- Abstract:
- Objective To compare the clinical and radiological features of intra-/juxta-articular osteoid osteoma and extra-articular osteoid osteoma in skeletally immature patients.Discussing about characteristics、efficacy and prognosis of osteoid osteoma in intra-/juxta-articular. Methods Osteoid osteoma in 43 cases,31 boys and 12 girls,mean age at diagnosis was 8.9 years (range 1.8 to 16 years).They were dichotomized according to the loction of the nidus as intra-/juxta-articular (16 children) or extra-articular (27 children) or spine (3 children),review its distribution、clinical features、imaging features and treatment.then data using SPSS22.0 for statistical analysis. Results In this group of 16 cases of intra-/juxta-articular osteoid osteoma,only 6 cases had typical symptoms of osteoid osteoma,13 cases had synovial inflammation of the joint,10 cases had misdiagnosis,9 cases had characteristic nidus,and 8 cases had abnormal changes in bone around joint.indicating that the difference between the above data and the extra-articular group was statistically significant.which lead to an average of 17 months delayed diagnosis in this group.the p-value was less than 0.05,indicating that the difference in delay diagnosis between intra-/juxta-articular and extra-articular group was statistically significant.However,the clinical symptoms and imaging manifestations of extra-articular group were more typical.with excessive growth of tumor affected bones,but no significant clinical symptoms such as claudication. Conclusion Intra-/juxta-articular osteoid osteoma exhibit different clinical and radiological features from extra-articular osteoid osteoma.No typical clinical features,effects of synovitis,limp,an absence or minimal degree of osteosclerosis with subtle periosteal reaction,which is initially assigned to more common differential diagnoses,including inflammatory joint diseases or osteochondritis dissecans.Easy delay diagnosis,need precision surgery.
