Ultrasonographic and Clinical Characteristics of Schwannoma of the Hand.

Background: The purpose of this study was to report the ultrasonographic findings and clinical features of schwannoma of the hand.

Methods: We enrolled 8 patients who were initially diagnosed with ganglion by ultrasonography but finally with schwannoma by a tissue biopsy. We retrospectively analyzed the ultrasonographic findings of eight patients including echogenicity, internal homogeneity, posterior enhancement, internal vascularity, and clinical manifestations such as the occurrence site, tenderness, Tinel's sign, and paresthesia before the surgery.

Correlations of magnetic resonance imaging findings with clinical symptom severity and prognosis of frozen shoulder.

Purpose: To evaluate the correlation between indirect magnetic resonance (MR) arthrographic imaging findings and the clinical symptoms and prognosis of patients with frozen shoulder.

Methods: Indirect MR arthrography was performed for 52 patients with primary frozen shoulder (mean age 55.1 ± 9.

Total Limb Rotation after Unilateral Total Knee Arthroplasty: Side-to-Side Discrepancy.

Total limb rotation, an important anatomical feature of the lower limb, is defined as any rotation of the lower limb on its longitudinal axis. The aim of the present study was to evaluate the discrepancies of rotational profiles of total limb between nonoperated and operated limb following unilateral total knee arthroplasty. We conducted an analysis of the computed tomography (CT) data from 32 patients undergoing primary unilateral total knee arthroplasty.
