摘要
目的比较长节段和短节段椎弓根系统治疗青壮年胸腰椎骨折的效果。观察常用的脊柱骨折分型对短节段固定预后的影响。方法对72例胸腰椎骨折的青壮年患者随机采用后路短节段和长节段固定手术,随访观察有无内固定失败,X线检查测量12个月后的后凸矫形丢失度。短节段固定按脊柱AO分型和载荷-分享分型不同分组后,比较各组结果差异。患者术后均不予外固定。结果随访平均矫形丢失度,长节段组为6.1°,短节段组为7.3°,差异无统计学意义(P>0.05)。短节段固定中,不同脊柱AO分型(A、B、C)和载荷-分享分型(≤6、≥7)组别的矫形丢失度差异均无统计学意义(P>0.05)。结论随着器械和手术技术的进步,青壮年患者胸腰段骨折,即便是严重不稳定骨折,采用短节段椎弓根系统固定可取得较好效果,患者术后也无需外固定。
Objective To compare the effect of short-segment and long-segment pedicle instrumentation in treatment of thoracolumbar fractures of youngsters and determine whether common classification systems can predict the radiologic outcome of short-segment fixation. Methods A retrospective radiographic review was conducted for 72 thoracolumbar fractures of youngsters treated with long-segment （35 patients, group L） and short-segment （37 patients, group S） posterior instrumentation to determine the rate of correction loss （12 months later） and instrumentation failure. The outcome of group S in relation to the load sharing classification of spine fracture system and the AO classification of fractures system were compared. No postoperative bracing was used.Results No failures occurred in both groups. An average loss of correction of 6.1 degree （group L） and 7.3 degree （group S） were observed. No relationship was shown between loss of correction and load sharing classification （≤6 or ≥17 points）, loss of correction and AO classification.Conclusion With modem instrumentation and techniques, short-segment thoracolumbar fracture fixation could be used successfully in youngsters despite highly comminuted injuries, without supplemental bracing.
