文题释义:
阻挡螺钉技术:是指垂直于交锁钉平面紧靠髓内钉旋入一二枚螺钉,使髓腔变窄,复位时能引导髓内钉沿着正确的方向插入远端的中心位置,术后阻挡螺钉能阻挡髓内钉摆动,起到3点固定的力学作用,增强髓内钉固定的稳定性。
阻挡螺钉与普通锁钉的区别:①阻挡螺钉能矫正对线,控制髓内钉插入方向,而普通锁钉没有这一作用;②标准的普通锁钉在静力模式下只能控制旋转和肢体的长度,而阻挡螺钉能控制成角和侧方移位;③在干骺端斜行骨折阻挡钉可使剪力变成压缩力,增加稳定性;④阻挡螺钉只用于干骺端骨折和髓内钉与髓腔不匹配的情况,而标准的普通锁钉任何情况下都可以使用。
 
摘要
背景:对于胫骨远段骨折,采用切开复位钢板内固定、经皮微创钢板固定及髓内钉固定均是有效修复方法,但各有优缺点。
目的:比较髓内钉结合阻挡螺钉技术与经皮微创钢板固定置入治疗胫骨远段骨折的疗效。
方法:纳入51例胫骨远段骨折患者,按治疗方法分为2组,阻挡螺钉组(n=23)应用交锁髓内钉闭合穿钉结合阻挡螺钉置入固定,钢板固定组(n=28)采用经皮微创钢板固定。随访观察骨折愈合时间、胫骨功能恢复及并发症发生情况。
结果与结论:随访8-32个月:①除钢板固定组1例骨不连外,其余患者均获得骨性愈合,阻挡螺钉组愈合时间为(4.6±1.7)个月,钢板固定组愈合时间为(6.9±2.3)个月,两组间愈合时间比较差异有显著性意义(P < 0.05);②阻挡螺钉组胫骨功能恢复优良率为100%,显著高于钢板固定组的82%(P < 0.05);③阻挡螺钉组、钢板固定组的不良事件发生率分别为13%、18%,组间比较差异无显著性意义(P > 0.05);④结果表明,交锁髓内钉结合阻挡螺钉置入内固定修复胫骨远段骨折,可促进骨折愈合与关节功能恢复。

Abstract:

BACKGROUND: For the treatment of distal tibial fractures, open reduction and plate fixation, minimally invasive percutaneous plate fixation and intramedullary nail fixation are effective, but each has advantages and disadvantages.

OBJECTIVE: To compare the effects of intramedullary nail combined with blocking screws versus minimally invasive percutaneous plate fixation in treating distal tibial fractures.
METHODS: Fifty-one cases of distal tibial fractures were divided into two groups. The blocking screw group (23 cases) was treated with closed reduction and internal fixation with interlocking nail combined with blocking screws. The plate fixation group (28 cases) was treated with minimally invasive percutaneous plate fixation. Fracture healing time, recovery of tibial function and complication occurrence were observed during follow-up.
RESULTS AND CONCLUSION: All patients were followed up for 8 to 32 months. (1) Except one patient in the plate fixation group, the other patients had bony union. The healing time was (4.6±1.7) months in the blocking screw group and (6.9±2.3) months in the plate fixation group. Significant differences in healing time were detected between the two groups (P < 0.05). (2) The excellent and good rate of tibial function recovery was significantly higher in the blocking screw group (100%) than in the plate fixation group (82%) (P < 0.05). (3) No significant difference in the incidence of adverse events was determined between the blocking screw group (13%) and plate fixation group (18%) (P > 0.05). (4) Results suggested that interlocking intramedullary nail combined with blocking screw fixation in the treatment of distal tibial fractures can promote fracture healing and joint function recovery.
