Flake-Austin modification of the STA-Peg arthroereisis: a retrospective study.
The Smith subtalar arthroereisis implant (STA-peg) is used to correct severe collapsing pes valgoplanus in children. Flake and Austin modified the placement of this implant to block the leading wall of the lateral talus. Twenty-one patients with a total of 40 STA-peg procedures were evaluated subjectively and objectively. The average age at the time of surgery was 9.7 years (4 to 16 years). The follow-up period averaged 36 months (12 to 90 months). The subjective, objective, and radiographic results were positive and the complication rate was low. A significant advantage of the Flake-Austin modification of the STA-peg placement in transverse planar dominant foot types is also noted.
