Calcaneus

The video tutorial provides an in-depth exploration of the calcaneus, the largest foot bone, detailing its joints, surfaces, and bony landmarks. It covers the muscles and ligaments that attach to the calcaneus, emphasizing their roles in foot movement and stability. The tutorial concludes with a clinical case study of a calcaneus fracture, discussing symptoms, diagnosis, and treatment options.

What is the primary function of the calcaneus in the human body?

• To form the upper ankle joint

• To connect the tibia and fibula

• To support the body's weight and stabilize balance

• To protect the Achilles tendon

Which bone is directly ventral to the calcaneus?

• OS Cuboideum

• Tibia

• Talus

• OS Naviculare

What is the function of the Carga fat body?

• To support gliding movements of the Achilles tendon

• To form the lower ankle joint

• To protect the patellar tendon

• To connect the calcaneus to the talus

Which muscle originates from the posterior articular surface of the calcaneus?

• Abductor hallucis

• Extensor digitorum brevis

• Quadratus plantae

• Flexor hallucis longus

What is the primary role of the plantar aponeurosis?

• To form the upper ankle joint

• To connect the calcaneus to the talus

• To cover and protect the sole's muscles, blood vessels, and nerves

• To protect the Achilles tendon

What is a common cause of calcaneus fractures?

• Genetic predisposition

• High-impact trauma like a fall

• Chronic inflammation

• Infection

What is the typical symptom progression for a calcaneus fracture?

• Immediate severe pain and swelling

• Gradual development of symptoms over days or weeks

• Sudden loss of foot function

• Immediate bruising and discoloration

What is the primary consideration for treating an extra-articular calcaneus fracture?

• Immediate surgical intervention

• Use of anti-inflammatory medication

• Immobilization in a lower leg plaster

• Physical therapy

Which imaging technique is recommended for diagnosing a calcaneus fracture?

• Bone scan

• X-ray or CT scan

• Ultrasound

• MRI

What is the role of the triceps surae muscle in relation to the calcaneus?

• It originates from the calcaneus

• It inserts into the calcaneus via the Achilles tendon

• It stabilizes the calcaneus

• It protects the calcaneus from fractures
