The beginnings of osteosynthesis (OS) in the Czech lands, dating back to the second half of the 19th century, are associated with the German surgeons W. Heine and C. Gussenbauer working in Prague. Development of the Czech musculoskeletal surgery began with the appointment of K. Maydl to the head of the Czech University Department of Surgery in Prague in 1891. In 1908, his pupil K. Kukula published the first "OS manifesto" in the Czech literature, including his own original method of fixation of diaphyseal fractures with a magnezium peg. Further development of OS of fractures came as late as in the 1920s. The first to publish his own results in a cohort...

NURI KORAY ÜLGEN, BATUHAN GENCER, TEOMAN BEKIR YENI, ÖZGÜR DOĞAN

Acta Chir Orthop Traumatol Cech. 2025; 92(2):114-117 | DOI: 10.55095/achot2025/001  

Isolated subtalar dislocations constitute 1% of all dislocations and are extremely rare. They frequently occur as a result of high-energy trauma. Dislocations are classified based on the direction of the dislocation, with 80% being medial. Closed reduction under anesthesia without delay is the optimal treatment method. In our case, we present an extremely rare instance of an isolated lateral subtalar dislocation resulting from a low-energy injury. Although isolated subtalar dislocations are frequently reduced with closed reduction, open reduction was necessary in our case. The structure obstructing reduction in lateral dislocations is often reported...
