A nondisplaced avulsion fracture of the tuberosity of the unspecified calcaneus is a type of foot injury that can occur as a result of sudden and forceful pulling of the Achilles tendon. This type of injury is commonly seen in athletes who engage in sports that require a lot of jumping or running, such as basketball or soccer.
When an avulsion fracture occurs, a small piece of bone is pulled away from the main bone due to the pulling force of the tendon. In a nondisplaced fracture, the bone fragments remain in their original position and do not shift out of place.
Symptoms of a nondisplaced avulsion fracture of the tuberosity of the unspecified calcaneus include pain, swelling, and tenderness in the affected area. There may also be difficulty walking or bearing weight on the injured foot.
In some cases, a cast or brace may be necessary to immobilize the foot and allow the fracture to heal. Physical therapy may also be recommended to help restore strength and flexibility to the affected foot.
Overall, a nondisplaced avulsion fracture of the tuberosity of the unspecified calcaneus can be a painful and debilitating injury. However, with proper treatment and care, most people are able to make a full recovery and return to their normal activities.
