Clinical outcome of modified posterolateral approaches for the treatment of posterolateral tibial plateau fractures / 中国综合临床

ABSTRACT

Objective To observe the clinical outcome of modified posterolateral approaches for the treatment of posterolateral tibial plateau fractures. Methods From January 2012 to January 2015,13 patients with posterolateral tibial plateau fractures were identified in the Second Hospital of Changzhou Affiliated to Nan?jing Medical University. All the posterolateral fractures were fixated with a plate. The knee function was evaluated at the last follow?up by the Hospital for Special Surgery( HSS) Score,and the occurrence of postoperative compli?cations were observed. Results Thirteen patients were followed up for an average of 14. 4 months,all patients obtained bony union. There were no significant differences regarding the mean HSS score among 3 months, 6 months and 1 year post?operation((71. 6±1. 5) points, (76. 4±1. 6) points, (83. 2±1. 1) points;P=0. 154) . There were no significant differences regarding the tibial plateau angle and posterior slope angle on radiograph?ies of inside and outsideamong immediate,6 and 12 months postoperation((83. 7±1. 7)°,(84. 3±1. 5)°,(85. 1 ±1. 4)°,(85. 4±1. 5)°;(7. 7±1. 5)°,(7. 7±1. 4)°,(7. 7±1. 3)°,(7. 6±1. 8)°;P=0. 223,0. 191). No com?plications associated with the approach were observed and there was no infection,no malunion or fixation failure either. Conclusion In the treatment of posterolateral tibial plateau fractures,the modified posterolateral approa?ches can result in excellent fracture reduction under direct visualization and allow for posterior buttress plating.
