You develop this type of fracture in joints that you use too often. It is more common in athletes and people who start their workout without spending time in warm-ups. This closed fracture occurs when you break a bone due to a forceful contraction of a muscle. ![]() You usually get it in the bones of the spine usually due to a collapse of the anterior portion of the vertebra or advanced osteoporosis. You develop a compression fracture when at least two bones are forced against one another. It is an incomplete fracture when the two pieces of the bone partially avulse from each other–there will be some connection left between the both. You have a complete fracture if the bone is fragmented completely. The bone splits into two fragments–the fragments will jam into each other. This type of closed fracture occurs when there is too much pressure on two extremities of the bone. This type of fractureusually heals quickly. There will be torsion on the other side of the bone though. More common in children, it is partial fracture with one side of the bone unharmed. You have this type of fracture when the break is parallel to the long axis of the bone. This is a highly complicated injury and usually heals quite slowly. The bone will be broken into several fragments. Comminuted FractureĪmong all different types of fractures, comminuted fracture is a serious one. You get this type of fracture because of severe twisting force applied to the bone. You have a spiral fracture when the fracture line twists around the bone. You get a transverse fracture when something applies serious force at a right angle to the bone. This fracture is perpendicular to the axis of the bone. They are basically slanted fractures caused by an intense force applied at an oblique angle. In this type of fracture, the fissure runs diagonal to the axis of your bone. So it is more likely to develop an infection in this type of a fracture. There will be luxation of the bone and it will pierce through the epidermis. It is opposite to simple fracture and is also known as an open fracture. Simple FractureĪlso called closed fractures, they occur when your bone suffers breakage but does not pierce through the epidermis. They are then divided into many other categories. No matter what causes a fracture, it usually falls into one of two categories: simple and compound fractures. It can be a pathological fracture caused by a disorder such as osteoporosis, or it can be a traumatic fracture caused by extensive external forces. Fractures are quite common and an average person has at least two fractures during a lifetime. You get a fracture when your bone breaks due to extensive force that stretches the osseous tissue in the bone beyond limit. It can be a sprain, strain, dislocation, or even a fracture. For treating fractures in clinic, the selection of fixators should carefully take fracture types into account.No matter how careful you are, you will sometimes find yourself in situations where you end up sustaining an injury. Conclusions Fracture healing is affected by both fixator stiffness and fracture types. ![]() For type B and C fractures, when fixator stiffness was above 1.5 kN/mm, the change in fixator stiffness had no significant effects on recovery of biomechanical performance. For type A fracture, when fixator stiffness was 1.5 kN/mm, optimal biomechanical recovery of the fractured site could be obtained, while the change in fixator stiffness had a large impact on healing effect. The sensitivity of healing effects to change of fixator stiffness was also different. However, the appropriate fixator stiffness corresponding to each fracture type was different. Results Moderate fixator stiffness (1.5-2.5 kN/mm) shortened the healing time while ensuring recovery of biomechanical performance of the fractured bone. Methods Taking intramedullary nail fixation of long bone fracture as research objective, based on strain-regulated tissue differentiation theory, and combined with fuzzy logic algorithm and finite element analysis, the process of fracture healing was numerically simulated. Objective To systematically explore the change of fixator stiffness (0.05-7.50 kN/mm) on healing effects of seven different types of fractures (A1 simple spiral, A2 simple oblique, A3 simple transverse B2 wedge spiral, B3 wedge fragmented C2 complex segment, C3 complex irregular) under the OTA/AO fracture classification.
