What is Gissane angle?

What is Gissane angle?

The Gissane (crucial) angle is formed by two strong cortical struts extending laterally, one along the lateral margin of the posterior facet and the other extending anterior to the beak of the calcaneus.

How do you find the angle of Gissane?

The Gissane angle is measured by drawing lines along the superior surfaces of the anterior process and the posterior facet of the calcaneus to meet at the calcaneal sulcus 1.

What is Bohler angle?

Böhler’s angle is defined by two intersecting lines: one drawn from anterior process of the calcaneus to the highest part of posterior articular surface and a second drawn from the same point of posterior articular surface to the most superior point of tuberosity.

Where is the calcaneal tuberosity?

On the lateral side is commonly a tubercle called the calcaneal tubercle (or trochlear process). This is a raised projection located between the tendons of the peroneus longus and brevis. It separates the two oblique grooves of the lateral surface of the calcaneus (for the tendons of the peroneal muscles).

Where is the talocalcaneal joint?

The subtalar joint, also known as the talocalcaneal joint, forms a bridge between the foot and ankle. Located in the hindfoot, it’s the point at which the calcaneus (heel bone) and the talus (a bone at the lower part of the ankle joint) meet.

What is Talocalcaneal ligament?

The lateral talocalcaneal ligament (LTCL) is a short yet sturdy bundle of muscle fibers found in the human ankle. The lateral talocalcaneal ligament stretches from the lateral (outer-side) portion of the talus, or ankle bone, to the lateral surface of the calcaneus, or heel bone.

What type of bone is calcaneus?

The calcaneus is an irregular bone, cuboid in shape whose superior surface can be divided into three areas – the posterior, middle and anterior aspects.

What attaches to calcaneal tuberosity?

The Achilles tendon attaches to the calcaneal tubercle.
