AIM To confirm whether implanting pedicle-screw at the level of fractured vertebra increases adverse effects on fracture healing. MATERIAL AND METHODS CT follow-up was conducted for 28 patients who sustained thoracic or lumbar burst fracture and underwent posterior pedicle-screw instrumentation and reduction including implanting screws into the fractured vertebra at the same time. The time fo...
A pilot study has shown that there is usually but not invariably a fall in systemic arterial blood pressure within 90 seconds of implanting acrylic cement into the femoral shaft during hip arthroplasty. There is usually no change in arterial blood pressure on implanting acrylic cement into the acetabulum. The observed hypotension may be due to absorption of monomer or additives into the circula...
In the present study, we compared the effects of implanting peripheral sensory nerve and motor nerve on motoneuron survival and regeneration after spinal root avulsion in adult rats. Our results showed that 116% more motoneurons regenerated axons into the motor than the sensory nerve graft and 59% of motoneurons survived in the motor nerve-implanted group compared to 48% in the sensory nerve-im...
The treatment of diseased vasculature remains challenging, in part because of the difficulty in implanting drug-eluting devices without subjecting vessels to damaging mechanical forces. Implanting materials using adhesive forces could overcome this challenge, but materials have previously not been shown to durably adhere to intact endothelium under blood flow. Marine mussels secrete strong unde...
An 81-year-old female was referred for cochlear implantation due to difficulty communicating in her daily activities despite the use of appropriate amplification. The poorer ear was unable to tolerate amplification for the past 15 years. The open-set sentence-recognition test score in quiet in her "good" ear was 85 percent correct, indicating that the patient was not a traditional cochlear impl...
To compare the different effects of implanting sensory nerve tracts or blood vessel on the osteogenesis, vascularization, and neurotization of the tissue-engineered bone in vivo, we constructed the tissue engineered bone and implanted the sensory nerve tracts (group SN), blood vessel (group VB), or nothing (group Blank) to the side channel of the bone graft to repair the femur defect in the rab...
