Purpose: To determine the locations and incidences of sesamoids and accessory bones of the forefoot in normal Korean adults. Materials and Methods: The plain radiographs of the forefoot of 400 volunteers, 200 males and 200 females, were taken. The three orthopedic surgeons participated in the radiographic evaluation independently. Persons who had history of foot problem or injury were excluded. Results: Sesamoids of first metatarsophalangeal joint were nearly always present; medial 99% and lateral 100%. The bipartite sesamoid was more common in medial (9.8%) and in female (17.0%) than in lateral (0.3%) and in male (2.5%). Sesamoids of the interphalangeal joint of the first toe were seen in 35.8%. Sesamoids of metatarsophalangeal joints in other four toes were rarely observed. Their incidences were 5% in second toe, 0.8% in third, 0% in fourth, and 2.8% (lateral) and 7.5% (medial) in fifth. Sesamoids of interphalangeal joint in four lesser toes were not observed except two cases (0.5%) in the fifth toe. Accessory bone was very rarely observed. Os vesalianum was observed in five feet (1.3%), Os intermetatarseum in 14 feet (3.5%), and Os cuneo-metatarsal I tibiale in none. Conclusion: We determined the location and incidences of sesamoids and accessory bones of the forefoot, and we expected this to help to diagnose the forefoot problem.

Purpose: Frequency of sesamoid bone on hallucal interphalangeal joint has been described to be low probability in orthopaedic and anatomical literature. We have, however, experienced two cases of interphalangeal joint dislocation giving difficulty to usual manipulative reduction because of presence of sesamoid bone recently. In order to ascertain existence of sesamoid bone on interphalangeal joint of hallux in Korean adults, radiological study have been performed with feet of patients Materials and Methods: Between May 2003 and October 2006, 974 patients with 1098 radiographs of feet which were reached skeletal maturity over 18-year-old were examined. Unilateral or bilateral anteroposterior, lateral and oblique radiographs were observed by one same person and presence was recorded if there was sesamoid in films. Distance of long and short axes were measured in lateral view and cases of two sesamoids in interphalangeal joint were recorded. Statistical differences between left and right side or between men and women were evaluated by chi-square test. Results: Frequency of sesamoid was 980 cases (89.3%) and no occurrence in 118 cases (10.7%). Two sesamoids were observed in 3 cases. Average distance of long axis was 4.9 mm (range, 0.5-11.4) and average distance of short axis was 3.5 mm (range, 0.3-9.3). Unilateral sesamoid was observed in 7 patients (5.6%), bilateral absence was 7 patients (5.6%) and bilateral sesamoids in 110 patients (88.8%) out of 124 patients who took bilateral feet radiographs. Men has less frequency than women significantly (p=0.014) while there was no significant difference in frequency according to side(p>0.05). Conclusion: Sesamoid bone was seen in 980 feet (89.3%) out of 1098 normal Korean radiological studies of feet. We report 3 cases of two seamoids which was extremely rarely reported in literature. Korean frequency is similar with Japanese, but much higher than Caucasians and black Africans.

종자골과 부골은 정상 해부학적 변이로 그 빈도와 형태는 다양하며 일반적으로 크기가 작고 둥근 모양으로 피질로 잘 둘러싸여 있고 뼈나 관절 주위에 인접하여 관찰되고 드물게 이분 혹은 다분 형태를 보일 수 있다. 대부분의 종자골과 부골은 무증상이며 판독 업무 중에 흔히 마주치게 된다. 하지만 때때로 종자골과 부골이 증상을 일으킬 수 있는데, 종자골과 부골 자체의 골절이나 탈구, 관절염, 골괴사, 감염 등의 질환이 이환되거나, 주변에 신경압박이나 건초염, 연부조직의 포착 등에 의하여 증상을 유발할 수 있다. 이 종설에서는 다양한 해부학적 위치에서 발생한 증상이 있는 종자골과 부골의 영상을 보고, 이들의 임상적 양상과 영상의학적 감별진단을 정리해보고자 한다.

족무지 종자골의 불유합은 주로 스트레스 골절의 후유증으로 나타나며 보존적인 치료에도 증상이 지속되는 경우 수술이 시도될 수 있다. 저자들은 과사용 후에 족무지의 내측 이분 종자골 및 외측 종자골에 동시에 발생한 스트레스 골절의 드문 예를 경험하였으며, 석고 고정에 치료되지 않은 내측 종자골의 불유합에 대해서는 소파 및 골이식술을 이용하여 만족할 만한 결과를 얻었기에 그 결과를 보고하는 바이다.

This study was peformed to investigate the morbidity of nutritional secondary hyperparathyroidism(NSH) caused by imbalance of Ca and p, and related athletic disease in Cheju pony racehorse. The seventeen horses with clinical signs among 33 NSH affected, administered CaCO$_3$(34 g) and Vita-rinka1(120 g) respectively for 40 days. The results were asd follows; Morbidity of NSR was 33 among 47 horses, and it was caused by the deficiency of Ca in 32 horses. In a case, level of Ca was norm질 although P was high. There was no case of Ca deficiency with P excess. Among 33 NSH affected horses, 13 were subclinical and 20 were clinical types with severe lameness in 6 and transient lameness in 14. Although there was no difference in bone density between transient lameness and normal horses on radiography, among six horses wlth severe lameness two showed hyperplasia at periosteum, one had low density of phalanges and metacarpal bones, and thin cortex. and there with fracture at carpus, nivicular bone and proximal sesamoids. The levels of FECa and FEP were recovered after CaCO$_3$ administration in 2 horses among ten, and after Vita-rinkal in all of seven. The clinical signs were disappeared in slx horses among ten CaCO$_3$ treated, and in five among seven Vita-rinkal treated. There were no differences on radiography in bone density and thickness of cortex on 14 horses with transient lameness. Three horses with severe signs were recovered to normal bone density and thickness of cortex, and there was no significant difference between two groups. In summary, the morbidity of NSH in Cheju pony racehorses was relatively high because of deficiency of Ca. Constant admistration of Ca supplements is desirable to treat and prevent athletic disease development in Cheju racehorses.
