The use of computed tomography (CT) can be helpful in high-energy injuries, as it can more precisely delineate complex fracture patterns, the geometry of the talonavicular joint, and can assist in preoperative planning. The navicular is one of the tarsal bones in the ankle. 3 Conservative therapy usually entails variable periods of rest with corrective trimming and shoeing to immobilize the hoof. Slight swelling may or may not be present. A retrospective review of twenty-one cases. The second issue is the blood supply to the bone, particularly the central area of the bone where these stress fractures tend to occur. In athletes, navicular stress fractures are of particular concern because they are underdiagnosed and can lead to significant disability if the diagnosis is delayed 25). Other risk factors include improper training techniques and consistently running on hard surfaces. They also occur in the wrist, as one of the eight carpal bones at the base of the hand is also known as the scaphoid or navicular bone. This arch provides support for normal gait, in particular from mid stance until push-off. Tenderness at the midmedial arch over the navicular, Pain that is often reproduced if the patient hops while in the equinus position.

The goals of operative intervention are anatomic fracture reduction, restoration of the length of the medial column, and creation of a rigid osseous construct which would allow for early range of motion 48). Track and field – Particularly sports involving jumping and sprinting. A jumper is a great way to keep your baby engaged while giving yourself a much-deserved moment to relax. Navicular fractures in the foot are generally a result of repetitive stress, whereas the injury in the wrist is generally caused by trauma. In a study by Torg et al 26) in 1982, the average time between the fracture and diagnosis was estimated to be 7 months. Mann JA, Pedowitz DI. Tarsal navicular stress fractures. Although no trials support the use of bone growth stimulators for navicular stress fractures, they may be a helpful adjunct 55). 22. Risk factors for stress fractures in track and field athletes. A navicular stress fracture is an injury is often seen in athletes due to overuse or trauma. Stress fractures are most common in young individuals with high functional demand such as competitive athletes 20).

Similar to an injury occurring in your foot, it may be difficult to determine the extent of the injury, as outward signs are minimal. The Sangeorzen classification system classifies tarsal navicular body fractures according to the direction of the fracture line, degree of disruption of surrounding joints, and the direction of foot displacement 23). The navicular is part of 2 important structures that are essential for normal gait: (1) the medial longitudinal arch and (2) the transverse tarsal joint (also called the midtarsal or Chopart joint). In the case of traumatic navicular injuries, the vast majority result from motor vehicle accidents, followed by falls and blunt injuries 19). All navicular body fractures with 1 mm or more of displacement require open reduction and internal fixation.

A navicular fracture can be difficult to detect because there are usually minimal outward signs of injury such as swelling or deformity. Smoking, low physical activity and poor nutritional status are also known risk factors for stress fractures. In evaluating radiographs, the clinician should be aware of the potential for the appearance of an accessory navicular, which is identifiable with a radiograph of the contralateral foot. Displaced intra-articular fractures of the tarsal navicular. A complete fracture with wide separation may benefit from early surgical intervention. A triple-phase bone scan is highly sensitive and has a high positive predictive value for stress fractures in the navicular, showing uptake on all phases (13). 1989 Dec. 71(10):1504-10. Complications may include nonunion of the fracture, avascular necrosis, and arthritis.. Scaphoid fractures are most commonly caused by a fall on an outstretched hand. Most physicians do not recommend immediate open surgical procedures when treating uncomplicated navicular stress fractures.  In particular, bone growth stimulators that use pulsed electromagnetic fields (PEMFs) have been shown to have similar success rates when compared with open repair in tibial fracture nonunions. Located in the middle of the foot, high compressive forces are focused on this bone, particularly when the foot strikes the ground. A stepwise regimen for the course of activity is as follows: Therapeutic Ultrasound may have a role in determining return to play decisions as pain with therapeutic ultrasound has corelated with MRI finding in navicular stress injuries 49).

The navicular is covered by cartilage and lacks a rich blood supply, especially at its center. Skeletal effects of menstrual disturbances in athletes. The transverse tarsal joint is essential for normal gait and is composed of the talonavicular joint and the calcaneocuboid joint. Palmar digital neurectomy often is required after the fracture heals to increase soundness. Midfoot fractures only represent a small portion of all foot injuries, though stress fractures comprise approximately one-third of all stress fractures of the foot 14). The navicular bone is in the ankle and can be fractured by overuse and repetitive stress. Clin J Sport Med. Acute fractures of the tarsal navicular.

Otherwise, a non-union where the bone doesn’t heal may occur or a process called avascular necrosis may develop. Fractures of the navicular body are commonly associated with other injuries of the midtarsal joint. Navicular bone is an essential component of the Chopart joint, which itself consists of the talonavicular and calcaneocuboid joints 13). Navicular fracture also called tarsal navicular fracture, most commonly the result of either traumatic injury or undue stress, with the latter having a higher incidence in younger individuals and athletes 1). However, patients with suspected ligamentous injury or minor injuries may require a weight-bearing radiograph. Navicular stress fractures (NSF) are uncommon but serious injuries, characterized by a chronic midfoot ache at the top of the arch of the foot in front of the ankle. Starting a second sport and assuming that the body is conditioned to participate at that sport immediately and at a high level. If the navicular is unstable, then internal fixation is required.

Symptoms generally includes pain at the base of the thumb which is worse with use of the hand. Navicular fractures are at high risk of nonunion and osteonecrosis owing to the navicular bone’s tenuous blood supply as well as the inherent complexity of the joint 3). Repetitive stress to the navicular bone can cause a thin crack or break that gradually increases with continued use. Whether these results are applicable to acute fractures and fractures of the navicular remains to be determined. Fractures of the midfoot and forefoot. However, if tenderness is not present at the N spot, then weight-bearing activity may begin.
