PURPOSE To develop objective criteria for the ultrasonographic (US) appearance of the triangular cord (TC) sign for the diagnosis of biliary atresia. MATERIALS AND METHODS US was performed in 86 infants with jaundice. Biliary atresia (n = 20) was confirmed with hepatoportoenterostomy. Neonatal hepatitis (n = 66) was diagnosed with needle biopsy (n = 5),(More)
OBJECTIVES To assess the ultrasonographic findings and to evaluate the value of ultrasonography as a diagnostic method for detecting clinical medial epicondylitis. DESIGN A prospective, single-blind study. SETTING An outpatient rehabilitation clinic in a tertiary university hospital. PARTICIPANTS Twenty-one elbows from 18 patients with clinical medial(More)
OBJECTIVE To evaluate the diagnostic value of ultrasonography in meniscal tears that were diagnosed by magnetic resonance imaging (MRI). DESIGN Twenty-seven knees with meniscal tears and 14 knees without tears on MRI were prospectively evaluated. A radiologist performed the ultrasonography and evaluated the presence and locations of the meniscal tears.(More)
BACKGROUND To evaluate the sonographic findings of soft-tissue nonsubungual glomus tumors. METHODS The sonographic appearances of nine histologically proven soft-tissue glomus tumors of nonsubungual location in nine patients (mean age, 49 years; M:F = 7:2) were reviewed retrospectively. Doppler examination and surgical excision were performed in all(More)
Because there is no consensus regarding the factors predicting femoral head collapse in asymptomatic osteonecrosis of the hip, we studied the risk factors for collapse. Between 1990 and 2000, we used MRI to confirm asymptomatic osteonecrosis of the femoral head in 81 patients (81 hips) whose other hip had nontraumatic symptomatic osteonecrosis and we(More)
OBJECTIVE To report and assess the usefulness of ultrasound (US) findings for occult fractures of growing bones. MATERIALS AND METHODS For six years, US scans were performed in children younger than 15 years who were referred with trauma-related local pain and swelling of the extremities. As a routine US examination, the soft tissue, bones, and adjacent(More)
To describe ultrasound findings of Kimura’s disease arising in the upper extremities. Five patients with Kimura’s disease confirmed by surgical resection were retrospectively reviewed by two musculoskeletal radiologists and a pathologist. All six lesions involved the epitrochlear area and appeared as partially (n = 5) or poorly (n = 1) marginated(More)
BACKGROUND The aim of this study was to describe the mini-open suture bridge technique with porcine dermal patch augmentation for massive rotator cuff tear and to assess preliminary clinical and radiological results. METHODS Five patients with massive rotator cuff tear for which it was not possible to restore the anatomical footprint underwent mini-open(More)
OBJECTIVE To evaluate and compare the morphologic changes of the ulnar nerve at the elbow, using ultrasonography, between patients with cubital tunnel syndrome and retrocondylar compression syndrome determined with electrodiagnosis. DESIGN Prospective study using electrodiagnosis and ultrasonography. SETTING An outpatient rehabilitation clinic in a(More)
