BACKGROUND: Chronic coronoid deficiency can occur subsequent to coronoid fracture malunion/nonunion or to coronoid hypoplasia or dysplasia resulting from injury during development. Several surgical options have been described to treat this difficult condition, but results are equivocal. We hypothesized that a modified coronoid reconstruction using a radial head osteochondral graft could restore elbow stability and congruity and that a technique involving rigid internal fixation would promote graft union...

Posterior dislocations of the hip are known to be associated with fractures of the femoral head, neck, shaft, or posterior acetabular wall. However, its association with ipsilateral intertrochanteric fracture has only been anecdotally described in the English literature. We report two such cases managed by open reduction (OR) of the hip and internal fixation (IF) of the intertrochanteric fracture. The first case was a 26-year-old male who was managed by OR of the hip with IF of the intertrochanteric fracture with a dynamic hip screw and had a good functional result at 1-year followup...

The treatment of impacted distal radius fractures is complex. Internal fixation by a dorsal approach with arthrotomy should be considered, particularly when the fractures are dorsally comminuted. This was a retrospective, observational study of 26 patients operated between 2008 and 2012 who were reviewed in September 2013. In the surgical procedure, a single dorsal incision was made over the distal radius and arthrotomy performed; the fracture site was stabilized with two 2.4mm locking plates. The average follow-up was 39months...

BACKGROUND: Sternal fractures are relatively rare, and caused mainly by blunt anterior chest wall trauma. In most cases, sternal fractures are treated conservatively. However, if the patient exhibits problematic symptoms such as intractable chest wall pain or bony crepitus due to sternal instability, surgical correction is indicated. But no consensus exists regarding the most appropriate surgical method. We analyzed the results of surgical fixation in cases of sternal fracture in order to identify which surgical method led to the best outcomes...

AIM: Fascioliasis is one of the most zoonotic diseases with global extension. As the epidemiological distribution of Fasciola may lead to various genetic patterns of the parasite, the aim of this study is to identify Fasciola hepatica based on spermatogenesis, and phylogenetic analysis using mitochondrial (nicotiamide adenine dinucleotide dehydrogenase subunit I [ND1] and cytochrome oxidase subunit I) gene marker. MATERIALS AND METHODS: In this study, 90 F. hepatica collected from 30 cattle at slaughterhouse located in three different geographical locations in the North-East of Iran were evaluated based on spermatogenetic ability and internal transcribed spacer 1 gene restriction fragment length polymorphism pattern...

BACKGROUND: Axillary nerve injuries after shoulder surgery are rare. In most studies, the frequency of injury is usually determined using clinical examinations, but results from intraoperative neuromonitoring studies have revealed higher than expected rates. Few studies have investigated this topic. Our aim was to determine the frequency of axillary nerve lesions after open reduction and internal fixation of proximal humeral fractures by using electrophysiological assessments and to provide a review of the relevant literature...

Arginine-rich cell-penetrating peptides (CPPs) including Tat, Penetratin and oligoarginine peptides are a series of short peptides that can be efficiently internalized into cells and have been widely used as carriers for intracellular delivery of bioactive molecules. In the early phase of the study, CPPs, as well as their conjugates, were thought to rapidly enter cells by direct penetration through membranes, which was later found to be an experimental artifact that was concluded from observations in fixed cells...

PURPOSE: Intramedullary and extramedullary fixation methods are widely used to treat unstable femoral intertrochanteric fractures, but the optimal surgical method remains controversial. The aim of this study was to estimate the outcomes of intramedullary fixation versus extramedullary fixation in treating unstable femoral intertrochanteric fractures. METHODS: Electronic literature databases were used for searching including MEDLINE (Ovid interface), EMBASE (Ovid interface) and the Cochrane Central Register of Controlled Trials (CENTRAL) (Wiley Online Library) (up to March 30, 2016)...

BACKGROUND: Treatment of supraintercondylar (AO/OTA 33-C) and supracondylar (AO/OTA 33-A) femur fractures is generally challenging. Standard treatments include open reduction and internal fixation. However, optimal implants are now being well-defined. This study focus on the comparison between clinical and functional outcomes of fractures treated with condylar buttress plates (CBPs). METHODS: We treated 87 patients with supraintercondylar or supracondylar femur fracture from 2004 to 2008, including 30 supraintercondylar and 24 supracondylar fractures treated with CBPs...

Pelvic ring fractures are defined as life-threatening injuries that can be treated surgically with external or internal fixation. The authors report on an 81-year-old woman with an unstable pelvic fracture accompanying multiple traumas that was successfully treated with a less invasive procedure. The patient was injured in a traffic accident and sustained a total of 20 fractures, including pelvic ring, bilateral rib, and lumbar transverse processes fractures, and multiple fractures of both upper and lower extremities...

Rapid cooling of aqueous solutions is a useful approach for two important biological applications: (I) cryopreservation of cells and tissues for long-term storage, and (II) cryofixation for ultrastructural investigations by electron and cryo-electron microscopy. Usually, both approaches are very different in methodology. Here we show that a novel, fast and easy to use cryofixation technique called self-pressurized rapid freezing (SPRF) is-after some adaptations-also a useful and versatile technique for cryopreservation...

Supracondylar humerus fractures and lateral condyle fractures are the two most common pediatric elbow fractures that require surgical intervention. Although most surgeons are familiar with supracondylar humerus fractures and lateral condyle fractures, these injuries present challenges that may lead to common errors in evaluation and management and, thus, compromise outcomes. It is well agreed upon that nondisplaced supracondylar fractures (Gartland type I) are best managed nonsurgically with cast immobilization...

The pediatric lower extremity has well known growth patterns. When deformities or growth disturbances occur, there are several methods to measure and predict the resulting discrepancy, including the Green-Anderson, Moseley, and Multiplier methods. Many techniques exist to correct leg length discrepancy and deformity such and temporary epiphysiodesis, permanent epiphysiodesis, external fixators, and internal lengthening devices. All of these methods have numerous complications and limitations; however, with careful planning and patient selection, length and alignment can be improved with high patient satisfaction...

Displaced radial head fractures are treated with open reduction and internal fixation using implants. Failure of fixation may occur in the presence of comminution and in multifragmentary fractures; open surgical approaches are necessary for removal of the implants and radial head resection. Arthroscopic radial head resection has been described as a minimally invasive and effective treatment for failed radial head fracture fixation; however, periarticular adhesions and prominent implants add to the complexity and technical difficulty of the procedure...
