Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy caused by focal compression of the median nerve in the carpal tunnel. However, many patients with CTS, who are diagnosed clinically and confirmed with electrophysiological studies, complain of the sensory symptoms extends to the ulnar nerve territory. The aim of this study was to evaluate whether a dysfunction in sensory fibers of the ulnar nerve was present or not in hands with CTS patients who had extramedian spread of sensory symptoms over the hand. We retrospectively analyzed the recording of the subjects who were diagnosed with CTS within a one-year-period of time. After exclusions, 136 hands recordings of 87 patient were included. We compared the results of median and ulnar nerve sensory conduction studies between normal hands and hands with CTS. We did not detect statistically significant difference on all parameters of ulnar nerve sensory conduction studies between the normal hands and the hands with CTS. The parameters of the obtained in median nerve sensory conduction studies were statistically different between the healthy control and CTS patients. The hands with CTS showed similar rate of ulnar sensory conduction abnormalities compared with the normal hands. In conclusion, our study showed that none of the parameters in ulnar sensory nerve conduction studies differ between two groups. Accordingly, our study revealed that ulnar nerve involvement does not contribute in CTS patients underlying the spread of paresthesia extends to the ulnar nerve territory.

Double compression of the ulnar nerve, including Guyon's canal syndrome associated with cubital tunnel syndrome caused by the anconeus epitrochlearis muscle, is a very rare condition. We present a case of double crush syndrome of the ulnar nerve at the wrist and elbow in a 55-year-old man, as well as a brief review of the literature. Although electrodiagnostic findings were consistent with an ulnar nerve lesion only at the elbow, ultrasonography revealed a ganglion compressing the ulnar nerve at the hypothenar area and the anconeus epitrochlearis muscle lying in the cubital tunnel. Careful physical examination and ultrasound assessment of the elbow and wrist confirmed the clinical diagnosis prior to surgery.

Compression of the ulnar nerve in Guyon's canal can result from repeated blunt trauma, fracture of the hamate's hook, and arterial thrombosis or aneurysm. In addition, conditions such as ganglia, rheumatoid arthritis and ulnar artery disease can rapidly compress the ulnar nerve in Guyon's canal. A ganglion cyst can acutely protrude or grow, which also might compress the ulnar nerve. So, clinicians should consider a ganglion cyst in Guyon's canal as a possible underlying cause of ulnar nerve compression in patients with a sudden decrease in hand strength. We believe that early decompression with removal of the ganglion is very important to promote complete recovery.

We experienced two cases of ulnar nerve palsy caused by a ganglion that were managed by excision of the ganglion performed concurrently with subcutaneous anterior transposition of the ulnar nerve. Satisfactory results were obtained. The possibility of ulnar nerve compression by ganglion must be considered in patient who complains rapidly progressing ulnar nerve palsy. For those cases, ultrasonography or magnetic resonance imaging seems to be helpful in obtaining preoperative diagnosis.

As a surgical treatment of ulnar nerve entrapment syndrome includes simple decompression, medial epicondylectomy, and anterior transposition of the ulnar nerve into a subcutaneous or submuscular bed have been widely used. Despite many reports of these surgical procedure, there is little to guide the choice of one surgical technique. The purpose of our study is to analyse clinical and electrodiagnostic result after minimal invasive decompression by decompression and medial epicondyloplasty(deepening of ulnar groove). We have experienced 9 cases of ulnar nerve entrapment syndrome who were treated with decompression and medial epicondyloplasty. Male were five and female were four. The mean age at operation was 36 years ranging from 23 to 47 years. Operative procedure was to incise the medial intermuscular septum and aponeurotic arch of flexor carpiulnaris and to deepen the ulnar groove. Patients are allowed to do range of motion(ROM) exercise on the average 5days. All patient were relieved pain and improved motor and sensory function, and this procedure allows early ROM exercise after operation because the muscle have not been detached.

It is well known that tardy ulnar nerve palsy occurs with cubitus valgus deformity as a late complication after a nonunion of lateral condyle fracture of the humerus in childhood. On the other hand, cubitus varus deformity often results from malunion of supracondylar fractures of the humerus. However, reports of tardy ulnar nerve palsy in cubitus varus deformity are few. We report a patient with bilateral cubitus varus deformities with bilateral tardy ulnar nerve palsy which was confirmed with EMG. She was treated by step cut osteotomy(DeRosa and Graziano) with sub­cutaneous anterior transposition of ulnar nerve.

Purpose: The aim of this study was to evaluate preoperative ultrasonographic findings and usefulness in ulnar neuropathy around elbow. Materials and Methods: Twenty-two patients with ulnar neuropathy were performed preoperative ultrasonogram. The route, location, thickness of the ulnar nerve and space occupying lesion through longitudinal scan were evaluated. Cross-sectional areas of the ulnar nerve were measured at the level of medial epicondyle and 3 cm proximal and distal to the medial epicondyle through axial scan. Correlations between swelling ratio of ulnar nerve and eletrophysiologic study and preoperative Dellon's assessment were checked. Results: In 21 cases (95.6%) of total 22 cases, diffuse swelling of the ulnar nerve around elbow were identified. 4 cases had space occupying lesions including 3 ganglionic cysts and 1 heterotopic ossification. Cross sectional areas at the level of medial epicondyle were significantly larger than at the level of 3 cm proximal and distal to the medial epicondyle (p<0.05). There were no statistically significant correlations between swelling ratio of ulnar nerve and eletrophysiologic study and preoperative clinical assessment (p>0.05). Conclusion: This study showed that ultrasonography was helpful to detect etiology of ulnar neuropathy around elbow such as space occupying lesion, morphological change or dislocation of ulnar nerve. It could be useful tool for diagnosis and treatment in patients with ulnar neuropathy at elbow.

Purpose: Radial and ulnar arteries are two major arteries responsible for the blood supply of the hand. We experienced early recurrent thrombosis of ulnar artery after arteriorrhaphy in a patient with rupture of ulnar and radial arteries due to glass injury. Thus, we thought this would require reviews. Method: 41 - year - old female patient was presented for the laceration of right wrist due to glass injury. Operative findings revealed the rupture of radial artery, ulnar artery, ulnar nerve and most of the flexor tendons. We performed three consecutive operations because of the recurrent arterial thrombosis in ulnar artery. Arteriorrhaphy was performed in each operation and the interpositional vein graft was performed in the final operation. Result: Consequently, doppler ultrasonography was performed on twentieth postoperative day and fair flow in the ulnar artery was visualized. Pathologic examination of the artery revealed no histopathologic abnormalities. Conclusion: It is not a matter of ease to follow up the patients with rupture of radial or ulnar arteries. Obstruction of the repaired artery is also not easy to detect because it usually presents no definite symptoms. We could detect the obstruction of the artery following arteriorrhaphy with the doppler ultrasonography in less than a week postoperatively, and repeated operations were followed. We reviewed the causes and factors affecting the thrombosis and hereby report with literature review.

Cubital tunnel syndrome refers to compression neuropathy caused by pressure on the ulnar nerve pathway around the elbow. A 63-year-old male patient visited the clinic complaining of decreased sensation and weakness in his left ring finger and little finger, stating that the symptoms first began 6 months prior. He had undergone surgery to remove a ganglion cyst from his left elbow joint about 5 years prior in Mongolia. Magnetic resonance imaging revealed a cystic mass located at the previous surgical site, which was compressing the ulnar nerve within the cubital tunnel. Ulnar nerve decompression and anterior transposition were performed, and the cystic mass was excised. Upon pathological examination, the mass was diagnosed as a ganglion cyst. The patient's symptoms including sensory dysfunction and weakness improved over the 1-year follow-up period. This report describes a rare case of ganglion cyst recurrence compressing the ulnar nerve in the cubital tunnel after previous ganglion cyst excision.

Objectives: This study examined the natural history of symptomatic patients who did or did not display abnormal results on nerve conduction studies (NCS). Methods: Forty hundred fifty adults were selected among a total of 578 residents who participated in the health examination in a rural Korean district. A symptom questionnaire and NCS were used to diagnose ulnar neuropathy at the elbow (UNE). There were 6.4% of the subjects with UNE, 5.1 % of the subjects showed symptoms without a NCS, and 84.2% of the subjects who were asymptomatic. One year later, 20 symptomatic limbs with an abnormality on the ulnar NCS and 22 symptomatic limbs without any abnormality in the ulnar NCS were enrolled in a follow-up study. The natural history of UNE was evaluated by examining the changes in the clinical and electrodiagnostic examinations. Results: The 1-year follow-up of the enrolled limbs found that for the symptomatic limbs with an abnormality on the NCS, the degree of severe of the clinical grade changed from 20% to 10%. In contrast, for the symptomatic limbs that were without any abnormality in the NCS, the change of the severe degree of the clinical grade was from 0% to 18.2%. Also, for the electrodiagnostic change, only symptomatic limbs without NCS abnormalities showed significant changes in motor latency, amplitude and conduction velocity at the 1-year follow-up. Conclusions: The 1-year follow-up study revealed symptomatic limbs that were without any abnormality on the ulnar NCS were more likely to progress than the symptomatic limbs with an abnormality on the ulnar NCS.
