Calcaneocuboid joint

Calcaneocuboid Joint

The calcaneocuboid joint is an important articulation in the foot, connecting the calcaneus bone (heel bone) and the cuboid bone. It is classified as a synovial joint, specifically a gliding joint, allowing for limited movement and providing stability to the foot.

Anatomy

The calcaneocuboid joint is located on the lateral side of the foot, between the calcaneus and the cuboid bones. It is part of the midfoot region, which plays a crucial role in weight-bearing and propulsion during walking and running.

The calcaneus bone is the largest bone in the foot, forming the heel. It has a prominent posterior tuberosity that serves as an attachment site for the Achilles tendon. The cuboid bone is located in the middle of the foot, on the lateral side. It is cube-shaped, hence its name, and articulates with multiple bones, including the calcaneus.

Function

The calcaneocuboid joint is involved in various movements of the foot, including inversion and eversion. Inversion refers to the movement of the sole of the foot towards the midline, while eversion refers to the movement of the sole away from the midline. These movements are important for maintaining balance and stability during walking and running.

Additionally, the calcaneocuboid joint plays a role in weight distribution and shock absorption. It helps to distribute the forces generated during weight-bearing activities, reducing the stress on other structures of the foot.

Clinical Significance

Injuries to the calcaneocuboid joint can occur due to trauma, repetitive stress, or underlying conditions such as arthritis. Common injuries include sprains, fractures, and dislocations. Symptoms may include pain, swelling, limited range of motion, and difficulty walking.

Treatment for calcaneocuboid joint injuries typically involves rest, immobilization, physical therapy, and in severe cases, surgical intervention. Rehabilitation exercises are crucial for restoring strength, flexibility, and function to the joint.
