Patient-specific Instruments for Total Knee Arthroplasty
Paul F. Lachiewicz J Am Acad Orthop Surg September 2013 vol. 21 no. 9 Abstract The use of patient-specific instruments for total knee arthroplasty shifts computer navigation for bone landmark registration and implant positioning from the intraoperative to the preoperative setting. Each system requires preoperative MRI or CT, with specifications determined by the instrument manufacturer. […]
Comprehensive Approach to the Evaluation of Groin Pain
Juan C. Suarez J Am Acad Orthop SurgSeptember 2013vol. 21 no. 9 Abstract Groin pain is often related to hip pathology. As a result, groin pain is a clinical complaint encountered by orthopaedic surgeons. Approximately one in four persons will develop symptomatic hip arthritis before age 85 years. Groin injuries account for approximately 1 in […]
Choosing Fusion Levels in Adolescent Idiopathic Scoliosis
Per David Trobisch J Am Acad Orthop SurgSeptember 2013vol. 21 no. 9 Abstract Correct identification of fusion levels in surgical planning for the management of adolescent idiopathic scoliosis is a complex task. Several classification systems and algorithms exist to assist surgeons in determining the appropriate levels to be instrumented. The Lenke classification is the benchmark […]
Management of Shoulder Instability in the Skeletally Immature Patient
Xinning Li J Am Acad Orthop SurgSeptember 2013vol. 21 no. 9 Abstract Several studies have focused on management of shoulder instability in the adolescent and young adult population. However, a paucity of literature exists regarding shoulder dislocation in the skeletally immature population. The presence of an open physis makes the dislocated pediatric shoulder a challenging […]
Proximal Humerus and Humeral Shaft Nonunions
Edwin R. Cadet J Am Acad Orthop SurgSeptember 2013vol. 21 no. 9 Abstract The rate of nonunion is estimated to be 1.1% to 10% following closed treatment of proximal humerus fracture and 5.5% following closed treatment of humeral shaft fracture. Surgical management should be considered for fractures that demonstrate no evidence of progressive healing on […]
Treatment of Distal Radius Fractures
Jayson Murray J Am Acad Orthop Surg. Vol 21 Nº 8 August 2013 The American Academy of Orthopaedic Surgeons has developed Appropriate Use Criteria (AUC) for treating distal radius fractures (DRF). Evidence-based information, in conjunction with the clinical expertise of physicians, was used to develop the criteria to improve patient care and obtain best outcomes […]
Cysts About the Knee: Evaluation and Management
Drew Stein J Am Acad Orthop Surg. Vol 21 Nº 8 August 2013 Popliteal (Baker) cysts, meniscal cysts, proximal tibiofibular joint cysts, and cruciate ligament ganglion cysts are cystic masses commonly found about the knee. Popliteal cysts form when a bursa swells with synovial fluid, with or without a clear inciting etiology. Presentation ranges from […]
Sarcoma Chemotherapy
Brian E. Walczak J Am Acad Orthop Surg. Vol 21 Nº 8 August 2013 Sarcomas are a rare, heterogeneous group of malignant tumors of the bone or soft tissue. Although historically intended for the pharmaceutical treatment of microbes, today chemotherapy is used in orthopaedic oncology and is arguably the primary reason for improved survivorship. Agents […]
Pelvic Fractures: Part 1. Evaluation, Classification, and Resuscitation
Joshua R. Langford, J Am Acad Orthop Surg. Vol 21 Nº 8 August 2013 Pelvic fractures range in severity from low-energy, generally benign lateral compression injuries to life-threatening, unstable fracture patterns. Initial management of severe pelvic fractures should follow Advanced Trauma Life Support protocols. Initial reduction of pelvic blood loss can be provided by binders, […]
Pelvic Fractures: Part 2. Contemporary Indications and Techniques for Definitive Surgical Management
Joshua R. Langford, J Am Acad Orthop Surg. Vol 21 Nº 8 August 2013 Once the patient with pelvic fracture is resuscitated and stabilized, definitive surgical management and anatomic restoration of the pelvic ring become the goal. Understanding injury pattern by stress examination with the patient under anesthesia helps elucidate the instability. Early fixation of […]
