A radiological classification system for talocalcaneal coalition based on a multi-planar imaging study using CT and MRI.

Objective: To develop a radiological classification system for talocalcaneal coalition suitable for adults.

Methods And Materials: A retrospective review was performed on patients diagnosed with talocalcaneal coalition from July 2001 to November 2011. Based on the cartilaginous or bony nature, facet joint orientation and bony structure morphology, we classified talocalcaneal coalitions into four types: I (linear with or without posterior hooking), II (talar overgrowth), III (calcaneal overgrowth) and IV (complete osseous).

Comparison of arthroscopic and magnetic resonance imaging findings in osteochondral lesions of the talus.

Background: Magnetic resonance imaging (MRI) is widely used for diagnosing osteochondral lesions in the talus. The purpose of this study was to directly compare the MRI with the arthroscopic findings.

Materials And Methods: MR images of 42 ankles were retrospectively reviewed during a period of 67 months.

The MRI findings of meniscal root tear of the medial meniscus: emphasis on coronal, sagittal and axial images.

Purpose: The purpose of this study was to evaluate the accuracy of the characteristic magnetic resonance imaging (MRI) findings of medial meniscal root tear in the coronal, sagittal and axial planes.

Methods: Thirty arthroscopically diagnosed patients who had undergone preoperative knee MRI were included in this study. They were compared to 30 age-matched patients with medial meniscus tears without root tears.

Symptomatic torn discoid lateral meniscus in adults.

The purposes of this study were to report degenerative changes that coexist with a symptomatic torn discoid lateral meniscus in adults and to analyze the factors associated with the accompanied degenerative changes. From 1997 to 2008, 329 knees in the 305 patients were included. Associations between the status of the meniscus and the coexisting degenerative changes on the images and the arthroscopic findings were statistically analyzed.

Comparison of indirect isotropic MR arthrography and conventional MR arthrography of labral lesions and rotator cuff tears: a prospective study.

Objective: The purpose of our study was to prospectively compare the diagnostic accuracy of 3D isotropic indirect MR arthrography with conventional sequences of indirect MR arthrography for the diagnosis of labral and rotator cuff lesions on a 3-T MR unit.

Subjects And Methods: Thirty-six consecutive patients who were scheduled for shoulder arthroscopic surgery at our institution underwent indirect MR arthrography. Both conventional sequences and an additional 3D isotropic sequence were obtained 1 day before arthroscopic surgery.

Ethanol embolotherapy of pelvic arteriovenous malformations: an initial experience.

Objective: We retrospectively assessed the results of performing ethanol embolization for pelvis arteriovenous malformations (AVMs).

Materials And Methods: During the past 10 years, eight patients (8 females, age range: 27-52 years) with AVMs in the pelvic wall (n = 3) and uterus (n = 5) underwent staged ethanol embolizations (range: 1-5, mean: 2.5) under general anesthesia.
