The actual rate of occurrence is unknown but some estimate the rate at somewhere between 0.7 and 1.9 percent of all foot fractures. Together, the metatarsal and tarsal bones help to form the main arches of the foot, which are essential for weight-bearing and walking. paracetamol and ibuprofen) as needed Elevate your leg while sitting by using pillows or a stool - this will. You might develop it if you participate in activities that involve running and jumping. What should I do Take regular pain relief (e.g. 5. Podiatric physicians commonly see fifth metatarsal fractures when treating active patients. Metatarsalgia (met-uh-tahr-SAL-juh) is a condition in which the ball of your foot becomes painful and inflamed. Background: Metatarsal fractures are among the most common foot and ankle injuries, with an annual incidence of 6.7 per 100 000 persons.2.2 Jones or metaphyseal-diaphyseal junction fracture.2.1 Dancer, pseudo-Jones, or tuberosity (styloid) avulsion fracture. The fifth metatarsal bone starts to protrude outward, while the little toe moves. They can also be caused by repetitive twisting. The fifth metatarsal is a long bone in the foot that sits behind the fifth Toe. In this report, a case of recurrent fifth metatarsal stress fractures in a professional soccer player with hypoparathyroidism is presented. 6.7 per 100 000 persons ( 1 ), with the base of the fifth metatarsal bone (MT5) being most commonly involved. 1 Citations Metrics Abstract Background Hypoparathyroidism is characterized by low or inappropriately normal levels of parathyroid hormone leading to hypocalcemia. A vascular watershed area exists in zone 2, contributing to the high nonunion rates seen with these fractures.Ĭopyright © 2023, StatPearls Publishing LLC. Fractures to the fifth metatarsal occur with direct trauma to the foot, such as crushing in a football tackle. Metatarsal fractures are among the most common foot injuries, with an incidence of approx. What is a fifth metatarsal fracture At OrthoArizona, metatarsal fractures are some of the most common fractures we see. Metaphyseal arteries and diaphyseal nutrient arteries provide the blood supply to the fifth metatarsal base. Additionally, a patient may sustain a shaft fracture greater than 1.5 cm distal to the tuberosity, a long spiral fracture extending into the distal metaphyseal area, the so-called dancer's fracture, or a stress fracture of the metatarsal.Ĭlassification of these fractures is crucial to making management decisions. Fractures of the 5th metatarsal are fairly common and can. If a fracture is identified in a single metatarsal, the orthopedist must closely inspect adjacent metatarsals and joints, especially the Lisfranc articulation. The fifth metatarsal is the long bone on the outside of the foot that connects to the small toe. Fractures through zone 1 are called pseudo-Jones fractures, and fractures through zone 2 are referred to as Jones fractures. Although most first and fifth metatarsal fractures are isolated fractures, multiple metatarsal fractures often occur in contiguous bones. Fractures (breaks) are common in the fifth metatarsal the long bone on the outside of the foot that connects to the little toe. Nevertheless, it is critical that the clinician recognizes all injury patterns of the fifth metatarsal and initiate the appropriate treatment plan or referral process to avoid potential complications.Ĭlassified by Lawrence and Bottle, the base, or proximal aspect, of the fifth metatarsal is broken up into three anatomical zones: zone 1, the tuberosity zone 2, the metaphyseal-diaphyseal junction and zone 3, the diaphyseal area within 1.5 cm of the tuberosity. Since orthopedic surgeon Sir Robert Jones first described these fractures in 1902, there has been an abundance of literature focused on the proximal aspect of the fifth metacarpal due to its tendency towards poor bone healing. Fractures of the fifth metatarsal are common injuries that must be recognized and treated appropriately to avoid poor clinical outcomes for the patient.
