This study redescribes an arthroscopic bridge technique for repair of avulsion of the posterior cruciate ligament. The procedure is performed step-to-step. In this technique we created two bone tunnels in the anterior aspect of the tibia and inferior medial of the tibia tuberosity and then create suture fixation of the fragment using the suture bridge. The arthroscopic bridge technique was used...
background: total knee arthroplasty is a complex procedure aiming to relieve pain and improve function. it is critical to select prosthesis that best cover the bone surfaces. ethnicity may affect fitness of the components mainly designed for caucasian populations. this study aimed to evaluate morphometric features of proximal tibia in iranian population. methods : during 2013, 150 consecutive...
Osteoarthrosis (OA) is a multi-factorial disease characterized by the progressive loss of articular cartilage and the development subchondral sclerosis, intra-osseous cysts and osteophytes. In addition to changes in cartilage which occur in OA, it is suggested that early changes are seen in the adjoining subchondral and trabecular bone (1). In this work we develop, optimize and extend MR techni...
of about half an inch, and underneath, to nearly the same distance, the soft parts had receded from the tibia, leaving a outjutting right angle of denuded bone; still, although tho soft parts had thus receded, or probably sloughed, from its sharp edge, they had in no way deserted the tibia. Appearing to have considered that the flaps could not heal over a bony edge of such extreme sharpness, th...
PTH and mechanical loading might act synergistically on bone formation. We tested the in vivo effect of the L-type voltage-sensitive calcium channel (VSCC) blocker, verapamil, on bone formation induced by human PTH-(1-34) (PTH) injection with or without mechanical loading. Adult rats were divided into eight groups: vehicle, verapamil, PTH, or verapamil plus PTH with or without mechanical loadin...
Many postmenopausal women have vitamin D and calcium deficiency. Therefore, vitamin D and calcium supplementation is recommended for all patients with osteopenia and osteoporosis. We used an experimental rat model to test the hypothesis that induction of osteoporosis is more efficiently achieved in peripheral bone through combining ovariectomy with a unique multi-deficiencies diet (vitamin D de...
We used dual-energy X-ray absorptiometry (DEXA) to measure the bone mineral content (BMC) of both tibiae in 13 patients who had been treated for a tibial fracture by rigid plate fixation. Within two weeks of plate removal the BMC was significantly greater in the bone that had been under the plate than at the same site in the control tibia. An unplated area of bone near the ankle showed a signif...
The safety and effectiveness were examined of the spirulina alga on bone metabolism in ovariectomized estrogen-deficient rats and hindlimb-unloaded mice. The dosage range was from an amount equal to that recommended in so-called health foods for humans (0.08 g/kg BW/day) to a 100-fold higher dose. The bone mineral density (BMD) of the whole femur and tibia of ovariectomized rats in the any spir...
Many elements are responsible for the balance in bone tissue, including those which constitute a substantial proportion of bone mass, i.e., calcium, phosphorus and magnesium, as well as minor elements such as strontium. In addition, toxic elements acquired via occupational and environmental exposure, e.g., Pb, are included in the basic bone tissue composition. The study objective was to determi...
The aim of this research was to evaluate the process of bone regeneration in rabbits, using chitosan and beta-tricalcium phosphate (β-TCP) independently and in combination. A total of 12 New Zealand rabbits of both sexes, with average weight of 3.0 ± 0.57 kg were used. Animals were randomly divided into two experimental time points, with six animals euthanized 45 days after surgery and six euth...
