Effect of transported segment size on the new bone formation of the rabbit femur in the Ilizarov bone transport method.

Objective: This study aimed to compare histological and radiological union in the bone transport of 3 segments of different sizes to reconstruct the rabbit femur's bone defects.

Methods: Thirty rabbits were divided into 3 groups; a 1-cm defect was created in the femur in all rabbits. The length of the segment to be transferred was 10% of the femur length in group 1, 15% in group 2, and 20% in group 3.

Biomechanical comparison of fixation methods on third-generation femoral composite bone models in Pauwels type 3 femoral neck fractures: Contribution of the medial buttress plate to fixation.

Objective: To compare the use of cannulated screws in an inverted triangular configuration, medial buttress plates, and the combination of these 2 fixation methods in the treatment of Pauwels type 3 femoral neck fractures.

Methods: Twenty-eight anatomical composite third-generation femoral bone models were divided into 4 groups. The control group (group 1) was formed with 7 third-generation intact bone models.

Biomechanical and fracture characteristics of different filling and fixation methods applied to various proximal tibial metaphyseal defect sizes in an ovine model.

Background: Ideal treatment method based on the size of the defect in local aggressive bone tumors is yet to be described. We evaluated the mechanical behavior of different fixation methods for various defect sizes located in the proximal tibia.

Methods: Ninety-one sheep tibiae were distributed in five groups.

Cementless rectangular stems yield satisfactory results in osteoporotic bones.

Background: The present study aims to investigate the effects sof osteoporosis on prosthesis survival by comparing the femoral stem survival rates of patients with poor and relatively good bone quality.

Methods: We retrospectively investigated 61 patients with collum femoris fractures who were treated with cementless rectangular stems between 2011 and 2015 in the Orthopaedics and Traumatology Clinic of Taksim Training and Research Hospital. The preoperative pelvic anterior-posterior radiographs of the patients were evaluated.

Behaviour and knowledge skill levels of orthopedic surgeons about radiation safety and fluoroscopy use: A survey analysis.

Objective: The aim of this study was to evaluate the behaviour and knowledge skill levels of Turkish orthopedic surgeons about fluoroscopy usage and radiation safety.

Methods: The questionnaire, consisting of nineteen questions, was sent to orthopaedic surgeons and requested by a total of 323 surgeons online. The questions were about personal information, training and behaviours related to radiation and fluoroscopy usage, and the use of protective equipment.
