Preview Campbell's Operative Orthopaedics, 11th Edition

In Memory of Rocco A. Calandruccio Peter G. Carnesale Marcus J. Stewart 1923–2007 1937–2006 1911–2007 Since the last edition of this text, we have been saddened by the loss of three of our colleagues, friends, and mentors. Each of these outstanding orthopaedic surgeons was a leader, innovator, teacher, and role model, and we have valued their wisdom and experience, which they so generously shared with us personally and with so many others through their contributions to several editions of Campbell’s Operative Orthopaedics. We all will miss their advice and counsel and their dedication to our profession.

In an average healthy adult younger than 50 years of age, we prefer to leave the tourniquet infl ated for no more than 2 hours. If an opera- tion on the lower extremity takes longer than 2 hours, it is better to finish it as rapidly as possible than to defl ate the tourniquet for 10 minutes and then reinfl ate it. It has been found that 40 minutes is required for the tissues to return to normal after prolonged use of a tourniquet. Consequently, the previous practice of defl ating the tour- niquet for 10 minutes seems to be inadequate. Post- tourniquet syndrome, as fi rst recognized by Bunnell, is a A common reaction to prolonged ischemia and is character- ized by edema, pallor, joint stiffness, motor weakness, and subjective numbness. This complication is thought to be related to the duration of ischemia and not to the mechani- cal effect of the tourniquet. Sapega et al. have documented interstitial edema, increased capillary permeability, micro- vascular congestion, and decreased muscle contractility after 2 to 3 hours of ischemia. Post-tourniquet syndrome interferes with early motion and results in increased nar- cotic requirements. Spontaneous resolution usually occurs within 1 week. Compartment syndrome, rhabdomyolysis, and pulmo- nary emboli are rare complications of tourniquet use.
