patients and methods the study population consisted of all patients with type iiia gastilo open fractures of tibial shaft, with or without fibula fracture (caused by trauma). after wound irrigation, debridement, and wound swab sampling for microbial culture, all patients received prophylactic antibiotic regimens in fitting with their wound class. no topical antibiotics were used with a 6-month ...

During colonoscopy, looping of the colonoscope shaft is considered one of the biggest challenges of the procedure. It hinders the advancement of the distal tip of the colonoscope requiring time to retract and straighten the shaft. Consequently, anesthesia exposure and operative time, and associated risk and cost are all increased. Many active and passive auxiliary devices have been introduced t...

INTRODUCTION Diaphyseal fractures of both bones of the forearm are commonly encountered in clinical practice. Segmental radius shaft fractures are, however, less commonly seen. We hereby report two cases of segmental complex radius fracture with mid-shaft ulna fracture. Such type of cases are reported previously in children but rarely in adults. CASE REPORT In case-1, comminuted radius shaft ...

INTRODUCTION The objective of this study was to assess three-dimensional bone geometry and density at the epiphysis and shaft of the third meta-carpal bone of rheumatoid arthritis (RA) patients in comparison to healthy controls with the novel method of peripheral quantitative computed tomography (pQCT). METHODS PQCT scans were performed in 50 female RA patients and 100 healthy female controls...

We report five cases of intertrochanteric fractures that needed open reduction after failed closed reduction techniques. In all cases the shaft fragment included the lesser trochanter, and there was a long spike on the head-neck fragment. This was evident clinically as the proximal shaft, pulled by the iliopsoas tendon, produced a swelling in front of the hip joint. Radiographically, the fractu...

Adenoviral (Ad) vectors have been widely used in human gene therapy clinical trials. However, their application has frequently been restricted by the unfavorable expression of cell surface receptors critical for Ad infection. Infections by Ad2 and Ad5 are largely regulated by the elongated fiber protein that mediates its attachment to a cell surface receptor, coxsackie and adenovirus receptor (...

Selection of shaft geometry is critical to the overall performance of a rotary compressor. Consideration is given to the development of rotary compressor shaft geometries to optimize efficiency and reliability. The cylinder to piston dynamic clearance is of prime importance with respect to leakage losses. An analysis of bearing film thicknesses and shaft deflection was conducted to fully evalua...

A novel application, employing the strategy of Active Disturbance Rejection Control and an Extended State Observer, is proposed to control the rotor shaft position of NASA’s High Speed Shaft (HSS) Flywheel using active magnetic bearings. The robustness of the control is demonstrated in a frequency domain analysis and in simulations to be a major improvement of controls recently studied at NASA.

Patients and Methods: From April 2009 to January 2014, we treated 91 patients with high-energy fractures of the tibial shaft at Orthopedic Department of AlRamadi Teaching Hospital. Twenty patients were suitable for our study that had closed segmental fractures of tibial shaft (42-C2 / AO classification), treated by minimal, internal and external, fixations with follow up range from 6 months to ...
