Scaphoid proximal pole fracture with avascular necrosis is a complex surgical problem. In some cases, it's possible to perform a scaphoid hemiarthroplasty with an adaptative proximal scaphoid implant (APSI), made of pyrocarbon, replacing the necrotic proximal pole. APSI allows an early mobilization of the wrist, an optimal recovery of strength and a rapid return to normal daily and work activities without limitations. This implant delays palliative and more invasive surgical treatments in patients that are generally young with high functional demands. The investigators have performed a long-term follow up (with a mean follow-up of 17 years) of the early cases of APSI implant performed, starting from 1999. Radiographic and clinical strength recovery, along with subjective outcomes, have been shown to be good, with a rapid return to daily and work activities, indicating that APSI implants are a good alternative to traditional and invasive techniques.
