| Popis: | There is still much controversy regarding the management of proximal fifth metatarsal fractures more than a century after its original description by Sir Robert Johns1) in 1902, as even today there are no specific guidelines for the management of these fractures. Many classifications have been described for proximal fifth metatarsal fractures.2-6) However, we prefer the three zone concept by Lawrence and Botte3) when classifying these fractures (Fig. 1). Zone I is the most proximal tuberosity avulsion fracture. Zone II is the metaphyseal-diaphyseal junction, and it is also the level of the fourth and fifth metatarsal articulations. This is the true Jones fracture location. Zone III is site of proximal diaphyseal stress fracture. Zone I and zone II fractures are due to acute injury, whereas the zone III fractures are usually pathological stress fractures. Fig. 1 Schematic representation of the fracture zones for fifth metatarsal base fractures by Lawrence and Botte3) (zone I, zone II, zone III) and the gray-colored area represents the zone II and intraarticular zone I fractures for surgical intervention in this ... It is of utmost importance to distinguish between the acute fractures and the diaphyseal stress fractures for proper management.7) Undisplaced zone I and zone II fractures usually respond well to conservative treatment; however, operative fixation of the displaced zone II fractures and the displaced intraarticular zone I fractures has shown better results than conservative treatment.6,8-10) To date, no clinical study has evaluated the effectiveness of percutaneous bicortical screw fixation for these fractures. Therefore, the aim of this study was to evaluate the effectiveness of percutaneous bicortical screw fixation for the displaced intraarticular zone I and zone II fractures of the proximal fifth metatarsal. We also evaluated the short- and long-term clinical and radiological results of the bicortical fixation of these fractures. |
