The palpation of spinous process and transverse process of vertebra are important part of the assesment and treatment from Orthopedic manual therapy. But the palpation area is descriptive differently each of literatures. So we generally got these outcomes. : There are C2, C3, C4 and C6 process as a bony landmarks and these are important part of establish the precise location of pain appears from cervical spine. Even though C7 process regard a prominent part, it is hard to distinguish C6 and process of T1. Thru that differentiation, grab the patient's forehead and try them cervical and hyper-extension check any movement of process or put on the fingers on C7 preocess and check the movement. The palpation of thoracic spine process is the land mark which determines general level orientation in the spine easily, there are T2, T7 spinous process. However, It is depends on how do you test the patient's arm when you palpate it and it can effect on spinous process. The transverse process of C1 is the only spot for palpation in cervical spine, and T1-3, T12 transverse process can palpate it when it stands on the process. The end of T4-6, T11 is placed on middle on vertebra of transverse process and transverse process. T7-9, T10 transverse process is place on same position as spinous process which is upper part of the spine.

Although several artificial disc designs have been developed for the treatment of discogenic low back pain and used clinically, biomechanical change with its implantation seldom studied. To evaluate the effect of artificial disc implantation on the biomechanics of lumbar spinal unit, nonlinear three-dimensional finite element model of L1-L5, S1 was developed and strain and stress of vertebral body and surrounding spinal ligaments were predicted. Intact osteoligamentous L1-L5, S1 model was created with 1-mm CT scan of a volunteer and known material property of each element were applied. This model also includes the effect of local muscles which was modeled with pre-strained spring elements. The intact model was validated with reported biomechanical data. Two models implanted with artificial discs, SB Charite or Prodisc, at L4/5 via anterior approach were also developed. The implanted model predictions were compared with that of intact model. Angular motion of vertebral body, force on spinal ligaments, facet joint contact force with $2\sim12$ Nm flexion-extension moment.

Most extracranial schwannomas are solitary, but neurofibromas are frequently associated with other manietations of neurofibromatosis. Schwannomas that occur within the context of neurofibromatosis tend to be multiple, but multiple schwannomas without manifestation of neurofibromatosis type 2 are very rare. The authors report a very rare case of multiple spinal intradural schwannomas in the absence of neurofibromatosis Type 2 maniestations. A 40-year-old man suffered from longstanding low back pain and left side sciatica which was treated with two stage operations. MRI showed multiple intradural mass lesions extending from L1 vertebral segment to S1 vertebral segment. There were no clinical and radiological manifestations of Type 2 neurofibromatosis. Histologically confirmed diagnosis was schwannoma.

We describe a case of a 71-year-old male patient who experienced progressive bilateral proximal upper limb weakness and atrophy without sensory symptoms and signs over 5 years. Electromyography demonstrated denervation potentials and neuropathic motor unit action potentials on C5-C7 myotome muscles bilaterally. Cervical spine magnetic resonance imaging revealed engorged anterior epidural venous plexus, T2 hyperintensity localized to grey matter ("snake-eye" appearance) at C2-C6 vertebral level, and ventral epidural fluid collection from C6 to T8 vertebral level. This case indicates that bibrachial amyotrophy associated with epidural fluid leak should be suspected in patients presenting with progressive bilateral upper limb weakness and atrophy without sensory involvement.

Radiographic left atrial dimension (RLAD) is a useful measurement to assess left atrial enlargement in dogs. There are studies on the use of RLAD on various breeds of dogs, but no study on a specific breed with myxomatous mitral valve disease (MMVD). This study was conducted to compare RLAD measurements in Maltese dogs with MMVD ACVIM stage B1 and B2, and also to investigate the correlation of RLAD with the LA:Ao ratio. A total of 29 Maltese dogs were the subjects of this study. Each dog was diagnosed with MMVD ACVIM stage B1 or B2 based on physical examination, thoracic radiography, and echocardiography. The vertebral heart size (VHS), RLAD, LVIDDn, and LA:Ao ratio were measured and compared to evaluate the differences. There were significant differences in the RLAD, LVIDDn, and LA:Ao ratio between dogs with MMVD ACVIM stage B1 and those with stage B2. There was a significant correlation between the LA:Ao ratio and both the RLAD and VHS measurements, but the correlation coefficient was higher for RLAD. The RLAD scores exhibited a significant difference between dogs with ACVIM Stage B1 and with those with B2, and these scores had a higher correlation with the LA:Ao ratio measured by echocardiography than with VHS.

Objectives: This long-term case report presents the case of an ovarian cancer patient with brain, cervical lymph node, and vertebral metastasis suppressed by traditional Korean medicine in combination with cytokine-induced killer (CIK) cell-based immunotherapy. Methods: The patient received acupuncture, moxibustion, GunChil-go, Hangam-dan, and CIK cell-based immunotherapy. The Eastern Cooperative Oncology Group and tumor markers were used to evaluate the treatment effects. Results: Integrative cancer treatment suppressed the progression of cancer, and the patient achieved eight-year survival. The performance status improved, and the tumor marker level was maintained. Conclusions: We suggest that an integrative cancer treatment that includes traditional Korean medicine can be a meaningful treatment option for advanced ovarian cancer.

The azygos vein can be formed as a single root, two roots, and three roots, namely lateral, intermediate and the medial roots respectively. The hemiazygos vein and the accessory hemiazygos vein are the tributaries of azygos vein rather than its left side equivalents. Its variations, especially in young persons without any relevant risk factors, may result in thromboembolic illness. This study aimed to describe the morphological and morphometric variations of azygos system of veins. The present study was conducted on thirty formalin fixed adult human cadavers by dissecting azygos vein from formation to termination and variations were noted. The azygos vein was formed by a single root in 56.7%, by two roots: the lateral root and intermediate root in 36.7% cases and by the lateral root and medial root in 6.6%. The vertebral level of termination of azygos vein was seen at the level of T4 vertebrae in 70% cases, at the level of T3 vertebrae in 20% of cases and at the level of T5 vertebrae in 10% cases. The course of azygos vein was varying in 13.3%. These morphological variations can be useful while performing mediastinal surgery, mediastinoscopy, surgery of the deformations of the vertebral column, neurovascular surgeries of the retroperitoneal organs, disc herniation and fracture of thoracic vertebrae.

The posterior inferior cerebellar artery (PICA) is often involved in pathologies of the posterior cranial fossa. Therefore, a good understanding of the vessel's normal and variant courses is important to the neurosurgeon or neurointerventionalist. During the routine microdissection of the craniocervical junction, an unusual arrangement between the highest denticulate ligament and PICA was observed. On the right side, the PICA was given rise to by the V4 segment of the vertebral artery 9 mm after the artery entered the dura mater of the posterior cranial fossa. The artery made an acute turn around the lateral edge of the highest denticulate ligament to then recur 180 degrees and travel medially toward the brainstem. Invasive procedures that target the PICA should be aware of the variant as described herein.

본 연구에서는 의료 영상과 유한요소 해석을 이용하여 골절된 척추체의 치료를 위해 골 시멘트를 주입하는 추체 성형술(vertebroplasty)에 영향을 미치는 여러 인자들에 대해 생체 역학적으로 분석하여 평가하고자 하였다. 의료 영상을 통해 구현된 모델들은 분석하고자 하는 인자에 대하여 크게 단분절과 다분절 유한요소 모델의 2 가지 형태로 구분하였다. 단분절 유한요소 모델을 통해 골다공증의 정도, 주입된 골 시멘트의 양, 골 시멘트의 주입량 및 환자에게 주입된 골 시멘트 양의 적절성을 평가하였으며, 골 시멘트의 주입이 척추체의 구조적 안정성에 미치는 효과를 분석하기 위하여 척추체 상종판에 수직 압축하중을 가하여 이때의 최대 수진 변위량을 분석하였다. 또한 단분절 척추체의 강성도(stiffness) 값을 산출한 뒤, 정상 상태의 척추체의 강성도 값으로 정규화 하였다. 다분절 유한요소 모델의 경우, 압박 골절 상태를 적용하여 척추 만곡의 변화가 인체에 미치는 영향을 분석하기 위하여 골절의 정도를 3 가지로 구현하였으며, 모델의 최상부에 압축 하중을 가한 후의 척추 만곡의 변화 정도를 분석하였다. 추체 성형술에 대한 다양한 인자들에 대한 분석 결과, 추체 성형술을 통해 환자의 골밀도가 상대적으로 높은 경우(BMD 50mg/$m\ell$이상)와 환자의 척추체 망상골 부피의 약 15%에 해당하는 골 시멘트 주입 시 가장 큰 척추체의 구조적 안정성의 증가 효과를 가져올 것으로 예측되었다. 또한 척추 골절이 미치는 영향에 대한 분석 결과, -2.8$^{\circ}$의 정상적인 후만곡을 가지는 T12∼L2 운동 분절이 골절의 모델링 후 약 9∼17$^{\circ}$의 큰 전만곡을 가지게 되었으며 이러한 척추 만곡의 변화는 동일한 하중 하에서 급격한 척추 만곡의 변화를 야기하는 것으로 나타났다. 또한 골절의 정도가 심할수록 척추 변형은 더욱 크게 증가하는 것으로 나타났다. 이러한 연구 결과들로부터, 전반적으로 추체 성형술은 골 시멘트의 주입량 또는 골밀도에 상관없이 약화된 척추체의 자체의 구조적 안정성의 증가 효과를 가져왔으며 골절로 인해 추체의 높이가 손상되었을 경우 이를 회복하는 것이 중요한 인자의 하나임을 나타내는 결과로 사료되어진다.
