Vitamin D Deficiency and its Implications
Courtesy: Prof Nabil Ebraheim, University of Toledo, Ohio, USA VITAMIN D DEFICIENCY Vitamin D is important for the proper maturation and development of bone and it also boosts our immunity. We use the term “deficiency” if the vitamin D level is below 20 ng/ ml. We use the term “insufficiency” if the vitamin D level […]
Trabecular Pattern of the Proximal Femur
Courtesy: Prof Nabil Ebraheim, University of Toledo, Ohio, USA TRABECULAR PATTERN OF THE PROXIMAL FEMUR There are important trabecular patterns in the proximal femur. It occurs according to Wolff’s Law in response of the bone to stress. There is a primary tensile trabeculae and a primary compression trabeculae. There also are secondary tensile and […]

Basic Principles of Fracture Healing
Courtesy: Dr Samir Qureshi, The Young Orthopod Channel FRACTURE HEALING Fracture Healing is a specialised type of wound healing consisting of a sequence of inflammation, repair and remodelling that helps to restore an injured bone. The way a fracture heals depend on the amount of movement occurring between the fracture fragments. When some amount of […]
Osseous tissue Cell anatomy and Matrix physiology
Courtesy: Prof Knoppy Bone has Cellular and Noncellular composition Four types of cells are found in bones: Osteoprogenitor cells, Osteoblasts, Osteocytes and Osteoclasts Osteoblasts are involved in bone deposition The Osteoclasts are large multinucleate Giant cells with a ruffled border, and are involved in bone absorption. Bone has orgnanic and inorganic component. Organic component consists […]
Physeal Zones and Abnormalities
Courtesy: Prof Nabil Ebraheim, University of Toledo, Ohio, USA This video describes the different physeal zones & their abnormalities. Growth plate has 3 zones- Reserve zone, proliferative zone & hypertrophic zone. Hypertrophic zone is again divided into zone of maturation , zone of degeneration & zone of provisional calcification. Reserve zone is the area where […]
Types of Collagen and its implications
Courtesy: Prof Nabil Ebraheim, University of Toledo, Ohio, USA This video describes about various types of collagen. Collagen is made by fibroblasts & there are about 20 types of collagen which constitutes 20% of our body proteins Type 1 collagen accounts for 90% of our body collagen & is associated with primary bone healing. It […]
Osteoclast and its Functions
Courtesy; Prof Nabil Ebraheim, University of Toledo, Ohio, USA The bone has two important cells – osteoclast and osteoblasts. Osteoclasts are irregular shaped giant cells that break down or reabsorbs bone. Osteoblasts are cells that are responsible for new bone formation. Osteoclast arise from either macrophages or monocytes . Monocytes fuse together to form […]
