DTs are rare tumors, corresponding to only 0.03% of all neoplasia and less than 3% of all soft tissue tumors. Most of the tumors occur in the abdomen and presentation in the extremities is uncommon. Here, we present a review of the literature and the 27th case of DT of the foot.</p> Thiago Batista Faleiro1, Rogério Gouvêa1, Clarice de Abreu Silva2, Bruno Adelmo Ferreira Mendes Franco2, Thales Felipe Lucas Sena2, Gildásio Daltro2, Alexandre Vasconcelos de Meirelles1 Copyright (c) 2021 Fri, 01 Jan 2021 00:00:00 +0000 Relationship Between Peroneal Tendons and Anterior Talofibular Ligament <p>Background: Anterior talofibular ligament (ATFL) injuries are the most common in ankle torsional injuries. ATFL and peroneal tendons are both important stabilizers of lateral ankle joint. We aimed to evaluate peroneal tendons and ATFL.</p> <p>Methods: Fifteen nonpaired leg of fresh frozen cadavers were assessed in this study. After harvesting, ATFL diameters were measured at three points by calipers, these are fibular side, intermediate side and talar side. The mean of these three measurements were assessed and tissue a 15 lb load was applied to the peroneal tendons for 10 minutes, and the transverse diameters were measured by folding the thickest part of the tendon in a double-strand.</p> <p>Results: 5 single bundle, 8 double-bundle and 2 three bundles of ATFL were obtained after dissection. . There was no correlation between ATFL diameter, peroneus longus, peroneus brevis and total tendon diameters of peroneus longus and peroneus brevis in women (p&gt; 0.05). A strong correlation was found between ATFL diameter, peroneus longus (r: 0.95), peroneus brevis (r: 0.81) and total tendon diameters of peroneus longus and peroneus brevis (r: 0.92) in men.</p> <p>Conclusion: Relationship between the diameter of the ATFL and peroneal tendons diameters were evaluated and a correlation was observed in males, while no correlation was observed in females.</p> Ahmet Oztermeli, Nazım Karahan Copyright (c) 2021 Fri, 01 Jan 2021 00:00:00 +0000 CURRENT STATUS OF DIAGNOSIS AND TREATMENT OF FEMORAL NECK FRACTURES IN THE ELDERLY <p>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.</p> Shunhan Yao, Dinggui Lu Copyright (c) 2021 Thu, 28 Jan 2021 00:00:00 +0000 SINGLE STAGE KNEE ARTHROPLASTY REVISION SURGERY, OUR EXPERIENCE WITH ELEVEN CASES AND REVIEW OF THE LITERATURE <p>Knee replacement is a widely performed and very successful procedure for the management of knee arthritis. 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].</p> <p>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].</p> <p>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.</p> <p>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 month of the index procedure, acute haematogenous, presenting with acute symptoms in a previously well – functioning joint, and late chronic, where infection develops later than one month postoperatively [8].</p> <p>Management of PJI’s is mainly surgical, reserving conservative treatment for patients unable to undergo surgery [9]. Surgical options include debridement and retention of the prosthetic implants (DAIR), two – stage exchange revision, single – stage exchange revision, permanent resection arthroplasty, and finally amputation as the last measure [10]. DAIR is a viable option in early stages of acute infections, but established chronic infections necessitate more radical methods.</p> <p>Two – stage revision that was originally described by Install [11], secondly modified through the development of static spacers [12], and then articulating spacers [13], is considered the gold standard of TKA infection management [14]. A large volume of literature reports successful eradication of PJIs in more than 90% of patients using this approach [15,16,17]. Nevertheless, this procedure is costly, time-consuming, develops stiffness, arthrofibrosis, impairs mobility and increases inpatient stay. Single-stage revision arthroplasty for infection was first described in the 1980s [18, 19], has gained popularity for use in selected patients [20]. Infection control using this approach is achieved in 67% to 95% of patients [21, 22, 23, 24]. Furthermore, it is associated with less patient morbidity, improving functional outcome and reducing cost [25, 20].</p> <p>This paper seeks to systematically review the results of using single – stage revision arthroplasty for chronic infection of TKAs. Furthermore, we report our experience with eleven cases of chronic knee arthroplasty infection, which were treated with the aforementioned technique.</p> Andreas X.

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.</p> <p>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.</p> <p>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.</p> <p>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 of a femoral stem, returning the stem to its original position does not significantly compromise the integrity of the cement mantle or the pullout strength of the femoral implant. Small displacement of the femoral stem with prompt correction during cement curing does not cause evident cement mantle defects or a loss of femoral stem pullout strength.</p> Michael P.
