Short-stem prostheses with modular necks were implanted using a modified Watson-Jones approach in 55 cases from November 2004 to May 2006. Twenty-eight cases were navigated using the OrthoPilot navigation system (B. Braun Aesculap, Tuttlingen, Germany). Primary stability, ease of minimal invasive implantation, and restoration of the biomechanics were evaluated. Short-term results showed a good functional outcome and a low complication rate without any dislocations. Apart from cup navigation, the navigation system helps to restore biomechanics in terms of center of rotation, leg length, and offset by advising surgeons on the modular neck offering best fit predicting the safe range of motion (ROM) reliably.
2004年11月至2006年5月期间，采用改良的沃森-琼斯方法，为55例患者植入了带模块化颈的短柄假体。其中28例使用了OrthoPilot导航系统（德国图特林根市贝朗蛇牌）进行导航。对初次稳定性、微创植入的简易性以及生物力学恢复情况进行了评估。短期结果显示功能预后良好，并发症发生率低，无任何脱位情况。除髋臼杯导航外，该导航系统通过为外科医生提供关于最佳适配模块化颈的建议，在旋转中心、腿长和偏移方面有助于恢复生物力学，可靠地预测安全活动范围（ROM）。
