Preintervention maximum nidus diameter, pain score, and edema diameter were significantly lower in postintervention measurements ( < 0.001). Technical success rate was 98.1%, and clinical success was 96.36%. Severe complication occurred in one patient with soft tissue burn and osteomyelitis. This is one of the largest series of osteoid osteoma treated with RFA done in a single center with atypical cases. In conclusion, RFA is safe and effective in both pediatric and adult patients with rare complications even in challenging cases with atypical locations.

In this case report, we describe a case of complete missing lateral column of the distal humerus with severe articular destruction of capitellum and lateral trochlear ridge which was treated with the patient-specific implant created with three-dimensional printing technology. Apart from anatomic replacement of the articular surface, the lateral collateral ligament complex and extensor muscle which are the key soft tissue stabilizers of elbow were repaired by reattaching their bony origins to the impacted iliac crest bone graft inside the implant. Due to the favorable result at 2-year follow-up, this modality is a potentially viable surgical option in treating of the severe open distal humeral fracture associated with entire lateral condylar damage.Trisubstituted benzimidazoles (trisbenz) are significantly active against nonreplicating Mycobacterium tuberculosis (MTB) by inhibiting the polymerization o
