|- Brief summary||Rationale: |
The ideal treatment for extra-articular distal radius fractures remains a controversial issue. Excellent results have been described both in patients treated with a plaster and in patients treated with open reposition and internal fixation (ORIF) with a volar locking plate. Recently, the use of Volar Locking Plates has become more popular, due to its better performance in osteoporotic bone. Moreover, anatomic reduction and stable fixation of these fractures allows for early mobilization and may theoretically lead to a better function.
To compare the functional outcome of ORIF with a volar locking plate to closed reduction and plaster immobilisation in patients with extra-articular distal radius fractures.
Multi Center Randomized Controlled Trial.
All consecutive adult patients with an AO type A distal radius fracture which was successfully reduced within 12 hrs of presentation at Emergency department of the participating hospitals.
This study will randomise between open reduction and internal fixation with a volar locking plate and plaster immobilisation.
Main study parameters/endpoints:
Primary outcome: Disability of the Arm, Shoulder and Hand (DASH) score. Seconday outcome: Patient-Rated Wrist Evaluation score (PRWE). Quality of life (QoL SF-36), pain as indicated on a Visual Analogue Scale (VAS), Range of Motion (ROM), radiological outcome and complications.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness:
Patients will be asked to return to the hospital for follow up at; one, three and six weeks and three, six and twelve months. During these visits patients will be asked about any complaints and/or complications and physical examination will be performed. The risks associated with the treatment under study comprise standard risk for undergoing a surgical procedure related to anaesthesia, post-operative pain and wound infection.
