Treatment of traumatic bone defects by bone transport
Abstract
This study retrospectively evaluates the results of the management using the callus distraction method, of 19 patients who had developed bone defects following acute trauma. Sixteen patients were males, with a mean age of 19.4 years (6-41 years). Thirteen patients developed bone defects as a result of high-velocity gunshot injuries, and six had defects caused by traffic accidents. The location of 12 fractures was the tibia, and seven were in the femur. The mean follow-up period was 23.6 (12-40) months. The mean length of the bone defect was 6.8 cm (4-16 cm), the distraction index was 13.3 days/cm (7.5-18 days/cm) and the external fixation index was 36.6 days/cm (32.5-46 days/cm). Fifteen (9%) pintract infections were observed among those who underwent circular external fixation and four (10%) in cases who underwent unilateral external fixation. There were no deep infections. Refracture was noted in one patient (5%), and two (11%) had delayed union at the target site. One patient developed nonunion at the target site. For the treatment of large bone defects, the callus distraction method may be an alternative option to conventional treatment methods.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 19 participants or records.
