背景：胫骨骨折传统外固定存在明显应力遮挡，骨折延迟愈合不愈合，聚醚醚酮树脂(polyetheretherketone， PEEK)材料弹性模量接近骨质，将有可能解决这一临床难题。<br> 目的：比较胫骨骨折采用新型PEEK复合材料外固定器和传统材料外固定器外固定治疗效果。<br> 方法：回顾分析胫骨骨折86例，男64例，女22例；年龄24-78岁，平均56岁；闭合性骨折30例，开放性骨折56例；平诊手术32例，急诊手术54例。所有患者根据外固定方法不同分为2组，分别采用新型PEEK复合材料外固定器和传统材料外固定器治疗。固定后定期复查X射线片，末次随访时根据Johner-Wruhs胫骨干骨折疗效评价标准评定功能恢复情况。<br> 结果与结论：所有患者固定后均获5-20个月随访。PEEK组平均8.7周拆除外固定器，4.2个月骨折愈合；传统材料外固定器平均10.6周拆除外固定器，6.1个月骨折愈合。末次随访时根据Johner-Wruhs胫骨干骨折疗效评价标准评定功能恢复情况：PEEK组优26例，良13例，差4例；传统材料外固定器优19例，良13例，差11例。结果表明，应用PEEK复合材料外固定器治疗不同类型胫骨骨折较传统材料外固定器治疗具有可保持骨折稳定、促进骨折愈合、利于患肢功能恢复的优势。
揹景：脛骨骨摺傳統外固定存在明顯應力遮擋，骨摺延遲愈閤不愈閤，聚醚醚酮樹脂(polyetheretherketone， PEEK)材料彈性模量接近骨質，將有可能解決這一臨床難題。<br> 目的：比較脛骨骨摺採用新型PEEK複閤材料外固定器和傳統材料外固定器外固定治療效果。<br> 方法：迴顧分析脛骨骨摺86例，男64例，女22例；年齡24-78歲，平均56歲；閉閤性骨摺30例，開放性骨摺56例；平診手術32例，急診手術54例。所有患者根據外固定方法不同分為2組，分彆採用新型PEEK複閤材料外固定器和傳統材料外固定器治療。固定後定期複查X射線片，末次隨訪時根據Johner-Wruhs脛骨榦骨摺療效評價標準評定功能恢複情況。<br> 結果與結論：所有患者固定後均穫5-20箇月隨訪。PEEK組平均8.7週拆除外固定器，4.2箇月骨摺愈閤；傳統材料外固定器平均10.6週拆除外固定器，6.1箇月骨摺愈閤。末次隨訪時根據Johner-Wruhs脛骨榦骨摺療效評價標準評定功能恢複情況：PEEK組優26例，良13例，差4例；傳統材料外固定器優19例，良13例，差11例。結果錶明，應用PEEK複閤材料外固定器治療不同類型脛骨骨摺較傳統材料外固定器治療具有可保持骨摺穩定、促進骨摺愈閤、利于患肢功能恢複的優勢。

BACKGROUND:Traditional external fixation of tibial fractures exhibits obvious stress shielding that delays fracture healing. Polyetheretherketone (PEEK) material has a similar elastic modulus to the bone, and it wil be possible to address this clinical problem. <br> OBJECTIVE:To compare the outcome of PEEK external fixator versus traditionaly external fixator in the treatment of tibial fractures. <br> METHODS:Clinical data of 86 patients with tibial fractures, including 64 males and 22 females, aged 24-78 years (mean age of 56 years), were retrospectively reviewed. There were 30 cases of closed fractures and 56 cases of open fractures; 32 cases received flat-patient surgery and 54 cases underwent emergency surgery. Al the patients were divided into two groups according to different fixation methods: PEEK group and traditional external fixator group. After operation, patients were checked regularly and at the last folow-up, functional recovery was evaluated according to Johner-Wruhs criteria. <br> RESULTS AND CONCLUSION:Al the patients were folowed up for 5-20 months. The mean fixator removal time of the PEEK group was 8.7 weeks and the mean duration of fracture healing was 4.2 months. The mean fixator removal time of the traditional external fixator group was 10.6 weeks and the mean duration of fracture healing was 6.1 months. At the last folow-up, in the PEEK group, 26 cases were assessed as excelent, 13 as good, 4 as poor; in the traditional external fixator group, 19 cases were assessed as excelent, 13 as good, 11 as poor. These findings indicate that PEEK external fixator for different types of tibial fractures can maintain the fracture stability, promote fracture healing and contribute to the functional recovery of the affected limbs.
