Skeletal integrity in meat-type chickens is affected by many factors including rapid growth rate, nutrition and genetics. To investigate the genetic basis of bone and mineral metabolism, a QTL detection study was conducted in an intercross between two lines of meat-type chickens divergently selected for their high (D +) or low (D -) digestive efficiency. Tibia size (length, diameter, volume) an...
Mechanical and kinematical aligning techniques are the usual positioning methods during total knee arthroplasty. However, alteration of the physiological joint line and unbalanced medio-lateral load distribution are considered disadvantages in the mechanical and kinematical techniques, respectively. The aim of this study was to analyse the influence of the joint line on the strain and stress di...
This study discusses the results of a histological examination of bone calluses in the treatment of tibia fractures in sheep with the involvement of a semi-circular fixator. In all sheep, callus samples revealed the presence of well-developed, compact bone tissue in the area of fracture healing. It was found that the use of a semi-circular fixator promoted bone growth, and that it is an effecti...
We present an elderly patient with a squamous cell carcinoma over the subcutaneous aspect of the leg involving the tibia. En bloc resection of the tumour together with a 10 centimetre segment of the tibia was done. The resected bone was autoclaved, replaced in its original position and stabilized with bone cement and a locked nail. This allowed early ambulation with minimal cost.
BACKGROUND/AIMS In a randomized controlled clinical trial in kidney transplant recipients (NCT01377467) we have recently shown that RANKL inhibition with denosumab significantly improved areal bone mineral density (aBMD) when given during the first year after transplantation. The effect of denosumab on skeletal microstructure and bone strength in kidney transplant recipients is not known. MET...
Ankle arthrodesis is commonly used in the treatment of ankle arthritis. The present study compared mesenchymal stem cell (MSC) bone allografts and proximal tibia autografts as adjuncts in performing ankle arthrodesis. A total of 109 consecutive ankle fusions performed from 2002 to 2008 were evaluated retrospectively. Of the 109 fusions, 24 were excluded from the present study, leaving 85 patien...
OBJECTIVE The objective of this study was to evaluate the effectiveness of the treatment of infected nonunion of tibia and femur by bone transport. MATERIAL AND METHODS We retrospectively reviewed 110 patients with infected nonunion of tibia and femur treated by bone transport. Our study included 92 males and 18 females with a mean age of 38.90 years. The site of infected nonunion involved 72...
We measured the extent and rate of new bone formation over an 18-month period before, during and after the lengthening of ten leg segments in six patients aged between 8 and 18 years, using dual-energy X-ray absorptiometry (DEXA). New bone formation could be identified within one week of the start of distraction. As lengthening proceeded, the bone density of the gap fell, reaching minimum value...
Some studies based on bone biopsy have demonstrated that in patients with tumor-induced osteomalacia (TIO) the mineralization process of matrix is profoundly disturbed. However, interrelationship between clinical and biochemical features microarchitecture this disease needs further analysis. With purpose mind, we set out three objectives: (i) to determine estimated strength a group using high-r...
BACKGROUND Bone can adjust its morphological structure to adapt to the changes of mechanical environment, i.e. the bone structure change is related to mechanical loading. This implies that osteoarthritis may be closely associated with knee joint deformity. The purposes of this paper were to simulate the internal bone mineral density (BMD) change in three-dimensional (3D) proximal tibia under di...
