What is a mortise view xray?
The AP mortise view is done with the leg internally rotated 15-20o so that the x-ray beam is perpendicular to the inter-malleolar line. This view permits examination of the articular space (clear space).
What is mortise in ankle joint?
The ankle joint is formed by three bones; the tibia and fibula of the leg, and the talus of the foot: The tibia and fibula are bound together by strong tibiofibular ligaments. Together, they form a bracket shaped socket, covered in hyaline cartilage. This socket is known as a mortise.
What is a mortise projection?
This projection is the most pertinent for assessing the articulation of the tibial plafond and two malleoli with the talar dome, otherwise known as the mortise joint of the ankle 1,2. osteoarthritis of the ankle.
In which view ankle is Dorsiflexed?
The ankle AP mortise (mortice is equally correct) view is part of a three view series of the distal tibia, distal fibula, talus and proximal 5th metatarsal.
How do you get a mortise view?
Patient position
- the patient may be supine or sitting upright with the leg straightened on the table.
- the leg must be rotated internally 15° to 20°, thus aligning the intermalleolar line parallel to the detector.
- internal rotation must be from the hip; isolated rotation of the ankle will result in a non-diagnostic image.
Is ankle a hinge joint?
The ankle joint is a hinged synovial joint with primarily up-and-down movement (plantarflexion and dorsiflexion). However, when the range of motion of the ankle and subtalar joints (talocalcaneal and talocalcaneonavicular) is taken together, the complex functions as a universal joint (see the image below).
How do you do a mortise view?
How do I take Broden’s view?
Heel Lateral Rotation (Broden Method) Position of patient Supine position. The radiologic technologists may adjust small sandbag under each knee of the patient. Position of part Ankle joint held in right-angle flexion. Rotate leg and foot 45 degrees laterally.
What do you need to know about the mortise view?
Ankle (mortise view) 1 Patient position. 2 Technical factors. 3 Image technical evaluation. The lateral and medial malleoli of the distal fibula and tibia,… 4 Practical points. In Australia, the mortise view is part of a three-part ankle series,…
How to get a better view of the ankle mortise?
Mortise view : To obtain a better view of the ankle mortise, the patient’s leg must be internally rotated just enough so that the lateral malleolus (which is normally posterior to the medial malleolus), is on the same horizontal plane as the medial malleolus, and a line drawn through both malleoli would be parallel to the tabletop.
Which is the best view of AP mortise?
AP mortise view The AP mortise view is done with the leg internally rotated 15-20oso that the x-ray beam is perpendicular to the inter-malleolar line. This view permits examination of the articular space (clear space).
Where does the strength of a mortise come from?
The strength in mortise and tenon joints comes from fitting one piece of wood, the tenon, into a slot, or mortise, in another piece of wood. A mortise is a cavity or hole that is cut into wood or stone, and is specially intended to receive a tenon, or protrusion, on another piece of wood or stone.
