BACKGROUND: As revision implants and techniques have evolved and improved, understanding why contemporary revision total hip arthroplasties (THAs) fail is important to direct further improvement and innovation. As such, the goals of this study are to determine the implant survivorship of contemporary revision THAs, as well as the most common indications for re-revision. METHODS: We retrospectively reviewed 2589 aseptic revision THAs completed at our academic institution between 2005 and 2015 through our total joint registry...

INTRODUCTION: Interprosthetic fractures occur between a total knee replacement and a femoral stem of either a hemiarthroplasty or total hip replacement. The number of interprosthetic fractures will increase as the number of joint replacements rises. There is currently a paucity of literature looking at the outcomes of interprosthetic fractures. Therefore, we performed a retrospective study to: (1) determine fracture union in patients following surgical treatment of a femoral interprosthetic fracture, (2) measure outcomes included mortality and complications...

Prosthetic joint infection (PJI) is a rare but challenging complication of arthroplasty. Herein, we describe the epidemiology and microbiology of PJI, with a focus on analyzing differences between the microbiology of polymicrobial versus monomicrobial infection of hip, knee, and shoulder prostheses. In addition, we report the most frequent co-pathogens in polymicrobial infections, as detected by culture. A total of 373 patients diagnosed with PJI at Mayo Clinic were studied. For hip and knee arthroplasties, a higher proportion of fractures (P = 0...

Pelvic osteolysis induced by particulate debris derived from bearing surfaces is a well-known complication following total hip arthroplasty (THA). Atraumatic fractures of the greater trochanter (GT) associated with osteolytic lesions have been occasionally described. We present a case of a 71-year-old male patient who sustained an undisplaced fracture of the GT nine years following cementless metal-on-polyethylene THA. The fracture occurred through a 2.5-cm large osteolytic area, and no hip trauma was recorded...

RATIONALE: As survival prospects improve for long-term patients with hemodialysis, it is common for patients to exhaust all upper extremity access options before other avenues need exploration. The purpose of this case report was to describe our experience in creating a prosthetic graft between left femoral artery and right femoral vein in a patient with history of central venous occlusion and bilateral femoral neck fracture. PATIENT CONCERNS: A female patient with hemodialysis exhausted all upper extremity access options along with bilateral femoral neck fracture...

OBJECTIVES: The aim of this prospective pilot study was to evaluate the concept of one single implant placed in the edentulous mandible to retain a complete denture with regard to implant survival and prosthodontic maintenance over an observation period of 10 years. MATERIALS AND METHODS: Eleven edentulous patients were included and received one implant in the midline of the mandible. Five implants healed submerge and were uncovered 2 months later. The other six healed un-submerged and were provided with a healing abutment 4 mm in height thus moderately loaded...

BACKGROUND: Patients with pain and disability due to a prior failed shoulder arthroplasty with associated proximal humeral bone loss have limited reconstruction options. Our purpose was to report the results of a large cohort of patients treated with a reverse shoulder allograft-prosthetic composite (APC). METHODS: Between 2002 and 2012, a total of 73 patients were treated with a reverse shoulder APC and had adequate follow-up. Clinical outcome scores, range of motion, and radiographic evidence of failure were assessed...

There is an increasing incidence of proximal humerus fractures. Patients with proximal humerus fractures have traditionally been treated conservatively. During the past decades, however, various new osteosynthetic and prosthetic implants have been developed for the shoulder and surgical treatment of proximal humerus fractures has increased. However, recent literature in which conservative and surgical treatment of proximal humerus fractures is compared has shown no difference in functional outcome. The trend towards more frequent surgical treatment is thus not based on scientific evidence...

INTRODUCTION: We report 5- to 10-year clinical and radiological outcomes of a series of uncemented Oxinium on Verilast (highly cross-linked polyethylene liners) total hip replacements (THAs) using the Anthology stem and R3/Reflection cup system. METHODS: 116 THAs were performed by 2 senior authors in 104 patients from 2005 to 2009. The mean age at time of operation was 63.8 (45-80) years. The average length of follow-up was 8.8 years. At final data collection 12 patients had died (13 THAs) and 3 patients (3 THAs) were lost to follow-up...

Prosthesis-patient mismatch (PPM) occurs when the effective orifice area (EOA) of the prosthetic valve is too small in relation to a patient's body size, thus resulting in high residual postoperative pressure gradients across the prosthesis. Severe PPM occurs in 2% to 20% of patients undergoing surgical aortic valve replacement (AVR) and is associated with 1.5- to 2.0-fold increase in the risk of mortality and heart failure rehospitalization. The purpose of this article is to present an overview of the role of multimodality imaging in the assessment, prediction, prevention, and management of PPM following AVR...

INTRODUCTION: Cirrhotic patients are at a higher risk for sustaining orthopedic fractures with a reported prevalence of 5% to 20%. Cirrhosis also affects wound healing and bleeding risk, and hence, impacts the postoperative outcomes after fracture repair. However, there is limited data available on the postoperative risk factors and clinical outcomes of fractures in patients with chronic liver disease (CLD). METHODS: Data from the National Inpatient Sample for the years 2012 to 2015 were analyzed...

PURPOSE: Dislocation and peri-prosthetic fracture (PPF) are major reasons for revision THA (total hip arthroplasty). The main advantage of dual mobility (DM) cups is to minimize the incidence of dislocation compared to single mobility (SM) cups. We hypothesized that the use of DM would lead to an increased risk of PPF because of its greater stability. In contrast, standard cups would be at higher risk of dislocation. METHODS: A retrospective comparative study was performed in our institution including 126 revision THAs between January 2013 and December 2017...

Traumatic head injuries can be associated with ossicular chain disruption. Especially in the setting of temporal bone fractures, proper alignment of the ossicular chain has to be insured. Loss of normal ossicular alignment is associated with conductive hearing loss. Treatment of ossicular chain disruption, so called ossiculoplasty, aims to restore proper anatomic alignment of the ossicles with osseous or cartilaginous autograft and/or prosthetic devices.
