Cam-type hip morphology in asymptomatic patients
HIP InternationalBackground: The alpha angle has been widely used in the assessment of cam-type of impingement, but recent studies have shown that this angle may also be high in asymptomatic patients. The aim of this study is to report the prevalence of cam-type morphology in asymptomatic volunteers and explore its correlation ...

The Etiology of Cam-type Femoroacetabular Impingement: A Cadaveric Study
Journal of Pediatric Orthopaedics, 2017Background: There is a dearth of literature examining the causes of cam-type femoroacetabular impingement (FAI) and when such morphology appears. The purpose of the current study was to analyze how the ossific portion of the proximal femur develops over time with respect to standard cam-type FAI parameters.

Segmentation of cam-type femurs from CT scans
The Visual Computer, 2011We introduce a new way to accurately segment cam-type pathological femurs from pelvic CT scans. The femur is a difficult target for segmentation due to its proximity to the acetabulum, irregular shape and the varying thickness of its hardened outer shell.

CAM-type impingement in the ankle.
The Iowa orthopaedic journal, 2013Anterior ankle impingement with and without ankle osteoarthritis (OA) is a common condition. Bony impingement between the distal tibia and talus aggravated by dorsiflexion has been well described. The etiology of these impingement lesions remains controversial.

New type return-to-zero cam contour
SPIE Proceedings, 1993The equal-angle spiral has been widely used in instrument manufacture. But because of the characteristic of equal-angle spiral the difference between maximum and minimum arms of force is slightly big and the minimum arm of force is slightly small. This is not profitable to the cam.

Journal of Database Management, 2013
The problem of identifying relevant classes (entities) and associations (relationships) is a fundamental problem for conceptual modeling. In a previous work the authors introduced a conceptual modeling methodology named OMP (Ontology-based Modeling Patterns), which is based on the analysis of class categories representing entity types that are ...

On A Class of Cam-Type Angular-Motion Compensators
Journal of Engineering for Industry, 1973The kinematic analysis and static force analysis is described for a class of angular-motion compensators, in which the phase angle between two concentric shafts is controlled by a fixed cam in the form of an eccentric, and a roller follower bearing against two spring-loaded rollers mounted on the shafts.

Cam and Pincer Type of Femoroacetabular Impingement.
Journal of surgical orthopaedic advances, 2017Femoroacetabular impingement (FAI) has gained considerable attention for the past 20 years and has been accepted as a predisposing factor for early osteoarthritis in young patients, particularly in the population participating in sports. Patients with FAI typically present with deep, intermittent groin discomfort during or after activities involving ...
