Purpose: The aim of this study was to determine the effectiveness of arthroscopic debridement with mini-open ulnar nerve decompression in primary osteoarthritis of the elbow with ulnar neuropathy. Materials and Methods: Between May of 2006 and July of 2014, a total of 43 patients who had undergone surgery for primary osteoarthritis of the elbow with ulnar neuropathy were included in this study. We divided the subjects into two groups according to the method of surgery: group 1 (n=18) received mini-open ulnar nerve decompression only, and group 2 (n=25) received arthroscopic debridement with mini-open ulnar nerve decompression. Patients were assessed for the following clinical outcomes: visual analogue scales (VAS) score, range of motion of the elbow joint, Mayo elbow performance score (MEPS), and disabilities of the arm, shoulder and hand (DASH) at the time before surgery and 6 months after surgery. We analyzed the recovery of the ulnar nerve by the McGowan grade and Bishop rating score preoperatively and at 6 months after the surgery. Results: The VAS score, range of motion of the elbow joint, MEPS, and DASH showed significant statistical difference after the surgery (p<0.05). However, between the 2 groups, there was no significant difference. For the McGowan grade, all cases of both groups-except one case each group-showed at least one grade improvement. Moreover, group 2 showed a greater significant difference than group 1 (p=0.001). At the final follow-up, according to the Bishop rating score, group 2 had a greater significant difference than group 1 (p=0.036). Conclusion: Arthroscopic debridement with mini-open ulnar nerve decompression in primary osteoarthritis of the elbow with ulnar neuropathy is a useful technique, which has several advantages, including the benefits associated with a minimally invasive surgery and also the improvement of elbow joint function and excellent recovery of the ulnar nerve.

신경외과는 뇌수술과 척추수술로 나눈다. 이중뇌수술 분야에서는 두개강내압 항진시 감압술이라고 '머리의 뚜껑을 연다'라는 표현과 마찬가지로 두개골의 일부분(손바닥크기)을 절제하는 수술이 있다. 이때 과거에는 떼어낸 뼈를 복부의 피하지방밑에 심어서 보관을 하다가 3-6개월 후 환자의 뇌상태가 안정이 되면 다시 꺼내어 제자리에 놓았는데, 골편이 피하지방에서 녹는 경우가 다소 있고, 복부에 이식한 장소가염증이 생기는 경우도 있어서 요즘은 냉동고에서 -70도를 유지하여 보관 후 나중이 복원 수술을 할 때녹여서 사용한다. 이를 '자가골 두개성형술' 이라 한다. 하지만골편의 오염이나 소실 혹은 1차 두개성형술 후 감염 등 어쩔 수 없이 자가골을 사용 못하는 경우에는인공으로 두개골편 모형을 제작하여 '뚜껑'으로 사용해야 한다. 현재PMMA를 이용하여 수술 시 모형을 제작하는 방법이 많이 사용되며 최근 단단한 스펀지 형태의 인공제품이 사용되고 있으나 가격이 매우비싸지만 스펀지 기공내로 자가골이 자란다는 장점이 있다. 척추수술 분야에서는 뼈 대치품을 비교적 많이필요로 한다. 즉 척추 후방고정을 하는 경우 원래 수술의 목적인 감압술이나 교정술 등을 한 후 척추분절간 쇠(티타늄사용)고정을 한 뒤에 뼈조직(자가골이나 동종이식골, DBM, HA stick) 등을 충분히 사용하여덮어줌으로써 분절간 골유합을 유도할 때 많은 양이 필요하며, 척추 전방으로 수술을 하는 경우에도 디스크공간이 빈 상태에서 Cage(추체와 추체를 지지하는 작은 상자모양) 내에뼈조직을 넣어서 척추분절간 골유합이 일어나도록 한다. 최근 HA를 cage 대용품으로 사용한 경우에서 HA가 부서지는 경우가 기사화된바 있다. 또한 경추의 추체 내에 작은 구멍만 뚫고 디스크 수술을 한 후에 그 구멍에 HA+B-TCP 소재를 넣어 천연뼈의 성장 유도를 위해 사용되는 등 신경외과의 다양한 분야에서 생체소재들이 사용되고 있다.

This study was performed to evaluate the effects of the combination of electroacupuncture (EA) and surgical decompression on paraplegia due to spinal compression in dogs. Ten clinically healthy dogs were assigned into two groups (group A and group B). The one is for the combination of EA and surgical decompression, and the other is for surgical decompression alone. After decompression, neurological function was evaluated daily with modified Tarlov grading system. SEPs were measured as objective evaluation of normal spinal cord function before spinal compression and after neurological recovery. The period of rehabilitation in group A was significantly shorter than that in group B (p<0.05). Conduction velocity of SEPs showed a tendency to return to normal when the dogs got full recovery. According to these results, it was considered that the EA with surgical decompression was more effective than surgical decompression alone for paraplegia resulting from spinal cord injury in dog.

In the patient who has intradural mass associated with spinal stenosis, if the operation for spinal stenosis is performed alone, the symptom may remain. We report with literature review that we achieved the successful outcome after simultaneous decompression of spinal stenosis and space occupying mass removal in the case of intradural and extradural compression. A 71-year-old female patient suffering from low back pain and radiating pain of both lower extremities admitted. In magnetic resonance imaging, spinal stenosis on L4-5 and spondylolisthesis on L5-S1 compressed dural sac and intradural space occupying mass on L4 level compressed. By posterior approach, decompression and interbody fusion were carried out. Then mass was removed with median durotomy. Pathologic diagnosis was schwannoma and the symptom was improved remarkably.

Ameloblastoma is a benign neoplasm originating from odontogenic epithelium. It is the most common neoplasm in the jaws and is characterized by aggressive behavior and local invasion. Unicystic ameloblastoma (UA) has a unilocular feature in radiologic examination and a cystic feature histologically. Decompression and marsupialization are conservative method of treatment of large UA. The purpose of decompression and marsupialization are size reduction of the mass, which makes it easy to handle at total enucleation with protection of nerve damage and facial deformity. Here we report successful conservative treatment of extensive UA using decompression and marsupialization with a review of literatures.

Purpose: There are many known treatment modalities for spinoglenoid ganglion cyst accompanied by suprascapular nerve palsy. However, to the author's knowledge, there is no report on the follow-up outcomes focused on remnant cysts. Materials and Methods: Six (n=6) patients with spinoglenoid ganglion cyst accompanied by suprascapular nerve palsy, with a mean follow-up of 15 months (12-23months) following arthroscopic cyst decompression and superior labral repair, were enrolled. Residual cyst was investigated by ultrasonography and MRI. Results: Immediate postoperative ultrasonography revealed complete remission of ganglion cyst in one patient and reduced ganglion cyst size in five patients. Three-month follow-up ultrasonography showed spontaneous complete remission of the residual cysts in all patients. No recurrence on MRI was seen at one-year follow-up. Conclusion: Residual spinoglenoid ganglion cyst remaining after arthroscopic decompression and superior labral repair tends to resolve spontaneously within 3 months of surgery.

Purpose: Here we present tardy ulnar nerve palsy cases that were caused by the anconeus epitroch-learis muscle. Materials and Methods: A 37 year old female patient presented with tardy ulnar nerve palsy findings for the elbow. During surgery, an atypical anconeus epitrochlearis muscle was observed, which originated from the triceps aponeurosis and inserted into the medial intermuscular septum. Muscle resection, nerve decompression and ulnar nerve anterior transposition were done. A 35 year old male patient presented with tardy ulnar nerve palsy findings for the elbow. During surgery, a typical anconeus epitrochlearis muscle was found. Muscle resection, nerve decompression and ulnar nerve anterior transposition were done. Results and Conclusion: Tardy ulnar nerve palsy can be associated with and caused by either an atypical or a typical anconeus epitrochlearis muscle.

Purpose: We describe a all-arthroscopic technique for decompression of spinoglenoid ganglion cyst and present our clinical results for this procedure. Materials and Methods: From March 2006 to June 2009, eight patients (7 males, 1 female; mean age 40.6 years; range: 21~61) were included who underwent arthroscopic decompression of spinoglenoid ganglion cyst. The most common symptoms were vague shoulder pain and external rotation weakness, which lasted 6.4 months (range: 3~8) on average. Five of eight patients were noted abnormalities on electromyographic (EMG) examination to have suprascapular nerve neuropathy and magnetic resonance imaging (MRI) showed spinoglenoid ganglion cysts in all eight patients and the cyst size was 2.6 cm (range: 1.8~3.6). Labral pathology was identified intraoperatively in all patients and the cysts were decompressed by the posterosuperior capsulotomy under arthroscopic control and labral repair with suture anchors was performed in six patients. Results: The average clinical outcome scores including Constant and Murley, Simple shoulder test (SST) all improved significantly at the time of the final follow-up and there were no complications resulting from the procedures. All patients including the patients with abnormal EMG study recovered strength on isokinetic strength testing. Follow-up MRI scans were performed on all patients at a mean of 5.2 months postoperatively (range: 3~12) revealed complete resolution of the cysts and no evidence of recurrences were seen at an average of 18 months (range: 12~26) of follow-up. Conclusion: Arthroscopic decompression of spinoglenoid ganglion cyst effectively restores patient function and all patients in this study showed improvement in their postoperative MRI findings. Arthroscopic decompression is also useful in the appropriate treatment for labral pathology and may contribute to decreased risk of cyst recurrence.
