Combination of Evans calcaneal osteotomy and STA-Peg arthroreisis for correction of the severe pes valgo planus deformity.

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.

Mucinous cyst of the sural nerve.

Mucinous cysts are rare neural lesions. There has been no documentation of this lesion affecting the sural nerve. The lesion is referred to by a number of confusing names. The authors present a case history, and propose a new name based on consistent histologic characteristics.

Chevron closing base wedge bunionectomy.

The Chevron-base wedge Association for Osteosynthesis fixated bunionectomy provides a stable, aggressive correction of the severe hallux abducto valgus deformity. It is intended for the bunion requiring a double osteotomy in order to adequately reduce both intermetatarsal and proximal articular facet angle with minimal shortening and elevation. This article presents the rationale for the procedure, technique, and a 4-year follow-up of six patients with eight Chevron-base wedge bunionectomies.
