US evaluation of the rotator cuff.

Ultrasonographic (US) evaluation of the moving shoulder is a new method for evaluating the integrity of the rotator cuff. In the past, contrast arthrography has provided the only nonoperative technique for demonstrating defects in the rotator cuff. We present the details of this new technique and describe 79 patients whose US results were correlated with the findings at arthrography and/or surgery. US allows evaluation of both shoulders at once, an advantage over arthrography, where usually only one side is evaluated at a single sitting. Improvements in US instrumentation, especially the introduction of high-resolution linear-array devices and the use of experienced ultrasonographers, have improved the accuracy of US. Because US is rapid, safe, noninvasive, and inexpensive, we advocate its use instead of arthrography as the routine test of rotator cuff integrity.

Leg length determination by CT digital radiography.

CT digital radiography is a new accurate technique for measuring leg length discrepancy. It is easily performed on commercially available equipment with a radiation dose of 3-6 times less than the conventional technique. Because of the short time required to complete the examination, charges are comparable with those for existing procedures. Good correlation in total limb length measurements between this new technique and spot scanography was noted in 24 patients. CT digital radiography should be the preferred method for evaluation for limb length discrepancy, particularly in children, because of the simple technique and lowering of radiation dose.

Computed tomography in evaluation of gunshot wounds of the spine.

Seven patients with gunshot wounds to the cervical, thoracic, or lumbar spine were evaluated with conventional radiography, complex motion tomography, and computed tomography (CT). Computed tomography was better than complex motion tomography or conventional radiography for the assessment of the presence of fracture(s), bony and metallic fragments, and associated soft tissue injuries. In each case CT provided additional information not available by the other techniques.

Thoracolumbar spine injuries associated with vertical plunges: reappraisal with computed tomography.

Eighteen patients who had fallen or jumped, and who had sustained fractures of the thoracolumbar spine, were examined with high-resolution computed tomography (CT). Two distinctive patterns of fracture were demonstrated: compression, or wedge, fractures of the vertebral body were present in seven patients, but they were not associated with permanent neurological deficit; and burst fractures with sagittal cleavage into two fragments occurred in five of 11 patients, and they were associated with permanent neurological deficit. CT provided precise and unique information that aided in clinical decision making for this group of patients.

Rotator cuff tear measurement by arthropneumotomography.

Five years of experience with a method of shoulder arthrography using upright tomography in cases of suspected or known rotator cuff tears has demonstrated its effectiveness. The value of the procedure lies in its ability to demonstrate the size of the cuff tear and the thickness of the remaining cuff tissue. This information provides the surgeon with a preoperative estimate of the difficulty of the repair and the prognosis for a good functional recovery. In 33 cases, there was good correlation between the upright thin-section tomogram findings and the surgical results. The tomograms provided better information about the size of the tear and the quality of the remaining cuff than did plain arthrograms.

Double-contrast computed tomography of the glenoid labrum.

Imaging of glenoid labrum pathology is useful to help plan surgical repair of the dislocating shoulder. Eleven patients with suspect labrum damage were imaged with computed tomography (CT) immediately after routine double-contrast shoulder arthrography. Lesions identified included attenuation, tears, and displacement of the labrum as well as stripping and stretching of the anterior shoulder joint capsule. Surgical confirmation of pathology was available in all but one case. CT of the glenoid labrum is easy to perform, low in radiation dose, and accurate.

The ligaments of the human wrist and their functional significance.

The ligamentous anatomy of the wrist was analyzed by studying (1) 28 dissected human wrists, (2) and by examination of 19 wrist injuries created mechanically. Six volar intracapsular ligaments are described, two stabilizing the distal carpal row, three stabilizing the proximal carpal row and one stabilizing the proximal scaphoid pole. More specific terminology for these ligaments is proposed. An explanation of how these ligaments participate in the mechanical functioning of the carpus is advanced. Mechanically created wrist injuries had ruptures of specific ligaments as described augmenting a need for a more specific terminology. Suspected mechanisms of injury in perilunate and lunate dislocations are mentioned based upon the functional understanding of the intracapsular ligaments.
