What is a Base of 5th Metatarsal Fracture?
Description:
A base of the 5th metatarsal fracture is a common foot injury characterized by a break at the base of the fifth metatarsal bone, which is located on the outer side of the foot. This type of fracture can vary in severity and often occurs due to trauma or overuse. To effectively manage base of 5th metatarsal fractures, it's essential to understand their anatomy and how they develop.
Anatomy of the 5th Metatarsal:
The fifth metatarsal is a long bone that runs along the outer edge of the foot, connecting to the pinky toe. The base of the fifth metatarsal, the widest part of the bone, is located closest to the ankle.
Development of Base of 5th Metatarsal Fractures:
Base of 5th metatarsal fractures can occur due to:
Trauma: Sudden injuries, such as rolling the ankle or direct impact to the foot, can cause fractures at the base of the fifth metatarsal.
Overuse or Stress: Repetitive activities, such as running or jumping, can lead to stress fractures in this area, particularly in athletes.
Common Types of Base of 5th Metatarsal Fractures:
Avulsion Fracture: A small piece of bone is pulled away by the attached tendon or ligament.
Jones Fracture: A transverse fracture that occurs at the junction between the base and the shaft of the fifth metatarsal.
Stress Fracture: Tiny cracks in the bone resulting from repetitive stress and overuse.
Signs and Symptoms:
Common signs and symptoms of base of 5th metatarsal fractures include:
Pain: Pain, often sharp and localized, at the outer edge of the foot.
Swelling: Swelling may occur around the fracture site.
Bruising: Bruising can develop due to blood vessel damage at the fracture site.
Difficulty Walking: Pain and instability can make walking challenging.
