Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
After surgical fixation and deemed medically stable, participants will be randomly allocated to an intervention group or placebo-control group. For the intervention group, participants will receive an initial oral 250,000IU (5 x 50,000IU) vitamin D3 tablets within 7 days following surgery. Both groups will receive oral maintenance vitamin D3 and calcium (800IU vitamin D3, 1000mg calcium daily) for 26 weeks and will follow the usual hip fracture rehabilitation pathway.

Treatment: Drugs
Comparator / control treatment
Participants in the placebo group will receive a one-off dose of 5 x microcelllulose pills initially followed by oral maintenance vitamin D and calcium (800IU vitamin D3, 1000mg calcium).
Control group
Placebo

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After completion of the baseline assessment, participants will be formally entered into the study and randomised to intervention or control groups. It will be performed centrally by an investigator not involved in recruitment or assessments. The allocation will be concealed by the study staff ringing a central telephone number to be notified to which group the participant has been randomised.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will occur using a computer-generated random number schedule with variable block sizes.
Masking / blinding
Blinded (masking used)
