excised (Figure 10.30D-F). The postoperative radiograph demonstrates removal of the intraarticular fragments with a concentric reduction, while the inferior femoral head fracture remains nondisplaced (Figure 10.30G).

Labral Tears

Traumatic labral tears may respond remarkably well to arthroscopic debridement.12-16 However, at arthroscopy, be especially cognizant of any underlying

procedure be completed in a timely and efficient fashion. It is appropriate to abandon the procedure if inappropriate fluid extravasation is encountered or if the procedure cannot be completed within a reasonable amount of time.

Case 1

A 16-year-old obese girl sustained a posterior dislocation of her right hip (Figure 10.30A). A closed reduction was performed. Postreduction radiography demonstrated a nonconcentric reduction as well as a nondisplaced Pipkin I inferior femoral head fracture (Figure 10.30B). A CT scan demonstrated at least two entrapped intraarticular fragments (Figure 10.30C). Arthroscopy revealed numerous fragments, which were

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.
