Objectives/Interrogation: Distal interphalangeal joint (DIPJ) arthrodesis can be used to treat pain, deformity, or instability associated with arthritis of DIPJ. It is not common procedure, but effective for creating a painless stable joint. The purpose of this study was to analyze DIPJ pathologies, clinical and functional outcomes of DIPJ arthrodesis with K-wires.

Methods: From April 2010 to December 2017, we retrospectively analyzed 10 patients who underwent DIPJ arthrodesis. Among them, 5 cases were treated for degenerative arthritis, 2 cases for traumatic arthritis, 2 cases for infection and 1 case for congenital synostosis. The mean follow-up period was 14.5 months, with an average age of 57.4 years. Four of the cases were in the fifth finger, 4 cases in the third and 3 cases in the second finger. Arthrodesis was done with K-wires except 1 case with cannulated headless screw. Plain radiographs were used to assess radiological results. Clinical and functional results were assessed by VAS score, DASH score, fusion angle, pulp and side pinch power, and grip strength.

Results and Conclusions: Radiologically, joint congruency was maintained in all cases. Mean DASH score was 8.5, and VAS score was 1.2. For complications, 1 patient had pin site infection, which was cured after conservative treatment. In an infection case, we did revision surgery for nonunion, and achieved fibrous union. The other cases fused successfully, including 1 fibrous union. Mean pulp and side pinch power were 78.5% and 75.2% of normal side, respectively. Mean grip strength was 82.2% of normal side. When compared fibrous union to bony union cases, mild decrease in pulp and side pinch power of fibrous union group was seen (71.2% and 70.2% VS 78.5% and 75.2%), but grip strength (90.4% VS 92.2%) and DASH score (7.2 VS 8.5) were similar.

In the treatment of DIPJ pain with variable causes such as degenerative, traumatic, infection or congenital deformity, arthrodesis results in satisfactory functional outcome even with fibrous union.
