The Usefulness of Magnetic Resonance Imaging in the Diagnosis of Anterolateral Impingement of the Ankle

The purpose of this study is to assess the sensitivity and specificity of magnetic resonance imaging (MRI) in the diagnosis of anterolateral impingement of the ankle and to assess the most helpful sequence in making the diagnosis. Twenty-four patients who had undergone ankle arthroscopy were chosen. Twelve patients had arthroscopically documented anterolateral impingement, and 12 patients with no impingement on arthroscopy served as controls. Two musculoskeletal radiologists and an orthopedic surgeon, blinded to the operative diagnosis, retrospectively reviewed selective MRI images in the sagittal, axial, and coronal planes. The sensitivities and specificities were calculated for all 3 reviewers. The Kendall coefficient of concordance was calculated for overall agreement among reviewers. Sensitivities varied from 0.75 to 0.83, whereas specificities varied from 0.75 to 1.00. Using the Fisher exact test of contingency, the sensitivities and specificities showed that all reviewers' interpretations were statistically significant with P = .039, .001, and .012, respectively. The axial images were felt to be most helpful in making the diagnosis. The physicians felt that the sagittal images were helpful in 67%, 83%, and 100%, respectively. MRI is a useful tool that can aid the clinician in the diagnosis of anterolateral impingement of the ankle. T1 sagittal images demonstrating displacement of the normal fat signal anterior to the fibula by scar can be useful and help to confirm the diagnosis.     

Familial adenomatous polyposis (Gardner's syndrome) and thyroid carcinoma

Summary The case history of a 24-year-old woman with Gardner's syndrome [familial adenomatous polyposis (FAP)] and papillary thyroid carcinoma is presented, representing the 37th report of this association. Although FAP is transmitted as an autosomal dominant trait with similar penetrance in both sexes, thyroid carcinoma has been found almost exclusively in women (94.3%). The majority have been papillary carcinomas (88.5%), which have become apparent during the third decade (average 23.6, range 16–40 years). Most (55.5%) thyroid carcinomas have been discovered 1–17 years after FAP was identified, although some have been found before (29.6%), or at the same time (14.8%) FAP was diagnosed. Multicentric papillary carcinomas have been reported in 64% (14 of 22) of FAP patients, a frequency at least twofold greater than usual. Although papillary carcinoma found before age 30 (as it was in most patients with FAP) typically has an excellent prognosis, one patient with FAP developed distant metastases from thyroid carcinoma and a 28-year-old woman's death was attributed to papillary carcinoma. The high frequency of multicentric papillary thyroid carcinoma in young patients with FAP and the potential for metastases and death due to thyroid carcinoma warrant aggressive diagnostic screening at regular intervals with neck palpation, ultrasonography, and if necessary, fineneedle aspiration biopsy. When thyroid carcinoma is found, total or near-total thyroidectomy should be considered because of the tumor's high likelihood of being multifocal. Since almost 30% of the thyroid carcinomas associated with FAP have been diagnosed 4–12 years before polyposis was identified, young patients presenting with thyroid carcinoma should be questioned regarding bowel function and a family history of gastrointestinal disease, and consideration should be given to periodic testing for fecal occult blood.The views expressed herein are those of the authors and do not necessarily reflect those of the Army or the Department of Defense.     

A Novel Digital Tourniquet Using a Sterile Glove and Hemostat

Background. Surgery of the digit is facilitated with adequate hemostasis for visualization of the operative field. Several types of tourniquets have been used for this purpose, including glove fingers, Penrose drains, Marmed digital tourniquets, and standard pneumatic tourniquets.
Objective. To present a novel method to achieve hemostasis during surgery of the digit.
Materials. A slightly oversized sterile glove, a hemostat, and a pair of scissors.
Conclusion. We present a novel method to achieve hemostasis using a sterile glove and a hemostat, that allows the surgeon to methodically titrate the amount of compression necessary to attain a bloodless field while minimizing the risks of excessive pressures.

Common sense in the treatment of pilonidal disease

Summary The management of pilonidal cyst disease in a large military hospital is described. Of special interest to the military practice is the “buddy” system, in which patients help one another to keep their wounds clean and dry. The specific objectives of our technic are: 1) obtaining excellent hemostasis by the use of zinc peroxide paste; 2) avoiding recurrences by an open-wound method of treatment; 3) preservation of a pad of subcutaneous tissue over the postsacral fascia, thus reducing long-term morbidity by insuring a mobile scar; 4) decreasing the duration of hospitalization, achieved by frequently drying the wounds with warm air.
