Various indications exist for thumb interphalangeal and finger distal
interphalangeal arthrodesis. Various fixation techniques (compression screws,
tension band wiring, K-wires) have been described with fusion rates varying
between 80 and 100%. The objective of this study was to evaluate the outcomes of
interphalangeal arthrodesis using the X-Fuse((R)) intramedullary implant in terms
of fusion rate and fusion position. A continuous series of 38 arthrodesis
procedures was reviewed retrospectively to determine the fusion rate and evaluate
complications linked to this fixation technique. The position of the fused joint
was compared to that obtained at the end of the procedure so as to evaluate the
reliability of implant placement. The fusion rate was 94.8%; two arthrodeses had
to be redone with satisfactory results. A moderate change of less than 10 degrees
in the arthrodesis position between the immediate postoperative period and fusion
was observed in the frontal and sagittal planes that had no clinical
consequences. The fusion rate reported here is similar to the best rates
published with other fusion techniques, and few complications occurred. Use of
this intramedullary implant seems to be a viable alternative to the other techniques.
