Contrast reaction from hip arthrogram.

Arthrography is considered a safe procedure with rare reactions to intra-articular contrast administration. Although the use of intra-articular contrast carries a small risk of reaction, no prior serious complications had been encountered in our experience with arthrography. We report a patient's prolonged reaction to contrast media after an arthrogram of the hip. Literature review demonstrated no prior report of contrast media reactions to hip arthrography. Therefore, we decided to review the literature and report our case.

Transoral vertebral augmentation with polymethylmethacrylate in the treatment of a patient with a dens fracture nonunion and subarticular vertebral body fracture of C2.

The injection of polymethylmethacrylate (PMMA) is a minimally invasive, image-guided procedure used to treat vertebral fractures due to osteoporosis, metastatic lesions, multiple myeloma, and benign but destabilizing bone tumors. The injection of PMMA into the C2 vertebral body using the transoral technique has been reported in three separate patients for treatment of benign tumors (a vertebral hemangioma and an aneurysmal bone cyst) and for multiple myeloma in the third patient. Although the injection of PMMA into the vertebral body is most commonly performed to treat benign vertebral compression fractures, a transoral C2 approach has not been reported in the English literature as a treatment for a benign fracture of C2. We report the treatment of a fracture and nonunion of the base of the dens and a subarticular fracture of the vertebral body of C2 using a bilateral transoral approach.

Technical strategies and anatomic considerations for parapedicular access to thoracic and lumbar vertebral bodies.

OBJECTIVES: To investigate and illustrate a variation on the traditional percutaneous access to the vertebral body via a parapedicular approach. DESIGN: An effective parapedicular access technique that could safely and reliably guide the needle tip into the center of the vertebral body was developed from cadaver dissection observations for the purpose of clinical use. PATIENTS: A total of 102 vertebral compression fractures from T-4 to L-5 were treated via the parapedicular access at our institution between July 2005 and March 2006. There were 72 patients between the ages of 17 and 96 years (mean age: 68.2 years) who underwent treatment. RESULTS: The cadaver dissection revealed a relatively avascular and aneural portion of the vertebral body along the superior margin of the vertebral body-pedicle junction. A total 102 vertebral fractures were treated using the parapedicular access technique without any recognized clinical complications from the needle access or the instrumentation. CONCLUSIONS: The thoracic and lumbar vertebral bodies may be safely, reliably, and reproducibly accessed using a percutaneous parapedicular access technique. The technique presented represents a relatively avascular and aneural approach to vertebral body.

Magnetic resonance imaging of the rotator cuff interval.

The rotator cuff interval (RCI) is an important and anatomically complex region of the rotator cuff that is critically important to normal glenohumeral function. Recognition of common pathologies in this region on imaging examinations is especially important as injuries may be difficult to detect on clinical examination and even at arthroscopy. Familiarity with the magnetic resonance imaging appearance of the normal and abnormal RCI and the ability to convey findings to orthopedic and sports medicine referrers are essential to facilitate prompt creation of effective treatment plans.
