Silverman examined macrodystrophia histologically and found an association between macrodactyly and abnormalities of the median and
plantar nerves (5).
Mourougayan [13] advocates the use of the medial plantar artery instep flap as it can be raised as an island fasciocutaneous flap based on medial plantar vessels, with the branch of the medial
plantar nerve supplying the instep skin and reaching the posterior-most part of the weightbearing surface of the heel with ease.
The characteristic feature of the condition is that the anatomical location of the abnormality corresponds closely with the zone of innervation by the sclerotome.1 Involvement of the 2nd and 3rd digits of the hands and feet is common, corresponding to the median and the medial
plantar nerve supply in the upper and lower limbs respectively; but 5th digit involvement is rare.
The medial
plantar nerve branches can get entrapped between the knot of Henry and the abductor hallucis muscle, leading to first and second toe plantar dysesthesias.
The cerclage wire is pulled epiperiosteally to the plantar aspect of the calcaneus to avoid damage to local soft tissues, such as plantar fascia and lateral
plantar nerve (Figure 1(d)).

* Compression of the first branch of the lateral
plantar nerve.
This congenital abnormality occurs most frequently in the distribution of the median nerve in the upper and medial
plantar nerve in the lower extremity.
Medial calcaneal branches from the lateral
plantar nerve. Rev.
(2), (4), (5) It is typically described in a particular nerve distribution; usually the medial
plantar nerve or median nerve.
Inside this canal, each muscular body originates a small tendon that crosses by its deep surface the lateral
plantar nerve and corresponding vessels.
