- coleman block test evaluates hindfoot flexibility and pronation of forefoot;
- initial deformity is in the forefoot followed by subsequent changes in the hindfoot;
- test is performed by placing the patient's foot on wood block, 2.5 to 4 cm thick, with the heel and lateral border of foot on the block and bearing full weight while the first, second, & 3rd metatarsals are allowed to hang freely into plantar flexion and pronation;
- test is based on premise that there is fixed flexion of 1st metatarsal;
- this test negates effect that forefoot (first metatarsal in plantar flexion) may have on the hindfoot in stance;
- if heel varus corrects while the patient is standing on the block, hindfoot is considered flexible;
- if subtalar joint is supple & correct w/ block test, then surgical procedures may be directed to correcting forefoot pronation, which is usually due to plantar flexion of 1st metatarsal;
- if hindfoot is rigid, then surgical correction of both forefoot & hindfoot are required
