    What is Orthopaedics?
    This is an area that deals with conditions of the musculoskeletal system (disorders of bones and joints of the limbs and spine). The specialty covers a range of different types of conditions starting with congenital (conditions which children are born with) through to degenerative (conditions relating to the wearing out of joints). The field of orthopaedics covers trauma where bones are broken or injuries are sustained to limbs.
    Other conditions that sit under the spectrum of orthopaedics are metabolic conditions, neurological and inflammatory conditions.

    Procedures

    Joint Replacement

    For elderly patients joint replacement surgery is commonly required to treat damaged joints from wearing out, arthritis or other forms of joint disease including rheumatoid arthritis. In these procedures the damaged joint surface is removed and replaced with artificial surfaces normally made from metal (chromium cobalt alloy, titanium), plastic (high density polyethylene) or ceramic which act as alternate bearing surfaces for the damaged joint. These operations are major procedures which require the patient to be in hospital for several days and followed by a significant period of rehabilitation. The hospital has several ways of approaching the procedure for replacement and the specifics for the procedure will be covered at the time of assessment and booking of surgery.   Occasionally blood transfusions are required; if you have some concerns raise this with your surgeon during consultation.

    Osteotomy

    The division of a crooked or bent bone to improve alignment of the limb. These procedures normally involve some form of internal fixation, such as rods or plates, or external fixation which involves external wires and pins to hold the bone. The type of procedure for fixation will be explained when the surgery is planned.

    Arthroscopy (keyhole surgery)

    A large number of orthopaedic procedures on joints are performed using an arthroscope, where a fibre optic telescope is used to look inside the joint. Through this type of keyhole surgery, fine instruments can be introduced through small incisions (portals) to allow surgery to be performed without the need for large cuts. This allows many procedures to be performed as a day stay and allows quicker return to normal function of the joint. Arthroscopic surgery is less painful than open surgery and decreases the risk of healing problems.  Arthroscopy  allows access to parts of the joints which can not be accessed by other types of surgery.

    Soft Tissue (muscles, tendons and ligaments)

    In many cases tendons will be lengthened to improve the muscle balance around a joint or tendons will be transferred to give overall better joint function. This occurs in children with neuromuscular conditions but also applies to a number of other conditions. Most of these procedures involve some sort of splintage after the surgery followed by a period of rehabilitation, normally supervised by a physiotherapist.
