New onset postoperative atrial fibrillation (AF) is the most common perioperative arrhythmia in the elderly. The incidence after total joint arthroplasty is much lower than other non-cardiac surgeries. Since postoperative atrial fibrillation can cause increased length of hospital stay, mortality, and healthcare costs, it is critical to focus on prevention and prompt management. New onset atrial fibrillation is treated with rhythm control for patients who demonstrate hemodynamic instability or refractory to rate control measures...

BACKGROUND: Access to affordable and timely surgery is not equitable around the world. Five billion people lack access, and while non-governmental organizations (NGOs) help to meet this need, long-term surgical outcomes, social impact or patient experience is rarely reported. METHOD: In 2016, Mercy Ships, a surgical NGO, undertook an evaluation of patients who had received surgery seven years earlier with Mercy Ships in 2009 in Benin. Using purposive sampling, patients who had received maxillofacial, plastics or orthopedic surgery were invited to attend a surgical evaluation day...

Patients with Turner syndrome (TS) frequently show short stature and skeletal deformities, such as kyphosis and scoliosis. However, to the best of our knowledge, limb length discrepancy (LLD) has not yet been reported in patients with TS. The case of a 12-yr-old girl with 45,X/47,XXX mosaic TS showing LLD is herein presented. She was on GH therapy for short stature and was noted to have scoliosis in the standing position at a regular examination; however, the scoliosis became less evident in the supine position, which is indicative of LLD...

BACKGROUND: Use of large databases for orthopedic research has become extremely popular in recent years. Each database varies in the methods used to capture data and the population it represents. The purpose of this study was to evaluate how these databases differed in reported demographics, comorbidities, and postoperative complications for primary total hip arthroplasty (THA) patients. METHODS: Primary THA patients were identified within National Surgical Quality Improvement Programs (NSQIP), Nationwide Inpatient Sample (NIS), Medicare Standard Analytic Files (MED), and Humana administrative claims database (HAC)...

STUDY DESIGN: Cross-sectional database study. OBJECTIVE: To train and validate machine learning models to identify risk factors for complications following posterior lumbar spine fusion. SUMMARY OF BACKGROUND DATA: Machine learning models such as artificial neural networks (ANNs) are valuable tools for analyzing and interpreting large and complex datasets. ANNs have yet to be used for risk factor analysis in orthopedic surgery. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for patients who underwent posterior lumbar spine fusion...

BACKGROUND: Healthcare policy is often determined by well-designed studies most often published in high-impact medical journals. However, concern about the presence of publication bias against lower-extremity arthroplasty-related studies has called into question some of the validity of certain reports. There are only a few studies investigating the presence of the bias in high-impact medical journals against lower-extremity arthroplasty intervention, particularly in the Journal of American Medical Association (JAMA), New England Journal of Medicine (NEJM), and the Lancet...

PURPOSE: Indications for removing orthopedic hardware on an elective basis varies widely. Although viewed as a relatively benign procedure, there is a lack of data regarding overall complication rates after fracture fixation. The purpose of this study is to determine the overall short-term complication rate for elective removal of orthopedic hardware after fracture fixation and to identify associated risk factors. MATERIALS AND METHODS: Adult patients indicated for elective hardware removal after fracture fixation between July 2012 and July 2016 were screened for inclusion...

Surgical treatment of unstable pelvic fractures Type C, has a vertical instability that is not controlled by traction and supine; therefore, orthopedic and functional treatments undertaken by default are sources of complications. The closed reduction with percutaneous sacroiliac fixation solves the problem of vertical instability; but at the cost of learning the method. Five patients with unstable pelvic fractures; were treated by percutaneous sacroiliac fixation. This reliable and useful method in the stabilization of unstable pelvic fractures...

Infection of orthopedic devices is a major complication in the postsurgical period generating important health issues and economic consequences. Prevention strategies could be based on local release of antibiotics from the orthopedic device itself to avoid adhesion and growth of bacteria. The purpose of this work is to demonstrate the efficiency to prevent these infections by a cefazolin-eluting, perforated stainless steel implant in an in vivo ovine model. The device was placed in the tibia of sheep, one group receiving cefazolin-loaded implants whereas the control group received empty implants...

Pelvic ring fractures occur in association with potentially fatal lesions, whose treatment is a priority in the polytrauma setting. As consequence, the definitive orthopedic approach may be postponed, leading patients to chronic and potentially disabling deformities. The treatment of these deformities is a challenge, requiring highly complex and staged surgical reconstructions. The ilioinguinal approach has been widely used in these surgeries, because it allows the release and mobilization of the hemipelvis and, in some cases, anterior fixation of the sacroiliac joint...

Perioperative blood loss after total knee arthroplasty (TKA) affects postoperative recovery. Tranexamic acid is safe and efficient in reducing blood loss without increasing thromboembolic events. Epsilon-aminocaproic acid (ε-ACA) is less expensive than and as safe as tranexamic acid. Its efficiency when locally applied in TKA is unknown. The authors retrospectively followed 240 consecutive patients treated by 1 surgeon with TKA from January 2012 to August 2016. From January 2013 to May 2015, the authors topically applied 5 g of ε-ACA to the open wound after tourniquet release and before closure (ε-ACA-after-tourniquet-release group)...

A Tinel's sign, a percussion-induced, painful sensation, has been reported as the most useful sign for diagnosing a schwannoma. On magnetic resonance imaging, schwannomas often exhibit a split fat sign and a target sign. The typical treatment for schwannomas is surgical excision; however, excision often results in high rates of neurological deficit. The authors retrospectively reviewed 20 patients who underwent excision of a schwannoma from 2007 to 2015. Twenty patients presented with a split fat sign and 12 patients presented with a Tinel's sign on magnetic resonance imaging...

Neer type II distal clavicle fractures are inherently unstable. The purpose of this study was to review the outcome of Neer type II distal clavicle fractures arthroscopically treated using a suspensory cortical button technique. Between 2008 and 2012, a total of 17 Neer type IIB fractures were managed operatively at the authors' institution. Functional outcomes were assessed using the pain score, the Disabilities of the Arm, Shoulder and Hand score, the Penn Shoulder Score, and the American Shoulder and Elbow Surgeons score...

This study was conducted to determine whether proximal humerus fracture patterns as defined by the Orthopaedic Trauma Association (AO/OTA) classification and the Neer 4-part system predicted functional outcomes for patients treated with open reduction and internal fixation with locked plates and, if so, which system correlated better with outcomes. During a 12-year period, 213 patients with a displaced proximal humerus fracture who underwent surgical treatment with a locking plate at 1 academic institution were prospectively followed...

Current surgical treatment of acetabular fractures is open reduction and internal fixation and requires a large incision resulting in considerable blood loss and a potentially long duration of recovery. We report a case of an acetabular fracture that received laparoscopic internal fixation after three-dimensional (3D) modelling and printing of the acetabulum. A 43 year old male fell from a height of 3 m resulting in a right acetabulum anterior column fracture. Thin section computed tomography scanning with 0...

OBJECTIVE Neurogenic kyphoscoliosis in pediatric patients has varied causes and diverse management options. The most common management strategy is to stage the orthopedic and neurosurgical aspects of the correction at an interval of 3-6 months from each other. The aim of this study was to report the authors' experience with correction of deformity in children with associated neurological abnormalities requiring intervention as a single-stage surgical treatment. METHODS Of 591 pediatric patients with scoliosis treated at the Amrita Institute of Medical Sciences and Research Centre between January 2001 and January 2011, the authors identified all patients with neurogenic kyphoscoliosis who underwent deformity correction and a neurosurgical procedure in the same surgical session when they were younger than 15 years...

To improve orthopedic implant fixation and reduce post-operative complications, osteogenic molecules are delivered locally by immobilizing them on the surface of implants, which will modulate the biology of cell attachment and differentiation on the implant surface. Estradiol, a natural steroid hormone, maintains bone metabolism by decreasing bone resorption. It either directly or indirectly affects osteoclasts. In this work, estradiol was immobilized on a titanium surface by polydopamine adlayer. Immobilization of estradiol was confirmed by X-ray electron spectroscopy (XPS), immunofluorescence staining and enzyme-linked immunosorbent assay (ELISA)...

Total hip arthroplasty (THA) is generally considered to be one of the most successful orthopedic surgical procedures. THA patients continue to experience symptoms, most commonly pain, which prevent their return to full function and activity. Possible causes include failure of fixation, instability and damage to soft tissues, associated with the trauma of the surgical procedure. Choosing the optimal surgical approach can minimize these risks and therefore improve the outcome of THA. Surgical approaches in THA include anterior, lateral [anterolateral (Hardinge) and direct lateral (Watson-Jones)], posterior (posterolateral and posterior) and posterior-2 techniques...
