Abstract

Coxarthrosis is characterized by pain and functional impotence with a consequent load reduction on the diseased limb. This may lead to the onset of secondary localized osteoporosis whose extent depends on the severity and duration of coxarthrosis itself. Materiats and methods: This study aimed to evaluate localized bone mass loss in 17 women with monolateral coxarthrosis due to undergo arthroprosthetic surgery. By way of control the difference of bone mass between the lower limbs of 20 healthy women of the same age, weight and height was also evaluated. Bone density was calculated using ultrasound bone conduction velocity analysis (AUTV). The instrument used for this purpose was a Signet manufactured by Osteotechnology. Results: In 17 women with monolateral coxarthrosis mean AUTV was 1762.06 m/sec in the diseased limb and 1855.2 m/sec in the healthy limb (% difference = 5.0; Student's test: p <0.01). In the control group the mean AUTV of the limb with the fastest velocity was 1874.2 m/sec and 1861.4 m/sec in the contralateral limb (% difference = 0.69; Student's test: NS). Discussion: This study confirms that coxarthrosis leads to the onset of osteoporosis due to the immobility of the affected limb. The ultrasound technique was shown to be a reliable and sensitive method to evaluate this type of osteoporosis. It can therefore be used as an additional means of evaluating hip functional deficiency and the severity of coxarthrosis and might also provide useful indications relating to the choice of the timing and type of surgery to be performed.
