BACKGROUND Posterior fixation alone may not be adequate to achieve and maintain burst fracture reduction. Adding screws in the fractured body may improve construct stiffness. This in vitro study evaluates the biomechanical effect of inserting pedicle screws in the fractured body compared with conventional short- and long-segment posterior fixation. METHODS Stable and unstable L2 burst fractur...

abstract : horizontal root fractures in permanent teeth are uncommon injuries among dental traumas. the principle of treating horizontal root fractures of permanent teeth is repositioning and fixation of fractured segment. diagnosis of tooth fractures based on radiographic findings and the fracture healing process are affected by factors before and after injury. the present case reports the tre...

t-condylar fracture of the distal humerus is rare in the skeletally immature children and is very rare in young children, under 9 years of age. this fracture has been classified  as:  type a ( minimally displaced or undisplaced), type b (displaced  but  not comminuted ) and type c (displaced and comminuted). herein, we report a t-condylar fracture of the distal humerus in a 5-yr-old boy. this f...

conclusions evaluating the size of the patient’s pupils before, during and after the operation, careful history, consult, ct scan and mri would help to diagnosis. although no probable cause was found to explain the transient mydriasis in our patient. introduction unilateral mydriasis is a seriously significant finding in neurologic examinations indicating life-threatening conditions such as cer...

Proximal interphalangeal joint injuries are common and often can be treated nonsurgically. Some dorsal fracture-dislocations, however, require special attention or surgical management to optimize outcomes. Treatment options for dorsal proximal interphalangeal fracture-dislocations include splinting, percutaneous pinning, fracture fixation, external fixation devices, volar plate arthroplasty, an...

Abstract The prevalence of mandibular fracture is relatively lower in the pediatric population compared to adults. The treatment of these fractures is more challenging for oral and maxillofacial surgeons due to the concerns regarding mandible growth and the presence of developing tooth buds. According to the literature, conventional methods (e.g., soft diets or closed red...

BACKGROUND Ultrasound-aided fixation is a recently developed alternative method of treatment of zygomatico-maxillary (ZM) fracture, and it can resolve the problems of excessive torsion force and subsequent fractures of screws. We conducted this study to evaluate the clinical usefulness of ultrasound-aided fixation as compared with the conventional fixation method using a drill and an expander i...

The diaphyseal tibia fracture is best treated with intramedullary nail but in some cases where the nail is not applicable, plate fixation will be the next option of fixation. The extensile anterior approach is normally used for conventional compression plate fixation in tibia shaft fractures. The extensive surgical dissection may devitalizes the bony fragments and interfere with the fracture un...
