Abstract

Thickening of finger extensor tendons in hemiplegic hands of stroke patients has never been reported. We reported 11 patients with stroke who experienced gradual onset of a painless swelling at the dorsal aspect of the hemiplegic wrist. Soft tissue sonography revealed that the swellings were mainly composed of thickened finger extensor tendons. This thickening typically involved the tendons of the 4th dorsal extensor compartment between the proximal carpal and mid-metacarpal levels. The maximal thickness of these tendons could reach over three times that of the corresponding tendons of the contralateral hand. The synovial tissue surrounding the thickened tendon was also thicker than normal. Our preliminary data indicated that tendon thickening could become evident as early as 4 weeks post-stroke, and is usually most prominent from 2 to 6 months post-stroke. We concluded that thickening of finger extensor tendons of hemiplegic hands was a common clinical phenomenon in patients with stroke, and should be regarded as one of the major differential diagnoses of swelling at the dorsal aspects of the wrists and hands of these patients. This paper will discuss the possible causes of this phenomenon.
