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 dorsal talonavicular ligament extends from the dorsal aspect of the foot from the neck of the talus to the navicular. [ 1 ] [ 2 ] The socket of this joint is formed by the concave articular facets of the navicular, calcaneus, calcaneonavicular part of bifurcate ligament and the spring ligament (plantar calcaneonavicular ligament), where the ...
Treatment comprises early reduction of the dislocation, and frequently involves open reduction internal fixation to restore and stabilise the talonavicular joint. Open reduction and fusion of the calcaneocuboid joint is occasionally required. [3]
The transverse tarsal joint or midtarsal joint or Chopart's joint is formed by the articulation of the calcaneus with the cuboid (the calcaneocuboid joint), and the articulation of the talus with the navicular (the talocalcaneonavicular joint).
Spinal fusion, also called spondylodesis or spondylosyndesis, is a surgery performed by orthopaedic surgeons or neurosurgeons that joins two or more vertebrae. [1] This procedure can be performed at any level in the spine (cervical, thoracic, lumbar, or sacral) and prevents any movement between the fused vertebrae.
The rate of reoperation was 22%, with screw removal done in 11.4%, nail removal done in 4.2%, revision fusion done in 3.4%, and amputation in 1.5%. [11] The review concluded that there is a good fusion rate with TTC arthrodesis using an IM nail but that the surgery has a high rate of complications. [ 11 ]
The dorsal talonavicular ligament is a broad, thin band, which connects the neck of the talus to the dorsal surface of the navicular bone; it is covered by the Extensor tendons. The plantar calcaneonavicular supplies the place of a plantar ligament for this joint.
The talonavicular coverage angle is abnormally laterally rotated in flat feet. [11] It is normally up to 7 degrees laterally rotated, so a greater rotation indicates flat feet. [ 11 ] Radiographies generally need to be taken on weightbearing feet in order to detect misalignment.
