Tibia and Fibula (Lower Leg Bones): The tibia is the larger and stronger of the two bones in the lower leg, while the fibula is thinner and runs alongside the tibia. These bones articulate with the femur at the knee joint and with the bones of the foot at the ankle joint.

fibula Long bone partly fused to the tibia and forming the outer limb between the femur and the tarsus.

extremities of tibia and fibula in African giant pouched rat. The fibula extended below to form lateral malleolus bearing a facet for the articulation with fibular tarsal.

40 paired femura, tibiae and humeri of male Wistar rats (10–38 weeks, weight between 240 and 720 g) were analysed by DXA, pQCT scan and three-point-bending. Bearing and loading bars of the biomechanical setup were adapted percentually to the bone’s length.

The critical size defect was introduced into the rat fibula. Adult homozygous Athymic RNU Nude rats weighing (200–300 g) were administered buprenorphine at 0.5 mg/kg by subcutaneous injection into the right thigh 1 h prior to surgery.

Sep 1, 1999 · In the present study, the relevance of a recently developed segmental defect model in rat fibula to human fracture healing was investigated by evaluating temporal progression of rigidity of the fibula, mineral content of the repair site, and histological changes.

To investigate the effect of the fibula on growth of the tibia in the rat, (1) a sleeve of periosteum was removed from the middle third of the tibia, (2) a length of the fibula was excised, or (3) a sleeve of periosteum was removed from the middle ...

Sep 21, 2024 · The skeleton of a rat is a complex assembly of bones, cartilages, and joints that provides support, protection, and mobility. It consists of an axial skeleton (skull, vertebral column, rib cage) and an appendicular skeleton (pectoral and pelvic girdles, forelimbs, hindlimbs).

Dec 12, 2015 · Conclusion: The biomaterials used demonstrated biocompatibility and osteoconductive capacity that was capable of stimulating osteogenesis, even in bones with secondary mechanical and morphological functions such as the fibula of rats. Keywords: Durapatite, Fibula, Collagen, Osteogenesis.

We use a rat fibula defect, which surprisingly does not heal even when a simple fracture is introduced. In this model, the bone quickly resorbs most likely due to the non-weight bearing nature of this bone in rodents.
