Cortical Bone Remodeling and Bone Mass in Primary Osteoarthrosis of the Hip

Bone Mineral in Patients with Osteoarthrosis of the Hip

“…Our results contradict the findings of Foss & Byers 11972) and Roh et al (1973Roh et al ( , 1974. One explanation for this may be the different compositions of the control series in the various studies.…”

“…Roh et al (1973) postulated that the larger metacarpal bone inass of patients with osteoarthrosis of the hip was due to normal endosteal resorption and to increased periosteal apposition as compared with controls matched for age and sex. Using photon absorption, they also demonstrated that the mineral content of the forearms of osteoarthrotics was higher than that of controls (Roh et al 1974).…”

Bone Mass in Primary Coxarthrosis

“…Foss & Byers (1972) measured the cortices of the second metacarpal in patients with coxarthrosis and those with fracture of the upper end of the femur and found that coxarthrosis cases had higher values than the controls whereas fracture cases were below normal. Roh et al (1973) found similar changes in the second metacarpal bone of coxarthrosis cases -the dimensions of the bones indicated an increased periosteal apposition rate with normal endosteal resorption rate, resembling the bone remodelling changes in acromegaly. Using a method of photon absorption measurement of bone mass Roh et al (1974) found that not only the metacarpal bones but also the shaft and the distal end of the radius showed an increased bone mineral content in cases with coxarthrosis as compared with healthy controls.…”

“…27 Conversely, disorders that result in removal of mechanical stimulus during growth, such as cerebral palsy, spina bifida, or poliomyelitis, lead to thin bones in the affected segments. [28][29][30] …”
