Wrist Joint Replacement

Wrist replacement is ideal for low-demand patients (rheumatoid arthritis, elderly, bilateral disease) who value motion preservation for daily activities such as eating, typing, and personal care. Wrist fusion is preferred for younger, active patients, manual laborers, or those needing maximum grip strength and durability. Fusion provides a pain-free, stable wrist but eliminates flexion/extension motion. Your surgeon will recommend the appropriate option based on your specific condition and activity requirements. Individual outcomes may vary.

Typical range of motion after total wrist arthroplasty includes 30-40° of flexion and 30-40° of extension (total arc 60-80°). This is less than a normal wrist (140° total arc) but sufficient for most daily activities and significantly better than wrist fusion (0° motion). Grip strength is typically 60-80% of the opposite side. Individual results depend on pre-operative condition, implant type, and rehabilitation compliance.

Current generation wrist implants show 80-90% survival at 10 years based on published studies. This is shorter than hip/knee replacements due to the wrist's complex biomechanics and high demands on small components. Fourth-generation implants show 92-96% survival at 5 years and 70-86% at 10 years depending on implant type. If the implant fails, conversion to wrist fusion is possible with generally good outcomes. Individual implant longevity depends on activity level, implant type, and compliance with restrictions.

You should avoid heavy lifting (greater than 5-10 lbs repeatedly), push-ups, impact activities, using the hand as a hammer, repetitive forceful gripping, and contact sports. The wrist prosthesis is designed for light to moderate daily activities only. Overloading the implant accelerates wear and loosening. Your surgeon will provide specific activity guidelines based on your individual case.

Yes, bilateral wrist replacement is possible and particularly beneficial for rheumatoid arthritis patients with bilateral disease. Surgeries are typically staged (one wrist at a time, 3-6 months apart) to allow recovery of hand function before operating on the other side. Bilateral replacement preserves motion in both wrists, which is especially important for activities like eating and personal hygiene. Your surgical team will determine the appropriate timing for staged procedures.

You may fly with your cast or splint in place. For comfort, an aisle seat is recommended. A minimum stay of 2-3 weeks in Thailand is recommended for initial recovery, cast changes, and follow-up appointments including suture removal at approximately 2 weeks. Upper extremity surgery allows mobility for walking and sightseeing after the first week. Individual timelines may vary based on surgeon assessment.

A minimum stay of 2-3 weeks is recommended, comprising 2-3 days for pre-operative consultation and in-person evaluation, 1-2 nights hospitalized, and approximately 2 weeks for follow-up appointments, suture removal, and initial recovery monitoring. Upper extremity surgery allows for light tourism activities after the first week while keeping the hand elevated during long periods of sitting. Detailed surgical reports and imaging will be provided for your home physician.

Thai hospitals offer latest-generation wrist implant systems including Maestro, Universal 2, and RE-MOTION from major manufacturers. Options include total wrist arthroplasty, partial wrist replacement (radiolunate, radioscapholunate), hemiarthroplasty, and convertible systems. Both cementless press-fit and cemented fixation are available. 3D-printed custom components are available for complex bone loss cases. Your surgeon will recommend the appropriate implant based on your specific condition and bone quality.
