Orthopaedics
Orthopaedic surgery is the branch of surgery that deals with disorders of musculoskeletal system including acute, chronic and traumatic injuries. These musculoskeletal ailments also include arthritis and other congenital deformities which are addressed by surgical and non surgical methods.

Orthopaedic surgery provides a broad range of services, all related to the body's bones, joints, and muscles. Primarily it address injuries, and diseases affecting the limbs, including the leg, hip, knee, ankle, foot, shoulder, elbow, wrist, hand, and spine.
Orthopedic surgery or orthopedics (also spelled orthopaedics) is the branch of surgery concerned with conditions involving the musculoskeletal system. Orthopedic surgeons use both surgical and non-surgical means to treat musculoskeletal trauma, sports injuries, degenerative diseases, infections, tumors, and congenital conditions.
    In recent years, surface replacement of joints, in particular the hip joint, have become more popular amongst younger and more active patients. This type of operation delays the need for the more traditional and less bone-conserving total hip replacement, but carries significant risks of early failure from fracture and bone death.
    One of the main problems with joint replacements is wear of the bearing surfaces of components. This can lead to damage to surrounding bone and contribute to eventual failure of the implant. Use of alternative bearing surfaces has increased in recent years, particularly in younger patients, in an attempt to improve the wear characteristics of joint replacement components. These include ceramics and all-metal implants (as opposed to the original metal-on-plastic). The plastic (actually ultra high molecular weight polyethylene) can also be altered in ways that may improve wear characteristics.

the top 25 most common procedures (in order) performed by orthopedic surgeons are as follows:

• Knee arthroscopy and meniscectomy
• Shoulder arthroscopy and decompression
• Carpal tunnel release
• Knee arthroscopy and chondroplasty

• Knee arthroscopy and anterior cruciate ligament reconstruction
• Knee replacement
• Repair of femoral neck fracture
• Repair of trochanteric fracture
• Debridement of skin/muscle/bone/fracture
• Knee arthroscopy repair of both menisci
• Hip replacement
• Shoulder arthroscopy/distal clavicle excision
• Repair of rotator cuff tendon
• Repair fracture of radius (bone)/ulna
• Laminectomy
• Repair of ankle fracture (bimalleolar type)
• Shoulder arthroscopy and débridement
