Although talar fractures account for less than 1% of all fractures, they commonly result from high-energy trauma and may lead to complications and long-term morbidity if not recognized and managed appropriately. fractures) [11], likely owing to disruption of all three major blood supply vessels to the injured talus. They are classically referred to as "snowboarder fractures" because the injury often results from forced dorsiflexion and inversion, which reflects the orientation of the foot while strapped into snowboard bindings. To more easily understand the fracture pattern, and particularly if surgery is being planned, a CT scan will be ordered.

Outcomes: The patient had excellent functional and radiological outcomes following surgical management. 2022. J Bone Joint Surg Am 52:991 . (image 5). Shamrock A & Byerly D. Talar Neck Fractures. visualized on oblique view of the foot (image 3) and can be very subtle on AP RSNA members have free access to all RadioGraphics content. Diagnosis is made with radiographs of the foot but frequently require CT scan for full characterization. Computed tomographic scan images were also similar showing a distinct fracture line through the posterolateral aspect of the body of the talus extending into the subtalar joint. Correct approach selection in talar neck injuries is crucial to obtain adequate access to the entire fracture site avoiding malreduction and angular deformity. Given the uncommon nature of talar fractures most studies included few patients, and there is room for discussion as to the correct treatment and risks following the talar neck fracture. Musculoskeletal. PURPOSE: To describe the clinical setting and pattern of talar insufficiency stress fractures as diagnosed with magnetic resonance (MR) imaging. They represent one of the most common types of talus fracture (~30-50%), along with chip and avulsion fractures of the talus (~40-49%). 13, Journal of Clinical Medicine, Vol. Talar fractures are an uncommon injury, accounting for <5% of all foot fractures. 4, European Journal of Orthopaedic Surgery & Traumatology, IEEE Transactions on Radiation and Plasma Medical Sciences, Vol. 6. 1A-D Fractures of the neck of the talus based on the modied Significant marrow edema is seen in lateral aspects of talar dome. disruption of the subtalar joint, talonavicular joint or the ankle mortis The vast majority are either intra-articular or lead indirectly to an intra-articular incongruity through a dislocation at the talar neck. You can use Radiopaedia cases in a variety of ways to help you learn and teach. What is a talar neck? 9, Journal of Orthopaedic Surgery and Research, Vol. Talar fractures are divided by anatomic region: head, neck, and body. 42, No. The ankle joint is formed when your talus connects to your tibia and fibula (lower leg bones). Talar head fractures can be treated conservatively if nondisplaced, warranting careful radiographic and CT evaluation to assess rotation, displacement, and extension into the neck. This type of fracture often occurs during a high-energy event, such as a car collision or a fall from a significant height. Neck dissection For anterior neck strap . Mild marrow edema is seen in medial cuneiform bone. Associated soft-tissue injury can occur, especially with increasing severity. . PDF | Talar neck fractures occur on a continuum of injury severity. In a sacrum and coccyx x-ray report of even date, he provided impressions of Type III coccyx with anterior angulation, and no fracture or dislocation. Talar neck fracture is often best visualized on oblique view of the foot (image 3) and can be very subtle on AP view of the foot (image 4). Treatment is emergent reduction of the talus following by internal fixation in an acute or delayed fashion. It is necessary to remove any jewelry or clothes before performing the complete radiological examination.
