A Case Report on Third Head of Biceps Femoris Muscle | Chapter 14 | New Frontiers in Medicine and Medical Research Vol. 6

 Variants of the biceps femoris, such as an auxiliary head of the biceps femoris, can be encountered on occasion. During regular cadaveric dissection at the department of anatomy, All India Institute of Medical Sciences, Jodhpur, we discovered a case with an accessory head of biceps femoris in both lower limbs.

The biceps femoris' long head fibres form the muscle belly, which runs down medially to the medial superior portion of the tibia's medial condyle. On the right side, the insertion point resembles a sheath and integrates halfway with the thigh's medial intermuscular septum. On the left side, the insertion seems to be a thin sheath at first, then a thin muscle belly. The muscle belly is slender in compared to the long and short heads of the basic muscle bellies. The left side has a thickness of roughly 3.7mm on the higher end and thinner on the lower end, whereas the right side has a thickness of around 3.75mm. The right side of the muscle belly is around 5cm long, whereas the left side is about 5.5cm long. After then, the muscular belly creates a sheath with a length of approximately.5mm before returning to its original length of around 3.5cm. A short head appears high above on the left side, whereas the right side is normal.

Morphological Variations of Nutrient Foramina in Lower Limb Long | Chapter 5 | Recent Research Advances in Biology Vol. 9

 Background: The nutrient arteries, which enter through the nutrient foramen, provide the majority of blood supply to the long bones. A nutrient foramen is a hole in the bone shaft that allows blood vessels in the medullary cavity of the bone to pass through. The nutrition foramen of all bones is directed away from the growing end and has a specific position for each bone. The goal of this study was to look at the topographic architecture and morphology of the nutrition foramina in adult human lower limb long bones. Materials and Methods: A total of 150 lower limb long bones, 50 femora, 50 tibiae, and 50 fibulae, were used in the study. The bones were taken from the Punjab Institute of Medical Sciences' department of anatomy in Jalandhar. The number and position of nutrient foramen in distinct lower limb long bones were observed to vary. Double and triple foramina were found in the femur. Nutrient foramen were not found in the femur or fibula. Conclusion: Knowing the topography of these foramina is useful in avoiding injury to the nutrition vessels during specific surgical procedures in orthopaedics, as well as in plastic and reconstructive surgery.
