[Modified volar plate arthroplasty for posttraumatic and idiopathic osteoarthritis of the metacarpophalangeal and proximal interphalangeal joints].
This article presents the results of modified resectional arthroplasty with interposition of the proximally based palmar plate and economic partial resection of the proximal joint surface without cutting the collateral ligaments. Indications were posttraumatic, idiopathic, and tumorous arthrosis of the metacarpophalangeal (MP) and proximal interphalangeal (PIP) joints.In MP joints, the range of motion improved in eight patients from 40 degrees to a median of 70 degrees with an extension deficit of 10 degrees and a pinch strength of 4.5 kg. All patients (n=8) were free of complaints at a DASH level of 8. In PIP joints, the range of motion improved from 40 degrees to 60 degrees after 35 months in 12 patients with dynamic postoperative treatment. All patients except one were pain-free at a DASH level of 27. Postoperative dynamic splinting was superior to static care.
