Integral-Leg-Prosthesis (ILP) is a comparatively new attachment system that allows direct skeletal docking of artificial limbs. Between January 1999 and December 2013, 69 patients with transfemoral amputation were fitted with ILPs by a single German surgeon. Device design iterations and surgical techniques evolved during these years. For the purposes of comparison, patients receiving the first ...

BACKGROUND Evaluation of infection persistence during the two-stage exchange of the hip is challenging. Joint aspiration before reconstruction is supposed to rule out infection persistence. Sensitivity and specificity of synovial fluid culture and synovial leucocyte count for detecting infection persistence during the two-stage exchange of the hip were evaluated. METHODS Ninety-two aspiration...

BACKGROUND AND PURPOSE Debridement and retention of the prosthesis is often attempted to treat early prosthetic joint infection (PJI). However, previous studies have found inconsistent results, with success rates ranging from 21% to 100%, and little has been written in the literature about hip function. We have therefore analyzed the clinical and functional outcome of early PJIs treated with th...

the effect of inter-implant distance on retention and resistance of implant-tissue-supported overdentures is lacking in the literature. an in vitro study was performed to evaluate this effect for mandibular implant-tissue-supported overdentures retained by two ball attachments.an acrylic cast of an edentulous mandible was fabricated. three pairs of implants were symmetrically placed at both sid...

OBJECTIVE To evaluate whether operating room (OR) ventilation with (vertical) laminar airflow impacts on surgical site infection (SSI) rates. DESIGN Retrospective cohort-study based on routine surveillance data. PATIENTS AND METHODS Sixty-three surgical departments participating voluntarily in the German national nosocomial infections surveillance system "KISS" were included (a total of 99,...

BACKGROUND Abiotrophia species have rarely been implicated in osteoarticular infections. We report one case of an A. defectiva knee prosthesis infection. CASE PRESENTATION A 71-year-old man of Italian origin presented with pain and swelling of the knee four years after the implantation of a total knee replacement prosthesis. While standard culturing of the synovial fluid resulted in no isolat...

Expandable endoprostheses have become an acceptable modality to address the issue of limb-length inequality in limb-sparing procedures for skeletally immature patients afflicted with lower extremity bone sarcomas. This study retrospectively analyzed postoperative outcomes and complications for 7 patients (8 limbs) who underwent minimally invasive or noninvasive reconstruction during a 12-year p...

Objective: to characterize the epidemiological profile of patients undergoing hip replacement, primary or revisional. Methods: we conducted a retrospective, descriptive study, including hip arthroplasties performed from January 2009 to June 2012 in a Belo Horizonte teaching hospital, Minas Gerais State – MG, Brazil. Data were analyzed using descriptive statistics. Results: orthopedic procedures...

The average life span of knee prosthesis used in Total Knee Replacement (TKR) is approximately 10 to 15 years. Literature indicates that the reasons for implant failures include wear, infection, instability, and stiffness. However, the majority of failures are due to wear and tear of the prosthesis. The most common biopolymer used in TKR  is Ultra High Molecular Weight Polyethylene (UHMWPE). Pr...

Reverse shoulder prosthesis has become one of the most often used prosthetic implants in shoulder replacement surgery. It has a wide spectrum of indications, starting from comminuted humeral fractures and posttraumatic arthritis to arthritis caused by the rotator cuff loss. Its application at our hospital began in 2004, at first in few specific cases and with time in ever growing number of pati...
