Guidelines for the Diagnosis and Treatment of Ulnar Impaction Syndrome (2024)

Abstract

Abstract Background: Ulnar impaction syndrome (UIS), also known as ulnar impaction or ulnar abutment, is a degenerative condition causing pain on the ulnar side of the wrist. It can lead to wrist bone necrosis, resulting in wrist joint stability disruption and a significant wrist function impairment. The global understanding of this condition varies, contributing to substantial differences in clinical outcomes. Purposes: This paper underscores the necessity of developing evidence-based clinical guidelines for UIS to guide clinicians in their diagnostic and therapeutic approaches. Methods: In collaboration with the Asian Pacific Wrist Association, a team of experts from various fields within the Hand Surgery Department at Huashan Hospital has collectively formulated the “Clinical Practice Guidelines for Ulnar Impaction Syndrome (2024)” (hereinafter referred to as the “Guidelines”). The development process adhered to the guidelines outlined in the World Health Organization's handbook for guideline development. Results: Ten key questions and 21 recommendations are formed. The Guidelines provide recommendations for UIS diagnosis, criteria for selecting conservative or surgical interventions, options for surgical procedures, and address various related issues. Conclusions: The collaborative effort aims to standardize clinical practices, enhance diagnostic accuracy, and improve treatment outcomes for individuals affected by UIS, with these recommendations intended to serve as a valuable reference for healthcare professionals.
