There are few reports of Low-intensity pulsed ultrasound (LIPUS) treatment for fresh forearm fractures in children.
LIPUS stimulation was applied after surgery of forearm fractures in children and the efficacy and safety of combination therapy of LIPUS treatment were evaluated.
Children with both radius and ulna fracture, twenty-five diaphysis (mid-R&U) and nineteen metaphysis (dist-R&U) fractures, were treated with intramedullary nailing followed by cast and splint mobilization. Thirteen patients in the mid-R&U fracture group and eight patients in the dist-R&U fracture group were combined with LIPUS stimulation postoperatively.
Periosteal callus appeared significantly earlier after surgery in the LIPUS-treated groups than in the groups without LIPUS treatment. The duration of external fixation was significantly shorter in the dist-R&U fracture group treated with LIPUS stimulation compared with that in the mid-R&U fracture group without LIPUS treatment. Furthermore, the time span needed for bone union in the groups with LIPUS stimulation was significantly shorter than in the groups without LIPUS stimulation.
It is suggested that LIPUS stimulation can lead to a reduction of treatment periods of unstable forearm fractures safely after operation even in children.
关于低强度脉冲超声（LIPUS）治疗儿童新鲜前臂骨折的报道较少。
对儿童前臂骨折术后应用LIPUS刺激，评估LIPUS治疗联合疗法的疗效和安全性。
25例尺桡骨干骨折和19例尺桡骨远端骨折的儿童患者接受髓内钉固定，随后进行石膏和夹板固定。尺桡骨干骨折组13例患者和尺桡骨远端骨折组8例患者术后联合LIPUS刺激。
LIPUS治疗组术后骨膜骨痂出现明显早于未接受LIPUS治疗的组。与未接受LIPUS治疗的尺桡骨干骨折组相比，接受LIPUS刺激的尺桡骨远端骨折组外固定时间明显缩短。此外，接受LIPUS刺激组的骨愈合所需时间明显短于未接受LIPUS刺激的组。
提示LIPUS刺激即使对儿童不稳定前臂骨折术后也能安全地缩短治疗周期。
