Orthopedic surgery or orthopedics (alternatively spelled orthopaedic surgery and orthopaedics) is the branch of surgery concerned with conditions involving the musculoskeletal system.

Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors, and congenital disorders.

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease.

MRI scanners use strong magnetic fields, radio waves, and field gradients to generate images of the inside of the body.

Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing.

Ultrasound is no different from 'normal' (audible) sound in its physical properties, except in that humans cannot hear it.

This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy, young adults.

Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz.

Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant.

Hip replacement surgery can be performed as a total replacement or a hemi (half) replacement.

Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures.

A total hip replacement (total hip arthroplasty) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head.

Hip replacement is currently the most common orthopaedic operation, though patient satisfaction short- and long-term varies widely.

The average cost of a total hip replacement in 2012 was $40,364 in the United States, and about $7,700 to $12,000 in most European countries.
