Olecranon bursitis is rarely seen in patients with stroke, but reflex sympathetic dystrophy syndrome is not. Here, we report a stroke case, which represented the clinical symptom of reflex sympathetic dystrophy syndrome after development of olecranon bursitis in few days, and describe his clinical association between both conditions. Sonographicpicture of the right elbow in this case is shown.
Olecranon bursitis (OB) is rarely seen in patients with stroke, but in contrast, reflex sympathetic dystrophy syndrome (RSDS) is not true. RSDS is anactual condition definited by localized or diffused pain [
A 53-year-old man was admitted to our hospital on 24 December 2010 for inpatient rehabilitation after transference from another hospital following cerebral infarction in the left hemisphere on 23 October 2010. Three weeks after admission, the patient suffered from painful swelling of the right elbow region, which continued to worsen. The local swelling raised with increased temperature in the lesion side (
Shortly after the procedure, the patient grumbled strong sharp pain accompanied withdiffuse swelling of his right upper limb, particularly in the wrist region. The pain worsened while stretching the elbow and wrist joints, which was particularly obvious at night. The diagnosis of RSDS of the right hemiplegic limb was made by physical examination as well as triple phase bone scan, which was performed on 24 January 2011, and revealed mildly to moderately increased tracer uptake during the arterial and soft-tissue phases, and moderately to markedly at the right wrist and MP joints of the right hand (
Rehabilitation modalitytreated the dystrophic condition with some benefit. Another OB took place in the left elbow one month later, but remitted spontaneously in one week.
This is the first report describing the development of OB and RSDS in the same limb. OB is commonly seen in players in sports, such as wrestling, weight lifting, gymnastics, skateboarding, and rollerblading, particularly when they do not wear elbow protection. OB is also common seen in clinical practice, which etiology can be distinguished as septic and aseptic. There are various kinds of organism resulting in OB, including bacteria, Tubercle Bacillus, fungus, protothecosis etc. The aseptic OB can be related to systemic inflammatory disease, for instance, rheumatoid arthritisor gouty arthritis. According to the literature, the only possible factor contributing to both conditions is infection, but the aspirated bursal fluid failed to confirm the existence of an infection in our patient. The elbow region is the dependent part of the upper limb in supine or seated position, and it may had some degrees of vascular or nerve compromise when it is compressed. We hypothesized that motor deficit might contribute to localized inflammation after repetitive microtrauma, which inflammation result in the subsequent OB.
The peculiar phenomenon of RSDS characterized by autonomic dysfunction and severe pain that may lead to contracture of the affected limbs [4,5]. The incidence for RSDS in the affected paretic upper extremity after stroke varies between 1.5% and 61% [
induce RSDS, in some degrees.
The exact cause of RSDS had not been understood well. The development of unilateral sweating abnormalities after stroke led to the hypothesis that autonomic disturbances occurred in stroke and RSDS might share a common central pathophysiology [
This report describes the development of RSDS following OB in a hemiplegic limb, and we emphasized that the important role of motor deficit in hemiplegic limb, because it did not happen in the healthy limb even OB occurrence.
