Patient-reported physical functioning and pain improve after scaphoid nonunion surgery: A Cohort Study.

Abstract

BACKGROUND\nSince all patients with a scaphoid nonunion are generally treated surgically to prevent progressive osteoarthritis, it is important to set postoperative expectations regarding physical functioning and pain. Previous study mainly focus on postoperative scaphoid union and physician-based outcomes. Therefore we aim to report the change from preoperative to postoperative patient-reported outcomes to inform patients with a scaphoid nonunion about their postoperative expectations.\n\n\nMATERIAL AND METHODS\nData were prospectively collected as part of usual care at the Xpert Clinic in the Netherlands. Adult patients who underwent scaphoid nonunion surgery minimally 3 months after a scaphoid fracture, were eligible for inclusion. Only patients with complete preoperative and postoperative questionnaires regarding our primary outcome (Patient Rated Hand/Wrist Evaluation (PRWHE) were included. As secondary outcomes, we assessed the Visual Analog Scale (VAS) pain and hand function, range of motion of the injured wrist measured by a hand therapist, and patient satisfaction with questionnaires.\n\n\nRESULTS\nWe included 118 patients with complete preoperative and postoperative (11 - 92 months) PRWHE questionnaires. The median PRWHE score improved significantly from 47 [IQR 27 - 62]) preoperative to 11 [IQR 5 - 23] postoperative (p<0.001). Postoperative improvement in pain and physical functioning was also observed in the PWRHE subdomains pain and disability separately (p<0.001), VAS pain, and VAS function (p<0.001). There was no difference between preoperative and postoperative range of motion of the injured wrist. Satisfaction with the hand improved significantly from preoperative to postoperative (p<0.001). Good or excellent satisfaction with the treatment result was reported by 69% of the patients and 86% would undergo the treatment again.\n\n\nCONCLUSIONS\nPatients can expect an improvement in physical functioning and pain after scaphoid nonunion surgery. Most patients are satisfied with the treatment result.
