What is a displaced intra-articular calcaneal fracture?
The calcaneus is the most commonly fractured tarsal bone. Displaced intraarticular calcaneal fractures are usually caused by a fall from height with one or both heels directly hitting the ground. Displaced intra-articular calcaneal fractures are complex and highly disabling injuries.
Which bone fracture is evaluated by Bohler’s angle?
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.
What is the anterior process of the calcaneus?
The anterior process of the calcaneus is a prominence on the heel bone (calcaneus) that is located in front and to the outside of the ankle (Figure 1). Fractures of the anterior process of the calcaneus occur following an acute injury to the foot.
What is a tongue type calcaneal fracture?
Tongue-type calcaneus fractures are longitudinal fractures that exit the calcaneal tuberosity posteriorly and involve a portion of the articular surface. They are often superiorly displaced because of the insertion of the Achilles tendon and pull of the gastroc-soleus complex.
How is calcaneal pitch measured?
- The calcaneal inclination axis, extending from the calcaneus by the inferior portion of the calcaneocuboid joint to the inferior border of the calcaneus.
- Tangential to the inferior distal border of the calcaneus.
Does a calcaneus fracture require surgery?
Some, but not all, calcaneus fractures require surgery. The broken bone will take 3-4 months to heal with or without surgery. If surgery is not needed, there will still be a time where movement and weight bearing is limited.
Is subtalar arthritis painful?
Subtalar arthritis is a type of arthritis which affects the subtalar joint, that is, the joint found below the ankle joint in the hindfoot. The condition is characterised by pain in the hindfoot area, which can be aggravated by walking, especially on an uneven surface, and standing.
What fracture is associated with calcaneus fracture?
Extraarticular fractures account for 25 % of calcaneal fractures. These typically are avulsion injuries of either the calcaneal tuberosity from the Achilles tendon, the anterior process from the bifurcate ligament, or the sustentaculum tali. Intraarticular Fractures account for the remaining 75%.
What is normal calcaneal pitch angle?
Unfortunately, there have been differing opinions between authors concerning the normal range of calcaneal pitch 18–32° is generally considered normal, although measurements reporting a calcaneal pitch with angle minor than 18° represent a flatfoot syndrome.
Does Böhler’s angle affect the severity of Displaced intra-articular calcaneal fractures?
There was a significant correlation between preoperative Böhler’s angle and the injury severity of displaced intra-articular calcaneal fractures, but only postoperative Böhler’s angle parameters were found to have a significant correlation with the functional recovery.
What is the prevalence of disdisplaced intra-articular calcaneal fractures?
Displaced intra-articular calcaneal fractures constitute 70% of all calcaneus fractures in adults. Böhler’s angle is frequently assessed when evaluating this type of fractures on lateral plain X-ray films.
What are the radiographic parameters used to describe calcaneal fractures?
Various radiographic parameters have been used to describe calcaneal fractures. Böhler’s angle is an accepted method of quantifying fracture displacement and has a prognostic value in predicting morbidity associated with calcaneal fractures. Mitchell et al.
Can postoperative Böhler’s angle predict clinical outcomes?
Our findings support the former viewpoint that postoperative Böhler’s angle can be used to predict the clinical outcomes. We found a significant positive correlation between postoperative Böhler’s angles and American Orthopaedic Foot & Ankle Society hindfoot scores.
