Significant controversy exists in the literature regarding the pitfalls and benefits of minimally invasive total knee arthroplasty (TKA). Regardless, most surgeons today use smaller exposures than in previous years. Although more difficult, rigid adherence to classical gap balancing techniques can allow a surgeon to achieve ideal ligament and flexion/extension gap balance in TKA through a minim...

Our aim was to evaluate the cut-off value and efficiency of using reticulocyte hemoglobin content as a marker to diagnose iron deficiency anemia in Chinese adults. 140 adults who needed bone marrow aspiration for diagnosis at the hematology department of the Peking Union Medical College Hospital were enrolled according to the inclusive and exclusive criteria. Venous blood samples were collected...

The prevalence of antibodies against Leishmania donovani in selected domestic and wild animal species in 2 villages in Sudan with active L. donovani transmission in humans was investigated. Screening of domestic animals (donkeys, cows, sheep, goats, camels and dogs) with the direct agglutination test (DAT) detected reaction rates above the cut-off titres in donkeys (68.7%), cows (21.4%) and goa...

BACKGROUND The efficacy control for the treatment of bone metastases in breast cancer is difficult and usually initiated later and with longer time between treatment cycles than the restaging of visceral or soft tissue metastases. The amino-terminal propeptide (PINP) of type I collagen as a biochemical indicator of bone turnover might facilitate early and valid disease surveillance. The utility...

We compared, under laboratory conditions, the resistance to cutting out of the AO dynamic hip screw and the Pugh sliding nail. The mean load at cut out, adjusted for bone strength, was 70% greater for the Pugh sliding nail. The reasons for this difference are discussed.

OBJECTIVE To report the initial results from the use of a new technique for fixation of bone grafts in uncontained tibial bone defects in patients undergoing total knee prosthesis implantation. METHODS Six patients with severe varus deformity of the knee who, after cuts and ligament balancing had been performed, still presented bone deficiencies that reached the edge of the tibial cut and com...

OBJECTIVES The aim of this study was to evaluate the pattern of lingual split line when performing a bilateral sagittal split osteotomy (BSSO) for asymmetric prognathism. This was accomplished with the use of cone-beam computed tomography (CBCT) and three-dimensional (3D) software program. MATERIALS AND METHODS The study group was comprised of 40 patients (20 males and 20 females) with asymme...

Serum 25-hydroxyvitamin D concentration (25(OH)D) is considered the best marker of vitamin D status, with low concentrations indicating low status. However, cut-points for vitamin D deficiency and insufficiency vary, reflecting variable views among experts. Notably, the Institute of Medicine concluded in 2010 that there are no systematic reviews on the cut-points, and this still stands. Papers ...

This paper describes a system that assists in the planning and the performing of a surgical action, namely the corrective osteotomy of the thigh bone (femur). The cor-rective osteotomy of the thigh bone is used for changing the posture of the hip joint. During surgery, a small cross-sectional slice is cut out of the thigh bone by the use of a sawing device. Our system supports the planning phas...

Analyses and interpretations of the human behavioral significance of frequencies of cut-marked mammal bones have been ongoing for at least 50 years. Many of these studies focus on determining the so-called ‘‘butchering pattern.’’ Few analysts comment on the tremendous range of variation in frequencies and anatomical distributions of cut marks across multiple assemblages of remains of a taxon. S...
