 文题释义:
骨质疏松性骨折:人体的骨组织处于动态变化中,身体会不停制造新的骨组织,而旧的骨组织会被分解及取代。通常在35岁前后,人体骨量达到峰值。此后随着年龄的增长,骨量开始流失且不可逆转。患骨质疏松症后,患者因骨密度和骨质量下降导致骨强度减低,受到轻微外力甚至在日常活动中即可发生骨折。
Sextant微创椎弓根螺钉内固定:Sextant经皮椎弓根螺钉内固定,由于其特殊的连接杆置入技术,使对椎旁肌肉的扰动减到了最少的程度,真正实现了微创化概念。术中出血少,对脊柱周边肌肉组织干扰少,不需要大量剥离椎旁肌肉,创伤显著降低;恢复快,后遗症少,残留腰背痛和腰部乏力的机会显著降低。
 
摘要
背景:椎弓根螺钉内固定是修复骨质疏松性骨折常用的手法,通过内固定治疗可以有效重建椎体高度,恢复生理曲度,维持良好的脊柱稳定性。
目的:探讨微创经皮椎弓根螺钉Sextant内固定修复老年骨质疏松性脊柱骨折的生物相容性。
方法:纳入71例老年骨质疏松性脊柱骨折患者,均接受微创经皮椎弓根螺钉Sextant内固定治疗。利用C形臂X射线机对患者的骨折椎体进行准确定位,并于相应的体表进行标记。术中依次分离皮下组织以及筋膜层,利用Sextant螺钉进行内固定。术后12个月,予以内固定拆除。治疗后随访12个月,观察内固定置入后并发症发生情况以及内固定周围组织情况,治疗后1,3,6,12个月观察Cobb角、目测类比评分及Oswestry功能障碍指数变化。
结果与结论:①平均手术时间90.25 min,术中出血量85.15 mL;②治疗后不同时间,对患者的后凸 Cobb 角、目测类比评分、Oswestry功能障碍指数进行统计,可以发现各项指标均在治疗后1个月出现显著下降的情况,之后基本保持平稳状态。其中治疗后1,3,6,12个月的后凸 Cobb 角、目测类比评分、Oswestry功能障碍指数均显著小于治疗前(P < 0.05),治疗后不同时间各项指标差异均无显著性意义(P > 0.05);③术后有2例患者出现切口感染,经积极对症治疗后痊愈,未出现血栓等其他并发症。术后取钉时,对患者内固定周围组织情况进行观察,内固定周围未出现软组织炎性增生现象,且未观察到纤维囊壁形成和组织变黑等情况;④结果表明,微创经皮椎弓根螺钉Sextant内固定老年骨质疏松性脊柱骨折可以获得理想的修复效果,且具有良好的生物相容性。

Abstract:

BACKGROUND: Pedicle screw internal fixation is a commonly used method to treat osteoporotic fracture. Internal fixation can effectively reconstruct vertebral body height, restore physiological curvature, and maintain good spinal stability.

OBJECTIVE: To investigate the biocompatibility of minimally invasive percutaneous pedicle screw (Sextant) fixation in the treatment of elderly patients with osteoporotic vertebral fractures.
METHODS: A total of 71 cases of senile osteoporotic vertebral fractures were given minimally invasive percutaneous pedicle screw (Sextant) fixation for treatment. The C-arm X-ray machine was used to accurately locate the fracture vertebral body in different patients, and the corresponding surface was marked. In order to separate the subcutaneous tissue and fascia layer, the internal fixation with Sextant screw was used. 12 months after operation, the fixator was removed. The patients were followed up for 12 months, complications and tissues surrounding the fixator were observed. At 1, 3, 6, and 12 months after treatment, changes in Cobb angle, visual analogue scale score and Oswestry disability index were observed.
RESULTS AND CONCLUSION: (1) The average operation time was 90.25 minutes; intraoperative blood loss was 85.15 mL. (2) At different time points after treatment, Cobb angle, visual analogue scale score and Oswestry disability index of the patients were significantly decreased at 1 month after treatment, and maintained stable from then on. Cobb angle, visual analogue scale score and Oswestry disability index were significantly less at 1, 3, 6 and 12 months after treatment compared with that before treatment (P < 0.05). There was no significant difference in each indicator at different time points after treatment (P > 0.05). (3) Two patients affected wound infection, and were cured after symptomatic treatment. No complications such as thrombosis appeared. During removal of the screw, surrounding tissues were observed. There was no inflammatory hyperplasia of soft tissue around the fixator. No fibrous tissue or black wall was found. (4) These results confirm that Sextant minimally invasive pedicle screw internal fixation in elderly patients with osteoporotic vertebral fractures can obtain satisfactory therapeutic effect, and has good biocompatibility.
