Abstract
OBJECTIVE: The objective of this study was to evaluate the effectiveness of the treatment of infected forearm nonunion by bone transport. MATERIALS AND METHODS: We retrospectively reviewed 16 patients with infected forearm nonunion treated by bone transport. Our study included 10 males and 6 females with a mean of age 38.25 years. The site of bone defects involved 9 radius and 7 ulna. The average length of the bone defects after radical debridement was 3.81cm (range 2.2-7.5cm). RESULTS: The mean follow-up after removal of the frame was 39.63 months (range 26-55 months). No patient was lost to follow-up. All the patients had bone union and no recurrence of infection was observed. The mean external fixation time was 6.19 months (range 3-10 months), and the mean external fixation index was 1.63 months/cm (range 1.14-2.00 months/cm). The mean degrees of wrist flexion were 49.69° (range 45-55°), and the mean degrees of wrist extension were 50.63° (range 40-60°). The mean degrees of elbow flexion were 143.12° (range 135-150°), and the mean degrees of elbow extension were 4.69° (range 0-20°). The mean degrees of forearm pronation were 82.50° (range 70-90°), and the mean degrees of forearm supination were 83.75° (range 75-90°). CONCLUSION: Our study suggested that bone transport in the treatment of infected forearm nonunion acquired satisfied functional results. Radical debridement is the key step to control bone infection.
