OBJECT To evaluate the efficacy of hybrid treatment combining emergency surgery and intraoperative interventional radiology (IVR) for severe trauma. PATIENTS AND METHODS The records of 63 severely injured patients who underwent concurrent emergency surgery and IVR at our emergency centre from 1999 through 2013 were retrospectively reviewed. Mobile digital(More)
PURPOSE In patients with unstable pelvic ring fractures, the factors related to poor outcome are still controversial. The purpose of our study was to evaluate the long-term functional outcome of patients with unstable pelvic ring fractures and correlate it with various other factors. METHODS Fifty-seven patients who had a minimal follow-up of 2 years(More)
Expression of cyclins A and E and cyclin-dependent kinase 2 (cdk2) was examined immunohistochemically in 55 cases of soft tissue smooth muscle tumors, including vascular leiomyoma, and compared to expression of Ki-67 and proliferating cell nuclear antigen. Cyclin A was expressed in 70% of the leiomyoma cases, but with much lower labeling indexes than in(More)
Osteoarthritis is characterized by marked osteophyte formation consisting of new cartilage and bone. Because several growth factors are known to be involved in chondrogenesis and osteogenesis, the expression of transforming growth factor-beta 1 and basic fibroblast growth factor in the osteophytes of the human femoral heads in osteoarthritis were examined.(More)
To clarify the distribution of bone-marrow-derived cells in fractures treated by plate fixation, fracture models were created using the green fluorescent protein (GFP) chimeric mouse. We observed 2 types of fracture healing processes with different types of callus formation and cellular events by using Mouse Fix™, a device allowing plate fixation on the(More)
This study aimed to clarify the relationship between the mechanical environment at the fracture site and endogenous fibroblast growth factor-2 (FGF-2). We compared two types of fracture healing with different callus formations and cellular events using MouseFix(TM) plate fixation systems for murine fracture models. Left femoral fractures were induced in 72(More)
STR/ort mice develop a naturally occurring osteoarthritis (OA) of the knee joints. However, the evaluation of early OA changes has been difficult due to variability caused by gender, individual differences, and differences between the right and left lower limbs. The objective of this study was to analyze the variability of the early OA changes with age in(More)
We report the status of bone allografting in Japan on the basis of the information obtained through questionnaires performed by the Japanese Orthopaedic Association (JOA). JOA performed a nation-wide survey in 2000, in order to clarify the current status of musculoskeletal tissue grafting in the orthopaedic practices in Japan. Conducted period was for 5(More)
Many investigators are currently studying the use of decellularized tissue allografts from human cadavers as scaffolds onto which patients’ cells could be seeded, or as carriers for genetically engineered cells to aid cell transplantation. However, it is difficult to seed cells onto very dense regular connective tissue which has few interstitial spaces.(More)
PURPOSE To study the anatomy of the pubic ramus and adjacent structures in 160 Japanese to establish a safer pubic screw fixation technique. METHODS 80 male and 80 female Japanese aged 16 to 89 (mean, 50) years (10 persons in each decade of age) underwent 3-dimensional computed tomographic scanning of their pelvises. The angle at which the screw should be(More)
