Blount's disease is an uncommon disorder of postero-medial proximal tibial physis. Blount described infantile and adolescent types. This study aims to describe using femur, tibia and fibula osteotomies to treat infantile Blount's disease. From May 1992 to May 2005, 7 patients of Blount's disease (3 males, 4 females) were included, whose age was range from 17 to 62 months. Femorotibial angle (FTA) was 31 ± 6° (range from 27° to 41°). Metaphyseal-diaphyseal angle (MDA) was 16 ± 4° (range from 13° to 24°). The femoral vara angle was 10 ± 4° (range from 2° to 23°). According to Langenskiold's classification, 3 patients were in stage II, 7 patients in stage III, and 2 patients in stage IV. Five cases were affected bilateral and 2 unilaterally, treated by famur, tibia and fibula valgus osteotomies, and a hip spica cast were used for 6 weeks after operation. Results indicated that all patients were followed up 3 to 16 years. FTA, MDA and femur diaphysis were measured, FTA was 2 ± 7°valgus (from 4° vara to 13° valgus). MDA was 1 ± 2°valgus (range from 0° to 12°). Femoral diaphyseal angle was 1 ± 3°valgus (range from 3° vara to 7° valgus). Six patients could walk without any knee pain, except for 1 patient with bilateral disorder feels his left genu uncomfortable after long time stand or work. His MDA was 12°, and FAT was -4°. In conclusion, femur, tibia and fibula osteotomies are useful for correction of Blount's disease. Recurrence and complication are less than those reported for Blount's disease.
布朗特氏病是一种罕见的胫骨近端后内侧骨骺疾病。布朗特描述了婴儿型和青少年型。本研究旨在描述使用股骨、胫骨和腓骨截骨术治疗婴儿型布朗特氏病。1992年5月至2005年5月，纳入7例布朗特氏病患者（3例男性，4例女性），年龄在17至62个月之间。股胫角（FTA）为31±6°（范围为27°至41°）。干骺端-骨干角（MDA）为16±4°（范围为13°至24°）。股骨内翻角为10±4°（范围为2°至23°）。根据兰根斯基尔德分类，3例为Ⅱ期，7例为Ⅲ期，2例为Ⅳ期。5例为双侧受累，2例为单侧受累，采用股骨、胫骨和腓骨外翻截骨术治疗，术后使用髋人字石膏固定6周。结果表明，所有患者均随访3至16年。测量了FTA、MDA和股骨干，FTA为外翻2±7°（从内翻4°至外翻13°）。MDA为外翻1±2°（范围为0°至12°）。股骨干角为外翻1±3°（范围为内翻3°至外翻7°）。6例患者行走时无膝关节疼痛，除1例双侧患病患者在长时间站立或工作后感到左膝不适。他的MDA为12°，FTA为-4°。总之，股骨、胫骨和腓骨截骨术对矫正布朗特氏病有效。复发率和并发症低于报道的布朗特氏病。
