Replenishment of Vitamin D in Hip fractured Patients (REVITAHIP) Trial

This trial — called REVITAHIP — is studying whether giving high-dose vitamin D supplements soon after a hip fracture can help older adults recover better. Hip fractures are serious injuries for older people and often lead to long-term disability. Vitamin D is important for bone health and muscle strength, and many older adults are deficient. Researchers want to see if quickly correcting low vitamin D levels helps people regain their mobility faster. You may be eligible if: - You are 65 years or older - You have recently broken your hip and had surgery to repair it - You are able to take a loading dose of vitamin D within 7 days after surgery - You (or your authorised representative) can provide informed consent You may NOT be eligible if: - You were unable to walk before your fracture - You are expected to live less than 1 month - You have high calcium levels in your blood - You have a history of kidney stones, thyroid overactivity (thyrotoxicosis), Paget's disease, or active cancer - You have significant kidney or liver problems - You are already taking a high dose of vitamin D (more than 1000 IU per day) Talk to your doctor about whether this trial might be right for you.
