This usually occurs from an injury where the foot and ankle are twisted downward and. Unfortunately, the terminology and descriptions of these injuries remain confusing in the orthopedic literature. Most commonly, the fifth metatarsal fractures through the base of the bone. There are 3 distinct fracture patterns that affect the base of the fifth metatarsal. Injuries to this bone may act differently than fractures of the other four metatarsals. In adults, high forces are required to fracture the first metatarsal. The fifth metatarsal is the long bone on the outside of your foot. Direct blows and twisting injuries cause many of these fractures. in children it should be differentiated from the apophysis of the fifth metatarsal base of the fifth metatarsal fracture os peroneum. It is situated at the base of the fifth metatarsal in the peroneus brevis tendon 1. Approximately one-third of metatarsal fractures involve the shaft or distal portion of the metatarsal. It is formed as a result of failed fusion of the secondary ossification centre of the metatarsal. Functional weight-bearing such as Robert Jones bandage or elastic bandaging and stiff-soled shoes has better outcomes than non-weight-bearing in a short leg cast 5.įor large or very displaced fragments with intra-articular extension then operative fixation may be indicated. Excluding toe fractures, metatarsal fractures are the most common foot fracture 1-4. The most frequent fracture seen is the fifth metatarsal, accounting for 68 of. In general, these fractures can be treated conservatively, and heal well 2. In adults, metatarsal fractures peak in the second to fifth decades of life. An avulsion fracture of the fifth metatarsal occurs where a tendon attaches to the bone at. The fifth metatarsal is the bone that runs from the midfoot to the base of the small toe on the outside of the foot. In some instances, the fracture may be occult. An avulsion fracture of the fifth metatarsal, also called a 'pseudo-Jones fracture,' is the most common type of fifth metatarsal fracture. Injuries to the metatarsal bones are very common and can happen in a number of ways, but most commonly occur when a heavy object falls on them or when they are twisted during a fall. Treatment of a metatarsal fracture depends heavily on which bone is fractured. It usually does not reach the tarsometatarsal (metatarsocuboid) joint, but occasionally does. Each metatarsal is broken down into segments: the head, neck, shaft, and base. Small fracture usually of the tuberosity of the proximal 5 th metatarsal, oriented mostly transversely (cf.
