Case Reports
Concomitant sacroiliac joint pain in patients with lumbar disc herniation: case series.
Recent studies have shown that not all lumbar disc herniations are symptomatic and that when followed longitudinally, these patients develop back pain independent of the previous imaging study. This is a case report of two patients with radicular symptoms and lumbar disc herniations that underwent diagnostic injections to locate their pain generator. Both patients failed to respond to transforaminal epidural steroid injections. ⋯ They were both treated conservatively for sacroiliac joint pain and did well. One remained pain free after several months and the second remained with minimal pain until she presented again in her 3rd month of pregnancy with return of her pain. The differential diagnosis of lumbar radicular pain is discussed as well as the authors' experience in using diagnostic injections.

Four patients with acromioclavicular joint injuries (one type II, two type III, one type V), two patients without acromioclavicular joint injury, and a fresh-frozen cadaver underwent magnetic resonance imaging (MRI) and plain radiographs. The normal conoid and trapezoid ligaments were easily identified in the cadaver and the two uninjured patients. ⋯ Thus, the grade of injury, as determined by the change in the coracoclavicular interval onplain radiography and defined by the Rockwood classification system, failed to correlate with the pathoanatomy seen on MRI in two of the four injured patients. These findings suggest that improvements in the classification of these injuries may be necessary.
