PURPOSE To examine the frequency of technical errors during implantation of the Austin Moore prosthesis in a public hospital. METHODS Radiographs and charts of 147 consecutive uncemented Austin Moore hemiarthoplasty patients were retrospectively reviewed with particular reference to intra-operative errors associated with early failure of the prosthesis. RESULTS 48% of the patients had at le...

The objective of this study was to make an overview that can be useful in determining which type and brand of prosthesis a patient has when visiting the emergency department or outpatient clinic with a periprosthetic fracture, dislocation, or implant failure. The commonly used prostheses in Europe are opted for this list. The radiographs used for this list are obtained either from the company o...

BACKGROUND Among various types of composite biological reconstruction, pasteurized autograft-prosthesis composite (PPC) is popular when allograft is unavailable. Previous limited cohort study indicated result comparable to tumor prosthesis. However, as case number and follow-up increase, we experienced more complications than anticipated. We questioned the usefulness of PPC as a viable reconstr...

There are many conditions that may be responsible of a painful knee prosthesis. The possible causes are not always easily diagnosed. Common causes of prosthetic failure, such as aseptic loosening, infection, instability, progressive patellar arthropathy and recurrent synovitis are associated with clearly defined radiographic and/or clinical evidence. Prosthetic infection should always be consid...

Voice prosthesis-assisted speech rehabilitation after total laryngectomy has proven to be successful in the majority of patients and exceeds the results of traditional oesophageal speech. Nevertheless 10-30% failure rates are still reported. In part this is due to prosthesis-related problems, in particular ingrowth of Candida species in the valve-bearing parts of the devices. A new indwelling, ...

Background: Conductive hearing loss due to ossicular abnormalities occurs from many causes, including trauma, infection, cholesteatoma, surgery and congenital anomalies. Surgical reconstruction of the ossicular chain is a wellestablished procedure for repair of ossicular defects, but is still plagued by high failure rates. Underlying disease and proper sizing of prostheses are two challenges th...

INTRODUCTION Every patient needs a comprehensive treatment planning. Dentists must consider the advantages and disadvantages of the available implant prosthetic options and match them to patient's expectations. Hybrid denture prosthesis is one, i.e., fabricated and retained by screw threaded into implant abutments, most of the time on four implants. Sometimes due to failure of an implant, the p...

Extra-oral prosthesis improves the appearance and enhances confidence of the patient. Large facial defects involving lower half of the face are very difficult to treat prosthetically because of the mobility of the soft tissue margins, opening and closing movement of the mandible and poor retentive features of the defect. This article features a cancer survivor for whom a facial prosthesis was f...

Painful hip prosthesis is the most feared immediate and remote complication of a primary implant and usually represents the failure of one or more therapeutic moments. In cases of aseptic implant failure, the causes invoked may be represented by an incorrect indication, the quality of materials, local and general condition of the patient and especially from a bad joint biomechanics. In cases of...
