Several methods are available using an endoprosthesis or biological reconstruction for malignant bone tumors. Methods that use allograft-prosthesis composites have shown promising results. In 1999, the authors developed a method of reconstruction that uses a tumor-bearing autograft treated with liquid nitrogen. This technique was modified to produce a pedicle frozen autograft to maintain anatom...

Disorders of the deep infrapatellar bursa are important to include in the differential diagnosis of anterior knee pain. Knowledge regarding its anatomic location can aid the clinician in establishing a proper diagnosis. Fifty cadaveric knees were dissected, and the deep infrapatellar bursa had a consistent anatomic location in all specimens. The deep infrapatellar bursa was located directly pos...

BACKGROUND Traumatic amputation of the digit requiring revision amputation at the level of the proximal phalanx provides the opportunity to improve flexor function via tenodesis of the remaining flexor digitorum superficialis (FDS) tendon. Salvage of the remaining FDS and performing flexor tenodesis to the proximal phalanx allows increased flexion at the metacarpophalangeal (MCP) joint. METHO...

we introduce a new concept of general $g$-$eta$-monotone operator generalizing the general $(h,eta)$-monotone operator cite{arvar2, arvar1}, general $h-$ monotone operator cite{xiahuang} in banach spaces, and also generalizing $g$-$eta$-monotone operator cite{zhang}, $(a, eta)$-monotone operator cite{verma2}, $a$-monotone operator cite{verma0}, $(h, eta)$-monotone operator cite{fanghuang}...

background: osteoporosis is a chronic disease that contributes substantially to decrease physical activity and decline in the quality of life. osteoporosis can be diagnosed easily with the use of dual-energy x-ray absorptiometry (dxa) equipment. the aim of this study was to investigate the magnitude of bone loss on proximal femur and lumbar spine ls in pre- and post-menopausal women from isfaha...

introduction: intramedullary nailing (imn) of high tibia fracture has some mechanical and biological advantages over the other form of fixation. however, valgus, apex anterior malalignment and anterior displacement of proximal fragment commonly occur after isolated imn fixation of proximal high tibia fracture. the purpose of this study is to determine the effectiveness of using 3.5-mm locking c...

BACKGROUND Surgical treatment of rotator cuff tears may be complicated by osteoporosis of the proximal part of the humerus. The purpose of this study was to determine whether pullout strength of suture anchors is affected by the location of the anchor placement and by bone mineral density. We hypothesized that higher bone mineral density is associated with higher pullout strength of suture anch...

BACKGROUND/AIMS Detection of proximal serrated polyps (PSPs) is increasingly recognized as a new qualitative target for colonoscopy. The aims of this study were to assess the detected prevalence of PSPs and synchronous adenomas in an asymptomatic average-risk screening cohort and to evaluate potential factors associated with detection of PSPs. METHODS The study included 1,375 asymptomatic ave...

Between 1985 and 2002 we treated 38 children with 39 fractures of the proximal tibia. Fractures affecting the proximal tibial physis were excluded from this study. Mean age at the time of injury was 7.1 years (range: 2.5 to 14). Conservative treatment was followed in 34 cases and four patients underwent surgery. We examined 31 children with 32 fractures followed up for an average of 4.8 years (...
