Orthopedic Conditions

Fractures

Fractures are breaks or cracks in bones, commonly caused by trauma or repetitive stress. They can be classified as open (compound) or closed (simple) fractures. Treatment involves immobilization with casts, splints, or surgery for complex fractures.

Arthritis

Arthritis refers to inflammation of joints, causing pain, stiffness, and decreased mobility. Osteoarthritis (wear and tear) and rheumatoid arthritis (autoimmune) are common types. Management includes pain relief, physical therapy, and, in severe cases, joint replacement surgery.

Osteoporosis

Osteoporosis is a condition characterized by weak and brittle bones, making them susceptible to fractures. It is commonly seen in postmenopausal women due to hormonal changes. Treatment involves calcium and vitamin D supplementation, regular weight-bearing exercises, and medications to improve bone density.

Scoliosis

Scoliosis is an abnormal lateral curvature of the spine, often diagnosed during adolescence. Mild cases may require monitoring, while severe cases may require bracing or surgical intervention to correct the curvature.

Tendinitis

Tendinitis refers to inflammation of tendons, commonly caused by repetitive movements or overuse. It commonly affects the shoulder (rotator cuff), elbow (tennis/golfer's elbow), and knee (patellar tendinitis). Treatment includes rest, physical therapy, and anti-inflammatory medications.

Sports Injuries

Sprains and Strains

Sprains involve ligament injuries, while strains involve muscle or tendon injuries. They occur due to sudden twisting or stretching motions. Treatment involves R.I.C.E (rest, ice, compression, elevation) therapy, physical therapy, and sometimes surgical intervention for severe cases.

Dislocations

Dislocations occur when bones in a joint are forced out of their normal positions. Common sites include the shoulder, finger joints, and patella. Treatment involves reduction (putting the joint back in place), immobilization, and rehabilitation.

Ligament Injuries (ACL, PCL, MCL)

Injuries to ligaments, such as the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), or medial collateral ligament (MCL), are common in sports. Treatment may include conservative management (rest, physical therapy) or surgical repair/reconstruction, depending on the severity.

Meniscus Tears

Meniscus tears occur in the knee joint and can result from sudden twisting or degenerative changes. Treatment options include rest, physical therapy, arthroscopic repair, or, in severe cases, partial or total meniscectomy.

Rotator Cuff Injuries

Rotator cuff injuries affect the muscles and tendons around the shoulder joint. They can result from trauma or degeneration. Treatment may involve rest, physical therapy, corticosteroid injections, or surgical repair.

Diagnostic Techniques

X-ray Imaging

X-ray imaging is commonly used to assess bone fractures, joint dislocations, and other bony abnormalities. It provides a quick and cost-effective initial evaluation but may have limitations in diagnosing soft tissue injuries.

Magnetic Resonance Imaging (MRI)

MRI uses magnetic fields and radio waves to create detailed images of soft tissues, such as ligaments, tendons, and cartilage. It is useful for diagnosing sports injuries like ligament tears, meniscus injuries, and rotator cuff
