Introduction Periprosthetic joint infection (PJI) is one of the most challenging and frequent complications after lower-extremity (hip knee) arthroplasty. However, there no single accepted set diagnostic criteria for PJI. Various definitions have been proposed; however, none widely adopted. Furthermore, some these disagree with each other [14]. Therefore, a workgroup convened by Musculoskeletal Infection Society (MSIS) analyzed available evidence to propose new definition A summary...
Autograft, allograft, and synthetic bone graft substitute materials play an important role in reconstructive orthopaedic surgery, understanding the biologic effects of these is necessary for optimum use. Although vascularized cancellous autograft show skeletal incorporation, host morbidity limits availability. Experimental studies have confirmed immune response to allograft bone, but clinical significance this humans still unclear. Small amounts usually are remodeled completely; large...
A multicenter retrieval analysis of 231 modular hip implants was done to investigate the effects material combination, metallurgic condition, flexural rigidity, head and neck moment arm, length, implantation time on corrosion fretting taper surfaces. Scores for were assigned medial, lateral, anterior, posterior quadrants necks, proximal distal regions heads. Neck scores found be significantly higher mixed alloy versus similar couples. Moderate severe observed in 28% heads couples 42%...

No preferred test for diagnosis of periprosthetic joint infection exists, and the algorithm workup patients suspected remains unclear. The work group evaluated available literature to determine role each diagnostic modality devise a practical that allows physicians reach infection. Ten 15 recommendations have strong or moderate evidence in support. These include matters involving erythrocyte sedimentation rate C-reactive protein level testing, knee hip aspiration, stopping use antibiotics...
The objective of this study was to investigate the characteristics, treatment and prognosis early versus late recurrence intrahepatic cholangiocarcinoma (ICC) after hepatic resection.Patients who underwent resection with curative intent for ICC were identified from a multi-institutional database. Data on clinicopathological initial operative details, timing sites recurrence, management long-term outcomes analysed.A total 933 patients included. With median follow-up 22 months, 685 (73·4 per...
It is often difficult to achieve stable fixation of a comminuted fracture associated with metaphyseal defect. The injection resorbable cement into an osseous defect may help stabilize the and maintain integrity as resorbed replaced by bone. purpose present study was evaluate repair after treatment injectable calcium-phosphate cement.The undergoes isothermic curing in vivo form carbonated apatite (dahllite) compressive strength twenty-five megapascals. Either or allograft bone placed proximal...
Plasma-sprayed coating of hydroxyapatite are biocompatible and, because their osteoconductive properties, may contribute to the early fixation total joint prostheses. To evaluate this interface, we histologically analyzed five hydroxyapatite-coated femoral stems which, along with surrounding bone, were retrieved from three humans at autopsy. The components had been in situ for a mean duration twelve months (range, almost twenty-five months) and inserted osteonecrosis (two), osteoarthrosis as...
Particles of wear debris have been implicated in osteolysis around and aseptic loosening total joint prostheses, but the number size distribution particles present periprosthetic tissues are unknown. A method particle assay was developed, consisting nitric-acid digestion tissue followed by collection particles, electronic quantitation, parallel morphological chemical characterization. Nitric acid had minimum deleterious effects on control samples titanium, cobalt-chromium alloy, polyethylene...

The purpose of this study was to examine the effect initial tensioning on outcome reconstruction ACL. ACLs 15 adult mongrel dogs were excised and reconstructed. In first five dogs, both knees reconstructed using medial one- third patellar tendon. graft fixed under a tension 1 N (0.22 pounds) in one knee 39 (8.8 opposite knee. remainder reconstructions augmented with Dacron prostheses. Tensioning compo nents either contralateral or disproportionate tensions applied autogenous material...
The findings of radiographic studies have suggested that the cementing an implant with a polished tapered stem into bed impacted bone allograft may provide adequate function joint and restore in proximal part femur. However, radiographs hips cancellous graft adjacent to cement are difficult interpret, viability is its capability for remodeling unclear. To evaluate this interface further, we obtained biopsy specimens from femur at time removal trochanteric wires four patients eleven...
In a review of 29 cases solitary and multicentric hemangioendothelial sarcomas bone, 14 were found to have histologic features epithelioid hemangioendotheliomas. These characterized by the presence or "histiocytoid" endothelial cells that either round spindle-shaped. Intracytoplasmic vacuolization was noted, some showed nesting cells, mimicking metastatic adenocarcinoma. The myxoid matrix suggested diagnosis chondrosarcoma in cases. Some tumors strongly resembled lesions formerly designated...
Abstract Polymer composites are being recognized as important implant materials for fracture fixation plates. The use of a composite material is dependent upon the mechanical properties and its biocompatibility. primary objective this project was to evaluate 30% chopped‐carbon‐fiber‐reinforced poly(etherether‐ ketone) (CFRPEEK) potential plate. A two‐ phase study conducted. first analyzed short‐term biocom‐patibility CFRPEEK through rabbit muscle testing. exhibited nonspecific foreign body...
