Abstract: Apoptosis is triggered by disruption of healthy skeletal structure, leading to BSI. Stress fractures that make training and competitive performance difficult can result from BSI, which are commonly underestimated and mistakenly classified as muscle or tendon injuries. The best way to reduce the chance that microfractures may develop into larger ones is to identify them early. Imaging methods like radiography, CT, and MRI can help with management decision-making, training return, and injury recurrence prediction. 106 patients who had been undergoing intense training for the previous two weeks at the tertiary care hospital and complained of lower limb pain were the subjects of a hospital-based prospective case-control study. Radiography, US, and specialized MRI were performed on every patient. In contrast to the controls, which included patients who complained of lower limb discomfort but did not exhibit bone stress injuries on MRI, the cases included patients who had bone stress injuries verified by MRI. Following the proper data filtering, Medcalc (vs. 20.0) was used to transmit and evaluate the data sheet. In the study, majority were male (98.1%), age distribution varied, with 43.4% of participants aged 21-30 years, 35.8% under 20 years, and 20.8% over 30 years. Tibial involvement was predominant among cases (92.2%), with the right side being more commonly affected for both tibial and fibular injuries. The most frequent injury grade was Grade 4b (37.2%), followed by Grade 1. Radiography showed a sensitivity of 41.18% and an accuracy of 71.70%, whereas ultrasound (USG) demonstrated higher accuracy (89.62%), with better sensitivity and specificity. Radiography is accessible but has low sensitivity (41.18%) for early bone stress injury (BSI) detection. Ultrasound, with higher sensitivity (78.43%) and perfect specificity (100.00%), is a valuable adjunct, offering insights into soft tissue involvement and early bone stress reactions, and guiding therapeutic interventions effectively.
