The mechanical behavior of the transosseous elements is a defining factor in the overall stiffness, stability, and reliability of an external fixation system. Mechanics involving the application of thin Kirschner wires in Ilizarov apparatus is yet to be fully explained. To address this problem, load-deflection behavior of the pretensioned thin wires laterally loaded by the bone is necessary to ...

PURPOSE To compare a Teflon prosthesis to a piston-type wire/Teflon prosthesis assessing auditory results post-Stapedectomy. MATERIAL AND METHODS We conducted a randomized controlled blinded clinical study from June 2003 to August 2004 at the Otorhinolaryngology, and Head and Neck Surgical Wards at the highly specialized medical unit of "La Raza" General Hospital National Medical Cen ter in M...

The patella is the largest sesamoid bone in the body. As the patella bone is responsible for the strong extensor mechanism of the knee joint, its reconstruction and anatomical restoration after fracture is always desirable over excision. Extra articular fracture of lower pole of patella accounts for less than 10 percent of all patellar fractures. The treatment of these fractures is complicated,...

OBJECTIVES Various methods for sternal approximation have been described previously. Some patients undergoing these procedures are at risk for sternal dehiscence and mediastinitis. We used a different method, with a suture anchor system, for median sternotomy closure as an alternate technique in patients with a high risk of postoperative sternal dehiscence and sternal nonunion. MATERIAL AND M...

BACKGROUND AND OBJECTIVE: Premature loss of mandibular first molar is a common problem in adults. Mesial tipping of second molar may occur in this situation. Various orthodontic mechanics have been proposed for molar uprighting. The aim of this study was to compare four methods of molar uprighting using Finite Element Analysis(FEM). METHODS: In first model of this finite element study, a 0.019...

BACKGROUND Variable methods have been introduced for reduction of the zygomatic fractures. The Dingman elevator is used widely to reduce these fractures but is inappropriate in certain types of fractures which require atypical traction vectors. We introduce and examine an alternate method of reducing zygomatic fractures using wire and hook traction. METHODS A retrospective study was performed...
