The Analysis Of The Clinical Diagnosis And Treatment Of Enchondroma In Long Tubular Bones

Objective:We collect and analyze these enchondroma in long tubular bones cases admitted to our hospital in the last five years, in order to study the clinicopathologic features and treatment of enchondroma in long bones.Methods:We collect44cases of enchondroma in long tubular bones diagnosised by clinical data admitted by our hospital from January1st2009to December31st2013. By pathologic features, the incidence age and location, clinical manifestation, imaging findings, surgical approach and outcomes, these case are classified into different groups to analyze. Results:A total of44cases,40cases were confirmed as enchondroma by pathology, and other4cases were low-grade chondrosarcoma. According to the classification of the incidence location, femoral group accounts for38.1%, humerus group accounts for38.1%, tibia bone group accounts for16.7%, fibula group accounts for7.1%.26cases (accounting for65.0%) had clinical manifestation, and the presence of pain was the main manifestation. The X-ray, CT and MRI showed lesions in the metaphysis and diaphysis, and most lesions demonstrated characteristic calcifications that can be variable in extent. MRI showed low signal on T1WI and high signal, including foci of low signal on T2WI. Periosteal reaction, cortical destruction and soft tissue were not found. All the44cases were underwent surgical treatment, and36cases underwent curettage, inactivation and packing with bone graft material.37cases were effective follow-up and all cases have no recurrence and malignant transformation.Conclusion:The femur is the most common tubular bone involved followed by the humerus and tibia. Radial, ulnar, and fibular lesions are less frequent. The patients often have no clinical manifestation, and the presence of pain is the main manifestation. The radiologic(X-ray, CT and MRI) and pathologic features improve the ability to diagnosis.Distinguishing enchondroma from low-grade chondrosarcoma is often difficult. Curettage, inactivation and packing with bone graft material is the typical method of surgical excision and usually achieves satisfactory outcomes.
