Morphological and Morphometrical Study of Dry Fibula at Medical college of Western Nepal

Fibula, Morphology, Morphometry, Nutrient foramen, LocationAbstract
Introduction: The fibula bone lies lateral to the tibia. Despite the lack of a weight bearing, the fibula plays a pivotal role in the stabilization of the talocrural joint. The morphology and morphometry of fibula is important in the design and preparation of fibula flap transfer in mandibular reconstruction. The location of nutrient foramina is important for the vascularization of the fibular shaft. Hence, the present study aims to investigate the morphology and morphometry of fibula bone in Nepalese population.
Methods: This study was done on 50 dry fibulas in the Anatomy Department, Manipal College of Medical Sciences, Nepal. The maximum length of fibula, length and breadth of superior and inferior articulating facet were measured with the help of measuring scale, thread and vernier caliper for right and left fibula. The location of nutrient foramina on fibula of both sides was noted. Data collection was reported as mean ± SD and analyzed with MS Excel 2007 software.
Results: The mean length of right fibula was 33.21±1.42 cm and left fibula was 33.06±1.52 cm. The mean length and breadth of superior and inferior articulating facet was found to be between 1.25 cm to 1.75 cm for the right and left fibula. 77% cases of nutrient foramen were located in middle 1/3rd, 12.5% were located in upper 1/3rd and 10.41%were located in lower 1/3rd of the fibula. The majority of the nutrient foramina were located on the posterior surface of fibula.
Conclusion: The morphology and morphometry of fibula is of clinical importance because it will be helpful to surgeons during any surgical procedures such as bone grafting, bone repair and microvascular bone surgery in Nepalese population.
