Intramedullary Screw vs. K-wire Fixation for Broken Finger
(HANDFIX Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines two surgical methods for fixing broken fingers: intramedullary screws and K-wires (Kirschner wires). The goal is to determine which method enables faster return to daily activities and better hand function. Screws may allow quicker movement, while K-wires require the hand to remain still longer. Ideal participants are adults needing surgery for specific finger fractures who can attend follow-up appointments for 3 months. As an unphased trial, participants contribute to valuable research that may enhance surgical outcomes for future patients.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that these methods are safe for fixing broken fingers?
Research has shown that using intramedullary screws to fix broken fingers is generally safe. In one study, only 4.4% of cases experienced major problems. Most patients expressed satisfaction with the treatment, with 94.6% stating they would choose it again. The main issues include the screw protruding, bones shifting, and infections, though these are uncommon.
The Kirschner wire (K-wire) procedure is also considered safe but carries some risks. Patients might need to keep their hand still for an extended period, and there is a chance of bones healing incorrectly or infections at the wire entry site.
Overall, both methods are well-tolerated, each with distinct pros and cons.12345Why are researchers excited about this trial's treatments?
The intramedullary screw is unique because it offers a minimally invasive way to fix broken fingers with rigid support, acting like an internal splint. This technique allows patients to start moving their fingers sooner without the typical risks that come with more invasive surgery. Researchers are excited about this approach because it could reduce the need for prolonged immobilization and lower the chances of complications, like infections, compared to the traditional Kirschner wire method.
What evidence suggests that this trial's treatments could be effective for broken fingers?
This trial will compare two methods for treating broken fingers: intramedullary screw fixation and Kirschner wire (K-wire) fixation. Studies have shown that using a small screw inside the bone effectively treats broken fingers. This method provides stable support for the healing bone with minimal cutting, often resulting in good hand function and a quicker return to normal activities. Patients report high satisfaction and a low rate of complications, such as infections. In comparison, K-wire fixation is also minimally invasive but usually requires the hand to remain still for a longer period, which can increase the risk of complications.16789
Are You a Good Fit for This Trial?
This trial is for adults over 18 with a closed fracture in the upper or middle part of their finger, who are scheduled for surgery at the investigators' hospital. Participants must be able to give informed consent and fill out health questionnaires in English.Inclusion Criteria

Trial Overview
The study compares two surgical methods for fixing broken fingers: using an intramedullary screw (a newer method that requires minimal cutting) versus a Kirschner wire (pins requiring little to no cutting but immobilization after). It aims to see which leads to better hand function, satisfaction, and faster return to work.

Experimental Treatment
Active Control
Intramedullary (IM) screw fixation is a minimally invasive technique that provides rigid fixation of fractures, acting as an internal splint and load-sharing device. IM screw fixation may allow for early mobilization without the operative site morbidity of open reduction and its associated complications.
Kirschner wire (K-wire) fixation is a minimally invasive technique that provides non-rigid fixation of fractures. K-wires allow for fracture fixation with minimal soft tissue injury and preserved blood supply. However, patients require prolonged postoperative immobilization and are at risk of malunion and pin tract infection.
