Could a common diabetes drug help seniors heal faster after a broken hip?
NCT ID NCT07179042
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This pilot study tests whether metformin, a common diabetes drug, can help older adults recover muscle and function after a hip fracture. Sixty people aged 60 and older will take either metformin or a placebo daily for 4 months after surgery. The main goal is to see if the study is feasible and if metformin helps preserve thigh muscle size and improve mobility.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Metformin
- What this could lead to
- If it works, this could point toward a simple, low-cost way to improve recovery and prevent muscle loss after hip fracture in older adults.
- What could go wrong
- This is a very early pilot study with only 60 people, so results may not be conclusive. Metformin is generally safe but can cause stomach upset, and the study excludes people with kidney problems or diabetes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 60y and older. * Displaced hip fracture (femoral neck, intertrochanteric femur, subtrochanteric femur fracture). * Low energy mechanism of injury (ground level fall, etc). * Operative treatment within 72 hours of injury. * Previously ambulatory. Exclusion Criteria: * History of kidney disease or failure (CKD \> stage 4; eGFR \< 45 mL/min/1.73m2). * History of diabetes mellitus (HbA1c \> 6.5). * Associated lower extremity fracture (ipsilateral or contralateral). * Pathologic fracture. * Presence of infection at the fracture site. * History of metabolic bone disease (Pagets, etc.). * Severe cognitive impairment (Six Item Screener with 3 or more errors). * Stage 5 Parkinson's Disease. * Open fracture. * Risk of developing metformin-associated hypoglycemia (e.g., hepatic impairment (by history or screening laboratory assessment), presence of hypoglycemia at screening, history of adrenal or pituitary insufficiency, alcohol use disorder, subjects unable to maintain normal oral intake). * Severe hepatic impairment (Child-Pugh C). * Expected survival \< 6 months (based on clinical judgement).
