SUBTALAR JOINTS Meaning and
Definition
-
Subtalar joints, also known as talocalcaneal joints, are a pair of articulations located in the foot that play a crucial role in foot movements and stability. These joints connect the talus bone, which is the second largest bone in the foot, to the calcaneus bone, commonly known as the heel bone.
The subtalar joints are classed as synovial joints, characterized by a synovial membrane that produces a lubricating fluid to minimize friction and facilitate smooth movements. These joints are considered to be a combination of two types of synovial joints: a ball-and-socket joint and a gliding joint. The head of the talus bone acts as the ball, fitting into a socket-like depression on the upper surface of the calcaneus bone.
The primary function of the subtalar joints is to enable inversion and eversion movements of the foot. Inversion refers to the inward tilting of the foot, while eversion involves the outward tilting. These movements are essential for maintaining balance, stability, and shock absorption during walking, running, and various weight-bearing activities.
In addition to their role in foot movement, the subtalar joints also contribute to weight distribution and force transmission throughout the foot and lower extremities. They are closely connected to the ankle joint and the bones of the midfoot, forming an intricate network of joints that ensures proper weight distribution and efficient energy transfer during locomotion.
Injuries or abnormalities in the subtalar joints can lead to various foot problems, such as flat feet, instability, pain, and limited range of motion. Rehabilitation exercises, orthotics, and, in severe cases, surgical interventions may be utilized to address these conditions and restore proper function to the subtalar joints.

Etymology of SUBTALAR JOINTS
The word "subtalar" is derived from the Latin prefix "sub", meaning "under", and the Latin word "talus", which refers to the tarsal bone in the foot. The term "subtalar" describes something that is located or occurring below or beneath the talus bone. The word "joints" is from the Old French term "joint", which comes from the Latin word "junctus", meaning "joined" or "connected". So, "subtalar joints" refers to the joints that connect or join the bones beneath the talus, specifically the joints between the talus and the calcaneus (heel bone).
