Out of a total of 40 patients affected with Blount's disease treated at the Pediatric Orthopaedic Division of the Rizzoli Orthopaedic Institute between 1965 and 1996, 29 were affected with the infantile type, and 11 with the adolescent type. In the group affected with infantile Blount's disease, the mean age was 5.5 years, 11 were bilateral, for a total of 40 limbs affected, with a mean TMD angle of 24 degrees. All of the patients were treated by valgus osteotomy obtaining a percentage of poor results (insufficient correction or recurrence) equal to 25% according to Schoenecker's criteria. Mean follow-up was 3.6 years. In the group affected with adolescent Blount's disease, mean age was 12.6 years, the affection was always monolateral, the mean TMD angle was 15 degrees. All of the patients except 1 were treated by valgus osteotomy with elevation, and the results were constantly favorable. Mean follow-up was 2 years. The authors believe that the type of osteotomy used must be modulated based on the anatomopathologic findings of compromise in the proximal tibial metaepiphysis.
1965年至1996年间，在里佐利骨科研究所小儿骨科接受治疗的40例布朗特病患者中，29例为婴儿型，11例为青少年型。在婴儿型布朗特病组中，平均年龄为5.5岁，11例为双侧患病，共计40条肢体受累，平均胫骨内侧干骺端角（TMD角）为24度。所有患者均接受外翻截骨术治疗，根据舍内克标准，治疗效果不佳（矫正不足或复发）的比例为25%。平均随访3.6年。在青少年型布朗特病组中，平均年龄为12.6岁，病变均为单侧，平均TMD角为15度。除1例患者外，所有患者均接受了抬高外翻截骨术治疗，结果一直良好。平均随访2年。作者认为，所采用的截骨术类型必须根据胫骨近端干骺端受损的解剖病理学结果进行调整。
