OBJECTIVE To determine the knowledge of Brazilian Orthopedic Surgeons on the costs of orthopedic surgical devices used in surgical implants . METHODS A questionnaire was applied to Brazilian Orthopedic Surgeons during the 46th Brazilian Congress on Orthopedics and Traumatology . RESULTS Two hundred and one Orthopedic Surgeons completely filled out the questionnaire. The difference between t...

One of the most successful techniques in restoration of degenerated joint functions is total hip replacement. This surgical approach includes removal of diseased cartilage and bone parts, and replacement by the corresponding joint prostheses. By using metal alloys, high quality plastic and polymer materials, orthopedic surgeons can reconstruct hip fractures, or replace a painful, dysfunctional ...

This paper describes orthopedic surgical planning based on the integration of RE and RP. Using symmetrical characteristics of the human body, CAD data of the original bone without damages for the injured extent are generated from a mirror transformation of undamaged bone data for the uninjured extent. The physical model before the injury is manufactured from RP apparatus. Surgical planning, suc...

BACKGROUND Rising health care costs and emphasis on value have placed the onus of reducing healthcare costs on the surgeon. METHODS Financial data from 3,973 hip, knee, and shoulder arthroplasties performed at a physician owned orthopedic hospital was retrospectively reviewed over a two-year period. A wasted implant financial report was posted starting the second year of the study. Each surge...

The failure of prosthesis after total joint replacement is due to the lack of early implant osseointegration. In this study polyvinyl alcohol-collagen-hydroxyapatite (PVA-Col-HA) electrospun nanofibrous meshes were fabricated as a biomimetic bone-like extracellular matrix for the modification of orthopedic prosthetic surfaces. In order to reinforce the PVA nanofibers, HA nanorods and Type I col...

This paper deals with detailed corrosion analysis of explanted devices. The study of total 6 different types of orthopedic metallic implant was carried out after collecting the clinical report from the doctors, who performed these implantations. The clinical report covered the purpose of implantation, body part where implantation was done, and physiological reasons of removal of implant. The me...

Orthopedic implants should have sufficient strength and promote bone tissue regeneration. However, most conventional are optimized for use either under high mechanical load or active osseointegration. To achieve the dual target of durability biocompatibility, polyether ether ketone (PEEK) filaments reinforced with internal titanium dioxide (TiO2) nanoparticles via dopamine-induced polymerizatio...

Objective: To determine the causes of orthopedic implants failure, which is being used in our setup for fixation of different fractures. Materials and Methods: The study was conducted at Orthopedic and Spine surgery unit of Hayatabad Medical Complex (HMC) Peshawar from November 2007 to May 2014. A total of 62 patients were retrospectively identified an included in the study. The inclusion crite...

BACKGROUND The aim of the present study was to investigate the safety of bioabsorbable plates and screws in humans. METHODS For this purpose, an implant system based on [poly(lactic-co-glycolic acids)(85:15)] was designed. The system was tested for pH, temperature, and swelling and then its surface morphology was analyzed for surface porosity using environmental electron microscopy. Then, the...
