Objective This study aims to define the indications of APSI and evaluate long-term results. Patients Methods is a monocentric including patients that underwent an arthroplasty scaphoid proximal pole using between 1994 2010. were assessed autoquestionnaires measuring ranges motion, key pinch, grip strength. X-ray views wrist done control mobility implant evolution carpal collapse, if present. Results There 19 included with mean follow-up 11 years. The range motion was 106 degrees (65% contralateral side) in flexion-extension 33 (78% radialulnar deviation. strength 72% side. Mayo score 69/100, QuickDASH 26/100, patient-rated evaluation (PRWE) 25/100. After 10 years, osteoarthritis noted 32% patients. associated decrease height. More specifically, capito-lunate after years two out three concerned 20 follow-up. No diagnosed at radiolunate articulation. Conclusion treatment option enables nonunion advanced collapse (SNAC), scapholunate (SLAC) I or II preserve good functional But this does not prevent natural which clinically well tolerated.
