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.
Conclusion: 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.
