This fully revised and updated follow-up to Dr. William B. Geissler’s Wrist Arthroscopy has expanded its scope to include arthroscopy techniques of the elbow in addition to the wrist. This practical guide covers fundamental topics, such as arthroscopic anatomy and the proper evaluation of wrist and elbow pain, along with advanced discussions of electrothermal shrinkage, arthroscopy of the thumb and small joints of the hand, and specific diagnoses for an array of common injuries. Current minimally invasive procedures are described in detail, including management of carpal instability, arthroscopic proximal row carpectomy, arthroscopic knotless TFCC repair, arthroscopic SLIC screw for scapholunate instability, and arthroscopic fixation intra-articular fractures of the hand. Tips and tricks are highlighted that make implementing new techniques easier.
