Abstract

We describe a method for planning total hip arthroplasty (THA) in patients with a displaced femoral neck fracture based on a simple CT scan protocol of the contralateral hip. This protocol was used on 22 consecutive patients during the inclusion period, followed by reconstruction and 2D templating to predict the implant size and positioning. The exact planned size was achieved in 21/22 (95%) cups, 14/22 (64%) femoral stems and 14/22 (64%) femoral heads. There were no intra- or postoperative fractures. After surgery in which this planning method had been applied, the differences in length and lateral offset were less than 5 mm on average relative to the opposite side (mean postoperative leg length difference of −2 mm (−8 to +3 mm) and lateralization of −4 mm (−14 to +3 mm)). While this technique exposes the patient to additional radiation, it does not require any specific devices or surgical approach and could be used in most hospitals.

用于股骨颈骨折患者全髋关节置换术规划的简易 CT 扫描方案。

我们介绍了一种根据对侧髋关节的简单 CT 扫描方案为股骨颈骨折移位患者规划全髋关节置换术（THA）的方法。在纳入期间，该方案连续应用于 22 例患者，随后通过重建和二维模板来预测植入物的大小和位置。21/22（95%）例髋臼杯、14/22（64%）例股骨柄和14/22（64%）例股骨头均准确达到了计划尺寸。术中和术后均未发生骨折。采用这种规划方法进行手术后，相对于对侧，长度和侧偏差平均小于5毫米（术后平均腿长差为-2毫米（-8至+3毫米），侧偏差为-4毫米（-14至+3毫米））。虽然这种技术会使患者受到额外的辐射，但它不需要任何特殊的设备或手术方法，可在大多数医院使用。证据等级：四级。
