Revision total knee arthroplasty (TKA) can be challenging in the setting of bone loss. Previously, severe bone loss was managed with impaction grafting and structural allografts; however, these had limited success. Recently, metaphyseal cones have been developed as useful adjuncts with good early outcomes. Presently, there are no published guidelines on how to preoperatively predict the need for metaphyseal cone implantation radiographically. Therefore, the purpose of this study was to evaluate how well preoperative radiographs were able to predict the use of cones in a small series of patients undergoing revision TKA...

BACKGROUND: Previous studies have shown that adequate thickness or initial augmentation of soft tissue has a positive effect on the stability of peri-implant bone. This randomized, controlled trial aimed to evaluate the influence of augmenting soft tissue with platelet-rich fibrin (PRF) on crestal bone and soft tissue around implants. METHODS: After randomization, 31 fully threaded titanium implants were inserted in 31 patients (16 men and 15 women) in the lower mandible using a split-flap technique...

Exhaustion of superficial veins coupled with the presence of intrathoracic central venous occlusions remains a significant obstacle for hemodialysis access creation; complex arteriovenous graft (AVG) configurations have been described. The axillary-iliac AVG was first reported in 1987, and few authors have explored this access. We evaluated our experience with this AVG configuration utilizing the early cannulation (EC) graft Flixene™ (Atrium ™, Hudson, NH, USA). Eight patients (75 % men; mean age 37 ± 10 years) with End-Stage Renal Disease (ESRD) underwent axillo-iliac AVG creation with Flixene™ grafts; all had exhausted peripheral veins, occluded thoracic central veins, and inadequate femoral veins...

INTRODUCTION: Available literature suggests there is a transient drop in implant stability from approximately week 0 to week 3-4 as a result of peri-implant bone remodeling as it transitions from a primary, mechanical stability to a secondary, biological stability. Research investigating the influence of macro-thread design on this process is scant. AIM: The specific aim of this study was to evaluate the role of macro-thread design on implant stability in the early post-operative healing period using resonance frequency analysis (RFA)...

With the advent of the skin sparing mastectomy, immediate breast reconstruction with placement of the definitive prosthesis at the time of mastectomy is possible. The question remains: does single-stage prosthetic reconstruction result in greater numbers of complications or rates of re-operation, compared to two-stage tissue expander reconstruction? A retrospective cohort study of a single centre?s experience with these techniques was carried out. From 2004 to 2012, 54 cases of immediate breast reconstruction with implant were identified, and 108 cases of immediate breast reconstruction using a tissue expander were identified...

BACKGROUND: Heart disease is a major cause of death in industrialized nations, with approximately 50% of these deaths attributable to sudden cardiac arrest. If patients at high risk for sudden cardiac arrest can be identified, their odds of surviving fatal arrhythmias can be significantly improved through prophylactic implantable cardioverter defibrillator placement. This review summarizes the current knowledge pertaining to surface electrocardiogram (ECG) predictors of sudden cardiac arrest...
