background: in this experimental study, the radiographic and biomechanical characteristics of osteoperforated rabbit tibia during bone repair period were investigated. materials and methods: using dental drills, 2 mm holes were drilled at the mid-shaft of right tibia in 12 new zealand white rabbits. the left tibia was intact and selected as the control. x-rays of the left and right tibias were ...
abstract background: pseudoarthrosis of the tibia poses one of the most challenging treatment problems in all of orthopedics. the goal of the study was to assess the clinical outcome of intramedullary rod fixation in its treatment. methods: the results of the management for nine patients with pseudoarthrosis of the tibia with im rod fixation were reviewed retrospectively between 1986 - 2006...
an experiment with 300 one-day old ross male broiler chicks was conducted to determine the effects of glauconite and zeolite on the broiler's performance, tibia bone and blood characteristics. five experimental treatments [control, glauconite (2 & 4 percent), and zeolite (2 & 4 percent)] were used in a completely randomized design with 4 replicates. during the experiment weight gain, feed ...
BACKGROUND In total knee arthroplasty (TKA), cement penetration between 3 and 5 mm beneath the tibial tray is required to prevent loosening of the tibia component. The objective of this study was to develop and validate a reliable in vivo measuring technique using CT imaging to assess cement distribution and penetration depth in the total area underneath a tibia prosthesis. METHODS We defined...
Background: Fractures of distal tibia and pilon fractures are one of the most common fractures and are difficult to treat on account of, absence of muscle tissue attachment on lower 1⁄4 tibia and metaphyseal cancellous comminution. Most of them are compound fractures and result in poor blood supply to the distal tibia. The conventional technique of Open Reduction and Internal Fixation (ORIF) wi...
Clinical and experimental studies have demonstrated some negative effect of hypertension on bone mineral density. The aim of this study was to evaluate bone healing and trabecular bone area (TBA) in spontaneously hypertensive rats (SHR), a well-established model of essential hypertension, when compared to normotensive rats (NTR). A critical-size defect was surgically created in the right tibia ...
Large segmental bone defects of the tibia may be due to infections, high-energy fractures, congenital diseases or tumors and represent a challenge for both the physician and the patient. In developing countries, the use of expansive techniques is not possible so that amputation is sometimes proposed. However, an alternative technique for limb salvage, applicable in developing countries consists...
This study evaluated the application of laser-induced bone therapy (LIBT) to reduce implant healing time in rat tibia. Twenty 10-week-old female Sprague-Dawlay rats were used. The rats received laser irradiation (laser group) or sham operation (control group) on either side of the tibia. Five days after invasion, titanium implants were inserted in proximal tibia. Five, 10, and 20 days after imp...
