Bone infection and nonunion are the main orthopedic and traumatic complications whose treatment remains a challenge because multiple factors are involved in the rate of failures when you try to correct them. Knowing these factors were the problem that caused the research through a prospective longitudinal study of 83 patients of 43.3 ± 16.1 years old. They were treated for aseptic and septic nonunion, osteomyelitis, osteitis, malunion or infected joint replacement. The cases were classified with or without postoperative complications and outcome related to systemic and local factors taken prognostic model Cierny-Mader as factors affecting immune surveillance, metabolism and local vascularization...

BACKGROUND: Monitoring the adequacy of spontaneous breathing is a major patient safety concern in the post-operative setting. Monitoring is particularly important for obese patients, who are at a higher risk for post-surgical respiratory complications and often have increased metabolic demand due to excess weight. Here we used a novel, noninvasive Respiratory Volume Monitor (RVM) to monitor ventilation in both obese and non-obese orthopedic patients throughout their perioperative course, in order to develop better monitoring strategies...

BACKGROUND: In an effort to control rising healthcare costs, healthcare reforms have developed initiatives to evaluate the efficacy of alternative payment models (APMs) for Medicare reimbursements. The Center for Medicare and Medicaid Services Innovation Center (CMMSIC) introduced the voluntary Bundled Payments for Care Improvement (BPCI) model experiment as a means to curtail Medicare cost by allotting a fixed payment for an episode of care. The purpose of this review is to (1) summarize the preliminary clinical results of the BPCI and (2) discuss how it has led to other healthcare reforms and alternative payment models...

BACKGROUND: Pressure irrigation of surgical incisions and traumatic wounds is commonly used to prevent infections. Commercial pressure irrigation devices have proliferated rapidly, but scientific validation of clinical benefit or appropriate use remains uncertain. METHODS: The published experimental and clinical investigations of pressure irrigation have been reviewed since the introduction of the Waterpik device in 1967 to identify the evidence for use to prevent soft tissue infections associated with injury wounds or surgical incisions...

Senescent cells (SnCs) accumulate in many vertebrate tissues with age and contribute to age-related pathologies, presumably through their secretion of factors contributing to the senescence-associated secretory phenotype (SASP). Removal of SnCs delays several pathologies and increases healthy lifespan. Aging and trauma are risk factors for the development of osteoarthritis (OA), a chronic disease characterized by degeneration of articular cartilage leading to pain and physical disability. Senescent chondrocytes are found in cartilage tissue isolated from patients undergoing joint replacement surgery, yet their role in disease pathogenesis is unknown...

INTRODUCTION: Worldwide estimates are that 9.6% of men and 18.0% of women aged over 60 years have symptomatic osteoarthritis. The current treatment options vary from conservative to joint replacement. Recently, debridement of the joint has become an option for symptomatic relief. We evaluated the outcome of arthroscopic debridement with autologous conditioned plasma. The latter helps to promote cellular repair. We have evaluated our results over a two year period. MATERIALS AND METHODS: We retrospectively analyzed a cohort of 52 patients who underwent arthroscopic knee debridement with autologous conditioned plasma in 2011...

STUDY DESIGN: A retrospective cohort study with prospectively collected data OBJECTIVE.: The aim of this study was to compare SSI incidences, the cost of hand hygiene agents, and hand hygiene time between the traditional hand scrub and the waterless hand rub protocols before orthopaedic surgery. SUMMARY OF BACKGROUND DATA: Surgical-site-infections (SSI) prolong hospitalization and are a leading nosocomial cause of morbidity as well as a source of excess cost. Recently, a waterless hand rub protocol comprising alcohol based chlorhexidine gluconate for use before surgery was developed, but no studies have yet examined its utility in orthopaedic surgery...

BACKGROUND: The surgical options for revision shoulder arthroplasty and the number of procedures performed are increasing. However, little is known about the risk factors for intraoperative complications associated with this complex surgery. METHODS: The National Joint Registry (NJR) is a surgeon reported database recording information on major joint replacements including revision shoulder arthroplasty. Using multivariable binary logistic regression modelling, we analyzed 1445 revision shoulder arthroplasties reported to the NJR between April 2012 and 2015...

BACKGROUND: Approximately 88,000 primary hip replacements are performed in England and Wales each year. Around 1% go on to develop deep prosthetic joint infection. Between one-stage and two-stage revision arthroplasty best treatment options remain unclear. Our aims were to characterise consultant orthopaedic surgeons' decisions about performing either one-stage or two-stage revision surgery for patients with deep prosthetic infection (PJI) after hip arthroplasty, and to identify whether a randomised trial comparing one-stage with two-stage revision would be feasible...

BACKGROUND: Although resident physicians play a vital role in the US health care system, they are believed to create inefficiencies in the delivery of care. Under the regional component of the Comprehensive Care for Joint Replacement model, teaching hospitals are forced to compete on efficiency and outcomes with nonteaching hospitals. METHODS: We identified 86,021 patients undergoing elective primary total hip arthroplasty in New York State between January 1, 2009, and September 30, 2014...

Aseptic periprosthetic osteolysis is a complication induced by wear particles after hip joint replacement, which shortens the service life of prostheses. Although many methods have been applied to prevent this complication, the results were not always successful. In the present study, we explored the prophylactic effect of notoginsenoside R1 (NG-R1) on a Ti particle-induced mouse calvarial osteolysis model and the inhibitory effect on RANKL-mediated osteoclastogenesis and osteoclast bone resorption. Our results indicated that intraperitoneal injection of NG-R1(10 or 20mg/kg/day), a constituent of notoginseng, alleviates Ti particle-induced mouse calvarial osteolysis after twelve days post-treatment...

BACKGROUND: Enhanced recovery after surgery protocols for total joint replacements (TJRs) emphasize early discharge, yet the impact on readmissions is not well documented. We evaluate the impact of a one-day length of stay (LOS) discharge protocol on readmissions. METHODS: We conducted a retrospective review of all primary TJRs (hip and knee) from April 2014 to March 2015. Patients who had adequate support to be discharged home were categorized into 2 groups, 1-day (n = 174) vs 2-day (n = 285) LOS groups...

Hundreds of thousands of revision surgeries for hip, knee, and shoulder joint arthroplasties are now performed worldwide annually. Partial removal of hardware during some types of revision surgeries may create significant amounts of third body metal, polymer, or bone cement debris. Retained debris may lead to a variety of negative health effects including damage to the joint replacement. We describe a novel technique for the better containment and easier removal of third body debris during partial hardware removal...
