Athletic injuries of the lower extremities are commonly encountered in clinical practice. While some pathology can be diagnosed on physical exam, others are a clinical dilemma with nonspecific symptomatology. In these situations, ultrasound imaging can be utilized as an exceptional diagnostic tool, offering unique advantages over other imaging modalities. This article will review the imaging characteristics of commonly encountered athletic injuries of the lower extremity.

We report the imaging findings in a case of fetal lymphangioma involving the retroperitoneum and right lower extremity, and diagnosed by ultrasonography and magnetic resonance (MR) imaging at 26 weeks of gestation. Prenatal ultrasonograms and T2-weighted single-shot fast spin-echo MR images clearly revealed an extensive, multilocular cystic mass with internal hemorrhage in the retroperitoneum extending to the lower extremity.

BACKGROUND: The aim of this study is to evaluation of lower extremity with doppler ultrasonography in the thrombotic poststroke patients. METHOD: The subjects were 24 thrombotic poststroke patients. We analyzed the stenosis or obstruction in the lower extremity artery with a doppler ultrasound and the cerebral artery with a magnetic resonance angiography. RESULTS: In the lower extremity artery, 3 patients had the complete obstruction in one and more vessels, 7 patients had the luminal narrowing more than 50% in one and more vessels, 11 patients had the luminal narrowing less than 50% in one and more vessels. And in the cerebral artery, 9 patients had the Obstruction or stenosis of the artery without diffuse atherosclerosis, 15 patients had the arterial obstruction or stenosis with diffuse atherosclerosis, or multiple arterial pathology. CONCLUSION: In this study, poststroke patients with arterial obstruction or stenosis with diffuse atherosclerosis in the cerebral artery had more severe atherosclerotic change in the lower extremity(p<0.05). We recommended to the evaluation of a doppler ultrasound of lower extremity in the thrombotic poststroke patients with diffuse atherosclerotic change of the cerebral artery.

The purpose of this study was to determine shoulder pain and shoulder ultrasonographic findings in poliomyelitis Wheelchair Basketball (WB) players. Three physicians performed physical examinations and interviewed WB players about their shoulder pain by using Wheelchair User's Shoulder Pain Index (WUSPI), Performance-Corrected WUSPI (PC-WUSPI), and Shoulder Pain and Disability Index (SPADI). One physician performed shoulder ultrasonography on WB players. All confirmed their International Wheelchair Basketball Federation (IWBF) classifications through Korean Wheelchair Basketball Federation (KWBF). Seventeen men and 6 women players were enrolled in the study, with 46 shoulders evaluated. Nine players had unilateral lower extremity weakness and 14 players were bilateral weakness. Six players used wheelchair for daily living, and 17 players used wheelchair only when playing WB. They were 44.35+/-5.42 years old on average. They had played WB for 11.09+/-9.49 years and trained 8.69+/-3.83 hours a week. PC-WUSPI was significantly correlated with age (p=0.014). There were no significant differences between time spent playing WB, training time for WB, types of poliomyelitis involvement, their use of wheelchair, and WUSPI, PC-WUSPI and SPADI. Tendon tear prevalence was significantly different with training time for WB (p=0.021). Most common abnormal shoulder ultrasonographic findings were subscapularis and supraspinatus tendinopathy. Tendinopathy and tendon tear prevalence did not differ significantly with age, time spent playing WB, types of poliomyelitis, and the use of wheelchair. High prevalence of shoulder pain and rotator cuff pathology were found by physical and ultrasonographic examination in the poliomyelitis wheelchair basketball players. Rotator cuff injury prevention program are needed for prevent shoulder pain and rotator cuff pathology.

OBJECTIVETo observe the effect of Tongmai Recipe (TMR) on atherosclerosis (AS) in patients with early lower extremity arteriopathy disease (LEAD) caused by type 2 diabetes mellitus (T2DM).

METHODSPatients were randomly assigned to two groups. The 23 patients in the treatment group were treated by TMR and the 22 in the control group were given Cilostazo, all for 3 months. Before and after treatment, lower extremity vascular color Doppler image, blood levels of glucose, insulin, serum matrix metalloproteinase-9 (MMP-9) and interleukin-6 (IL-6) were measured.

RESULTSThe thickness of AS plaque and that of arterial intima-media obviously reduced (P < 0.01 and P < 0.05), insulin sensitivity improved noticeably (P < 0.01), and serum levels of MMP-9 and IL-6 lowered obviously (P < 0.05) in the treatment group after treatment, but these indexes were unchanged in the control group statistically.

CONCLUSIONTMR has remarkable action in reducing the thickness of AS plaque and intima-media of artery, its mechanism might be related with improving of insulin sensitivity and anti-inflammatory reaction, and reducing of serum MMP-9 level as well in patients.
