Conservative Joint Use. Use joints in a manner that produces the least amount of stress on them, such as using larger, stronger joints in place of smaller ones whenever possible. For example, use a shoulder bag rather than a hand-held purse. An occupational therapist can help you select devices that are appropriate for your condition. Splinting Your physician may recommend splinting to help with inflammation or problems with joint alignment or stability.
Splints also can help minimize joint destruction.
Wrist or finger splints may help rest joints at night or hold them in a comfortable position during work or exercise. However, joints should not be totally immobilized. Surgery Most people with psoriatic arthritis will never need surgery. However, when all other treatments fail, a surgical procedure called synovectomy may be required to restore joint function or remove diseased portions of the joints. Severely damaged joints may require arthroplasty or joint replacement surgery, in which natural joints are replaced with synthetic ones to restore function in the affected area.
