title: Extension block technique for mallet fractures: a comparison of one and two dorsal pins.
abstract: The aim of this study was to compare the clinical and radiological outcomes of one or two dorsal pins for extension blocking of mallet fractures. We treated 36 mallet fractures with the extension block technique. A single pin was used in 19 fractures (Group 1) and two pins in 17 fractures (Group 2). The mean age was 33.6 years and the mean follow-up time was 12.2 months. All patients were assessed by the Crawford outcome score. Extensor lag and other complications were noted. All fractures united with a mean time of 6.0 weeks (4-9) in Group 1, and 6.1 weeks (4-7) in Group 2. We obtained 74% and 71% excellent and good outcome scores in Group 1 and in Group 2, respectively. The final extension lag was 6° in Group 1, and 7° in Group 2. No difference was found between the two groups in terms of clinical outcomes, radiological values and complications.Level 3 non-randomized controlled study.
