Research Article of American Journal of Orthopedic Research and Reviews Motion and its Effects on the Cement Mantle - A Biomechanical Analysis of Femoral Stem Displacement during Implant Cementation Michael P. Ast, MD1; Adam Gitlin, MD2; Nadeen O. Chahine, PhD3; Daniel Grande, PhD4; Peter Lementowski, MD5 1Hospital of Special Surgery, New York, NY; 2University of Florida College of Medicine, Jacksonville, FL; 3Department of Biomechanics, Columbia Uni-versity, New York, NY; 4Feinstein Institute for Medical Research, Manhasset, NY; 5Westchester Medical Center, Valhalla, NY Background: It is a common notion that motion of a femoral component during cementation should be avoided as it may weaken the cement mantle. We created an in vitro model of cemented femoral components and subjected them to varying  rotational motion during the cement curing process, to measure the effect on the pullout strength of the stem. Methods:  21 sawbones femurs were separated into four groups.  The first group served as control and was cemented in a standard fashion. The remainder of the stems were divided into groups and subjected to angular rotational displacement within the cement mantle during curing .  Anteroposterior and lateral radiographs were obtained of each model to evaluate for cement defects. Pullout strength testing was performed. Results: Despite rotational displacement, no cement defects were noted on imaging.  The control stems showed an average pullout strength of 3735.79N. The experimental groups showed a trend for lower failure loads but it was not statistically significant (P=0.063). Of the 21 stems tested, three encountered cement mantle failure and associated stem pullout and the remainder failed by peripros-thetic fracture. Conclusion: Despite conventional thinking that rotational displacement during the cementing process leading to disruption of the cement mantle integrity, this was not borne out in our study.  This should give surgeons confidence that in the set-ting of unintended rotational displacement ...

Review Article of American Journal of Orthopedic Research and Reviews Single Stage Knee Arthroplasty Revision Surgery, Our Experience with Eleven Cases and Review of the Literature Andreas X.

Nevertheless, it is postulated that a total of 2-5% of primary and revision total knee arthroplasties (TKAs) is infected every year [1,2]. Despite the low incidence, the absolute numbers of prosthetic joint infections (PJIs) are growing, owing to an increased number of replacement surgeries, and are associated with significant morbidity and socioeconomic burden [3,4]. Although several definitions of PJI exist, Musculoskeletal Infection’s Society (MSIS) definition is based on strict criteria and is one of the most used [5]. Patients with certain risk factors have an increased risk to develop PJI [6,7]. Risk factors include presence of systemic or local active infection in an arthritic knee; previous operative procedures in the same knee, diabetes mellitus, malnutrition, smoking, alcohol consumption, co-morbidities, and immunosuppression; end-stage renal disease on hemodialysis, liver disease, intravenous drug abuse, and low safety operative room environment. PJIs are classified according to the depth of infection, to superficial and deep infections. Superficial infections are limited to the incision and superficial tissues, while deep infections, that involve deep layers, may occur up to one year postoperatively, and influence surgical management strategy. Timing of infection is also an important factor in guiding treatment. PJIs are classified to acute postoperative, within a ...


Review Article of American Journal of Orthopedic Research and Reviews CURRENT STATUS OF DIAGNOSIS AND TREATMENT OF FEMORAL NECK FRACTURES IN THE ELDERLY Shunhan Yao1, Dinggui Lu1,* 1Affiliated Hospital of Youjiang Medical University for Nationalities; No.18, Zhongshan 2nd Road, Baise, Guangxi, 533000, China Femoral neck fractures are common fractures in the elderly, especially in elderly women. There are many mature treatment methods for femoral neck fractures. However, which option is better is still controversial. In order to allow clinicians to better develop treatment plans for elderly patients with femoral neck fractures, this article summarizes the diagnosis and treatment status of elderly femoral neck fractures from the aspects of epidemiology, etiology and diagnosis, treatment methods and progress of elderly femoral neck fractures. Keywords: Elderly patients with femoral neck fracture, conservative treatment, surgical treatment, accelerated recovery ...
