Detailed Description
Distal radius fractures account for 17% of all fractures seen at the emergency department. Fifty percent of these fractures are intra-articular. The past several years an increase in open reposition internal fixation (ORIF) for distal radius fractures has been observed. This technique leads to a quicker resume of function the first 3 to 6 months compared to non-operative treatment. However, some patients continue to have a painful and stiff wrist postoperatively. Arthroscopically assisted removal of intra-articular fracture haematoma and debris may improve the functional outcomes following operative treatment of intra-articular distal radius fractures. Moreover, during arthroscopy the quality of the reduction and the presence of associated ligamentous injuries can be assessed.
To our knowledge, no studies have been carried out to further examine the use of arthroscopy after internal plate fixation to remove fracture haematoma and debris on functional outcomes. Therefore, the purpose of this randomised controlled trial is to determine the difference in functional outcome, assessed with the Patient-Rated Wrist Evaluation (PRWE) score, after internal plate fixation with an additional wrist arthroscopy and conventional fluoroscopically assisted internal plate fixation in adult patients with displaced complete articular distal radius fractures. Secondary, we aim to determine the difference in functional outcomes with the Disability of the Arm, Shoulder and Hand (DASH) score, post-operative pain, range of motion, grip strength, complications, quality of life (SF-36), and cost-effectiveness. Additionally, for patients undergoing additional wrist arthroscopy the quality of reduction, associated ligamentous injuries and cartilage damage will be assessed.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: ORIF
The operation has to be performed within 3 weeks after the initial trauma.
According to the current standard, antibiotic prophylaxis (Cefazoline, 1000 milligram intravenous) will be administered thirty minutes preoperatively.
The distal radius will be approached according to Henry, which beholds an incision between the tendon of the flexor carpi radialis and the arteria radialis.
After the fracture site is exposed, the fracture will be reduced and an appropriate volar locking plate will be positioned.
The type and brand of the plate are at discretion of the treating surgeon.
When a dorsal approach is deemed necessary the distal radius will be approached between the third and fourth dorsal extensor tendon compartments.
To evaluate the quality of articular reduction, fluoroscopic images will be obtained.
Wound closure will be performed using standard techniques.

ACTIVE_COMPARATOR: ORIF with additional wrist arthroscopy
Surgery will be performed by a certified trauma surgeon, with experience in wrist arthroscopy.
A delay of minimal 5 days before performing arthroscopy is mandatory to enable visualisation due to the organisation of the hematoma.
During wrist arthroscopy, the forearm will be positioned upright and in neutral position, the elbow flexed by 90° and axial traction of 4-6 kg will be performed.
Four portal entrees are created by superficial stab incisions and blunt preparation through the joint capsule; one midcarpal radiair and one midcarpal ulnar portal and the 3-4 and 6-R portal.
A shaver is used for removal of fracture haematoma and osteocartilaginous debris.
Cartilage damage will be graded using the Outerbridge classification system.
With the 1 mm hook probe assessment of the quality of reduction and ligamentous injuries (TFCC, scapholunate and lunotriquetral) will be performed.
Wound closure will be performed using standard techniques.

Patient Rated Wrist Evaluation
Time Frame: 3 months
|
The PRWE is a 15-item questionnaire designed to measure wrist pain and disability in activities of daily living.
The PRWE allows patients to rate their levels of wrist pain and disability from 0 to 10, and consists of three subscales: Pain, Function and Cosmetics.
