In hand and spinal surgery nerve lesions are feared complications with the use of standard oscillating saws. Oral surgeons have started using a newly developed ultrasound bone scalpel when performing precise osteotomies. By using a frequency of 25-29 kHz only mineralized tissue is cut, sparing the soft tissue. This reduces the risk of nerve lesions. As there is a lack of experience with this technique in the field of orthopaedic bone surgery, we performed the first ultrasound osteotomy in hand surgery.
While performing a correctional osteotomy of the 5th metacarpal bone we used the Piezosurgery Device from Mectron [Italy] instead of the usual oscillating saw. We will report on our experience with one case, with a follow up time of one year.
The cut was highly precise and there were no vibrations of the bone. The time needed for the operation was slightly longer than the time needed while using the usual saw. Bone healing was good and at no point were there any neurovascular disturbances.
The Piezosurgery Device is useful for small long bone osteotomies. Using the fine tip enables curved cutting and provides an opportunity for new osteotomy techniques. As the device selectively cuts bone we feel that this device has great potential in the field of hand- and spinal surgery.
在手部和脊柱手术中，使用标准摆动锯时神经损伤是令人担忧的并发症。口腔外科医生在进行精确截骨术时已开始使用新开发的超声骨刀。通过使用25 - 29千赫兹的频率，仅切割矿化组织，软组织得以保留。这降低了神经损伤的风险。由于在骨科骨手术领域缺乏对该技术的经验，我们在手部手术中进行了首例超声截骨术。
在对第五掌骨进行矫正截骨术时，我们使用了意大利美创公司的超声骨刀设备，而非通常的摆动锯。我们将报告一例病例的经验，随访时间为一年。
截骨非常精确，且骨骼无振动。手术所需时间略长于使用普通锯时所需的时间。骨愈合良好，且在任何时候都没有出现神经血管干扰。
超声骨刀设备适用于小型长骨截骨术。使用精细刀头可进行曲线切割，并为新的截骨技术提供了机会。由于该设备能选择性地切割骨骼，我们认为该设备在手部和脊柱手术领域具有巨大潜力。
