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: 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 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 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.
