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).

Biological Fixation of Posterior Wall Fractures of Acetabulum
Present here is the audio-video of the live surgery where in posterior wall of the acetabulum has been stabilised biologically by innovating minimal invasive technique by Prof NK Magu et al. It is published now in journal of Orthopaedic trauma April 2011, and is being practiced in developing counties as is evident by its citations. The innovative technique has now been used as a part of combined anterior & posterior surgical approaches in the management of complex fractures of the acetabulum; published in Indian journal of Orthopaedics. The video is been uploaded to share Pelvi-Acetabular surgeons universally to help the growing surgeons in improving their skill. In the video uploaded the posterior wall is stabilized with two screws by creating a window between gluteus medius and Pyriformis muscles superiorly. A second window can be created between ischial tuberosity and short rotators. Thus a reconstruction plate is slid under the sleeve of rotators through the two windows to buttress the posterior wall. The technique is also applicable for the stabilization of transverse; transverse and posterior wall fractures, and posterior column. A short clip of video, how to slide a plate under the short rotators using superior and inferior windows is also being uploaded along with the principle video for better understanding of the surgeons. Click here to view this video - https://www.youtube.com/watch?v=saEww0ha6Vc&feature=youtu.be. I am sure, the technique will become popular amongst the growing and the experienced surgeons to complete the surgery in the shortest possible time, with minimal blood loss, biologically preserving the integrity of the soft tissues thus minimizing the complications. Regards, NK Magu Professor Orthopaedics

Locking Compression Plate (LCP)
The Locking Compression Plate (LCP) is a new development of the screw-plate system that allows the combination of standard plate technology and locking screws with angular stability. The special characteristics of the LCP are: - Angular stability in combination with interfragmentary compression. - In addition to conventional indications, the LCP is particularly well suited for the treatment of juxta-articular fractures and for osteoporotic bone, as well as for the use of percutaneous techniques.

Treatment of ankle fractures in LICs
This webinar “Treatment of ankle fractures in low-income countries”, held on October 24, 2016, was given by two AO Alliance (AOA) orthopedic trauma surgeons with extensive knowledge of and expertise in such injuries, Dr Omar Faruque Golam Kibria (Bangladesh) and Dr Leonard Banza (Malawi). Ankle fractures and fracture-dislocations present an enormous challenge to orthopedic clinicians and practitioners especially in countries with fewer resources. Fortunately, the vast majority of these injuries can be treated successfully with closed methods of splinting or plaster of Paris. However, mismanagement of these fractures could result in pain, stiffness or deformity, leading to severe functional disability. The webinar aims to help viewers: recognize that nonoperative treatment of ankle fractures requires close follow-up to identify loss of reduction; clearly communicate with patients and their family the treatment plan, expectations and possible referral; describe and apply appropriate nonoperative and operative treatment of ankle fractures; and understand the pitfalls of syndesmotic injuries and their potential to lead to poor outcomes.

Tibial Pilon Fracture  - Everything You Need To Know - Dr. Nabil Ebraheim
Dr. Ebraheim’s educational animated video describes tibial pilon fractures. High energy axial load injury. Soft tissue injury is bad. Closed or open fracture and ankle joint are usually involved. Metaphysis of the tibia is usually involved. No immediate open reduction and internal fixation because soft tissue is usually bad. Early ORIF is not recommended. Initially, the treatment is usually closed reduction and a splint followed by staged ORIF. In the operating room, start by applying external fixator. This decreases the incidence of wound complication and deep infection. When internal fixation is used, it is better to use minimally invasive fixation. Wait 1-3 weeks depending on the magnitude of the injury, the anticipated surgery and the presence of the wrinkle test. After application of the external fixator, get a CT scan to check the joint and the fragments. This will help you to select the best operative approach in the future after the soft tissue condition improves. The physician needs to be aware that the AP radiographs may look OK, however, it may be misleading. The joint usually has three fragments attached to ligaments. Because the ligaments are intact, the fragments can be pulled by the external fixator, which is called ligamentotaxis. The three fragments are: 1-Medial malleolus: attached to the deltoid ligament. 2-Anterolateral fragment: Chaput fragment (attached to the anterior inferior tibiofibular ligament). in children, this fragment is called Tillaux fracture. If the fracture involves avulsion of the fibula, it is called Wagstaffe fracture as rarely seen in some ankle fractures. 3-Volkmann fragment: posterolateral fragment attached to the posterior inferior tibiofibular ligament. In this CT scan, you can see the three fragments of the pilon fracture as well as the joint impaction. When the fibula is intact, the lateral collateral ligament of the ankle may rupture (fibula is intact in 20% of the cases). The break travel time in driving return to normal 6 weeks after initiation of weight bearing. In ankle fractures, it returns to normal 9 weeks after fixations (post-operatively). The goal of surgery is anatomic reduction and stabilization of the articular surface. May start with fixation of the fibula with a plate or with a screw ( in some cases the screw is better because it is minimally invasive). Fibular plate may add stability to the external fixator of the tibia, especially if there is a defect or comminution of the metaphysis of the tibia. Plating of the fibula adjunct to external fixation of the tibia. When there is a metaphyseal defect of the tibia, plating of the fibula can enhance the stiffness of the external fixator. Axial loading 2.2 times stiffer with plated fibula. Torsional force has no significant difference. Approaches are many and it varies between limited approach and extensile approach. Try to protect the superficial peroneal nerve. Dual incisions approach. Make sure that the distance between the incisions is no less than 7 cm. this is controversial. Everybody agrees that staged ORIF is the best. Significant disability in physical function was noted even with successful treatment in 36-item short form survey (SF-36). Improvement of function and pain may take up to 2 years and eventually, about 10-15% may need arthrodesis. Pilon fracture with a fracture of the tibial shaft: Do fixation of the articular surface (usually percutaneously) then do fixation of the tibial shaft, usually with IM rodding. Put external fixator calcaneal pins or talar pins. I usually put the calcaneal pin on the medial side of the ankle. Be aware of the location of the neurovascular structures, error in placement or the direction of the calcaneal pin can interfere with the neurovascular bundle. Avoid the bulge area. Application od the calcaneal traction pin is done at the posteromedial site. There is a ¾ distance between the palpable tip of the medial malleolus and the heel. The calcaneal transfixation pin is inserted in a transverse direction. It is better to keep the pin away from the area of future incisions. Talus pin insertion •Pin insertion should be medial to lateral. •Anterodistal to anterior colliculus. •Placement should be in 10 degrees anterocephalad direction. Three principles of pilon fracture: 1-Anatomical reduction 2-Stable internal fixation 3-Early range of motion. Achieving these three principles in every case of pilon fracture may not be possible.   Become a friend on facebook: http://www.facebook.com/drebraheim Follow me on twitter: https://twitter.com/#!/DrEbraheim_UTMC

Treatment of open tibia fractures in LICs
The webinar “Treatment of open tibia fractures in low-income countries”, held on October 26, 2015, was presented by Dr Subhas B Shah (Nepal) and moderated by Dr Nicholas Lubega (Malawi), two AO Alliance (AOA) trauma surgeons with extensive knowledge of and expertise in the realities of trauma care in low-income countries (LICs). Open tibia fractures have increased in LICs along with a growth in disposable incomes and the number of vehicles on the road. Little has been done for road safety and prevention of injuries. On the treatment side, limited resources, scarcity of hardware and clean operative environments continue to challenge surgeons and others providing surgical care. This first-ever webinar sponsored by the AOA addresses these timely issues, and shows that adequate and resource-specific methods of managing open tibia fractures in LICs follow the same general principles as those in the developed world: prevention of infection; obtaining bone union; and returning to pre-injury function.
