background: radiographic examination of tmj is indicated when there are clinical signs of pathological conditions, mainly bone changes that may influence the diagnosis and treatment planning. the purpose of this study was to evaluate and to compare the validity and diagnostic accuracy of uncorrected and corrected sagittal tomographic images in the detection of simulated mandibular condyle erosi...

BACKGROUND Fixed sagittal imbalance (a syndrome in which the patient is only able to stand with the weight-bearing line in front of the sacrum) has many etiologies. The most commonly reported technique for correction is the Smith-Petersen osteotomy. Few reports on pedicle subtraction procedures (resection of the posterior elements, pedicles, and vertebral body through a posterior approach) are ...

STUDY DESIGN Prospective radiographic study. OBJECTIVE To investigate the feasibility of controlling quality of reconstructed sagittal balance for sagittal imbalance. SUMMARY OF BACKGROUND DATA Patients with sagittal imbalance cannot walk or stand erect without overwork of musculature because of compromised biomechanical advantage. The result is muscle fatigue and activity-related pain. Dur...

We performed sagittal splitting osteotomy using fresh, unfixed cadavers. Observation was carried out macroscopically and with light microscopy and 3-dimensionally reconstructed images. The aim of this study was to clarify the relationship between the fracture line and the Haversian canal and Haversian lamellae. Macroscopic observation revealed that the fracture line run through the mandibular a...

Intradural extra-arachnoid lumbar disc herniation is a rare disease. Few MRI findings have been reported. We experienced an intradural extra-arachnoid lumbar disc herniation. We reviewed the preoperative MRI findings. Lumbar spine T2-weighted sagittal MRI showed that one line of the ventral dura was divided into two by a disc herniation. We speculated that the two lines comprised the dura and a...

The aim of the current study was to test whether or not proprioceptive errors (biases) are associated with visual memory performance, and to distinguish which movement types are more important in this relationship. The study included 63 pupils with normal vision, including 49 pupils from a conventional school and 14 pupils from a school for slower children. We used the Proprioceptive Diagnosis ...

STUDY DESIGN Cross-sectional study. PURPOSE The purpose of this study was to evaluate a novel landmark for the cervical pedicle screw insertion point. OVERVIEW OF LITERATURE To improve the accuracy of pedicle screw placement, several studies have employed the lateral mass, lateral vertical notch, and/or inferior articular process as landmarks; however, we often encounter patients in whom we...

Objective
 Lip position has become one of the most important soft tissue analyses as it influences occlusion, tooth stability and facial aesthetic. Hence, objective this study was to compare short-term long-term sagittal lip positions/changes using Burstone line (B-line).
 
 Methods
 The sample consisted 18 Caucasoid females only (14 extractions, 4 non-extractions) who were ...

BACKGROUND Little evidence exists regarding how prosthesis design characteristics affect performance in tasks that challenge mediolateral balance such as turning. This study assesses the influence of prosthetic foot stiffness on amputee walking mechanics and balance control during a continuous turning task. METHODS Three-dimensional kinematic and kinetic data were collected from eight unilate...
