The principles and techniques used to reduce or eliminate blood transfusions can be applied to the standard practice of orthopaedic surgery. The overall goal is to enable orthopaedic surgeons who are interested in reducing allogeneic transfusions to find a method that fits their practice.

Unstable pelvic ring injuries in hemodynamically unstable patients are life-threatening emergencies that many orthopaedic surgeons encounter in practice. Therefore, it is important to be up to date regarding current methods of evaluating, assessing, and treating patients with these complex and severe injuries. Surgeons should first determine whether patients have hemodynamic instability and identify the source of the hemorrhage. Patients should then be assessed for stabilization of unstable pelvic ring injuries.

The symptoms associated with lumbar spinal stenosis can decrease quality of life and may cause patients to seek treatment. Except in rare cases of rapid neurologic progression or cauda equina syndrome, nonsurgical modalities should be the initial treatment choice. Activity modification, a variety of medications, epidural steroid injections, and other methods are recommended for pain reduction. ⋯ Arthrodesis, either with or without instrumentation, is also indicated in some patients. Several studies report that surgical treatment produces better outcomes than nonsurgical treatment in the short term; however, the results tend to deteriorate with time. Lumbar decompressive surgery can be complicated by epidural hematoma, deep venous thrombosis, dural tear, infection, nerve root injury, and recurrence of symptoms.

Review Comparative Study
Different surgical options for monocompartmental osteoarthritis of the knee: high tibial osteotomy versus unicompartmental knee arthroplasty versus total knee arthroplasty: indications, techniques, results, and controversies.
The decision of what procedure to perform for the treatment of monocompartmental osteoarthritis of the knee when nonsurgical treatment methods fail remains controversial. Recent advances using osteotomy, unicompartmental knee replacement, and total knee replacement have been reported. ⋯ Many techniques now involve osteotomies below the tibial tubercle. Unicompartmental knee replacement can be done using a standard approach, but less invasive approaches exist, along with minimally invasive approaches for total knee replacement, rather than the standard large incision, that promote decreased soft-tissue destruction.

Cervical spine injuries are frequently encountered in any practice treating patients in the emergency department or outpatient trauma victims. When upper or lower cervical spine injuries are suspected, immediate immobilization, physical and neurologic examination, and radiographic evaluation are imperative. For spinal cord injuries, knowledge of microscopic and cellular pathology helps to determine appropriate management.
