Relationship of Injury Mechanism Energy to Postoperative Wrist Function in Galeazzi Fractures

This study aims to determine the impact of injury mechanism energy level on clinical outcomes following Galeazzi fracture.

A retrospective review was performed on 116 skeletally mature patients treated operatively for Galeazzi fractures between January 2000 and October 2023. Patients were categorized by mechanism of injury into high-energy (HE, n = 92) and low-energy (LE, n = 24) groups. Demographics, fracture characteristics, fixation details, and postoperative outcomes, including wrist and elbow range of motion, complications, radiographic healing time, and reoperations, were collected and compared between groups using standard parametric and nonparametric tests with significance set at P < .05. Normality was assessed using the Shapiro-Wilk test, and Fisher exact test was used for categorical variables with low expected counts.

No differences were observed in body mass index or injury characteristics between groups. The HE group was younger and included a higher proportion of men. Wrist motion was more limited in the HE group across dorsiflexion, palmar flexion, pronation, and supination, and time to radiographic healing was longer compared with the LE group. Elbow motion and rates of nonunion, fracture-related infection, contracture, readmission, and distal radioulnar joint symptoms were similar between groups.

HE Galeazzi fractures were associated with poorer wrist range of motion and toward delayed radiographic healing compared with LE injuries. Recognition of this association underscores the prognostic value of injury mechanism and may inform surgical planning, rehabilitation expectations, and patient counseling.
