Sports Medicine and Arthroscopy Review, 2010
Hip instability is becoming a more commonly recognized source of pain and disability in patients. Traumatic causes of hip instability are often clear. Appropriate treatment includes immediate reduction, early surgery for acetabular rim fractures greater than 25% or incarcerated fragments in the joint, and close follow-up to monitor for avascular ...

Unlike aneuploidy, considered to be the cardinal feature of malignant tumors ever since the chromosomal analysis of neoplastic cells became technically feasible, a second pathway toward malignancy has emerged over the past decade that is not characterized by gross aneuploidy but, instead, by inactivation of the DNA mismatch repair system, leading to a ...

Clinical Orthopaedics and Related Research, 1992
The various definitions of instability are reviewed and preference is given to the definition of instability as a loss of stiffness. This definition fits with current laboratory observations. Roentgenographic changes, particularly those associated with degeneration, have no relationship to instability.

Studies in Applied Mathematics, 1969
A uniform train of periodic waves may be unstable to large scale variations so that some incoherence can develop. The analysis is presented for the case of gravity waves, and for a class of interaction problems typical of many physical systems.

Hand Clinics, 1987
The pathomechanics of midcarpal instability are described, particularly as they relate to the ring model of the wrist. A review of the clinical history, evaluation, and treatment of patients with midcarpal instability is presented.

Physical Review E, 2000
In 1982 Bobylev [A.V. Bobylev, Sov. Phys. Dokl. 27, 29 (1982)] made a linear stability analysis of the Burnett equations and showed that beyond a certain critical reduced wave number there exist normal modes that grow exponentially, concluding that the Burnett equations are linearly unstable. We have partially extended his analysis, originally made for

European Radiology, 2006
This review addresses the pathoanatomical basics as well as the clinical and radiological presentation of instability patterns of the wrist. Carpal instability mostly follows an injury; however, other diseases, like CPPD arthropathy, can be associated.

The clinic diagnosis of degenerative lumbar intervertebral instability is a controversial topic and have not yet been clarified clinical criteria for to define this condition with accuracy. Although the lumbar pain is the most common symptom in patients who have lumbar intervertebral instability its clinical presentation is not specific; moreover in ...

Recurrent patellar instability can result from osseous abnormalities, such as patella alta, a distance of >20 mm between the tibial tubercle and the trochlear groove, and trochlear dysplasia, or it can result from soft-tissue abnormalities, such as a torn medial patellofemoral ligament or a weakened vastus medialis obliquus.
