Veerappa N Radhakrishna, Vrisha Madhuri
We evaluated the novel application of supracutaneous locked plates in pediatric open tibia fractures. Pediatric open tibia fractures stabilized with a locked supracutaneous plate from January 2011 to December 2014 were reviewed. Twenty-eight children, mean age 8.9 years, with 29 open tibia fractures were included. Nine of these children who had metaphyseal or metadiaphyseal fractures did not require joint spanning. The mean follow-up duration was 13.5 months. The mean time to uneventful union was 11.46 weeks, with no unacceptable malunion...

Ankle dislocations are orthopedic emergencies that require immediate treatment to avoid neurovascular impairment. They are usually accompanied by one or more comminuted fractures of the ankle mortis. In rare circumstances, such as high-energy trauma, the ankle dislocations may not be accompanied by concomitant malleolar fractures and, thus, are named "pure ankle dislocations". We presented a very rare and interesting case of an open medial dislocation of the ankle without associated fracture in an 18-year-old man with no known predisposing risk factors...

INTRODUCTION: Atlantoaxial rotational fixation (AARF) is a rare entity in adults, with only a few cases reported in the English literature and often associated with a traumatic mechanism. It is an underdiagnosed condition that must be taken into account in the initial assessment of all craniocervical trauma. Both diagnostic and therapeutic delay may be a potential cause of severe neurological damage or even death of the patient. The therapeutic management is controversial given the difficulty of achieving optimum stability and permanent reduction...

Deformation of skeletal muscle in the proximity of bony structures may lead to deep tissue injury category of pressure ulcers. Changes in mechanical properties have been proposed as a risk factor in the development of deep tissue injury and may be useful as a diagnostic tool for early detection. MRE allows for the estimation of mechanical properties of soft tissue through analysis of shear wave data. The shear waves originate from vibrations induced by an external actuator placed on the tissue surface. In this study a combined Magnetic Resonance (MR) compatible indentation and MR Elastography (MRE) setup is presented to study mechanical properties associated with deep tissue injury in rats...

The method of osteogenesis by distraction is a known technique in orthopaedics for the management of bone defects secondary to trauma, infections or tumours. New strategies have been developed for decreasing the external fixator time. The use of the minimally invasive plate osteosynthesis technique is a secure approach through a percutaneous fixation technique in the anterior aspect of the femur that permits minimal dissection of the soft tissues while preventing cross-contamination with the pin tracts of the external fixators...

External periodic stimuli entrain brain oscillations and affect perception and attention. It has been shown that background music can change oculomotor behavior and facilitate detection of visual objects occurring on the musical beat. However, whether musical beats in different tempi modulate information sampling differently during natural viewing remains to be explored. Here we addressed this question by investigating how listening to naturalistic drum grooves in two different tempi affects eye movements of participants viewing natural scenes on a computer screen...

REVIEW
P Bonnevialle
Early infection after open reduction and internal fixation (ORIF) of a limb bone is defined as bacteriologically documented, deep and/or superficial surgical-site infection (SSI) diagnosed within 6months after the surgical procedure. This interval is arbitrarily considered sufficient to obtain fracture healing. The treatment of early infection after ORIF should be decided by a multidisciplinary team. The principles are the same as for revision arthroplasty. Superficial SSIs should be differentiated from deep SSIs, based on the results of bacteriological specimens collected using flawless technique...

BACKGROUND: Loosening of screws is a common problem in orthopedic and maxillofacial surgery. Modifying the implant surface to improve the mechanical strength of screws has been tried and reported. We developed screws coated with fibroblast growth factor-2 (FGF-2)-apatite composite layers. We then showed, in a percutaneous external fixation model, that this composite layer had the ability to hold and release FGF-2 slowly, thereby reducing the risk of pin tract infection of the percutaneous external fixation...

BACKGROUND: As the tibial bone defect increases in size, the problems in treatment also increase. The treatment may be problematic but different treatment approaches can be used. Among these approaches, distraction osteogenesis is a method an orthopedic surgeon with limited conditions can use although it has a longer treatment period. In our case series, we evaluated current treatment approaches. METHOD: Retrospective study based on patient records and radiographs...

Charcot's neuroarthropathy can have devastating consequences if left untreated or misdiagnosed. With progression of the disease from the acute to the chronic phase, substantial deformity and instability may result, leading to ulceration and a nonfunctional limb. The purpose of this case report is to present a staged reconstruction for active Charcot's neuroarthropathy involving the subtalar joint with complete dislocation that resulted in limb salvage and maintenance of limb function at 1-year follow-up. Although for many patients the mainstay of treatment for early Charcot's neuroarthropathy is conservative care with off-loading, early surgical correction that includes external fixation followed by definitive arthrodesis for select patients may be warranted...

Ankle distraction is an alternative to ankle arthrodesis or total ankle arthroplasty in younger patients with arthritis. Ankle distraction involves the use of external fixation to mechanically unload the ankle joint, which allows for stable, congruent range of motion in the setting of decreased mechanical loading, potentially promoting cartilage repair. Adjunct surgical procedures are frequently done to address lower-extremity malalignment, ankle equinus contractures, and impinging tibiotalar osteophytes. Patients can bear full weight during the treatment course...
