate
- Perform or arrange surgery when it is suitable
- Monitor recovery and changes over time
- Coordinate care with physiotherapists and other professionals
- Help people return to daily activities, work or sport following injury or treatment
Orthopaedic care may take place in hospitals, clinics, rehabilitation services or sports medicine settings. The exact services available vary between healthcare systems.
Conditions Treated in Orthopaedics
Orthopaedics covers many conditions. Some begin suddenly, such as a fracture after an accident. Others develop gradually, such as joint degeneration or persistent tendon problems. Some are present from birth, while others appear later in life.
Fractures
A fracture is a break in a bone. Fractures can vary in severity and may affect different parts of the body. Some are caused by a significant injury, while others can occur in bones weakened by certain conditions.
An orthopaedic specialist assesses the location and type of fracture and whether nearby joints, nerves or blood vessels may also be affected. Treatment may involve keeping the bone still while it heals, or using surgery to help align and stabilise it. The approach depends on the particular fracture and the person’s circumstances.
Joint Conditions
Joints can be affected by injury, inflammation, wear over time or structural changes. Orthopaedic specialists commonly assess problems involving the knee, hip, shoulder, ankle, wrist and elbow.
Joint conditions may cause pain, stiffness, swelling or reduced movement. Some affect the joint surface or cartilage; others involve ligaments, tendons or surrounding muscles. An assessment aims to identify the likely source of the problem and understand how much it affects function.
Arthritis
Arthritis is a general term for conditions that affect joints. Osteoarthritis is one common form and involves changes to the joint, including the cartilage and nearby structures. Other types of arthritis may be connected to inflammation or immune system activity.
Orthopaedics may be involved when arthritis affects movement or daily activities, or when a person is considering specialist treatment. Depending on the condition, care may involve non-surgical measures, medication managed by a relevant clinician, injections or joint replacement surgery. The appropriate options vary between individuals.
Sports Injuries
Sports and physical activities can place repeated or sudden forces on bones, joints and soft tissues. Common sports injuries include ligament sprains, muscle strains, tendon injuries, fractures and cartilage damage.
Orthopaedic specialists may assess the injury, determine whether additional tests are needed and discuss treatment. The goal may include relieving symptoms, protecting the affected area and supporting a gradual return to activity where appropriate. Some sports injuries can be managed without surgery; others may require an operation.
Tendon and Ligament Problems
Tendons and ligaments can be injured through a sudden force or repeated stress. A tendon may become irritated, damaged or torn. A ligament may stretch or tear, affecting the stability of a joint.
The level of impairment can vary. Assessment may include examining movement and stability, considering how the injury occurred and reviewing imaging results. Treatment options depend on the affected tissue, the extent of injury and the person’s needs.
Spinal Conditions
Orthopaedics includes conditions affecting the spine, which is made up of bones called vertebrae as well as discs, joints, ligaments, muscles and nerves. Some orthopaedic specialists focus on the spine.
Spinal conditions may involve back or neck pain, changes to the discs, narrowing around nerves, fractures or spinal alignment. Some concerns are assessed and managed without surgery, while others may require a specialist procedure. The source of symptoms and the effect on a person’s function are important considerations.
Paediatric Orthopaedics
Paediatric orthopaedics focuses on musculoskeletal conditions in babies, children and teenagers. Children’s bones and joints are still growing, so assessment and treatment may differ from care for adults.
Conditions may include fractures, limb or foot problems, differences in bone development, spinal curvature and conditions present from birth. Paediatric orthopaedic specialists take a child’s growth and development into account when considering care.
Hand and Upper Limb Conditions
Some orthopaedic specialists focus on the hand, wrist, elbow and shoulder. These areas contain many small bones, joints, tendons and nerves that work together to support movement and grip.
Concerns may include fractures, tendon injuries, nerve compression, arthritis or problems affecting the shoulder. The specialist may consider how the condition affects tasks such as writing, lifting, dressing or using tools.
Foot and Ankle Conditions
Foot and ankle orthopaedics addresses problems affecting the bones, joints and soft tissues of the lower leg and foot. These structures support body weight and help with standing and walking.
A specialist may assess injuries, joint conditions, tendon problems, deformities or pain that affects mobility. Care depends on the cause and severity of the problem, as well as the person’s daily activities.
How an Orthopaedic Assessment Works
An orthopaedic assessment typically begins with questions about the concern. The clinician may ask when it started, whether it followed an injury, how it has changed and which activities are affected. They may also ask about previous injuries, medical conditions, work or sport, and any treatments already tried.
The physical examination may include checking the affected area, movement, strength, joint stability, sensation and circulation. The specific checks depend on the body part and the symptoms. A clinician may compare the affected side with the other side, when appropriate.
The specialist will explain what the findings suggest and whether further tests are needed. Sometimes a diagnosis can be made from the history and examination. In other situations, imaging or laboratory tests may help clarify the cause.
Common Orthopaedic Tests
X-rays
X-rays create images of bones and are often used to assess fractures, joint alignment and some bone changes. They do not show every type of soft-tissue injury, but they can provide useful information about the bones and joints.
Magnetic Resonance Imaging
Magnetic resonance imaging, or MRI, uses a magnetic field and radio waves to create detailed images of soft tissues and bones. It may be considered when a clinician needs more information about structures such as ligaments, cartilage, muscles, tendons or discs.
Computed Tomography
Computed tomography, or CT, uses X-rays taken from different angles to produce detailed images. It can be useful for assessing complex fractures and certain bone or joint problems.
Ultrasound
Ultrasound uses sound waves to create images. It can help assess some tendons, muscles and other soft tissues, and may be used to guide certain procedures.
Other Assessments
Depending on the concern, a clinician may recommend blood tests, nerve studies or other investigations. Not every person needs every type of test. The choice depends on the clinical question and the information already available.
Non-Surgical Orthopaedic Care
Many musculoskeletal conditions can be managed without surgery. Non-surgical care may be considered alone or before an operation, depending on the condition. Options can include changes to activity, physiotherapy, supportive devices, medication or injections. These are examples of approaches that a clinician may discuss; they are not suitable for every person or every condition.
Physiotherapy may help improve movement, strength, balance or function after an injury or operation. A physiotherapist can assess the person’s needs and design a programme within their scope of practice. Orthopaedic specialists may coordinate with physiotherapists and other healthcare professionals as part of a broader care plan.
Supportive devices can include braces, splints, casts, walking aids or orthotics. Their purpose and duration of use vary. A clinician or therapist can explain how a device is intended to be used and when it should be reviewed.
Orthopaedic Surgery
Surgery may be considered when an operation is likely to help address a specific problem and non-surgical options are not suitable or have not provided sufficient benefit. It is not automatically required for every orthopaedic condition.
Examples of orthopaedic procedures include:
- Fracture fixation, using devices such as plates, screws or rods to stabilise a broken bone
- Arthroscopy, using a small camera and instruments to examine or treat some joint problems
- Joint replacement, replacing a damaged joint surface with an artificial implant
- Ligament reconstruction, rebuilding or repairing a damaged ligament in selected cases
- Spinal procedures, performed for certain conditions affecting the spine
- Tendon or soft-tissue repair, used for particular injuries
Every operation has possible benefits, risks and recovery needs. The surgeon explains what the procedure involves and discusses alternatives, expected recovery and follow-up. The decision is made with the patient, taking account of the diagnosis, overall health and personal priorities.
Recovery and Rehabilitation
Recovery after an injury or procedure can take time. The length and type of recovery depend on the condition, treatment, the person’s health and the demands of their daily activities. Some people need temporary support or changes to their routine. Others require a longer rehabilitation programme.
Rehabilitation may involve physiotherapy, occupational therapy or other support. The purpose is to help restore or maintain function and support a safe return to activities. Recovery plans are individual, and progress may not be identical from one person to another.
Follow-up appointments allow the healthcare team to check healing, review symptoms and adjust the plan if needed. Patients can ask the treating team what activities are suitable during recovery and when they should seek further assessment if concerns arise.
Orthopaedic Subspecialties
Orthopaedics includes several areas of additional expertise. A specialist may focus on:
- Sports medicine, including sports-related injuries and return-to-activity planning
- Spine surgery, involving selected conditions of the neck and back
- Joint replacement, often focusing on hip or knee surgery
- Hand and upper limb surgery
- Foot and ankle surgery
- Paediatric orthopaedics
- Trauma orthopaedics, which focuses on serious injuries, including complex fractures
- Orthopaedic oncology, which assesses tumours affecting bones and soft tissues
Subspecialties can overlap. A person with a complex injury may be seen by more than one specialist, along with rehabilitation professionals.
Orthopaedics and Related Professions
Orthopaedic care is often provided by a team. An orthopaedic surgeon diagnoses and manages musculoskeletal conditions and performs surgery when appropriate. A physiotherapist works on movement and function within their professional scope. An occupational therapist may support daily activities and recommend practical adaptations. Nurses, radiographers, pain specialists and rehabilitation professionals may also contribute.
These roles are different but complementary. The care team involved depends on the person’s needs and local services. A general practitioner or family doctor may also be involved, particularly in the early assessment of a concern or in ongoing care.
Orthopaedics and Everyday Function
Orthopaedic problems can affect activities that people may otherwise take for granted, such as walking, climbing stairs, reaching overhead, carrying items or taking part in sport. The effect can differ considerably. One person may have mild discomfort that rarely interrupts daily life, while another may have significant difficulty with movement or work.
For this reason, an orthopaedic assessment often considers function as well as images or test results. A clinician may ask what the person wants to be able to do and which activities are most important to them. These details help shape discussions about possible treatment and recovery goals.
