摘要:

背景:Schazker Ⅴ、Ⅵ型骨折常造成交叉韧带、侧副韧带及半月板等部位的损伤,且塌陷移位严重,若仅采用一侧锁定钢板,则较难支撑及满意复位。
目的:比较双切口双钢板内固定与膝前正中切口锁定钢板内固定修复Schatzker Ⅴ、Ⅵ型胫骨平台骨折后的效果及稳定性评价。
方法:纳入76例Schazker Ⅴ、Ⅵ型胫骨平台骨折患者,分别采用锁定钢板内固定(n=38)和双切口双钢板内固定(n=38)进行治疗,通过X射线正、侧位片评估骨折复位及愈合情况,并对胫骨平台内翻角、胫骨平台内侧后倾角进行生物力学测试。
结果与结论:双切口双钢板内固定组住院时间、内固定后开始负重时间显著少于锁定钢板内固定组(P < 0.05),但两组骨折愈合时间比较差异无显著性意义(P > 0.05);关节强直、骨折延迟愈合、针道感染、骨折延迟愈合、膝内翻畸形多项并发症比较,双切口双钢板内固定组显著少于锁定钢板内固定组,差异均有显著性意义(P < 0.05)。两组内固定松动断裂、膝关节不稳、切口感染、皮肤坏死、骨坏死及骨不愈合多项并发症比较,差异无显著性意义(P > 0.05);双切口双钢板内固定组内固定后Rasmussen分级明显优于锁定钢板内固定组,差异均有显著性意义(P < 0.05)。结果说明治疗Schatzker Ⅴ、Ⅵ型胫骨平台骨折,双切口双钢板内固定的临床疗效优于膝前正中切口锁定钢板内固定,更具有生物力学上的稳定性。

Abstract:

BACKGROUND: Schatzker V, VI fracture often causes the injuries to cruciate ligament, collateral ligaments and meniscus. Moreover, the collapse and shifting were severe. The locking plate on one side cannot support the weight or obtain satisfactory reduction.
OBJECTIVE: To compare the effects and stability of the dual-incision double-plate fixation and knee midline incision locking plate fixation in the treatment of Schatzker V, VI tibial plateau fracture.
METHODS: A total of 76 patients with Schatzker V, VI tibial plateau fracture were respectively treated with locking plate fixation (n=38) and dual-incision double-plate fixation (n=38). Fracture reduction and healing were assessed using anteroposterior and lateral radiographs. Varus angle and medial caster angle of tibial plateau received biomechanical measurement.
RESULTS AND CONCLUSION: Hospital stay and postoperative load time were significantly less in the dual-incision double-plate fixation group than in the locking plate fixation group (P < 0.05). No significant difference in healing time was detected between locking plate fixation and dual-incision double-plate fixation groups (P > 0.05). The number of complications, such as ankylosis, fracture delayed union, pin tract infection,  
delayed union, varus deformity, was significantly fewer in the dual-incision double-plate fixation group than in the locking plate fixation group (P < 0.05). There were no significant differences in the fracture of loosening, knee instability, wound infection, skin necrosis, bone necrosis and nonunion between the dual-incision double-plate fixation and locking plate fixation groups (P > 0.05). Postoperative Rasmussen classification was significantly better in the dual-incision double-plate fixation group than in the locking plate fixation group (P < 0.05). Experimental results indicated that the clinical efficacy of the dual-incision double-plate fixation is superior to that of the anterior cruciate midline incision locking plate fixation in the treatment of Schatzker V, VI type tibial plateau fractures. The dual-incision double-plate fixation has more biomechanical stability.
