international orthopedic surgeons who specialize in surgery of the shoulder and elbow. Focus topics of this society include elbow instability, glenohumeral instability, basic science, rotator cuff, arthroscopy, elbow/osseous reconstruction, arthroplasty (primary, long-term results, complications, and revisions), and general issues of the shoulder and elbow. Arthritis and its effect on both young and older patients is an emerging topic. 4. The American Society for Surgery of the Hand (ASSH) (http://www.assh.org): the ASSH was founded in 1946. This society boasts of being the oldest medical specialty society in the United States devoted entirely to CME related to hand surgery. Musculoskeletal and congenital conditions and injuries to bones of the hand and wrist complex are studied. Wrist ligament, wrist arthritis/phalanx fractures, and distal radius are important topics of interest as well. Numerous other areas of interest are found on their web site. 5. The Arthroscopy Association of North America (AANA) (http://www.aana.org): the AANA exists to “promote, encourage, support and foster . . . the development and dissemination of knowledge . . . of arthroscopic surgery to improve upon the diagnosis and treatment of diseases and injuries of the musculoskeletal system.”13 Rotator cuff and subacromial space pathology; miscellaneous shoulder conditions, complications and controversies in shoulder arthroscopy, articular cartilage knee surgery, meniscus surgery, anterior cruciate ligament update, and posterior cruciate ligament and patellofemoral joint are just a few orthopedic areas of interest this subspecialty studies. Safety and efficacy of thermal surgery of the shoulder, radiofrequency chondroplasty, meniscal repair using the inside-out suture technique, and using patellar tendon or hamstring grafts for anterior cruciate ligament reconstruction are newer topics and recent advances in orthopedic arthroscopy techniques. 6. The Federation of Spine Associations (FSA) consists of the following 4 societies with recommended links: American Spinal Injury Association (ASIA) (http:// www.asia-spinalinjury.org/), Cervical Spine Research Society (CSRS) (http://www.csrs.org/), North American Spine Society (NASS) (http://www.spine.org/), and Scoliosis Research Society (SRS) (http://srs.org/). This federation focuses on spine-related disorders including scoliosis, pediatric congenital disorders, adult spine degeneration, and other spine disorders including fractures and spinal cord injuries among numerous other spine-related disorders. 7. The American Association of Hip and Knee Surgeons (AAHKS) (http://www.aahks.org) was established in 1991. The mission of the AAHKS is to provide leadership in advocacy, education, and research to achieve excellence in hip and knee patient care. Topics such as implant design, results, surgical techniques, and complications of primary and revision total joint arthoplasty L.M.B. Gehrig Orthopedic surgery 367 (TJA) are a few areas of interest. With the population living longer, and arthritis a very common musculoskeletal condition, TJA (replacement) will continue to be a common orthopedic procedure. 8. The Hip Society (http://www.hipsoc.org) and Knee Society (http://www.kneesociety.org) are 2 other societies within orthopedic surgery whose interests are joints and topics and controversies surrounding total joint replacements, reconstruction, and newer technologies involving mini-incisions and robotics. Hip Society Awards include the Otto Aufranc Award, the John Charnley Award, and the Frank Stinchfield Award. The Knee Society Awards within the society include the Mark Coventry, Chitranjan Ranawat, and John Insall. Further information regarding these joint societies may be found on their web site. 9. The Limb Lengthening and Reconstruction Society: ASAMI–North America (http://www.llrs.org). Founded as ASAMI–North America (the Association for the Study and Application of Methods of Ilizarov), the Limb Lengthening and Reconstruction Society is devoted to clinical excellence in such areas as in limb lengthening, limb reconstruction, extremity deformity correction, reconstruction of failed fractures, and trauma. 10. The Musculoskeletal Tumor Society (MSTS) (http:// www.msts.org) aims to advance the science of orthopedic oncology and to promote high standards of patient care in those with bone and soft tissue tumors. Current principles in orthopedic oncology as well as newer modalities for the treatment of bone and softtissue tumors are major focuses. 11. The Orthopedic Rehabilitation Association (ORA) (http://www.orthorehabassoc.org). These surgeons are interested in the orthopedic care of patients with complex musculoskeletal problems, which are global in nature and not necessarily being addressed by other specialty societies. Areas of interest include but are not limited to the following: interdisciplinary care; stroke, traumatic brain injury, cerebral palsy, and multiple sclerosis; spinal cord injury; various neuromuscular disorders; amputations; sports medicine; lower-extremity problems of the diabetic patient; care after tumor surgery; orthotics and prosthetics and robotics; and innovative scientific and engineering developments in rehabilitation.
