Repair or Not Repair Pronator Quadratus in the Volar Plating of Distal Radial Fracture Are Functional Outcomes Differ ?
An observational study of Distal Radius Fracture, run by National Taiwan University Hospital.
Trial summary
The theoretical benefits of the repair of the pronator quadratus include flexor tendon protection, remain of the normal pronation-supination range of motion (ROM) and strength, and keeping the stable DRUJ. Read more about this study

About this study
Official title: Repair or Not Repair Pronator Quadratus in the Volar Plating of Distal Radial Fracture-Are Functional Outcomes Differ ?
The theoretical benefits of the repair of the pronator quadratus include flexor tendon protection, remain of the normal pronation-supination range of motion (ROM) and strength, and keeping the stable DRUJ.
Repair or not repair pronator quadratus in the volar plating of distal radial fracture-Are functional outcomes differ?
Read the detailed description
In the operation of distal radial fractures, the volar plating techniques become popular. During the surgical approach, the pronator quadratus (PQ) muscle needs split or full-thickness strip to exposure the fracture site and facilitate the instrumentation of the plate. Generally, the PQ would be repaired. Sometimes, the PQ is damaged by the fracture fragment so severely that it is difficult to repair the PQ. However, there is few reviews paper to discuss the consequence of the unrepaired or repaired PQ and the AAOS guideline1 of the treatment of distal radial fracture in 2009 did not even list the management of the PQ. The function of the PQ includes pronation and stability of the distal radial-ulnar joint (DRUJ). According to the study, the elimination of PQ function will cause a significant decrease in pronation torque, which is supposed to affect the function of the wrist in the daily life. The theoretical benefits of the repair of the pronator quadratus include flexor tendon protection3,4, remain of the normal pronation-supination range of motion (ROM) and strength, and keeping the stable DRUJ.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 May 2012; AzTrials last refreshed its copy on 8 Nov 2026.
