31) (299). correlated age versus fracture type (Fig. Antara tibia dan fibula, tibia sepadan, pada bahagian atas, ke radium. Mechanism is usually due to vertical loading (e.g., in jumpers). The medial condyles superior surface is oval in form and extends laterally onto the side of medial intercondylar tubercle. of injury where there is less distortion of the normal anatomy. Fractures of the distal tibia, distal fibula, and talus are described together because of their frequent simultaneous injury. Editors. Each age group, sex and ethnicity was represented by 10 radiographs for a total of 270 females (ages 9–17) and 300 males (ages 11–20). Stage 1: No fusion: Absence of bony bridging between the diaphysis and the epiphysis, Stage 2: Unclear: Relationship of the epiphysis and the diaphysis is not discernable from stage 1 and early stage 3, Stage 3: Partial fusion: Partial to nearly complete fusion of the diaphyseo-epiphyseal junction, Stage 4: Complete fusion: Epiphysis is completely fused to the diaphysis. The possibility of graft resorption as well as immunologic response after this technique has not been investigated, but these concerns have plagued allograft usage in other transplant settings (Aponte-Tinao et al, 2016; Chapovsky & Kelly, 2005; Lozano-Calderon et al, 2016; Stevenson et al, 1991). It is on the medial side of the lower leg, next to the fibula. Of these injuries, 20% to 25% are open, and 75% are associated with fibula fractures. The distal tibia is exposed anteriorly without stripping of the periosteum; consequently, K-wires are placed according to the preoperative planning (Fig. Types of fracture–separation at the distal tibia and their relation to age. Longitudinal scan of the anterior aspect of the ankle shows the course of the anterior tibial tendon. The plate can be used as an alignment guide for reconstructing complex fractures and offers a variety of screw positions. Wiley-Blackwell. The MR imaging studies are beginning to demonstrate early transphyseal vessel communication between epiphysis and metaphysis (159, 286, 292) (Figs. Fracture lines describing these fragments have revealed ten types of pilon fracture which belong to two families, sagittal and coronal. The bulbous posterior process bears the attachment of the Achilles tendon. The tibia is the medial and larger bone of the leg. After fracture, there is a substantial risk of nonunion. (103); Spiegel et al. The forward flat part of the tibia is called the fibia, often confused with the fibula.. The cross-sectional anatomy of the distal tibia demonstrating the relevant neurovascular structures and their relationship to the surgical approaches. The tibia is ossified from three centers; a primary center for the diaphysis (shaft) and a secondary center for each epiphysis (extremity). The frequency, variable patterns, and growth arrest problems of distal tibial fracture–separations were well-illustrated in detailed presentations by Giuliani (123) and Bartl (18). Lateral to (on the outer side of) the tibia is the fibula, a smaller long bone that provides stability and assists with rotation of the ankle. 5 The Distal Tibia Locking Plate System â¢ A low-profile designed to help minimize potential discomfort and soft tissue irritationâ¢ Contoured plates mimic the anatomy of the distal tibiaâ¢ Anterolateral plate is available in wide and narrow widths to suit patient size title = "Anatomy of pilon fractures of the distal tibia", abstract = "In a series of 126 consecutive pilon fractures, we have described anatomically explicable fragments. The tibial articular surface, known as the plafond, forms a sagittal concavity covered with articular cartilage. After fixation, the ankle may be immobilized in a neutral position a short leg cast, posterior plaster splint, removable splint, or fracture boot. The anterior surface of the lower extremity is smooth and rounded above, and covered by the tendons of the Extensor muscles; its lower margin presents a rough transverse depression for the attachment of the articular capsule of the ankle-joint. The superior surface of the calcaneal body has an articular facet that forms the PSTJ with the talus. Posteriorly, the condyles are separated from each other by a shallow depression, the posterior intercondyloid fossa, which gives attachment to part of the posterior cruciate ligament of the knee-joint. Although not functionally a part of the knee, the fibula articulates proximally with the lateral aspect of the tibia, forming the proximal tibiofibular joint. The tibia is located in the front portion of the lower leg or what is more commonly known as the shin. Thus A pyramidal bone on the lateral side of the foot. Like other long bones, there are three parts of the tibia: proximal, shaft, and distal. Distal to the ankle is the foot. (OBQ04.114) A 56-year-old male sustains a Type IIIB open, comminuted tibial shaft fracture distal to a well-fixed total knee arthroplasty that is definitively treated with a free flap and external fixation. Anterior view, Bones of the right leg. Age ranges of epiphyseal fusion in the distal tibia and fibula of contemporary males and females. In some posttraumatic cases with extensive scarring on the posteromedial aspect of the ankle, it may be necessary to expose the tendon through a mini-incision in order to protect it. Conventional angiography or CTA should also be performed if associated vascular injury is suspected. The tibia is the main bone of the leg it has a proximal and distal end and a shaft articulating at the knee in proximal and ankle joints in the distal endit is the second largest bone in the body. Usually associated with fractures of distal fibula and/or disruption of distal tibiofibular syndesmosis. Nine months after fixator removal, he presents with a painful oligotrophic nonunion. (H) MR imaging defines the medial bone bridge (arrow) with marrow signal continuity across the physis between epiphyseal and metaphyseal bone. Common mechanisms include vertical loading from falls from height, motor vehicle collision, and sporting mechanisms such as skiing. The first metatarsal is much broader and stouter than the second to fifth metatarsals. Richard Buckley, Andrew Sands. of a well preserved HL identified in a human distal tibia are reported in this rapid communication. Deep dissection. Approximately 10–12% of distal tibial growth plate injuries have growth complications. It is sinuous and prominent in the upper two-thirds of its extent, but smooth and rounded below; it gives attachment to the deep fascia of the leg. The posterolateral approach to the distal tibia allows direct reduction of posterior malleolus fractures. CT scan is valuable in delineating these complex injuries and planning surgical repair. While the epiphyses are the two rounded extremities of the bone; an upper (also known as superior or proximal) closest to the thigh and a lower (also known as inferior or distal) closest to the foot. Deep dissection, Ankle joint. * Quenneville C, et al. Copyright © 2020 Elsevier B.V. or its licensors or contributors. In human anatomy, the tibia is the second largest bone next to the femur. The lateral condyle presents posteriorly a flat articular facet, nearly circular in form, directed downward, backward, and lateralward, for articulation with the head of the fibula. The distal articulation of the tibia and fibula means the place where the tibia and fibula form a joint at the end of the bones farthest from the origin of the limb. Dotter and McHolick reported an 18% incidence of negative growth sequelae (89). (B) A tomogram of the distal tibial epiphysis shown in A shows the clear-cut separation of the epiphyseal fragment from the adjacent epiphysis. 40-1). The talus possesses a sagittally convex superior articular surface known as the dome, which articulates with the tibial plafond to form the ankle joint. Most type I lesions result in good to excellent healing, and most type V lesions lead to fair to poor results. At this point, the subcutaneous tissue is thinnest, a result of the transverse arch of the midfoot with the apex roughly coinciding with the site of this artery. Detailed reports of type II, III, and IV lesions show a scattering of results with a fairly uniform distribution between excellent, good, fair, and poor in each type (283, 286). As in other vertebrates the tibia is one of two bones in the lower leg, the other being the fibula, and is a component of the knee and ankle joints. Malleolar ankle fractures result from rotational mechanisms, whereas distal tibial fractures (i.e., pilon fractures) are the result of high vertical loading forces, such as falls from heights and motor vehicle accidents.32 Often, long-axis compression throughout the proximal lower extremity can cause associated tibial plateau fracture, hip dislocation, or acetabular fracture.
