objectives: implant primary stability is one of the important factors in achieving implant success. the osteotome technique may improve primary stability in patients with poor bone quality. the aim of this study was to compare implant stability using two different techniques namely osteotome versus conventional drilling in the posterior maxilla. materials and methods: in this controlled randomi...

OBJECTIVE To evaluate the effect of real-time ultrasound guidance using a regular or Doppler ultrasound technique for placement of central venous catheters. DATA SOURCES We searched for published and unpublished research using MEDLINE, citation review of relevant primary and review articles, conference abstracts, personal files, and contact with expert informants. STUDY SELECTION From a poo...

BACKGROUND Conventional placement of a wireless esophageal pH monitoring device in the esophagus requires initial endoscopy to determine the distance to the gastroesophageal junction. Blind placement of the capsule by the Bravo delivery system is followed by repeat endoscopy to confirm placement. Alternatively, the capsule can be placed under direct vision during endoscopy. Currently there are ...

Introduction: In the United States, sigmoid volvulus is frequently seen in the elderly and neurologically impaired, driving a search for less invasive but effective treatments that may obviate the need for resection. This case study describes a novel technique for sigmoidopexy: a modified endoscopic approach for percutaneous endoscopic colostomy (PEC) tube placement in combination with laparosc...

tive technique for the percutaneous insertion of large-bore catheters into blood vessels that allowed for the application of angiocatheters for angiography. The Seldinger technique for central venous catheter (CVC) placement is ubiquitous in medical practice and the procedure is well known. Briefly, the procedure involves introducing a percutaneous needle into the vessel, passing a guidewire th...

BACKGROUND In 1991 Lindaman et al described a fluoroscopic technique to determine the incision site for percutaneous fixation of a slipped capital femoral epiphysis.1 Using similar principles, we describe a simple technique to improve the accuracy of crossed K-wire placement in displaced paediatric supracondylar fractures of the humerus. Although not original, our technique is very useful and w...

BACKGROUND Any landmark-based regional anaesthetic technique raises two important issues. The first is the accuracy of placement of the needle and thus the local anaesthetic in a 'blind' technique and the second is the potential for damage to adjacent structures. We designed a prospective, blinded study in an adult general surgical population to evaluate with ultrasound the placement of the nee...

Background—To simplify extensive primary repair of the thoracic aorta in acute type A aortic dissection, we developed the open triple-branched stent graft placement technique. The early results of this new technique are reported. Methods and Results—Between June 2008 and November 2009, 30 patients with acute Stanford type A aortic dissection underwent extensive primary repair of the thoracic ao...

OBJECTIVE Cervical pedicle screw (CPS) placement is very challenging due to high risk of neurovascular complications. We devised a new technique (medial funnel technique) to improve the accuracy and feasibility of CPS placement. METHODS We reviewed 28 consecutive patients undergoing CPS instrumentation using the medial funnel technique. Their mean age was 51.4 years (range, 30-81 years). Preo...

OBJECTIVE The aim of this study was to present a new technique of secondary vocal prosthesis placement on an outpatient basis without general anesthesia by means of digestive endoscopy. METHODS It is a prospective study, 35 laryngectomized patients were sedated with midazolam and underwent digestive endoscopy and tracheoesophageal punch with vocal prosthesis insertion. RESULTS A success rat...
