Objective : To investigate the radiographic characteristics of the uppermost instrumented vertebrae (UIV) and UIV+1 compression fractures that are predictive of revision surgery following long-segment spinal fixation. Methods : A total 27 patients who presented newly developed compression fracture at UIV, UIV+1 after long segment spinal fixation (minimum 5 vertebral bodies, lowest instrumented vertebra of L5 or distal) were reviewed retrospectively. Patients were divided into two groups according to following management : revisional surgery (group A, n=13) and conservative care (group B, n=14). Pre- and postoperative images, and images taken shortly before and after the occurrence of fracture were evaluated for radiologic characteristics Results : Despite similar degrees of surgical correction of deformity, the fate of the two groups with proximal junctional compression fractures differed. Immediately after the fracture, the decrement of adjacent disc height in group A (32.3±7.6 mm to 23.7±8.4 mm, Δ=8.5±6.9 mm) was greater than group B (31.0±13.9 mm to 30.1±15.5 mm, Δ=0.9±2.9 mm, p=0.003). Pre-operative magnetic resonance imaging indicated that group A patients have a higher grade of disc degeneration adjacent to fractured vertebrae compared to group B (modified Pfirrmann grade, group A : 6.10±0.99, group B : 4.08±0.90, p=0.004). Binary logistic regression analysis indicated that decrement of disc height was the only associated risk factor for future revision surgery (odds ratio, 1.891; 95% confidence interval, 1.121-3.190; p=0.017). Conclusion : Proximal junctional vertebral compression fractures with greater early-stage decrement of adjacent disc height were associated with increased risk of future neurological deterioration and necessity of revision. The condition of adjacent disc degeneration should be considered regarding severity and revision rate of proximal junctional kyphosis/proximal junction failures.

Objectives This study aims to find out effect of Korean medicine treatment on managing thoracolumbar compression fractures through retrospective observational study. Methods Among hospitalized patients at the Department of Korean Medicine Rehabilitation from January 1st, 2018 to February 28th, 2023, a total of 24 inpatients who were diagnosed with thoracolumbar compression fractures and received Korean medicine treatment were included in this study. Numeric rating scale (NRS) was used for pain assessment and clinical variables such as sex, symptoms, age, thoracolumbar injury classification and severity (TLICS) scores were collected. For subgroup analysis to analyze factors affecting treatment response, we divided patients into responders and non-responders according to NRS change. For statistical analysis, we compared before/after hospitalization and analyzed distinct features between two groups. Results Most of the patients were in their 70s and 83.33% were female. Average hospitalization period was 24.54±11.91 days. All patients had back pain as their chief complaint and only 2 patients received surgeries. In TLICS, only 1 patient got score 6, which represented surgery indication. After Korean medicine treatment, NRS of almost every patient got lower significantly at the time of discharge (3.02±1.93) than admission (5.52±1.95). Comparing two groups, responders had lower NRS at the time of discharge and TLICS score of them were lower than non-responders. Conclusions Our results show that Korean medicine treatment for thoracolumbar compression fractures was effective in reducing pain. There were distinct clinical features such as age, past history, surgeries between those with significant improvement in pain scores and those who did not.

Objective : Percutaneous vertebroplasty is often complicated by the presence of multiple fractures or non-localizing pain in the patients with osteoporotic vertebral fractures. The purpose of this study is to estimate the value of preoperative radiologic studies in the localization of symptomatic vertebrae and to determine the factors which can influence on the clinical results. Materials and Methods : We retrospectively reviewed the clinical and radiologic data of 57 vertebrae in 30 patients underwent percutaneous vertebroplasty for osteoporotic vertebral compression fractures. Inclusion criteria was severe pain(McGill-Melzack score 3, 4 or 5) associated with the acute vertebral fractures and absence of spinal nerve root or cord compression sign. Acute symptomatic vertebral fracture was determined by the presence of signal change on MR images or increased uptake on whole body bone scan. Results : Pain improvement was obtained immediately in all patients and favorable result was sustained in 26 patients(86.7%) during the mean follow-up duration of 4.7 months(5 complete pain relief, 21 marked pain relief). Those who underwent vertebroplasty for all acute symptomatic vertebrae had significantly better clinical result than those who did not. Further vertebral collapse and eventual bursting fracture occurred in 1 vertebra which showed intradiskal leakage of bone cement and disruption of cortical endplate on postoperative CT scan. Conclusion : Preoperative MR imaging and whole body bone scan are very useful in determining the symptomatic vertebrae, especially in the patients with multiple osteoporotic vertebral fractures. To obtain favorable clinical result, the careful radiologic evaluation as well as clinical assessment is required. Control of PMMA volume seems to be the most critical point for avoiding complications.

Purpose: The purpose of this study is to evaluate the effectiveness and indications of the modified Essex-Lopresti reduction in calcaneal fractures. Materials and Methods: We reviewed retrospectively 41 cases of displaced intraarticular calcaneal fractures. The fracture was reduced with Essex-Lopresti technique with modification in compression of the lateral wall with the specially designed compression device instead of the operator's hands. We evaluated the results of treatment by AOFAS scale and the radiographic parameters including the Bohler's angle, calcaneal width, calcaneofibular distance and the congruency of the posterior facet. Results: Boler's angle was restored from 11 to 29.6 degrees on average, heel width was reduced to 112% of contralateral value, the calcaneofibular gap was restored up to 87.9% of contralateral side, and the articular surface of the posterior facet was restored less than 2 mm of step off and less than 2 mm of gap. AOFAS scale averaged 87 points. The quality of reduction was best in Sander's type II fractures. Small sized fragments in type III fractures could not be reduced. The results were better when the reductions were performed within 24 hours of injury. Conclusion: The modified Essex-Lopresti reduction was less invasive, easy to perform, and the results of treatment were similar to those of open reduction; it seemed to be a reasonable alternative for the selected intraarticular calcaneal fractures.

Purpose: Internal fixation using compression hip screws (CHS) and traction tables placing patients in the supine position is a gold standard option for treating intertrochanteric fractures; however, at our institution, we approach this treatment with patients in a lateral decubitus position. Here, the results of 100 consecutive elderly (i.e., ${\geq}45$ years of age) patients who underwent internal fixation with CHS in lateral decubitus position are analyzed. Materials and Methods: Between March 2009 and May 2011, 100 consecutive elderly patients who underwent internal fixation with CHS for femoral intertrochanteric fracture were retrospectively reviewed. Clinical outcomes (i.e., Koval score, Harris hip score [HHS]) and radiographic outcomes (i.e., bone union time, amount of sliding of lag screw, tip-apex distance [TAD]) were evaluated. Results: Clinical assessments revealed that the average postoperative Koval score decreased from 1.4 to 2.6 (range, 0-5; P<0.05); HHS was 85 (range, 72-90); and mean bone union time was 5.0 (range, 2.0-8.2) months. Radiographic assessments revealed that anteroposterior average TAD was 6.95 (range, 1.27-14.63) mm; lateral average TAD was 7.26 (range, 1.20-18.43) mm; total average TAD was 14.21 (range, 2.47-28.66) mm; average lag screw sliding was 4.63 (range, 0-44.81) mm; and average angulation was varus $0.72^{\circ}$(range, $-7.6^{\circ}-12.7^{\circ}$). There were no cases of screw tip migration or nonunion, however, there were four cases of excessive screw sliding and six cases of varus angulation at more than $5^{\circ}$. Conclusion: CHS fixation in lateral decubitus position provides favorable clinical and radiological outcomes. This technique is advisable for regular CHS fixation of intertrochanteric fractures.

Objective : The purpose of this retrospective clinical study was to describe a treatment for osteoporotic burst fracture in the setting of severe fractures involving fragmentation of the posterior wall and neural compromise with symptoms of cord compression. Methods : Indication for microscopic decompression and open kyphoplasty were intractable pain at the level of a known osteoporotic burst fractures involving neural compression or posterior wall fragmentation. A total of 18 patients [mean age, 74.6 years] with osteoporotic thoracolumbar burst fractures [3 males, 15 females] were included in this study. In all cases, microscopic decompressive laminectomy was followed by open kyphoplasty. Clinical outcome using VAS score and modified MacNab's grade was assessed on last clinical follow up [mean 6.7 months]. Radiological analysis of sagittal alignment was assessed preoperatively, immediately postoperatively, and at final follow up. Results : One level augmentation and 1.8 level microscopic decompression were performed. Mean blood loss was less than 100 ml and there were no major complications. The mean pain score before operation and at final follow up was 7.2 and 1.9, respectively. Fourteen of 18 patients were graded as excellent and good according to the modified MacNab's criteria. Overall, 6.0 degrees of sagittal correction was obtained at final follow-up. Conclusion : The combined thoracolumbar microscopic decompression and open kyphoplasty for severe osteoporotic fractures involving fragmentation of posterior wall and neural compromise provide direct visualization of neural elements, allowing safe cement augmentation of burst fractures. Decompressive surgery is possible and risk of epidural cement leakage is controlled intraoperatively.

Objective : To evaluate the effectiveness and long-term outcome predictors of percutaneous sacroplasty (PSP). Methods : This single-center study assessed 40 patients with sacral insufficiency fractures using the short-axis technique under C-arm flat-panel detector computed tomography (CT). Two radiologists reviewed the patients' magnetic resonance and CT images to obtain imaging findings before PSP and determine technical success, respectively. The short-term outcomes were visual analog scale score changes and opioid usage reductions. Long-term outcomes were determined using telephone interviews and the North American Spine Society (NASS) patient-satisfaction index at least one year after PSP. Results : Technical success was achieved without any significant complications in 39 patients (97.5%). Telephone interviews were possible with 12 patients and failed in 10 patients; death was confirmed in 18 patients. Fifteen patients (50%) re-visited the hospital and received conservative treatment, including spinal injections. Nine patients reported positive satisfaction (NASS patient-satisfaction index 1 or 2), while the negative satisfaction group (NASS patient-satisfaction index 3 or 4, n=3) showed a higher incidence of compression fractures at the thoracolumbar spine level (66.7% vs. 22.2%) and previous spinal injection history (66.7% vs. 33.3%). The poor response group also showed higher incidences of facet joint arthrosis (100% vs. 55.6%), central canal stenosis (100% vs. 22.2%), neural foraminal stenosis (33.3% vs. 22.2%), scoliosis (100% vs. 33.3%), and sagittal malalignment (100% vs. 44.4%). Conclusion : PSP was effective for sacral insufficiency fractures and showed good long-term outcomes. Combined compression fractures in the thoracolumbar spine and degenerative lumbar pathologies could be possible poor outcome predictors.

Background: Increased frequency of comminuted clavicle mid-shaft fractures and importance of functional satisfaction through early joint exercise has resulted in higher emphasis on surgical treatments. This study aimed to evaluate the clinical radiological results of treatment of clavicle mid-shaft fractures by open reduction and internal fixation using a plate with a small incision. Methods: The subjects of this study were 80 clavicle mid-shaft fracture cases treated with internal fixation using a plate from October 2010 to July 2014. Clavicle mid-shaft fractures were internally fixated using anatomical plates or locking compression plates. Achievement of bone union, union period, and clavicle length shortening were evaluated radiologically, and clinical assessment was done by using Constant and University of California at Los Angeles (UCLA) scores. Results: All 80 cases were confirmed to have achieved bone union through radiographs with an average union period of 10.9 weeks (range: 7-18 weeks). The average clavicle length of shortening in the affected side was 1.8 mm (range: 0-17 mm). The average UCLA score and Constant score were 33.6 (range: 25-35) and 92.5 (range: 65-100), respectively. Regarding complications, four cases reported skin irritation by metal plates, and one case reported a screw insertion site fracture due to minor trauma history. Conclusions: We were able to induce successful bone union and obtain clinically satisfactory results in displaced mid-shaft fractures of the clavicle without major complications such as nonunion through treatment of internal fixation using a plate.
