    Author: Marudanayagam A, Appan SV.
    Journal: J Orthop Surg (Hong Kong); 2014 Apr; 22(1):35-8. PubMed ID: 24781610.
    Abstract:
    PURPOSE: To report the outcome of fusion of the first metatarsophalangeal joint (MTPJ) using the Fyxis plate and compression screws. METHODS: Medical records of 12 men and 39 women (54 feet) aged 28 to 74 (mean, 58) years who underwent primary fusion of the first MTPJ using the Fyxis plate and compression screws for hallux rigidus (n=38), severe hallux valgus (n=8), or rheumatoid arthritis (n=8) were reviewed. The outcome measures included the fusion rate, time to fusion, complication rate, hallux valgus angle, dorsiflexion angle, and the American Orthopaedic Foot and Ankle Society (AOFAS) scale. RESULTS: The mean follow-up was 14.8 (range, 12-20) months. The mean time to fusion was 3.2 months. 48 feet achieved complete fusion at 3 months, 5 at 6 months, and one had non-union at 12 months, which was treated with revision surgery. The mean hallux valgus angle improved from 23º to 12º. The mean dorsiflexion angle improved from 22º to 23º. The mean AOFAS scale score improved from 31 to 86. 98% of the feet achieved a score of >72. One patient with non-union had a score of 59. Two feet developed superficial wound infection, which resolved with antibiotic treatment. Two other feet developed numbness over the medial aspect of the great toe, which persisted after one year. CONCLUSION: The outcome of fusion of the first MTPJ using the Fyxis plate and compression screws was good.
