purpose: to evaluate the outcomes of keratorefractive surgery for correction of postkeratoplasty astigmatism in keratoconus. methods: in this retrospective study, surgical records of 45 eyes of 45 patients that underwent relaxing incisions with or without compressive sutures were evaluated. the minimum interval between complete suture removal and operation was 1 month. location and extent of in...

Biceps tenodesis maintains the cosmetic appearance and length-tension relationship of the biceps with an associated predictable clinical outcome compared with tenotomy. Arthroscopic suprapectoral techniques are being developed to avoid the disadvantages of the open subpectoral approach. This study biomechanically compared 3 arthroscopic suprapectoral biceps tenodesis techniques performed with a...

INTRODUCTION One of the most dramatic conditions in obstetrics is definitely bleeding from the uterus which fails to compress. This condition is known as postpartum atony. When such a condition is diagnosed, the obstetrician has a choice of several conservative methods to stimulate the uterus to contract and several surgical methods to stop the bleeding. The most extreme measure used to save th...

Postpartum hemorrhage (PPH) is a life-threatening complication of delivery. It is the leading cause of maternal mortality. During the last 15 years, several total uterine compressive sutures were described in literature. They have proven their effectiveness and safety in the management of severe PPH as an alternative to hysterectomy. We present in this paper a new technique of uterine compressi...

The purpose of this study was to test the hypothesis that increased masticatory muscle accompanied morphologic changes in the temporal bone and squamosal suture. Ten mice deficient for the protein myostatin (Mstn -/-) had significantly increased skeletal muscle mass and were compared with nine controls (Mstn +/+). Variables measured include linear and areal metrics describing temporal size and ...

We report a very rare case of cervical compressive myelopathy by an anomalous bilateral vertebral artery (VA) entering the spinal canal at the C1 level and compressing the spinal cord. A 70-year-old woman had been suffering from progressive gait disturbance. Magnetic resonance imaging revealed that a bilateral VA at the V4 segment had abnormal courses and caused compression to the high cervical...

The failure of the pancreaticojejunal anastomosis remains an important and potentially lethal postoperative complication after pancreaticoduodenectomy. During the pancreaticojejunostomy, creation of compressive and shear forces during suture placement and knot tying may cause deformation of and cutting through the fragile pancreatic parenchyma. We sought to understand the mechanics of needle-pa...

Cranial vault and facial sutures interpose between mineralized bones of the skull, and may function analogously to appendicular and cranial base growth plates. However, unlike growth plates that are composed of chondrocyte lineage, cranial and facial sutures possess heterogeneous cell lineages such as mesenchymal cells, fibroblasts, and osteoblasts, in addition to vascular-derived cells. Despit...

The author describes barbed sutures as a unique wound closure tool. Their advantages include the closure of wounds without any knots or the need for a third hand. They are also capable of shifting tissues differentially along the suture to redistribute tensile and compressive forces. The author discusses the development of these tools and their application.

BACKGROUND The aim of the present work was to evaluate the stress magnitudes and directions along the midpalatal suture in the maxillary protraction therapy. METHODS The geometry of the maxilla and teeth were digitally reconstructed based on computer tomography images obtained from the skull of a girl in a mixed dentition stage with skeletal and dental class III malocclusion. An appliance com...
