The biplanar (Rippstein/Dunlop) technique is commonly used to radiographically determine the neck-shaft and anteversion angles of the hip. This method is unsuitable for certain groups of patients, such as those with fixed contracture of the hip joint. In these patients we have found the 'sinus wave' method to be preferable. We compared the neck shaft and anteversion angles of 30 hips determined by these two methods. Correlation was good for both the neck shaft (r = 0.972) and anteversion angles (0.69). We also used ultrasound to measure the anteversion but this correlated poorly with the Rippstein/Dunlop technique (r = 0.56). We believe that the sound wave technique is an accurate and practical way to determine the anteversion and neck-shaft angles of the hip.
双平面（里普斯坦/邓洛普）技术常用于通过X线摄影确定髋关节的颈干角和前倾角。该方法不适用于某些患者群体，如髋关节固定挛缩的患者。在这些患者中，我们发现“正弦波”方法更可取。我们比较了用这两种方法测定的30个髋关节的颈干角和前倾角。颈干角（r = 0.972）和前倾角（0.69）两者的相关性都很好。我们还使用超声测量前倾角，但它与里普斯坦/邓洛普技术的相关性较差（r = 0.56）。我们认为，声波技术是确定髋关节前倾角和颈干角的一种准确且实用的方法。
