Popliteal Artery Thrombosis After Open Reduction and Internal Fixation of the Patella: A Case Report.

Case: A 31-year-old man presented with a right patellar fracture after a motor-vehicle accident. He had a history of a myocardial infarction and cerebrovascular accident, for which he reported taking aspirin and clopidogrel daily. One hour after surgery, an acute popliteal artery thrombosis was detected.

Effect of initial postoperative visit radiographs on treatment plans.

Background: It is a common practice among orthopaedic surgeons to make radiographs at the first outpatient postoperative visit after surgical repair of acute fractures. There is not much literature that investigates the benefits and necessity of such a practice. We hypothesized that the practice of routine postoperative radiographs is unnecessary and increases cost to the patients and the health-care system, increases radiation exposure, and provides no change in patient management.

Mechanical evaluation of large-size fourth-generation composite femur and tibia models.

Composite analogue bone models provide consistent geometric and structural properties that represent a valuable asset in a range of biomechanical analyses and testing procedures. The objective of this study was to evaluate the diaphyseal structural properties of the large-size Fourth-Generation composite analogue femur and tibia models concentrated on mechanical behaviors under axial compression, bending and torsion. Thirty of each large-size composite analogue models (femora and tibiae) were tested under medial-lateral four-point bending, anterior-posterior four-point bending, axial compression and external rotational torque to evaluate flexural rigidity, axial stiffness, torsional rigidity and ultimate failure strength.
