Background: Chondrosarcomas (CS) are a rare and heterogenic group of primary malignant bone tumors. In the literature, data on prognostic factors in chondrosarcomas are scarce, and most studies are limited by a short follow-up. The aim of this retrospective study was therefore to determine factors associated with the survival and local recurrence of chondrosarcomas and to compare the results with previous studies.

- This study analyzes the distribution and types of benign and malignant lesions in the hindfoot and ankle over a 12.5-year period, showing that the majority of cases (81.9%) were soft tissue lesions, with a smaller portion being osseous lesions (18.1%).
- Of the reviewed cases, 77 were benign and 9 were malignant, leading to an overall malignancy rate of 8.6%, with malignant cases seen primarily in older patients (mean age of 59.2 years).
- The findings emphasize the importance of accurate imaging and pathology assessment, as benign lesions are more common but malignant tumors can present similarly and should be taken seriously, especially in ambiguous cases
Article Synopsis
- * Of the tumors studied, 51.7% involved bone (majority benign) and 48.3% were soft tissue tumors (with a significant portion also benign), indicating a predominance of benign cases overall.
- * The hindfoot was the most common anatomical site for tumors, and while benign tumors have recognizable patterns that aid in early diagnosis, malignant tumors are rare and can appear sporadically, stressing the need for careful evaluation of any unusual masses.
Introduction: Minimally invasive calcaneal osteotomy (MICO) is already an established surgical procedure for correcting hindfoot deformities using a lateral approach. So far, no description of a medial approach for MICO has been published.
Material And Methods: Between August 2022 and March 2023, 32 consecutive patients (MICO with medial approach, MMICO: n = 15; MICO with lateral approach, LMICO: n = 17) underwent MICO as part of complex reconstructive surgery of the foot and ankle with concomitant procedures.
