STUDY DESIGN: Prospective, single-center study.PURPOSE: The current trend of operative treatment for adult spinal deformity (ASD) is combined anterior-posterior staged surgery. When anterior surgery was first performed, oblique lumbar interbody fusion (OLIF) was employed; this method became increasing popular. This study aimed to determine the lordosis correction that can be achieved using OLIF and assess whether we can preoperatively predict the lordosis correction angle achieved using OLIF.OVERVIEW OF LITERATURE: Many previous studies on OLIF have shown improved clinical and radiologic outcomes. With the increase in the popularity of OLIF, several surgeons have started using larger cages to attain greater lordosis correction. Moreover, some studies have reported complications of OLIF because of immoderate cage insertion. To our knowledge, this is the first prospective study that attempted to determine whether it is possible to predict the lordosis correction angle achieved with OLIF preoperatively, using fullextension lateral view (FELV).METHODS: Forty-six patients with ASD were enrolled. All the operations were performed by a single surgeon in two stages (first, anterior and second, posterior) with a 1-week interval. Radiological evaluation was performed by comparing the Cobb’s angle of the segmental and regional lordosis obtained using preoperative and postoperative simple radiography (including the FELV) and magnetic resonance imaging (MRI).RESULTS: Regional lordosis (L1–S1) in the whole-spine standing lateral radiograph was −3.03°; however, in the supine lateral MRI, it was 20.92°. The regional lordosis of whole-spine standing lateral and supine lateral (MRI) was significantly different. In the FELV, regional lordosis was 25.72° and that in the postoperative supine lateral (MRI) was 25.02°; these values were not significantly different.CONCLUSIONS: Although OLIF offers many advantages, it alone plays a limited role in ASD treatment. Lordosis correction using OLIF as well as lordosis determined in the FELV was possible. Hence, our results suggest that FELV can help predict the lordosis correction angle preoperatively and thus aid the selection of the appropriate technique in the second staged operation.

PURPOSE: To perform comparative analysis between the results of internal fixation and hemiarthroplasty in unstable intertrochanteric fracture of osteoporotic bone. MATERIALS AND METHODS: From February 2003 to February 2006, 36 patients treated surgically for unstable intertrochanteric fractures were evaluated. The patient's age was older than 70 year old; the T-score of preoperative bone mineral density (BMD) was lower than -3.0; they were followed up for more than 1 year. The patient were divided into two groups. One group was treated with dynamic hip screw or proximal femoral nail (Group A, 23 cases), and the other group was treated with bipolar hemiarthroplasty (Group B, 13 cases). The two groups were compared in terms of hip joint function using Clawson classification and radiologically. RESULTS: Nonunion and fixation failure happened in 6 cases (26%) of gruop A. However, all patients in group B showed stable maintenance of implant. Recovery of hip joint function was found in 13 cases (43%) of group A, whereas 12 cases (93%) of group B recovered. CONCLUSION: Nonunion and failure of fixation happened more frequently in internal fixation than bipolar hemiarthroplasty, and the postoperative hip joint function was better in bipolar hemiarthroplasty than internal fixation. Therefore, bipolar hemiarthroplasty might be better operative treatment for unstable intertrochanteric fracture of osteoporotic bone.

PURPOSE: To evaluate the functional changes, postop delirium and complications after cemented bipolar hemiarthroplasty for the femur neck fractures in patients aged around ninety. MATERIALS AND METHODS: Between May 1995 and April 2002, of the twenty seven patients, 17 who follow-up for at least one year were included in this study. Walking ability, activity of daily living, mental status, chronic illness, postoperative delirium and complications were evaluated retrospectively using Yoon's walking class, ADL scale, MMSE-K score, ASA classification, DSM IV respectively. RESULTS: The walking ability was decreased to 2.4 from 3.3 tendency of reliance in ADL scale was increased to 8.3 from 4.5, MMSE-K score was decreased to 15.9 from 21.7. There was no significant change in status of chronic illness. Postoperative delirium occurred in eight (47%) cases and all of them recovered completely. complications included bladder problem in eleven (66%) cases, temporary respiratory distress in two (12%) cases, hip dislocation in two (12%) cases, infection in one (6%) case. Overall thirteen (78%) cases were able to walk with supports. CONCLUSION: This study indicates that physicians treation femur neck fractures in patients aged around ninety must anticipate worsening of the functional changes more especially in regard to walking level, activity of daily living and mental status, little changes of chronic disease status, complete recovery of postop delirium and high complication rate

Pneumatosis intestinalis (PI) is a rare condition that is characterized by multiple subserosal and submucosal gas-filled areas in the bowel wall. Gastric pneumatosis describes the presence of gas within the stomach wall. This is caused by a disruption in gastric mucosa leading to the dissection of air into the wall. The extract cause of PI is still unknown; however, it may be associated with coexisting disease. Gastric PI has been rarely documented. So, we report on a 75-year-old man with acute gastric pneumatosis following his palliative chemotherapy. He underwent 3rd cycle of gemcitabine and erlotinib 3 weeks prior to admission. The treatment was started with nasogastric tube insertion and parenteral nutrition. Then, gastric pneumatosis was improved. However, the patient was died because of worsening underline disease and general condition. We suggest that chemotherapy should be considered the case of pneumatosis and careful X-ray interpretation will be necessary for detecting the pneumatosis earlier.

OBJECTIVES: The purpose of this study was to assess the effect of sagittal spino-pelvic alignment on the clinical symptoms of thoracolumbar kyphosis (TLK; T10-L2 Cobb's angle >20°) in osteoporotic patients.SUMMARY OF LITERATURE REVIEW: Few studies have investigated the clinical symptoms and radiological features of TLK caused by degenerative changes. There is also controversy over whether clinical symptoms will deteriorate in patients with TLK or which treatment should be chosen according to the degree of TLK. MATERIALS AND METHODS: From May 2005 to May 2016, we reviewed 75 patients who were diagnosed with TLK (T10-L2 Cobb's angle >20°) and osteoporosis. Patients were excluded from the study if they had neurological symptoms, underlying spinal disorders, or unstable vertebral fractures. Fifty patients with TLK due to an osteoporotic vertebral compression fracture (group F) and 25 patients with senile TLK (group S) were assessed by clinical symptoms and radiological parameters. Thoracolumbar kyphosis angle and sagittal vertical axis (SVA) were also analyzed. Clinical symptoms were assessed using a visual analogue scale (VAS) and the Oswestry Disability Index (ODI). RESULTS: There were no significant differences in clinical symptoms (VAS, ODI) and radiological parameters between groups F and S, or according to the degree of TLK(20°–30°, 30°–40°, >40°). Clinical symptoms were significantly more severe in patients with sagittal imbalance (SVA >5 cm) than in those with sagittal balance. CONCLUSIONS Sagittal imbalance is a more important factor affecting clinical symptoms than the cause or the degree of TLK. Therefore, sagittal imbalance should be considered in the management of TLK in osteoporotic patients.

STUDY DESIGN: Retrospective study. PURPOSE: Associations among risk factors related to adjacent segmental disease (ASD) remain unclear. We evaluated the risk factors and segmental lordosis ratio to prevent ASD developing after lumbar spinal fusion. OVERVIEW OF LITERATURE: Risk factors related to ASD development are age, sex, obesity, pre-existing degeneration, number of fusion segments, and decreased postoperative lumbar lordosis (LL). However, the associations among these factors are still unclear and should be clearly identified. METHODS: We retrospectively reviewed data on 274 patients who underwent lumbar spinal fusion of three segments or below for lumbar degenerative disease from January 2010 to December 2012, with over 5 years of follow-up. Patients with preoperative sagittal vertical axis (SVA) >5 cm were excluded due to sagittal imbalance. A total of 37 patients with ASD and 40 control patients (CTRL) were randomly selected in a similar distribution of matching variables: age, sex, and preoperative degenerative changes. Sex, age, number of fusion segments, radiologic measurements, L4–5–S1/L1–S1 LL ratio, and spinopelvic parameters (pelvic incidence [PI], pelvic tilt [PT], sacral slope [SS], and SVA) were analyzed. Logistic regression was used to analyze the correlation between PI–LL mismatch and L4–5–S1 segmental lordosis rate. RESULTS: No significant difference was found between ASDs and CTRL groups regarding age, sex, number of fusion segments, fusion method, and preoperative and postoperative spinopelvic parameters (PI, SS, PT, and LL). However, regarding the L4–5–S1/L1–S1 lordosis ratio, 50% (p=0.045), 60% (p=0.031), 70% (p=0.042), 80% (p=0.023), and 90% (p=0.023) were statistically significant; <20% (p=0.478), 30% (p=0.223), and 40% (p=0.089) were not statistically significant. In the postoperative PI–LL <10 group, ASD occurred less frequently than in the PI–LL >10 group, and the difference was statistically significant (p=0.048). CONCLUSIONS: Patients with a postoperative L4–5–S1/L1–S1 lordosis ratio >50% had less occurrence of ASD. Correcting LL according to PI and physiologic segmental lordosis ratio is important in preventing ASD.

STUDY DESIGN: Retrospective, single-center study. PURPOSE: We aimed to determine the perioperative complications of oblique lumbar interbody fusion (OLIF) as a first-stage procedure in combined anterior and posterior operation for adult spinal deformity (ASD) along with sagittal imbalance. Specifically, we aimed to identify the radiological and clinical types of perioperative surgical complications and the factors affecting these complications. OVERVIEW OF LITERATURE: OLIF has recently gained popularity, and there are several reports of good outcomes and only a few of complications with OLIF; however, a few studies have focused on the perioperative surgical complications of ASD along with sagittal imbalance. METHODS: The perioperative period was a 1-week interval between the anterior and posterior procedures. All patients underwent simple radiography and magnetic resonance imaging preoperatively and postoperatively. Cage placement was evaluated for displacement (i.e., subsidence and migration) and vertebral body fracture. Clinical patient complaints were evaluated perioperatively. Student t-test was used for data analysis. RESULTS: A total of 46 patients were included, totaling 138 fusion segments. A week after OLIF, 14 patients/33 segments (30.4%/23.9%) demonstrated endplate injury-associated cage placement change. Subsidence was the most common cage placement-related complication. As compared with patients without endplate injury, those with endplate injuries showed significantly larger correction angles and a higher proportion of them had larger height cages than the disk height in the full-extension lateral view. Although 32.6% of the patients experienced perioperative clinical complications, they were relatively minor and transient. The most common complication was severe postoperative pain (Visual Analog Scale score of >7), and hip flexor weakness spontaneously resolved within 1 week. CONCLUSIONS: OLIF yielded more than expected endplate injuries from treatment modalities for ASD along with sagittal imbalance. Therefore, surgeons should be cautious about endplate injury during OLIF procedures. It is difficult to accomplish lordosis correction via OLIF alone; therefore, surgeons should not attempt this impractical correction goal and insert an immoderate cage.
