59 patients (>18 years of age) who were diagnosed with mallet finger (with or without fracture) and who had undergone continuous splint/cast immobilization and hyper-extension intervention (6-8 weeks), were randomly assigned into 1 of 2 treatment groups to determine the effect of an additional one month of night splinting on extensor lag. Participants either received an additional one month intervention with a night splint following their continuous splinting period or received no additional intervention (control). Results from the study demonstrated that no significant differences existed between the two groups by final follow-up when comparing the final extensor lag, disability, or treatment satisfaction experienced by patients.
