- Abstract
- Objectives
To analyze the risk factors associated with postoperative flexor tendon rupture, after a volar plate fixation of distal radius fractures.
Design
Retrospective observational case–control study.
Setting
Tertiary Care University Hospital in the Republic of Korea (2009–2020).
Patients
Sixteen referred patients were treated for flexor tendon rupture, following previously performed volar plating of distal radius fractures at other institutions. 16 patients were randomly selected from our database as controls, and were matched based on the Soong grade of the case group.
Intervention
Not applicable.
Main Outcome Measurements
Radial tilt and radial height were measured on anteroposterior radiographs. The volar tilt, tear drop angle, carpal translation, and Soong grade were measured in a lateral view.
Results
Quantitative measurements of the volar tilt, carpal translation, and tear drop angle were positively correlated with the flexor tendon rupture. The mean volar tilt and tear drop angle in the tendon rupture group were significantly smaller than those in the control group. The mean carpal translation in the tendon rupture group was significantly greater than that in the control group.
Conclusions
This study demonstrated that volar tilt, carpal translation, and tear drop angle are significant risk factors for flexor tendon rupture, especially for plates placed at Soong grade 1 or 2. We suggest that the potential for tendon rupture because of incomplete reduction of the distal radius fracture along with implant prominence volar to the watershed line aggravates flexor tendon irritation at the distal edge of the plate because of distorted flexor tendon paths.
Level of Evidence
Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
