background: malocclusion, as a worldwide issue, can cause a lot of problems for patients. panoramic (pr) and lateral cephalometric (lcr) radiographs are both usually indicated for orthodontic treatments. the aim of this study was to analyze vertical and sagittal parameters of both jaws on prs and to compare them on lcrs. materials and methods: in this cross sectional study, 61 samples from all ...

abstract study design . a retrospective radiographic review was undertaken in patients treated for ais. objectives. to determine the most important preoperative factors that affect on postoperative junctional kyphosis complication. methods sagittal spine profilewere measured on the standing radiographs before, after and in the last follow-up visit of the operated patients for ais. the following...

Background: In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment ofthe femoral component in total knee arthroplasty (TKA).Methods: There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittalfemoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cor...

background & aim: dbs (deep brain stimulation) is a new and successful technique in treatment of symptoms of parkinsonism especially after drug resistance. research in this field is mostly designed for evolution of this technique. the present study aimed at evaluating the relationship between the angle formed in midsagittal and stn (sub-thalamic nucleus) axis line and recording length in the fi...

introduction: determining the proper angle for inserting central venous catheter (cv line) is of great importance for decreasing the complications and increasing success rate. the present study was designed to determine the proper angle of needle insertion for internal jugular vein catheterization.  methods: in the present case series study, candidate patients for catheterization of the right i...

BACKGROUND This cadaveric study aimed to demonstrate variation of the anterior cruciate ligament (ACL) tibial attachment in the sagittal plane, and to analyze the radiographic landmarks which predict the sagittal location of the ACL tibial attachment. METHODS In 20 cadaveric knees, native ACLs were removed and the centers of the ACL tibial and femoral attachments were marked with metal pins. ...

BACKGROUND There is no accepted landmark for the mechanical axis of the femoral axis in sagittal plane in conventional total knee arthroplasty. METHODS As palpable anatomic landmarks of the femur, lateral epicondyle, and anterior margin of the greater trochanter were identified. The line connecting these two landmarks was defined as the "palpable sagittal axis". The mechanical axis of the fem...

BACKGROUND The objectives of this paper are to (1) study use of soft tissue analyses advocated by Steiner, Ricketts, Burstone, Sushner and Holdway to develop soft tissue cephalometric norms as baseline data for sagittal lip position in Northeast Chinese adult population, (2) compare the sagittal lip positions in different skeletal malocclusions and (3) compare the sagittal lip positions in Nort...

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 ...
