PURPOSE: Cervicothoracic paravertebral neoplasms extending into the mediastinum pose a surgical challenge due the complex regional anatomy, their biological nature, rarity and surgeon's unfamiliarity with the region. We aim to define a surgical access framework addressing the aforementioned complexities whilst achieving oncological clearance. METHODS: We carried out a retrospective review of 28 consecutive patients operated in two tertiary referral centres between 1998 and 2015...

Prosthetic joint failure is mainly caused by infection, aseptic failure (AF), and mechanical problems. Infection detection has been improved with modified culture methods and molecular diagnostics. However, comparisons between modified and conventional microbiology methods are difficult, due to variations in specimen sampling. In this prospective, multidisciplinary study of hip or knee prosthetic failures, we assessed the contributions of different specimen types, extended culture incubations, and 16S rRNA sequencing for diagnosing prosthetic joint infections (PJI)...

BACKGROUND: In children, surveys on Staphylococcus aureus have focused on specific infections, situations or strains but no study has so far given an overview on S. aureus isolation without any selection. Here, we describe the overall bacteriological and clinical characteristics of S. aureus isolation in children, with a special focus on isolates harbouring tst, sea, and/or luk-PV genes, respectively, encoding the three clinically relevant toxins: toxic shock syndrome toxin-1, enterotoxin A and Panton-Valentine leukocidin...

In a preliminary investigation of FDG-PET/CT for assessment of therapy response of pyogenic spine infection, it was concluded that activity confined to the margins of a destroyed or degenerated joint with bone-on-bone contact represents nonseptic inflammation, regardless of the intensity of uptake. Only activity in bone, soft tissue, or within the epidural space represents active infection. The purpose of this investigation was to assess the performance of these pattern-based interpretation criteria in a series of problem cases of proven or suspected spine infection...

BACKGROUND: To obtain adequate fixation in treating Lisfranc soft tissue injuries, the joint is commonly stabilized using multiple transarticular screws; however iatrogenic injury is a concern. Alternatively, two parallel, longitudinally placed plates, can be used to stabilize the 1st and 2nd tarsometatarsal joints; however this may not provide adequate stability along the Lisfranc ligament. Several biomechanical studies have compared earlier methods of fixation using plates to the standard transarticular screw fixation method, highlighting the potential issue of transverse stability using plates...

BACKGROUND: The treatment of malignant tumours of the distal tibia is a challenging surgical problem due to the scarce soft tissue coverage and the instability of the ankle joint that often occurs after resection. However, there is no consensus on the ideal treatment for malignant tumours of the distal tibia. METHODS: We report a new reconstruction for five patients with high-grade osteosarcoma of distal tibia, using dual ipsilateral vascularized autogenous fibular graft in a trapezoid-shaped array and external fixator, with ankle arthrodesis and preserving subtalar joints...

PURPOSE: This study is aimed to investigate the effects of the choice of femoral and tibial components on several mechanical outputs that might be associated with total knee replacement surgery outcomes using a validated computational model: the Kansas knee simulator. METHODS: Two models from the same range of implants were taken into account: Model 1, the femoral component fitted the femoral epiphysis, with physiological positioning of the articulating surface using a 10-mm-thick tibial component, and in Model 2, the femoral component was 4 mm smaller than in Model 1, and a 14-mm-thick tibial component was used with a similar tibial resection and the tibio-femoral joint line was 4 mm more proximal to compensate the increased posterior bone resection and maintain proper soft-tissue tension in flexion...

BACKGROUND: Heterotopic ossification (HO) is abnormal formation of lamellar bone in soft tissue; the most frequent causes are total hip arthroplasty and trauma. Severe cases can lead to ankilosis with important impact on quality of life. Surgery is the elective treatment, but, especially in high-risk patients, it is important to prevent the re-formation of HO and, in these cases, radiotherapy (RT) can play an important role. MATERIALS AND METHODS: we retrospectively analyzed a mono-institutional casistic of 30 patients (31 sites) at high risk for HO development, treated with surgery and pre- or postoperative RT...

The purpose of this study was to determine current practice patterns in the treatment of low energy gunshot wounds involving bones and joints. One hundred seventy-three Orthopaedic Trauma Association (OTA) members completed a web-based survey. The survey included practices for antibiotic therapy and operative treatment for different types of low-energy gunshot injuries. Six different scenarios of soft tissue injury, intra-articular injury, and fractures were described. Several permutations of antibiotic therapy and operative or non-operative management options were given as choices on the survey...

Dan Li, Longfei You, Songqing Fan, Lihua Tan
RATIONALE: Xanthomatosis often accompanies familial hypercholesterolemia. This disease usually occurs in tendons, most commonly located in the Achilles tendon; occasionally it can also be seen in other systems. Although there are previous reports for bilateral hand extensor tendon involvement, to our knowledge there is no report in English literature regarding bilateral hands with small joint synovium presenting as rheumatoid arthritis. Therefore, the case that is presented in this report is unique...

BACKGROUND: Studies have shown that the prognosis of the treatment of methicillin-susceptible S. aureus (MSSA) with glycopeptides is inferior compared to treatment with β-lactam. However, there are only few studies comparing treatment with antistaphylococcal penicillin alone to glycopeptide treatment. The aim of this study was to compare the efficacy of nafcillin, an antistaphylococcal penicillin, with that of glycopeptides as a definitive therapy for MSSA bacteremia. METHODS: Patients with MSSA bacteremia recruited from a tertiary referral hospital were enrolled in this retrospective cohort study...

The chest wall is a vast and complex structure, hence the wide range of pathological conditions that may affect it. The aim of this publication is to discuss the usefulness of ultrasound for the diagnosis of benign lesions involving the thoracic wall. The most commonly encountered conditions include sternal and costal injuries and thoracic lymphadenopathy. Ultrasound is very efficient in identifying the etiology of pain experienced in the anterior chest wall following CPR interventions. Both available literature and the authors' own experience prompt us to propose ultrasound evaluation as the first step in the diagnostic workup of chest trauma, as it permits far superior visualization of the examined structures compared with conventional radiography...

PURPOSE OF REVIEW: Tedizolid is a second-generation oxazolidinone with activity against Gram-positive bacteria, including MRSA isolates resistant to linezolid. Pivotal clinical trials showed that tedizolid at 200 mg once-daily for 6 days is not inferior to linezolid 600 mg twice daily for 10 days in patients with SSTI. The comparison of adverse events is favorable to tedizolid under the circumstances of the clinical trials. This is a review of recent literature on tedizolid, its use in special populations and potential adverse effects...
