- See: 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;
