Abstract

PURPOSE
To evaluate the clinical and radiological results of internal fixation with tension band wiring for the fracture at the base of fifth metatarsal bone.
MATERIALS AND METHODS
From January 2008 to December 2009, 15 cases with displaced fracture at the base of fifth metatarsal were analyzed and average follow up period was 13.8 months. Lawrence classification was used to classify fracture type. We evaluated clinical results by American Orthopedic Foot Ankle Society (AOFAS) midfoot score and radiological results by union time. Complications was also checked.
RESULTS
According to classification, zone I fracture were 11 cases and zone II fracture were 4 cases. Bony union was achieved in all cases after 7 weeks. In the final follow-up, average AOFAS score was 94. There were no complications except hardware irritation.
CONCLUSION
Satisfactory results were obtained after tension band wiring for the fifth Metatarsal base fracture in zone I fracture or comminuted zone II fracture for which it is not easy to be fixed with screw.
