Cannulated screws versus K-wires for fixing distal radius (wrist) fractures
Official title: A Comparative Study Between Cannulated Screws and K-wires in the Treatment of Distal Radius Fractures
Run by Sohag University · NCT07523386 · Data updated 2026-11-12
This study will test whether cannulated screws or K-wires lead to better arm function and fewer complications in adults (18–60) with displaced extra-articular distal radius fractures.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–60 with displaced or unstable extra‑articular distal radius fractures who are fit for surgery and willing to follow up are ideal candidates.
✕Probably not a fit
Patients with open fractures, pathological fractures, prior wrist fractures or surgery, associated neurovascular injury, polytrauma, or severe osteoporosis/systemic conditions affecting bone healing are excluded and unlikely to benefit from this comparison.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a prospective, two-group comparative study that assigns adults with displaced extra‑articular distal radius fractures to fixation with either cannulated screws or K-wires. Participants will undergo the assigned minimally invasive fixation and be followed for 6 months postoperatively. The primary outcome is wrist function measured by the DASH score at 6 months, with secondary outcomes including radiographic alignment (radial height, inclination, volar tilt), time to union, and complication rates. The goal is to directly compare clinical and radiological recovery between the two commonly used fixation methods.
Why it matters
Potential benefit: If successful, the results could identify which fixation method gives better wrist function and fewer complications, helping surgeons choose the preferred technique for selected fractures.
How similar studies have gone: Prior small studies and case series have reported comparable outcomes for minimally invasive cannulated screw fixation and K-wires in selected extra‑articular fractures, but robust comparative data are limited.
