Healing Effect of Subcutaneous Administration of Granulocyte Colony-Stimulating Factor on Acute Rotator Cuff Injury in a Rat Model.

Granulocyte colony-stimulating factor (G-CSF) is a cytokine that mobilizes bone marrow-derived cells (BMDCs) to peripheral blood and has been clinically used to treat neutropenia. Previously, we reported that BMDCs migrated into the rotator cuff repair site via peripheral blood in the healing process. However, techniques to accelerate the healing process using the peripheral blood pathway have not been established.

Cryptococcal Osteomyelitis of the Entire Humerus: A Case Report.

Case: We describe a case of cryptococcal osteomyelitis in a 70-year-old man who presented with left elbow and shoulder pain. Subsequent imaging indicated osteomyelitis of the entire humerus, and he underwent debridement of the elbow and shoulder. Pathological findings revealed Cryptococcus neoformans infection.

Intracerebral hemorrhage due to cerebral venous thrombosis during posterior cervical decompression and fusion for traumatic cervical cord injury: A case report.

Rationale: Cerebral venous thrombosis (CVT) is a cerebrovascular disorder that causes venous infarction and intracerebral hemorrhage (ICH) with occlusion of cerebral veins, and its incidence is estimated to be 5 per 1 million people per year, accounting for 0.5% to 1.0% of all strokes.

Early detection of osteoarthritis in rabbits using MRI with a double-contrast agent.

Background: Articular cartilage degeneration has been evaluated by magnetic resonance imaging (MRI). However, this method has several problems, including its time-consuming nature and the requirement of a high magnetic field or specialized hardware. The purpose of this study was to sequentially assess early degenerative changes in rabbit knee articular cartilage using MRI with a new double-contrast agent.

Therapeutic outcomes of muscular advancement by an arthroscopic-assisted modified Debeyre-Patte procedure for irreparable large and massive rotator cuff tears.

Background: In cases of the large or massive rotator cuff tears, retear rates after rotator cuff repairs remain high. We introduced an arthroscopic-assisted modified Debeyre-Patte procedure which enables to decrease the tension of torn rotator cuff by sliding supraspinatus and infraspinatus laterally keeping fascia connection to the rhomboids.

Purpose: The objective of this study was to examine the clinical outcomes and retear rates after an arthroscopic-assisted modified Debeyre-Patte procedure for irreparable large and massive rotator cuff tears.

Validity of radial magnetic resonance imaging to determine the extent of Bankart lesions.

Purpose: The objectives were to compare conventional oblique coronal and axial images with radial images to determine the capacities of these modalities for visualizing sites in the glenoid labrum.

Materials And Methods: The glenoid labra of 45 patients without a labrum injury and 30 patients with Bankart lesions were examined by magnetic resonance imaging using three different sections.

Results: The radial images permitted a greater range of assessment of the morphology of the glenoid labrum than the conventional images.

Stimulation of Rotator Cuff Repair by Sustained Release of Bone Morphogenetic Protein-7 Using a Gelatin Hydrogel Sheet.

Bone morphogenetic protein-7 (BMP-7) promotes not only osteogenesis but also matrix production in chondrocytes and tenocytes. However, because of its short half-life, maintaining local concentrations of BMP-7 is difficult. We examined the use of a gelatin hydrogel sheet (GHS) for the sustained release of BMP-7 in stimulating rotator cuff repair at the tendon-to-bone insertion.
