$navicular stress fracture symptoms$

Small observational and laboratory studies suggest that certain anatomic variants may place greater stress on the tarsal navicular during running, thereby increasing the risk for stress fracture. However, these fractures have been reported in military recruits and participants in soccer (football), Australian rules football, and jumping sports (eg, basketball). In one retrospective study of 180 high-level athletes with stress fractures, 59 percent of all tarsal navicular stress fractures occurred in track athletes and the majority of these were found among distance runners. (See 'Overview of stress fractures', section on 'Risk factors'.)Īthletes who participate in track and running sports, including sprinters and hurdlers, are especially prone to navicular stress fracture. The general risk factors for stress fractures are reviewed in detail separately. Delays in treatment result in poorer outcomes compared with injuries diagnosed and treated promptly. Of note, up to 30 percent of tarsal navicular stress fractures are missed primarily or are treated in a delayed manner. Female athletes appear to be at greater risk. Overuse or excessive mechanical stress due to improper training programs, poor equipment (eg, worn running shoes, hard surfaces), improper running technique, and anatomic variants may all increase the risk for navicular stress fracture.

Navicular stress fractures are seen in elite and recreational athletes, and in military personnel, with an average patient age at the time of injury of 25 to 29 years. (See 'Tarsometatarsal (Lisfranc) joint complex injuries' and 'Metatarsal shaft fractures' and 'Proximal fifth metatarsal fractures' and 'Evaluation and diagnosis of common causes of midfoot pain in adults' and 'Talus fractures' and 'Fibula fractures' and 'Ankle fractures in adults'.)ĮPIDEMIOLOGY AND RISK FACTORS - Stress fractures of the tarsal navicular are relatively common, comprising approximately 10 to 35 percent of all foot and ankle stress fractures. Acute fractures to the tarsal navicular and injuries of the other tarsal bones, ankle, and leg are discussed separately. The presentation, diagnosis, and management of tarsal navicular stress fractures is reviewed here.

Delay in diagnosis is particularly problematic with navicular stress fractures, which at baseline are at increased risk of nonunion. The absence of acute trauma, relatively low level of pain, minimal swelling, inconsistent examination findings, and the difficulty identifying these fractures on routine radiographs all combine to make stress fractures of the navicular one of the most commonly missed or delayed diagnoses in the foot. Among athletes involved in cutting, pivoting, and especially running sports, stress fractures of the tarsal navicular are an important cause of midfoot pain.

The biomechanical and vascular properties of the navicular make it susceptible to stress fracture. INTRODUCTION - 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 weightbearing.
