One of the primary goals in the perioperative care of orthopaedic patients undergoing surgery is the avoidance of allogeneic transfusion. There are a number of ways to lessen blood loss during surgical intervention including regional hypotensive anesthesia, careful and atraumatic surgical technique, and coagulation of bleeding surfaces. ⋯ The use of perioperative recombinant erythropoietin is also a useful adjunct to promote stimulation of the bone marrow and increased red cell production. Although many infectious diseases that are transmitted through allogeneic blood transfusions have been lessened by better screening techniques, there is still potential life threatening reactions and viral transmissions that may be avoided by comprehensive blood management in joint arthroplasty.

Abnormal posttraumatic pain may delay recovery and severely impact health-related quality of life. The term complex regional pain syndrome describes abnormally intense and prolonged pain that is not related to tissue damage and is sometimes a sequela of injury. Various treatment strategies, including therapy, parental interventions, and peripheral surgery, are used to manage the condition.

Posterior pelvic ring injuries disrupt the weight-bearing function of the pelvis and cause deformity that results in pain and loss of function. The indications for reduction and fixation are the presence of instability and/or deformity. ⋯ Although techniques exist for both open and closed reductions, the main dfficulty remains achieving anatomic restoration of the pelvis. Whether posterior pelvic ring injuries are best treated using closed reduction and fixation or open reduction and fixation remains a controversial topic.

In some groups of polytrauma patients, particularly those with chest injuries, head injuries, and those with mangled extremities, early total care of major bone fractures may be potentially harmful. Delaying all orthopaedic surgery, however, is also not always the best approach. In these situations, damage control orthopaedics, which emphasizes the stabilization and control of the injury rather than repair will add little additional physiologic insult to the patient and is a treatment option that should be considered.

The increasing number of hip fractures in the elderly constitutes a health care burden. The subset of unstable intertrochanteric hip fractures is important because the treatment of these fractures continues to be hampered by a moderate complication rate. Osteoporosis, fracture geometry, and the success of surgical treatment are strong predictors of outcome. The surgeon is in control of fracture reduction, implant selection, and implant placement, all of which must be optimized to ensure the success of surgical intervention.
