Book Description
The author of this multimedia work sets himself an ambitious goal: to allow a surgeon to achieve the revision of a prosthesis without too many difficulties (or too much apprehension!) with guaranteed results if he follows the proposed method step by step, and this, even if he is not very experienced in this discipline.To fulfil this purpose, the author provides a clear definition of the press-fit concept (principles and practical applications) and from there, he offers a logical and rigorous method for, first of all, planning the surgery, and then, performing it.The written text is also available as a computerized slide show, coming with a browsing system in order to make a pre-operative planning, which gives real pedagogic value to the whole of this work.

Book Description
Choosing an uncemented femoral prosthesis means first choosing a concept and to be effective, an operator has to have access to all the information that will allow them to reach the desired goals. This is the first step to be made. The quality of a surgical procedure does not depend on the manual skills of the surgeon performing it, but on how he has prepared and performed the operation “virtually” before actually performing it. This is the second step. An operating technique must be adapted to the chosen concept and the purpose of every surgical procedure must be clearly formulated and understood by the operator. This is the third step. Every surgeon has to have a reliable and rigorous radiological method of analysis for evaluating overall results and which suggests ways of improving results.

Book Description
This practical book combines thorough literature review with extensive clinical experience to provide a clear overview of femoral revision arthroplasty, with the aim to present all available surgical techniques and critically discuss pros and cons and evidence-based recommendation for each of them. A wealth of figures and several videos complement the book and guide the reader through the management of potential pitfalls and complications during and after surgery. Particular emphasis is further put on the comparison of different approaches, stem types, and fixation techniques, assisting readers in identifying the best indication. Designed as a practically-oriented tool this book offers an excellent resource for all specialist hip surgeons and fellows wishing to gain insights into this complex and challenging surgical procedure.

Book Description
A strain gage analysis was performed to determine the stresses generated on the lateral surface of two types of porous-coated femoral prostheses. One type of prosthesis was made of wrought titanium (Ti-6Al-4V) alloy with a porous polysulfone coating; the other was a porous-coated alloy meeting the requirements of the ASTM Specification for Cast Cobalt-Chromium-Molybdenum Alloy for Surgical Implant Applications (F 75-82). Various degrees of fit were evaluated, ranging from a loose fit to one in which the stem was cemented into the femoral canal. The results showed that modeling pressfit porous-coated stems using cemented conditions can produce peak stresses on the lateral surface of the stem significantly lower than those for noncemented stems. Based on the fatigue strength of the stem material, the authors show that assessing stem integrity with the assumption that the cemented stem represents a complete bone ingrowth condition may lead to a design evaluation of the femoral stem that is overoptimistic for in vivo fatigue load conditions.

Book Description
This book is published open access under a CC BY 4.0 license. White Paper on Joint Replacement This White Paper details the status of hip and knee arthroplasty care in Germany. Hip and knee replacements are amongst the most frequently performed procedures and usually become necessarily due to age-related wear of the joint, osteoarthritis and fractures of the femoral neck. In light of demographic change, demands with regard to standards of care and the procedures are likely to rise. Contents • This White Paper contains information on indications, procedures, health economic aspects and the healthcare system stakeholders involved. • It portrays current developments with regard to the prevalence of hip and knee arthroplasty, the healthcare situation and quality of care within the chain of medical care. • This book is complemented by a chapter assessing the current situation from an expert perspective with contributions from renowned experts in the fields of science, medical technology and medical practice. This book addresses people involved in shaping and representing the healthcare system from a variety of fields including medical professions, health insurances and health sciences as well as journalists and patient representatives.
