There is no consensus about the best treatment for patients with displaced complete articular distal radius fractures (AO type C fractures). Despite this lack of consensus and the lack of available literature on comparative data to guide treatment for this patient population, operative treatment with plate fixation has gained popularity. The aim of this study is to compare the functional outcome of open reduction and plate fixation with closed reduction and plaster immobilisation in adult patients (18-75 years) with displaced complete articular distal radius fractures.
Distal radius fractures account for 17% of all fractures diagnosed. Two third of those fractures are displaced and need to be reduced.
According to the Dutch National Guidelines, displaced distal radius fractures, after adequate reduction confirmed on X-ray, are best treated nonoperatively with cast immobilization. Moreover, the AAOS Clinical Practice Guideline only suggest surgical fixation when the articular step, after reduction, exceeds 2mm. However, both recommendations are based on studies who did not differentiate between intra- and extra-articular distal radius fractures. So, no clear consensus about the best treatment for patients with displaced intra-articular distal radius fractures can be made. Despite this lack of consensus and the lack of available literature on comparative data to guide treatment for this patient population, a rise in use of volar plating has been observed.
The goal of open reduction and plate fixation is to restore articular congruity and axial alignment, and to enable early post-operative movement. Several studies show good radiological and functional results using the volar locking plate in unstable displaced distal radius fractures.
No studies have been carried out to assess whether operative treatment with plate fixation is superior in displaced complete articular distal radius fractures to nonoperative treatment in patients with these fracture type. Therefore, with this randomized controlled trial the investigators wish to determine the difference in functional outcome, assessed with the Patient Related Wrist Evaluation (PRWE), after open reduction and plate fixation compared to nonoperative treatment with closed reduction and cast immobilization.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Closed reduction and plasterimmobilisation | Active Comparator | The control group will be treated with closed reduction and cast immobilization. This will take place under local anaesthesia by means of a haematoma block with 20 cc Lidocaine 1%. Closed reduction will be preferably performed according to the Robert-Jones method. This involves increasing the deformity first, then applying continuous traction and immobilizing wrist and hand in the reduced position. Additional radiographs will be performed to verify the success of the reduction. After this has been confirmed, the wrist will be immobilized initially in a split plaster and later changed into a circular cast for five to six weeks immobilization in total. |
|
| Open reduction and internal plate fixation | Other | The surgery will be performed by a certified trauma surgeon. According to the current standard treatment protocol, antibiotic prophylaxis 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 muscle and the radial artery. After the fracture site is exposed, the fracture will be reduced and provisionally fixed under fluoroscopy with K-Wires/reduction forceps. An appropriate volar locking plate which best suits the anatomy of the wrist and the fracture type will be selected. Fracture reduction and screw placement will be confirmed by radiographic images. Additionally, fixation can be supported by a dorsal plate or radial column plate. This will be at discretion of the surgeon and depends on the fracture configuration and the position of the fragments. Wound closure will be performed at the discretion of the surgeon using standard techniques. |

| Quality of life measured with the SF-36 | Quality of Life assessed using the Short Form-36 (SF-36) questionnaire. The SF-36 is a validated multipurpose, short form health survey which contains 36 questions representing eight different health domains. These domains are combined into a mental and physical component scale. From each domain, scores ranging from 0 to 100 points are derived, with lower scores indicating poorer quality of life. | 6 weeks and 3, 6 and 12 months |
| Pain measured with the Visual Analogue Scale (VAS) | Pain as indicated on a visual Analogue Scale (VAS), in which 0 implies no pain and 10 the worst possible pain. Patients will be asked to give an estimation of the type and quantity of pain medication taken during all follow-up visits. | 1, 3 and 6 weeks and 3, 6 and 12 months |
| Range of motion measured with a goniometer | Range of motion of the wrist measured on both sides with a handheld goniometer in degrees. ROM includes pronation and supination, ulnar and radial deviation and palmar and dorsal flexion of the wrist. | 6 weeks and 3, 6 and 12 months |
| Grip strength measured with a dynamometer | Grip strength as measured with a dynamometer in kg as the mean of three measurements. Grip strength will be measured as a percentage of the uninjured side. | 6 weeks and 3, 6 and 12 months |
| Number of patients with loss of reduction | Radiographs will be performed to ensure that loss of reduction has not occurred. Loss of reduction is defined as <15° radial inclination, >15° of dorsal angulation or >20° of volar angulation, >3 mm shortening of ulnar variance or >2 mm of articular step-off or gap. Radial inclination, volar/dorsal tilt, ulnar variance and radial length will be measured digitally in the Picture Archiving and Communication System (PACS) on standard posterior anterior (PA), lateral carporadial and lateral X-rays of the wrist. If loss of reduction occured, operative treatment will be considered, but will be at discretion of the treating surgeon. | 1, 3 and 6 weeks and 3, 6 and 12 months |
| Cost-effectiveness and cost-utility measured with an economic evaluation questionnaire | Cost-effectiveness and cost-utility measured with an economic evaluation questionnaire based on the EQ-6D and the Standard Form Health and Labour questionnaire. | 6 weeks and 3, 6 and 12 months |
| Number of complications in both treatment groups | Number of complications in both patients treated with plasterimmobilisation and ORIF. Complications include loss of reduction, cross-overs from conservative to operative treatment, fracture malunion or non-union, wound and/or plate infection, tendon irritation and/or rupture, neuropathy and the occurrence of complex regional pain syndrome. | 1, 3 and 6 weeks and 3, 6 and 12 months |
