Heterotopic ossification is a well-recognized complication of musculoskeletal trauma and elective orthopaedic surgery. A series of 10 cases of arthroscopic subacromial decompressions developed postoperative heterotopic bone. In eight, the ectopic bone caused recurrent shoulder impingement. These are the first reported cases in which heterotopic ossification compromised the results of an arthroscopic procedure. It is recommended that the patient at risk (e.g., with active spondolytic arthropathy or a profile of hypertrophic pulmonary osteoarthropathy--obesity, diabetes with a history of chronic pulmonary disease) be considered for heterotopic ossification prophylaxis.

High-resolution ultrasonography (US) has gained increasing popularity as a diagnostic tool for assessment of the soft tissues in shoulder impingement syndrome. US is a powerful and accurate method for diagnosis of rotator cuff tears and other rotator cuff abnormalities, provided the examiner has a detailed knowledge of shoulder anatomy, uses a standardized examination technique, and has a thorough understanding of the potential pitfalls, limitations, and artifacts. False-positive sonographic findings of rotator cuff tears can be caused by the technique (anisotropy, transducer positioning, acoustic shadowing by the deltoid septum), by the anatomy (rotator cuff interval, supraspinatus-infraspinatus interface, musculotendinous junction, fibrocartilaginous insertion), or by disease (criteria for diagnosis of rotator cuff tears, tendon inhomogeneity, acoustic shadowing by scar tissue or calcification, rotator cuff thinning). False-negative sonographic findings of rotator cuff tears can be caused by the technique (transducer frequency, suboptimal focusing, imaging protocol, transducer handling), by the anatomy (nondiastasis of the ruptured tendon fibers, posttraumatic obscuration of landmarks), by disease (tendinosis, calcifications, synovial proliferation, granulation or scar tissue, bursal thickening, massive rotator cuff tears), or by patient factors (obesity, muscularity, limited shoulder motion).
