  • Pilon Fractures a Review and Update
    The Northern Ohio Foot and Ankle Journal Official Publication of the NOFA Foundation Pilon Fractures: A Review and Update by James Connors DPM1, Michael Coyer DPM1, Lauren Kishman DPM2, Frank Luckino III DPM3, and Mark Hardy DPM FACFAS4 The Northern Ohio Foot and Ankle Journal 1 (4): 1-6 Abstract: Pilon fractures are complex injuries due to many factors. The distal tibia lacks any muscle origin which makes it vulnerable to comminuted fractures. The soft tissue coverage is minimal at this level which leads to a higher propensity for open injuries. Conservative care is rarely indicated. Surgical planning must include advanced imaging to define the fracture pattern. Staging the injury to allow for optimization of the soft tissue envelop through the use of external fixation has many advantages compared to early open reduction internal fixation. The die punch fragment lacks any ligamentous attachments and possess a difficult task for anatomic reduction. The viability of the soft tissue, the amount of comminution, as well as the impaction force and rotation all must be considered for proper surgical planning.

  • Pilon Fractures of the Ankle­Orthoinfo ­ AAOS
    4/20/2016 Pilon Fractures of the Ankle­OrthoInfo ­ AAOS Pilon Fractures of the Ankle This article addresses pilon fractures—a specific type of fracture that occurs in the lower leg near the ankle. To find in­depth information on ankle fractures, please read Ankle Fractures (Broken Ankle) (topic.cfm? topic=A00391). A pilon fracture is a type of break that occurs at the bottom of the tibia (shinbone) and involves the weight­ bearing surface of the ankle joint. With this type of injury, the other bone in the lower leg, the fibula, is frequently broken as well. A pilon fracture typically occurs as the result of a high­energy event, such as a car collision or fall from height. Pilon is the French word for "pestle"—an instrument used for crushing or pounding. In many pilon fractures, the bone may be crushed or split into several pieces due to the high­energy impact that caused the injury. In most cases, surgery is needed to restore the damaged bone to its normal position. Because of the energy required to cause a pilon fracture, patients may have other injuries that require treatment as well. Anatomy The two bones of the lower leg are the: Tibia—shinbone Fibula—smaller bone in the lower leg The talus is a small foot bone that works as a hinge between the tibia and fibula. Together, these three bones—tibia, fibula, and talus—make up the ankle joint. Normal foot anatomy. Description Pilon fractures vary. The tibia may break in one place or shatter into multiple pieces.

    Pilon Fractures - OrthoInfo - AAOS 6/10/12 3:03 PM Copyright 2010 American Academy of Orthopaedic Surgeons Pilon Fractures Pilon fractures affect the bottom of the shinbone (tibia) at the ankle joint. In most cases, both bones in the lower leg, the tibia and fibula, are broken near the ankle. Pilon is a French word for pestle, an instrument used for crushing or pounding. In many pilon fractures, the bones of the ankle joint are crushed due to the high-energy impact causing the injury. Pilon fractures may be considered high-energy ankle fractures. Because of the energy required to cause this type of fracture, 25% to 50% of patients have additional injuries that require treatment. Cause Pilon fractures are most often caused by high-energy impacts, such as: Fall from height Motor vehicle/motorcycle collisions Skiing Risk Factors Age. The average age of someone with a pilon fracture is 35 to 40 years old. Pilon fractures are rare in children and elderly people. However, as our population ages, seniors will account for a larger amount of these fractures. Male. Men are three times more likely than women to have pilon fractures. A pilon fracture often affects Air Bags both bones of the lower leg. In recent years, there has been an increase in pilon fractures. This is due to the impact airbags have had in saving people's lives. Before there were airbags, most people did not survive high-speed car crashes. More people survive these crashes now, but because airbags do not protect the legs, there are also more leg injuries like pilon fractures.

  • Fracture Dislocations of the Proximal Interphalangeal Joint
    FRACTURE DISLOCATIONS OF THE PROXIMAL INTERPHALANGEAL JOINT BY RICHARD KANG, MD, AND PETER J. STERN, MD Fracture dislocations of the proximal interphalangeal joint may occur by several different mechanisms of injury and are of 3 basic fracture patterns: palmar lip fractures, dorsal lip fractures, and pilon fractures. Proper treatment of these injuries is predicated on maintenance of concentric reduction of the joint, restoration of joint stability, and institution of early motion. Anatomic reconstitution of the articular surface, though ideal, is less important. Many methods are available to treat these injuries. Understanding the fracture within the context of a stability-based classifi- cation system helps to guide in the selection of the most appropriate treatment.

The injury is caused by high energy axial load either from motor vehicle accidents or a fall from height. The treatment of these fractures has caused controversy among surgeons due to mixed outcomes. Here we report a case of pilon fracture in a 45 year old male patient who has sustained the injury as a result of a fall from a height of approximately 12 feet. We describe why it is absolutely crucial that the patient is treated with external fixation initially and evaluate its merits and drawbacks as well as ways to minimize the complications associated with external fixation of open intra-articular distal tibial fractures.
