This is the thoroughly revised and updated edition of the book which has been written keeping in mind primarily the time constraints of undergraduate medical students who are preparing for their qualifying examination. Timely reference to this book at all professional years (revised CBME curriculum) will help the students to sail smoothly in the viva voce examination under Instruments section. In addition to undergraduates, this book is of immense help to postgraduate students as well, since the basics remain the same. All chapters have been rewritten, including the sections on orthopaedics and anaesthesia. It has 330 instruments and a few operative photographs. Description of suture materials and mesh used for hernia repair has been added, in addition to some important keyboxes.
