The AP view is projected through the body of the talus and distal tibia. For bony pathology, there are 3 standard views for a radiograph. The standard radiographic measures presented in the present study provide the foundation for understanding the osseous foot and ankle position in a normal population.Īnkle foot normal ankle angles normal foot angles radiographic angles.Ĭopyright © 2016 American College of Foot and Ankle Surgeons. Imaging of the foot and ankle can be beneficial to rule in or rule out pathology after trauma to the foot or ankle or when an injury is not progressing with conservative management. The radiographic angles and measurements presented in the present study demonstrate a comprehensive and useful set of standard angles, measures, and reference points that can be used in clinical and perioperative evaluation of the foot and ankle. All angles were measured by both senior authors twice, independent of each other. While pressing on the bone, work your way down to the ankle joint, pushing on the front and then the back of the bone. By moving slightly forward and backward you should be able to identify where the bone is and where the muscle is. Start several inches above the ankle and press firmly on the bone. Anteroposterior and oblique views are most common views that are ordered on the. A total of 4 measurements were made from the axial view, 12 from the lateral view, and 17 from the anteroposterior view. It is usually a little wider than your thumb. Xray of the foot is ordered in various ailments of the foot including trauma. The radiographic measurements were performed on standard weightbearing anteroposterior, lateral, and axial views of the right foot. Unremarkable radiographic examination of the right/left ankle. There is no soft tissue swelling or joint effusion. No fracture or dislocation is identified. Inability to weight bear, both immediately and in the casualty department. Bone tenderness at the posterior edge/tip of medial malleolus (6cm). A total of 33 angles and reference points were measured on 24 healthy feet. Technique: view/s of the right/left ankle. Ankle arthritis commonly results from a history of trauma to the ankle either a severe ankle injury, such as a bad ankle. an ankle radiograph is required only if there is pain in the 'malleolar zone' and any of these findings: Bone tenderness at the posterior edge/tip of lateral malleolus (6cm). If a fibular fracture is not seen on the ankle radiographs, radiographs of the. Critical preoperative planning and intraoperative and postoperative evaluation of radiographs are essential for proper deformity planning and correction of all foot and ankle cases. Ankle radiographs were obtained (Figure 1). Objective radiographic measures are the building blocks for surgical planning. The anterior and posterior extra-capsular region of a normal ankle joint should appear as a fat-like density. Computed tomography provides good visualization of subtle bone injuries and may detect clinically imported soft-tissue injuries.The limb deformity-based principles originate from a standard set of lower extremity radiographic angles and reference points. An ankle effusion suggests a significant injury to the ankle joint. Ankle effusion size was 11.2 mm in the group without fracture and 17.1 mm in the group with fracture (P or = 15 mm is a reasonable threshold to prompt additional imaging. Fracture sites included: posterior or lateral malleoli (n = 4), calcaneus (n = 1), or talus (n = 7). Twelve patients (46%) had radiographically occult fractures identified with CT. Ankle effusion size was measured from initial lateral ankle radiographs. Patients were excluded if ankle trauma was sustained more than 48 h previously or if a fracture was visible on initial photographs.Īll subjects (n = 26) underwent computed tomography (CT) of the ankle in sagittal and coronal planes. To assess the value of an ankle effusion on plain radiographs as a predictor of radiographically occult fracture after acute ankle trauma.Ĭonsecutive patients with acute ankle trauma and radiographic evidence of an ankle joint effusion.
