To investigate the effectiveness of simultaneous treatment of traumatic calcaneal osteomyelitis and defect deformity with near-arc bone transport by Ilizarov technique.Between January 2014 and August 2020, 6 cases of traumatic calcaneal osteomyelitis with defect deformities were treated by simultaneous treatment of near-arc bone transport by Ilizarov technique. The patients were all male; aged from 40 to 61 years (mean, 49.3 years). The disease duration was 2-72 months, with an average of 16.1 months. All patients were traumatic calcaneal osteomyelitis, including 4 cases of falling from height, 1 case of traffic accident injury, and 1 case of crushing injury. The infection affected the talar-heel joint in 4 cases, and the talar-heel joint was fused or partially fused in 2 cases. After the external fixator was removed, the Maryland foot scoring system was used to evaluate the foot function, and the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot function scoring system was used to evaluate the ankle-hindfoot function, and were compared with the preoperative scores.All patients were followed up 1.5-26.0 months, with an average of 16.3 months. All incisions healed by first intention, no recurrence of infection occurred, and no surgical intervention such as second-stage bone grafting and fusion was performed. Five cases of calcaneal osteomyelitis with defect deformity underwent one-stage osteotomy and slipped, 1 case of the original bone mass after debridement after infection of calcaneal fractures slipped directly. The bone sliding time was 28-62 days, with an average of 38.7 days; the sliding distance was 3.1-5.2 cm, with an average of 3.6 cm. In 1 patient, due to the short follow-up time, the calcaneal slip bone had not healed, the external fixator had not been removed (not involved in clinical scoring), but the foot shape, reexamination of X-ray films and with frame walking were satisfactory. The time with external fixator was 6-8 months, with an average of 6.5 months in the other 5 cases. After removing the external fixator, the foot returned to three-point weight-bearing, and the longitudinal arch was recovered to varying degrees, and there was no obvious varus valgus. The Maryland score after removal of the external fixator was 80.8±4.7, which was significantly higher than that before operation (33.6±4.3) (Simultaneous treatment of traumatic calcaneal osteomyelitis and defect deformity with near-arc bone transport by Ilizarov technique can optimize the operation method, reduce the number of operations, and try to simulate the original shape of the calcaneus. It is an effective, economical, and novel treatment method.探讨应用 Ilizarov 技术近弧形骨块滑移同期治疗创伤性跟骨骨髓炎并缺损畸形的临床疗效。.2014 年 1 月—2020 年 8 月，结合 Ilizarov 技术使骨块近弧形滑移同期治疗创伤性跟骨骨髓炎并缺损畸形 6 例。患者均为男性；年龄 40～61 岁，平均 49.3 岁。病程 2～72 个月，平均 16.1 个月。均为外伤导致跟骨骨髓炎，其中高处坠落伤 4 例、交通事故伤 1 例、砸伤 1 例。感染波及距跟关节 4 例，距跟关节已融合或部分融合 2 例。拆除外固定架后采用 Maryland 足部评分系统评价足部功能，美国矫形足踝协会（AOFAS）踝-后足功能评分系统评价踝-后足功能，并与术前评分比较。.术后患者均获随访，随访时间 1.5～26.0 个月，平均 16.3 个月。患者术后切口均Ⅰ期愈合，无感染复发，均未行二期植骨融合等手术。跟骨骨髓炎伴缺损畸形一期截骨滑移 5 例，跟骨骨折感染清创术后原骨块病灶清除后直接滑移 1 例；骨块滑移时间 28～62 d，平均 38.7 d；滑移距离 3.1～5.2 cm，平均 3.6 cm。1 例患者因术后时间较短，跟骨滑移部骨质尚未愈合，未拆除外固定架（未参与临床评分），但足部外形、复查 X 线片及带架行走等情况满意。其余 5 例带架时间为 6～8 个月，平均 6.5 个月。拆除外固定架后可见足部恢复三点着力负重，纵弓可见不同程度恢复，未出现明显内外翻。Maryland 评分为（80.8±4.7）分，较术前（33.6±4.3）分显著改善（应用 Ilizarov 技术近弧形骨块滑移同期治疗创伤性跟骨骨髓炎并缺损畸形可以优化手术方式，减少手术次数，尽量模拟跟骨原形态重建，是一种有效、经济、新颖的治疗方法。. |
