I agree with you about grammitical typoes. There are some in the book. But I would have to disagree with you in terms of mistakes. Dr Scot Malay, the editor of the PI Manual and attending at Penn Presbyterian Medical Center (Philadelphia, PA), is an expert in foot and ankle medicine and surgery. To make such a claim that the PI Manual is full of errors implies that Dr. Malay is incompetent. I have heard and read many excellent impressive things about Dr. Malay and his two huge career achievements: 1) The PI Manual book and 2) his article about the Malay Classification system for toenail trauma (now a classical paper).
POCKET PODIATRICS?! That book has more grammtical errors than the PI Manual (no offense to Dr Watkins, the editor of POCKET PODIATRICS). I feel that Dr. Malay was a better editor than Dr Watkins. I would rely on the grammatical accuracy of the PI Manual book over POCKET PODIATRICS. Presby and Hershey Manuals are getting outdated. The only modern book on podiatry that is useful is the PI Manual, 2nd edition. It is the authoritative book for the APMLE exams, board certification exams, for pimping sessions in 3rd and 4th year podiatry school, and for postgraduate training and fellowship. Congrats to Dr. Malay! I cannot wait for the 3rd edition to come out!
What is true though: to study for Part 2 and Part 3 APMLE board exams, the PI Manual, POCKET PODIATRICS, FOOT AND ANKLE SECRETS, and the PEARLS book are the 4 best books to read to prepare for these two exams. Get these 4 books, read them thoroughly, and you will pass part 2 and part 3 APMLE boards. Presby manual, Hershey Manual, McGlamery textbook, CROZER manual, and INOVA manual are not necessary/overkill.
