Abstract

We describe a film subtraction method using computer processing. The computer processed subtraction arthrograms in 16 cases were compared with conventional photographic subtraction. Although the computer reduced image resolution, it presented significant advantages over photographic film subtraction, including faster access to subtraction, optimal superimposition of mask and postinjection films by the radiologists, reduction of artifacts, and time saved.

[Parsonage-Turner syndrome complicated by sympathetic dystrophy syndrome with adhesive capsulitis of the shoulder. Apropos of 2 cases].

Two typical cases of Parsonage-Turner syndrome with reflex sympathetic dystrophy syndrome and adhesive capsulitis of the shoulder are reported. The rarity of this combination is discussed.

Contrast arthrography in thumb polydactyly with variable morphological patterns.

Contrast arthrography was performed in 20 patients with duplicated thumbs where the interphalangeal, metacarpophalangeal, and carpometacarpal joints were involved. Three groups were apparent, those with no joint alteration, those with joint involvement and separate articular impressions, and those with abnormal duplex joints.

Arthroscopic elbow findings: correlation with preoperative radiographic studies.

Correlation between arthroscopic findings and preoperative radiographic studies (plain radiographs and arthrotomograms) was performed in a consecutive series of 37 elbows. Arthrotomograms added significant diagnostic information unavailable from plain radiographs alone, thereby improving the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic efficiency (accuracy) in the evaluation of elbow joint surface changes, marginal spurs, and loose bodies. Arthrotomograms gave 85% accuracy for bone spurs, 89% accuracy for joint surface abnormalities, and 89% accuracy for loose bodies (88% accuracy overall), whereas plain radiographs demonstrated 69% accuracy for bone spurs, 71% accuracy for joint surface abnormalities, and 75% accuracy for loose bodies (72% accuracy overall). The arthrotomograms had 100% sensitivity for loose bodies as well as a 100% negative predictive value for loose bodies. Arthrotomograms are indicated when additional preoperative diagnostic accuracy is necessary. These radiographic studies approached only 90% accuracy, confirming that diagnostic arthroscopy adds additional information.
