Orthopedic implant removal is a commonly performed procedure. While implant removal can be associated withimproved symptoms, risks of the surgery are notable. Stripped screws, broken and retained hardware, and morbidityassociated with soft tissue compromise during difficult removal are all common. Familiarity with the instruments iscritical to procedure success. The purpose of...

Objective: To evaluate the importance of tip apex distance in implant failure intertrochanteric fracture femur treated with Dynamic hip screw, so that optimum should maintain to decrease DHS. Study Design: It was a descriptive cross sectional study. Setting and Duration: Patients were selected from orthopedic unit Nishtar Hospital, Multan, July 2020 June 2021. Methodology: All patients meeting ...

Bacteria belonging to the Enterobacter genus are frequently isolated from clinical samples but are unusual causative agents of orthopedic implant infections. Twelve genetic clusters (clusters I to XII) and one sequence crowd (sequence crowd xiii) can be distinguished within the Enterobacter cloacae nomenspecies on the basis of hsp60 sequence analysis, and until now, none of these clusters could...

OBJECTIVES To describe the rate of surgical site infections in children undergoing orthopedic surgery in centers of excellence and analyze the patients' profiles. METHODS Medical records of pediatric patients undergoing orthopedic surgery in the Jamil Haddad National Institute of Traumatology and Orthopedics from January 2012 to December 2013 were analyzed and monitored for one year. Patients...

The degradable polymers poly(orthoester) (POE), poly(L-lactic acid) (PLA), and the nondegradable polymers polysulfone (PSF), polyethylene (PE), and poly(ether ether ketone) (PEEK) were exposed to cultures of Staphylococcus epidermidis, Pseudomonas aeruginosa, or Escherichia coli. Bacteria washed and resuspended in phosphate buffered saline (PBS) adhered to polymers in amounts nearly twice those...

Implant-associated infection is a serious complication in orthopedic surgery, and endowing implant surfaces with antibacterial properties could be one of the most promising approaches for preventing such infection. In this study, we developed cefazolin loaded biodegradable polypeptide multilayer nanofilms on orthopedic implants. We found that the amount of cefazolin released could be tuned. A h...

For many years orthopedic implants were developed for patients with good bone stock. Recently it has become clear that these implants have a decreased performance when implanted in bone with low density, such as in osteoporosis. Reduced performance in osteoporotic bone is not unexpected because of the reduced quality of the peri-implant bone and the reduced bone-implant contact area. Neverthele...

The objective of this present study was to create a biosensor which can monitor in situ orthopedic tissue growth juxtaposed to a newly implanted orthopedic material. This biosensor has unique properties including the ability to sense, detect, and control bone regrowth. Such a biosensor is useful to not only regenerate tissue necessary for orthopedic implant success but it also aids in informing...
