Interface between titanium miniplate/screw and human calvaria.
This study demonstrates interfacial changes of titanium miniplate/screw with normal calvaria and nonvascularized calvarial bone graft ensued from craniectomy in a 53-year-old female. In 18 months after operation, a right parietal bone containing an L-shaped miniplate with screws, 5 mm long and 2 mm in external diameter, was harvested, fixed, and embedded in methylmetacrylate. Fifteen micrometer...
متن کاملPrimary osteogenic sarcoma of the calvaria.
Osteogenic sarcoma of the skull is rare [1-7], particularly as a primary development in the later decades of life without associated Paget disease or history of irradiation. Because of the paucity of cases, the radiologic findings of calvarial osteogenic sarcoma have not been described in detail. Previous reports have dealt mainly with plain skull radiographs for the diagnosis of this tumor bef...
متن کاملHistologically benign pleomorphic adenoma of the calvaria.
Pleomorphic adenoma or benign mixed tumor is the most common salivary gland tumor. It is most frequently located in the parotid gland, and is considered to be a benign neoplasm accounting for 70-80% of all benign tumors of the salivary glands [1]. Benign metastasizing pleomorphic adenoma is extremely rare, with only a handful of cases described. We report a case of a histologically benign mixed...
متن کاملThe results of compression forces applied to the isolated human calvaria.
Data for the force necessary to fracture the isolated calvaria (skull cap) are not available in the extant literature. Twenty dry adult calvaria were tested to failure quasistatically at the vertex using a 15-kN load cell. The forces necessary to fracture or cause diastasis of calvarial sutures were then documented and gross examination of the specimens made. Failure forces had a mean measureme...
متن کاملHuman parathyroid hormone fragment stimulates the de novo synthesis of prostaglandin endoperoxide synthase in chick calvaria
The human parathyroid hormone N-terminal fragment [hPTH-(1-34)] increases the conversion of exogenous unsaturated fatty acids to prostaglandins (PGs) in calvarial homogenates. Enzyme activities were completely blocked by indomethacin (5 x 10(-7) M), a PG synthase inhibitor, and actinomycin D (5 muM), an inhibitor of transcription, by binding to DNA. In addition, a potent inhibitor of protein sy...
