摘要:

文题释义:

可吸收棒、钛合金螺钉内固定两者均属于MasonⅡ型桡骨头骨折螺钉内固定法,主要区别在于其制作材质不一样,前者是由聚乳酸制成的可吸收高分子聚合物,而后者为钛合金制成,需二次手术取出。

桡骨头骨折Mason分类Ⅰ型,为线状骨折,即无移位型骨折,骨折线可通过桡骨头边缘或呈劈裂状;Ⅱ型,为有移位的骨折,有分离的边缘骨折;Ⅲ型,为粉碎型骨折,移位或无移位或呈塌陷性骨折;Ⅳ型,为桡骨头骨折伴有肘关节脱位。

背景:目前切开复位内固定是治疗MasonⅡ型桡骨头骨折的有效方法,内固定的选择有螺钉、微型钢板、克氏针、可吸收棒或钉等,临床疗效报道不一致。

目的对比可吸收棒或钛合金螺钉内固定治疗MasonⅡ型桡骨头骨折的临床疗效。

方法选择20161月至20172月四川省人民医院收治的桡骨头骨折患者25例,其中男16例,女9例,年龄38-61岁,均进行切开复位内固定治疗,其中13例的内固定材料为钛合金螺钉,另12例的内固定材料为可吸收棒。术后随访拍摄X射线片,确定骨折愈合时间。末次随访时,对比两组目测类比评分、肘关节活动度及肘关节功能Mayo评分与Broberg-Morrey 评分。该研究已通过四川省医学科学院·四川省人民医院伦理委员会的审批。

结果与结论:①可吸收棒组、钛合金螺钉组的骨折愈合时间分别为(2.35±0.92),(2.10±0.47)个月,组间比较差异无显著性意义(P > 0.05);②末次随访时,两组间肘关节功能Mayo评分与Broberg-Morrey 评分比较差异均无显著性意义(P > 0.05);③末次随访时,两组间肘关节屈曲、伸直、旋后、旋前角度比较差异均无显著性意义(P > 0.05);④末次随访时,两组目测类比评分比较差异均无显著性意义(P > 0.05);⑤结果表明,可吸收棒与钛合金螺钉治疗MasonⅡ型桡骨头骨折的临床疗效相似,但可吸收棒避免了二次手术取出内固定及应力性遮挡等情况。

Abstract:

BACKGROUND: At present, open reduction and internal fixation is an effective method for the treatment of Mason type II radial head fracture. The selection of internal fixation includes screws, micro plates, Kirschner wires, absorbable rods or nails. The clinical efficacy reported is inconsistent.

OBJECTIVE: To compare the clinical efficacy of titanium alloy screws or absorbable rod for the internal fixation of Mason type II radial head fractures.

METHODS: Totally 25 patients with radial head fractures were collected from January 2016 to February 2017 in Sichuan Provincial People’s Hospital, including 16 males and 9 females, at the age of 38-61 years. All



patients received open reduction and internal fixation. Of them, 13 cases received titanium alloy screws, and 12 cases received absorbable rod. X-ray images were obtained during follow-up to identify fracture healing time. During the final follow-up, visual analogue score, elbow motion range, Mayo elbow joint function score and Broberg-Morrey scores were compared between the two groups. The study was approved by the Ethics Committee of Sichuan Provincial People’s Hospital·Sichuan Academy of Medical Sciences.

RESULTS AND CONCLUSION: (1) There was no significant difference in fracture healing time between the absorbable rod group (2.35±0.92 months) and titanium alloy screw group (2.10±0.47 months) (P > 0.05). (2) In the final follow-up, there was no significant difference in Mayo elbow joint function score and Broberg-Morrey scores between the two groups (P > 0.05). (3) In the final follow-up, there was no significant difference in elbow flexion, extension, supination, and pronation angle between the two groups (P > 0.05). (4) In the final follow-up, there was no significant difference in visual analogue score between the two groups (P > 0.05). (5) These results indicate that the absorbable rod and titanium alloy screws can obtain satisfactory treatment outcomes for Mason type II radial head fractures. However, the absorbable rod can avoid the secondary operation for removing internal fixators, and the adverse impact of stress shielding.

Key words: absorbable rod, titanium alloy screw, Mason type II radial head fracture, tissue engineering, radius, elbow joint
