Uncorrected bony deformity or stiffness resulting from a metacarpal shaft fracture can produce a significant functional or cosmetic deficit. Intramedullary fixation of metacarpal shaft fractures using small flexible rods can provide stable internal fixation while minimizing the extent of soft tissue trauma that is associated with more extensive surgical techniques such as plate or screw fixatio...

The development of a medical surgical tool packaged with micro sensors for transmission of Supermedia information over the Internet is described in this paper. We define Supermedia as a set of communication media, which encompasses acoustic, force, visual, audio, temperature, tactile, and chemical (e.g., taste an smell) information, and which can be physically experienced by a communicator. In ...

STUDY DESIGN Retrospective case series. PURPOSE To investigate the relationship between tumor location and clinical characteristics. OVERVIEW OF LITERATURE Hemangioblastoma is a rare disease that develops in the central nervous system. Magnetic resonance imaging (MRI) is useful to evaluate hemangioblastomas. Hemangioblastoma's location is designated as intramedullary, intramedullary+extrame...

The effect of the longitudinal stretching force of the spinal cord on intramedullary pressure was investigated using our method for measuring intramedullary pressure of the spinal cord with implanted balloons. The transverse compressive force against the posterior wall of the spinal column was excluded by measuring the intramedullary pressure during flexion of the head with the middle and lower...

BACKGROUND AND PURPOSE Studies systematically evaluating the detection of intramedullary spinal cord metastasis with PET are lacking. Our purpose was to evaluate the visibility of intramedullary spinal cord metastasis on PET in a single institutional series and to correlate PET and MR imaging features. MATERIALS AND METHODS Patients were included if pretreatment MR imaging identifying an intr...

Antegrade telescoping rods have been introduced for use in pediatric patients with osteogenesis imperfecta (OI) to decrease the incidence of long-bone fractures and to correct and prevent deformities. Recent studies have documented failures of telescoping intramedullary rods due to inadequate distal fixation. The purpose of this study was to evaluate the pullout strength of distal fixation of t...

Blocked intramedullary osteosynthesis has become a "gold standard" for the treatment of patients with diaphyseal fractures tibia. However, there is still debate about importance and necessity reaming bone marrow cavity when performing osteosynthesis. The aim to study individual features structure medullary tibia in relation osteosynthesis, as well evaluate effect blocked preliminary without on ...

BACKGROUND Varus or valgus deviations of the femoral neck in osteogenesis imperfecta have been an ignored chapter because the classic correction procedures were applied in medical practice with unsatisfying results. Until the use of telescopic rods, coronal deviations remained unsolved and the distal configuration of the proximal femoral extremity remained uncorrected or partially corrected, wh...

Recently, there has been a trend towards high statistical indicators of the number bone fractures lower limbs(47.3%), which diaphyseal leg bones make up 45‒56 %. Objective. Conduct comparative analysisof stress-strain state models with fracture tibia under torsional loading combined various optionsof osteosynthesis and depending on patient's weight. Methods. A was modeled in middle third diaphy...
