![]() ![]() In many cases, a part of the navicular may be fractured due to ligament avulsion that occurs during the injury. These include crush injuries, falls from heights, and motor vehicle accidents. How Does a Navicular Bone Fracture Happen?Īcute navicular fractures can occur due to high-impact injuries to the foot. It’s important to understand the anatomy of the navicular bone, as this becomes important when it comes to the management of these fractures. This can make fractures that occur in this area at risk of not healing. However, the blood supply is limited in the central portion of the navicular bone. The navicular bone receives its blood supply from the anterior and posterior tibial arteries. In addition, the strong posterior tibial tendon that is responsible for holding up the foot and supporting the arch inserts at the navicular bone. Ligaments are also present that connect the navicular to adjacent bones. The navicular bone connects your ankle bone (talus) to the rest of the midfoot bones (cuneiform and cuboid bones). ![]() Throughout the whole recovery period, pain free strengthening and stretching exercises should be performed to maintain optimal conditions in the whole leg.The navicular bone is one of the important bones that make up the midfoot. There will also be a period of rehabilitation including a gradual return to activity (your physiotherapist will dictate the pace of this according to your presentation). Physiotherapy (when out of cast) will help mobilise stiff joints and strengthen weakened muscles throughout the limb. GENERAL TREATMENT Strict immobilisation and non weight bearing in a cast for up to 8weeks, and immobilisation should continue until there is no point tenderness. If the fracture is suspected, an X-Ray may help but is not very good at diagnosing this injury. If this is found then a fracture is suspected although further clinical examination should rule out other causes of the pain. In severe cases, the pain may be aggravated by just walking, and you may also experience pain at night (this is due to the healing processes at work as you are resting).ĪSSESSMENT INFORMATION Clinical questioning will highlight common signs and symptoms and any traumatic occurrences that may have caused the condition.Ĭlinical examination involving palpation (touching) of the bone to establish any point tenderness called and ‘N spot’. Pain usually eases quickly when not bearing weight through the foot. Pain may be on the inner arch of your foot. SIGNS & SYMPTOMS Possible slow onset of pain in the middle of your foot, but due to the traumatic tendency of this injury, the pain could be sudden. Because the middle third of this bone has a poor blood supply, fractures may not heal properly and so pain may persist when weight bearing. It is thought that a mixture of high load bearing and this muscle contraction can lead to progressive bone damage and ultimately a stress fracture. When this contracts it places a stress upon the bone. ![]() One of the muscles (tibialis posterior) in your calf attaches to the bone. The exact mechanism for this fracture remains under investigation, but the injury is common. When high forces are placed through it, it is possible to get a crack in it.Īny activity that sees the foot exposed to huge landing forces (sprinting, hurdling, games on hard ground), can expose you to this type of injury. GENERAL INFORMATION The navicular is a large bone in the middle of your foot and is among the most common reasons (in sport) causes of pain in this region. ![]()
