Posterolateral Corner Injury Associated with a Schatzker Type 2 Tibial Plateau Fracture.

Isolated posterolateral corner (PLC) injuries are rarely seen with tibial plateau fractures and can be missed during the initial assessment. The objective of this paper is to present a case of a Schatzker type 2 tibial plateau fracture with associated isolated PLC injury and give a discussion on physical exam, diagnostic studies, and treatment options. A twenty-five-year-old female sustained a concomitant Schatzker type 2 fracture and PLC injury.

Obese and diabetic KKAy mice show increased mortality but improved cardiac function following myocardial infarction.

Background: Introduction of the yellow obese gene (A(y)) into mice (KKAy) results in obesity and diabetes by 5 weeks of age.

Methods: Using this model of type 2 diabetes, we evaluated male and female 6- to 8-month-old wild-type (WT, n=10) and KKAy (n=22) mice subjected to myocardial infarction (MI) and sacrificed at day (d) 7.

Results: Despite similar infarct sizes (50% ± 4% for WT and 49% ± 2% for KKAy, P=not significant), the 7d post-MI survival was 70% (n=7/10) in WT mice and 45% (n=10/22) in KKAy mice (P<.
