In elderly patients frequent episodes of joint pain of lower limbs exacerbated by stress and resistant to treatment occur frequently. This paper reports a case of a long lasting bilateral atraumatic knee pain with a final diagnosis of bilateral stress fractures of proximal tibia in osteoporotic postmenopausal woman. The distinctive trait of this case is that the fracture has set in bilaterally and associated with an isthmic L4-L5 spondylolisthesis in a patient afflicted by a decline in mood. This particular clinical picture has delayed the diagnosis and the suitable treatment for 3 years. Therapy for this type of patients must aim in the acute phase at pain relief and only after must be settled in a long term antiosteoporotic therapy. We choose clodronate acyd for pain relief and after strontium ranelate for osteoporosis prevention.
