An Expedited Fracture Severity Metric for Post-traumatic OA Risk Assessment
ثبت نشده
چکیده
INTRODUCTION Post-traumatic osteoarthritis (PTOA) is the unfortunate outcome of many high-energy fractures of the tibial plafond. The severity of the fracture is a major risk determinant. The inability to objectively quantify fracture severity has confounded efforts to determine the efficacy of different treatments aimed at preventing the PTOA development. A CTbased measure of fracture energy was recently found to strongly predict PTOA (as reflected by the Kellgren-Lawrence (KL) radiographic score) within the first two years after a tibial plafond fracture [1]. But, the extensive time required to obtain the fracture energy metric (8-10 hours per case) precluded its use in busy clinical settings. The objective of this study was to establish that an expedited fracture severity metric based upon CT image texture analysis could provide comparable PTOA predictive ability as fracture energy, but in a fraction of the time.

Evaluation of Radiocapitellar Arthritis in Patients with a Second Radiograph at Least 2 Years after Nonoperative Treatment of an Isolated Radial Head Fracture
Background: To study if patients that have a second radiograph 2 or more years after nonoperative treatment of an isolated radial head fracture have radiocapitellar osteoarthritis (RC OA). Methods: We used the database of 3 academic hospitals in one health system from 1988 to 2013 to find patients with isolated radial head fractures (no associated ligament injury or fracture) that had a second ...

Patients with tibial pilon fractures have a higher incidence of post-traumatic osteoarthritis than those with fractures of the tibial plateau. This may indicate that pilon fractures present a greater mechanical insult to the joint than do plateau fractures. We tested the hypothesis that fracture energy and articular fracture edge length, two independent indicators of severity, are higher in...

Management of first shoulder dislocation following reduction remains controversial. The two main options are immobilisation and arthroscopic stabilisation. The aim of this article is to highlight some of the issues that influence decision making when discussing management options with these patients, including natural history of the first time dislocation, outcomes of surgery and non-operati...

OBJECTIVES To determine whether the presence and severity of post-traumatic vomiting can predict the risk of a skull vault fracture in adults and children. METHODS Data were analysed relating to a consecutive series of 5416 patients including children who presented to an emergency service in the United Kingdom during a 1 year study period with a principal diagnosis of head injury. Characteris...
