Abstract Background: Retraction of transporting bone segment (TBS) may occur when the fixator of the TBS is removed prior to full consolidation of the distracted callus, which has adverse effect on the healing of the docking site. However, there are few reports on the retraction of TBS. The purpose of this study is to analyze the causes and risk factors of the retraction of TBS. Methods: The clinical data of 37 cases with tibial bone defect treated by Ilizarov bone transport were analyzed retrospectively, in whom the TBS fixator was removed prior to full consolidation of the distracted callus and union of the docking site. Bivariate correlation was used to analyze relationship between the retraction distance of TBS and potential risk factors including age, gender, course, length of bone defect, number of operations, size of TBS, transport distance, timing and time interval of removal of TBS fixator. Risk factors with significant level were further identified using multivariate linear regression. Results: Bivariate correlation showed that the timing of removal was negatively correlated with the retraction distance, and the time interval and transport distance were positively correlated with the retraction distance（p<0.05), the age, gender, course, length of bone defect, size of TBS and number of operations were not correlated with the retraction distance（p>0.05). Multivariate linear regression of the 3 risk factors showed that the timing of removal and time interval were the main risk factors affecting the retraction distance (p<0.05), but the transport distance was not (p>0.05). Conclusion: The traction forces of TBS endured from the soft tissues and the unconsolidated distracted callus have elastic properties, which can make retraction of TBS. The timing of removal and time interval are the main risk factors of the retraction of TBS. In the case of early removal, another external fixation or quickly converted to internal fixation should be performed to avoid the adverse effect of more retraction.

Abstract Background: Retraction of transporting bone segment (TBS) may occur when fixator of TBS is removed before complete mineralization of the distraction callus and union of the docking site. However, there are few reports on the causes and influencing factors of the retraction of TBS.Methods: The clinical data of 37 cases with tibial bone defect treated by Ilizarov bone transport were analyzed retrospectively, in whom the fixator of TBS was removed before maturing of mineralization of the distraction callus and union of the docking site. Bivariate correlation was used to analyze relationship between retraction distance of TBS and factors including age, gender, disease course, length of bone defect, times of operation, size of TBS, transport distance, timing and time interval of removal of TBS fixator. Risk factors with significant level were further identified using multivariate linear regression. Results: Bivariate correlation analysis showed that the timing of removal was negatively correlated with the retraction distance while the time interval, transport distance were positively correlated with the transport distance（all p<0.05); the age, gender, disease course, length of bone defect, size of TBS and times of operation were not correlated with the transport distance（p>0.05). Multivariate linear regression analysis of the 3 risk factors showed that the timing of removal and time interval were the main risk factors for the retraction distance (p<0.05), of which, the timing of removal had the greatest impact, followed by the time interval, but the transport distance was not a main risk factor for the retraction distance (p>0.05).Conclusion: The TBS is subjected to distraction force from all the adherent soft tissues during Ilizarov bone transport, which has elastic properties and can make a retraction of TBS when its fixator is removed before complete mineralization of the distraction callus and union of the docking site. The timing of removal and the time interval are key factors influencing the retraction of TBS.

Abstract Background: Previous research rarely reported the cause and relevant factors of retraction of transporting bone segment (TBS). The purpose of this study is to analyze the force and cause of retraction of TBS during Ilizarov bone transport after removal of its fixator. Methods: 37 cases with tibial bone defect treated by Ilizarov bone transport, in whom the fixator of TBS was removed before mature of mineralization of the distraction callus or union of the docking site, were analyzed retrospectively. Bivariate correlation was used to analyze relationship between retraction distance of TBS and age, gender, disease course, length of bone defect, times of pre-operation, size of TBS, transport distance, cause of removal, timing and time interval of removal of TBS fixator. Risk factors with significant level were further identified using multivariate linear regression. Results: Bivariate correlation analysis showed the timing of removal was negatively correlated while the time interval, cause of removal, transport distance and size of TBS were positively correlated with the transport distance（all p<0.05), however the age, gender, disease course, length of bone defect and times of pre-operation were not correlated with the transport distance（p>0.05). Multivariate linear regression analysis showed the timing of removal, transport distance and size of TBS were significant risk factors for the retraction distance (p<0.05), of which, the timing of removal had the greatest impact, followed by the transport distance and size of TBS, however the cause of removal and time interval were not significant for the retraction (p>0.05). Conclusion: The traction force of the TBS endured from soft tissue , not from the distraction callus, is elastic and can induce a retraction of TBS when its fixator is removed in advance. The retraction distance is related to the size of TBS, transport distance and timing of removal, especially the timing of removal is an independent risk factor.

Abstract Objective To investigate the cause and relevant factors of retraction of transporting bone segment (TBS) after removal of its fixator during Ilizarov bone transport. Methods The clinical data of 37 cases with tibial bone defect treated by Ilizarov bone transport, in whom the TBSs were removed before mature of mineralization of the distraction callus and union of the docking site, were analyzed retrospectively. Bivariate correlation was used to analyze relationship between retraction distance of TBS and age, gender, disease course, length of bone defect, times of pre-operation, size of TBS, transport distance, cause of removal, timing and time interval of removal of TBS fixator. Risk factors with significant level were further identified using multivariate linear regression. Results Bivariate correlation analysis showed that the timing of removal was negatively correlated with the retraction distance, the time interval, cause of removal, transport distance and size of TBS were positively correlated with the transport distance(all p<0.05), whereas the age, gender, disease course, length of bone defect and times of pre-operation were not correlated with the transport distance(p>0.05). Multivariate linear regression analysis of the 5 risk factors showed that the timing of removal, transport distance and cause of removal were independent risk factors for the retraction distance (p<0.05), of which, the timing of removal had the greatest impact, followed by the transport distance and cause of removal. The transport distance and time interval were not significant for the retraction (p>0.05). Conclusion The TBS is subjected to distraction force from all the adherent soft tissues during Ilizarov bone transport, which has elastic properties and can make a retraction of TBS if its fixator is removed before mature of mineralization of the distraction callus and union of the docking site. The retraction distance is related to the TBS size, transport distance, timing and time interval of removal of TBS fixator. Importantly, the timing of removal and transport distance are the main factors for the retraction, especially the timing of removal had the greatest impact.

Abstract Background Post-traumatic tibial osteomyelitis is considered as complex clinical problem due to its unique characteristics such as prolonged course, multi-staged treatment and high recurrence rate. The purpose of this study is to identify and analyze the causes and risk factors associated with infection recurrence of tibial osteomyelitis treated with Ilizarov technique. Methods From January 2011 to January 2019, a total of 149 patients with post-traumatic tibial osteomyelitis treated with Ilizarov bone transport technique were included in this study. Demographic and clinical data were collected and analyzed. Univariate analysis and logistic regression analysis were used to analyze the factors that may affect the recurrence or reinfection of post-traumatic tibial osteomyelitis after treated with Ilizarov bone transport technique. Results All included patients were successfully followed up with an average of 37.5 month (18–78 month), among them, 17 patients (11.4%) occurred with recurrence or reinfection of tibial osteomyelitis in which 2 cases were in distraction area and 15 cases in docking site. Among them, 5 patients were treated successfully with appropriate intravenous antibiotic, the remaining 12 patients were intervened by surgical debridement or bone grafting after debridement. Univariate analysis showed that Pseudomonas aeruginosa infection, bone exposure, number of previous operations (> 3 times), blood transfusion during bone transport surgery, course of osteomyelitis > 3 months, diabetes was associated with recurrence or reinfection of postoperative tibial osteomyelitis. According to the results of logistic regression analysis, Pseudomonas aeruginosa infection, bone exposure, and the number of previous operations (> 3 times) are risk factors for recurrence or reinfection of posttraumatic tibial osteomyelitis treated with Ilizarov bone transport technique, with odds ratios (OR) of 6.055, 7.413, and 1.753, respectively. Conclusion The number of previous operations (> 3 times), bone exposure, and Pseudomonas aeruginosa infection are risk factors for infection recurrence of posttraumatic tibial osteomyelitis treated with Ilizarov bone transport technique.

Distraksi osteogenesis dan pemanjangan tulang telah digunakan untuk merekonstruksi hilangnya tulang dengan memungkinkan tulang baru terbentuk pada celah. Pada penelitian sebelumnya, pemanjangan tulang yang dipandu pelat telah berhasil mengobati hilangnya  tulang pada tulang paha, tibia, dan mandibula. Penelitian ini melaporkan sebuah kasus fraktur tibia dengan kehilangan tulang kominutif yang diobati dengan fiksasi pelat dan pemanjangan tulang dengan fiksator cincin Ilizarov. Pada saat pengaitan, ketika segmen pemanjangan dikompresi dengan fragmen tulang, fragmen tulang difiksasi dengan sekrup locking dan non-locking tambahan melalui pelat. Panjang defek tulang adalah 7 cm. Indeks pemanjangan atau fiksasi eksternal adalah 12,7 hari / cm. Pada kasus ini tidak ada pemendekan yang terjadi. Indeks konsolidasi radiografi rata-rata adalah 37 hari / cm. Kasus ini  mencapai regenerasi segmen tulang yang bebas infeksi dan hasil fungsional yang memuaskan. Teknik ini mengurangi durasi fiksasi eksternal selama fase konsolidasi, memungkinkan koreksi panjangtulang, dan penyelarasan dan waktu rehabilitasi yang lebih singkat.\Kata kunci: Defek Tulang, Transportasi Tulang, Osteogenesis Gangguan, Teknik Ilizarov, Osteogenesis Lempeng TulangOsteogenesis distraction and bone transport has been used to reconstruct bone loss defect by allowing new bone to form in the gap. In previous studies, plate-guided bone transport has been successfully to treat bone loss defect in the femur, tibia, and mandible. This study reports a case of fracture of tibia with comminutive bone loss treated with plate fixation and bone transport with Ilizarov ring fixator. At the time of docking, when the transport segment is compressed with bone fragment, the bone fragment is fixed with additional locking or nonlocking screws through the plate. The bone defect size was 7 cm. The lengthening/external fixation index was 12.7 days/cm. In this case there were no shortening that  present. The average radiographic consolidation index was 37 days/cm. This case achieved infection-free bone segment regeneration and satisfactorily functional outcome. This technique reduces the duration of external fixation during the consolidation phase, allows correction of length and alignment and provides earlier rehabilitation.Keywords: Bone Defect, Bone Transport, Distraction Osteogenesis, Ilizarov Technique, Bone Plate Osteogenesis

The Difference

Aims Many authors have reported a shorter treatment time when using trifocal bone transport (TFT) rather than bifocal bone transport (BFT) in the management of long segmental tibial bone defects. However, the difference in the incidence of additional procedures, the true complications, and the final results have not been investigated. Patients and Methods A total of 86 consecutive patients with a long tibial bone defect (≥ 8 cm), who were treated between January 2008 and January 2015, were retrospectively reviewed. A total of 45 were treated by BFT and 41 by TFT. The median age of the 45 patients in the BFT group was 43 years (interquartile range (IQR) 23 to 54). Results The size of the bone defect was significantly longer (p = 0.005), the number of previous operations was significantly higher (p < 0.001), the operating time was significantly longer (p < 0.001), and the bone transport distance was significantly increased (p = 0.017) in the TFT group. However, the external fixation time (p < 0.001), the healing index (p < 0.001), the number of additional procedures (p = 0.013), and the number of true complications (p < 0.001) were significantly reduced in this group. Both groups achieved highly satisfactory bone and functional results. Conclusion TFT can significantly reduce the treatment time, the number of additional surgical procedures, and true complications compared with BFT in the treatment of long segmental tibial bone defects.
