What is a Harris view?
The Harris projection (also called the penetrated axial projection) is a special radiographic view that is used for assessment of talocalcaneal coalition.
How do you take Harris view?
To obtain the Harris view, the C-arm is rotated such that the beam is oriented parallel to the floor. With the surgeon standing in the center of the “C,” the base of the C-arm is advanced towards the posterior of the patient until the heel is adjacent to the x-ray source. Optimal axial imaging may then be obtained.
What is Harris Beath?
The Harris Beath projection is a specialized weightbearing foot x-ray to demonstrate the calcaneal body, middle facet of the subtalar joint, and the sustenaculum tali.

What is Talocalcaneal coalition?
Talocalcaneal coalition or peroneal spastic foot or subtalar coalition is an anomalous connection between the talus and the calcaneum that can present with painful and rigid flat-foot in older children and adolescents. The talocalcaneal coalition can be fibrous, cartilaginous, or bony.
How do you Xray the bottom of your foot?
Position of part IR under patient’s foot, parallel with its long axis, and center it to midline of foot at level of base of third metatarsal. Rotate leg laterally until plantar surface of foot forms an angle of 30 degrees to IR. Support elevated side of foot on a 30 degrees foam wedge to ensure consistent results.
What passes under Sustentaculum Tali?
At the upper and forepart of the medial surface of the calcaneus, below the middle talar facet, there is a horizontal eminence, the talar shelf (also sustentaculum tali), which gives attachment to the plantar calcaneonavicular (spring) ligament, tibiocalcaneal ligament, and medial talocalcaneal ligament.
What is calcaneal fracture?
A fracture of the calcaneus, or heel bone, can be a painful and disabling injury. This type of fracture commonly occurs during a high-energy event—such as a car crash or a fall from a ladder—when the heel is crushed under the weight of the body. When this occurs, the heel can widen, shorten, and become deformed.
What is talocalcaneal coalition?
What is subtalar joint?
Subtalar joint is made up of articulation between three joint surfaces inferiorly talus with three joint surfaces superiorly calcaneus (Fig. 23.14) (Drake et al., 2015; Bartonicek et al., 2018). Subtalar joint functions as a bridge between foot and ankle; transferring loads from foot to tibia or from tibia to foot.
What happens if tarsal coalition goes untreated?
What if tarsal coalition goes untreated? Over time, a child, teen, or young adult may experience enough pain that they can’t do the activities they enjoy. Later in life, they may have a very stiff foot (indicating a large coalition). The foot may be so stiff and painful that surgical repair is no longer an option.
What is Fibrocartilaginous Calcaneonavicular coalition?
A tarsal coalition is an abnormal connection that develops between two bones in the back of the foot (the tarsal bones). This abnormal connection, which can be composed of bone, cartilage or fibrous tissue, may lead to limited motion and pain in one or both feet.
