[Abstract]Fracture of scaphoid bone of wrist are relatively common among upper limb fractures， second only to distal fracture of radius.Due to the uniqueanatomical structure and blood supplyof the scaphoid boneof wrist，it iseasytobecomplicatedwithnonunionandischemicnecrosisafterfracturesoccur，soitisemphasizedto provide timely treatment for patientsthrough earlyandaccurate diagnosis in clinic to minimize theoccurrnceof complications.Atpresent，thediagnosisoffractureof scaphoidboneof wrist ismainlybasedonthecharacteristic manifestations of the fracture site and imaging examinations.However，the duration of characteristic clinical manifestations is short，andthecommonlyusedX-rayexaminationinclinical practicealso hasahigh missed diagnosis rate for fracture of scaphoid bone of wrist.For confirmed scaphorus fractures，the treatment methods include conservative treatment and surgical treatment，inwhich the surgical treatment has the risk of bone mass losing of scaphoid bone of wrist by adjusting the screw position many times.The development and application of computer-assisted technology have provided new ideas for solving the above problems.Therefore，this article makes a reviewbasedonthe research of the application of computer-asisted technologyin the diagnosis and treatment of fracture of scaphoid bone of wrist.

腕舟骨骨折是最常见的腕部骨折之一，多发于青壮年男性，约占腕部骨折的 80% ，是继桡骨远端骨折第二常见的上肢骨折[]。手舟骨由穿过腕舟骨腰部的桡动脉背侧分支负责近端 70%～80% 的血供，桡动脉掌侧分支通过远端结节供应远端 20%～30% 的骨质。这使得腕舟骨近端为逆行性血供，当发生腕舟骨腰部或近端骨折时，此处的血供容易被破坏，进而引起骨折不愈合和缺血性坏死[2]，因此治疗重点往往是如何防治各种并发症。近些年通过计算机辅助技术诊治腕舟骨骨折的研究越来越多，其相较传统技术的优缺点也越来越受到关注。

1计算机辅助技术在腕舟骨骨折诊断中的应用

由于腕舟骨特殊的解剖结构和血运状况，在未得到及时治疗的情况下容易出现骨不连、缺血性坏死等并发症[3]。Langhoff等[4研究指出，在受伤4周后治疗的腕舟骨骨折患者中，骨不连的风险高达 40% ，而在4周内接受治疗，骨不连的风险仅为3% 。可见对于腕舟骨骨折患者来说，早期的精确诊断与及时治疗极为重要。腕舟骨骨折的早期诊断是通过体格检查和影像学检查来实现的。腕舟骨骨折典型体格检查结果包括鼻烟窝部位压痛、腕舟骨结节压痛和拇指纵向受压试验阳性，但这些体征在骨折部位软组织肿胀消退后会被掩盖，往往在损伤后48～72h 变得不显著[5。因此，仅凭临床症状和体征来诊断腕舟骨骨折远远不够，还应该结合影像学检查。

对于腕舟骨骨折的影像检查，目前使用最多的是X线检查，但其存在较高的漏诊率。……
