Abstract:
Objective:To evaluate the effect of "accordion" technique on promoting bony union at the docking site in the treatment of tibial bone defects by bone transport.Methods:A retrospective study was conducted to analyze the data of 11 patients with tibial bone infection who had been admitted to Department of Orthopedics, The Second Hospital of Shanxi Medical University from November 2017 to February 2019. There were 10 males and 1 female with an age of (47.0±9.7) years. Seven patients were infected after internal/external fixation for open fractures and 4 cases after internal fixation for closed fractures. After surgical debridement, sensitive antibiotic bone cement was implanted, and dead or infected bone segments were radically resected. In all patients, the resulting bone defects of (6.6±2.9) cm were fixated by an Ilizarov ring external fixator and filled by bone transport. The "accordion" technique was used after the bone segments touched the docking site. The closure time, "accordion" time, bony union time and complications during bone transport were recorded.Results:None of the patients underwent bone grafting. This case series was followed up for (2.7±0.5) years. The closure time was (30.8±6.8) weeks, the "accordion" time (43.1±8.4) days, and the bony union time (31.6±9.0) weeks. None of the patients had obvious pain. Ankle stiffness was observed in 3 patients and traumatic equinus deformity in 1 patient.Conclusions:The "accordion" technique based on the Illizarov technique can accelerate mineralization of the bone segments transported, promote the bony union at the docking site, and effectively solve the problem of tibial bone defects without surgical bone grafting.
