[Treatment of ankle osteoarthritis : Analysis of a German nationwide survey].

Klinik für Orthopädie, Unfallchirurgie und Sporttraumatologie Köln Merheim, Köln, Deutschland.

Background: In most cases osteoarthritis of the ankle is of posttraumatic origin. Younger people are more frequently affected, which makes treatment a particular challenge. In addition to conservative treatment numerous surgical procedures are available for the treatment of advanced arthrosis.

Background: The aim of this study was to investigate the clinical and radiologic outcomes following supramalleolar osteotomy for early varus ankle arthritis with the medial translation of the talus, wherein the lateral translation of the talus center to the tibial axis was used as a correction target. Another aim was to compare the results between the ankles with a normal range of medial distal tibial angle (MDTA) and overcorrected MDTA at the postoperative period to investigate the role of overcorrected MDTA after the supramalleolar osteotomy.

Methods: The study comprised 90 patients (93 ankles) with Takakura stage 2 or 3a varus ankle arthritis with the medial translation of the talus, which underwent medial opening supramalleolar osteotomy with fibular osteotomy, and the mean duration of follow-up was 50.

Supramalleolar osteotomy (SMO) aims to correct extra-articular deformities of the distal lower leg. There are several indications, the most common being varus osteoarthritis of the ankle. The rationale in this indication is to modify talocrural stress and pressure distribution by reorienting the limb axis.

Although distal tibial oblique osteotomy (DTOO) has usually been indicated for noninflammatory diseases such as osteoarthritis, we encountered three patients with rheumatoid arthritis (RA) who underwent DTOO. We evaluated radiographic parameters and clinical scores, including self-reported scores for the foot and ankle [self-administered foot evaluation questionnaire (SAFE-Q)] and the Japanese Society for Surgery of the Foot (JSSF) ankle/hindfoot scale. In all three cases, radiographic improvements were achieved along with improvements in SAFE-Q and JSSF scores after mid-term follow-up.

Oblique Dorsiflexion Osteotomy of the Distal Tibia for Fixed Ankle Equinus: Surgical Technique.

Strategies Trauma Limb Reconstr

August 2024

Department of Orthopedic Surgery, Phoenix Children's Hospital, Phoenix, Arizona, United States of America.

Aim: There are significant challenges in the treatment of a severe rigid ankle equinus caused by a flat-topped talus, arthrogryposis, burn sequelae, or extensive scarring. Conventional approaches, such as soft tissue releases, often fail due to joint incongruence or compromised soft tissues, thereby necessitating supramalleolar osteotomies. The classic transverse supramalleolar osteotomy (TSO) of the distal tibia can lead to secondary anterior translation of the centre of rotation of the ankle and alters mechanical and anatomical axes.
