How can Sustentaculum Tali be injured?
Osteitis of the Sustentaculum Tali Injury usually occurs from direct trauma, most commonly from a kick wound. Lameness is often severe. Diagnosis can be difficult because of the severe soft tissue swelling that accompanies this injury, especially when acute.
Are calcaneus fractures common?
Calcaneus fractures are uncommon. Fractures of the tarsal bones account for only about 2% of all adult fractures and only half of tarsal fractures are calcaneus fractures. A fracture may cause the heel bone to widen and shorten. In some cases, a fracture may also enter the subtalar joint in the foot.
What is the talus bone?
The talus is a small bone that sits between the heel bone (calcaneus) and the two bones of the lower leg (the tibia and fibula). It has an irregular, humped shape like a turtle’s shell. The bones of the lower leg ride on top and around the sides to form the ankle joint.
What runs under sustentaculum tali?
The flexor hallucis longus is a muscle arising in the calf. Its tendon passes behind the medial malleolus of the ankle, and enters the sole in its medial side. It lies in the bony groove on the inferior surface of sustentaculum tali of the calcaneus as it enters the sole (see Fig.
What is sustentaculum tali fracture?
Fractures of the sustentaculum tali are rare injuries that often occur in conjunction with ipsilateral foot and ankle injuries. Displaced sustentacular fractures can be safely approached from the medial aspect of the heel, retracting the neurovascular bundle distally.
Can you walk on a talus fracture?
You should be able to walk on it, but not without pain. Displaced. The pain, swelling, and tenderness are greater. You may not be able to put weight on the injured ankle.
What muscles attach to sustentaculum tali?
On the margin of the sustentaculum tali are the attachments of the tendon of flexor digitorum longus and the large medial head of flexor accessorius is attached distal to the groove for flexor hallucis longus.
What does the Sustentaculum do?
At the upper and forepart of the medial surface of the calcaneus is a horizontal eminence, the sustentaculum tali, which gives attachment to a slip of the tendon of the Tibialis posterior.
What are the characteristics of fractures of the sustentaculum tali?
Fractures of the sustentaculum tali: injury characteristics and surgical technique for reduction Fractures of the sustentaculum tali are rare injuries associated with high energy mechanisms, and associated ipsilateral foot injuries are common.
Is internal fixation possible for ipsilateral sustentaculum tali fractures?
Fractures of the sustentaculum tali are rare injuries associated with high energy mechanisms, and associated ipsilateral foot injuries are common. Open reduction and internal fixation of these fractures was reliable and possible through a medial approach involving distal retraction of the digital fl …
What is the AOFAS score for a sustentaculum fracture?
At the time of follow-up, 15 sustentaculum tali fractures had an average Foot Function Index of 21.6 and an average AOFAS Ankle-Hindfoot Score of 83.6. Patients with isolated fractures of the sustentaculum tali had significantly better scores than those with additional injuries.
Why is the medial plate buttressing the sustentacular fragment?
The medial plate is buttressing the sustentacular fragment which was first reduced and fixed with a lag screw. The compression provided absolute stability. The medial plate in the buttress position prevents axial displacement.
