The authors conducted a systematic review to determine if there is scientifically valid (level I or II) evidence for the effect of early motion (< 21 days) of joints surrounding an extraarticular hand fracture on fracture healing or functional outcomes. Two reviewers independently evaluated for study inclusion, trial quality and internal validity. Six poor-quality, quasirandomized studies (level III evidence) involving 459 patients were included. Findings suggest that in simple, closed metacarpal fractures, early motion (EM) has the potential to: (1) result in earlier recovery of mobility and strength, (2) facilitate an earlier return to work, and (3) not affect fracture alignment. Findings also indicate that skin pressure problems are not associated with custom-molded metacarpal fracture braces. The scientific validity of EM interventions after an extraarticular hand fracture has not been established in well-conducted, randomized, controlled trials (level I or II evidence). Current evidence does not support or refute the use of EM after an extraarticular hand fracture. However, further investigations are warranted, as findings to date show a consistent potential for benefit with no significant risk of harm when early regional joint motions are incorporated into the management of closed, extraarticular, finger metacarpal fractures.
