Amol Saxena, Andrew Yun
The purpose of the present study was to describe a minimally invasive percutaneous technique for plating Weber B distal fibular fractures and to evaluate its efficacy by measuring patient outcomes and hardware removal rates. The data from 17 patients undergoing percutaneous plating of a distal fibular (Weber B) fracture were prospectively studied. A 4- to 6-hole semitubular plate with 3 screws was used for percutaneously plating. The Roles and Maudsley score was used to assess the patients' activity level...

Superparamagnetic relaxometry (SPMR) is a highly sensitive technique for the in vivo detection of tumor cells and may improve early stage detection of cancers. SPMR employs superparamagnetic iron oxide nanoparticles (SPION). After a brief magnetizing pulse is used to align the SPION, SPMR measures the time decay of SPION using super-conducting quantum interference device (SQUID) sensors. Substantial research has been carried out in developing the SQUID hardware and in improving the properties of the SPION. However, little research has been done in the pre-processing of sensor signals and post-processing source modeling in SPMR...

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...

Suture button devices such as the TightRope (Arthrex, Naples, Florida) have been increasingly used for syndesmotic fixation of ankle fractures. Despite proposed advantages, prior studies have shown equivalent outcomes, with a theoretical decreased need for removal of hardware. Complications of suture button fixation of syndesmotic instability may be underreported and include lateral suture knot inflammation with or without granuloma formation, infection, aseptic osteolysis with widening of the tibial drill tunnels, heterotopic ossification, and osteomyelitis...

INTRODUCTION: Distal radius fracture are common injuries but no gold standard for their therapy exists. The aim of this study was to evaluate the quality of fracture care in distal radius fractures using an intramedullary implant (Targon DR interlocking nail). The nail had been developed to minimize the surgical exposure, increase fixation strength, to prevent tendon irritations and to allow for a fast return to activity. PATIENTS AND METHODS: Prospective study reports the result of 43 patients with an age over 70 years (range 70-91 years) treated by closed reduction and intramedullary fixation...

BACKGROUND: While trans-syndesmotic fixation with metal screws is considered the gold standard in treating syndesmotic injuries, controversy exists regarding the need and timing of postoperative screw removal. Formal recommendations have not been well established in the literature and clinical practice is highly variable in this regard. The purpose of this systematic review is to critically examine the most recent literature regarding syndesmotic screw removal in order to provide surgeons an evidence-based approach to management of these injuries...

Semi-permanent dual-lumen tunneled (or tunneled-cuffed) hemodialysis catheters (TDC) are increasingly utilized during renal replacement therapy, while awaiting permanent access maturation or renal recovery. Although there is a wealth of literature focused on placement, infection prevention, and maintenance of catheter patency, circumstances and indications for TDC removal are less well understood. Timely removal of these catheters is an important management decision, with the length of TDC duration representing the largest cumulative risk factor for catheter-associated blood stream infections...

BACKGROUND: Osteosynthesis plate removal is one of the most commonly performed procedures in orthopaedic surgery. Due to technological advances and the quality of increasing osteosynthesis material, more and more locked plates have been implanted over the last 20 years. The aim of this study was to determine whether the complication rate during plate removal differs between conventional and locked plates. MATERIAL AND METHODS: In this retrospective cohort study, 620 patients were included and divided into two groups based on the type of plate (locked and conventional)...

Patients with retained tibial implants may later undergo total knee arthroplasty (TKA) after tibial osteotomy or fracture. Previous knee surgery can increase the rate of complications of joint replacement. Surgical scars may not be in optimal position for hardware removal and arthroplasty. The need for multiple incisions or larger subcutaneous skin flaps in at-risk areas may increase the possibility of wound complications and infection. In this article, we report 3 cases in which a patient who had knee arthrosis and retained tibial implants underwent single-stage conversion to TKA...

BACKGROUND: In recent years, the number of total ankle arthroplasty procedures performed has increased dramatically. We sought to report the clinical results of the largest cohort of patients treated with a modern fixed-bearing total ankle arthroplasty by a single surgeon. METHODS: We retrospectively reviewed the charts of 78 consecutive patients (81 ankles) who underwent total ankle arthroplasty with a minimum clinical follow-up of 2 years. Sixty-three patients completed standardized questionnaires including the Foot and Ankle Disability Index (FADI), the Short Musculoskeletal Function Assessment (SMFA), the Short Form (SF)-36v2, and a visual analog scale (VAS) for pain...

Sample preparation is the bottleneck of many analytical methods, including ion chromatography (IC). Procedures based on the application of membranes are important, yet not well appreciated means for clean-up and analyte preconcentration of liquid samples. Filtration, ultrafiltration, the variety of dialysis techniques, i.e. passive dialysis, Donnan dialysis and electrodialysis, as well as gas-diffusion are being reviewed here with respect to their application in combination with IC. Instrumental aspects including hardware requirements, configuration of membrane separation units and membrane characteristics are presented...

Magnetic resonance imaging (MRI) is a non-destructive technique that is capable of localizing pathologies and assessing other anatomical features (e.g., tissue volume, microstructure, and white matter connectivity) in postmortem, ex vivo human brains. However, when brains are removed from the skull and cerebrospinal fluid (i.e., their normal in vivo magnetic environment), air bubbles and air-tissue interfaces typically cause magnetic susceptibility artifacts that severely degrade the quality of ex vivo MRI data...

The aim of the present study was to assess the technical feasibility of minimally invasive volar plate removal following distal radius fracture. 388 plates removed from 387 patients (357 female: mean age, 50 years) were assessed retrospectively. The incision used the primary minimally invasive approach and was closed after plate removal by intradermal continuous suture, without drainage or immobilization. Mean scar size was 22.2mm preoperatively, and the incision was 19.8mm at start and 21.4mm at end of procedure, these differences being non-significant...

Background Articular cartilage lesions of the talus remain a challenging clinical problem because of the lack of natural regeneration and limited treatment options. Microfracture is often the first-line therapy, however lesions larger than 1.5 cm(2) have been shown to not do as well with this treatment method. Methods The objective of this retrospective study was to evaluate the outcomes of iliac crest bone marrow aspirate concentrate/collagen scaffold (ICBMA) and particulated juvenile articular cartilage (PJAC) for larger articular cartilage lesions of the talus...

Ankle fractures are accompanied by a syndesmotic injury in about 10% of operatively treated ankle fractures. Usually, the total rupture of the syndesmotic ligaments with an external rotation force is associated with a Weber type B or C fracture or a Maisonneuve fracture. The clinical assessment should consist of a comprehensive history including mechanism of injury followed by a specific physical examination. Radiographs, and if in doubt magnetic resonance imaging, are needed to ascertain the syndesmotic injury...

INTRODUCTION: Tension-band wire fixation of patellar fractures is associated with significant hardware-related complications and infection. Braided polyester suture fixation is an alternative option. However, these suture fixations have higher failure rates due to the difficulty in achieving rigid suture knot fixation. The Arthrex syndesmotic TightRope, which is a double-button adjustable loop fixation device utilizing a 4-point locking system using FibreWire, may not only offer stiff rigid fixation using a knotless system, but may also obviate the need for implant removal due to hardware related problems...
