title: Clinical comparison of hook plate fixation versus extension block pinning for bony mallet finger: a retrospective comparison study.
abstract: The aim of this retrospective study was to determine whether traumatic mallet fractures had better outcomes when treated by hook plate fixation (13 patients) or extension block pinning (19 patients). We assessed outcomes using Crawford's criteria; distal interphalangeal joint range of motion; the DASH score; and a visual analogue scale score for pain. We measured radiological parameters. No significant differences were observed in functional and clinical outcomes and in complications. Whereas the operative time was longer in the hook plate group, intraoperative fluoroscopy use, time to bone union and time to return to work were greater in the extension block group. Although the hook plate method is more technically demanding, it provides good stable reduction, earlier mobilization and an earlier return to work. The extension block pinning technique is easier and as effective but it requires greater peri-operative fluoroscopy. Level of evidence: Level III.
