A 1st MTP (metatarsophalangeal ) joint fusion  is a highly versatile operation both in terms of the conditions which can be treated as well as in terms of the function possible after successful fusion.

A union rate of 90% plus is recorded in most series using current techniques. Success defined in terms of patient satisfaction rates though can be slightly lower than those of radiographic union of the fusion .

The keys to operative success are careful joint preparation , positioning and appropriate fixation.

There are various ways of fixing the fusion , most commonly  a single axial compressive screw combined with  a dorsal neutralising or compression plate . The technique detailed in this operation is a “crossed-screws” technique which differs only in the final mode of fixation.
