Objective:
To compare the outcomes and complications of bone transport over a nail (BTON) with those of bone transport over a plate (BTOP) for segmental tibial bone defects.
Design:
Retrospective matched study design.
Setting:
A major metropolitan tertiary referral trauma center.
Patients:
Thirty-six patients with segmental tibial bone defects of >4 cm were included in this study.
Intervention:
Either BTON or BTOP was performed on 18 patients.
Main Outcome Measurements:
We compared the healing of the distraction process and of the docking site between the techniques. Distraction parameters including external fixator (EF) time, external fixation index, and healing index were compared. Bone and functional results were compared according to the Paley-Maar classification. Complications associated with each procedure were compared.
Results:
Both BTON and BTOP achieved similar rates of primary union (83% vs. 89%) at the distraction or docking site. Significantly less time wearing an EF was needed for BTOP than for BTON (2.8 vs. 5.4 months; P < 0.01). The external fixation index was significantly lower for BTOP than for BTON (0.45 vs. 0.94 mo/cm; P < 0.01), whereas the healing indexes were similar. The final outcomes and complication incidences were not significantly different.
Conclusions:
The EF time was significantly shorter for BTOP than for BTON; however, the final outcomes were similar. Therefore, BTOP could be considered an attractive option for bone transport in patients with segmental tibial defects.
