Osteoid osteoma is a benign bone tumor that rarely involves joints. Although there are several reports of arthroscopic osteoid osteoma excisions, to our knowledge, there are no reports of this type of treatment for osteoid osteoma in carpal bones. We report two cases of arthroscopic (a person who had a pain in the left wrist and the other one with carpal tunnel syndrome) with excision of oste...

Bone microstructure reflects physiological characteristics and has been shown to contain phylogenetic and ecological signals. Although mammalian long bone histology is receiving increasing attention, systematic examination of the main clades has not yet been performed. Here we describe the long bone microstructure of Xenarthra based on thin sections representing twenty-two species. Additionally...

Extracellular acidification by osteoclasts is essential to bone resorption. During proton pumping, intracellular pH (pH(i)) is thought to be kept at a near-neutral level by chloride/bicarbonate exchange. Here we show that the Na(+)-independent chloride/bicarbonate anion exchanger 2 (Ae2) is relevant for this process in the osteoclasts from the long bones of Ae2(a,b)(-/-) mice (deficient in the ...

the objective of the current study was to determine the anatomical features of the auditory ossicles inhamster. twenty temporal bones from 10 adult hamsters, weighing 275-300 g were used. after dissectingthem, the features of the ossicles were assessed with an ocular micrometer and photographed by astereomicroscope. finally, all data were evaluated and analysed using the sigma statt software. t...

Giant cell reparative granulomas (GCRG) are non-neoplastic rapidly expanding and locally destructive lesions typical of facial skeleton bones. Jaffé first described these lesions in 1953, designating benign lesions of the jaw that were histologically different from true giant cell tumors of long bones. Mandibular GCRG area rare lesions, comprising less than 7% of all benign bone lesions of the ...

An osteoblastoma is a primary benign bone tumor, which is rarely seen in hand bones. Osteoblastoma is generally seen in spine, pelvis, and long bones. However, there are a few case reports of osteoblastoma in wrist and hand bones. To our knowledge, up to now, only one male patient with osteoblastoma in capitate bone was reported. We report the first female case of osteoblastoma of capitate bone...

Introduction: Non-ossifying Fibroma (NOF) is a relatively common benign and non-neoplastic lesion in long bones of children and adolescents. As far as very few cases of NOF have been reported in jaws and what was managed to be found regarding all reported cases having occurred only in the mandible, in this article we are going to report a case of maxillary NOF in a 38-year-old female.

introduction: non-ossifying fibroma (nof) is a relatively common benign and non-neoplastic lesion in long bones of children and adolescents. as far as very few cases of nof have been reported in jaws and what was managed to be found regarding all reported cases having occurred only in the mandible, in this article we are going to report a case of maxillary nof in a 38-year-old female.

On the basis of the standard measurements of 1277 long appendicular bones of the domestic sheep, a universal point scale has been elaborated. The bones examined were obtained from European, Asian and African archaeological sites dating from 4500 BC to 1500 AD. A comparative analysis of the metapodial bones of the domestic sheep from Central Europe (Poland, Germany and Hungary) has been undertak...
