RÉSUMÉ

Purpose@#This study examined the effect of lag screw insertion on proximal fragments by separating the right and left sides of intertrochanteric fractures in elderly patients that underwent intramedullary nailing. @*Materials and Methods@#Patients aged ≥65 years that underwent intramedullary nailing after a diag-nosis of intertrochanteric fractures during the period February 2012 to May 2016 were included in the study. The subjects were divided into right and left side groups. The effect of the clockwise rotational force generated when a lag screw was inserted on the proximal fragment was evaluated in both groups. @*Results@#In the right and left groups, most proximal fragments were located in the intramedullary canal after surgery (45 cases [75.0%] and 67 cases [73.6%], respectively). Clockwise rotation due to lag screw placement in the right group occurred in two cases (3.3%), which both showed internal rotation, and in four cases (4.4%) in the left group, all of which showed external rotation. @*Conclusion@#After intramedullary nailing of intertrochanteric fractures in elderly patients, proximal fragments were mostly located in the intramedullary cavity. The results obtained confirmed that the clockwise rotational force generated by lag screw insertion did not affect left or right sides.

RÉSUMÉ

A 67-year-old male patient with a history of epididymectomy and anti-tuberculosis treatment for epididymis tuberculosis was admitted for acute low back pain and radiating pain. The patient had no history of gout but showed hyperuricemia and a bone destruction lesion in the facet joint and lamina of the lumbar spine. A histology examination was performed after a computed tomography-guided needle biopsy, and the findings were compatible with gout spondyloarthropathy and tuberculous spondylitis. The acute symptoms improved after conservative treatment for gouty arthritis. When patients with hyperuricemia risk factors, such as taking anti-tuberculosis drugs, complain of acute low back pain, gout spondyloarthropathy should be considered in a differential diagnosis.

RÉSUMÉ

Purpose@#This study examined the effects of the postoperative administration of parathyroid hormone (PTH) on fracture healing in intertrochanteric fractures accompanied by osteoporosis in elderly females. @*Materials and Methods@#Female patients aged 65 years and more who underwent surgery after a diagnosis of intertrochanteric fractures and osteoporosis during the period from July 2013 to December 2017 were included as subjects. The subjects were divided into two groups: PTH-treated group and non-PTH-treated group. The formation time of the first callus, timing of the bridging callus, and time of bony union for both groups were evaluated. @*Results@#In the PTH-treated group, the mean time of the first callus formation, average time of bridging callus, and the average time of bony union were 32, 58, 83 days, respectively, which were significantly shorter than that of the untreated group. @*Conclusion@#PTH, a treatment for osteoporosis, promotes callus formation and the healing process. Therefore it will be helpful in intertrochanteric fractures accompanied by osteoporosis in elderly females.

RÉSUMÉ

Background@#To compare the risk of low back pain (LBP) and related spinal diseases between smokers (exposure group) and nonsmokers (non-exposure group). No large registry study has so far investigated the association between smoking and LBP-related spinal diseases such as intervertebral disc disease, spinal stenosis, spinal instability, and spondylolisthesis. @*Methods@#A random sample was taken from the Korean National Health Insurance Research Database. In total, 204,066 men (160,105 smokers, 43,961 nonsmokers) who were followed up between 2002 and 2013 were included in the analysis. Patients with previous back pain or spinal disease in 2003 and 2004, patients with inappropriate data, and women (due to the lower percentage of smokers) were excluded. The Cox proportional hazard model was used to investigate the risk of LBP and related spinal diseases associated with smoking, while adjusting for demographic, clinical, and socioeconomic factors. @*Results@#The overall median follow-up period was 5.6 years (interquartile range, 3.48–8.43 years). Compared to the nonsmoker group, the smoker group had a higher incidence of LBP (p = 0.01), intervertebral disc disease (p < 0.001), spinal stenosis (p = 0.004), spinal instability (p < 0.001), and spondylolisthesis (p = 0.023). Compared to the nonsmoker group, the smoker group had a higher adjusted hazard ratio (HR) per year of LBP (HR, 1.18; 95% confidence interval [CI], 1.15 to 1.21), intervertebral disc disease (HR, 1.25; 95% CI, 1.21 to 1.30), spinal stenosis (HR, 1.52; 95% CI, 1.41 to 1.64), spinal instability (HR, 1.33; 95% CI, 1.24 to 1.44), and spondylolisthesis (HR, 1.49; 95% CI, 1.23 to 1.80). @*Conclusions@#Smokers in male samples were at higher risk for LBP and related spinal diseases than nonsmokers.

RÉSUMÉ

Nociceptin/orphanin FQ (N/OFQ) and its receptor, nociceptin opioid peptide (NOP) receptor, are localized in brain areas implicated in depression including the amygdala, bed nucleus of the stria terminalis, habenula, and monoaminergic nuclei in the brain stem. N/OFQ inhibits neuronal excitability of monoaminergic neurons and monoamine release from their terminals by activation of G protein-coupled inwardly rectifying K⁺ channels and inhibition of voltage sensitive calcium channels, respectively. Therefore, NOP receptor antagonists have been proposed as a potential antidepressant. Indeed, mounting evidence shows that NOP receptor antagonists have antidepressant-like effects in various preclinical animal models of depression, and recent clinical studies again confirmed the idea that blockade of NOP receptor signaling could provide a novel strategy for the treatment of depression. In this review, we describe the pharmacological effects of N/OFQ in relation to depression and explore the possible mechanism of NOP receptor antagonists as potential antidepressants.

RÉSUMÉ

PURPOSE: To evaluate the efficacy of minimally invasive spinal fusion in comparison to open fusion for adult lumbar spondylolisthesis or spondylosis. MATERIALS AND METHODS: The present study was conducted as a meta-analysis of all estimates from studies that were selected after comprehensive literature search by two independent reviewers. RESULTS: Of 745 articles, nine prospective cohort studies were identifed. The quality of evidence was downgraded because of study design, inconsistency, imprecision, and publication bias. Greater Oswestry Disability Index score improvement [weighted mean difference (WMD), 3.2; 95% confdence interval (CI), 1.5 to 5.0; p=0.0003] and a lower infection rate (odds ratio, 0.3; 95% CI, 0.1 to 0.9; p=0.02) were observed in the minimally invasive group (low-quality evidence). The minimally invasive group had less blood loss (WMD, 269.5 mL; 95% CI, 246.2 to 292.9 mL; p < 0.0001), a shorter hospital stay (WMD, 1.3 days; 95% CI, 1.1 to 1.5 days, p < 0.0001), and longer operation time (WMD, 21.0 minutes; 95% CI, 15.9 to 26.2 minutes; p < 0.0001) and radiation exposure time(WMD, 25.4 seconds; 95% CI, 22.0 to 28.8 seconds, p < 0.0001) than the open group (low-quality evidence). There were no significant differences in pain improvement, fusion rate, complications, or subsequent surgeries between the two treatment groups (lowquality evidence). CONCLUSION: Although present findings are limited by insufficient evidence and there is a lack of adequately powered high-quality randomized controlled trials to address this gap in evidence, our results support that minimally invasive lumbar fusion is more effective than open fusion for adult spondylolisthesis and other spondylosis in terms of functional improvement, reducing infection rate, and decreasing blood loss and hospital stay.

RÉSUMÉ

STUDY DESIGN: A case report. OBJECTIVES: To report and discuss an extremely uncommon cause of lumbar plexopathy seat belt injury. SUMMARY OF LITERATURE REVIEW: For patients who undergo traffic accidents, most cases of seat belt injury cause trauma to the lower torso. Seat belt injury is associated with variable clinical problems such as vascular injury, intestinal injury (perforation), vertebral injury (flexion-distraction injury), chest wall injury, diaphragmatic rupture/hernia, bladder rupture, lumbosacral plexopathy, and other related conditions. MATERIALS AND METHODS: A 38-year-old male truck driver (traffic accident victim) who suffered monoplegia of his right leg due to lumbar plexus injury without spinal column involvement. Injury to a lumbar plexus and the internal vasculatures originated from direct compression to internal abdominal organs (the iliopsoas muscle and internal vasculatures anterior to the lumbar vertebrae) caused by the seat belt. We have illustrated an extremely uncommon cause of a neurologic deficit from a traffic accident through this case. RESULTS: Under the impression of traumatic lumbar plexopathy, we managed it conservatively, and the patient showed signs of recovery from neurologic deficit. CONCLUSIONS: We need to review the lumbar plexus pathway, in patients with atypical motor weakness and sensory loss of the lower extremities which are not unaccompanied by demonstrable spinal lesions. Therefore, close history taking, physical examination and comprehension of injury mechanism are important in the diagnosis.

RÉSUMÉ

Atypical femoral fracture related to a long-term bisphosphonate therapy has commonly been reported; however, a fracture at the site other than the femur has rarely been reported to date. Herein, we report a case of a patient on long-term bisphosphonate therapy who presented atypical tibial insufficiency fracture at the anterolateral aspect of diaphysis, without trauma. We, for the first time in Korea, present this case with a literature review.

RÉSUMÉ

STUDY DESIGN: Literature review. OBJECTIVES: The aim of this study was to demonstrate surgical strategies for successful minimally invasive transforaminal lumbar interbody fusion (TLIF). SUMMARY OF LITERATURE REVIEW: Although many studies have reported the benefits and disadvantages of minimally invasive TLIF, few have described surgical strategies to improve the success rate or to reduce complications. MATERIALS AND METHODS: We searched for studies reporting the clinical and radiological outcomes of minimally invasive TLIF, and analyzed the optimal indications, technical pitfalls, and tips for successful surgical outcomes. RESULTS: The ideal candidate for minimally invasive TLIF is a patient with single or 2-level low-grade adult degenerative or isthmic spondylolisthesis. Incomplete decompression, dura tearing, nerve root injury, and implant-related complications were found to be the most commonly reported adverse events, especially in the early periods of a surgeon's experience. Precise positioning for skin incision and tube insertion, complete neural decompression, proper interbody preparation for bone graft and cage insertion, and the correct placement of percutaneous pedicle screws are critical strategies for successful surgical outcomes. Fully understanding the surgical pitfalls and tips described in this review is also important to avoid potential complications. CONCLUSIONS: It is imperative not only to carry out a comprehensive preoperative evaluation and proper patient selection, but also to perform meticulous surgical procedures with thoughtful considerations of potential pitfalls, in order to improve the success rate and to reduce the complications of minimally invasive TLIF.

RÉSUMÉ

BACKGROUND: As surgical complications tend to occur more frequently in the beginning stages of a surgeon's career, knowledge of perioperative complications is important to perform a safe procedure, especially if the surgeon is a novice. We sought to identify and describe perioperative complications and their management in connection with minimally invasive transforaminal lumbar interbody fusion (TLIF). METHODS: We performed a retrospective chart review of our first 124 patients who underwent minimally invasive TLIF. The primary outcome measure was adverse events during the perioperative period, including neurovascular injury, implant-related complications, and wound infection. Pseudarthroses and adjacent segment pathologies were not included in this review. Adverse events that were not specifically related to spinal surgery and did not affect recovery were also excluded. RESULTS: Perioperative complications occurred in 9% of patients (11/124); including three cases of temporary postoperative neuralgia, two deep wound infections, two pedicle screw misplacements, two cage migrations, one dural tear, and one grafted bone extrusion. No neurologic deficits were reported. Eight complications occurred in the first one-third of the series and only 3 complications occurred in the last two-thirds of the series. Additional surgeries were performed in 6% of patients (7/124); including four reoperations (two for cage migrations, one for a misplaced screw, and one for an extruded graft bone fragment) and three hardware removals (one for a misplaced screw and two for infected cages). CONCLUSIONS: We found perioperative complications occurred more often in the early period of a surgeon's experience with minimally invasive TLIF. Implant-related complications were common and successfully managed by additional surgeries in this series. We suggest greater caution should be exercised to avoid the potential complications, especially when surgeon is a novice to this procedure.

RÉSUMÉ

A 31-year-old male presented with severe back pain and paraparesis. Imaging studies demonstrated an extraosseous, extradural mass without bone invasion at the T11-T12 vertebral level, located dorsal to the thecal sac. The spinal cord was compressed ventrally. The lesion was completely excised after a T11-T12 laminectomy. Histopathological examination revealed a cavernous hemangioma. The patient's symptoms improved after excision of the lesion.

RÉSUMÉ

Partial or complete absence of the posterior arch of the atlas is a well-documented anomaly but a relatively rare condition. This condition is usually asymptomatic so most are diagnosed incidentally. There have been a few documented cases of congenital defects of the posterior arch of the atlas combined with atlantoaxial subluxation. We report a very rare case of congenital anomaly of the atlas combined with atlantoaxial subluxation, that can be misdiagnosed as posterior arch fracture.

RÉSUMÉ

PURPOSE: To identify cataract awareness in the Korean population. METHODS: The present study included 3,662 subjects who were diagnosed with a cataract by ophthalmic examination out of 11,058 subjects in the fourth Korea National Health and Nutrition Examination Survey (KNHANES IV). Among the 3,662 participants, 944 were aware that they already had a cataract. The socio-demographic disparities in cataract awareness were identified using multivariate analysis. RESULTS: The mean age of the study population was 65.6 years (standard deviation, 0.2). The awareness calculated based on total weighted population was 24.6% in people over 19 years of age (95% confidence interval, 22.5-26.6%). In multivariate logistic analysis, subjects with higher income, living in a rural area, having a spouse, and binge alcohol use were less likely to be aware of their cataract. In multivariate linear regression analysis after adjusting for confounding factors, there were statistically significant differences of mean in age and monthly house income. Deajeon (11%), and Gwangju (16%) were the lower ranked regions for cataract awareness in Korea. CONCLUSIONS: The cataract awareness in Korea was lower than in other developed countries. Public education and strategies to improve cataract awareness in susceptible people are necessary. More effort is needed to improve cataract awareness based on the Korean society's acceptance of ophthalmologists as in other countries.

RÉSUMÉ

STUDY DESIGN: Case report. OBJECTIVES: We report a very rare case of the inferior accessory ossicle of the anterior arch of the atlas misdiagnosed as anterior arch fracture. SUMMARY OF LITERATURE REVIEW: It is necessary to know the existence of inferior accessory ossicle of the anterior arch of the atlas, even though it is extremely rare. MATERIALS AND METHODS: A 29-year-old woman was referred to our emergency service unit with symptoms of neck pain and scalp laceration, after being involved in a car accident. She was diagnosed as the inferior accessory ossicle of the anterior arch of the atlas, by multiple diagnostic mordalities. RESULTS: The symptom of neck pain was relieved spontaneously, and her symptom has been relieved at her latest visit, as a follow up within 3 months. CONCLUSIONS: It is important to be aware of cervical anatomical variants because we commonly confuse it with other pathologic conditions, such as a fracture and thus, misdiagnose the condition.

RÉSUMÉ

STUDY DESIGN: This is a retrospective case study. PURPOSE: This study was designed to analyze the surgical outcomes of patients who underwent minimally invasive transforaminal lumbar interbody fusion (TLIF) for the treatment of spondylolisthesis and degenerative segmental instability. OVERVIEW OF LITERATURE: If the surgical outcomes of a procedure are evaluated together with multiple indications, it is not clear how the procedure helped each subgroup of patients. For the reason that some indications achieve better outcomes than the others, we performed a subgroup analysis using validated outcome measures to demonstrate the optimal indications and the treatment results of TLIF. METHODS: We conducted subgroup analyses by comparing the prospectively collecting data from the consecutive patients who underwent single-level minimally invasive TLIF for the treatment of the following 3 subgroups of indications: 23 cases of low-grade spondylolytic spondylolisthesis, 24 cases of degenerative spondylolisthesis, and 19 cases of degenerative segmental instability. RESULTS: The average duration of follow up was 36.1 +/- 9.9 months (range, 24 to 63 months). The preoperative pain and disability scores were significantly improved at final postoperative follow-up in all the subgroups (all measurements: p < 0.0001). The 3 subgroups exhibited an equivalent improvement of the pain and disability scores at the final follow-up. The rates of radiographic solid fusion and complications were also similar among the 3 groups. CONCLUSIONS: Our data suggests that minimally invasive TLIF optimally and equivalently alleviates all of the associated symptoms and disabilities from low-grade spondylolisthesis and degenerative segmental instability. Furthermore, these patients seem to have optimal surgical indications for minimally invasive TLIF, while maintaining favorable surgical outcomes.

RÉSUMÉ

An intradural extramedullary metastasis to the spinal nerve root across dura mater is extremely rare. The authors encountered a case 39-year-old man who suffered radiculopathy arising from a soft mass around nerve root mimicking a nerve sheath tumor compressing the 4th lumbar nerve root in the right intervertebral foramen between the 4th and 5th lumbar spine. After an excisional biopsy, the metastatic infiltration of adenocarcinoma was confirmed pathologically. The primary lesion was found to be an intrahepatic cholangiocarcinoma with multiple metastases. This report suggests that an intradural metastatic tumor can show similar clinical and radiographic findings to other disease,s such as a nerve sheath tumor. The results also suggest that proper diagnosis and further treatment are possible only by pathological confirmation after and excisional biopsy.

RÉSUMÉ

Intrapelvic pin migration of the Kirschner wires or the Steinman pins that are used for the treatment of hip fracture is rare, but it can be serious when it occurs. We experienced a delayed intestinal injury that was caused by the migration of an intrapelvic pin, and this happened 10 years after performing fixation for an acetabular fracture. For preventing this potential complication, the pins have to be used only as a temporary fixation and the end of the pins should be bent. Further, the patients should be followed up clinically and radiographically for a long time. If pin migration does occur, the pin should be removed.

RÉSUMÉ

PURPOSE: To compare the short-term clinical results of mini-midvatus minimally invasive total knee arthroplasty(TKA) with quadriceps-sparing minimally invasive TKA. MATERIALS AND METHODS: Between August 2005 and February 2006, 23 bilateral (46 knees) minimally invasive total knee arthroplasties were performed simultaneously using quadriceps-sparing surgical technique at one side and mini- midvastus minimally invasive technique at the contralateral side. The same surgeon performed all the operations with the same type of prosthesis(Nexgen LPS-flex Total Knee System) using MIS quadriceps-sparing instrument. The pos- toperative clinical and radiological results were analyzed in each group. RESULTS: There were no significant differences between the two groups in the operating time, total blood loss, length of skin incision, radiological results and postoperative HSS scores at 8 weeks and 1 year follow-up(p>0.05). Also, there were no differences in the postoperative range of motion and pain score assessed by visual analog scale at 1 day, 3 days, 7 days, 14 days, 8 weeks and 1 year follow-up(p>0.05). Conclusions: Compared to quadriceps-sparing TKA, mini-midvastus minimally invasive TKA revealed no significant differences in the short-term clinical and radiological results. Therefore, it can be considered as an effective, alternative minimally invasive technique.

RÉSUMÉ

PURPOSE: To compare the the clinical and radiographic results of the two approaches for posterior lumbar fusion, one-level posterior lumbar interbody fusion (PLIF) performed with a minimally invasive approach or the traditional open approach. MATERIALS AND METHODS: This study examined a consecutive series of 46 patients who underwent one-level PLIF procedure (27 cases performed with minimally invasive approach and 19 cases with traditional open approach) by one surgeon at one hospital. The following data were compared with a minimum 1-year follow-up: the clinical and radiographic results, surgical time, estimated blood loss, transfusion requirements, postoperative back pain, time needed before ambulation, length of hospital stay, and complications. RESULTS: There was no statistical difference between the two groups in terms of the clinical and radiographic results at the last follow-up. The minimally invasive group was found to have a less blood loss, fewer transfusion requirements, less postoperative back pain, a shorter recovery time, and a shorter hospital stay. However, minimally invasive group required a longer surgical time and there were 2 cases with technical complications. CONCLUSION: This study confirmed the favorable results reported by previous uncontrolled cohort studies. It also showed that the minimally invasive approach had a similar surgical efficacy to that of traditional open approach. However, minimally invasive technique requires a steep learning curve and attention in order to lower the risk of complications.
