The effectiveness of navigation systems in performing accurate orthopaedic surgery has been reported previously, but there have been no reports on the application of navigation in surgeries involving bone resection around the elbow joint. In this study, anatomical plasty or bone resection was performed to restore anatomical morphology in 10 cases of osteoarthritis of the elbow and deformity of the distal end of the humerus. Bone resection was performed on the distal end of the humerus using navigation and on the proximal end of the ulna via freehand surgery. Postoperatively, the elbow function was evaluated and pre- and postoperative CT images were used to measure the bone resection. There were no complications arising from the use of navigation, and elbow function was improved in all cases. By evaluating the CT images, it was found that navigated resection of the fossae of the distal humerus was more effective than freehand resection of the processes of the proximal ulna, thus confirming the usefulness of navigation. In future, to fully confirm this finding, it will be necessary to conduct prospective controlled studies of cases in which navigation is used to perform arthroplasty, including those that involve the proximal end of the ulna.
导航系统在进行精确骨科手术中的有效性此前已有报道，但尚无关于导航在肘关节周围骨切除手术中应用的报道。在本研究中，对10例肘关节骨关节炎和肱骨远端畸形患者进行了解剖复位或骨切除以恢复解剖形态。使用导航对肱骨远端进行骨切除，对尺骨近端进行徒手手术。术后评估肘关节功能，并使用术前和术后CT图像测量骨切除情况。使用导航未出现并发症，所有病例的肘关节功能均得到改善。通过评估CT图像发现，导航下肱骨远端窝切除比尺骨近端突的徒手切除更有效，从而证实了导航的实用性。未来，为充分证实这一发现，有必要对使用导航进行关节置换术的病例，包括涉及尺骨近端的病例，进行前瞻性对照研究。
