Cubital tunnel syndrome is the second most common nerve compression syndrome in peripheral nerve compression disease. Although potential ulnar nerve entrapment can occur at multiple points along its course, such as the arcade of struthers, the medial intermuscular septum, the medial epicondyle, the cubital tunnel, and the deep flexor pronator aponeurosis, the most common site of entrapment is the cubital tunnel. However, cubital tunnel syndrome could also be caused by the occupying masses along the course of ulnar nerve, such as intraneural or extraneural ganglia. The cubital tunnel syndrome caused by intraneural or extraneural ganglion cysts has been rarely reported. In our hospital, there were 184 patients with cubital tunnel syndrome who underwent surgical treatment from January 2010 to January 2014. Of these patients, 16 had extraneural cysts and 3 had intraneural ganglion cysts. The incidence rate of cysts in the cubital tunnel was 10.33%. Electromyography was used as routine examination. Ultrasound was used only in some patients in whom elbow mass was suspected. In the surgery of the cubital tunnel syndrome combined with cyst, if any other cysts were found, we should be remove completely the cyts and decompress the ulnar nerve thoroughly with the ulnar nerve being anterior transposition. These cysts were confirmed by histopathological examination. Finally, we compared the clinical features of patients who had a medial elbow ganglion with those of patients who had only cubital tunnel syndrome. B ultrasound can significantly improve the diagnosis. All patients were followed up for 4 months to 2 years, and the curative effect was good., (Copyright © 2017. Published by Elsevier Ltd.)

Introduction: This study assessed the treatment outcomes of upper extremity benign tumors using the patient-rated outcome measures of Hand20 questionnaire., Methods: In total, 304 patients who underwent surgery for benign bone and soft tissue tumors of the upper limb were included. Tumors were classified into three size groups: <1 cm, 1-3 cm, and >3 cm. Tumors were divided with respect to location: digit, hand, wrist, forearm, elbow, upper arm, or axilla. We prospectively assessed responses to the Hand20 questionnaire that was administered both before and after surgery., Results: The mean Hand20 and pain scores significantly improved after surgery in patients with ganglion cysts, giant cell tumors of the tendon sheath, enchondromas, or pyogenic granulomas. For patients with hemangiomas, schwannomas, or glomus tumors, although the mean pain scores improved significantly following surgery, there were no significant changes in the mean Hand20 scores. However, the statistical power for this analysis was low. The mean Hand20 and pain scores improved significantly, regardless of the size grouping. The mean Hand20 scores significantly improved after surgery in patients with finger, thumb, hand, or wrist tumors. Except for elbow to axillary tumors, the mean pain scores significantly improved in all patients., Conclusion: The results of Hand20 and pain scores suggest that most patients with benign hand tumors are indicated for surgery, but the degree of improvement differs according to tumor pathology and location but not size., (Copyright © 2017 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

We describe the largest reported epineural ganglion of the ulnar nerve arising in the cubital tunnel. A 54-year-old male, driver presented with progressive symptoms of left sided cubital tunnel syndrome. Surgery demonstrated a 11 × 3 cm ganglion which was successfully removed. Post-operatively the patient demonstrated partial recovery with no recurrence of the ganglion., (Crown Copyright © 2012. Published by Elsevier Ltd. All rights reserved.)
