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.
What is normal calcaneal inclination angle?
It is a measurement that reflects the height of the foot framework, but is affected by abnormal pronation or supination of the foot: low: 10-20° – indicative of pes planus when <18° medium: 20-30° – i.e. normal.
What is angle of Gissane?
Gissane angle, also known as the “critical angle”, is an angular measurement made directly inferior to the lateral process of the talus. It is formed by the downward and upward slopes of the calcaneal superior surface. It is better seen on a lateral plain film of the calcaneus and hindfoot.
In which type of fracture the tuber joint angle is reduced to?
Objectives: Bohler’s tuber joint angle is commonly assessed when evaluating calcaneal fractures. A severe heel fracture will result in a significant decrease or loss of this angle.
Why is it called Lover’s fracture?
The name “lover’s fracture” is derived from the fact that a suitor may jump from great heights while trying to escape from the lover’s spouse 2. There is an important association between lover’s fractures and burst fractures of the lumbar spine.
What is calcaneus 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 the talar declination angle?
The talar declination angle (TDA) is defined as the resultant angulation between the supporting surface and the longitudinal axis of the talar head and neck.
What is Lover’s fracture?
Lover’s fracture, also known as Don Juan fracture or Casanova fracture is a type of calcaneal fracture. They are fractures of the calcaneal body and may be intra- or extra-articular.
What causes a calcaneal stress fracture?
What causes Calcaneal Stress Fracture? A broken heel bone usually happens due to an acute, high-stress injury like a motor vehicle accident, a fall from a high position, or a traumatic twist of the ankle.
What is Bohler’s angle in the ankle?
Bohler’s angle (also sometimes referred to as the “Tuber Angle”) is formed by the intersection of lines 1 and line 2 on the lateral ankle radiograph. The normal range is 20 to 40 degrees. Angles < 20 degrees is suggestive of a calcaneus fracture and/or disruption of the posterior facet.
What are the signs and symptoms of pes planus?
Pes planus, in contradistinction, will show: loss of the normal straight line relationship. a sag at the talonavicular joint or naviculocuneiform joint. angle of the longitudinal arch increased to greater than 170 degrees.
What is Flatfoot (pes planus)?
Pes planus (also called flatfoot) is a deformity of the foot where the longitudinal arch of the foot is abnormally flattened.
What is the pathophysiology of pes planus in contradistinction?
Pes planus, in contradistinction, will show: loss of the normal straight line relationship a sag at the talonavicular joint or naviculocuneiform joint angle of the longitudinal arch increased to greater than 170 degrees
