Cortical Bone Trajectory Screws for Middle Upper Thoracic: a Anatomico-Radiological Study Introduction Pedicle screw fixation system has been widely used in spinal surgery due to its biomechanical advantage in three-dimensional fixation and short-segment fixation. However‚ Complications such as screw loosening‚ pullout and broken‚ often lead to loss of surgical construct stability‚ particularly in patients with poor bone quality [1-4]. The cortical bone trajectory (CBT)[5] technique is a theoretical

Where the cartilage covering the ends of the bones progressively roughens and becomes thin‚ and the bone underneath thickens .This leads to immense pain‚ deformity‚ swelling of the joint. There are three surgical options: Ankle fusion – Ankle fusion involves removing the damaged ankle joint and fusing the talus bone to the tibia to form a stiff ankle. Triple fusion – Triple fusion is the surgical fusion of three joints‚ either

Fractured Femur. Definition : A femoral fracture is a bone fracture that involves the femur. It includes hip fractures. Causes of fractured femur : The femur is a tremendously strong bone‚in order for a femur fracture to occur‚ either a large force must be applied or something is wrong with the bone. In patients with normal bone strength‚ the most common causes of femur fractures include: -Car accidents -Falls from a height Patients may also have bone that is weakened by osteoporosis‚ tumor‚ or infection

A bone scan revealed reduced bone mass in the head and neck regions of the injured femur‚ in other long bones of the body and in the vertebrae‚ suggestive of osteoporosis. Surgery was required to repair the femur‚ and a biopsy of the bone tissue revealed that the composition of the osteoid is normal. Healing of the fracture is proceeding slowly. 1.

Fibrous connective tissue also holds body parts together‚ but its structure is a bit more rigid than loose connective tissue. Fibrous connective tissue is found in ligaments‚ tendons‚ cartilage‚ and bone.

As you age it takes longer for bone to form. Osteoporosis is caused when you lose bone mass quicker than new bone mass is formed. Calcium‚ Vitamin D‚ and Phosphate are needed to form bone. Insufficient amounts of these minerals can cause bones to become brittle and weak over time. (Mayo Clinic Staff‚ 1998-2013) “The leading
