Osteosarcoma is mainly developing around the knee joint. But osteosarcoma of the calcaneus is rare. A 20 year old male patient visited our clinic due to persistent pain around the calcaneus. We diagnosed it to osteosarcoma of the calcaneus and treated with below knee amputation and adjuvant chemotherapy. We experienced a case of osteosarcoma of the calcaneus and would like to report it with review of literatures.

Chondosarcoma of the calcaneus in young child is extremely rare. A thirteen-year old male patient has suffered from right heel pain for several months before. Dominant gross feature was hard mass and swelling on one entire right heel, and increased density and calcification on entire calcaneus with cortical destruction, and calcific densities on soft tissues around calcaneus were seen on roentgenogram of right ankle. It was diagnosed to be chondrosarcoma by bone biopsy. It was treated by below knee amputation and chemotherapy, and no recur and distant metastsis during 12 months after operation.

In this in vivo study, correlations of lumbar and femoral bone mineral densities (BMDs) with calcaneal speed of sound (SOS) were investigated in 36 osteoporotic women. Areal BMDs of the L2-L4 lumbar spine and the right femoral neck were measured by using dual energy X-ray absorptiometry (DEXA). SOS of the right calcaneus was measured by using ultrasound bone densitometry. Pearson's correlation coefficient (r) and level of significance (p) were used to evaluate the correlations between measurements. Lumbar BMD was highly correlated with femoral BMD (r=0.81). Lumbar and femoral BMDs exhibited similar comparable negative correlations with age (r=-0.52 and r=-0.55). A moderate negative correlation was found between calcaneal SOS and age (r=-0.45). Calcaneal SOS was significantly correlated with lumbar and femoral BMDs, with a higher correlation with femoral BMD rather than with lumbar BMD (r=0.54 and r=0.62). However, calcaneal SOS may not be an optimum index for the estimation of BMD of the most important fracture sites, such as the lumbar and the femur, because it showed lower correlations with lumbar and femoral BMDs compared to that with calcaneal BMD. Therefore, the development of a quantitative ultrasound technology for the direct measurement of acoustic properties at the lumbar and the femur is required to estimate BMD of these sites more accurately.

Simple bone cysts are common, benign bone tumor and for the treatment, curettage with bone grafting, resection and intralesional steroid or autogenic bone marrow injections were usually performed. Simple bone cysts of the calcaneus are relatively uncommon and curettage with autologous bone grafting were proposed for management rather than intralesional steroid injections. We would like to report 9 year-old male with calcaneal simple bone cyst treated satisfactorily by minimally invasive endoscopic curettage and autologous bone grafting with review of the relevant literature.

Enchondroma is a benign tumor mainly developed in the hand and uncommon in the foot. Even if it is in the foot, most are in the phalanges and distal metatarsals of the foot. Enchondroma in the calcaneus is very rare. A 44-year-old male suffered from left heel pain for several months, authors treated it with curettage and bone graft, it was histologically confirmed as an enchondroma in the calcaneus. The authors presented a rare case presentation of an enchondroma in the calcaneus with pain.

Purpose: Accurate clinical evaluation of the alignment of the calcaneus relative to the tibia in the coronal plane is essential in the evaluation and treatment of hindfoot pathologic condition. Previously described standard anteroposterior, lateral, and oblique radiographic methods of the foot or ankle do not demonstrate alignment of the tibia relation to the calcaneus in the coronal plane. The purpose of this study was to introduce hindfoot coronal alignment view. Material : 1) Both feet were imaged simultaneously on an elevated, radiolucent foot stand equipment. 2) Both feet stood on a radiolucent platform with equal weight on both feet. 3) Both feet are located foot axis longitudinal perpendicular to the platform. 4) Silhouette tracing around both feet are made, and line is then drawn to bisect the silhouette of the second toe and the outline of the heel. 5) The x-ray beam is angled down approximately $15^{\circ} to $20^{\circ} Result : 1) This image described tibial axis and medial, lateral tuberosity of calcaneus. 2) Calcaneus do not rotated. 3) The view is showed by talotibial joint space. Conclusion: Although computed tomographic and magnetic resonance imaging techniques are capable of demonstrating coronal hindfoot alignment, they lack usefulness in most clinical situations because the foot is imaged in a non-weight bearing position. But hindfoot coronal alignment view is obtained for evaluating position changing of inversion, eversion of the hindfoot and varus, valgus deformity of calcaneus.

The Purpose of this study is to compare the bone marrow density measured by quantitative ultrasonometry (QUS) between men and women. Questionnaires for general characteristics were obtained from 104 participants, and then their both calcaneus was measured by using QUS. Sex differences for bone marrow density (BMD) were analyzed by an Independent t-test using the SPSS 19.0 program. Of 104 participants, women and men were 69(66.3%) and 35(33.7%), respectively. T-value of left calcaneus was high significantly in women than that in men(0.443 vs. 0.031, p=0.161) as well as that of right calcaneus(0.555 vs. 0.049, p=0.093). T-value of right calcaneus was high than that of left calcaneus in women and men (not significant, p>0.05). T-value of both calcaneus was increasing with physical activity. T-value of calcaneus was no statistically significant with age and body mass index. The BMD of women is high significantly more than that of men, and BMD is relation with physical activity.
