[Arthrodesis of the ankle under arthroscopy. Apropos of 10 cases reviewed after a year]
1Service de Chirurgie Orthopédique et Traumatologique, Centre hospitalier Lyon-Sud, Pierre-Bénite.
Purpose Of The Study:
The technique, results and indications for arthroscopic ankle fusion are detailed and compared with open technics.
Material And Methods:
10 arthroscopic ankle fusions were performed between 1991 and 1993. This procedure was used in 4 cases of rheumatoid arthritis, 5 cases of osteoarthritis and 1 case of joint destruction consecutive to hemophilia. All patients were followed until fusion with an average follow-up of 12 months. The quality and position of the fusion were analyzed clinically and on radiograms.
Results:
9 patients obtained fusion in a neutral position and were able to walk with normal shoes. The average time to fusion was 14.5 weeks (8 to 40). 1 case failed and required reoperation after 15 months. No local complications were observed.
Discussion:
Arthroscopic ankle fusion is a safe procedure with good results in cases with relatively little deformities. Its main interest lies in the low rate of complications. The technique does not increase the rate of fusion when compared to open technics.
Conclusion:
Arthroscopic fusion is recommended in cases with little to moderate deformities in the presence of poor wound healing factors.
