Brief Summary

There is no consensus on the surgical treatment of unremitting, painful flatfeet in children. Subtalar arthroereisis has gained notoriety although there is a paucity of literature on its biomechanical effects. The goal of the investigators was to compare a group treated with subtalar arthroereisis with another group undergoing lateral column calcaneal lengthening. The investigators hypothesis was that the results of arthroereisis would be equivalent to the more established method of calcaneal lengthening.

Painful flatfeet; Planovagus feet; Subtalar arthroeresis; Lateral column lengthening; Kinematic motion analysis

Outcome Measures

Primary Outcomes (1)

• Kinematics motion analysis

  The change in hindfoot angle, degree of hindfoot mobility both pre- and postoperatively, degree of ankle motion both pre- and postoperatively, and amount of flexion occurring between the forefoot and hindfoot both pre- and postoperatively.

Eligibility Criteria

• Age: 7 Years - 17 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17)
• Sampling Method: Non-Probability Sample

Study Population

Patient ages ranged from 7 to 17 (mean 12.8y) at the time of surgery. Inclusion criteria were patients with planovalgus deformity, painful symptoms refractory to conservative treatment for at least 6 months, and independent ambulation without the use of assistive devices. A longitudinally study of two patient cohorts: 1) children with planovalgus foot deformity treated with arthroereisis (subtalar implant) and 2) children with planovalgus foot deformity treated by calcaneal (lateral column) lengthening.

You may qualify if:

• Planovalgus foot deformity
• Patient normally ambulates without use of assistive devices
• Patient is between the ages of 7 and 17 at the initial evaluation

You may not qualify if:

• Hip flexion contractures greater than 15 deg.
• Knee flexion contractures greater than 10 deg.
• Ankle dorsiflexion less than 0 deg. (plantarflexion contracture)
• Taking medication which effects motor control
• Inability to follow instructions to perform study
