Comparative Study Between Cannulated Screws and K-wires in the Fixation of Distal Radius Fractures

April 15, 2026 updated by: Ahmed Mahmoud Tammam, Sohag University

A Comparative Study Between Cannulated Screws and K-wires in the Treatment of Distal Radius Fractures

This comparative study aims to evaluate the clinical and radiological outcomes of cannulated screw fixation versus K-wire fixation in the treatment of distal radius fractures. Adult patients with distal radius fractures will be allocated to either cannulated screw fixation or K-wire fixation. The primary outcome measure will be functional outcome assessed using the DASH score, with secondary outcomes including radiographic parameters and complication rates.

Detailed Description

Distal radius fractures are among the most common orthopedic injuries in adults. Various fixation techniques are used depending on fracture pattern and surgeon preference. Cannulated screw fixation and K-wire fixation are minimally invasive techniques commonly used in selected fracture types; however, there is ongoing debate regarding their comparative effectiveness in terms of functional recovery and complication rates.

This prospective comparative study will include patients diagnosed with distal radius fractures who meet the inclusion criteria. Participants will be allocated into two groups: Group A will undergo fixation using cannulated screws, and Group B will undergo fixation using K-wires. Patients will be followed for a period of 6 months postoperatively.

The primary outcome will be functional assessment using the DASH score at 6 months. Secondary outcomes will include radiographic parameters (radial height, radial inclination, and volar tilt), time to union, and postoperative complications.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Cannulated Screw Fixation

Arm 1: Cannulated Screw Fixation

Description:

Patients in this group will undergo surgical fixation of distal radius fractures using cannulated screws. Postoperative functional outcomes will be assessed using the DASH score at 6 months. Radiographic alignment (radial height, radial inclination, and volar tilt) and complication rates will also be recorded
Procedure: Cannulated screw Fixation In Treatment Of Distal Radius
Patients assigned to this group will undergo surgical fixation of distal radius fractures using cannulated screws. The procedure involves open reduction and internal fixation with appropriate screw placement under fluoroscopic guidance. Postoperative care includes standard immobilization, physiotherapy, and follow-up visits to assess functional recovery using the DASH score and radiographic alignment. Complications such as infection, malunion, or hardware failure will be monitored.
No Intervention: K-wire fixation
Patients in this group will undergo surgical fixation of distal radius fractures using percutaneous K-wires. The procedure involves closed reduction followed by insertion of K-wires under fluoroscopic guidance. Postoperative care includes immobilization and physiotherapy. Functional outcomes will be assessed using the DASH score at 6 months, and radiographic alignment and complication rates will be monitored.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
