Swelling and inflammation after rhBMP-2 use are dose-dependent. Swelling may be due to direct contact as well as spread in the plane of access. The causes are a robust inflammatory reaction as well as sterile seroma and encapsulated hematoma formation.

A wide spectrum of pediatric corpus callosal diseases can occur in the pediatric age group. Cross-sectional magnetic resonance imaging plays an important role in the diagnosis of these patients. We reviewed our imaging record and collected cases of corpus callosal pathology. The purpose of this review is to illustrate the imaging features of various corpus callosal lesions encountered in children.

Epithelioid sarcoma is a rare malignant soft tissue neoplasm commonly involving extremities of young adults and rarely occurring in the trunk area. It re-sembles a chronic inflammatory process and mimics benign reactive granuloma or other benign diseases. Despite its indolence and slow growth, the prognosis is poor with high recurrence and early lymph node spreading and hematogeneous distant metastasis. Involvement of the spine is extremely rare and diffi-cult to diagnose correctly in clinical p

Titanium alloy(Ti-6Al-4V, Samsung techwin, Korea) rods with diameter of 2.5mm were used as the implant materials. Polymethyl methacrylate(PMMA) bone cements(CMW, USA) were used as bone cement and -tricalcium phosphate(TCP)-based bone filler powder was used as osteoconductive additives. Hydroxyapatite(HA) was the desired end product after hydrolysis of the -TCP-based bone filler powder mixed with the blood. In animal study using rabbits, we divided the group into A, B, C and D. Rabbits were sacri
