Intercuneiform joints

Intercuneiform joints are the joints that connect the three cuneiform bones of the foot. These joints are part of the tarsus, which is the cluster of seven articulating bones in each foot situated between the lower end of tibia and fibula of the lower leg and the metatarsus.

Etymology

The term "intercuneiform" is derived from the Latin words "inter", meaning between, and "cuneiform", meaning wedge-shaped. This refers to the location and shape of the bones that these joints connect.

Anatomy

The intercuneiform joints are plane joints, which allow for limited gliding movement. They are formed between the adjacent surfaces of the three cuneiform bones: the medial cuneiform bone, the intermediate cuneiform bone, and the lateral cuneiform bone. These bones are connected by dorsal, plantar, and interosseous ligaments.

Function

The intercuneiform joints, along with the other joints in the tarsus, contribute to the foot's ability to support the weight of the body and provide flexibility and mobility. They allow for limited movement between the cuneiform bones, which is important for the foot's ability to adapt to uneven surfaces and for the complex movements involved in walking and running.

Clinical significance

Injuries or conditions that affect the intercuneiform joints can cause foot pain and mobility issues. These may include arthritis, sprains, fractures, and dislocations. Treatment may involve rest, physical therapy, medication, or in severe cases, surgery.
