A damaged interphalangeal (IP) joint may be treated by fusion. Arthrodesis should leave the joint at the most functional angle and give sound bony union in the shortest possible time, maintaining maximum proximal and distal joint motion. The lateral oblique placement of a single AO lag screw, proximal to distal, achieves these aims. This method gives sufficient proximal bone for screw purchase and better control of the desired angle of fusion. This technique has led to fusion in 22 of 23 joints (96%), taking an average of 8.2 weeks.
受损的指间关节（IP）可通过融合术进行治疗。关节固定术应使关节处于最具功能的角度，并在尽可能短的时间内实现稳固的骨愈合，同时保持近端和远端关节的最大活动度。由近端至远端单枚AO拉力螺钉的外侧斜向置入可实现这些目标。该方法为螺钉固定提供了足够的近端骨质，并能更好地控制所需的融合角度。采用此技术，23个关节中有22个（96%）实现了融合，平均用时8.2周。
