Abstract Objective  To determine the number of participants required in controlled clinical trials investigating the progression of osteoarthritis (OA) of the hip as evaluated by the joint space width (JSW) on radiographs and to evaluate the reproducibility of the JSW measurement methods. Materials and methods  Anteroposterior radiographs of hip were taken from 13 healthy volunteers and from 18 subjects with radiographic hip OA. The reproducibility of the JSW was determined from four segments using digital caliper measurements performed on film radiographs and using semiautomatic computerized image analysis of digitized images. Pearson correlation coefficient, coefficient of variability [CV (%)], and sample size values were calculated. Results  It was found that 20 was a typical number of patients for a sufficiently powered study. The highest sample size was found in subjects with OA in the lateral segment. The reproducibility of the semiautomatic computerized method was not significantly better than the digital caliper method. Conclusion  The number of study subjects required to detect a significant joint space narrowing in follow-up studies is influenced by the baseline hip joint OA severity. The JSW measurements with computerized image analysis did not improve the reproducibility and thus performing JSW measurements with a digital caliper is acceptable.

Abstract Purpose  To evaluate the clinical safety and effectiveness of foam sclerotherapy using polidocanol for the treatment of gastric fundal varices by balloon-occluded retrograde transvenous obliteration (BRTO). Materials and methods  From November 2005 to June 2009, foam sclerotherapy using polidocanol for the treatment of gastric fundal varices by BRTO was performed in 16 patients (male/female 11:5; age range 46–84 years, median 67 years). Foam was made of 3% polidocanol (Aethoxysklerol; Kreussler Pharma, Wiesbaden, Germany), room air, and contrast media, with a ratio of 1:2:1, respectively. The amount of polidocanol (2–24 mL; median 7 mL) depended on the volume of varices. Results  Technical success was achieved in 15 of 16 patients (93.8%). Technical failure occurred in one patient. All patients were without pain during sclerotherapy. One patient experienced pulmonary edema after the procedure but completely recovered with medical treatment. There was no procedure-related mortality. Patients were followed by endoscopy, computed tomography, or both. Four patients were lost to follow-up. Clinical success was achieved in 10 of 11 patients (91%). Rebleeding occurred in one case during follow-up. Conclusions  Foam sclerotherapy using polidocanol is clinically safe and effective for the treatment of gastric fundal varices during BRTO.

Abstract  Bioabsorbable interference screws are commonly used to secure the graft during anterior cruciate ligament (ACL) reconstruction, in part because they result in less image degradation on subsequent magnetic resonance imaging (MRI). However, some bioabsorbable screws are associated with abnormalities on MRI examination not reported with metallic interference screws. We describe a finding on knee MRI examination after ACL reconstruction using a polylactide carbonate (PLC) bioabsorbable screw that we believe to be previously unreported with any other bioabsorbable screws. The finding raised suspicion of hemorrhage or infection, neither of which were present clinically. Analysis of tissue from the tibial tunnel suggested an explanation for the MRI finding: calcite crystals. An additional five patients with knee MRI examinations after ACL reconstruction using a PLC screw were reviewed and correlated with clinical findings with four having similar imaging abnormalities present. The PLC (Calaxo screw, Smith and Nephew, Andover, MA) screw used in these patients has been recalled in the United States and Europe by the manufacturer after a greater than expected incidence of adverse reactions, and legal action may be pending.
