Objective : We performed a retrospective analysis of medical records and radiographic images of patients who never underwent spinal treatment including diagnosis. The objective of this study is to explain the biomechanical and physiologic characteristics of cervical alignment related to thoracic inlet angle including T1 slope changes in each individual. Methods : We reviewed the cervical CT radiographs of 80 patients who visited ENT outpatient clinic without any symptom, diagnosis and treatment of cervical spine from January 2011 to September 2012. All targeted people were randomized without any prejudice. We assessed the data-T1 slope, Cobb's angle C2-7, neck tilt, sagittal vertical axis (SVA) C2-7 and thoracic inlet angle by the CT radiographs. Results : The relationships between each value were analyzed and we concluded that Cobb's angle C2-7 gets higher as the T1 slope gets higher, while the SVA C2-7 value decreases. Conclusion : We propose that the T1 slope is background information in deciding how much angle can be made in the cervical spinal angle of surgical lordotic curvature, especially severe cervical deformity.

Objectives : The purpose of this study was to identify spinal curvatures, plantar pressure and foot angles in a walking. Methods : 19 outpatients under 19 years old were included. Plantar pressure and foot angle in a walking were measured by using Gaitview AFA-50. Spinal curvatures were measured by using radiograph. Results : The cervical lordotic angle is significantly difference with left and right plantar pressure(p=0.027). The thoracic kyphotic angle is significantly difference with left and right plantar pressure(p=0.026). Cobb's angle is significantly difference with left and right plantar pressure(p=0.027). The other plantar pressure were no difference from spinal curvatures and foot angle in a walking. Conclusion : There were no correlation between plantar pressure, spinal curvatures and foot angle. We consider that needed more additional study.

Objective : Cervical expansive laminoplasty is an effective surgical method to address multilevel cervical spinal stenosis. During surgery, the spinous processes of C2 and C7 are usually preserved to keep the insertion points of the cervical musculature and nuchal ligament intact. In this regard, dome-like laminectomy (undercutting of C7 lamina) instead of laminoplasty is performed on C7 in selected cases. However, resection of the lamina can weaken the C7 lamina, and stress fractures may occur, but this complication has not been characterized in the literature. The objective of the present study was to investigate the incidence and risk factors for C7 laminar fracture after C7 dome-like laminectomy and its impact on clinical and radiological outcomes. Methods : Patients who underwent cervical open-door laminoplasty combined with C7 dome-like laminectomy (n=123) were classified according to the presence of C7 laminar fracture. Clinical parameters (neck/arm pain score and neck disability index) and radiologic parameters (C2-7 angle, C2-7 sagittal vertical axis, and C7-T1 angle) were compared between the groups preoperatively and at postoperatively at 3, 6, 12, and 24 months. Risk factors for complications were evaluated, and a formula estimating C7 fracture risk was suggested. Results : C7 lamina fracture occurred in 32/123 (26%) patients and occurred at the bilateral isthmus in 29 patients and at the spinolaminar junction in three patients. All fractures appeared on X-ray within 3 months postoperatively, but patients did not present any neurological deterioration. The fracture spontaneously healed in 27/32 (84%) patients at 1 year and in 29/32 (91%) at 2 years. During follow-up, clinical outcomes were not significantly different between the groups. However, patients with C7 fractures showed a more lordotic C2-7 angle and kyphotic C7-T1 angle than patients without C7 fractures. C7 fracture was significantly associated with the extent of bone removal. By incorporating significant factors, the probability of C7 laminar fracture could be assessed with the formula 'Risk score = 1.08 × depth (%) + 1.03 × length (%, of the posterior height of C7 vertebral body)', and a cut-off value of 167.9% demonstrated a sensitivity of 90.3% and a specificity of 65.1% (area under the curve, 0.81). Conclusion : C7 laminar fracture can occur after C7 dome-like laminectomy when a substantial amount of lamina is resected. Although C7 fractures may not cause deleterious clinical outcomes, they can lead to an unharmonized cervical curvature. The chance of C7 fracture should be discussed in the shared decision-making process.

Objectives : The propose of this study is to analyze characteristics with sex, age, motivation, symptom, Impression, treatment effect about temporomandibular disorder patients. Method : We performed a retrospective study of 52 patients who visited the Jaseng Hospital of Oriental Medicine, from August 2008 to October 2008. Result : Women occupied the most part. And 27 persons in the 20th are the most distribution of age. The majority of patients occured the symptom for no reason. In the distribution of symptoms, TMD pain(88.46%), Click sound(82.69%), neck pain(52.92%), headache(38.46%), lumbago(21.15%) happened. In the impression through radiological diagnoses, The majority of patients diagnosed Straightening of cervical lordotic curvature. Oriental medical treatment showed a very valuable effect on improvement of TMD symptom. Conclusion : The results showed a valuable treatment effect of temporotandibular disorders on Oriental medical treatment. Therefore this work have the necessity of continuous study and observation and will help us to understand the features of patients who visiting the TMD clinic of Jaseng Hospital of Oriental medicine.
