Clinical outcomes of buttress plating in treating posterior Pilon fractures through modified posteromedial approach / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To explore clinical outcomes of buttress plating in treating posterior Pilon fracture by amodified posteromedial approach.</p><p><b>METHODS</b>From July 2014 to January 2015, 10 patients with posterior Pilon fracture were respectively analyzed, including 7 females and 3 males, aged from 31 to 54 years old. One patient were type , 3 patients were type IIand 6 patients were type III according to classification of Pilon fracture by YU Guang-rong. All patients were treated by buttress plating through amodified posteromedial approach. Postoperative complications, fracture healing and reduction were observed, AOFAS score were used to evaluate function recovery at 1 year after operation.</p><p><b>RESULTS</b>All patients were followed up for 12 to 18 months with an average of(14.1±3.2) months. All incisions were primarily healed at stage I without wound complication, neurovascular injuries or musculus flexor contracture. According to Burwell-Charnley imaging scoring, 8 patients got anatomical reduction and 2 patients got moderate reduction. All fracture got healing from 12 to 16 weeks with an average of(13.2±1.8) weeks. According to AOFAS score at 1 year after operation, 8 got excellent results and 2 moderate. All patients returned to work at about(4.7±1.4) months (ranged from 3 to 6 months) after operation.</p><p><b>CONCLUSIONS</b>Buttress plating using a modified posteromedial approach in treating posterior Pilon fractures is an effective method, has less complications, and could recovery early weight-bearing functional exercise.</p>
