introduction: rheumatic heart disease still remains one of the leading causes of congestive heart failure and death owing to valvular pathologies, in developing countries. valve replacement still remains the treatment of choice in such patients.the aim of this study wasto analyze the postoperative outcome of  double valve replacement (mitral and aortic ) in patients of rheumatic heart disease. ...

Modular neck hip prosthesis born in the 1990 with the aim of allowing the surgeon to modify CCD angle, offset and femoral anteversion intra-operatively restoring patient's original biomechanics. In order to achieve the best biomechanics of the reconstructed hip, preoperative planning is essential. In the last few years modularity has been questioned and an argument made for the return to mono b...

INTRODUCTION Isolated patellofemoral osteoarthritis can be treated with patellofemoral arthroplasty. CASE PRESENTATION We present two cases of isolated patellofemoral osteoarthritis treated with Low Contact Stress patellofemoral arthroplasty; in both cases the polyethylene mobile-bearing of the patellar component dissociated from the metal backing. One patient had a revision to a Richards pat...

Unlike natural teeth, osseointegrated implants react bio mecha­ nically in a different fashion to occlusal load due to lack of the periodontal ligament. Hence, the dental implants may be more prone to occlusal overloading, which is often regarded as one of the potential causes for peri­implant bone loss and failure of the implant/implant prosthesis. Stability of the intercuspal position and red...

It is also important to determine if the malleus is mobile by massaging the tympanic membrane under a Siebel otoscope and microscope. If the malleus is mobile, a normal stapedectomy can be performed, consisting of an incus to oval window prosthesis. This operation has a high rate of success (95%). If the malleus is fixed, however, it is necessary to create a malleus to oval window prosthesis. B...

INTRODUCTION In laryngectomised patients, tracheoesophageal speech is the gold standard for voice rehabilitation. This study evaluated complications related to the tracheoesophageal puncture (TEP) and the success rate in voice prosthesis after total laryngectomy at our institution over a 10-year period. MATERIALS AND METHODS A retrospective review of 22 TEPs was performed between January 1998...

When aseptic failure of the bond between the cement and the prosthesis of a total joint replacement occurs, complete removal of the cement has been advocated before the insertion of a new prosthesis. The present study questions this practice. Both laboratory tests on variously prepared specimens of cement and clinical experiences demonstrate that recementing over old cement is a practical alter...
