Treatment of Fifth Metatarsal Zone 3 Fractures

Not Applicable

Recruiting

• Conditions: Metatarsal Fracture; Fractures, Stress

• Registration Number: NCT04847115
• Lead Sponsor: Ostfold Hospital Trust

Brief Summary

The fifth metatarsal is one of the bones where stress fractures can occur. Current literature provides support for both operative and non-operative treatment, but is mostly based on retrospective studies. One small randomized controlled trial reported faster recovery in the surgery group, but this study is probably subject to selection bias as well as underpowered design. There is a need to strengthen the knowledge base regarding treatment of stress fractures in the fifth metatarsal. This study seeks to answer whether osteosynthesis with an intramedullar screw fixation gives faster painfree weight bearing compared to non-operative treatment with a walking boot.
