title: Combination of Evans calcaneal osteotomy and STA-Peg arthroreisis for correction of the severe pes valgo planus deformity.
abstract: Twenty patients with 25 symptomatic severe flexible pes valgo planus were treated with a combined surgical technique. All patients underwent an Evans calcaneal osteotomy with allogenic bone graft and subtalar joint arthroreisis (STA-Peg) procedure. Adjunctive procedures as deemed necessary included Achilles tendon lengthening, navicular-cuneiform fusion, Lapidus first metatarsal cuneiform fusion, Cotton medial cuneiform plantarflexory wedge osteotomy with allogenic bone graft, plantarflexory medial cuneiform osteotomy, and excision of os tibiale externum. A retrospective pre- and postoperative radiographic evaluation revealed the following mean changes: lateral talo-first metatarsal angle, 16.9 degrees to -0.6 degrees; calcaneal cuboid abduction angle, 24.8 degrees-2.8 degrees; anterior posterior talocalcaneal angle, 25.3 degrees-15.4 degrees; talonavicular coverage angle, 22.7 degrees-5.2 degrees; calcaneal inclination angle, 10.6 degrees-18.6 degrees; talar declination angle, 32.4 degrees-16.4 degrees; lateral talocalcaneal angle, 18.3 degrees-5.2 degrees. A subjective questionnaire revealed that 100% of the patients stated they were satisfied or very satisfied with the surgery and achieved an average score of 93 based on a 100-point scale.
