[Swanson double-stem silicone implant arthroplasty of first metatarsophalangeal point].
OBJECTIVE
To evaluate the curative effectiveness of Swanson double-stem silicone implant arthroplasty on the reconstruction of first metatarsophalangeal joint.


METHODS
Swanson double-stem silicone implant arthroplasty was performed on 10 patients, 2 males and 8 females, aged 60 (57-75), suffering from diseases of first metatarsophalangeal joint with 13 diseased joints, including hallux valgus with geriatric osteoarthritis (8 cases, 10 joints), rheumatoid arthritis (1 case, 2 joints), and traumatic arthritis (1 case, 1 joint). All patients were followed up for an average of 25 months (12-38 months).


RESULTS
Eight patients felt complete satisfaction with the operation, 1 patient showed satisfaction to some extent, and 1 patient was not satisfied because of pain of the first matatarsophalangeal joint due to severe hyperosteogeny surrounding the cut bone face 3 years after the operation. Osteolysis around the silicone implant occurred in 2 cases without clinical symptoms, and no special treatment was given.


CONCLUSIONS
With the advantages of alleviating pain, preserving the length and alignment of great toe, improving the function of walking, and correcting the deformity, Swanson double-stem silicone implant arthroplasty is effective on reconstruction of the first metatarsophalangeal joint.
