Purpose: To Analyze the exit site of pin inserted at the anterior glenoid rim in the reconstruction of the Bankart lesion and SLAP lesion using transglenoid suture technique. Materials and Methods: In the twenty adult right cadeveric scapula, insertions of pin were performed using guide at the position of 1, 2, 3 O'clock of glenoid rim. We measured the exit site of dorsal surface of the scapula by medial distance from sagittal plane of lateral border of scapular spine and the vertical distance from posterior border of the scapular spine. Results: When the pin was inserted caudally within 10 degree, at the position of 1, 2, 3 O'clock, the medial distance from lateral border of the scapula is averaged 29.4, 19.2, 34.0 mm respectively and the vertical distance from posterior border of the scapular spine is averaged 15.0, 18.6, 17.2 mm respectively. When the pin was inserted caudally within 20-30 degree, the medial distance is averaged 14.6, 14.2, 15.8 mm respectively and the vertical distance is averaged 31.6, 31.9, 32.1 mm respectively. Conclusion: When the pin was inserted caudally within ten degrees using the guide, the pin exit appeared at the more medial side of the base of scapular spine and the more inferior of scapular spine. This can make the firm suture tied over scapular spine during repair SLAP and the Bankart lesion, and also prevent the injury of suprascapular nerve.

Study Design: A case study. Purpose: To assess the chronological changes of the disease-related kyphosis after chemotherapy alone, secondly to clarify the role of growth cartilage in the healed lesion on kyphosis change, and to define the accurate prediction time in assessing residual kyphosis. Overview of Literature: None of the previous papers up to now dealt with the residual kyphosis, stability and remodeling processes of the affected segments. Methods: One hundred and one spinal tuberculosis children with various stages of disease processes, age 2 to 15 years, were the subject materials, between 1971 to 2010. They were treated with two different chemotherapy formula: before 1975, 18 months of triple chemotherapy (isoniazid [INH], para-aminosalicylic acid, streptomycin); and since 1976, 12 months triple chemotherapy (INH, rifampicin, ethambutol, or pyrazinamide). The first assessment at post-chemotherapy one year and at the final discharge time from the follow-up (36 months at minimum and 20 years at maximum) were analyzed by utilizing the images effect of the remaining growth plate cartilage on chronological changes of kyphosis after initiation of chemotherapy. Results: Complete disc destruction at the initial examination were observed in two (5.0%) out of 40 cervical spine, eight (26.7%) out of 30 dorsal spine, and six (19.4%) out of 31 lumbosacral spine. In all those cases residual kyphosis developed inevitably. In the remainders the discs were partially preserved or remained intact. Among 101 children kyphosis was maintained without change in 20 (19.8%), while kyphosis decreased in 14 children (13.7%), and increased in 67 children (66.3%) with non-recoverably damaged growth plate, respectively. Conclusions: It could tentatively be possible to predict the deformity progress or non-progress and spontaneous correction at the time of initial treatment, but it predictive accuracy was low. Therefore, assessment of the trend of kyphotic change is recommended at the end of chemotherapy. In children with progressive curve change, the deformity assessment should be continued till the maturity.

Intracranial hypotension syndrome typically occurs spontaneously or iatrogenically. It can be associated with headache, drowsy mentality and intracranial heamorrhage, Iatrogenic intracranial hypotension can occur due to dural pucture, trauma and spine surgery. Treatment may include conservative therapy and operation. We report a case of a 54-year-old man who was successfully treated with epidural blood patches for intracranial hypotension due to cerebrospinal fluid (CSF) leakage into the lumbosacral area after spine surgery.

The purpose of this case report is to describe a rare case of a cervicothoracic spinal epidural hematoma (SEH) after anterior cervical spine surgery. A 60-year-old man complained of severe neck and arm pain 4 hours after anterior cervical discectomy and fusion at the C5-6 level. Magnetic resonance imaging revealed a postoperative SEH extending from C1 to T4. Direct hemostasis and drainage of loculated hematoma at the C5-6 level completely improved the patient's condition. When a patient complains of severe neck and/or arm pain after anterior cervical spinal surgery, though rare, the possibility of a postoperative SEH extending to non-decompressed, adjacent levels should be considered as with our case.

Objective : It is challenging to make solid fusion by posterior screw fixation and laminectomy with posterolateral fusion (PLF) in thoracic and thoracolumbar (TL) diseases. In this study, we report our experience and follow-up results with a new surgical technique entitled posterior thoracic cage interbody fusion (PTCIF) for thoracic and TL spine in comparison with conventional PLF. Methods : After institutional review board approval, a total of 57 patients who underwent PTCIF (n=30) and conventional PLF (n=27) for decompression and fusion in thoracic and TL spine between 2004 and 2019 were analyzed. Clinical outcomes and radiological parameters, including bone fusion, regional Cobb angle, and proximal junctional Cobb angle, were evaluated. Results : In PTCIF and conventional PLF, the mean age was 61.2 and 58.2 years (p=0.46), and the numbers of levels fused were 2.8 and 3.1 (p=0.46), respectively. Every patient showed functional improvement except one case of PTCIF. Postoperative hematoma as a perioperative complication occurred in one and three cases, respectively. The mean difference in the regional Cobb angle immediately after surgery compared with that of the last follow-up was 1.4° in PTCIF and 7.6° in conventional PLF (p=0.003), respectively. The mean durations of postoperative follow-up were 35.6 months in PTCIF and 37.3 months in conventional PLF (p=0.86). Conclusion : PTCIF is an effective fusion method in decompression and fixation surgery with good clinical outcomes for various spinal diseases in the thoracic and TL spine. It provides more stable bone fusion than conventional PLF by anterior column support.

Vertebral artery injury is a rare complication of anterior cervical approach. We report two patients who suffered injury to vertebral artery during anterior cervical spine surgery. The mechanism of injury, their operative management, and the subsequent outcome were assessed and relevant literatures reviewed. The awareness of the possibility of vertebral artery injury is most important to prevent and it's occurrence is best avoided by a thorough understanding of the anatomical relationships of the artery, the spinal canal, and the vertebral body and careful use of surgical instruments.

Transforaminal lumbar interbody fusion (TLIF) is commonly used procedure for spinal fusion. However, there are no reports describing anterior cage dislodgement after surgery. This report is a rare case of anterior dislodgement of fusion cage after TLIF for the treatment of isthmic spondylolisthesis with lumbosacral transitional vertebra (LSTV). A 51-year-old man underwent TLIF at L4-5 with posterior instrumentation for the treatment of grade 1 isthmic spondylolisthesis with LSTV. At 7 weeks postoperatively, imaging studies demonstrated that banana-shaped cage migrated anteriorly and anterolisthesis recurred at the index level with pseudoarthrosis. The cage was removed and exchanged by new cage through anterior approach, and screws were replaced with larger size ones and cement augmentation was added. At postoperative 2 days of revision surgery, computed tomography (CT) showed fracture on lateral pedicle and body wall of L5 vertebra. He underwent surgery again for paraspinal decompression at L4-5 and extension of instrumentation to S1 vertebra. His back and leg pains improved significantly after final revision surgery and symptom relief was maintained during follow-up period. At 6 months follow-up, CT images showed solid fusion at L4-5 level. Careful cage selection for TLIF must be done for treatment of spondylolisthesis accompanied with deformed LSTV, especially when reduction will be attempted. Banana-shaped cage should be positioned anteriorly, but anterior dislodgement of cage and reduction failure may occur in case of a highly unstable spine. Revision surgery for the treatment of an anteriorly dislodged cage may be effectively performed using an anterior approach.

Background: Local anesthetic infiltration at the site of a surgical wound is commonly used to control postoperative pain. In this study, we examined the effectiveness of continuous local infiltration at an abdominal surgical site in patients undergoing anterior lumbar interbody fusion (ALIF) surgery. Methods: Sixty-one patients who underwent ALIF surgery were enrolled. For thirtyone of them, a continuous local anesthetics infiltration system was used at the abdominal site. We collected data regarding the patients' sleep quality; satisfaction with pain control after surgery; abilities to perform physical tasks and the additional application of opioids in the postoperative 48 hours. Results: The On-Q system group showed reduced visual analogue scale scores for pain at the surgical site during rest and movement at 0, 12, 24, and 48 hours; and more was satisfied with pain control management at the first postoperative day (7.0 ± 1.2 vs. 6.0 ± 1.4; P = 0.003) and week (8.1 ± 1.6 vs. 7.0 ± 1.8; P = 0.010) than the control group. The number of additional patient-controlled analgesia (PCA) bolus and pethidine injections was lower in the On-Q group (PCA: 3.67 ± 1.35 vs. 4.60 ± 1.88; P = 0.049 and pethidine: 2.09 ± 1.07 vs. 2.73 ± 1.38; P = 0.032). Patients who used the On-Q system performed more diverse activity and achieved earlier ambulation than those in the control group. Conclusions: Continuous wound infiltration with ropivacaine using an On-Q system may be effective for controlling postoperative pain after ALIF surgery.

Background: The purpose of this study is to analyze the current status and factors of elderly patients' hospitalization for hip replacement, knee replacement, and general spine surgery. Methods: National health insurance data in 2018 was provided by the National Health Insurance Service. We used multiple regression to analyze factors associated with the medical utilization of hip replacement, knee replacement, and general spine surgery in elderly patients over 65 years old. The dependent variables are the length of stay and total health expenditure. The independent variables are the demographic-social factors (sex, age, region, insurance type, income level) and surgery-related factors (institution type, location of the hospital, surgery classification). Results: The most common factor affecting surgery was the location of medical institutions. Compared with the medical institutions located in metropolitan, the length of stay in rural medical institutions was higher and total health expenditure was lower. The lower quartile of income, the higher the length of stay and total health expenditure. In addition, the variables of age, type of health insurance, and type of medical institution were statistically significant. Conclusion: In this study, we confirmed the effect of sociodemographic factors and medical institution factors on the Healthcare Utilization of spinal and joint surgery.

Objective : The anterior approach to the cervical spine now selves as the surgical across of choice for cervical spine disease. Vocal cord paryalysis(VCP) follow the procedure as a complication, and it is most common complication of this procedure. However, the frequency and etiology of this injury are not clearly defined. This study was performed to establish the clinical features of vocal cord paralysis in anterior cervical spine surgery(ACSS). Material and Method : Retrospectively, medical records of patients who underwent ACSS at Hallym university medical center, Hangang Sacred Heart Hospital between January 2000 and March 2006 were reviewed. Further detailed review of the patients with documented VCP after surgery was then performed. Results : 242 ACSSs were performed and 9 patients with VCP were identified (3.71%) In 9 patients with VCP, 8 patients had right-sided approaches (6.01%) and 1 patient had left-sided approach (0.91%). All 9 patients had VCP on ipsilateral side and 8 patients were recovered completely on follow up period. Duration of ACSS, multilevel exposure and low-level (below the C6 level) exposure have been found to be associated with higher risk. Conclusion : For avoiding the recurrent laryngeal nerve injury, surgeon have to understand the clinical features of VCP in ACSS. As right-sided approach has a greater risk of recurrent laryngeal nerve injury, we suggest that the left-sided approach be given more consideration.
