Treatment of tendinous mallet fingers using a Stack splint versus a dorsal glued splint

The goal of this study was to compare the results of a Stack splint compared to a dorsal glued splint in the treatment of tendinous mallet fingers. Our series included 100 patients, aged 47 years in average, among which 40 are women, with a 9-week follow-up. The first 50 patients (group I) were treated with a dorsal glued splint, and the 50 following patients (group II) were treated with a Stack splint. The average lack of active extension of the distal phalanx was 3.1° in group I and 1.74° in group II. The average pain was rated 0.22/10 in group I and 0.26/10 in group II. There were seven cases of nail dystrophies, 18 cases of macerations and five cases of swan neck deformities in group I. There were six cases of macerations and four cases of swan neck deformities in group II. The dorsal nail-glued splint gives comparable results to the Stack splint with the added advantage of leaving the fingertip free.
