The sonographic findings in seven patients with surgically proved acute tenosynovitis of the hand (bacterial in six cases, of presumed viral origin in one) were reviewed. In the six patients with bacterial tenosynovitis the affected flexor tendon was larger than that of the contralateral normal digit. ⋯ The affected tendon of the single patient with tenosynovitis thought to be of viral origin was normal in size, but a focal tendon sheath fluid collection was detected that proved to be sterile at surgery. Sonography appears to be a useful imaging technique in the early diagnosis of acute suppurative tenosynovitis of the hand.

One of the potentially troublesome sequelae of limb amputations is the development of stump neuromas at the severed ends of major nerves. The ability to define them and to distinguish them from other causes of stump pain is of considerable clinical significance. ⋯ Five patients had neuromas that were manifest as focal or generalized alteration in the caliber, size, or contour of the nerve trunk in the affected stump. The remaining five patients each had an abnormality detected; these abnormalities included heterotopic bone formation, popliteal artery aneurysm, lipoma, scar tissue, and abscess in the contralateral limb.
