Saddle Bone Deformity

After a visit to ‘Google Doctor’ (Google should really make a Google Doctor sections along with Google Search, Google Maps etc), it seems I have a foot injury called Saddle Bone on my right foot.

Entrapment of the deep peroneal nerve is another common peripheral nerve entrapment of the foot. The deep peroneal nerve is found on the top of the foot (anterior or dorsal foot). A deep peroneal nerve entrapment is often found in conjunction with a small bump of bone at the metatarsal cuneiform joint. This bump of bone is called a saddle bone deformity or met-cuneiform exostosis. A deep peroneal nerve entrapment is an entrapment of the nerve as it descends over the top of the Tinel's_sign_anterior_tarsal_tunnel_syndromesaddle bone deformity. Compression of the deep peroneal nerve occurs when we wear shoes that apply pressure to the saddle bone deformity. The result is that the deep peroneal nerve is compressed between the shoe and bone. We’ll often see a deep peroneal nerve entrapment in skiers, those who wear clogs or folks who lace their shoe very tightly. In each case, the direct pressure from the shoe compresses the nerve over the bump of bone. A Tinel’s sign can be elicited at the top of the foot with a positive Tinel’s sign resulting in electrical shock sensation to the first and second toes.

Recently when running, I have been putting a bandage on my foot which eased the pain, however, really this should have been putting more pressure on the nerve.

Lacing shoes differently so that the laces do not cross over the area where the bone is enlarged and instead runs up the side to the next eyelid seems like one of the solutions to ease the pressure, so I have laced up my trainer like this to see how things work out.

Surgery is the ultimate solution, with 6-8 weeks recovery, but I will obviously be avoiding that for as long as possible.

 

An update 4 weeks after this post:-

Using the lacing method as shown above, where the laces do not cross over the raised bone area, I have suffered no pain what-so-ever on any of my runs since. Therefore I would certainly recommend trying this before exploring other options.
