Oper Orthop Traumatol. 2023 Oct 16. doi: 10.1007/s00064-023-00831-9. Online ahead of print.ABSTRACTOBJECTIVE: The aim of this paper is to describe the anterolateral approach using an anatomical plate for ankle arthrodesis and to present the first mid-term results with this technique in a high-risk population.INDICATIONS: The indication for arthrodesis of the ankle joint with this described technique is moderate to severe osteoarthritis of the ankle.CONTRAINDICATIONS: In addition to the general contraindications typical of any operation, there is a specific contraindication in cases of active infection of the soft tissues and accompanying osteomyelitis at the ankle.SURGICAL TECHNIQUE: The incision is made along the course of the peroneus tertius muscle. After that, the mobilization of the peroneus superficialis nerve is carried out, followed by the mobilization of the long extensor tendons, especially the extensor digitorum muscle in a medial direction opening the capsule and removal of the residual cartilage on the distal tibia and talus. Subsequently, the subchondral sclerosis is opened, and the implantation of a suitable osteosynthesis material, e.g., an anatomical angle-stable plate, is carried out. Finally, wound closure is performed involving the muscle belly of the extensor digitorum muscle covering the plate.POSTOPERATIVE MANAGEMENT: Immobilization of the ankle for 5-7 days in a dorsal knee-high splint. Retention in a walker after decongestion for another 5 weeks. Incr...
