It's important for connecting the ankle to the lower bones in our feet and helps form the arch that enables us to walk. Trauma. Bones and Joints. J Bone Joint Surg Am. When A Patient Has A Complete Fracture. Because of its complex anatomy and blood supply, the tarsal navicular is susceptible to osteonecrosis, and injury to this bone can lead to posttraumatic arthrosis of the surrounding joints. Tarsal Navicular Fractures are rare fractures of the midfoot that may occur due to trauma or due to repetitive microstress. 26. Acute avulsion, tuberosity, and body fractures The most frequently in- Anatomy have been described. The tarsal navicular bone is the keystone of the medial column of the foot, bearing the majority of the load applied to the tarsal complex during weight-bearing [ 1,2 ]. Acute fractures of the tarsal navicular are uncommon, and isolated fractures are even more uncommon, as tarsal navicular injury is typically associated with other fractures, dislocations, or soft tissue injuries of the foot. Acute fractures of the tarsal navicular. Tarsal navicular stress fractures were first described in 1958 in a study of racing grey-hounds. Stress fractures of the tarsal bones, particularly the navicular, constitute approximately 20% of stress fractures in runners; although, the majority are identified in sprinters.3,38 The navicular is vulnerable to stress fractures due to limited vascularity, which also diminishes healing. Plain radiographs are the best initial test in a suspected navicular fracture. The navicular is the anatomical name given to one of the bones in the mid-foot. Normal function of the foot is lost and there will be tenderness over a specific area depending on which bone is broken. As such, injuries to … In addition, an avulsion fracture of the tuberosity of the navicular was found with slight distraction of a crescentic bony fragment (Fig. Figure 2. A muscle (known as the tibialis posterior) attaches to the navicular bone. Fractures of the tarsal navicular are relatively uncommon, and generally are a result of acute trauma or chronic overload in the form of stress fractures.

Fractures of the tarsal bone, such as the navicular, cuboid, and cuneiform, are very rare. The most commonly used classification for navicular fractures rely on the mechanism of injury of the fracture [ [ii] ]: - Tuberosity fracture - avulsion injuries; often the result of an acute eversion or valgus injury to the forefoot (increased stress on the PT tendon) Search within full text. Stress fractures and insufficiency fractures occur frequently in the ankle and foot and predominantly involve the second metatarsal, the calcaneus, and, less frequently, the navicular bone and talus (, 41–, 44). Rev Chir Orthop Reparatrice Appar Mot. Symptoms of a tarsal fracture include sudden pain from a force or impact and difficulty bearing weight. The navicular is a tarsal bone that is part of 2 structures essential for normal gait . A navicular body fracture, either isolated or with additional fractures, dislocations, and/or fracture-dislocations of the foot [combination injuries (CIs)], is an uncommon injury and results from a high-energy crush or dislocation. » Radiographs usually are sufficient for the diagnosis and treatment of tarsal navicular fractures. Navicular fracture. Open fractures require immediate IV antibiotics and urgent surgical washout. Their importance arise from being somewhat difficult to detect, and if missed can result in significant morbidity with midfoot arthrosis, especially since its complex anatomy and blood supply make the navicular susceptible to osteonecrosis. Bojanic I. A navicular stress fracture is a condition characterized by an incomplete crack in the navicular bone. Fractures of the body result from high- jured lesser tarsal bone is the The navicular derives its energy trauma and are often seen in conjunction with addi- navicular, a vital component name from its resemblance to tional ipsilateral foot injuries. Axial CT of the right foot (A, B) with sagittal (C) and 3-D (D) reformations. Approximate Synonyms. This is a picture showing how custom orthotics can support the navicular stress fracture site. It is prone to stress fractures, especially by athletes while kicking, sprinting, twisting, or … Treatment is generally nonoperative with cast immobilization and non weight-bearing for the majority of fractures. Once considered a rare form of stress fractures, navicular stress fractures 1). Bookmarks (0) Musculoskeletal. doi: 10.3928/01477447-20140728-07. PMID: 25102497.

Nine navicular fractures were seen in 175 fractures reviewed from the Cincinnati Children’s Hospital. Diagnosis can be made with plain radiographs of the foot. Classically, Main and Jowett 1 first described the injury. Navicular fractures are usually avulsion injuries that occur with an inversion/plantarflexion mechanism. Their sensitivity for identifying navicular fracture is low, however lateral and oblique radiographs provide the greatest chance of identifying a fracture. Acute avulsion, tuberosity, and body fractures have been described. Calcaneus fractures make up the majority of tarsal fractures and usually occur with falls from heights. This is a comment on "Displaced intra-articular fractures of the tarsal navicular. " Fractures of the tarsal navicular are commonly the result of trauma or chronic overload.

The tarsal navicular plays an integral role in hind-foot motion and gait, and is the keystone of the foot's medial longitudinal arch. Physicians normally see this injury pattern with an acute traumatic event or in cases of a chronic stress reaction of the navicular. 27. The navicular bone is one of the 26 bones in the human foot. Complete fractures of the tarsal navicular. However, there is little literature reporting results of this treatment and correlation to fracture severity. The patient's history of navicular fracture of the tarsal navicular did not have an acute traumatic aetiology. Therefore, repeated stress to the medial side of the tarsal navicular, which touched the floor directly, was considered to have caused the tarsal navicular fracture. A possible deformity in traumatic fractures may also be seen. Because of the variability in ossification, a fracture may be confused with Köhler disease. Similar bone scan findings are seen in other conditions involving the navicular such as acute fractures, symptomatic accessory navicular, tarsal coalition, anterior or posterior tibial tendinosis, neoplasms and osteomyelitis. With these 2 midfoot injuries, the exam should include palpation of the cuboid, navicular, and cuneiform bones and careful inspection of the Lisfranc joint, as this can be injured in midfoot fractures. Stress fractures are also reported.Avulsion fracture, the most common fracture of the navicular, is often associated with ligamentous injuries and results from twisting forces on the mid foot.
