US can depict most partial-thickness tears with use of the criteria described.

Marrow edema cannot be reliably distinguished from osteomyelitis with MR imaging. Gadopentetate dimeglumine is of limited use. Some previously published false-positive reports of osteomyelitis were most likely due to edema of the marrow. MR imaging is useful in planning surgery of the infected diabetic foot, as it enables reliable distinction between normal and abnormal areas.

Placement of ventriculo-peritoneal (VP) shunts is an established procedure for treatment of hydrocephalus. With increasing longevity following successful treatment, complications are becoming more common. The authors reviewed 350 VP shunts in 242 patients and found five uncommon complications relating to the peritoneal end of the catheter: (a) cerebrospinal fluid (CSF) pseudocyst of the lesser sac, (b) subphrenic CSF loculation, (c) bowel perforation and formation of a CSF-enteric fistula, (d) intrathoracic migration of the tip of the shunt, and (e) intractable CSF ascites.

Although an associationbetweenirregulargreatertuberositiesand rotator cuff tearshasbeensuggested,no formal studieshavebeendone. This study was designedto in vestigate the relationship between greater tuberosity irregularities, rotator cuff tears, and age. SUBJECTS AND METHODS. Sonographicexaminationsof both shouldersof 77 asymptomatic individuals (154 shoulders) between 30 and 80 years old were performed. The rotatorcuffs and greatertuberositieswere evaluated.Full-and partial-thicknessrotatorcuff tears were given equal significance. A two-tailed Fisher's exact test, a Student's t test, and lo
