Choosing the proper implant for extra-articular fractures of proximal phalanges: A study on 75 cases.

INTRODUCTION

Phalangeal fractures are the most common fractures of the hand and in particular the proximal phalanx of the long fingers is the most involved. These fractures can ben conservatively managed but, when the fracture pattern is considered unstable, surgical treatment is recommended. However, there is no consensus in literature about the proper surgical option for extra-articular proximal phalanx fractures.

MATERIAL AND

METHODS

We compared clinical and radiographical results after treatment of 75 cases of extra-articular proximal phalanx fractures using three different surgical techniques: closed reduction and internal fixation (CRIF) with Kirschner wires (G1 group), open reduction internal fixation (ORIF) with plates and screws or lag screws (G2 group), and closed reduction and intramedullary screw fixation (CRIMEF)(G3 group).

RESULTS

We found no significant differences in term of union rate and time to fracture healing between the three groups. However, we found a significant reduction in time to return at work and in TAM at the final follow-up examination in G3 group (treated with CRIMEF) when compared with both G1 and G2. No differences in complications rate were found between three groups.

DISCUSSION: The surgical variability in the management of extra-articular phalanx fractures create lacks on standard guide for treatment.

CONCLUSIONS

In conclusion, our results showed good clinical and radiographical results with all the three surgical options. However, the closed reduction and internal fixation with intramedullary screws (CRIMEF) seems to be better in terms of time to return to work and TAM at the final follow-up, probably due to good primary stability and little risk of soft tissue adherence development.
