Triple arthrodesis is a surgical procedure whose purpose is to relieve pain in the rear part of the foot, improve stability of the foot, and in some cases correct deformity of the foot, by fusing of the three main joints of the hindfoot: the subtalar joint, calcaneocuboid joint and the talonavicular joint.
The bones of the tarsus are the rear most bones in the adjacent diagram: calcaneus, talus, navicular, cuboid, medial cuneiform, intermediate cuneiform and lateral cuneiform bones. [9] These bones create the two major foot joints – the subtalar and midtarsal joints – that allow complex motions to occur in the feet. These motions are ...
The complex motion of the subtalar joint occurs in three planes and produces subtalar inversion and eversion. Along with the transverse tarsal joint (i.e. talonavicular and calcaneocuboid joint), the subtalar joint transforms tibial rotation into forefoot supination and pronation. The axis of rotation in the joint is directed upward 42 degrees ...
The intertarsal joint are the joints of the tarsal bones in the foot. There are six specific inter tarsal joints (articulations) in the human foot: Subtalar joint; Talocalcaneonavicular joint; Calcaneocuboid joint; Cuneonavicular joint; Cuboideonavicular joint; Intercuneiform joints
The talus is then resected, and the foot is placed so that the lateral malleolus rests opposite the calcaneocuboid joint, and the medial malleolus lies just above and behind the navicular bone. The foot is held in place with a surgical pin or with Kirschner wire. After the operation, the patient wears an above-knee cast for six weeks, followed ...
The subtalar joint is particularly susceptible to arthritis, especially when it has previously been affected by sprains or fractures such as those of the calcaneum or talus. Symptoms of subtalar joint arthritis include pain when walking, loss of motion through the joint's range of motion, and difficulty walking on uneven surfaces.
Arthrodesis, also known as artificial ankylosis or syndesis, is the artificial induction of joint ossification between two bones by surgery.This is done to relieve intractable pain in a joint which cannot be managed by pain medication, splints, or other normally indicated treatments.
The main purpose of subtalar arthroereisis is to correct the excessive subtalar eversion and restore the subtalar joint to a more neutral position. [5] [6] This is achieved by inserting an implant, typically made of materials such as silicone or polyethylene, into the sinus tarsi or adjacent to it. The implant serves to provide stability and ...
