Limb length discrepancy and deformities resulting from Ollier’s disease are challenging to treat and have increased complications. We aimed to assess the safety of intralesional osteotomy for distraction osteogenesis and report the results of guided growth as a method of deformity correction in such conditions. We retrospectively reviewed 13 patients (eight boys and five girls), 28 segments (12 femora and 16 tibias), treated using Ilizarov circular ring fixator in one center. Nine patients had an oblique plane deformity, whereas four had a coronal plane deformity. Femoral shortening ranged from three to 11 cm. Tibial shortening ranged from 3.5 to 12 cm. Intralesional osteotomy was carried out in all patients, and guided growth (hemiepiphysiodesis) was used in seven segments (25%). The median age was 11 years (6–14 years) at surgery, with a median follow-up of 4.5 years (3–18 years). The median achieved lengthening in the femur was 7 cm (5–11 cm) and in the tibia was 5 cm (3–9 cm). The average Bone Healing Index (BHI) for the femur was 32 days/cm (28–38 days/cm), and for the tibia was 36 days/cm (28–40 days/cm). Before frame removal, the mechanical axis was restored to the knee joint center in all cases. Normal radiographic bone regeneration was evident in all cases. Hemiepiphysiodesis successfully corrected the angular deformities. Intralesional osteotomy for distraction osteogenesis is well-tolerated and reliable in Ollier’s disease. Radiological normal bone was formed at the distraction site. Guided growth is also a reproducible method for deformity correction in Ollier’s disease, similar to other conditions.

奥利尔氏病导致的肢体长度差异和畸形很难治疗，并且会增加并发症。我们的目的是评估病灶内截骨术用于牵引成骨的安全性，并报告引导生长作为此类情况下畸形矫正方法的结果。我们回顾性审查了 13 名患者（8 名男孩和 5 名女孩），28 个节段（12 股骨和 16 胫骨），在一个中心使用 Ilizarov 圆环固定器进行治疗。九名患者患有斜面畸形，四名患者患有冠状面畸形。股骨缩短3至11厘米。胫骨缩短范围为 3.5 至 12 厘米。所有患者均进行病灶内截骨术，并在七个节段（25%）中使用引导生长（半骨骺固定术）。手术时中位年龄为 11 岁（6-14 岁），中位随访时间为 4.5 年（3-18 岁）。股骨延长的中位数为 7 厘米（5-11 厘米），胫骨延长的中位数为 5 厘米（3-9 厘米）。股骨的平均骨愈合指数 (BHI) 为 32 天/厘米（28-38 天/厘米），胫骨为 36 天/厘米（28-40 天/厘米）。在拆除框架之前，所有情况下机械轴均恢复至膝关节中心。在所有病例中，放射线照相骨再生均明显正常。半骨骺固定术成功矫正了角度畸形。用于牵引成骨的病灶内截骨术在奥利尔病中具有良好的耐受性和可靠性。在牵引部位形成放射学正常骨。与其他疾病类似，引导生长也是奥利尔病畸形矫正的一种可重复的方法。
