To evaluate the therapeutic effect of Pulsed Electromagnetic Field (PEMF) in the treatment of meniscal tears in the avascular region. Seventy-two twelve-week-old male Sprague-Dawley rats with full-thickness longitudinal medial meniscal tears in the avascular region were divided into 3 groups: control group (G. con. ), treated with classic signal PEMF (G. classic. ), and high slew rate signal PEMF(G. HSR. ). The HSR signal has the same pulse and burst frequencies as the classic signal, but with a higher slew rate. Macroscopic observation and histological analysis of the meniscus and articular cartilage were performed to evaluate the meniscal healing and progressions of osteoarthritis. The synovium was harvested for histological and immunofluorescent analysis to assess the intra-articular inflammation. The meniscal healing, articular cartilage degeneration, and synovitis were quantitatively evaluated according to their respective scoring system. Dramatic
The rotator cuff tendinopathy is one of the most common shoulder problems leading to full-thickness rotator cuff tendon tear and, eventually, to degenerative arthritis. Recent research on rotator cuff tendon degeneration has focused on its relationship to cell death. The types of cell death known to be associated with rotator cuff tendon degeneration are apoptosis, necrosis, and autophagic cell death. The increased incidence of cell death in degenerative tendon tissue may affect the rates of collagen synthesis and repair, possibly weakening tendon tissue and increasing the risk of tendon rupture. The biomolecular mechanisms of the

Glenoid and humeral head bone defects have long been recognized as major determinants in recurrent shoulder instability as well as main predictors of outcomes after surgical stabilization. However, a universally accepted method to quantify them is not available yet. The purpose of the present study is to describe a new CT method to quantify bipolar bone defects volume on a virtually generated 3D model and to evaluate its reproducibility. A cross-sectional observational study has been conducted. Forty CT scans of both shoulders were randomly selected from a series of exams previously acquired on patients affected by anterior shoulder instability. Inclusion criterion was unilateral anterior shoulder instability with at least one episode of dislocation. Exclusion criteria were: bilateral shoulder instability; posterior or multidirectional instability, previous fractures and/or surgery to both shoulders; congenital or acquired inflammatory, neurological, or
Adverse events (AEs) are still a major problem in spinal surgery, despite advances in surgical techniques, innovative technologies available and the introduction of checklist and predictive score systems aimed at reducing surgical complications. We previously analysed the results of the introduction of the WHO Safety Surgical Checklist (SSC) in our Institution, comparing the incidence of complications between two periods: from January to December 2010 (without checklist) and from January 2011 and December 2012 (with checklist), in order to assess the checklist effectiveness. The sample size was 917 patients with an average of 30 months of follow-up. Complications were observed in 107 patients (11.6%) among 917 spinal surgery procedures performed, with 159 (17.3%) complications in total. The overall incidence of complications for trauma, infectious pathology, oncology, and

Introduction. To face the problem of surgical complications, which is generally relevant in surgical fields, an intraoperative checklist (Safety Surgical Checklist, SSC) was elaborated and released by the World Health Organization in 2008, and its use has been described in 2009. In our Institution, the WHO SSC was introduced in 2011. In spinal surgery, many preventive measures were investigated to reduce complications, but there is no report on the effectiveness of the WHO checklist in reducing complications. Aim. The aim of this study was to compare the incidence of complications between the two periods, from January to December 2010 (without checklist) and from January 2011 to December 2012 (with checklist), in order to assess the checklist effectiveness. Materials and Methods. A retrospective and single center study was carried out on patients who underwent spinal surgery during the three-year period from January 2010 to December 2012. Patients were classified according to the spine pathology and the different presentation of the complication. We registered the complications arising in patients treated from 2010 to 2012 during a 3 years follow up period for each patient, assessing the possible differences before and after the checklist's introduction. Results. The sample size was 917 patients, the mean age was 52.88 years. The majority of procedures were performed for oncological diseases (54.4%) and

Introduction and Objective. Intervertebral disc (IVD) degeneration is one of the major contributors to low back pain, the leading cause of disability worldwide. This multifactorial pathological process involves the degradation of the extracellular matrix, inflammation, and cell loss due to apoptosis and senescence. While the deterioration of the extracellular matrix and cell loss lead to structural collapse of the IVD, increased levels of inflammation result in innervation and the development of pain. Amongst the known regulators of inflammation, toll-like receptors (TLRs) and more specifically TLR-2 have been shown to be specifically relevant in IVD degeneration. As strong post-transcriptional regulators, microRNAs (miRNAs) and their dysregulation has been connected to multiple pathologies, including

Abstract. Objectives. Identifying risk factors for inferior outcomes after anterior cruciate ligament reconstruction (ACLR) is important for prognosis and patient information. This study aimed to ascertain if BMI, pre-operative scores, demographic data and concomitant injuries in patients undergoing ACLR affected patient-reported functional outcomes. Methods. A prospective review collected data from a single surgeon series of 278 patients who underwent arthroscopic ACLR. BMI, age, gender, graft choice, pre-op Lysholm score, meniscal and chondral injuries were recorded. The Lysholm score, hop test and KT1000 were used to measure post-op functional outcome at one year. Multiple regression analysis was used to determine factors that predicted Lysholm scores at one year. Results. The mean age was 29 years, with 58 female and 220 male patients. The mean pre-op Lysholm score was 53.8. One hunded and seventy-nine patients had meniscal injuries, of which 81 were medial, 60 lateral, and 38 bilateral. Eighteen patients also had chondral injury and 106 patients had no other associated injury. Age, gender, graft type and presence of meniscal or chondral injuries did not affect one-year post-operative Lysholm scores. A BMI greater than 30, physio compliance and preoperative Lysholm scores helped predict one-year post-operative Lysholm scores (p=0.02). Pearson's correlation found a direct link between BMI and post-operative Lysholm (p=0.03). Conclusions. BMI, physio compliance and pre-operative Lysholm scores are the most significant determinants of short-term functional outcome after ACLR. However, the effects of associated injuries may be apparent in the long-term as
The surgical treatment of spinal deformities and degenerative or oncological vertebral diseases is becoming more common. However, this kind of surgery is complex and associated to a high rate of early and late complications. We retrospectively collected all the major complications observed in the perioperative and post-operative period for surgeries performed at our Division of Spine Surgery in the 2010–2012 period,. 285 surgeries were registered in 2010, 324 in 2011 and 308 in 2012. All the complications observed during the procedure and the follow-up period were recorded and classified according to the type (mechanical complications, neurological complications, infection, hematoma, cerebrospinal fluid fistula, systemic complications, death related to the surgery). In 2010, on 285 surgeries 47 patients (16.5 %) had 69 complications (24.2%): 25.7% for the treatment of oncological diseases, 23% for the treatment of
