Purpose: Compression of the ulnar nerve in the ulnar tunnel is a relatively uncommon condition. Many authors have described several etiologies of ulnar nerve compression. We experienced two cases of ulnar nerve compression in the ulnar tunnel due to an anomalous pulsatile S - shaped ulnar artery. Methods: Case 1: A 51 - year - old man was referred with numbness and paroxysmal tingling sensation along the volar side of the ring and little fingers of his right hand for 6 months. When exploration, the ulnar artery was pulsatile S - shaped and was impinging on the ulnar nerve. To decompress the ulnar nerve, the tortuous ulnar artery was mobilized and translocated radially onto the adjacent fibrous tissue. Case 2: A 41 - year - old man was referred with tingling sensation on the 4 th, 5 th finger of the right hand for 4 months. Sensory nerve conduction velocities of the ulnar nerve was delayed. Preoperative 3D angio CT scan showed an anomalous S - shaped ulnar artery. Same operation was done. Results: The postoperative course was uneventful. After decompression, paroxysmal tingling sensation decreased to less than 1 minute per episode, occurring 1 - 2 times a day. After 4 months, they had no more episodes of numbness and tingling sensation. Examination demonstrated good sensation to pinprick and touch on the ulnar aspect of the hand. Conclusion: We report two cases of ulnar nerve compressive neuropathy that was caused by an anomalous pulsatile S - shaped ulnar artery in the ulnar tunnel. Although this is an unusual cause of ulnar nerve compression, the symptoms will not spontaneously resolve. The prompt relief of compressive neuropathic symptoms following the translocation of the impinging ulnar artery from the affected ulnar nerve onto adjacent tissue proved that the ulnar nerve compression is due to the anomalous vessel.

목적: 척골 신경병이 동반된 주관절의 퇴행성 관절염에서 최소 절개 척골 신경 감압술과 동시 시행한 관절경적 변연 절제술의 효과를 알아보았다. 대상 및 방법: 2006년 5월부터 2014년 7월까지 43명을 대상으로 최소 절개 신경 감압술만 시행받은 18예를 1군, 관절경적 변연 절제술과 신경 감압술을 동시 시행받은 25예를 2군으로 나누어 분석하였다. 술 전과 술 후 6개월의 통증 점수, 관절 운동 범위, Mayo elbow performance score (MEPS), disabilities of the arm, shoulder and hand (DASH), McGowan grade, Bishop rating score를 분석하였다. 결과: 두 군 간의 통증 점수, 관절 운동 범위, MEPS, DASH 호전 정도는 차이가 없었다. McGowan grade는 각각 1예를 제외하고 모두 1등급 이상의 호전을 보였으나 2군이 유의하게 더 우수하였고(p=0.001), Bishop rating score도 2군이 유의하게 더 우수하였다(p=0.036). 결론: 척골 신경병이 동반된 주관절 퇴행성 관절염에 대하여 최소 절개 척골 신경 감압술과 동시에 시행한 관절경적 변연 절제술은 관절 기능 향상과 척골 신경 회복에 유용한 술식이다.

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.

Eletrophysiological methods revealed subclinical neuropathy in 26 workers, exposed from 1 to 17 years to lead and whose blood lead (PbB) values had never exceeded $70{\mu}g/100\;ml$, as ascertained by checking the monitor reports of the factory and by careful exposure history. The PbB determinations had been tested repostedly and had been found valid. The main findings were slowing of the maximal motor conduction velocities of the median and ulnar nerves and particularly the conduction velocity of the slower fibers of the ulnar nerve. Eletrophysiological abnormalities comprised fibriliations, diminution of the number of motor units on maximal contraction, and an abnormal. Thus, a dose-response relationship exlets on a group basis. Since the regular monitoring of PbBs in most workers during their entire period of exposure excludes the possibility of a body burden out of proportion to the PbBs silght neuro-logical damage is produced at exposures hitherto regarded as quite sale.

Two cases of bilateral ulnar neuropathies caused by telephone overuse are described in people engaged in the job of longtime telephone use. They had worked using telephone all through the working hours. Although they were right handed, they usually used the telephone in their left hand so as to leave their right hand free for writing, and would lean his elbow on the desk. Telesales or teleconsultation is a rapidly expanding field of business. These cases highlights the need of proper training and supplies appropriate to do their job.

The Outerbridge-Kashiwagi (O-K) procedure is one of popular procedures for the treatment of osteoarthritis of the elbow. Although reliable outcome has been reported in the literature, intraoperative and postoperative complications may occur. Acute postoperative neurologic complications are rarely reported in the literature. We report a case of acute complete ulnar neuropathy following O-K procedure in the elbow with longstanding flexion loss. Prophylactic ulnar nerve decompression during the O-K procedure should be considered in the elbows with osteoarthritis and prolonged severe flexion contracture.

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.

Background The clinical results of conservative treatment options for ulnar compression at the elbow have not been clearly determined. The aim of this review was to evaluate available conservative treatment options and their effectiveness for ulnar nerve compression at the elbow. Methods In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, a systematic review and meta-analysis of studies was performed. Literature search was performed using Ovid MEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL). Results Of the 1,079 retrieved studies, 20 were eligible for analysis and included 687 cases of ulnar neuropathy at the elbow. Improvement of symptoms was reported in 54% of the cases receiving a steroid/lidocaine injection (95% confidence interval [CI], 41-67) and in 89% of the cases using a splint device (95% CI, 69-99). Conclusions Conservative management seems to be effective. Both lidocaine/steroid injections and splint devices gave a statistically significant improvement of symptoms and are suitable options for patients who refuse an operative procedure or need a bridge to their surgery. Splinting is preferred over injections, as it shows a higher rate of improvement.

공기주입 구혈대 사용 시 가장 흔히 발생할 수 있는 합병증인 신경손상은 실제 발생은 드물며 발표된 증례도 많지 않다. 저자들은 상지 수술 후 발생한 신경손상 2예를 통해 이러한 위험을 알리고자 한다. 좌수 재건을 위해 수술을 받은 남성 환자에서 통상적인 감압 휴지기를 가졌음에도 불구하고 요골, 정중, 그리고 척골 신경의 손상이 확인되었고 이는 14시간의 총 누적 적용 시간으로 인한 결과로 추정되었다. 수부 압궤손상으로 재건 수술을 받은 여성 환자는 요골 신경 손상이 발생하였으며 수술 중 구혈대의 오작동으로 인한 사례로 추정되었다. 이 증례들은 구혈대로 인한 신경손상의 다양한 임상소견이 신경검사 결과와 불일치할 수 있으며, 장기간 불편을 야기하는 이 합병증을 예방하기 위해 구혈대 사용 시 주의를 요할 점들을 시사해준다.
