Migration of wires or pins around the shoulder is a known complication, though their migration within the chest is uncommon. We report an unusual case of hydropneumothorax due to migration of a bent Kirschner wire from the right proximal humerus in a 63 year-old man. We reviewed his clinical history, physical examination, imaging findings, surgical method and outcome. We also reviewed the liter...

We report a technical modification of the classic transmanubrial osteomuscular sparing approach described by Grünenwald and Spaggiari for the treatment of a T1 vertebral tumor. The goal of the surgical treatment for spinal tumors of the cervico-thoracic area is to excise the vertebral tumor, reconstruct the spinal column, and place an internal fixation device to achieve immediate stabilization....

Background Surgical site infections (SSI) are the common nosocomial infection in surgical patients, and are a significant source of postoperative morbidity resulting in increased hospital stay, morbidity and cost. Objective The objective of this study was to obtain the incidence of SSI and determine various risks factors influencing the SSI rate with special reference to the National Nosocomial...

OBJECTIVE The Disease Activity Score including 28 joints (DAS28) and the Clinical Disease Activity Index (CDAI) were developed in order to provide a quantifiable measure of rheumatoid arthritis (RA) activity. The aim of this study was to evaluate the validity and internal consistency reliability for DAS28 and CDAI in patients with RA seen by rheumatologists in usual clinical care. We also compa...

Implant-associated infections and non-absorbing materials are two important reasons for a second surgical procedure to remove internal fixation devices after an orthopedic internal fixation surgery. The objective of this study was to produce an antibacterial and absorbable fixation screw by adding gentamicin to silk-based materials. The antibacterial activity was assessed against Staphylococcus...

Background: The aim of this article is to introduce a novel technique of limited dynamic hip screw (LDHS) in the treatment of intertrochanteric fractures and to evaluate its biomechanical effects. Material/Methods: Based on the principle of providing both dynamic and static pressure to stabilize the fracture, we improved the dynamic hip screw (DHS) and designed the LDHS. Six fresh cadavers were...

Introduction Posteriorly dislocated humeral head fracture has a great implication, as it is associated with high risk of avascular necrosis, limited access through the deltopectoral approach, and posterior approach to the posteriorly dislocated humeral fracture increases the risk to the remaining blood supply. Technical Tip Posteriorly dislocated humeral fracture is approached through deltope...

A rapid, simple, and specific method based on ultra performance liquid chromatography (UPLC) with mass spectrometry detection has been developed for quantitative analysis of ofloxacin in human aqueous humor using tobramycin as internal standard (IS). Chromatographic separation was achieved on a Waters Acquity UPLC BEH C18 Shield column (150 × 2.1 mm, 1.7 μm) eluted with 95:5 water: acetonitrile...

All-oxide-based photovoltaics (PVs) encompass the potential for extremely low cost solar cells, provided they can obtain an order of magnitude improvement in their power conversion efficiencies. To achieve this goal, we perform a combinatorial materials study of metal oxide based light absorbers, charge transporters, junctions between them, and PV devices. Here we report the development of a co...

INTRODUCTION Artificial models can be useful at approximate and qualitative research, which should give the preliminary results. Artificial models are usually made of photo-elastic plastic e.g.. juvidur, araldite in the three-dimensional contour shape of the bone. Anatomical preparations consist of the same heterogeneous, structural materials with extremely anisotropic and unequal highly elasti...
