Anatomic and structural evaluation of the hip: a cross-sectional imaging technique combining anatomic and biomechanical evaluations.

To describe a technique of cross-sectional imaging of the adult hip designed to evaluate for anatomic anomalies that may predispose to internal derangement in addition to the routine anatomic assessment. Magnetic resonance (MR) imaging, MR arthrography, and multidetector computed tomography (MDCT) scanning protocols utilize high-resolution imaging, and the surrounding anatomy is also assessed using these scanning techniques. Various measurements may be obtained to assess the overarching anatomic configuration including the caput caput collum diaphysis angle, the femoral angle of torsion, the acetabular angle of torsion, the center edge angle, and the femur length.

Nomenclature and standard reporting terminology of intervertebral disk herniation.

Spine pathology is ubiquitous and is encountered by nearly all medical specialties. The anatomy of the spine is complex, but the language used to describe pathology may be even more complex. Many of the common references differ in their nomenclature used to report intervertebral disk herniation. This article summarizes and relates the standard recommendations for reporting terminology in regard to herniation of the intervertebral disk. This standard reporting terminology may be used with CT or MR imaging and is useful to report the location and size of the disk herniation. Recommendations are to report abnormalities in zones on axial images and in levels on the sagittal and coronal images. The diagnostician must also be aware of the various pitfalls associated with disk herniation to avoid the scenario of surgical intervention at the incorrect spinal level.

Percutaneous augmentation of the superior pubic ramus with polymethyl methacrylate: treatment of acute traumatic and chronic insufficiency fractures.

The injection of polymethylmethacrylate (PMMA) is a minimally invasive image-guided procedure that is typically used to treat vertebral body fractures due to osteoporosis or neoplastic involvement. The injection of PMMA into various other locations including the sacrum, acetabulum, pedicles, femur and tibia has been reported previously, and these procedures have, overall, been highly effective at alleviating pain and discomfort. Although the injection of PMMA into the vertebral body is a very common procedure that has been performed for over 2 decades for the percutaneous treatment of vertebral body fractures, the percutaneous injection of PMMA has not been reported in the English literature as treatment for superior pubic ramus fractures. We report the percutaneous treatment of an acute superior pubic ramus fracture and of a chronic insufficiency fracture of the superior pubic ramus using a parasymphyseal approach to access the region of injury.

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.

Gnathodiaphyseal dysplasia.

Gnathodiaphyseal dysplasia (GDD) is an orthopedic condition involving cemento-osseous lesions of jaw bones, sclerosis, bowing of tubular bones, and overall bone fragility. This is a case report of GDD in which an 18-year-old female presented with a several-year history of bony abnormalities of the jaw and long bones. Radiographs demonstrated endosteal thickening, bowing of long bones, and abnormalities of the skull. These findings, along with the patient's known maxillary region cementoma, led to a diagnosis of GDD.
