Introduction: Introduction: Nutrient foramina play a critical role in supplying blood to the clavicle, and their variations are of clinical significance in orthopaedic and reconstructive surgeries. However, limited data are available on their morphology and distribution in the Indian population.
Aim: To analyse the number, location, direction, and foraminal index of nutrient foramina in adult human clavicles.
Materials and Methods: A cross-sectional study was conducted on 100 dry adult human clavicles (50 right, 50 left) of unknown age and gender from the Department of Anatomy, SGT University, Gurugram, Haryana, India from May 2025 to September 2025. Each clavicle was examined for the presence, number, location and direction of nutrient foramina. Morphometric parameters, including clavicular length, distance of foramina from the sternal end, and foraminal index, were measured using a digital Vernier calliper.
Results: Nutrient foramina were present in 98% of clavicles 49/50 on each side single foramina predominated 31 (63.3% left, 69.4% right), followed by double 13 (26.5% both sides) and triple 5 (10.2% left, 4.1% right). Most foramina were located in the middle third 43 (84.3% left, 84.3% right), followed by the lateral third 6 (11.8% left, 7.8% right) and the medial third 2 (3.9% left, 7.8% right). The majority (99%) of foramina were directed towards the acromial end. The mean clavicle length was 135.27 mm, the mean distance of foramina from the sternal end was 72.96 mm, and the mean foraminal index was 53.95. Most foramina were located in the middle third and commonly situated on the posterior surface (67%), followed by the inferior surface (39%).
Conclusion: The clavicle typically contains a single nutrient foramen, situated in the middle third on the posterior surface and directed laterally.
