    • A leg length gauge for use during hip joint replacement surgery to insure that the overall length of the patient's leg subsequent to the surgery is substantially the same as it was prior to the surgery. A first pin is inserted into a patient's ilium and a second pin is inserted into the patient's femur. A removable gauge including an adjustably coupled pair of members having pin receiving apertures for receiving the first and second pins is positioned on the pins. One member includes a base portion provided with one of said pin receiving apertures and having an elongated leg extending from the base portion. The other member is provided with the other pin receiving aperture and includes a transverse aperture for receiving the elongated leg. The elongated leg is selectively adjustably secured within the transverse aperture by tightening a thumbscrew. When properly oriented, the first pin extends generally vertically from the ilium, the second pin extends generally vertically from the femur and the elongated leg extends generally horizontally between the base portion and the other member.
    • 用于髋关节置换手术期间的腿部长度计,以确保手术后患者腿部的总长度与手术前基本相同。 将第一针插入患者的髂骨中,将第二针插入患者的股骨。 包括可调节地耦合的一对构件的可拆卸的量具具有用于接收第一和第二销的销接收孔定位在销上。 一个构件包括设置有所述销接收孔中的一个并具有从基部延伸的细长腿的基部。 另一个构件设置有另一个销接收孔,并且包括用于接收细长腿的横向孔。 通过拧紧指旋螺钉,细长的腿可选择性地可调节地固定在横向孔内。 当适当定向时,第一销大致垂直地从髂骨延伸,第二销大体上垂直于股骨延伸,并且细长腿在基部和另一个构件之间大致水平地延伸。
