Balancing AO Principles in Calcaneus Fractures
The calcaneus, also known as the heel bone, is responsible for transmitting the majority of the body's weight from the talus bone to the ground. Nearly every aspect of the management of complex calcaneus fractures is controversial. The anatomy of the calcaneus is complicated and treatment of fractures in this bone requires a comprehensive understanding of its anatomy, common fracture patterns, and displacement. An accurate reduction is essential to good patient outcomes. Treatment options include closed management, an extensile lateral open approach and the mini-open technique. This presentation highlights the indications for each technique, compares and contrasts their strengths and weaknesses, and provides case examples with discussion from some of the leaders in the field of calcaneus fracture management.

Fracture Healing - Everything You Need To Know - Dr. Nabil Ebraheim
Dr. Ebraheim's animated educational video describing fracture healing. The stability of the fracture decides what type of healing will occur. If there is a small amount of strain (below 2%), the primary bone healing will occur. The primary bone healing will occur like when you are using a compression plate. If the strain is between 2-10%, then secondary bone healing will occur such as when using a cast, rod or external fixator. In primary bone healing, you will need absolute stability, called Haversian remodeling cutting cone remodeling, or sometimes called intramembranous healing. Secondary bone healing will occur when the fixation is not rigid, such as with a cast, and there will be endochondral ossification. With an IM rod, there will be secondary bone healing, early on, there will be periosteal callus. Later on, there will be a medullary callus. The external fixator is predominantly periosteal callus with endochondral ossification, because most of the time the external fixator is not very rigid. When endochondral ossification fails, because the fixation is inadequate, you get hypertrophic nonunion and you will have predominantly type II collagen. The endochondral ossification at this point has failed and stability is needed in order to change the cartilage to bone. What are the stages of fracture healing? 1-Hematoma 2-Inflammation 3-Soft callus 4-Hard callus 5-Remodeling When the fracture occurs, there will be bleeding at the fracture site. It will make a fibrin blood clot. 1-Stage of inflammation Cells •Macrophages •Mesenchymal cells •Stem cells migrate to the fracture and form the granulation tissue and will release the growth factors. Granulation tissue tolerates the greatest strain before failure. COX-2 inhibitor and nonsteroidal depresses Runx2. Important for the differentiation of osteoblasts. 2-Stage of soft callus •Will occur within two weeks. •The amount of callus correlates with the immobilization. •The stiffer the immobilization, the less amount of callus. •Flexible fixation will result in endochondral ossification (abundant callus). •Secondary bone healing: healing through cartilage formation. The stability helps direct bone formation. Lack of stability helps the formation of cartilage, which later on can change to endochondral ossification. 3-Stage of hard callus •The collagen changes from predominantly type II, to be followed by type I. •Type I= bone •Type II =cartilage 4-Stage of remodeling •The stage of remodeling will begin at 2 weeks and continue many years after the fracture has healed. •The woven bone will be replaced by stronger, laminar bone and the fracture healing will be complete with the continuation of the medullary cavity. •The remodeling of the bone is influenced by the Wolff’s law (means that the bone is affected by stress). You need to be aware of this order of bone healing because sometimes it comes on the exam. Blood flow at the fracture site is very important for fracture healing. The blood will supply the fracture with nutrients and cells. Initially there Is decreased blood flow at the fracture site which will increase later on and the blood flow will peak at two weeks and return to normal after about three months. Distraction osteogenesis Can get type I and type II cartilage (predominantly type I) because there is more intramembranous ossification. How does the endochondral bone formation occur? •Chondrocyte proliferation then hypertrophy •Matrix mineralization •The chondrocytes die •Vascular invasion, ossification, and remodeling to lamellar bone. What are the growth factors involved in fracture healing? Bone morphogenic protein: osteoinductive causing the undifferentiated mesenchymal cells to differentiate into osteoblasts. Transforming growth factor beta (TGF-B1): will make the mesenchymal cells produce type II collagen and proteoglycans (trying to produce endochondral ossification) Insulin-like growth factor 2 (IGF-2): will stimulate type I collagen Platelet derived growth factor (PDGF): will be released from the platelets. Attracts inflammatory cells to the fracture site (chemotactic).
