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.

Adolescent idiopathic scoliosis is a three-dimensional deformity of the spine. Despite active efforts by different research teams, the etiology of scoliosis remains unclear. Treatment of scoliosis requires a solid understanding of the natural history of the disorder as well as sound clinical judgment. ⋯ Bracing is the only nonsurgical measure proven to have any effect on halting the progression of scoliosis. Other forms of conservative treatment have not been shown to significantly modify the natural history of idiopathic scoliosis. Bracing results are directly related to compliance with brace treatment; therefore, optimal results cannot be achieved without the patient's cooperation and family support.

The Lenke and associates classification system of adolescent idiopathic scoliosis (AIS) was developed to provide a comprehensive and reliable means to categorize all surgical AIS curves. This classification system requires analysis of the upright coronal and sagittal radiographs along with the supine side bending radiographic views. The triad classification system consists of a curve type (1-6), a lumbar spine modifier (A, B, C), and a sagittal thoracic modifier (-, N, +). ⋯ The recommendations are that the major and structural minor curves are included in the instrumentation and fusion and the nonstructural minor curves are excluded. Overall, the classification system is treatment directed; however, there are other aspects of the radiographic and clinical deformity that may suggest deviation from the recommendations of the classification system. The ultimate goal of this classification system is to allow organization of similar curve patterns to provide comparisons of various treatment methods to provide optimal treatment for each AIS surgical patient.

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.
