Introduction: Recently the most accurate diagnostic method in the diagnosis of prosthesis infection is the combination of Tc-99m labeled leukocyte/bone marrow imaging. However the diagnostic efficiency of the test is influenced because of its low spatial resolution. Recently SPECT/CT imaging is implicated in this test with efficient additional diagnostic improvement. In the dep...
BACKGROUND Compliant, self-adjusting compression technology is a novel approach for durable prosthetic fixation of the knee. However, the long-term survival of these constructs is unknown. QUESTIONS/PURPOSES We therefore determined the survival of the Compress prosthesis (Biomet Inc, Warsaw, IN, USA) at 5 and 10 actuarial years and identified the failure modes for this form of prosthetic fixa...
HYPOTHESIS Factors that lead to failures in antireflux procedures can be identified, and dealing with them at the initial operation may decrease the number of such failures. DESIGN Analysis of symptoms, 24-hour esophageal pH monitoring, manometry, upper gastrointestinal tract radiographs, and correlation with operative anatomic findings. SETTING University referral center. PATIENTS Forty-...
The retrospective study was conducted to assess the dental implants that experienced failure. It was conducted at the dental clinic of the Aga Khan University Hospital, Karachi, and comprised record of dental implants from July 2010 to June 2015. Variables such as patient age, gender and systemic status, length and diameter of implants, bone grafting, type of definitive prosthesis (crown or bri...
Seven cases of massive thrombosis of an aortic Bjork-Shiley prosthesis were encountered among 433 valvular implants. Four patients died before treatment could be instituted, and three underwent repeat surgery successfully. Anticoagulation therapy was probably well maintained in four, and poorly maintained in three patients. These cases illustrated the need for a high index of suspicion and prom...

A computer-based model is used to investigate the total cost of primary total hip-joint replacement. The model takes into account the probability of prosthesis failure, death and re-revision. The results emphasize the importance of age at insertion, demonstrating that the expected life-span of the patient has a major influence on the total cost for a given prosthesis. The discussion considers t...
Early and late infection as well as loosening and mechanical failure are among the postoperative complications most often reported following reconstruction with a tumour prosthesis in patients with a sarcoma around the knee. Scarce instances of periprosthetic fractures have been reported. The literature includes the description of two patients with such a complication, however no treatment reco...
INTRODUCTION Bacillus Cereus endocarditis is a rare condition which has been implicated in intravenous drug users, and in patients with prosthetic heart valves. We report a rare case of Bacillus Cereus infecting a permanent pacing wire. CASE PRESENTATION A 69 year old female with a permanent pacemaker presented with rigors, sweats and weight loss. Blood cultures grew Bacillus Cereus; Transeso...
We describe the application of a non-invasive extendible endoprosthetic replacement in skeletally-mature patients undergoing revision for failed joint replacement with resultant limb-length inequality after malignant or non-malignant disease. This prosthesis was developed for tumour surgery in skeletally-immature patients but has now been adapted for use in revision procedures to reconstruct th...
