Position of Subtalar Fusion:
- Discussion:
- knee deformities should be corrected prior to any forefoot fusions;
- varus hindfoot may have compensatory forefoot valgus w/ plantarflexed 1st ray;
- look for cavus type deformity
-
hammer toes may also be present;
- observing pt's
gait may reveal dynamic hammer toe formation
in the cavus type of foot;
- determine
flexibility of forefoot & hindfoot;
- if foot can be reduced to satisfactory position then subtalar fusion is enough;
- if hindfoot deformity is fixed and cannot be brought into satisfactory position,
a
Triple Arthrodesis may be necessary;
- valgus hindfoot may be associated w/ varus forefoot deformity
along with an abducted forefoot via hindfoot joint;
- look for Achilles tendon contracture w/ pronated deformity of the foot;
- accurate appraisal of contracted tendon may be difficult w/ fixed valgus
deformity which prevents placement of hindfoot in varus;
