[Follow-up result of 14 cases of the first metatarsophalangeal joint arthroplasty with titanium total joint prostheses].

An 8-year follow-up study of 14 cases (22 feet) of titanium total 1st metatarsophalangeal joint arthroplasty with two designs (type I and type II) is reported. The follow-up period average was 5 years with a range of 3 to 8 years. The rate of subjective satisfaction was 72.7% (16/22), the incidence of complications 31.8% (7/22), and the rate of revision 27.3% (6/22). The results implicate that titanium total hallux MTP joint arthroplasty is a suitable procedure for osteoarthritis, rheumatoid arthritis and hallux rigidus of the 1st MTP joint, and that type II prosthesis seems better than type I prosthesis. In addition, prosthetic designing, surgical technique and postoperative complications are also discussed in detail.
