BACKGROUND AND PURPOSE The evaluation of metaphyseal angular deformities in children includes indication and timing for corrective osteotomy, and possible need for several operations during growth. Gap-fillers are usually autologous bone grafts, which might cause donor site problems. Calcium phosphate (CaP) bone cement may be a possible alternative. PATIENTS AND METHODS We performed 15 corrective osteotomies from 2007 to 2013 in 10 children, ages 5 to 18, with Norian SRS bone cement as a gap-filler, in the distal radius (12), proximal radius (1), and proximal humerus (2). Due to growth arrest and gradually increasing malalignments 3/10 children needed 1-3 additional corrections. Locking plates and screws were used except in 1 case at first surgery, aged 5 (K-wires). 2 children needed additional limb lengthening with external fixator. RESULTS All osteotomies healed. Postoperative radiographs and CT scans showed good alignment and gradual transformation of cement into bone. Remodeling was visible intraoperatively in patients needing multiple surgeries. Return to earlier osteotomy sites was unproblematic. No adverse events from using CaP cement were experienced. INTERPRETATION CaP cement is an alternative to bone grafts in upper extremity metaphyseal corrective osteotomies in children, and also when greater corrections are necessary or several surgeries indicated during the growth period.

上肢磷酸钙骨水泥和干骺端矫正截骨术：10名儿童的长期随访。


背景和目的儿童干骺端角度畸形的评估包括矫正截骨术的指征和时机，以及生长期间可能需要进行的多次手术。间隙填充物通常是自体骨移植物，这可能会导致供体部位问题。磷酸钙（CaP）骨水泥可能是一种可能的替代品。患者和方法 2007 年至 2013 年，我们对 10 名 5 至 18 岁的儿童进行了 15 次矫正截骨术，使用 Norian SRS 骨水泥作为间隙填充物，分别在桡骨远端 (12)、桡骨近端 (1) 和肱骨近端 (1) 2）。由于生长停滞和逐渐增加的畸形，3/10 的儿童需要 1-3 次额外矫正。除 1 例首次手术时使用锁定板和螺钉外，该病例年龄为 5 岁（克氏针）。 2 名儿童需要使用外固定器进行额外的肢体延长。结果 所有截骨均愈合。术后X光片和CT扫描显示骨水泥排列良好，并且骨水泥逐渐转变为骨。需要多次手术的患者在术中可以看到重塑。返回先前的截骨部位是没有问题的。使用 CaP 水泥未出现任何不良事件。解释 Cap 骨水泥是儿童上肢干骺端矫正截骨术中骨移植的替代方案，也适用于需要进行更大程度的矫正或在生长期需要进行多次手术的情况。
