title: Pisotriquetral arthrodesis for pisotriquetral instability: case report.
abstract: A 22-year-old professional downhill mountain bike rider developed increasing posttraumatic pisotriquetral instability. To preserve full function of the pisiform bone, we performed pisotriquetral arthrodesis using a Herbert screw. Ten months after the splint was removed, the patient was free of symptoms and returned to professional downhill mountain biking without limitations. This uncommon method seems to be a feasible treatment strategy and can be recommended in high-demand patients.
