Xiangping Luo, Shengmao He, Dingshi Zeng, Lijun Lin, Qi Li
BACKGROUND: Primary hemiarthroplasty was recommended by some surgeons as the preferred choice in treating unstable senile intertrochanteric fractures with osteoporosis. However, many studies reported that proximal femoral nail antirotation (PFNA) currently was as an optimal implant for the treatment of different type of intertrochanteric fractures. Which method is better for treating senile intertrochanteric fractures remains controversial due to the insufficient clinical evidences. METHODS: We reviewed all consecutive senile intertrochanteric fractures treated with PFNA or cemented hemiarthroplasty at our institution between July 2010 and March 2015...

INTRODUCTION: The operative management of tibial plateau fractures is challenging and post-operative complications do occur. The purpose of this study was three-fold. 1). To report complications and unplanned outcomes in patients who had sustained tibial plateau fractures and were operatively managed 2). To report predictors of these post-operative events 3). To report if differences in clinical outcomes exist in patients who sustained a post-operative event. METHODS: Over 11 years, all tibial plateau fractures were prospectively followed...

PURPOSE: In recent times the direct anterior approach for total hip replacement has gained considerable interest among orthopaedic surgeons because of the relative muscle-sparing nature than other surgical approaches. However, critics believe that this approach is associated with steep learning curve and high complication rates, mainly attributed to a more limited exposure to the femur. In order to make femoral access easier and implantation of acetabulum in anatomic plane, we designed a "two incisions anterior approach technique" for total hip replacement...

There has been a dramatic increase in the emergence of antibiotic resistant bacterial strains, which has made antibiotic choices for infection control increasingly limited and more expensive. In the U.S. alone, antibiotic resistant bacteria cause at least 2 million infections and 23,000 deaths a year resulting in a $55-70 billion per year economic impact. Antibiotics are critical to the success of surgical procedures including orthopaedic prosthetic surgeries, and antibiotic resistance is occurring in nearly all bacteria that infect people, including the most common bacteria that cause orthopaedic infections, such as Staphylococcus aureus (S...

BACKGROUND: Ankle fractures are frequently occurring injuries. Despite the relatively simple operative technique, patients often suffer from postoperative complications. Little is known about postoperative treatment of implant-associated infections of the ankle. Therefore, this study shows and evaluates a treatment algorithm in long- and short-term outcomes compared to infection-free patients. METHODS: Data from patients of over 20 years of a level 1 trauma center and university hospital was retrospectively analyzed including age, gender, comorbidities, smoking status, fracture classification, number of revisions, length of in-patient stay due to fracture and infection, and results of microbiological specimen with the length of antibiotic treatment...

BACKGROUND: Surgical site infection in orthopaedic implants is a major problem, causing long hospital stay, cost to the patient and is a burden on health care facilities. It increases rate of nonunion, osteomyelitis, implant failure, sepsis, multiorgan dysfunction and even death. Surgical site infection is defined as pain, erythema, swelling and discharge from wound site. Surgical site infection in orthopaedic implants is more challenging to the treating orthopaedic surgeon as the causative organism is protected by a biofilm over the implant's surface...

Motion at the bone-implant interface, following primary or revision knee arthroplasty, can be detrimental to the long term survival of the implant. This study employs experimentally verified computational models of the distal femur to characterise the relative motion at the bone-implant interface for three different implant types; a posterior stabilising implant (PS), a total stabilising implant (TS) with short stem (12mm x 50mm), and a total stabilising implant (TS) with long offset stem (19mm x 150mm with a 4mm lateral offset)...

INTRODUCTION: Total hip arthroplasty (THA) is a very successful procedure. Revision THA is becoming increasingly common. Recent developments to improve outcomes include the development of large trabecular metal (TM) acetabular cups and augments. There is a paucity of data on the benefit of these new techniques. METHODS: A single-centre retrospective review consisting of a radiological review of post-op revision THA anteroposterior pelvis. Data collection was performed using the Irish National Orthopaedic Register (INOR) and from a previous project...

Total joint replacement comes with a high success rate and has been shown to have a very positive impact on our patients suffering from arthritis. Against all efforts about 2 % of our patients will suffer an implant related infection. As the treatment of infected arthroplasties is difficult and expensive the knowledge of risk factors is becoming more and more important for the treatment team in order to improve our preventive measures. Prevention must be performed pre-, intra- and postoperatively. Preoperative optimization of blood sugar levels, nutritional status and correction of general anaemia for example are paramount and the general practitioner as well as the surgeon should be aware of these and other modifiable risk factors in order to operate on the patient in the best possible conditions...

The prevention of implant-associated infection, one the most feared complications in orthopaedic surgery, remains a major clinical challenge and urges development of effective methods to prevent bacterial colonization of implanted devices. Alpha-helical antimicrobial peptides (AMPs) may be promising candidates in this respect due to their potent and broad-spectrum antimicrobial activity, their low tendency to elicit resistance and possible retention of efficacy in the immobilized state. The aim of this study was to evaluate the potential of five different helical AMPs, the cathelicidins BMAP-27 and BMAP-28, their (1-18) fragments and the rationally designed, artificial P19(9/G7) peptide, for the prevention of orthopaedic implant infections...

A large cartilage lesion of the tibial plateau with a deficient meniscus in a young patient is a challenging pathology for the orthopaedic surgeon due to the limited options available. While hemiarthroplasty procedures can be an option, the risk of revision in a young patient is high, and therefore a reconstructive procedure is advocated. The purpose of this Technical Note is to describe our technique for tibial plateau resurfacing, including the preparation and implantation of a medial tibial plateau and medial meniscal allograft, in a patient with a post-traumatic KD-4 knee dislocation with a medial tibial plateau rim fracture, medial meniscus deficiency, and medial tibiofemoral joint subluxation...

BACKGROUND: Spinal brucellosis is a less commonly reported infectious spinal pathology. There are few reports regarding the surgical treatment of spinal brucellosis in existing literature. This retrospective study was conducted to determine the effectiveness of single-stage transforaminal decompression, debridement, interbody fusion, and posterior instrumentation for lumbosacral spinal brucellosis. METHODS: From February 2012 to April 2015, 32 consecutive patients (19 males and 13 females, mean age 53...

Implant-associated infections are notoriously difficult to treat and may even result in amputation and death. The first few days after surgery is the most critical time to prevent those infections preferably through full eradication of the micro-organisms entering the body peri-operatively. That is particularly important for patients with a compromised immune system such as orthopaedic oncologic patients, as they are at higher risk for infection and complications. Full eradication of bacteria is, especially in a biofilm, extremely challenging due to the toxicity barrier that prevents us from delivering high doses of antibacterial agents...

Nowadays, salt consumption appears to be drastically above the recommended level in industrialized countries. The health consequences of this overconsumption are heavy since high-salt intake induces cardiovascular disease, kidney dysfunction, and stroke. Moreover, harmful interaction may also occur with orthopaedic devices because overconsumption of salt reinforces the corrosive aspect of biological tissues and favors bone resorption process. In the present study, we aimed to assess the in vivo effect of three weeks of a high-salt diet, associated (or not) with two weeks of the neuro-myoelectrostimulation (NMES) rehabilitation program on the biocompatibility of four biomaterials used in the manufacture of arthroplasty implants...

BACKGROUND: Infection remains a leading cause of failure of hip and knee replacements. Infection burden is the ratio of implants revised for infection to the total number of arthroplasties in a specific period, measuring the steady state of infection in a registry. We hypothesized infection burden would be similar among arthroplasty registries. METHODS: We evaluated publicly reported data from 6 arthroplasty registries (Australian Orthopaedic Association National Joint Replacement Registry [AOANJRR], New Zealand Joint Registry, Swedish Hip Arthroplasty Register, Swedish Knee Arthroplasty Register, National Joint Registry of England, Wales, Northern Ireland, and the Isle of Man, and the American Joint Replacement Registry) for revisions performed with an infection diagnosis over the last 6 years...

In 1979, Pulsed electromagnetic fields (PEMFs) were approved by the Food and Drug Administration as an effective method in the treatment of non-unions. As well as PEMFs, also static magnetic fields (SMFs) have been widely investigated in orthopaedic studies. Even if the exact mechanism of action is not well understood, a large number of studies showed specific effects both at cellular and tissue levels. As bone fracture healing and osseointegration share the same biological events, the application of magnetic field stimulation in order to facilitate the osseointegration process has been suggested...

BACKGROUND: While glenoid retroversion and posterior humeral head decentering are common preoperative features of severely arthritic glenohumeral joints, the relationship of postoperative glenoid component retroversion to the clinical results of total shoulder arthroplasty (TSA) is unclear. Studies have indicated concern for inferior outcomes when glenoid components are inserted in 15° or more retroversion. QUESTIONS/PURPOSES: In a population of patients undergoing TSA in whom no specific efforts were made to change the version of the glenoid, we asked whether at 2 years after surgery patients having glenoid components implanted in 15° or greater retroversion had (1) less improvement in the Simple Shoulder Test (SST) score and lower SST scores; (2) higher percentages of central peg lucency, higher Lazarus radiolucency grades, higher mean percentages of posterior decentering, and more frequent central peg perforation; or (3) a greater percentage having revision for glenoid component failure compared with patients with glenoid components implanted in less than 15° retroversion...

OBJECTIVE: In orthopaedics, novel bioactive composites are largely needed to improve the synthetic achievement of the implants. In this work, semiconducting metal oxides such as SiO2, TiO2, and ZrO2 particles (Ps) were used individually and in different ratios to obtain different biphasic composites. The immunotoxicity of these composites was tested to inspect the potential toxicity prior to their use in further medical applications. MATERIALS AND METHODS: In vitro mineralisation ability was inspected by soaking the composites in simulated body fluid (SBF)...

Distal fibula fractures represent a common problem in orthopaedics. When fibula fractures require operative fixation, implants are typically made from stainless steel or titanium alloys. Carbon fiber implants have been used elsewhere in orthopaedics for years, and their advantages include a modulus of elasticity similar to that of bone, biocompatibility, increased fatigue strength, and radiolucency. This study hypothesized that carbon fiber plates would provide similar outcomes for ankle fracture fixation as titanium and steel implants...
