A retrospective study.To investigate the relationship between trunk muscle cross-sectional area (MCSA) and fusion rate after posterior lumbar interbody fusion using pedicle screw fixation (PLIF-PSF).Although trunk muscles of the lumbar spine contribute to spinal stability and alignment, effect of trunk muscles on spinal fusion rate and time to fusion is unclear.A total of 192 adult patients with degenerative lumbar disease who underwent PLIF-PSF at L3-L4 or L4-L5 were included. The MCSA of the flexor (psoas major, PS), extensor (erector spinae, ES; multifidus, MF) were measured using preoperative lumbar magnetic resonance imaging at 3 segments. Bone union was evaluated using lumbar dynamic plain radiography. Patients were divided into 2 groups according to the presence of bone fusion.Most PS MCSAs in the fusion group were significantly larger than in the nonfusion group, except for MCSA at the L2-L3 segment (all P<0.05). In cases of ES and MF MCSAs, 4 of 6 segments were significantly large. Multivariate analysis revealed that the PS MCSA at L4-L5 was an independent factor for decreased possibility of nonfusion status in both segments (OR=0.812, P=0.028). Pearson analysis demonstrated that the most trunk MCSAs were negatively correlated with time to fusion for both segments and PS MCSAs exhibited a significant correlation with time to fusion except for MCSA at the L2-L3 segment.Trunk MCSAs were significantly larger for a fusion group than a nonfusion group. As trunk MCSAs increased, fusion timing decreased.
Bullet injuries to the spine may cause injury to the anatomical structures with or without neurologic deterioration. Most bullet injuries are acute, resulting from direct injury. However, in rare cases, delayed injury may occur, resulting in claudication. We report a case of intradural bullet at the L3-4 level with radiculopathy in a 30-year-old male. After surgical removal, radicular and claudicating pain were improved significantly, and motor power of the right leg also improved. We report the case of intradural bullet, which resulted in delayed radiculopathy.
Objectives: Objectives: In this study, we define a medical service type that combines Western medicine, Korean medicine, and complementary and alternative medicine (CAM) as an integrated medical service. This study, as part of tertiary hospital-based integrated medical service model and clinical field application, aims to collect status and opinions on integrated medical service for medical staff in the field.Methods: This is a survey study, and was conducted on doctors from Kyung Hee University Hospital and Korean medicine doctors from Kyung Hee University Korean Medicine Hospital. Respondents were recruited on a first-come, first-served basis until the number of respondents reached 120. The investigation was conducted for a total of 16 days from October 4, 2021 to October 19, 2021 by e-mail.Results: Recognition of integrated medical services was confirmed to be 45.8%, and 49.2% responded positively to the necessity of it. As a group of diseases that require the establishment of integrated medical services in the future, 'disorders of musculoskeletal systems and connective tissues' was the highest. The most expected advantages of providing integrated medical services were 'increased satisfaction of patients and guardians' and 'increased treatment effects.’Conclusions: In this study, we investigated the perception of doctors and Korean medicine doctors on integrated medical services that combine Western medicine, Korean medicine, and CAM. It has been confirmed that medical staff generally have a positive perception of integrated medical services, and if the scientific basis for the effect of integrated medical services is supported, the rate of positive perception is expected to increase.
Percutaneous epidural neuroplasty (PEN) is a known interventional technique for the management of spinal pain. As with any procedures, PEN is associated with complications ranging from mild to more serious ones. We present a case of intracranial subdural hematoma after PEN requiring surgical evacuation. We review the relevant literature and discuss possible complications of PEN and patholophysiology of intracranial subdural hematoma after PEN.
Objectives: Currently, Korea’s medical services are divided into Western medicine and Korean medicine, and people who are not satisfied with the existing treatments are looking for complementary and alternative medicine(CAM). Therefore, this study attempted to confirm patients' perception of the ongoing collaborative treatment and integrated medical service that added CAM to collaborative treatment based on tertiary hospital users. So that we can confirm the expected advantage and disadvantage of integrated medical service system and the necessity of supporting medical expenses for it.Methods: The survey was conducted on 100 people who experienced tertiary hospital treatment and other 100 people who experienced both tertiary hospital treatment and Korean medicine treatment at the same period. The survey was conducted until the number of respondents in both group reached 100. The survey was conducted through e-mail and was conducted from September 27, 2021 to October 8, 2021.Results: For the advantages of collaborative treatment ‘increased in psychological stability,’ and for disadvantages ‘longer time spent for treatment’ were the most common. If integrated medical services are implemented in the future, expected advantages include ‘consideration of various treatments.’ and expected disadvantages include ‘increased medical cost.’ The needs to expand support for health insurance for integrated medical services were 75.5% among responders.Conclusions: We were able to find out the (expected) advantages and disadvantages of the collaborative medical care and the integrated medical system that medical users experienced or expected, also confirmed positive answers to the expansion of health insurance support for the integrated medical system.
Cause of pituitary apoplexy has been known as hemorrhage, hemorrhagic infarction or infarction of pituitary adenoma or adjacent tissues of pituitary gland.However, pituitary apoplexy caused by pure infarction of pituitary adenoma has been rarely reported.Here, we present the two cases pituitary apoplexies caused by pituitary adenoma infarction that were confirmed by transsphenoidal approach (TSA) and pathologic reports.Pathologic report of first case revealed total tumor infarction of a nonfunctioning pituitary macroadenoma and second case partial tumor infarction of ACTH secreting pituitary macroadenoma.Patients with pituitary apoplexy which was caused by pituitary adenoma infarction unrelated to hemorrhage or hemorrhagic infarction showed good response to TSA treatment.Further study on the predisposing factors of pituitary apoplexy and the mechanism of infarction in pituitary adenoma is necessary.10.
The purpose of this study was to provide anatomical data on the dimensions and location of the subaxial transverse foramen (TF) in relation to surgical landmarks routinely used during anterior cervical procedures.A total of 116 patients who underwent preoperative computed tomography (CT) evaluations for degenerative cervical disease were enrolled. Axial and coronal CT images of the cervical vertebrae from C3 to C6 were analyzed to measure interforaminal distance, the TF distance from the anterior and posterior vertebral body margin, TF dimensions, and the TF medial margin from the tip and medial margin of the uncus. Comparative and correlative analyses were also performed according to age, body mass index (BMI), and sex.All measurement values in male patients were larger than those in their female counterparts. The interforaminal distance gradually increased from C3 to C6. The distance of the TF medial margin from the tip of the uncus was found be above approximately 3 mm in all vertebrae except C6. Correlation analysis revealed that age had a significant negative relationship with the transverse diameter of TF. In contrast, BMI had a significant positive correlation with interforaminal distance. Moreover, the distances of the TF medial margin from the tip and medial margin of the uncus showed strong negative correlations with age.Useful morphometric data were obtained that may help the operating surgeon to avoid vertebral artery injury. The safe distance from the tip of the uncus to the TF medial margin was found to be approximately 3 mm, and this distance should not be violated during lateral decompression. In addition, this value may decrease with age.
