Abstract

Background This study assessed the clinical and radiological outcomes of different non-surgical interventions, surgical versus non-surgical interventions, and different surgical interventions used in the management of proximal fifth metatarsal fractures. Methods A systematic review of published and unpublished literature was undertaken. Results Six studies, assessing 330 patients and 333 fractures of the proximal fifth metatarsal were reviewed. Four studies assessed outcomes following tuberosity fractures, whilst 2 studies recruited patients following proximal diaphyseal or Jones fractures. The findings suggested that bandage is superior to below knee cast immobilisation for patient-reported functional and pain scores, with no difference in fracture union or re-fracture, and a shorter duration to return to work. There was no significant difference in complication rates or functional outcomes for patients managed in a plaster slipper compared to a bandage post-injury. When comparing surgical and non-surgical management, intramedullary screw fixation results in a shorter time to fracture union, reduced complication rates and earlier return to pre-injury activities compared to non-surgical cast immobilisation. However, the evidence-base is limited in it size and presented with a number of methodological limitations. Conclusions Further well-conducted randomised controlled trials are required to determine the optimal management strategy for the different types of proximal fifth metatarsal fractures.
