Fracture of Tibia is the most common amongst pediatric fractures. Most tibial shaft fractures are treated conservatively with close reduction and above knee cast application. Surgery is indicated only when the fracture is unstable, open fracture and associated with multiple injuries. Flexible intramedullary nailing is commonly used for diaphyseal tibial fracture and is also well used in other l...
conclusions we found the magnetic field assistant device to be an accurate, radiation-independent jig for close passing of guide wire after close reduction of femoral fracture. it can reduce the need for radiation during placement of guide wire for closed intramedullary nailing of the long bones. more studies are required to improve and evaluate the technique and equipment. results outcomes of ...
introduction: intramedullary nailing (imn) of high tibia fracture has some mechanical and biological advantages over the other form of fixation. however, valgus, apex anterior malalignment and anterior displacement of proximal fragment commonly occur after isolated imn fixation of proximal high tibia fracture. the purpose of this study is to determine the effectiveness of using 3.5-mm locking c...
The biomechanical performance of a locking compression plate system was compared to an intramedullary photodynamic bone stabilization system in a femur and humerus osteotomy model. The photodynamic bone stabilization system utilizes an angioplasty-like balloon that is introduced into the intramedullary canal of a fractured bone, filled with monomer that is then polymerized and hardened by visib...
Patients with spinal abnormalities infrequently present with intradural intramedullary bleeding. The more common causes include spinal trauma, arteriovenous malformations and saccular aneurysms of spinal arteries. On occasion, spinal cord tumors either primary or metastatic may cause intramedullary bleed with ependymoma of the conus medullaris. Spinal nerve sheath tumors such as schwannomas onl...
Spinal intramedullary tuberculoma remains a very rare entity of central nervous system tuberculosis. This is the same with the coexistence of spinal intramedullary and intracranial tuberculomas that remains extremely rare with less than 20 cases reported at present. Authors describe this uncommon case by analyzing a 65-year-old female patient who had past history of kidney transplantation due t...
Cysticercosis is an endemic condition in many developing countries. Although it is the most common parasitic disease of the central nervous system, cysticercal involvement of the spinal cord is rare. It may occur as intradural extramedullary, intramedullary, intramedullary associated with intradural-extramedullary or as the vertebral presentation. We report the case of a 53-year-old woman who p...
Background Intramedullary, nondysraphic, spinal cord lipomas are rare and account for less than 1% of all spinal cord lesions. Symptoms typically consist of a progressive myelopathy associated with increasing degrees of paralysis (e.g., quadriparesis/plegia, paraparesis/plegia). Case Description A 39-year-old male, without a history of spinal dysraphism, presented with a progressive spastic q...
BACKGROUND Cysticercosis is a parasitic disease caused by the larval stage of Taenia Solium. Involvement of the central nervous system by this tapeworm is endemic in developing countries. However, isolated spinal involvement by Taenia Solium is uncommon and having clinical presentation of Brown-Séquard syndrome is even rarer. CASE PRESENTATION A 43-year-old male who came to the emergency depa...
Eccentric reaming of cortical bone near a fracture site can introduce malalignment when an intramedullary nail is placed. The authors describe a technique of reaming metadiaphyseal and diaphyseal femur fractures in which maintaining reduction at the fracture site is not necessary to obtain an excellent alignment of long bone fractures after intramedullary nailing. They have found that central r...
