ABSTRACT
Introduction: Osteoid osteoma is a benign bone tumor, which has no growth potential, consequently its size does not exceed 1.5 cm despite the fact that the surrounding sclerosis gives it a larger appearance. It most often affects young men, most often appearing in the first three decades of life.Objectives: To show the biomechanical repercussions derived from an osteoid osteoma in the trajectory of the iliotibial band and its influences by descending muscle chains on the lower limb.
Case report: We report a 24-year-old female patient who came to the consultation due to pain on the external face of her right femur for two years. This pain worsened mainly by walking. After carrying out the pertinent explorations and diagnostic imaging tests, no significant clinical findings were observed, therefore, oral anti-inflammatory treatment was prescribed and biomechanical and postural study was carried out, which showed bilateral, unstable valgus foot, with higher relevance on the right foot. The patient came again when she had no improvement, telemetry of her lower limb and magnetic resonance imaging of her right femur were performed. The diagnostic image revealed the presence of a mass compatible with an 11 x 4 mm osteoid osteoma in the proximal lateral third of her right femur.
Conclusions: A neoplastic lesion that affects the trajectory of a muscle group with biomechanical repercussions can carry out compensations at different levels, therefore, the action of a multidisciplinary team is necessary to restore gait. Synergies between conservative and surgical treatment lead to a higher success rate.
