Traumatic pseudoaneurysm of the brachial artery.

Detection and treatment of vascular injuries in extremity and pelvic trauma can be challenging. Angiography, while no longer routinely used in asymptomatic patients, is still a primary means of diagnosis. Appropriate patient selection based on physical examination, along with other less invasive imaging modalities, can decrease the need for angiography while still detecting the vast majority of clinically significant injuries. Angiography also plays a definitive therapeutic role in most cases of significant hemorrhage in the pelvis through precise identification and selective embolization of bleeding vessels.

Flexion and traction effect on C5-C6 foraminal space.

OBJECTIVE: To determine the effects of cervical flexion and traction on foraminal volume and isthmus area at the C5-C6 foraminal space in cadavers. DESIGN: This study evaluated the foraminal space at C5-C6 in cadaver specimens during flexion and traction of the cervical spine. SETTING: An orthopedic biomechanics laboratory and department of radiology of a university medical center. PATIENTS OR OTHER PARTICIPANTS: Nine cadaver cervical spines, C1 through T3, were used in the study. Superficial tissues were dissected, preserving the ligaments. INTERVENTIONS: Proximal and distal portions of the cadaver spines were potted using bone cement. Spines were mounted and imaged with computed tomography in neutral position, 15 degrees of flexion, and maximum flexion with and without 25lbs of axial traction. MAIN OUTCOME MEASURES: The areas and volumes of the foramen were measured and calculated. RESULTS: Flexion alone significantly increased the foraminal volume and isthmus area at C5-C6. Traction resulted in little additional change. CONCLUSIONS: For cervical spines with mild to moderate degenerative changes at C5-C6, cervical flexion with or without traction produces significant increases in foraminal volume and area at the foraminal isthmus.

Does radiographic osteoarthritis correlate with flexibility of the lumbar spine?

OBJECTIVES: To examine the association between radiographic lumbosacral (LS) osteoarthritis (OA) and lumbar flexibility in elders without back pain or known spinal pathology and to develop a reliable grading system for osteoarthritis of the lumbosacral spine. DESIGN: Cross-sectional study. SETTING: Durham VA and Duke University Medical Center Department of Radiology. PARTICIPANTS: 35 volunteers aged 64-90 (nursing home residents and community dwellers). Exclusion criteria were known spinal pathology, back pain, inability to stand independently for 1 minute, and > 150% of ideal body weight. INTERVENTIONS: All subjects underwent LS spine radiographs and flexibility measures (forward flexion, extension, lateral flexion, and axial rotation). MAIN OUTCOME MEASURES: Reliability of ordinal OA X-ray grading system, tested using intraclass correlations (ICCs); stability of flexibility measures, using ICCs; and association of disc or facet summary scores (sum of all levels, T12 thru S1) with flexibility measures, using Pearson correlations. RESULTS: ICCs for interest flexibility measures ranged from 0.72 to 0.94. ICCs for interobserver X-ray scores were 0.85 for facet disease and 0.93 for disc disease. The correlation of facet disease with forward lumbar flexion was 0.29. The correlation of disc disease with flexibility showed modest correlation for forward (r = 0.34), right lateral (r = 0.36), and left lateral (r = 0.35) flexion. None of the correlations was influenced by age. CONCLUSIONS: We have developed a reliable radiographic scoring instrument for assessing radiographic OA of the LS spine. It appears that painless LS disc OA is one factor that influences spinal motion.

CT appearance of lunate trachea.

Computed tomography provides excellent visualization of the trachea, but there have been only limited descriptions of variations in tracheal shape. The normal tracheal cartilage is U shaped. Lunate shaped trachea is uncommon and is characterized by a coronal/sagittal diameter ratio (tracheal index) greater than 1. We present the CT appearance of a lunate shaped trachea with corresponding pathologic sections. Destruction of the membranous septum caused marked increase in the tracheal index in this patient.
