Background Isolated scaphotrapeziotrapezoid is a relatively rare condition, and there is still not complete consensus on the treatment of this pathology.

Purpose The aim of the present study is to assess the utility of implant interposition after arthroscopic scaphoid distal pole resection for scaphotrapeziotrapezoid arthritis.

Material and Methods The authors present a prospective study after the arthroscopic resection of the distal pole of the scaphoid in 24 patients. In a group of 11 patients, the simple resection was performed while in the other 13 patients the scaphoid resection and pyrocarbone implant interposition.

Results All patients were clinically evaluated with disability of arm, shoulder, hand score. Dorsal intercalated segment instability deformity was also measured from X-ray analysis. Grip and pinch strength were measured too, and patients were also given a visual analog scale questionnaire. Both clinical and radiographic assessments were done at 24 months postoperatively.

Conclusions The study showed comparable results with both the techniques.

Level of Evidence II A prospective comparative study.


Patients were treated in San Pio X Clinic, Milan, Italy, and Rimini Center for Hand Surgery, Rimini, Italy, as well as data collection. Analysis was performed at San Pio X Clinic, Milan, Italy.
