Elbow replacementDefinition: Elbow replacement involves surgically replacing bones that make up the elbow joint with artificial elbow joint parts (prosthetic components). The artificial joint consists of two stems made of high-quality metal. They are joined together with a metal and plastic hinge that allows the artificial elbow joint to bend. The artificial joints come in different sizes to fit the patient.
Alternative Names: Total elbow arthroplasty; Endoprosthetic elbow replacement
Description: The patient may receive general anesthesia (unconscious, no pain) or regional anesthesia that prevents the arm from feeling pain. Patients receiving regional anesthesia are also given medicine to help them relax during the operation. The orthopedic surgeon makes an incision, usually in the back of the upper and lower arm, to expose the elbow joint. The surgeon removes the lower end of the bone in the upper arm (humerus) and the upper end of the large bone in the lower arm (ulna), along with any damaged tissue. The orthopedic surgeon then drills out a portion of the center of the humerus and ulna and inserts one stem of the prosthesis into each bone. Usually, bone cement is used to hold the stems in place. The surgeon then attaches the two stems together with the hinge system. The orthopedic surgeon closes the wound with stictches, applies a bandage, and might place the arm in a splint for stability.
Indications: Elbow replacement surgery can be performed when the patient�s joint has been severely damaged. Causes of damage include:
Risks: Risk for any surgery include: Risks of elbow replacement surgery include: - Nerve damage during surgery
- Blood vessel damage during surgery
- Bone break during surgery
- Dislocation of the artificial joint
- Loosening of the implant over time
- Allergic reaction to the implant
Expectations after surgery: The patient will stay in the hospital for about three or four days. A splint may be used after surgery to help stabilize the elbow.� Elbow replacement surgery relieves pain for most patients.
Convalescence: Physical therapy, starting with gentle flexing exercises, will be prescribed. Patients who have a splint typically start therapy a few weeks later than those who do not. The patient will need help with everyday activities, such as driving, shopping, bathing, meal preparation, and household chores, for up to six weeks. Some patients may begin to regain function of the elbow as soon as 12 weeks after surgery, although additional recovery can take up to a year. The patient should not lift more than five pounds with the operated arm, even when fully recovered.
