Posterior Ankle Impingement Caused by Hyaline-Like Cartilage Generation in Ballet Dancers-A Report of 2 Cases.

J Foot Ankle Surg 2022 Jul-Aug;61(4):e9-e14. Epub 2021 Oct 22.

Department of Orthopaedic Sports Medicine, Osaka Rosai Hospital, Sakai, Osaka, Japan.

Posterior ankle impingement syndrome is mainly seen in ballet dancers and frequently associated with specific movements in ballet such as pointe and demi pointe in which the whole-body weight is applied to the maximally plantar flexed ankle. We performed arthroscopic debridement for 2 dedicated ballet dancers on the intervening soft tissue causing posterior ankle impingement syndrome (PAIS). In both cases, T2-weighted magnetic resonance imaging (MRI) revealed low-signal intensity of meniscus-like soft tissue without abnormal osseous findings, connecting from the posterior side of the talus to Kager's fat pad.

Chronic Fracture of the Posteromedial Tubercle of the Talus Masquerading as Os Trigonum Syndrome.

Case Rep Orthop 2021 28;2021:6637081. Epub 2021 Jun 28.

Guy's & St Thomas' Hospital, London, UK.

Posterior ankle impingement syndrome (PAIS) can be caused by osseous pathology from the posterior aspect of the talus. The commonest cause is an os trigonum, an accessory ossicle arising from the tubercle of the posterior talus. We have observed cases where the osseous impingement is due to a chronic fracture nonunion of the tubercle of the posterior talus with unique symptoms, differentiating this clinical syndrome from the more common os trigonum syndrome.

MRI of lateral hindfoot impingement.

Darshana Sanghvi

Diagn Interv Radiol 2021 May;27(3):432-439

Lateral hindfoot impingement (LHI) is a subtype of ankle impingement syndrome with classic MRI findings. Biomechanically, LHI is the sequela of lateral transfer of weight bearing from the central talar dome to the lateral talus and fibula. The transfer occurs due to collapse of the medial arch of the foot, most commonly from posterior tibial tendon (PTT) and spring ligament (SL) insufficiency. Read More

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.
