FIGURE 9.19. Patient setup before draping. Note the position of the C-arm. The Mayo stand sits above the patient's shoulder for organization of instruments and easy access to operative field.

ible patients, start with 25 to 50 lb force, and with large stiff patients, use 50 to 75 lb.

Using the C-arm fluoroscope, start with the anterolateral portal (Figure 9.20), observing the 14-gauge 5.25-inch intracath pass between the head of the fe mur and acetabulum, closer to the femur to avoid puncturing the labrum. Listen for a hiss as the joint suction seal is broken and observe the traction forces reduce on the tensiometer readout (Figure 9.21). Obtain the desired distraction (usually greater than 1.2

FIGURE 9.20. (A) Patient in a lateral decubitus position with the right hip marked. Note the trochanter and the anterosuperior iliac spine with the portals marked out. A, anterior; AI, anteroinferior; AL, anterolateral; ASIS, anterosuperior iliac spine; PL, posterolateral. (B) Right hip with the arthroscope in the anterolateral portal; the needle is in the posterolateral portal and the anterior portal. (C) Accessory portals include the anteroinferior lateral and anteroinferior medial portal in addition to the anterolateral and posterolateral portals. The arthroscope is in the anteroinferior lateral and the shaver is in the anteroinferior medial portal.

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.
