CT with multiplanar reconstruction gives new perspective on complex ankle fractures

02.11.2004


CT with multiplanar reconstruction provides a clear multi-dimensional view of tibial triplane fractures of the ankle--a view that alters what is found in many medical textbooks and changes the way physicians understand these complex fractures, a new study shows.



The study included 51 young people, ranging in age from 10 to 17 years old. Triplane fractures, (fracture lines occur in three planes of the ankle) account for about 6%-10% of ankle fractures in young people, says Stephen D. Brown, MD, instructor in radiology at Harvard Medical School in Boston. They are generally sports-related injuries, he added.

All 51 cases showed bone separation along the front part of the growth plate of the tibia. There were 33 "classic" two-fragment fractures as seen in medical textbooks, but the "classic" three fragment fracture (which involves a separation at Kump’s bump) "was not seen in this series," said Dr. Brown, lead author of the study. Three fragment fractures were seen, but they involved different fracture patterns than what has been previously described as most common, said Dr. Brown. In fact, the study found that fully half of the triplane fracture patterns described in the literature – some of which have been described as quite common - likely occur only very rarely or never at all. This is explained by the characteristic pattern of closure of the growth plate. In addition, "the medial malleolar variety of triplane fracture previously considered rare, was very common," he said. "In one-fourth of the patients in our cohort, fractures involved the medial malleolus, but spared the plafond," he said.


This new information clarifies the anatomy of these complex multidimensional fractures allows physicians to describe these fractures more uniformly, and will help facilitate the partnership between radiologists who diagnose these fractures and the orthopedic surgeons who treat them, Dr. Brown said. The study proposes using a common classification scheme – the Salter-Harris system – to help describe the appearance of these fractures in each different dimension as depicted by CT with multiplanar reconstruction.

"This is the largest published series on these types of fractures to date, and is the first one in which all fractures were imaged and analyzed using multiplanar CT," said Dr. Brown. The study is published in the November issue of the American Journal of Roentgenology.

Im Focus: Abrupt motion sharpens x-ray pulses

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.

A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...

Im Focus: Physicists Design Ultrafocused Pulses

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.

Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
