Alterations were made to the cortical thickness (Tc) via the following power function: T = a + bσ n (2 quality 20 mg inderal. Following an iterative process, the final stage (considered an equilibrium point) closely resembled the geometrical configuration of the actual bone. The rationale for the algorithm defining his model was not explained in detail; nonetheless, his efforts established the capabilities of a simplistic model to predict generalized adaptive geometries. Kummer63 advanced a concrete form of Pauwels’ theory which has been carefully reviewed by Firoozbakhsh and Cowin. The cubic relationships developed by Kummer accounted for the adaptive changes associated with pressure necrosis, but neglected those associated with disuse atrophy. Cowin’s Adaptive Elasticity Theory The mathematically rigorous and potentially powerful theory proposed by Cowin and colleagues,56,65-67 was developed to describe the physiological adaptive behavior of bone. The basic hypothesis governing the thermomechanical continuum theory of adaptive elasticity is that the load-adapting properties of living bone can be modeled by a chemically reacting porous medium in which the rate of reaction is strain controlled. The objective was to model bone as a porous elastic solid and to model the normal adaptive processes that occur in bone remodeling as strain controlled mass deposition or resorption processes which modify the porosity of the porous elastic solid. In addition, it was shown that remodeling will not occur in a long bone, such as the femur, as a result of a purely torsional load about its long axis. In the years that followed, Cowin and Firoozbakhsh68 presented a somewhat less rigorous surface adaptation model in which bone assumed a site-specific homeostatic equilibrium strain state. Control equations, in which the rate of remodeling is proportional to the deviation from a reference (homeostatic) value were developed. Consequently, any aberrant strain state would influence bone remodeling in an attempt to reinstate homeostatic conditions via the following formula: o U ij ij ij (2.

It should © 2001 by CRC Press LLC be noted that the authors relied on generality for the choice of Cij, without reference to a biological basis.

She has significant pain at 12 of the 18 tender points order 20mg inderal with amex, and there is a mild reduction in strength in all extrem- ities. Which of the following statements regarding the physical examination findings of fibromyalgia is false? Evidence of synovitis, objective muscle weakness, or other definite physical or neurologic signs suggests the presence of either a comorbid disease or an alternative diagnosis B. When assessing tender points, palpation is performed with the thumb, using approximately 4 kg of pressure C. For an accurate diagnosis, the examiner must confirm pain at all 18 tender points D. Useful tests in fibromyalgia include antinuclear antibody (ANA), com- plete blood count (CBC), erythrocyte sedimentation rate (ESR), C-reac- tive protein (CRP), thyroid-stimulating hormone (TSH), creatine kinase (CK), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) 15 RHEUMATOLOGY 35 Key Concept/Objective: To know the important components of the physical examination of a patient with fibromyalgia Evidence of synovitis (e. Eighteen specific tender points have been identified in fibromyalgia. A patient with fibromyalgia will have pain, not just tenderness, on palpation at many of these tender points. Palpation is performed with the thumb, using approximately 4 kg of pressure—about the pressure necessary to blanch the examiner’s thumbnail. Attempting to confirm pain at all 18 tender points is not necessary for diagnosis and is inconsiderate toward patients, many of whom find tender-point pal- pation quite distressing. Useful tests in fibromyalgia include the following: ANA, CBC, ESR, CRP, TSH, CK, AST, and ALT. Tests for Lyme disease, Epstein-Barr virus infection, and endocrinologic status are usually unnecessary.
