Abstract:
Objective To compare the therapeutic effects of locking compression plate distal ulna hook plate (LCP-DUHP) and cannulated screws in the internal fixation for fractures of the fifth metatarsal base at zones Ⅰ and Ⅱ.Methods This retrospective study included 67 patients who had been treated for fractures of the fifth metatarsal base at zones Ⅰ and Ⅱ from July 2013 through December 2015.Of them,29 were treated by internal fixation with cannulated screws,including 17 men and 12 women with an average age of 46.6 years.There were 13 zone Ⅰ fractures and 16 zone Ⅱ fractures according to the Lawrence-Botte partition.The other 38 patients were treated by internal fixation with LCP-DUHP,including 20 men and 18 women with an average age of 33.7 years.There were 20 zone Ⅰ fractures and 18 zone Ⅱ fractures according to the Lawrence-Botte partition.The therapeutic effects were evaluated at the final follow-ups using visual analogue scale (VAS) for the affected feet,American Orthopaedic Foot and Ankle Society (AOFAS) midfoot scoring system,and incidence of postoperative complications.Results All this series were followed up for 51 to 87 weeks (average,57weeks).There were no significant differences between the cannulated screws group and the LCP-DUHP group in terms of fracture healing time (13.9 ± 1.6 weeks versus 14.2 ± 1.8 weeks),VAS scores (4.9 ± 1.3 versus 4.8 ± 1.O) or AOFAS midfoot scores (87.9 ± 3.4 versus 88.6 ± 2.5) (P ＞ 0.05).Bony union was achieved in all.No implant failure was observed in this series.Conclusion Both LCP-DUHP and cannulated screws can lead to satisfactory therapeutic effects in the treatment of fractures of the fifth metatarsal base at zones Ⅰ and Ⅱ.
