A small medial incision is made to facilitate placement of the more proximal screws. In plating, we can avoid extensive dissection by sliding subcutaneously the contoured plate along the medial aspect of the navicular. Stress fractures of the navicular, although uncommon, carry a high risk of morbidity related to misdiagnosis and subsequent fracture with nonunion. 2016 2017 2018 2019 2020 2021 2022 Billable/Specific Code. frx of body of navicular may be associated w/ mid-tarsal joint injuries - classification: 3 types: - coronal plane fracture w/ no angulation of the. Navicular fractures are classified as dorsal avulsion fractures, tuberosity fractures, and body fractures. Instead of a bridging plate, one can also leave the distractor or an external fixator in its place. Displaced fracture of navicular scaphoid of right foot, initial encounter for closed fracture. In the case of severely comminuted fractures where stable / rigid internal fixation is not possible, the medial column distractor is replaced by means of a bridging plate. This can also be accomplished by contouring non variable-angle locking plates, or using non-locking plates. These forces initially cause a bone stress reaction and continuous damage. The navicular was then pinned from the medial and intermediate cuneiform, through the navicular, into the talus with two smooth 2. Like all the other stress fractures, this overuse injury is a result of excessive and repetitive compressive forces that act on it during the weight bearing process. These navicular screws were placed through two small medial stab incisions.
NAVICULAR FRACTURE CRACK
If one is using the new generation of navicular plates, which provide the variable-angle screw insertion, the screws should be aimed distally, away from the talonavicular joint. Navicular stress fracture is an injury marked by an incomplete crack in one of the mid-foot bones.
When inserting the screws (in the proximal row, adjacent to the talonavicular joint), care must be taken to prevent the screws from entering the dome-shaped joint. This type of fracture occurs most often after a fall onto an outstretched. This plate is contoured and any extra holes are removed. A scaphoid (navicular) fracture is a break in one of the small bones of the wrist. A CT scan is useful to define the fracture a. Often, we need MRI to see swelling and a break in the bone. Usually, X-rays do not detect navicular stress fractures.
Sometimes, there is stiffness in the ankle and mild focal swelling in the mid-foot. The fractured navicular is secured at the end once reduced with a special navicular plate. We suspect a navicular stress fracture if there is tenderness at the body of the navicular bone.
