bone graft based on the 1,2 intercompartmental supraretinacular artery (1,2 ICSRA) pedicle with K-wire fixation was selected for this patient (Fig. 58-7).

The surgery can be performed under general or axillary block anesthesia, and general anesthesia was used. The patient was placed in the supine position, a brachial tourniquet was placed, and perioperative intravenous first-generation cephalosporin was administered. The right upper extremity was exsanguinated by elevation rather than by using an esmarch, so the vascular pedicle could be more readily identified. A curvilinear "lazy S-shaped" incision was made, with the distal limb aligned with the palmar aspect of the first dorsal compartment, the oblique transverse midportion aligned with the radioscaphoid joint, and the proximal limb aligned with the second dorsal compartment.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
