Interphalangeal joint arthrodesis with oblique placement of an AO lag screw.
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.
