What are the joints of the foot?
The specific intertarsal joints of the foot include the subtalar joint, talocalcaneonavicular joint, calcaneocuboid joint, cuneonavicular joint, cuboideonavicular joint, and the intercuneiform joint.
How many articulations are in the foot?
Each foot is made up of 26 bones, 30 joints and more than 100 muscles, tendons and ligaments, all of which work together to provide support, balance and mobility.
What is the joint between leg and foot called?
Talocrural joint, or ankle joint, is formed between the tibia and fibula (bones of the lower leg) and the talus bone of the foot. It acts as a hinge joint, and allows for dorsiflexion (upward movement) and plantar flexion (downward movement).
What are toe joints called?
The metatarsal phalangeal joints are the joints between the metatarsals and the proximal phalanx of each toe. These joints form the ball of the foot. The first metatarsal phalangeal joint sits in line with the big toe.
What is tarsal joint?
The transverse tarsal joint, also referred to as the midtarsal or Chopart’s joint, crosses the foot horizontally in an S-shaped direction, connecting the hindfoot and midfoot. It is a compound joint composed of two smaller, synovial joints: talonavicular and calcaneocuboid articulations.
What is DIP and PIP joints?
The PIP and DIP joints are hinge joints between proximal and middle phalanges and between the middle and distal phalanges respectively. These PIP and DIP joints allow flexion and extension, which help in grasping, pinching, and clawing or reaching functions.
What is MP joint in foot?
The metatarsophalangeal joints (MTP joints), also informally known as toe knuckles, are the joints between the metatarsal bones of the foot and the proximal bones (proximal phalanges) of the toes.
What is a Tibiotalar joint?
The tibiotalar joint (Talocrural joint) The tibiotalar joint forms the junction between the distal tibia and fibula of the lower leg and the talus. The load-bearing aspect of this joint is the tibial-talar interface. The talus bone includes the head, neck and body, and has no direct muscle connection.
Where is metatarsal joint?
The metatarsophalangeal (MTP) joints are the links between your toes and the bones in the main part of your foot.
What are the 3 tarsal joints?
The transverse tarsal joint separates the rearfoot from the midfoot (see Fig. 11.1). This extensive joint consists of two separate articulations: the talonavicular joint and the calcaneocuboid joint. This pair of joints allows the midfoot to move independently of the rearfoot (i.e., the calcaneus and talus).
What is MCP joint?
The metacarpophalangeal (MCP) joints are diarthrodial joints where the large convex heads of the distal aspect of the metacarpals articulate with the concave-shaped proximal aspect of each phalange. The articulating surface of each metacarpal head and proximal phalange is composed of hyaline cartilage.
What is PIP joint?
The PIP joint is the middle joint of each of your fingers. It is a highly complex joint with many soft tissue structures surrounding the bones to enable your finger to move. It is commonly damaged during falls and ball sports.
Where is the talonavicular joint?
The talonavicular joint is a joint formed by the talus, the bottom half of the ankle joint, and the foot bone immediately in front of it called the navicular. The talonavicular joint is critical in allowing the foot to move inwards and outwards, as well as in a circular motion.
What are subtalar joints?
Subtalar joint is made up of articulation between three joint surfaces inferiorly talus with three joint surfaces superiorly calcaneus (Fig. 23.14) (Drake et al., 2015; Bartonicek et al., 2018). Subtalar joint functions as a bridge between foot and ankle; transferring loads from foot to tibia or from tibia to foot.
What are Condyloid joint?
The wrist joint also referred to as the radiocarpal joint is a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand. A condyloid joint is a modified ball and socket joint that allows for flexion, extension, abduction, and adduction movements.
