5th metatarsal fracture foot12/9/2023 Removable walking cast – weight bearing allowed.Please click here to read the Foot and Ankle Surgery Department’s comprehensive patient resource on foot and ankle fractures and their treatment. Some medications (such as prednisone and anti-inflammatory medications).Excess weight bearing (when weight bearing is allowed).Premature weight bearing (when non-weight bearing has been recommended).It is possible for these factors to severely slow the bone healing process or even result in non-healing of your fracture: Change in shoe size or inability to wear desired footwearĪlso, keep in mind that there are a number of factors that can impair bone healing.Transfer of pain, fracture, or callus to new site.Failure or breakage of hardware or implanted materials.Intolerance of hardware or implanted materials.Wound or scar problems (poor or slow healing, thick scar, sensitive scar, unsightly scar).Circulation disturbance of soft tissues or bone (including avascular necrosis of bone).Tendon injury or disruption of tendon function.Complex regional pain syndrome (CRPS or RSD).Growth disturbance (particularly with growth center injuries).Malalignment and deformity (malunion of bone).Failure of bone healing (delayed or non-healing of bone).General complications of foot and ankle fractures may include: Tips and Instructions from the Cast RoomĪlthough 5th metatarsal fractures are typically successfully managed with non-surgical care, there are some potential risks of the fracture and the management of the fracture.Ankle Fracture with Unstable Syndesmosis.Patients with Sensation or Circulation Loss in the Feet.Midfoot Impingement Syndrome and Degenerative Joint Disease of the Midfoot.Excess Body Weight and Foot and Ankle Problems.Fifth Metatarsal Fractures and Current Treatment. Zone II and III Fifth Metatarsal Fractures in Athletes. A Look Back in Time: Sir Robert Jones, 'Father of Modern Orthopaedics'. Fractures of Proximal Portion of Fifth Metatarsal Bone: Anatomic and Imaging Evidence of a Pathogenesis of Avulsion of the Plantar Aponeurosis and the Short Peroneal Muscle Tendon. Theodorou D, Theodorou S, Kakitsubata Y, Botte M, Resnick D. Fracture of the Base of the Fifth Metatarsal Bone by Indirect Violence. Avulsion Fracture of the Base of the Fifth Metatarsal Not Seen on Conventional Radiography of the Foot: The Need for an Additional Projection. Distinguishing Jones and Proximal Diaphyseal Fractures of the Fifth Metatarsal. Chuckpaiwong B, Queen R, Easley M, Nunley J. Internal fixation and even bone grafting may be required in cases of non-union, or where the fracture is significantly displaced. The outcomes are similar with almost 100% union rates 7. Management includes either intramedullary screw fixation or open reduction and internal fixation (ORIF is also the main management option as a salvage procedure when there is non-union following screw fixation) 7. Operative management is indicated in patients that are elite or competitive athletes or in non-operatively managed fractures when delayed union has occurred 7,8. Relative to avulsion fractures, Jones fractures are particularly prone to non-union (with rates as high as 30-50%) due to being in a vascular watershed zone, and almost always take longer than two months to heal 2.ĭisplacement of the fracture can increase with persistent weight-bearing, therefore, immobilization is important as part of the initial therapy, with a non-weight bearing cast for 6-8 weeks. Indications for non-operative management include undisplaced fractures and fractures in patients with limited activity (i.e. ![]() Jones fracture is located at the metadiaphyseal junction, approximately 2 cm (1.5-3 cm) from the tip of the 5 th metatarsal, and has a predominantly horizontal course. Radiographic features Plain radiograph/CT The fracture is believed to occur as a result of significant adduction force to the forefoot with the ankle in plantar flexion 5. It is a transverse fracture at the base of the fifth metatarsal, 1.5 to 3 cm distal to the proximal tuberosity at the metadiaphyseal junction, without distal extension.
