Abstract: | Introduction Transient osteoporosis or the bone marrow oedema syndrome is described as a self-limiting disorder. Transient osteoporosis usually affects only one bone, predominantly the proximal femur. Involvement of the foot is rare and often overlooked. A disorder of the navicular bone of the foot can be found twice in the literature.Materials and methods We report a case of transient osteoporosis of the navicular bone of the foot in a 20-year-old, female, top-level track athlete (400 m sprinter) treated with alendronate, and a review of the literature.Results The therapeutic options are limited, frequently consisting of non-specific, symptomatic therapy. Some authors report favourable results with core decompression, while others have reported good results with a conservative regime of symptomatic treatment and avoidance of weight-bearing until the clinical and radiological changes have resolved. In the described case, the patient had a favourable result after a short course of treatment with alendronate. She experienced almost immediate pain reduction and presented a complete resolution of the abnormal signal intensity on MRI.Conclusion This rapid result makes the use of alendronate seem promising in athletes with transient osteoporosis, permitting an early return to high-level activities. |
