title: Lunate silicone replacement arthroplasty in Kienböck's disease: a long-term follow-up.
abstract: We report a long-term follow-up (average, 5 years) of 10 patients who had lunate silicone replacement arthroplasty for treatment of Kienböck's disease. Clinical results were assessed on relief of pain, return to normal occupation, and range of motion. At 18- to 20-months follow-up, eight patients had satisfactory results, whereas at final follow-up only five of the patients had satisfactory results. Three of five patients with radiographs averaging 57 months after operation had evidence of particulate synovitis. Contrary to our previous publications on silicone replacement arthroplasty, it was concluded that the success rate for silicone replacement arthroplasty and the incidence of particulate synovitis do not warrant the continued use of silicone replacement arthroplasty as a primary treatment modality for Kienböck's disease.
