THE PROPER EVALUATION OF MUSCULOSKELETAL COMPLAINTS in the United States of America William Min University of Medicine and Dentistry of New Jersey (UMDNJ) Newark New Jersey U.S.A. Introduction Primary care physicians and general orthopaedic physicians examine and diagnose numerous cases of musculoskeletal complaints in the United States annually. The diagnosis of possible oncogenic causes related to the complaint has become an important issue during the delivery of proper health care measures in light of increasing health care costs. The techniques and tools available to the physician for proper diagnosis are evaluated and weighted for their efficacy and appropriateness. Method Proper methods evaluated for efficacy and appropriateness were reviewed from the following sources: Orthopaedic physicians Primary care physicians Orthopaedic journal reviews. Results With the onset of advanced methods in imaging, the initial diagnosis made by history and physical examination is either supported or refuted. These methods, which include the traditional plain radiographs, nuclear magnetic resonance imaging (MRI), computed tomography scans (CT), bone scans, and ultrasound, vary in their effectiveness and costs in determining the possible oncogenic problems that cause musculoskeletal complaints. Also, blood tests are tools that aid in the diagnosis. Referral to an orthopaedic oncologist for a suspected oncogenic pathology aids in further confirmation of the initial diagnosis made by the primary care physician or orthopaedic physician. Conclusion While history and physical examination, imaging methods, and blood tests are tools that the primary care physician and orthopaedic physician have at their disposal, cost considerations must be factored along with the appropriateness and efficacy of the diagnostic tool. The referral to the orthopaedic oncologist remains the most efficacious and cost-efficient method to diagnose the possible oncogenic causes of a musculoskeletal complaint. Literature: 1.
