Abstract :
Objective: To establish the association between initial and residual
angulation of the distal interphalangeal joint (DIJ) in mallet finger
treated conservatively. Methods: An observational, prospective,
descriptive and analytical research developed with uncomplicated
closed mallet finger patients between January and December 2017.
A total of two measurements of the DIJ were done, at the initial trauma
and 6 weeks after conservative treatment. All measurements were
ranked according to the Crawford Classification and Relative Risk
was measured. Results: In total, 43 patients were studied, in which
53.48% of outcomes obtained were excellent. The sample was
divided in two groups; one with less than 30º of DIJ initial angulation,
which had 28% of residual angulation. The second group with more
than 30º presented 72.22% of residual angulation. The Relative
Risk to present a residual angulation in patients that had 30º of DIJ
initial angulation was 2.99 (CI 95%) with p = 0.0059. Conclusion: It
is suggested that patients with an initial DIJ angulation more than
30º are more likely to present residual angulation with conservative
treatment. Level of Evidence IV, Case series.
