Haglund's syndrome produces retrocalcaneal bursitis or achilles tendinitis due to impingement of posterior superior bursal projection of calcaneus on insertional fibers of achilles tendon. Haglund's syndrome has been mainly associated with wearing rigid counter shoes and with athletes. We experienced three case of late sequelae of secondary Haglund's syndrome after malunion of tongue type calcaneus fracture. It is to be the first description of secondary Haglund's syndrome after calcaneus malunion and also the first report as the late complication of calcaneus fractures. Three cases were all tongue type intraarticular fractures and were treated with $45^{\circ}$ superior angle resection of superior calcaneal tuberosity. Clinical results by modified Rowe score were excellent with complete pain relief for all three cases.

Calcaneus fracture with a subtalar dislocation are extremely rare. A case of a joint depression type calcaneus fracture with a lateral dislocation of the calcaneal posterior facet and tuberosity is presented. We treated it with open reduction and internal fixation with Steinmann pins and K-wires through limited posterior approach and obtained satisfactory radiographic and clinical outcome.

The current cadaveric report aims to present a coexistence of two uncommon variants of the posterior leg compartment. The variations were detected, during classical dissection in an 84-year-old donated male cadaver. On the left lower limb, the gastrocnemius muscle was identified as having a third head that was attached to the lateral head. This variant is known as gastrocnemius tertius muscle and was bilaterally identified. The left-sided plantaris muscle had two distinct heads that fused into a common tendon that was inserted into the calcaneal tuberosity. Knowledge of these variants is important, due to their close relationship with the popliteal neurovascular bundle. Clinicians should be aware, to avoid pitfalls and take them into account in their differential diagnosis.

Avulsion fracture of the calcaneal tuberosity is an uncommon injury. Usually it occurs from indirect trauma, and can be seen in old patients with osteoporosis or in patients with diabetic neuropathy. Follow-up studies showed healing of the fracture in most cases, but skeletal deformity may develop in some cases. Therefore we should take plain X-ray evaluations in diabetic patients with foot and ankle pain, even though there have been no definite trauma history. Four cases of calcaneus avulsion fracture were treated operatively in diabetic patients, and reported.

The location of BL61 has commonly known as directly under the BL60 (Gollyun) which is at the lateral side of the heel. SP2 is located at the front of the big toe joint and SP3 is located at the rear of the big toe joint. These locations are the same with the standard acupuncture points of the WHO/WPRO. However, according to Chimgeumdongin (鍼金銅人), BL61 is located at the center of calcaneal tuberosity, which is close to the bottom of the heel, not at the side. SP2 is located at the rear of the big toe joint, not at the front. SP3 is located at the rear of sesamoid bone, not at the rear of the big toe joint. These can be also found in Douningyou (銅人形) c-544 with the same locations. Moreover, these locations are precisely equal in reference to the acupuncture classics such as < Zhenjiujiayijing : 鍼灸甲乙經 >, < Buzhutongrenjing : 補註銅人經 >, whereas the descriptions of the standard acupuncture points of the WHO/WPRO and the locations of acupuncture points in Zhenjiutongren (鍼灸銅人), Zhinjiuxueweitongren (鍼灸穴位銅人) are totally different from the acupuncture classics. Therefore, there needs to be further examinations on WHO/WPRO Standard Acupuncture Point with various acupuncture bronze men.

Purpose: There are various methods proposed for the evaluation of the hindfoot alignment. However, due to structural calcaneus variances between patients, it is hard to assess this alignment definitively. Thus, this study proposes a new method for evaluating of the hindfoot alignment and its comparisons to the existing current methods. Materials and Methods: This study includes simple weight bearing hindfoot coronal view radiographs of 120 patients, taken between the time period of March 2008 to November 2009. Among the 120 patients, there was a 1:1 ratio of male to female with an average age of 40. The newly proposed method for evaluating this alignment is to draw a moment arm from the point where the sustentaculum tali meets the medial calcaneus border to the most prominent aspect of the lateral process of the calcaneal tuberosity. The angle produced via the intersection of this moment arm to the mid-longitudinal axis of the tibia is found and used to evaluate the hindfoot alignment. The inter and intra-observer reliability was evaluated using the coefficient of intraclass correlation. This study also investigates the comparisons between the newly proposed method to the traditionally used Saltzman et al hindfoot alignment evaluating technique. Results: The newly proposed method has higher inter and intra-observer reliability than the existing traditional Saltzman et al technique. Conclusion: This new method is recommended over the traditionally used Saltzman et al technique as it has a stronger confidence level and is appropriate for assessing hindfoot alignment in simple radiographs.

The Cobey method and the modified Cobey method are most commonly used in clinical practice. Therefore, the purpose of this study was to investigate the radiological differences between Cobey and modified Cobey and provide radiographic information about changes of hindfoot image with X-ray entrance center and tube angle change in modified Cobey. This study was performed on foot and ankle phantom. First, for image comparison of Cobey and modified Cobey, the images obtained by applying the same X-ray entrance center to the ankle joint were compared and analyzed. Second, in the modified Cobey, the X-ray entrance center is set as ankle joint and lateral malleolus. The X-ray tube angle was varied from $10^{\circ}$ to $40^{\circ}$ at $5^{\circ}$ intervals for each X-ray entrance center. The images obtained by varying the X-ray tube angle from $10^{\circ}$ to $40^{\circ}$ at intervals of $5^{\circ}$ for each X-ray entrance center were compared and analyzed. The irradiation conditions were the same with 110 kVp, 200 mA, 10 ms, and 110 cm of source - image receptor distance (SID). Image evaluation was performed by two radiologists. Measurements were made on the lateral point, middle point, and calcaneus width based on a hypothetical line parallel to the calcaneal tuberosity. Data were analyzed by using descriptive statistics as the mean of the distance to each measurement location. The modified Cobey was longer than the Cobey by an average of 3 to 4 mm lateral and medial points, and the calcaneus width was similar (ICC = 0.939). In modified Cobey method, when the X-ray entrance center is ankle joint, the lateral point is about 3 mm and the medial point is about 4.3 mm longer than lateral malleolus. Also, when the X-ray tube angle is more than $20^{\circ}$, the degree of distortion is large. The ICCs for the lateral, medial point, and calcaneus width were 0.998, 0.961, and 0.997, respectively, as the X-ray entrance center and tube angle were changed. There was no significant difference between Modified Cobey and Cobey. Modified Cobey showed no need to compensate the $20^{\circ}$ detector angle of the Cobey. In addition, we suggest that tube angle should be limited within $20^{\circ}$ when modified Cobey is performed.

목적 : 신장 이식후 발생한 무혈관성 골괴사의 빈도를 알아보고, 골스캔과 SPECT, MRI의 역할을 비교해 보고자 하였다. 대상 및 방법 : 1989년 6월부터 1995년 9원까지 본원에서 신장 이식을 받은 301명중 임상적으로 무혈관성 골괴사를 진단받은 환자의 발생빈도 및 침범 부위를 알아보고, 무혈성 골괴사 환자에서 시행한 골스캔과 SPECT, MRI 소견을 비교하여 보았다. 결과 : 무혈관성 골괴사의 발생빈도는 3.3%(10/301)였고, 침범 부위는 대퇴골두 16병변과 종골 융기 2병변이었다. 또한 전신 골스캔상 천골의 불충분 골절을 보인 경우가 1례 있었다. 골스캔 소견은 열소에 둘러싸인 냉소 13병변, 열소 3병변, 냉소 1병변, 정상 1병변의 소견을 보였고 열소만을 보인 경우는 SPECT에서는 작은 냉소를 둘러싸는 열소로, 냉소나 정상으로 보인 경우는 SPECT상 반응성 열소 없는 냉소로 나타났다. SPECT와 MRI를 같이 시행한 6례중 모두양성인 경우가 5례였고, 증상이 있었던 1례에서 SPECT상 냉소로 보였으나 MRI에서는 정상소견을 보였다. 결론 : 신장 이식후 발생한 무혈관성 골괴사의 발생빈도는 3.3%였고, 전신골스캔으로 골괴사외의 전신골 병변을 관찰할 수 있었으며 증상은 있으나 골스캔상에서 병변이 뚜렷하지 않거나 MRI에서 음성인 경우 등에 SPECT가 진단에 도움이 되었다. 그러므로 증상은 있으나 MRI에서 음성인 경우 SPECT를 시행하는 것이 신장 이식후의 환자에서 발생하는 무혈관성 골괴사의 진단에 유용하리라고 생각된다.
