We devised a dynamic external fixator device called the Gexfinger<jats:sup>\u00ae<\/jats:sup> that allows greater control of the degree of traction. The aim of this study is to report the mid-term outcomes of this device. <\/jats:p><jats:p> Methods: This is a retrospective study of patients with fracture dislocation of the PIPJ who were treated with the Gexfinger<jats:sup>\u00ae<\/jats:sup> over a 3-year period. Clinical data with regard to the patient, the injury, treatment and period of follow-up were recorded. The outcome measures included time to return to work, arc of motion at the interphalangeal joints, grip strength, visual analogue score (VAS) for pain, patient satisfaction and complications. <\/jats:p><jats:p> Results: We studied 26 patients (17 men and 9 women) with an average age of 38 years. The average articular surface involvement was 56%. The mean period between injury and surgery was 6 days and the frames were maintained for 5.5 weeks on average. The mean follow-up period was 8.5 weeks. All patients returned to work at an average of 7 weeks. The mean arc of motion at the PIPJ and distal interphalangeal joint (DIPJ) were 82\u00b0 and 65\u00b0, respectively and the mean grip strength was 83% of the contralateral side. 22 patients reported no pain at the final follow-up. Fifteen patients were very satisfied, 8 satisfied and 3 unsatisfied. Two patients had stiffness of the PIPJ. <\/jats:p><jats:p> Conclusions: The mid-term outcomes of the Gexfinger<jats:sup>\u00ae<\/jats:sup> are similar to other methods of dynamic traction described in literature. It is modular, easy to assemble and allows a greater control of the degree of traction. In combination with additional screws and\/or K-wires, it has allowed us to treat a wide spectrum of PIPJ fracture dislocations with good outcomes. <\/jats:p><jats:p> Level of Evidence: Level IV
