Background: Distal Phalanx (DP) fractures are the most common hand injuries. Bone fixation associated with soft tissue reconstruction, is often required to ensure more effective outcomes. The aim of the present study is to compare functional outcomes of DP fractures surgically treated with crossed manual drilled 23 Gauge needles vs crossed Kirschner-wires (k-wire). Methods: Clinical data included analysis of patient demographics, range of motion (ROM), and complications. Radiographic assessment considered fracture type, location, fracture displacement, and radiographic union. Functional outcomes analysis was performed.The statistical significance was assessed at the level of probability lower than 5%. Results: A total of 60 patients from 2012 to 2015 were retrospectively enrolled and among them 12 patients suffering from diabetes or current smokers. A total of 60 DP fractures were treated, 32 with needles (group A) and 28 with k-wire fixation (group B). Time to union, showed in different time points, was significantly lower in group A (≤ 40 days, p = 0.023*) compared to group B. ROM of the distal interphalangeal joint at six months follow-up was 60° in group A and 40° in group B. A significant improvement was observed (p = 0.001*) in the 23 G needle treated group. Functional outcome analysis showed that VAS was significantly lower in group A compared to group B (p = 0.023*). Conclusion: Our study showed that the 23 G needle yielded satisfactory results in terms of time to union and range of motion compared to k-wire fixation especially for tuft and shaft DP fractures. Therefore, should be a valid alternative to k-wire fixation in selected patients.
