Comparative Study Between Cannulated Screws and K-wires in the Fixation 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.

About this study

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.

Treatment and study plan

Cannulated screw Fixation In Treatment Of Distal Radius

Procedure

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.

Primary outcomes

  1. 1. Radiological union

    Time frame: 6months postoperatively

    Number of patients achieving complete bone healing as assessed by serial X-rays (presence of bridging callus on 3 out of 4 cortices).

    Unit of Measure: Number of Participants.

  2. Mean Hand Grip Strength

    Time frame: 6months postoperatively

    Measurement of the physical force of the hand using a calibrated Jamar hydraulic hand dynamometer. The average of three successive trials with the affected hand will be recorded.

    Unit of Measure: Kilograms.
