At what age does the 5th metatarsal apophysis fuse?
Apophysis of the fifth metatarsal base appears on radiographs at age 10 for girls, and age 12 for boys. Fusion of the apophysis and the fifth metatarsal base usually takes place within the following 2–4 years.
Is there a growth plate on 5th metatarsal?
Iselin disease is painful irritation and inflammation of the apophysis (growth plate) at the base of the 5th metatarsal (foot bone), where one of the calf muscles inserts. In a child, the bones grow from areas called growth plates.
Which muscle attaches to the base of the 5th metatarsal?
peroneus brevis muscle
The tuberosity of fifth metatarsal bone [V] is a rough eminence, on the lateral side of the base of fifth metatarsal bone for the attachment of the peroneus brevis muscle.
What is apophysis of 5th metatarsal?
The apophysis of the proximal 5th metatarsal (plural apophyses) lies laterally and is oriented longitudinally parallel to the shaft. Apophysis of the fifth metatarsal base appears on plain radiographs at age 12 for boys and 10 for girls.
What is the difference between apophysis and epiphysis?
The epiphysis is a rounded end of long bone that has direct articulation with bone at the joint. An apophysis is a normal developmental outgrowth of a bone, which arises from a separate ossification center, and fuses to the mother bone later in development.
How long does 5th metatarsal take to heal?
How long will it take to heal? Most fractures heal without any problems in about six weeks. However, it may take three to six months for your symptoms to settle completely – these can include pain or discomfort, stiffness, decreased strength, and swelling.

What type of bone is the 5th metatarsal?
(Left.) As with the four other metatarsal bones it can be divided into three parts; a base, body and head. The base is the part closest to the ankle and the head is closest to the toes….Muscle attachments.

Where is the base of the 5th metatarsal?
The base of the fifth metatarsal is located on the outside (lateral) aspect of the foot where you can feel a prominent bone, about half way along the length of the foot. There are two types of 5th Metatarsal base fractures: Avulsion Fractures (Dancer’s Fractures) Stress Fractures (Jones’ Fractures)
When does apophysis of the fifth metatarsal base occur?
Apophysis of the fifth metatarsal base appears on plain radiographs at age 12 for boys and 10 for girls. Fusion of the apophysis to the metatarsal base usually occurs within the following 2-4 years 3,4. It should not be confused with an os peroneum or an avulsion fracture.
When does the 5th metatarsal fuse in girls?
The 5th metatarsal generally fuses completely by around 14 for young boys and 11 to 12 years of age for young girls. The benefit of this and the reason the condition is considered benign is that the pain generally resolves as the growth plate fuses and hardens into bone.
Where is the growth plate in the foot?
Iselin disease is painful irritation and inflammation of the apophysis (growth plate) at the base of the 5th metatarsal (foot bone), where one of the calf muscles inserts. In a child, the bones grow from areas called growth plates. The growth plate is made up of cartilage, which is softer and more vulnerable to injury than mature bone.
What causes a metatarsal fracture in a child?
