Abstract：

Objective To discuss the therapeutic effect of distraction osteogenesis for large bone defect of the lower extremity. Methods From August 2002 to August 2010, 11 patients with large bone defect at the lower extremity were treated with distraction osteogenesis. They were 10 men and one woman, aged from 14 to 53 years (average, 34. S years). The defect was at the right tibia in 7 cases, left tibia in 3 cases and right femur in one case. The lengths of bone defect ranged from 5 to 15 cm (average, 8. 6 cm). Results The patients were followed up for 7 to 48 months, with a mean period of 27. 3 months. The treatment of 9 cases was over, with a mean healing index of 1. 99 months/cm. According to the Paley evaluation system, the bony results were excellent in 6 and good in 3 patients; the functional results were excellent in 4, good in 4, and fair in one patient. Two cases were still in the mineralization period. Conclusion Treatment of large bone defects with distraction osteogenesis is simple and can obtain satisfactory therapeutic effects, especially when a monolateral external fixator is used for the simple shaft bone defect.

Bone Transport for Reconstruction in Benign Bone Tumors

Background

The aim of this study was to assess the results of using the Ilizarov apparatus to transport bones in the treatment of benign bone tumors.

Methods

Seven patients (six males and one female) with benign bone tumors were treated by bone transport with an Ilizarov apparatus at our institution. Their mean age at surgery was 14.4 years (range, 4.8 to 36.9 years). The histological diagnoses were osteofibrous dysplasia (4), giant-cell tumor (1), intraosseous cavernous hemangioma (1), and aneurysmal bone cyst (1). Three radiological indices were used for evaluating the results: an external fixation index, a distraction index, and a maturation index. The bone and functional results were evaluated according to the Association for the Study and Application of the Method of Ilizarov classification.

Results

Five patients had bone union at the reconstructed site, one patient had a local recurrence, and the other had a nonunion at the docking site. The mean length of distraction was 7.3 cm (range, 5.1 to 12.1 cm). The mean external fixation index was 26.0 day/cm (range, 19.8 to 32.5 day/cm), the distraction index was 9.6 day/cm (range, 6.8 to 12.0 day/cm), and the maturation index was 14.9 day/cm (range, 8.0 to 22.5 day/cm). Ultimately, the bone and the functional results were rated excellent in six cases and good in one case.

Conclusions

Bone transport using the Ilizarov apparatus is a good treatment option in patients with bone defects after the resection of an active or aggressive benign bone tumor.

Ilizarov骨搬移技术在胫骨骨折术后骨感染骨缺损中的应用

目的探讨Ilizarov骨搬移技术治疗胫骨骨折术后骨感染骨缺损的临床疗效。方法回顾性分析自2010-06—2013-06应用Ilizarov骨搬移技术治疗27例胫骨骨折术后骨感染。结果 27例术后均获得平均28(16~50)个月随访。骨搬移长度平均7.9(5~12)cm,搬移时间平均78(55~160)d,骨搬移停止至拆除外固定架时间平均180(95~220)d。出现针道感染2例,停止搬移,静点抗生素、对症处理后感染控制;出现牵张成骨区成骨不全1例,植骨后愈合;拆除外架后发生牵张成骨区骨折1例,经内固定后骨愈合;骨搬移停止后,对15例断端进行去除嵌压组织、新鲜化处理后断端骨性愈合,9例无需进一步手术,通过断端加压后骨愈合,3例加压固定3个月后无明显愈合表现,按照骨不连处理方案,应用手风琴技术处理后顺利愈合。结论应用Ilizarov骨搬移技术治疗胫骨骨折术后骨感染骨缺损可以取得满意的疗效,骨搬移过程中的环形固定器有利于畸形矫正,但患者对单边固定器有更好的耐受性。严谨的术前设计、精细的术中操作、耐心细致的术后随访是治疗成功的必要保证。     

Bone transport for the management of severely comminuted fractures without bone loss

This study aims to provide a new method for treatment of severely comminuted fractures without bone loss using the well-known technique of bone transport. Sixteen patients suffering from severely comminuted fractures with closed soft tissue injury were prospectively treated using bone transport by Ilizarov circular fixator. There were 14 male and 2 female patients. The mean age was 36.5 years (27–45). There were 13 proximal tibial metaphyseal fractures, one tibial diaphyseal fracture and two femoral distal metaphyseal fractures. All patients had closed soft tissue. The mean length of the comminution gap was 50.3 mm (40–64). Fracture healing occurred in 15 patients. The mean healing time was 23.4 weeks (14–30). No bone stimulating procedures were needed for either the fracture or distraction site. Using the IOWA knee and ankle score for assessment of the 15 patients who completed treatment: the functional outcome for the knee was excellent in 11 patients, good in three and fair in one. The ankle score was excellent in 12 patients, good in two and fair in one. According to Paley and Maar’s, bone results were excellent in 14 patients, good in one patient and poor in the patient who had failure of the procedure. The results achieved in this work are encouraging to keep on applying this technique to treat fractures that meet the following criteria: metaphyseal, with total circumferential comminution involving more than 4 cm of the bone length.

四肢开放性骨折伴骨缺损治疗方法的研究

目的 探讨一种简单、安全、有效的治疗开放性骨折伴骨缺损方法。方法 对98例开放性骨折伴骨缺损的病人在清创,适当固定后采用：①载药自固化磷酸钙人工骨植入;②抗生素伴自体骨植入;③早期关闭创口,后期取带血管蒂的骨块伴载药自固化磷酸钙人工骨植入。结果 对轻中度污染,骨缺损量较少的开放性骨折伴骨缺损者,采用载药自固化磷酸钙人工骨植入及抗生素伴自体骨植入治疗,二者无明显差异。对污染较重的开放性骨折伴骨缺损者,适用于载药自固化磷酸钙植入治疗。对污较重且伴有节段性缺损大于5cm的开放性骨折伴骨缺损者,适用于早期清创,后期取带血管蒂的骨块伴载药自固化磷酸钙人工骨植入治疗。结论 对开放性骨折伴骨缺损,应根据骨缺损量的多少及污染的程度选用合适的方法,以免多次手术。

Clinical Guideline for Microwave Ablation of Bone Tumors in Extremities

Microwave ablation has been used to treat bone tumors in extremities for more than 30 years. With improved recognition, updated microwave equipment, and expanded clinical application, microwave ablation has recently been widely used to treat bone tumors. To standardize the application of microwave ablation in the clinical treatment of bone tumors in the limbs, research results and clinical experience involving the use of microwave ablation to treat bone tumors in the limbs have been summarized, and a clinical guideline has been designed. This guideline is aimed at providing a reliable clinical basis for indications, preoperative evaluation and decision‐making, perioperative treatment, complications, and other issues via evidence‐based medicine. Two aspects are considered—percutaneous microwave ablation and intraoperative microwave ablation of bone tumors in extremities. Ultimately, the guideline is intended to standardize treatment and improve the clinical efficacy of microwave ablation of bone tumors in extremities.
