Models, Anatomic

OBJECTIVE: The purpose of this study was to develop a novel pelvic model and determine the accuracy and the inter- and intraexaminer reliability of anterior superior iliac spine (ASIS) positional asymmetry assessment from both sides of the model by osteopathic predoctoral fellows and osteopathic physicians and to evaluate the effect of training. METHODS: Five osteopathic predoctoral fellows and 5 osteopathic physicians assessed 13 settings of varied ASIS asymmetry of a novel pelvic model for superior/inferior positional asymmetry from both sides of the model in a random order.

BACKGROUND: The acquisition of flatfoot by an adult is thought to primarily be caused by posterior tibial tendon dysfunction, although some other causes, such as congenital flexible flatfoot or an accessory navicular, may also be responsible. The objective of this study was to evaluate the bone rotation of each joint in the medial longitudinal arch (MLA) and compare the response in healthy feet with that in flat feet by analyzing the reconstructive three-dimensional (3D) CT image data during weightbearing.

The Human Connectome Project (HCP) faces the challenging task of bringing multiple magnetic resonance imaging (MRI) modalities together in a common automated preprocessing framework across a large cohort of subjects. The MRI data acquired by the HCP differ in many ways from data acquired on conventional 3 Tesla scanners and often require newly developed preprocessing methods.

BACKGROUND: Current knowledge is lacking concerning the appropriate site of osteochondral allograft harvest to match glenoid shape for the purposes of glenoid resurfacing. This has led to difficulty with adequate restoration of the geometry of the glenoid with currently available techniques. HYPOTHESIS: The medial tibial plateau will provide a suitable osteochondral harvest site because of its concavity and anatomic similarity to the glenoid. STUDY DESIGN: Descriptive laboratory study.

The 'idiopathic' dacryostenosis has not yet been cleared up in its aetiological aspects. For further explanation of aetiology and pathomechanisms an experimental, anatomical study was made. Its object was to define the angles and measurements within the bony lacrimal structures and to establish possible connections between the development of the postsaccal stenosis and certain bony constellations of the lacrimal system.

We used the Honan intraocular pressure reducer, a balloon that applies a constant force, to the eyes in ten subjects with senile cataracts. An initially significant decrease in intraocular pressure after removal disappeared exponentially with a half-time of 9.6 minutes, indicating that the benefits derived from the Honan balloon do not result from a sustained reduction in intraocular pressure. Measurements made on a phantom eye showed both marked variability and unexpectedly high intraocular pressure during typical preoperative digital massage by a group of ophthalmic surgeons.

Intentional modification of the infant's head has been commonly practiced at all times and in virtually every region of the inhabited world. Motives included aesthetic perception of the human head, greater attractiveness, symbolization of ethnic identity, demonstration of noble origin or sociocultural status, and supposed health benefits. The desired shape was achieved by repeated hand massage, or by using devices like cradleboards, which were applied throughout infancy. In some regions, infant head shaping was the rule rather than the exception.

X-raying the entire spinal column in the standing position in a single exposure (mainly the AP projection) is an often-used chiropractic radiography procedure which has also found some application in medical scoliosis screening program. Aside from any controversy of clinical objectives or medical necessity, the primary agreed-upon requisite for such procedure is twofold; achieving the best possible film image quality with the least amount of radiation exposure to the patient.

As primary contact practitioners, chiropractors must be competent to screen patients for the presence of visceral disease. Special "clinical" preparation is required to provide students with adequate diagnostic skills in this area in view of the "select" group of patients frequenting chiropractic clinics--the vast majority of chiropractic patients present with musculoskeletal disorders or pain syndromes.

OBJECTIVES: To evaluate the accuracy of anatomical assumptions made to derive a geometrical, ideal, normal model of the upright, static, sagittal cervical spine, to make comparisons with other spinal models and to discuss the implications of a normal cervical model. BACKGROUND: Anatomical assumptions were made based on observations to assist in the development of a computerized geometrical model of the ideal upright, static, sagittal cervical spine.
