Abstract

Background The purpose of this study is to evaluate outcomes (report union rates and times based on CT) for subacute scaphoid fractures, defined as those presenting between 6 weeks and 6 months from injury.

Questions 1) What are the expected union rates for subacute scaphoid fractures? 2) What are the expected union times for subacute scaphoid fractures? 3) Is it worth trialing a period of cast immobilization for these patients?

Methods All isolated sub-acute scaphoid fractures that presented at our institution between 2006 and 2010 were identified. Each subject's health record, CT scans and X-rays were retrospectively reviewed.

Results There were 20 males and 8 females, with a mean age of 30, treated with casting alone. There were 20 waist, 7 proximal and 1 distal pole fracture. The mean casting time was 11 (waist) and 14 (proximal pole) weeks with a union rate of 82% (23/28). Diabetes, comminution and a humpback deformity increased the non-union risk in this cohort. Exclusion of these cases resulted in a 96% union rate (23/24).

Conclusion Subacute scaphoid fractures (presenting within 6 months from injury) can be expected to successfully heal with casting alone, even if the initial diagnosis is delayed. The expected time frame for union with cast treatment is shorter than previously reported.

Level of Evidence IV.
