Purpose: Arthrodesis of distal interphalangeal (DIP) and thumb interphalangeal (IP) joints is a well-established procedure for the treatment of pain, deformity, and instability associated with arthritis and traumatic conditions. Fixation with various headless compression screws has become increasingly common and with favorable outcomes. However, there are still characteristic complications, such as hardware prominence with the distal end of the screw incompletely buried in the distal phalanx. The purpose of this study was to review the outcomes and complications associated with the arthrodesis of DIP and thumb IP joints using the Reverse Fix Nail (Tact Medical, Inc., Tokyo, Japan), a headless compression screw designed for DIP and thumb IP joint arthrodesis.

Methods: We retrospectively reviewed 89 cases involving 60 patients, in which arthrodesis with the Reverse Fix Nail was performed for DIP and thumb IP joints. We referenced medical charts, radiographs, and operative records to investigate the complications and postoperative periods to bone union.

Results: Of the 89 consecutive cases, 86 (97%) achieved bone union. Complications included 1 case of prominent hardware and 3 cases of nonunion (1 was asymptomatic and the other 2 were symptomatic, requiring secondary surgery).

Conclusions: The Reverse Fix Nail is a favorable implant for DIP joint or thumb IP joint arthrodesis with a comparable bone union rate and lower risk of hardware prominence than other implants.
