Proximodistal interphalangeal arthrodesis of the little finger: A series of 7 cases.

As an alternative to amputation of the little finger, we report here seven cases of shortening arthrodesis carried out by resecting the middle phalanx and proximodistal interphalangeal (PDIP) arthrodesis. Our cohort consisted of 6 males and 1 female (58years average age), with a stiff little finger secondary to Dupuytren's disease or trauma. All fingers were approached dorsally; after resection of the middle phalanx and decortication of the subchondral bone, fusion of the remaining phalanges was performed using an intramedullary self-breaking screw-pin. At a mean follow-up of 34.9months, pain decreased significantly (1.4/10 versus 5.4/100 preoperatively), the QuickDASH score improved significantly (33/100 versus 51/100 preoperatively) and all the joints had fused. One patient suffered from cold intolerance. PDIP arthrodesis is an alternative salvage procedure to amputation for multioperated stiff little fingers that does not burn any bridges if it fails.
