In order to ensure the bioBLOCK™ provides adequate
support and correction,
we recommend that the bioBLOCK™ implant not be
used in patients weighing
more than 250 pounds. Exceeding this weight guideline
may cause the shape
of the implant to change, resulting in deformation of
the implant shape. The
implant may still provide support and correction in
this altered state, however
it is not recommended.
Make a 1-3cm incision over the sinus tarsi along
the relaxed skin tension lines (Figure 1)
The intermediate dorsal cutaneous nerves should
course superior to the incision
The sural nerve should course inferior to the
incision
Incise the deep fascia
The anterior lateral edge of the posterior facet
of the calcaneus should be palpable with instrumentation
upon completing the dissection into the tarsal
canal (Figure 2)
