RESUMO

To identify a proper T-score threshold for the diagnosis of osteoporosis in Koreans using quantitative ultrasonography (QUS), normative data from 240 females and 238 males (ages 20-29 yr) were newly generated. Then, the osteoporosis prevalence estimate for men and women over 50 yr of age was analyzed using previous World Health Organization (WHO) methods and heel QUS. T-scores were calculated from the normative data. There were definite negative correlations between age and all of the QUS parameters, such as speed of sound (SOS), broadband ultrasound attenuation (BUA), and estimated heel bone mineral density (BMD) (p<0.0001). After applying the recently determined prevalence of incident vertebral fracture in Koreans over 50 yr of age (11.6% and 9.1%, female vs male, respectively) to the diagnosis of osteoporosis by T-scores from heel BMD as measured by QUS, it was revealed that applicable T-scores for women and men were -2.25 and -1.85, respectively. These data suggest that simply using a T-score of -2.5, the classical WHO threshold for osteoporosis, underestimates the true prevalence when using peripheral QUS. Further prospective study of the power of QUS in predicting the absolute risk of fracture is needed.

RESUMO

A majority of heel ulcers, at least to begin with, extend to dermis or to the fat pad in its superficial part and an appropriate skin closure can heal these ulcers as most of the padding is in tact. Since the skin is adherent to the deeper structures with fibrous bands it has to be stretched or undermined (by cutting the fibrous bands) to close the wound without tension. 17 feet in 11 patients (10 males; one female) in the 12-54 year age-group were operated upon and followed up. Because skin is adherent to deeper tissues by fibrous septae, stretching of skin was planned to mobilize it for a tension-free closure. Of the 17 feet, 13 could be re-examined after 30 months or more. Most of the minor recurrences were seen in the first 6 months after surgery. Major recurrences were seen in 2 feet (one case). The suture line did not show hyperkeratosis and the scar merged well into the surrounding skin after one year. Available data suggest that simple heel ulcers can be made to heal with a good scar by skin-stretching and suture, and, by radiography of the foot, it is worth separating those cases in which ulcer is not extending deep involving calcaneum. The size of the ulcer in heel is important for the success of the operation. The procedure is not intended for big wounds (>15 mm in width).
