Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients presenting to the emergency departments or orthopaedic outpatient clinics of the trial sites with distal radius fractures will be assessed for inclusion in the study. Eligible patients invited to participate. Consenting patients will complete baseline assessments conducted by a hand therapist or orthopaedic surgeon prior to group allocation. Allocation will be performed by the orthopaedic surgeon booking the surgery after the baseline assessments have been completed using concealed, opaque envelopes containing a randomly generated allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients providing written informed consent for participation in this trial will be randomly assigned to either early intervention group (titianium or stainless steel volar multi-axial locking plates).The randomisation sequence will be computer generated and concealed in sequentially numbered sealed, opaque envelopes by a person, not otherwise associated with this research. Each envelope will contain a sheet of paper with the words either “TITANIUM” or “STAINLESS STEEL”.
Masking / blinding

Other design features
Rehabilitation will commence within 2 days of surgery and be performed by occupational therapists who have training in hand therapy. A standard post-operative therapy protocol will be followed.

Statistical methods / analysis
Study Design
Randomised Clinical Trial with two intervention groups.

Statistical Methods
Baseline demographic and clinical data will be reported using descriptive statistics and tabulated (e.g. Students t-test for continuous variables and Pearson chi-square for categorical variables). Between group differences in baseline data will be examined using unpaired conventional tests of hypothesis (such as unpaired t-tests) depending on the nature of the data. Between group and within group differences in outcome measures over time will be examined using a priori unpaired and paired conventional tests of hypothesis (such as Analysis of Variance with simple effects examined using t-tests) depending on the nature of the data. Bonferroni adjustments for multiple comparisons will be made where appropriate to mitigate risk of type-1 error. The complication rates will be reported in terms of frequency. The frequencies of complications will be compared using statistical analysis such as the Pearson chi-square statistic.

Summary
Brief summary
Distal radius fractures are among the most common fractures seen in the hospital emergency department. In recent years with the advent of low profile plating, open reduction and internal fixation (ORIF) using volar plates has become the surgical treatment of choice in many hospitals. However, it is currently unknown which plating systems have better clinical
and radiological outcomes following surgery, and also the lowest complication rates. Few studies have compared
different types of plates, which may have different plate and screw designs, features or may be manufactured from
different materials (for example, stainless steel or titanium). This study will specifically investigate and compare the
clinical and radiological outcomes and complication rates of two commonly used volar plating systems for fixation of
distal radius fractures: one made from stainless steel (Trimed Volar Plate) and the other made from titanium (Medartis Volar Plate).



This study will use a two group (intervention) blinded (blinded outcome assessor, blinded data analysis, concealed randomisation, blinded participant) randomised trial in an
adult population.

A suite of outcome measures recommended for this patient group will be used. These measures include an assessment of range of movement, strength, function (quickDASH and Patient Rated Wrist Evaluation), pain(VAS) , complications (medical chart and self-report), quality of life (EQ5D),
radiological outcome (XRay) and patient
satisfaction (VAS). These outcomes will be administered by a blinded assessor at seven time points: baseline, 2
weeks, 6 weeks, 3 months, 6 months, 1 year, and 2 years.
