Abstract
The authors implanted 22 pyrolytic carbon replacements of the proximal interphalangeal joint in 16 patients in the period from 2009 to 2011. All patients were assessed both clinically and radiologically 3, 6 and 12 months after the surgery.
Patient satisfaction, range of movement, stability and implant integration were evaluated. Results: 14 patients were relived of pain completely, all of the joints were stable.
From the objective point of view, the PIP joint function improved in 14 patients. The range of movement was improved in 13 patients.
The mean range of movement after the surgery was 65 degrees ranging from 0 to 85 degrees. The mean deficit of extension was 14 degrees.
The authors did not encounter any widening of radiolucent lines on radiographs.
