We treated 31 patients (31 fingers), 12 with volar buttress plating and 19 with dynamic external fixation. Follow-up averaged 35 and 40\u00a0months in the two groups, with a minimal 6-month follow-up. Average active flexion of the proximal interphalangeal joint was 95\u00b0 after plate fixation and 87\u00b0 after external fixation, with an active extension lag of \u20136\u00b0 and \u20139\u00b0, respectively. Active flexion at the distal interphalangeal joint averaged 67\u00b0 in the plate group and 58\u00b0 in the external fixation group, with active extension lags of 0\u00b0 and \u20135\u00b0, respectively. We conclude that both methods can obtain a good range of motion at the proximal interphalangeal joint. A limitation of the extension of the distal interphalangeal joint occurred with dynamic external fixation but not with volar buttress plating.<\/jats:p>\n                  <jats:p>Level of evidence:
