Physicians reportedly obtain over 60 million computed tomography (CT) scans each year in the United States. However, a recent study in the New England Journal of Medicine (NEJM) suggests that CT scans may be linked to an increased risk of radiation exposure and cancer.
Citing evidence from epidemiologic studies, the authors of the NEJM article indicate that organ doses from a common CT study, consisting of two or three scans, may result in an increased risk of cancer.
“As compared with plain film radiography, CT invo

Dedicating oneself to the side of limb salvage in the fight against diabetic foot disease is a demanding and personally challenging enterprise. In the face of infection, it often seems as though all variables are against the surgeon and the patient as they both struggle against the possibilities of proximal amputation and limb loss. In fact, it often appears as though the only constant is the unpredictability of the disease progression.
However, expert knowledge in lower extremity anatomy is one of the most valuable tools that one can have in this fi

Treating a wound on a Charcot foot can be a challenge. Our expert panelists discuss the diagnosis of acute Charcot, the management of Charcot and Charcot-related wounds, indications for exostectomy and keys to facilitating a return to weightbearing.
Q: How do you diagnose an acute Charcot foot? Do you use any ancillary testing?
A: Most of the time, Geoffrey Habershaw, DPM, diagnoses acute Charcot by combining the patient’s history and physical with simple tests.
Dr. Habershaw, Lawrence Lavery, DP

Nonunion is a well-documented potential complication of the Lapidus arthrodesis. It reportedly occurs anywhere from 3.3 percent to 12 percent of the time, and is a very challenging problem to fix.1-7
Granted, a strict definition of nonunion and timeline for classifying a nonunion varies from one surgeon to another. However, for the purpose of this discussion, nonunion has both clinical and radiographic definitions. Nonunions involve the failure of bone healing at the fusion site after six months, broken hardware or both. A clinical nonunio
Soft tissue neoplasms of the lower extremity present a significant treatment challenge to the treating physician. Although most neoplasms of the lower extremity prove to be benign, the potential for malignancy does exist. The ability to appropriately diagnose and treat soft tissue neoplasms may be the difference between life and death for the patient presenting with a soft tissue tumor of the lower extremity.
Accordingly, let us take a closer look at appropriate evaluation and diagnostic techniques that will aid the physician in making an accurate dia
During the past five years, there has been a large influx of non-traditional bone screws on the orthopedic market for small bone fixation of the foot. Some of these designs have been effective at providing long-term surgical fracture stability with reduced osteotomy fixation morbidity. Additionally, these bone screw designs have found their way into a variety of applications in hindfoot surgery with headless screws, locking plate screws and cannulated self-tapping screws.
When trying to assess the technology available in small fragment fixation, it
