A randomized clinical trial, with patients treated either by new
2-step orthosis or by the figure-eight-type orthosis with the distal
interphalangeal (DIP) joint extended. PURPOSE OF THE STUDY: To report on our new
orthosis and to evaluate the treatment efficacy of using a
2-step orthosis for
the treatment of a mallet finger of tendinous origin compared with a conventional orthosis. METHODS: Forty-four patients were randomized into the 2-step or conventional orthosis groups. Primary outcomes were active DIP joint flexion and
extensor lag, pain, and the Abouna-Brown criteria. RESULTS: The 2-step orthosis
was associated with a smaller active DIP extensor lag, compared with the
conventional orthosis (-7.5 +/- 4.5 degrees vs -16.4 +/- 6.9 degrees , P = .001),
combined with a significantly higher Abouna-Brown criteria (chi2 = 14.57, P =
.01). No other between-group differences were identified. CONCLUSION: The
therapeutic effectiveness of the 2-step orthosis, over a conventional orthosis,
was supported by a large effect size of the treatment in improving residual
active extensor lag at the DIP and overall Abouna-Brown criteria. Our study thus
suggested that the initial immobilization involved in new 2-step orthosis and is
thus a good immobilization technique
