Abstrakt: Objective: Bone transport has become the gold standard for treating large segmental tibial bone defects. The technique for application the Ilizarov circular fixator (ICF) has a long learning curve and is associated with many complications. There are few clinical studies on bone transport via the Taylor spatial frame (TSF). The main purpose of this study was to compare the radiological and clinical and outcomes of bone transport by using the TSF and the ICF.
Methods: There were 62 patients included in this retrospective study from June 2011 to June 2021 and distributed to two groups according to the fixation method: a TSF group consisting of 30 patients and an ICF group consisting of 32 patients. Demographic information, surgical duration, external fixation times, external fixation index, final radiographic results, complications, and clinical outcomes were recorded and examined. The clinical outcomes were assessed using the ASAMI criteria during the most recent clinical visit. Then, statistical analysis such as independent-samples t tests or chi-Square test was performed.
Results: The mean surgical duration in the TSF group was 93.8 ± 7.3 min, which was shorter than that in the ICF group (109.8 ± 1.4 min) (p < 0.05). Compared to the ICF group (10.2 ± 2.0 months), the TSF group (9.7 ± 1.8 months) had a shorter average external fixation time (p > 0.05). The external fixation index was 1.4 ± 0.2 m/cm and 1.5 ± 0.1 m/cm in the two groups. Moreover, there was no significant difference between the two groups. At the last follow-up visit, the medial proximal tibial angle (MPTA) and posterior proximal tibial angle (PPTA) in the TSF group were 88.1 ± 12.1° and 80.9 ± 1.3°, respectively. The MPTA and PPTA in the ICF group were 84.4 ± 2.4° and 76.2 ± 1.9°, respectively. There were statistically significant differences between the two groups (all p < 0.05). The complication rate was 50% in the TSF group and 75% in the ICF group. Moreover, the ASAMI score between the two groups was no statistically significant difference (p > 0.05).
Conclusion: No statistically significant difference was found in clinical outcomes between the use of Taylor spatial frame and Ilizarov circular fixator for treating large segmental tibial bone defects. However, TSF is a shorter and simpler procedure that causes fewer complications and improves limb alignment.
