BACKGROUND This study evaluated the application of a layered cell free poly (L-lactic acid) (PLLA) scaffold to regenerate an infraspinatus tendon defect in a rabbit model. We hypothesized that PLLA scaffold without cultivated cells would lead to regeneration of tissue with mechanical properties similar to reattached infraspinatus without tendon defects. (More)
An 83-year-old woman, subsequently diagnosed with Parkinson's disease, fell on her right shoulder. Radiographs showed the humeral head dislocated anterosuperiorly. The supraspinatus tendon was massively disrupted and judged irreparable. The subscapularis tendon was repaired, however re-dislocation of the humeral head was confirmed after the surgery but(More)
BACKGROUND It is important to regenerate the tendon-to-bone interface after rotator cuff repair to prevent re-tears. The cells from torn human rotator cuff were targeted, and their capacity for multilineage differentiation was investigated. METHODS The edges of the rotator cuff were harvested during arthroscopic rotator cuff repair from nine patients,(More)
PURPOSE The PainVision™ system was recently developed for quantitative pain assessment. Here, we used this system to evaluate the effect of plexus brachialis block on postoperative pain after arthroscopic rotator cuff repair. METHODS Fifty-five patients who underwent arthroscopic rotator cuff repair were included in this study. First 26 cases received no(More)
INTRODUCTION Anatomical abnormalities in the lower limb vessels are uncommon. However, the preoperative evaluation of the anatomical variations is very important for planning the operation procedure to prevent jeopardizing the donor leg. CASE PRESENTATION In this case report, a 23-year-old Asian woman who was scheduled to have vascularized free fibula(More)
INTRODUCTION Some patients showed unusual responses to the immobilization without any objective findings with casts in upper extremities. We hypothesized their that intolerance with excessive anxiety to casts is due to claustrophobia triggered by cast immobilization. The aim of this study is to analyze the relevance of cast immobilization to the feeling of(More)
In children, flexor pollicis longus (FPL) tendon injuries are uncommon. In delayed diagnosed cases, CT and MRI are hard to perform, even though to confirm the location of the lacerated proximal tendon end is preferable for the planning of operation procedure. In such condition, ultrasonography is suitable because of its characteristic feature of(More)
Advanced carpal tunnel syndrome presents severe thenar atrophy with the absence of electrophysiological motor and sensory responses. Because of severity of these conditions, a substantial period of recovery after surgery is required before improvement becomes evident. In this electrophysiological-based study, the reappearance of distal motor latency (DML)(More)
A case presented dysfunctional flexion of the thumb and index fingers after volar plate fixation for of distal radius fractures was diagnosed anterior interosseous nerve palsy and confirmed by 3D-CT. 3D-CT was useful to confirm the continuities of tendons, which excluded the most common complication of tendon ruptures after volar plate fixation. Also, it(More)
We present a case of arthroscopic fixation for bony Bankart lesion using a double-threaded cannulated screw. A 39-year-old man sustained a left shoulder injury from a motorcycle accident. Radiographs showed bony Bankart lesion and CT revealed 40% defect of glenoid articular surface. Arthroscopic fixation was performed using double-threaded cannulated screw(More)
