To explore the effect of a PEEK material-based external fixator in the treatment of distal radius fractures with non-transarticular external fixation.
There were 48 patients in this prospective comparative study. They were divided into two groups according to the materials used: the PEEK group and the titanium group. Wrist dorsiflexion, palmar flexion, pronation, supination, radial deviation, ulnar deviation, grip strength of the palm on the affected side, kneading force, Visual Analogue Scale/Score (VAS), Disabilities of the Arm, Shoulder, and Hand (DASH) score, operation time, frequency of fluoroscopy procedures, and X-ray results were compared between the two groups. Functional recovery was evaluated at the last follow-up according to the wrist joint evaluation criteria.
The baseline data were comparable between the two groups, and no significant differences were found in age, sex, fracture types (P > 0.05). There was no significant difference between the two groups in the results of DASH, grip strength, and recovery of pinch force and wrist function (dorsiflexion, clavicle, ulnar deviation, deviation, pronation, and supination) (P > 0.05). Normal limb function was achieved in the two groups of patients at an average of 6 weeks after surgery, and there was no significant difference in X-ray examination radial height (10.60 ± 1.59 vs 11.00 ± 1.53, P = 0.687), radial inclination (1.11 ± 0.24 vs 1.12 ± 0.24, P = 0.798), volar tilt (10.33 ± 2.13 vs 10.00 ± 2.08, P = 0.660), ulnar variance (20.87 ± 3.00 vs 20.38 ± 3.04, P = 0.748), and step-off persistence (1.73 ± 0.69 vs 1.68 ± 0.72, P = 0.425) between the two groups (P > 0.05). However, the operation time (54.80 ± 12.20 vs 85.23 ± 15.14, P = 0.033) and number of fluoroscopy procedures (36.93 ± 6.89 vs 64.77 ± 9.74, P = 0.000) in the PEEK group were significantly reduced compared with those in the titanium group.
Compared with the traditional titanium external fixator, the PEEK composite external fixator has advantages, such as a shorter operation time and fewer fluoroscopy procedures when used to treat different types of distal radius fracture.
探讨聚醚醚酮（PEEK）材料外固定架治疗非关节外桡骨远端骨折的效果。
前瞻性比较研究纳入 48 例患者，根据使用的材料分为 PEEK 组和钛组。比较两组患者腕背伸、掌屈、旋前、旋后、桡偏、尺偏、患侧手掌握力、捏力、视觉模拟评分（VAS）、上肢功能障碍评分（DASH）、手术时间、透视次数和 X 射线结果。末次随访时根据腕关节评价标准评估功能恢复情况。
两组患者的基线数据具有可比性，年龄、性别、骨折类型比较差异无统计学意义（P＞0.05）。两组患者 DASH 评分、握力、捏力和腕关节功能（背伸、尺偏、桡偏、旋前、旋后）恢复情况比较差异无统计学意义（P＞0.05）。两组患者术后平均 6 周均获得正常肢体功能，X 射线检查桡骨高度（10.60±1.59 比 11.00±1.53，P=0.687）、桡骨倾斜角（1.11±0.24 比 1.12±0.24，P=0.798）、掌倾角（10.33±2.13 比 10.00±2.08，P=0.660）、尺侧骨间隙（20.87±3.00 比 20.38±3.04，P=0.748）和台阶征（1.73±0.69 比 1.68±0.72，P=0.425）差异无统计学意义（P＞0.05）。但 PEEK 组手术时间（54.80±12.20 比 85.23±15.14，P=0.033）和透视次数（36.93±6.89 比 64.77±9.74，P=0.000）明显少于钛组。
与传统钛外固定架相比，PEEK 复合材料外固定架治疗不同类型桡骨远端骨折时，具有手术时间更短、透视次数更少的优点。
