Chopart fracture-dislocations occur at the midtarsal (Chopart) joint in the foot, i.e. talonavicular and calcaneocuboid joints which separate the hindfoot from the midfoot. The commonly fractured bones are the calcaneus, cuboid and navicular.
What is a Chopart joint injury?
Midtarsal sprains reflect a spectrum of injuries resulting from low-energy trauma to the Chopart joint complex and include both soft-tissue capsuloligamentous injuries and osseous injuries, including ligament sprains or tears, as well as avulsion or impaction fractures, depending on the severity and mechanism of injury ...
What is a nutcracker fracture?
A nutcracker fracture of the cuboid refers to a cuboid bone fracture with associated navicular avulsion fracture due to compression between the bases of 4th and 5th metatarsals and calcaneus bone. The injury usually occurs secondary to the traumatic abduction of the forefoot.
What joints make up the Midtarsal joint?
The midtarsal joint (MTJt) consists of the combined articulations of the talonavicular and calcaneocuboid joints and represents the functional articulation between the rearfoot (talus and calcaneus) and the midfoot (navicular and cuboid).
What is a Lisfranc dislocation?
A Lisfranc dislocation or injury typically describes a spectrum of injuries involving the tarsometatarsal joints of the foot. The Lisfranc joint itself is composed of the articulation between the first, second, and third metatarsals bones, and the cuneiform bones.
What is a Segond fracture?
Segond fracture is an avulsion fracture of the knee that involves the lateral aspect of the tibial plateau and is very frequently (~75% of cases) associated with disruption of the anterior cruciate ligament (ACL).
Why is it called Nutcracker fracture?
Compressed fracture of the cuboid was named “nutcracker” fracture by Hermel and Gershon-Cohen. It results from forced plantar flexion and abduction, crushing the cuboid between the calcaneus and fourth and fifth metatarsals.
What type of joint is between Tarsals?
intertarsal joints The joints of the foot are made wherever two or more of the foot bones meet. The joints between the tarsal bones of the foot are known as the intertarsal joints.
How do you treat a Segond fracture?
Patients underwent direct Segond fracture repair by either suture alone, suture anchor, or cannulated screw fixation based on the size of the lesion, followed by a 2-incision hamstring autograft intra-articular reconstruction.
What causes a Segond fracture?
Classically resulting from internal rotation and varus stress of the knee in flexion, the Segond fracture is an avulsion injury of the lateral tibial plateau and midlateral capsule that frequently accompanies ACL rupture. This injury commonly includes meniscal injury.
How do I know if I broke my cuboid bone?
Symptoms of a cuboid fracture include bruising, tenderness, swelling, lateral foot pain, instability, and difficulty with weight bearing. Cuboid fractures have the potential to cause considerable deformity involving the foot arch, lateral column, and the function of the forefoot.
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.
