Epidemiological and radiological characterization of fibrous bone defects. Bone tumors unit of the CMDLT

Abstract

Introduction: Fibrous bone defects, also known as cortical fibrous defect, metaphyseal fibrous defect and non-ossifying fibroma, are benign lesions of bone tissue, to date they have no known cause, around 30-40% of patients are less than 20 years old. Clinically it presents with pain (40% of cases), but, in 20% of cases, it appears as a finding and has also been associated with pathological fractures, it usually affects more males and has a predilection for bone metaphysis long. Methods: The research was retrospective, observational, descriptive of case series, cross-sectional. Results: the age of the patients evidenced was the class interval between 10 to 14 years (46.15%); the predominant sex was male with ten (10) cases (76.92%); in the radiomorphological stage, for Stage A there were seven (7) for 53.85%; the number of lesions evidenced was unique once (11) cases with 84.62% and for the location of the lesion, the proximal tibia with seven (7) cases for 53.85%. Conclusions: It is concluded in the present investigation that it responds to the general objective proposed on how to determine the epidemiological and radiological characterization of fibrous bone defects in patients treated in the Bone Tumor Unit of the La Trinidad Teaching Medical Center in the period January 2017 - December 2020; because useful information was obtained regarding the clinical picture, certain demographic and radiomorphological characteristics of the patients with this pathology.
