Current status of wrist arthrodesis and wrist arthroplasty.
A variety of techniques are available for reconstruction of the wrist. The efficacy of wrist arthroplasty, however, is met with narrowed indications and does not enjoy the success that total joint replacement in other joints, such as the hip and knee, has enjoyed. With design improvements during the last decade, good short-term results from total wrist arthroplasty can be expected in the low-demand patient with rheumatoid arthritis. Wrist arthrodesis, either pancarpal or limited, is considered the primary surgical alternative in patients with most arthritic conditions of the wrist. The pancarpal arthrodesis is a predictable, durable alternative to a variety of post-traumatic, degenerative, or neoplastic conditions of the wrist; however, some authors report that complications may be prevalent. This procedure also may be modified and applied to the destroyed rheumatoid wrist. Overall, selection of fixation mode depends on bone quality. In an attempt to preserve motion, various limited arthrodeses of the carpus have been described. Although technically demanding, successful results may be expected, especially in conditions of carpal instability. With the current wide array of surgical alternatives, the surgeon must consider each case carefully and select the procedure that best applies to each particular situation. Furthermore, it is extremely important that the surgeon educate the patient on the limitations of each procedure.
