author believes he achieves a lower incidence of post-tenotomy heel pain using heel elevation. Con- sequently, the majority of the author’s tenotomies are now performed with heel elevation. The author has not appreciated distal interphalangeal joint ar- thritis of major clinical significance with either method. Both forms of derotation shoeing are tech- nically challenging requiring some experience with glue-on technologies. The use of a flat egg bar shoe
following tenotomy was described by Morrison.5 The use of a 5°wedged rail shoe with a heel exten- sion was described by Redden.8 Either type of shoe can be glued to a hoof boot with methylmethacry- lateh,i as discussed previously (Fig. 8). Commercial interchangeable solesc can be used post tenotomy as well. Select and secure either the 5° wedged or flat heel extension (Fig. 1B).
Fig. 7. A, Distal interphalangeal joint subluxation following tenotomy with derotation shoeing. The shoe is a flat egg-bar shoe with a heel plate. B, The same foot as pictured in panel A was switched to a 5° rail shoe with a heel extension due to heel pain 8 weeks later. Notice the improvement in distal interphalangeal joint subluxation provided by heel elevation.
