Is this trial a fit for you?

Likely a good fit

Ideal candidates are consenting adults 18–55 with trauma-related femur or tibia shaft fractures who are not taking bone-strengthening medications and have no severe organ disease or almond allergy.

Probably not a fit

Patients who require prescription bone-strengthening drugs for osteoporosis or urgent indications, those with severe cardiovascular/hepatic/renal disease, or those with almond allergy are unlikely to benefit from this intervention.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults (18–55) with trauma-associated femur or tibia shaft fractures presenting to Aga Khan University Hospital will receive Prunus dulcis (sweet almonds) as an intervention and be followed during their healing period. Fracture repair will be monitored using radiographic measures such as callus formation, callus bridging, and callus index, together with clinical assessments and safety monitoring. Patients already on bone-strengthening drugs, with severe cardiovascular/hepatic/renal disease, or with known almond allergy are excluded. The trial seeks to determine whether almonds offer a feasible, low-cost adjunct to support bone healing with acceptable safety.

Why it matters

Potential benefit: If successful, almonds could offer an affordable, widely available supplement to support bone healing with fewer side effects than some prescription bone-strengthening drugs.

How similar studies have gone: Animal studies and some small human studies suggest almonds or almond extracts can improve bone health and accelerate fracture healing, but robust clinical evidence in people with shaft fractures is limited.
