Corticosteroid Injections in Posterior Ankle Impingement Syndrome: A Survey of Professional and Elite Student Ballet Dancers.

J Dance Med Sci 2021 Mar;25(1):24-29

Orthopaedic Research Center Amsterdam (ORCA), Department of Orthopedic Surgery, Amsterdam UMC, University of Amsterdam; Academic Center for Evidence Based Sports Medicine (ACES); Amsterdam Collaboration for Health and Safety in Sports (ACHSS), Amsterdam, the Netherlands; FIFA Medical Centre of excellence Ripoll-dePrado-vanDijk SportClinic Madrid, Spain; and FIFA Medical Centre of Excellence Clinica do Dragao Porto, Portugal.

Posterior ankle impingement syndrome (PAIS) involves pain at the posterior as- pect of the ankle, due in dancers largely to repetitive hyperplantarflexion. In daily practice, corticosteroid injection is often used to relieve the pain of PAIS, but little has been recorded with regard to its effectiveness. The primary objective of this study was to determine the ef- fect on pain of corticosteroid injections in professional and elite student ballet dancers with PAIS. Read More

Infinity ankle arthroplasty with traditional instrumentation and PSI prophecy system: preliminary results.

Acta Biomed 2020 12 30;91(14-S):e2020021. Epub 2020 Dec 30.

Department of Orthopaedic Surgery, S. Maria della Misericordia Hospital, Rovereto, Italy.

Ankle arthrodesis has been considered the surgical Gold Standard for advanced ankle arthritis; prosthetic replacement of the tibio-talar joint played a secondary role.The introduction of last generation ankle prostheses lead to better outcome and a lower rate of complication. PSI represents the most recent innovations introduced on the market of ankle arthroplasty:PSI is proposed as a surgical technique capable of making ankle arthroplasty more accurate and more reproducible compared to standard referencing guides Aim of the study is to report early clinical and radiographic outcomes obtained from a single surgeon experience by implanting the same ankle prosthesis using a standard (STD) or a PSI instrumentation Unlike no difference in the average increment of normalized sub score related to function in each group (PSI vs STD), the analysis of normalized pain sub score pointed out a greater average improvement in the PSI group(+75%)compared to the STD group(+62%);this result has been adovacated to the absence of post operative gutter impingement syndrome in the PSI group compared to the STD referencing group.

JBJS Case Connect 2020 Jul-Sep;10(3):e2000080

1Department of Pediatric Orthopedics and Adult Foot and Ankle Surgery, Orthopedic Hospital Speising, Vienna, Austria.

Case: Two adolescent patients with therapy-refractory ulnocarpal wrist pain because of mild ulnar longitudinal deficiency (ULD; ulna hypoplasia type I according to Bayne) underwent surgical treatment with a Z-shaped ulna lengthening osteotomy and interposition of the iliac crest bone graft. Long-term ULD correction and pain-free motion were maintained in both patients.

Accessory Anterolateral Talar Facet Syndrome After Treatment of Neglected Fracture of the Lateral Process of the Talus: A Case Report.

J Foot Ankle Surg 2020 Jul - Aug;59(4):826-828. Epub 2020 Jan 22.

Professor, Department of Orthopaedic Surgery, Nara Medical University, Kashiharashi, Nara, Japan.

Fracture of the lateral process of the talus has often been missed or confused with lateral ankle sprain, and this can lead to long-term untreated cases of nonunion, malunion, and subtalar joint osteoarthritis. In a review of the published data, accessory anterolateral talar facet syndrome was not found after treatment of nonunion of the lateral process of the talus fracture. This report presents the case of a 40-year-old male snowboard instructor who suffered from a neglected fracture of the lateral process of the talus and was treated with open reduction using an iliac autogenous bone graft.

Surg Radiol Anat 2020 Jun 6;42(6):691-693. Epub 2020 Jan 6.

Department of Anatomy, School of Life Dentistry at Niigata, Nippon Dental University, Niigata, Japan.

Purpose: The deep component of the posterior inferior tibiofibular ligament (PITFL) was classified by type in this large-scale cadaveric study to provide basic information that will help elucidate the mechanisms underlying ankle joint posterior impingement syndrome.
