Proximal fractures of 5th metatarsal. The tuberosity avulsion fracture (also known as pseudo-Jones fracture or dancer's fracture [2] is a common fracture of the fifth metatarsal (the bone on the outside edge of the foot extending to the little toe). [3] This fracture is likely caused by the lateral band of the plantar aponeurosis (tendon). [4]
The Maisonneuve fracture generally follows a specific pattern of injury. The following are described as subsequent events that result in a Maisonneuve fracture: [3] [4] [12] Forceful, external rotation of the ankle joint results in the tearing of the deep deltoid ligament and/or an avulsion fracture of the medial malleolus.
The os trigonum or accessory talus represents a failure of fusion of the lateral tubercle of the posterior process of the talus bone. Is estimated to be present in 7–25% of adults. [17] It can be mistaken for an avulsion fracture of lateral tubercle of talus (Shepherd fracture) or a fracture of the Stieda process. In most cases, Os Trigonum ...
One with a broken talus may not be able to walk for many months without crutches and will further wear a walking cast or boot of some kind after that. Talus injuries may be difficult to recognize, [9] [10] and lateral process fractures in particular may be radiographically occult. If not recognized and managed appropriately, a talus fracture ...
The calcaneonavicular ligament (ligamentum calcaneonaviculare) is attached to the lateral side of the navicular. (Note this is NOT the spring ligament which is commonly called the plantar calcaneonavicular ligament). It is commonly injured in "sprain-type" inversion injuries producing an avulsion fracture at the anterolateral process of the ...

While cuneiform fractures are fairly rare, the most commonly fractured cuneiform bone is the Medial cuneiform, typically the cause of a cuneiform fracture is by physical trauma (direct blow) to the cuneiform, as well as the result of an avulsion fracture and a result of axial load, [5] but can also be the result of a stress reaction that progressed with continued weight-bearing and physical ...
Figure 6: Subtle anterior talar fracture in a 39-year-old man presenting with ankle pain after a fall. (a) Anteroposterior radiograph shows a subtle oblique radiolucent line through the talus (white arrows). (b) Sagittal CT reformation confirms the presence of an anterior talar fracture with cortical offset (black arrow).
