Fourteen fractures (8 open, 6 closed) were treated with small-diameter interlocking tibial nails and observed for at least 1 year. Radiographs were obtained to monitor the maintenance of reduction and fracture healing. The treating orthopaedic surgeon was blinded to the results of ultrasound studies, which were obtained at 2-week intervals for 10 weeks postoperatively and read by a radiologist who was blinded to the clinical and radiographic progress. Ultrasound correctly predicted fracture healing in all 9 fractures that subsequently progressed to fracture union. Of the 5 fractures that did not heal and required secondary procedures, ultrasound predicted delayed healing in 4 fractures. Overall, ultrasound was able to predict fracture healing before it was radiographically evident. Ultrasound may provide important prognostic information concerning tibial fracture healing after treatment using interlocking nails without reaming. Additional study is warranted.
14例骨折（8例开放性骨折，6例闭合性骨折）采用小直径带锁胫骨髓内钉治疗，并随访至少1年。通过X线片监测骨折复位及愈合情况。治疗的骨科医生对超声检查结果不知情，超声检查在术后10周内每2周进行1次，由对临床和X线进展不知情的放射科医生解读。超声正确预测了所有9例随后达到骨折愈合的骨折的愈合情况。在5例未愈合且需要二次手术的骨折中，超声预测了4例骨折愈合延迟。总体而言，超声能够在X线显示骨折愈合之前预测骨折愈合情况。超声可能为使用非扩髓带锁髓内钉治疗后的胫骨骨折愈合提供重要的预后信息。有必要进行进一步研究。
