Objective:
To investigate the causes and the characteristics of acute aggravating cubital tunnel syndrome.
Methods:
The enrolling criteria of subjects were as follows: (1) Patients with manifestation of cubital tunnel syndrome for more than 6 months; (2) acute exacerbation of the disease for no more than 4 weeks. The clinical data from March 2011 to December 2014 was collected and analyzed retrospectively. Twelve cases aged 52 to 65 met the enrolling criteria and were included in this study, and among them 10 patients were male, 2 were female; 5 cases were on the left and the other 7 on the right. All of them had some degree of cubital tunnel syndrome symptoms before the onset of acute exacerbation.
Results:
When nerve decompression and anterior transposition of the ulnar nerve was performed, the elbow joint cysts which squeezed the ulnar nerve were found. The cysts were then resected. In all 12 cases, the compression symptoms of ulnar nerve were relieved after surgery. The mean follow up period was 13 months, ranging from 6 to 45 months. According to Gu Yudong functional evaluation criteria for cubital tunnel syndrome, 2 of the patients can be judged as "Excellent", 8 "good" and 2 "acceptable" at the follow-up.
Conclusions:
Cyst compression may induce the acute exacerbation of ulnar nerve symptom in patients with cubital tunnel syndrome. Early diagnosis and treatment is critical for these patients.
