Recent improvements in digital C-arm radiographic units permit the safe and effective performance of cerebral angiography in the operating room. Intraoperative cerebral angiography, in turn, facilitates more effective aneurysm surgery and arteriovenous malformation therapy (1 , 2]. A variety of radiolucent carbon fiber head holders are now available for use in neurosurgical procedures that invo...

A benign bone neoplasm known as an osseous fibroma is frequently referred fibro-osseous lesion. It has a stronger preference for females and thought to have originated from periodontal membrane. Maxilla less often afflicted than the mandible. This made up of highly cellular, fibrous tissue with varied levels calcified tissue, which may resemble cementum, bone, or both. Depending on degree calci...

BACKGROUND Stable and well-aligned placement of tibial components during primary total knee arthroplasty is challenging in patients with bone defects. Although rectangular block-shaped augmentations are widely used to reduce the shearing force between the tibial tray and bone compared with wedge-shaped augmentations, the clinical result remains unclear. This study aimed to evaluate the outcome ...

Abstract Background The FINE total knee was developed in Japan and clinical use began 2001. It has unique design features, including an oblique 3 o femorotibial joint line that reproduces anatomical geometry. Although 20 years have passed since the clinically used for first time Japan, a formal evaluation patient-reported radiographic outcomes not been undertaken. Methods A of 175 consecutive p...

The orthokeratinized odontogenic cyst (OOC) is a rare developmental odontogenic cyst that has been considered as a variant of the keratocystic odontogenic tumour (KCOT) until Wright (1981) defined it as a different entity. Surgery is the usual treatment, and recurrence or association with Gorlin-Goltz syndrome has rarely been described. In this report, we presented three cases of this pathology...

Early implants for total knee replacement were fixed to bone with cement. No firm scientific reason has been given for the introduction of cementless knee replacement and the long-term survivorship of such implants has not shown any advantage over cemented forms. In a randomised, prospective study we have compared cemented and uncemented total knee replacement and report the results of 139 pros...

Eighty-six nonhinged total knee arthroplasties performed between 1971 and 1981 have been reviewed. Fifty-one were of the geometric type and 35 of the anametric type. The use of both units resulted in a statistically and clinically significant improvement in preoperative pain and an increase in functional activities. Three of 51 geometric units developed loose components that required revision. ...

Recent in vitro work has shown that sealing the acetabular notch with bone graft in bovine acetabulum samples results in improved cement penetration in the acetabular bone during total hip arthroplasty. Successful sealing of the notch may be identified on postoperative films by a lack of cement extrusion. This study aimed to assess the clinical effectiveness of this technique in preventing ceme...

Between January 1988 and January 1991 we performed 100 consecutive cemented total hip replacements using a zirconia head, a titanium alloy stem and a polyethylene cup. We reviewed 78 of these hips in 61 patients in detail at a mean of 5.8 years (1 to 9). Aseptic loosening was seen in 11 hips (14%). Eight needed revision. In total, 37 cups (47.5%) showed radiolucent lines, all at the cement-bone...
