Limited Flexion of the Middle Finger Due to a Degenerative Partial Flexor Tendon Rupture Mimicking a Soft Tissue Tumor.

Atraumatic subcutaneous rupture of the finger flexor tendon of the hand and forearm is rare. Most sites of closed and subcutaneous ruptures of the finger flexor tendon are the tendon-bone insertion and musculotendinous junction, and an intratendinous lesion is unusual. We report the case of a 76-year-old female who presented to our department with a one-month history of a soft tissue mass and limited flexion of the left middle finger without trauma.

Patient-reported outcomes for cervical disease in end-stage renal disease patients: Propensity matching analysis using volunteer data.

Unlabelled: As the number of patients with end-stage renal disease (ESRD) has been increasing, the number of cervical spine surgeries for the patients with ESRD has also been increasing. The purpose is to identify the differences in cervical disease-specific patient-reported outcomes (PROs) between a healthy population and patients with ESRD, adjusting for subjects' age and physical activity.

Methods: The ESRD group included patients with ESRD who were treated with hemodialysis in our outpatient clinic and healthy volunteers were individuals who attended public health lectures.

New Predictive Index for Lumbar Paraspinal Muscle Degeneration Associated With Aging.

Study Design: A cross-sectional imaging study of paraspinal muscle degeneration using a new index for easy evaluation.

Objective: To examine the natural progression of age-related changes in the lumbar paraspinal muscles and to verify the validity of our new index for evaluating paraspinal muscle degenerationSUMMARY OF BACKGROUND DATA.: Measurement of paraspinal muscle morphology is an effective method for reflecting atrophy and fat infiltration, but it is complicated to perform.
