Implantation of resorbable gentamicin sponges in addition to irrigation and debridement in 34 patients with infection complicating total hip arthroplasty.
Abstract We evaluated a prosthesis-retaining treatment protocol for prosthetic joint infection in patients presenting at a mean of 116 days (range 10-1216 days) after primary arthroplasty. Our regime involved irrigation and debridement followed by implantation of biodegradable gentamicin loaded sponges which do not require removal after implantation. Of 34 patients with a deep infection after total hip arthroplasty, Twenty-five were treated successfully, with a mean follow-up of 35 months. There were no permanent complications. This success rate is comparable to earlier studies. Early initiation of treatment demons...

Long stem cemented revision arthroplasty for aseptic loosening in elderly patients produces good results, despite significant bone loss.
Abstract We assessed the results of long cemented stems in patients over 65 undergoing a first time revision hip arthroplasty for aseptic loosening. 103 patients were followed up for a minimum of five years after revision surgery; 45% had EndoKlinik C grade preoperative bone loss. At final follow-up 31 patients had died, all but one with the prosthesis in situ. There were 71 revisions alive, one had been revised for a peri-prosthetic fracture. Of the 45 that had radiographs at a minimum of five years, three stems were probably or definitely loose according to the Harris classification. There was 92% patient satisfa...

Suspension criteria for dual energy X ray absorptiometry
The use of dual-energy X-ray absorptiometry (DXA) units primarily for the assessment of fracture risk and in the diagnosis of osteoporosis is ubiquitous in Europe and ever-expanding in its implementation worldwide. DXA is known for its reported low radiation dose and precision in the determination of bone mineral density. However, the use of simple suspension criteria, as proposed in the new EC report RP-162, will identify units that are unfit for useful and safe diagnosis. Such suspension levels, however, are not a substitute for regular maintenance, quality control testing and optimisation of clinical outcomes.

Response to “Benefit of Helicopter Emergency Medical Services on trauma patient mortality in the Netherlands?”
We thank the four Dutch HEMS centres for their critical evaluation of our paper. The main goal of our study was to assess the quality of care provided by the chain of prehospital and hospital trauma care. Until now such data are unfortunately not available on a nationwide based registry. As provided in the discussion we do not consider our current results and conclusions as the end of a phase, but just the beginning of a better, more reliable matrix to monitor the quality of care.

Comminuted quadrilateral plate fracture fixation through the iliofemoral approach
Abstract: Comminuted quadrilateral plate fracture with medial displacement is a technically difficult fracture to treat. Minimal bone stock, proximity to the hip joint with limited surgical access, and difficulty in obtaining a stable fixation at this area, contribute to the surgical challenge of open reduction and internal fixation. Fixation of a medial buttress plate in an infrapectineal fashion is a well-described technique to address such fractures. However, this plate alone may be inadequate to buttress all the fragments in a grossly comminuted quadrilateral plate fracture. An additional spring plate is often placed u...

Periprosthetic fractures in the resurfaced hip—A case report and review of the literature
Abstract: Traumatic periprosthetic fractures adjacent a hip resurfacing prosthesis are rare. When proximal fractures are encountered the obvious surgical solution is to revise to a large head stemmed femoral component. A previously well functioning implant may however be retained as various non-operative and operative treatment options exist. This paper reports the case history of a traumatic periprosthetic fracture successfully treated with cannulated screw fixation and reviews the current literature.

Less invasive polyaxial locking plate fixation in periprosthetic and peri-implant fractures of the femur—A prospective study of 41 patients
Conclusion: Periprosthetic fracture fixation can be performed as part of a standardised less invasive strategy, but the MI technique should be the preferred treatment. The NCB® system allows for a stable plate fixation around an intramedullary implant. With the less invasive technique, long plates can be applied with low rates of soft-tissue complication and implant failure.

Intraoperative computed tomography with integrated navigation in percutaneous iliosacral screwing
Conclusions: An iCT with an integrated navigation system provided accuracy for percutaneous iliosacral screwing. In addition, the accumulated dose was minimized for surgeons. However, effective dose of radiation in iCT with an integrated navigation system group was higher than fluoroscopic-assisted iliosacral screwing in hands of the same group of surgeons. No neurologic complications occurred. The iCT with an integrated navigation system provided an alternative to percutaneous iliosacral screwing.

Reduction and fixation capabilities of different plate designs for pubic symphysis disruption: A biomechanical comparison
Conclusions: The experimental results suggest a biomechanical advantage in using prebended plates for symphysis fixation compared to non-bended plates. Best results with regard to compression and increased contact area can be achieved by anatomically contoured plates with combined DC and locking screw capabilities. These findings are of special interest in pelvic surgery for choosing the right implant in severe displacements, obese patients and symphysiodesis techniques.

Vascular risk reduction during anterior surgical approach sacroiliac joint plating
Conclusion: Familiarity of the vasculature of the internal pelvis is of utmost importance for the surgeon when considering operative fixation of the anterior SI joint. We were able to identify the relation of the nutrient artery to the anatomic landmarks of the internal pelvis and to define the “at risk area” for the nutrient artery. We believe increased understanding of the anatomy of the nutrient artery will aid in the avoidance of vascular complications during internal fixation of the anterior SI joint.

Grading of injury severity – What should be the prerequisites to separate multiply injured patients from those in critical condition and polytrauma?
The grading of injury severity has become a crucial issue in health care. In developed countries, multiple different scoring systems serve various purposes. Some of them were developed to grade patients on scene, some on admission and some during the hospital course. In addition, many scores are in use to monitor complications, such as ARDS, MODS or MOF.

Invited commentary
This report by Calligaro et al regarding stent angioplasty across the inguinal ligament, although a limited experience with a select group of patients, lends promise to a technique previously thought to be avoided at all costs. Crossing the inguinal ligament was thought to lead to stent kinking, fracture, and certain occlusion. There were also concerns about occlusion of the profunda femoris artery when stenting into the area of the femoral artery and the femoral bifurcation. These concerns regarding occlusion, enhanced hyperplasia, and the profunda femoris precluded most physicians from using this technique despite less t...

New Insights Into The Mechanics Of Muscle Fatigue
A study in The Journal of General Physiology examines the consequences of muscle activity with surprising results, indicating that the extracellular accumulation of potassium that occurs in working muscles is considerably higher than previously thought. Muscle excitation involves the influx of sodium ions and efflux of potassium ions. Although the fraction of ions that cross the muscle membrane with each contraction is minute, repeated activity can lead to substantial changes in the intracellular and extracellular concentrations of sodium and potassium ions...

Enhancing Damage Visibility on Metallic Bearing Surfaces: A Simple Technique for Photography and Viewing
Abstract: Damage to metallic bearing surfaces typically involves scratches, scrapes, metal transfer, and organic deposits. This damage can cause accelerated wear of the opposing surface and subsequent implant failure. Photography and viewing of metallic bearing surfaces, for documenting this damage, are hindered by optical reflectivity. This note demonstrates a simple, practical technique for metallic bearing surface photography and viewing that minimizes this reflectivity problem, that does not involve any modification of the bearing surface, and that allows for improved observation and documentation of overall damage.
