ConclusionĮarly diagnosis and appropriate treatment can obtain good therapeutic results in fifth MBF patients combined with LCAL injury. None of the patients had complications such as delayed union, nonunion, and incision infection. For fifth MBF with displaced more than 2 mm, hook plate or lag screw was used for fixation for complete rupture of LCAL, suture anchor was used to repairing the ligament for partial LCAL injury, plaster was used for fixation after surgery for avulsion fractures, cannulated screw or suture anchor was used for repair. The average fracture healing time was 8.3 (range, 6–12) weeks. The incidence of fifth MBF with LCAL injury accounted for 63.93% of fifth metatarsal base fracture the most common causes of injury included sprains and falls. There was no significant difference between the patients without LCAL injury and the patients with LCAL injury in terms of age ( p = 0.67) and gender ( p = 0.575). Among the 39 patients with LCAL injury, 24 patients with Grade I–II injury, 6 patients with Grade III injury, and 9 patients with avulsion fractures. In 61 patients, there were 39 patients with LCAL injury. The type of surgery varied base on the individual patients (type of fracture with/without lateral collateral ankle ligament injury). After admission, patients were given the symptomatic treatment and underwent standard anteroposterior (AP), 30-degree oblique foot radiographs, ankle MR and/or ultrasonic examination. We retrospectively analyzed 61 patients with fifth MBF. ![]() However, there is no relevant report on the incidence, injury type and treatment principle of the fifth MBF combined with an LCAL injury. The foot and ankle surgeon will determine the type of procedure that is best suited to the individual patient.Ĭopyright © 2012 | American College of Foot and Ankle Surgeons (ACFAS), All Rights Reserved.Fifth metatarsal base fracture (fifth MBF) and lateral collateral ankle ligament (LCAL) injury are mainly caused by plantar flexion and inversion of the foot. If the injury involves a displaced bone, multiple breaks, or has failed to adequately heal, surgery may be required. Bone stimulation, most commonly used for Jones fractures, may be used as part of the treatment or following an inadequate response to immobilization. A pain-free external device is used to speed the healing of some fractures. Crutches may also be needed to avoid placing weight on the injured foot. Depending on the severity of the injury, the foot is kept immobile with a cast, cast boot, or stiff-soled shoe. The foot and ankle surgeon may use one of these non-surgical options for treatment of a fifth metatarsal fracture: Elevation: The foot should be raised slightly above the level of your heart to reduce swelling.Compression: An elastic wrap should be used to control swelling.Use ice for 20 minutes and then wait at least 40 minutes before icing again. Ice: Apply an ice pack to the injured area, placing a thin towel between the ice and the skin.Until you are able to see a foot and ankle surgeon, the “ R.I.C.E.” method of care should be performed: Because a Jones fracture sometimes does not show up on initial x-rays, additional imaging studies may be needed. ![]() The foot will be examined, with the doctor gently pressing on different areas of the foot to determine where there is pain. To arrive at a diagnosis, the surgeon will ask how the injury occurred or when the pain started. Pain, swelling, and tenderness on the outside of the footĪnyone who has symptoms of a fifth metatarsal fracture should see a foot and ankle surgeon as soon as possible for proper diagnosis and treatment.Examples include mid-shaft fractures, which usually result from trauma or twisting, and fractures of the metatarsal head and neck.Īvulsion and Jones fractures have the same signs and symptoms. Other types of fractures can occur in the fifth metatarsal. They are less common and more difficult to treat than avulsion fractures. Jones fractures are caused by overuse, repetitive stress, or trauma. A Jones fracture can be either a stress fracture (a tiny hairline break that occurs over time) or an acute (sudden) break. Jones fractures occur in a small area of the fifth metatarsal that receives less blood and is therefore more prone to difficulties in healing. Avulsion fractures are often overlooked when they occur with an ankle sprain. This type of fracture is the result of an injury in which the ankle rolls. In an avulsion fracture, a small piece of bone is pulled off the main portion of the bone by a tendon or ligament. Two types of fractures that often occur in the fifth metatarsal are: Fractures (breaks) are common in the fifth metatarsal – the long bone on the outside of the foot that connects to the little toe. ![]()
