BACKGROUND: Radical release for severe stiff elbows may lead to instability. Hinged external fixation is used to treat unstable elbows. We hypothesized that extensive open release combined with a distal radius-positioned hinged external fixator would have good performance and low complications rate in treating severe elbow stiffness. Thus, the efficacy and security of this technique were assessed in this study. METHODS: We retrospectively reviewed 38 post-traumatic elbows with severe stiffness that underwent arthrolysis between February 2011 and February 2014...

BACKGROUND: Percutaneous pinning has been accepted as the "gold standard" for displaced supracondylar humeral fracture (SHF) in children. However, to secure an anatomic reduction and to reduce the rotated fragment, open reduction is often necessary when there is inadequate stabilization or a satisfactory reduction has failed to be achieved. The study aimed to compare the efficacy of the open reduction and bioabsorbable poly-d,l-lactic acid (PDLLA) pin fixation method with the closed reduction and lateral external fixation method in irreducible delayed Gartland type III SHF in children...

BACKGROUND: Locking compress plate, as external fixator, is an attractive technique for distal tibial fracture treatment. But it still remains unclear whether the external LCP has sufficient stiffness. Thus, the present study aims to make a comprehensive evaluation of the stiffness of external locking compress plate when it is used as an external fixator in distal tibial fractures treatment. METHODS: Composite tibia was used to simulate distal tibia fracture (Orthopedic Trauma Association type 43 A3 fracture)...

A new technique for manufacturing a patient-specific dosimetric phantom using three-dimensional printing (PSDP_3DP) was developed, and its geometrical and dosimetric accuracy was analyzed. External body contours and structures of the spine and metallic fixation screws (MFS) were delineated from CT images of a patient with MFS who underwent stereotactic body radiation therapy for spine metastasis. Contours were converted into a STereoLithography file format using in-house program. A hollow, four-section PSDP was designed and manufactured using three types of 3DP to allow filling with a muscle-equivalent liquid and insertion of dosimeters...

BACKGROUND: Stress fractures are the result of cyclic loading of the bone, which gradually becomes damaged. Most often they are treated by rest or plaster cast and, in rare cases, by internal fixation. There is little published data on initial reposition followed by stabilization with the Ilizarov apparatus in such fractures. MATERIAL AND METHODS: Six patients were treated with an external fixator according to the Ilizarov method for a stress fracture of the tibia between 2007 and 2015...

Heterotopic ossification (HO) is a common complication of the surgical treatment of acetabular fractures. HO is the formation of trabecular bone in soft tissues where bone does not usually occur. Over the last decade, many risk factors have been identified for HO after surgical fixation of acetabular fractures; however, prophylaxis and treatment of this condition are controversial. Potential preventive measures range from NSAIDs to external beam irradiation, but recent studies have questioned the utility of these measures...

In Ilizarov circular (ring) external fixators, fine Kirschner wires are used to fix the bone to the fixator. Clamping of the wires to the rings with different bolt torques has been studied. However, the relation between the bolt torque and the fixation load applied to the wire was not investigated. In this work, finite element method is used to address this problem. Here, a fully three-dimensional model of the wire fixation assembly was built, with geometric details like threads on the bolt to produce a realistic simulation of the clamping of the wire...

BACKGROUND: With an aging but still active population, open ankle fractures are increasingly presenting as low energy fragility injuries, sharing many characteristics with that of hip fractures. Yet, there is little in the literature on the management and outcome of these fractures. The primary aim of this study was to describe the outcome following open, ankle fragility fracture. Our secondary aim was to identify potential factors that improved outcome. METHODS: All consecutive, low energy open ankle fractures treated at a Level I Trauma Centre over a five-year period were included...

Three dimensional (3D) printing involves a number of additive manufacturing techniques that are used to build structures from the ground up. This technology has been adapted to a wide range of surgical applications at an impressive rate. It has been used to print patient-specific anatomic models, implants, prosthetics, external fixators, splints, surgical instrumentation, and surgical cutting guides. The profound utility of this technology in surgery explains the exponential growth. It is important to learn how 3D printing has been used in surgery and how to potentially apply this technology...

PURPOSE: Both external fixation(ExFx) and open reduction and internal fixation(ORIF) were used to treat complex tibial plateau fractures, but it was not sure which one was better. So we did this meta-analysis to evaluate the outcomes of ExFx and ORIF in managing complex tibial plateau fractures. METHODS: Articles published before August 5, 2016 were selected from PubMed, Cochrane library, and some other electronic database. Relevant journals were also searched manually with no language limited...

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...
