Ewing's Sarcoma of the Sacroiliac Joint Presenting as Tubercular Sacroiliitis: A Diagnostic Dilemma

We report a case of Ewing's sarcoma of the sacroiliac joint in a 21-year-old male mimicking tubercular sacroiliitis, a rare entity not reported in literature. He presented with pain in the lower back radiating to the right lower limb along with constitutional symptoms of 3 months duration. On examination, the right sacroiliac joint was tender. The laboratory investigations showed anaemia, leukocytosis and raised erythrocyte sedimentation rate. On X-ray, features of right sacroiliitis were seen. This was further investigated with magnetic resonance imaging (MRI), which showed features consistent with tubercular sacroiliitis. Patient was then started on antitubercular treatment, but the improvement was not consistent. So, a contrast MRI was done, which indicated features of primary sarcoma. It was then further confirmed by a computed tomography-guided biopsy, which showed features consistent with Ewing's sarcoma of the sacroiliac joint.

Results of titanium elastic nailing in paediatric femoral diaphyseal fractures----report of 30 cases / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>Fractures of the femur are the most incapacitating fractures. For children aged 6-14 years, there is no clear consensus as to the preferred treatment. The conventional treatment of traction and casting is no longer recommended. We report our experience in titanium elastic nailing for treatment of paediatric femoral diaphyseal fractures.</p><p><b>METHODS</b>Thirty patients in the age group of 6-16 years with displaced diaphyseal femoral fractures were stabilized with titanium elastic nails. Patients were followed up clinically and radiologically for a minimum period of 1 year. The final results were evaluated using Flynn's criteria. Technical difficulties and complications associated with the procedure were also analysed.</p><p><b>RESULTS</b>Overall results were excellent in 20 cases and satisfactory in 10 cases. No patient had poor result. The average hospital stay was 9 days. All the fractures healed with an average time to union of 6.86 weeks. The most common complication encountered was soft tissue irritation at the nail entry site seen in 6 cases. Clinically, lengthening was noticed in 4 cases, while no patient had shortening. Malalignment was seen in only 6 cases. Perioperative difficulties encountered were failure of closed reduction seen in 6 cases and corkscrewing of nails in one case.</p><p><b>CONCLUSION</b>Titanium elastic nails are a relatively easy to use, minimally invasive, physeal-protective implant system with high rate of good and excellent outcomes in children aged 6-16 years. Technical pitfalls can be eliminated by adhering to the basic principles.</p>
