INTRODUCTION: Periprosthetic femoral fractures (PFF) around tumor prosthesis of knee are stubborn problems for surgeons, huge bone defect and inappropriate biomechanics of the revision implant design can be disaster for reconstruction. With the development of three-dimensional (3D) printing technology, surgeons participate more in precise preoperative design and simulation for treatment of such fractures. In this study we explored an accurate and feasible way to restore normal anatomy and function of the knee joint with 3D printing technology...

BACKGROUND: Bony increased-offset reverse shoulder arthroplasty (BIO-RSA) may address issues such as inferior scapular notching, prosthetic instability and limited postoperative shoulder rotation; all of which have been reported with the standard RSA and attributed to the medialized design. We hypothesised that this lateralization may increase the rate of scapular stress fractures. METHODS: A retrospective review of prospectively collected data was performed on patients who had undergone a RSA between January 2013 and October 2016...

Full-coverage restorations represent a well-known rehabilitation strategy for compromised posterior teeth; in the last years, new ceramic materials like zirconia have been introduced and widely adopted for the prosthetic management of molar and premolar areas. A long-term follow-up of a maxillary premolar rehabilitation using a veneered zirconia crown is presented; after ten years of uneventful clinical service of the tooth-restoration complex, a serious complication-namely, a vertical root fracture (VRF)-occurred...

Traditional above-the-knee amputation prosthetics utilize a stump-socket interface that is well-known for skin/socket problems, sitting difficulty, disuse osteopenia, and increased work of ambulation. As a result, we evaluated a novel osseointegrated transcutaneous implant in a large animal. The implant was designed to promote osseointegration at the bone-implant interface and minimize complications. As proof of concept, four Dorset sheep underwent a two-stage surgery for forelimb placement of an osseointegrated transcutaneous implant utilizing Compress® technology (Biomet, Inc...

BACKGROUND: The effect of bone mineral density (BMD) on outcomes from total ankle arthroplasty (TAA) has not been studied. BMD can be estimated by measuring Hounsfield units (HU) on standard computed tomography (CT), which is frequently performed prior to TAA. We aimed to identify whether tibial and talar HU measured from preoperative CT scans were associated with periprosthetic fracture or revision risk in patients undergoing TAA. METHODS: A prospectively collected database was used to retrospectively screen all patients undergoing primary TAA...

Radial head fractures may commonly be treated by (1) open reduction and internal fixation (ORIF), (2) radial head excision, or (3) radial head replacement. If there is no associated elbow instability with lateral ulnar collateral ligament (LUCL) injury, the preferred approach is via a split in the extensor digitorum communis (EDC) origin. This provides a wide exposure but limits the risk of injury to the LUCL and associated instability. The radial head is fixed, excised, or replaced. Open treatment of radial head fractures begins with the following steps: (1) a laterally based incision is centered over the radiocapitellar joint, (2) the EDC is split at the midline of the radial head and elevated off the bone anteriorly and superiorly, and dissection proceeds distally, splitting the extensor origin along its fibers, and (3) the capsule is opened and the radial head fracture, identified...

PURPOSE: Dexamethasone has been shown to prevent post-operative nausea and vomiting (PONV) and seems to reduce post-operative pain. Both factors, which can extend the hospital stay, delay rehabilitation, and impact patient satisfaction. Because of the immunosuppressive and glucose-rising effects of dexamethasone, there has been concern of its safety in arthroplasty surgery. The purpose of our study was to examine infection safety of dexamethasone in arthroplasty surgery with enough large study material to reliably detect a possible, even small, difference in infection incidence...

INTRODUCTION: Total knee arthroplasty (TKA) is increasingly being performed. Distal femur periprosthetic fracture is a potentially catastrophic complication following TKA and existing data document substantial distal femur bone mineral density (BMD) loss following TKA. However, distal femur BMD is virtually never measured clinically as no consensus approach exists. This pilot study's purpose was to define regional BMD variation throughout the femur, suggest standard dual-energy X-ray absorptiometry (DXA) regions of interest (ROIs) and evaluate BMD reproducibility at these ROIs...

Hip fractures are common in elderly patients, and which surgical modality to pursue is often debated. Malnutrition, which cannot be corrected preoperatively in this population, is often not considered. Therefore, the authors sought to investigate the association between hypoalbuminemia and postoperative outcomes based on surgical intervention. Patients undergoing arthroplasty (hemiarthroplasty or total hip arthroplasty), open reduction and internal fixation, and intramedullary nailing placement for treatment of hip fractures were identified in the American College of Surgeons National Surgical Quality Improvement Program database...

INTRODUCTION: Hydatid disease in humans caused by the parasitic tapeworm Echinococcus granulosus has an osseous involvement of about 0.5%-2.5% of all cases in humans. The location of hydatid cysts in the tibia is seldom described in the medical literature, and its diagnosis and treatment is challenging. CASE REPORT: This paper presents a patient, with a long term, well tolerated, bilateral total knee arthroplasty (TKA), treated at our clinic, with a recent history of pain and oedema in her left upper leg...

Ceramic based prosthetic materials have been used in dental restorations due to their excellent aesthetic and biocompatibility. However, due to concerns related to their mechanical properties and abrasive action against natural teeth, a proper selection of these materials is crucial to preserve the occlusal interactions and prevent abnormal dental wear. The aim of this work is to compare the wear performance of Vita Enamic®, a polymer infiltrated ceramic (PIC), with that of other three commercial ceramic based dental materials - Zirconia, Leucite and Zirconia Veneered - when tested against natural teeth...

BACKGROUND: Management of fragility fractures of the ankle is challenging. Non-operative treatment often requires significant periods of reduced weight bearing. Operative fixation is difficult due to osteoporotic bone and poor soft tissues. The aim of this study was to review the initial experience of treating unstable ankle fractures with a retrograde femoral nail used as a long tibiotalocalcaneal nail. PATIENTS AND METHODS: Sixteen patients were treated from January 2014 until November 2017...

INTRODUCTION: Periprosthetic hip fractures are those that occur at the femoral and acetabular level. These fractures are associated with a wide variety of problems such as comminution, loose of bone stock and loosening of the femoral stem. Treatment of these fractures has historically been associated with high rates of treatment failures, complications and unsatisfactory outcomes. OBJECTIVE: To present the clinical-radiographic case of the treatment of a periprosthetic hip fracture, with a femoral revision and metaphyseal reconstruction with cortical strut allograft and cerclage cables, in a multioperated patient...

BACKGROUND: Infection and instability are the complications of prosthetic shoulder surgery of more difficult management. Instability builds up to half of the cases, while the fungal infection accounts for less than 1% of all and can cause severe damage to bone and soft tissue. METHODS: In this case clinical fungal infection by Candida parapsilosis is presented in a shoulder hemiarthroplasty indicated by a fracture of the proximal humerus. He received surgical treatment in two-stages and administration of fluconazole for eight weeks prior to the second surgical time...

An ageing population and increased utilisation of tissue valves in younger patients imply that the number of patients receiving transcatheter aortic valve implantation within failed bioprostheses will continue to increase. There are two major adverse events associated with aortic valve-in-valve procedures that may temper the enthusiasm for these appealing interventions. Residual stenosis is the "Achilles' heel" of aortic valve-in-valve, while coronary obstruction is an uncommon but life-threatening adverse event...

Radial head replacement should be indicated in all cases of radial head fractures when open reduction and internal fixation is anticipated to be difficult or impossible. Although excellent therapeutic results have been ob-tained, this procedure, like any other surgical procedures, may be associated with severe complications, includ-ing contractures, ossification or aseptic synovitis. In these cases, removal of the prosthetic radial head has al-ways been a safe and popular solution producing a satisfactory clinical outcome...
