Re:vision

This unique text utilizes a bulleted, case-based approach to present a variety of surgical strategies and techniques for tackling the many challenges posed by revision foot and ankle surgery.The book is organized thematically into sections on the forefoot, trauma, sports injuries, and arthritis and reconstruction, with each chapter including key takeaway points, discussions of evaluation, surgical planning, and the cases themselves. Specific revision topics presented include first MTP joint fusion, failed bunion and hammertoe, failed Lisfranc and fifth metatarsal fracture, failed flatfoot and subtalar fusion, and nonunion of ankle fusion and failed total ankle replacement, among others.

This book aims to lay bare the logical foundations of tractable reasoning. It draws on Marvin Minsky's seminal work on frames, which has been highly influential in computer science and, to a lesser extent, in cognitive science. Only very few people have explored ideas about frames in logic, which is why the investigation in this book breaks new ground. The apparent intractability of dynamic, inferential reasoning is an unsolved problem in both cognitive science and logic-oriented artificial intelligence.
