Introduction/Purpose:
Proximal fifth metatarsal fractures are a common foot injury. Previous surgical treatments have consisted of intramedullary screw fixation and a newer technique of plantar plating due to non-union and refractures seen with screw fixation. Purpose of this multi-surgeon case series study is to evaluate clinical and radiographic outcomes and complication rates after fifth metatarsal plating for proximal fifth metatarsal fractures in recreational and elite athletes.
Methods:
Retrospective multiple surgeon case series involving patients who underwent fifth metatarsal plantar plating for proximal fifth metatarsal fractures with a mean follow-up of 33.1 months (range, 12-52). Elite and recreational athletes were included. Demographic data, radiographic evaluation, and clinical notes were analyzed. Patient phone conversations were made to document complications outside of our electronic medical record.
Results:
Forty-four patients (45 fractures) were treated with plantar plating technique with a mean age of 37.3 years (range 14- 80). Five patients sustained refractures (11.1% of patients), 2 at previous fracture site, 1 through a screw hole, 1 proximal to plate, and 1 distal to plate. All refractures were treated non-operatively. No wound complications were seen. No secondary revision surgery was needed and union rate was 100% at final follow up.
Conclusion:
With a one year minimum follow up, plantar plating of proximal fifth metatarsal fractures is a viable option for treatment of both acute and chronic fractures as well as after failed intramedullary screw fixation with low refracture rates and without non-unions. Plantar plating allows the surgeon to have direct visualization of fracture reduction and ease of access for bone grafting. Both elite and recreational athletes can benefit from the plating technique.
