Localizing the acromioclavicular joint can be difficult. Using bony landmarks--the clavicle and the spine of the scapula--the acromioclavicular joint can be consistently localized for physical examination, injections, and surgery.

The results for young patients in three diagnostic groups--osteoarthritis, posttraumatic arthritis, and osteonecrosis--show clearly that the uncemented procedure requires longer a recovery time than the cemented procedure. A more aggressive physical therapy program has resulted in an earlier return to function, as shown in these graphs. In conclusion, our experience with this operative procedure includes excellent patient acceptance, a failure rate comparable to that in Europe, a longer period of recovery than that for cemented arthroplasty, excellent results in revision of failed cemented arthroplasty, and an encouraging facility in the difficult case.
A single case of back pain due to Blastomyces dermatitidis infection limited solely to the skeleton is reported with a discussion of the differential diagnosis. This rare disease must be differentiated from other destructive bone lesions such as tuberculosis or tumors because of the availability of effective treatment.

The lateral X-ray view of the knee is more likely to yield the diagnosis of osteochondritis dissecans of the femoral condyles if the examiner is aware that most cases are located in the subarticular bone of the medial femoral condyle between two lines: The first extended anteriorly from the density of the roof of the intercondylar notch, and the second, extended distally from the posterior cortex of the distal femoral diaphysis.
