An electron microscopic study was conducted in order to investigate the healing and maturation process of central one third of donor site patellar tendon which was used for endoscopic anterior cruciate ligament reconstruction. 17 patients among 118 consecutive series, which underwent ACL reconstruction from January 1990 to March 1995, were involved in this study according to various followup periods. At 6 months follow-up, hypercullular and randomly arranged fibrohlasts had abundant cytoplasm with marked irregular cytoplasmic borders and short cytoplasmic extensions. Thc, nuclei of fibroblasts had prominent nuclear indentation with chromatin condensation along the nuclear mernbrane and prominent nucleolus. The cytoplasm contained irregularly dilated rough endoplasmic reticulum, Golgi complex, and pinocytic vesicles. Intercellular space were occupied by newly-formed, immature col)agen fibrills without distinct parallel arrangement, and the diameter of collagen fibrils was unifoimly small. At 12 months, fibroblast and collagen fibrils showed a little matured findings except the small diameter of collagen fibrils. At 24 months, irregular-shaped fibroblasts were still present, which contained folded nuclei, ahundant cytoplasm with large amount of rough endoplasmic reticulum and Golgi complex. Collagen fihril showed also a unimodal distribution pattern with small diameter, however had a tendency to have a regular parallel arrangement. These finding suggest that the donor site of a patellar tendon was still quite different from normal patellar tendon in electron microscopic morphology even at 24 months postoperative follow-up regardless of considerable maturation of regular parallel arrangement pattern of collagen fibril.

Carpal tunnel syndrome is the most common peripheral nerve entrapment syndrome due to compression of the median nerve at the wrist. Division of the transverse carpal ligament for median nerve compression in patients with carpal tunnel syndrome is a common and successful procedure. A variety procedures exist to release the transverse carpal ligament the classic open release, limmited open or percutaneous release, and endoscopic release. From February 1994 to January 1996, 39 carpal tunnel releases were performed by percutaneous method in 30 patients (3 males and 27 females) at the Chonnam University Hospital. The patients age ranged from 42 to 67 years (average 54.8 years). The duration of the symptoms ranged from 3 months to 10 years. According to Brown's outcome analysis, results were as follows. 1. Persistent pain and paresthesia were noted in only 3 cases (7.7%) at 24 week postoperatively. 2. Two-Point discrimination on the index finger was improved significantly at 12 week postoperatively (p<0.05). In electromyographic study, conduction delay of motor and sensory fibers was diminished significantly at 4 week postoperatively (p<0.05). 3. Functional outcomes (grip strength, pinch strength, scar tenderness and return to work) were showed good and excellent result. We concluded that percutaneous decompression is one of the less morbid method for decompressing the carpal canal and relief of symptoms for the patient.

3.Comparison of Microscopic Lumbar Discectomy Between under Local and General Anesthesia in Lumbar Disc Herniation.
Journal of Korean Society of Spine Surgery 2013;20(4):129-134
STUDY DESIGN: Retrospective study. OBJECTIVES: To evaluate the effectiveness of microdiscectomy under local anesthesia in comparison with general anesthesia. SUMMARY OF LITERATURE REVIEW: No co RESULTS: Between both groups there is no significant operation time difference. However, the average hospital stay duration in the general anesthesia group was 7.3 days, while it was 4.7 days in the local anesthesia group (P<0.05). The VAS and ODI scores were improved in both groups. Thirty-two cases (84.2%) of the general anesthesia group and 40 cases (80%) of the local anesthesia group showed satismparative studies regarding the outcomes of microdiscectomy under local and general anesthesia could be found in the literature. MATERIALS AND METHODS: Between May 2000 and June 2004, 88 patients who underwent microdiscectomy under local anesthesia (n=50, local anesthesia group) or under general anesthesia (n=38, general anesthesia group) were selected and included in this study with a follow up period more than 3 years. The operation time and duration of hospital stay were documented. The Visual Analogue Scale (VAS) and the Oswestry Disability Index (ODI) were used to evaluate the degree of symptom relief. The patient satisfaction was evaluated using the MacNab's criteria and postoperative complications.fied results by the MacNab's criteria with no statistically significant difference (P>0.05). Three patients in the general anesthesia group and 7 patients in the local anesthesia group needed a reoperation. CONCLUSIONS: A microdiscectomy under local anesthesia shows faster recovery period. But it shows also a relative high revision rate. In patients with old age and underlying disease, local anesthesia can be used for the microdiscectomy selectively and careful exploration of the herniated disc is required.

Tumoral calcinosis is an uncommon disease, characterized by deposits of large, calcified soft tissue masses around major joints in children and young adults. The causes of the lesion have not yet been established, but are presumed an inborn error of metabolism of phosphorus. It has been recommanded medical treatment or surgical excision, but recurrence of the lesion is frequent. We report a case of young female patient who presented with tumoral calcinosis at the age of 10 years.

Journal of Korean Society of Spine Surgery 2005;12(4):281-288
STUDY DESIGN: This is a retrospective study. OBJECTIVES: We wanted to determine the effectiveness of performing transpedicular screw fixation in idiopathic scoliosis surgery by evaluating the radiological results. LITERATURE REVIEW SUMMARY: Deformity correction using pedicle screw fixation in scoliosis surgery is one of the most effective methods of treatment. However, the extent of correction and the complication rate are quite variable. MATERIALS AND METHODS: We evaluated the radiological results of performing posterior correction with using transpedicular screws in sixty patients who were suffering with idiopathic scoliosis. The follow-up duration was 39 months (range: 12 to 91 months). The changes of the coronal and sagittal geometry in the major and compensatory curves were measured according to the Cobb method with using the anteroposterior and lateral radiographs in the standing and lateral bending positions before the surgery and at the final follow-up. RESULTS: In the coronal plane, the average correction rate of the major curve was 77% and that of the compensatory curve was 72% on the immediate postoperative radiographs. In the sagittal plane, the Cobb angle in those patients who had a hypokyphosis under 15 degrees was improved from 9.0 degrees to 21.2 degrees. The angle between the lowest instrumented vertebra and T10, and also the lumbar lordosis did not change significantly. The correction rate of the rotational deformity of the apical vertebra was 55%, and that of the translation degree was 68%. The correction rate of the translation of the lowest instrumented vertebra was 54% and that of the tilting angle was 77%. No patients had a significant loss of correction in the coronal or sagittal plane at the latest follow-up. CONCLUSIONS: Posterior correction using transpedicular screws was an effective method for treating idiopathic scoliosis, and it resulted in a high correction rate at the major curve and the compensatory curve even with short segment fixation, and it reduced the loss of the correction angle.

PURPOSE: The purpose of this study was to examine the effects of a cognitive behavioral stress management program on diabetic self-care and glycemic control with type 2 diabetic patients. METHODS: Thirty three diabetic patients who were older than 40 were recruited from a public health center and conveniently assigned into both experimental(n=16) and control groups(n=17). Participants in the experimental group had attended the weekly cognitive behavioral program for 8 weeks. Data were collected from June 2005 to August 2006 and analyzed by independent t-test using the SPSS WIN program. RESULTS: After an 8 week intervention, participants in the experimental group reported on increasement of diabetic self-care behaviors and an increasement of blood glucose levels, which were significantly different from those in the control group. CONCLUSION: On the basis of those findings, we concluded that the cognitive behavioral stress management program has positive effects on diabetic self-care and glycemic control for the patients with DM. Further research is needed to identify the long-term effects of the cognitive behavioral program.

Journal of Korean Society of Spine Surgery 2000;7(2):264-270
STUDY DESIGN: A retrospective study OBJECTIVES: To demonstrate the early experience of operative treatment about adjacent segments degeneration after lumbar fusion. SUMMARY OF LITERATURE REVIEW: The treatment of degenerative changes at adjacent segment after lumbar spinal fusion have not been well described in literature. MATERIALS AND METHODS: A retrospective reviews of radiographs, medical records and follow up study were undertaken in eight patients who had been treated surgically due to degenerative changes at adjacent segment after lumbar fusion. Average follow up duration was 25 months. Causes of secondary operation were 3 cases of segmental instability, 2 cases of degenerative spondylolisthesis, 2 cases of degenerative spinal stenosis, 2 cases of cauda equina syndrome, 1 case of disc degeneration. Clinical results were evaluated by using of author's criteria. For the radiographic evaluation, plain roentgenogram(AP, Lat. flextion/extension Lat.), CT, MRI were checked. RESULTS: The mean time interval to secondary operation from first operation was seven years nine months. At the preoperative CT or MRI film review, there were initial adjacent segment degenerative changes in half of the cases preoperatively. The level developing degenerative changes were upper segment in 5 cases, lower segment in 2 cases and both segment in 1 case. Most common segment was L3,4 in 5 cases. The second operations were mainly PLIF in 7 cases and PL fusion in 1 case. All cases showed solid fusion. Clinical results were excellent in 3 cases, good in 4 cases, fair in 1 case and poor in no case. CONCLUSION: The early clinical and radiographic results of surgical treatment was satisfactory. If the degenerative changes of adjacent segments are detected preoperatively, there are some needs to consider the extension of surgery according to the severity of the lesions. We think that the results of secondary operation was better in case of PLIF than posterolateral fusion because PLIF provided more rigid stability which enabled early walking stability and better corrective power. But long term results of that should be followed up.

Journal of Korean Society of Spine Surgery 2016;23(2):93-99
STUDY DESIGN: Retrospective study. OBJECTIVES: To evaluate the clinical and radiological outcomes of posterior interbody fusion using pedicle screw fixation after posterior decompression for high-grade spondylolisthesis. SUMMARY OF LITERATURE REVIEW: The surgical treatment of high-grade spondylolisthesis has been controversial. However, few reports on the results of reduction and posterior interbody fusion after posterior decompression have been published. MATERIALS AND METHODS: Thirteen patients with L5-S1 high-grade spondylolisthesis (Meyerding grade III, IV) who underwent reduction and posterior interbody fusion were analyzed with at least 2 years of follow-up. The mean age of the patients (male 2, female 11) was 51 years. Classified by the type of spondylolisthesis, 10 cases were isthmic, 2 cases dysplastic, and 1 case degenerative. A visual analogue scale (VAS), the Oswestry Disability Index (ODI) score, bone union, anterior slippage, and slip angle were used in comparing clinical and radiographic outcomes. RESULTS: All cases showed improvement of preoperative symptoms. The VAS and ODI score improved from a mean of 8.9 points and 36.2 points preoperatively to 2.1 points and 10.2 points, respectively, at last follow-up. The degree of anterior slippage measured by Taillard's method was improved from a mean of 57.7% before surgery to mean of 14.6% at last follow-up. The slip angle also changed from a mean of 2.4° kyphosis before surgery to a mean of 7.6°C lordosis at last follow-up. There were two complications: infection and new radiating pain. CONCLUSIONS: Reduction and posterior interbody fusion using pedicle screw fixation after posterior decompression was a useful surgical method for high-grade spondylolisthesis that corrected lumbosacral kyphosis, filled the structural space of the anterior column, and acheived fusion of interbody movement.

Journal of Korean Society of Spine Surgery 2002;9(4):322-331
PURPOSE: To compare clinical results and radiologic changes after arthroscopic and microscopic discectomy of lumbar disc herniation in teenagers who have no degenerative change. MATERIALS AND METHODS: From Jan 1990 to Aug 2001. 70 lumbar disc herniations were performed in patients below 20 years old who were admitted to our department, among these 67 cases (49:male, 18:female) were evaluated for at least 1 year. Their aver-age age was 18.1 years (13 ~20 years). Forty-six received microscopic discectomy and 21 arthroscopic discectomy. Mean follow-up duration was 26.4 months (12 ~88 months). RESULTS: Clinical results and disc height change were compared between the arthroscopic and microscopic discectomy groups using the criteria of MacNab, and the relationship between disc height change and clinical results, excised disc volume, opera-tive technique, body mass index and symptom duration were investigated. Clinically there was no significant difference between the two groups (p=0.425), and their results were the same as those of adults. At the 1 year-follow up, disc height changes showed no correlation with the method of operation (p=0.996) or the volume of the excised disc. Postoperative disc height in teenagers of lumbar disc herniation who showed no degenerative change significantly decreased with time, but no significant relation was observed between disc height changes and clinical results, operative technique, excised disc volume, body mass index, involved disc site or symptom duration between the two groups. CONCLUSION: We believe that arthroscopic discectomy is an effective method, if the patients status permits, because it has the advantages of non-invasiveness, short hospitalization period and earlier return to normal life.

Journal of Korean Society of Spine Surgery 2017;24(4):231-235
STUDY DESIGN: Retrospective study. OBJECTIVES: To evaluate the efficacy of cervical expansive laminoplasty for patients with quadriplegia due to traumatic cervical spinal cord injury (SCI) without skeletal injury. SUMMARY OF LITERATURE REVIEW: There are a few studies on the surgical results for acute cervical SCI without bony injury. MATERIALS AND METHODS: From 2003 to 2010, among the patients who visited emergency room with post-traumatic quadriplegia, 12 patients who had underwent cervical expansive laminoplasty for acute cervical SCI without body injury and cord compression on MR images were included in this study. We evaluate the pre-operative swelling on MRI, the change of neurologic symptoms at pre-, post operative state, respiration state, complication and survival period. RESULTS: The average of motor index scores at the time of admission to the emergency room was 23 (4–30), and the average was changed to 29(4–43) during the follow-up period. No significant neurological improvement was observed in 11 cases except 1 case. The average time for operation after the injury was 26 hours(9–72). 4 patients showed paradoxical respiration when they first visited emergency room and the symptom continued after the operation and during follow-up periods. Another 4 patients showed paradoxical respiration after the operation. In all 8 cases who showed paradoxical respiration, tracheostomy and occasional ventilation were needed. In the follow-up period, 6 patients died due to respiratory failure within 1 year after the surgery. All these patients presented severe spinal cord edema on preoperative MRI with paradoxical respiration. CONCLUSIONS: Efficacy of expansive laminoplasty for quadriplegic patients due to acute cervical SCI without bony injury may be limited. In many patients, no significant neurological recovery was observed but it was clearly identified that prognosis was related to the grades of spinal cord edema and paradoxical respiration.
