Post-traumatic Osteolysis Of Bone Simulating A Malignant Lesion

Objective To discuss the clinical manifestation, radiographic features, mechamism of disease, diagnosis, differential diagnosis and treatment of posttraumatic osteolysis (PTOL).Methods Through analyzing clinical manifestation, radiographic features and pathological manifestation of 7 cases of posttraumatic osteolysis.Results Clinical Features: Six cases resulted from acute trauma, and one case was caused by sports-related repetitive microtrauma. All the cases had similar clinical presentations that included pain with decreased joint range of motion. The most commonly seen position was the distal clavicle, pubis and ischium. Radiographic changes are varied. The symptoms could be relived after conservative care. Follow-up radiographic examination, when performed demonstratedreconstitution of the former osteolysis of various degrees, although lagging behind clinical evidence of improvement.Conclusion Post-traumatic osteolysis may result from acute trauma or repetive microtrauma in specific position. Radiographic changes are varied, including irregularity of bone marrow edema, cystic erosions, cortical thinning or irregularity, and blatant osteolysis. It is difficult for us to early diagnosis.MRI can enhance the rates of the early diagnosis.Pay attention to the differential diagnosis with the malignant lesion. Postitive outcomes may be achieved with conservative care. It may be changed the osteolytic process with using the osteolysic inhibitor.
