Different studies have shown inter-observer reliability of approximately 60% (ranging from 42% to 92%), [7] [8] representing poor-to-moderate agreement of scale grading between health-care professionals. This is due to much of the criteria being at risk of observer errors, and is a known liability of this scaling system.
The original study reported that the test was 100% sensitive and reduced the number of ankle X-rays by 36%. [4] A second trial with a larger number of patients replicated these findings. [5] Subsequently, a multi-centre study explored the feasibility of implementing the rules on a wider scale. [6]
The ankle joint consists of the talus resting within the mortise created by the tibia and fibula as previously described. Since the talus is wider anteriorly (in the front) than posteriorly (at the back), as the front of the foot is raised (dorsiflexed) reducing the angle between the foot and lower leg to less than 90°, then the mortise is confronted with an increasingly wider talus.
Ankle osteoarthritis. For the ankle, the Kellgren–Lawrence scale, as described for the hip, has been recommended. [16] The distances between the bones in the ankle are normally as follows: [17] Talus - medial malleolus: 1.70 ± 0.13 mm; Talus - tibial plafond: 2.04 ± 0.29 mm; Talus - lateral malleolus: 2.13 ± 0.20 mm
Imaging for evaluation of ankle fractures can include x-rays, CT scans, and MRIs. Typically evaluation begins with x-rays, which can provide information about the mechanism of injury, severity of injury, and stability of fracture. The Ottawa ankle rules determine the necessity of obtaining x-rays in patients with acute ankle injuries. These ...
The Thomas test is a physical examination test, named after the Welsh orthopaedic surgeon, Hugh Owen Thomas (1834–1891), to rule out hip flexion contracture (fixed partial flexion of the hip) and psoas syndrome (injury to the psoas muscle). Illustration of the Thomas test.
The tibia is pulled forward to assess the amount of anterior motion of the tibia in comparison to the femur. An intact ACL should prevent forward translational movement ("firm endpoint") while an ACL-deficient knee will demonstrate increased forward translation without a decisive endpoint - a soft or mushy endpoint indicative of a positive test.
The Abbreviated Injury Scale (AIS) is an anatomical-based coding system created by the Association for the Advancement of Automotive Medicine to classify and describe the severity of injuries. [ 1 ] [ 2 ] [ 3 ] It represents the threat to life associated with the injury rather than the comprehensive assessment of the severity of the injury. [ 4 ]
