Although avascular necrosis of the hallucal sesamoid has not been frequently addressed in the literature, it should be considered in the differential diagnosis of persistent forefoot pain. We experienced 3 cases of avascular necrosis of the hallucal sesamoid with sclerosis of the sesamoid bone on radiograghs and computed tomograghy images. T1 and T2-weighted MRI images in 2 patients showed low signal intensity in the sesamoid bone, which suggested osteonecrosis and confirmed by histology. We report 3 cases of avascular necrosis of sesamoid with a review of the literature.

Gout in the sesamoid of the great toe is very rare, such that to our best knowledge, there have been only four reports internationally. We present a case of hallucal medial sesamoid gout in the respect of the literature review, clinical, pathological features and surgical outcome.

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.

The hallucal interphalangeal sesamoid bone is usually asymptomatic, but it is not uncommon for it to be symptomatic in cases of undue pressure, overuse, or trauma. Even in symptomatic cases, however, patients often suffer for extended periods due to misdiagnosis, resulting in depression and anxiety that can steadily worsen to the extent that symptoms are sometimes mistaken for a somatoform disorder. Dynamic ultrasound-guided evaluations can be an effective means of detecting symptomatic sesamoid bones, and a simple injection of a small dose of local anesthetics mixed with steroids is an easily performed and effective treatment option in cases, for example, of tenosynovitis.

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.

Osteochondroma is one of the most common bone tumors. It can occur anywhere, although it is most frequent mainly around the metaphysis of long bones. Prediction sites are distal femur, proximal humerus, proximal tibia, and so on. However, osteochondroma in sesamoid is very rare. Herein, we report a case of a 56-year-old woman with symptomatic extra-articular osteochondroma in hallucal sesamoid with a brief literature review.

Purpose: To treat hallux valgus in old age patients with chevron metatarsal osteotomy and to see the subsequent clinical and radiological outcomes. Materials and Methods: 23 cases of 18 hallux valgus patients of age 60 years or older who received proximal or distal corrective osteotomy from April 2007 to August 2009 and were followed up for at least 1 year were included in the study. The mean age at operation was 65 years (range, 60~81 years), and the mean follow-up period was 2 years and 6 months (range, 1 year~3 years 6 months). Clinical outcome was assessed with the American Orthopaedic Foot and Ankle Society (AOFAS) score, complications, satisfaction rate, as well as measurements and comparison of pre- and postoperative hallux valgus angles, the 1st~2nd intermetatarsal angle, and the position of hallucal medial sesamoid bone. Results: The AOFAS score was improved from preoperative average of 35.1 (range, 13-47) to average 85.1 at last follow-up (range, 75-100). Patients were satisfied about the operation in 21 cases (91.3%). Preoperative hallux valgus angle was $31.7^{\circ}$ on average (range, $19.1^{\circ}-48.9^{\circ}$), and $4.9^{\circ}$ on average at last follow-up (range, $0.3^{\circ}-21.2^{\circ}$). The 1st~2nd intermetatarsal angle was $14.4^{\circ}$on average (range, $8.7^{\circ}-25.7^{\circ}$) and $3.1^{\circ}$ on average at last follow-up (range, $0.6^{\circ}-7.5^{\circ}$). The hallucal medial sesamoid bone position was improved from preoperative average 3.5 (range, 3-4) to postoperative average 1.0 (range, 0-2). Conclusion: Proximal and distal metatarsal osteotomy treatment yielded good clinical and radiological outcomes in old age hallux valgus patients.
