Abstract
RESULTS: During the study period, 311 patients (79% M) underwent repair at a median age of 14 years (IQR 13-16). Median Haller index was 4 (IQR 3.5-4.9). Median duration of follow up was 3.8 years (range 0-16 years), reoperations were necessary in 26 (8%) patients and 23 (7%) patients experienced bar migration (of which 16 [5%] required reoperation, median time from repair of 26 days [IQR range 15-70]). Of the 101 (32%) patients who have had their bars removed electively, 10 (10%) required reoperation for recurrence (mean SD, 29 14 vs 46 25 months for non-recurrence, p1⁄40.036). Method of bar fixation was associated with reoperation: wire fixation (HR1⁄43.16, p1⁄40.014) and bar stabilizer (HR1⁄44.57, p1⁄40.002) use was associated with increased risk, while bilateral pericostal suture fixation with decreased risk (HR1⁄40.15, 95% CI: 0.06-0.40, p 50 cases1⁄4 <2%). Thoracoscopic assistance (78%) was associated with decreased risk of reoperation (HR 0.23, p<0.001). Survival free of reoperation at 1 and 5 years was 95% and 93%, respectively.
