Is Bridge Plating of Comminuted Humeral Shaft Fractures Advantageous When Using Compression Plates with Three versus Two Screws per Fragment? A Biomechanical Cadaveric Study.

Background: Minimally invasive plate osteosynthesis (MIPO) is one of the generally accepted surgical techniques for the treatment of humeral shaft fractures. However, despite the high bone union rate, a variety of complications are still prevailing. Moreover, the current literature lacks data comparing the anterolateral MIPO approach using dynamic compression plates accommodating different numbers of screws.

Publication rates of papers presented at the Brazilian Orthopedic Meeting.

Objective: To quantify the publication rates of the papers presented at the 2007 Brazilian Orthopedics Meeting (Congresso Brasileiro de Ortopedia - CBOT).

Methods: Evaluation of the proportion of abstracts submitted by the various orthopedic subspecialties and according to the Brazilian states. Then, a Lilacs and PubMed search was performed in order to determine which presentations generated national or international published papers.

Reversible pulmonary trunk banding: VII. Stress echocardiographic assessment of rapid ventricular hypertrophy in young goats.

Background: Ventricle retraining with abrupt systolic overload can cause myocardial edema and necrosis, followed by late ventricular failure. Intermittent systolic overload could minimize the inadequacy of conventional pulmonary artery banding. The present study compared ventricle function under dobutamine stress in 2 protocols of systolic overload in young goats.

Intermittent systolic overload promotes better myocardial performance in adult animals.

Background: Corrected transposition of great arteries often evolves with right ventricular dysfunction. The ventricular preparation for anatomic correction in adult patients has produced disappointing results.

Objective: To assess right ventricular hypertrophy (RV) induced by conventional and intermittent pulmonary banding (PB) in adult animals.
