Purpose: This study was conducted to determine the structural change in knees caused by quadriceps angle and the muscle activity in lower limbs. Indirect intervention was provided by using taping for stability in the ankle joints, which affected patellofemoral pain. Methods: The subjects in this study were 20 patients with patellofemoral pain who visited ${\bigcirc}{\bigcirc}{\bigcirc} $ Hospital in Busan. The visual analogue scale measured the dynamic quadriceps angle and the degree of pain felt by the patients while walking down stairs, which was a known factor of patellofemoral pain. In addition, muscle activities in the rectus femoris, vastus lateralis, vastus medialis, tibialis anterior, peroneus longus, and biceps femoris, which affect the knees and ankles, were measured using surface electromyography. The muscle activities were converted into %RVC for this study. The data obtained in this study were analyzed with the Wilcoxon signed-rank test using the SPSS Ver. 25.0 statistical program. The significance level ${\alpha}$ was 0.05. Results: The study results showed that the pain and dynamic quadriceps angle were significantly reduced statistically when applying the calcaneus fixation taping (p<0.05). Muscle activity in the lower limbs was significantly decreased in the vastus medialis, vastus lateralis, and tibialis anterior (p<0.05). Conclusion: The summary of the study results verified that the calcaneus fixation taping reduced the pain and dynamic quadriceps angle by providing stability in the ankle joints. It also produced efficient movement due to the difference in lower-limb muscle activity.

비교적 흔한 골의 양성 질환으로 소파술 및 골 이식술, 절제술, 스테로이드 또는 골수 주입법 등이 일반적으로 시행되는 단순 골낭종은 비교적 낮은 빈도로 종골에 발생하게 되며, 종골에 발생 시, 기존의 스테로이드 주입술보다는 관혈적 소파술 및 골 이식술이 주로 시행된다. 저자들은 9세 남아에서 발생한 종골의 단순 골낭종에 대해 최소 침습적 술기를 통한 내시경적 소파술 및 골 이식술을 통해 좋은 결과를 경험하였기에 문헌 고찰과 함께 보고하고자 한다.

골연골종은 가장 흔한 양성 골 종양으로, 성장판에서 기원한 명확하게 구별되는 연골모를 가지고 있다. 호발 연령은 20세 이하의 환자에서 주로 발생하며, 성장에 비례하여 종양의 크기가 커지다가 골격계의 성숙과 함께 종양의 성장이 멈춘다. 골연골종의 호발 부위는 주로 장 관골의 골간단부와 편평골에서 발생하나, 족부에서는 낮은 발생 빈도를 보인다. 족부에서는 대개 중족골과 족지골에 발생하며 종골에서의 발생은 매우 드문 것으로 알려져 있다. 본 교실에서는 15세 남아에서 발생한 종골 내측 족저부 조면에 발생한 단발성 골연골종을 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

유잉육종은 소아와 청소년기에 발생하는 악성 골종양으로 주로 긴 뼈의 골간에 발생한다. 손과 발에 발생하는 유잉육종은 매우 드물다. 저자들은 왼쪽 발꿈치뼈에 발생한 유잉육종 1예를 경험하였기에 문헌 고찰과 함께 보고한다. 15세 여자가 왼쪽 발꿈치의 동통과 부종을 을 주소로 내원하였다. 방사선 소견에서 왼쪽 발꿈치뼈에 골용해성 및 골경화성 병변이 관찰되었다 수술 전 시행한 생검에서 종양세포들은 균일한 둥근 모양의 종양세포로 구성되어있었다. CD99에 대한 면역조직화학염색에서 대부분의 종양세포의 세포질이 강한 양성반응을 보였다. 유잉육종으로 진단을 하고 화학요법을 한 후 무릎밑절단을 시행하였다.

The aim of the present study was to investigate effect of running speed conditions on the kinematic pattern of the metatarsus, mid-foot, calcaneus. Twenty-two healthy young adults were made to run on treadmill at three different running speeds(normal speed, 9.2; slow speed, 7.4; fast speed, 11.1km/hr.) and the trajectories of the 10 reflective markers for each subject were recorded by an eight-camera motion capture system at 200 Hz. Three-dimensional angles for the foot segment in the support phase during running were calculated according to Euler's technique. Results showed that running speed did not affect the peak of the dorsi/plantar flexion, inversion/eversion, and adduction/abduction or their range of motion for each foot segment. However, when the running speed was fast, significant differences were found in the peak of the plantar flexion, eversion, and adduction and ROM(range of motion) of the dorsi/plantar flexion, inversion/eversion, and adduction/abduction between the foot segments, metatarsus, mid-foot, and calcaneus. It was proposed that the foot segment should be analyzed from a multi-segment system point of view on the basis of anatomical reference during locomotion.

Secondary soft tissue injuries can occur from the pressure of the displaced fragment of posterior calcaneal tuberosity in calcaneal tongue-type fractures and calcaneal tuberosity avulsion fractures. The soft tissue injury can be prevented by immediate reduction of the displaced fragments. Various techniques can be used to fix the fracture fragments, but the stability of fixation and minimal invasiveness to soft tissue should be considered. This paper reports the successful outcomes of patients with soft tissue compromises in calcaneal tongue-type fractures and calcaneal tuberosity avulsion fractures. The fixation technique of a large cannulated screw and simple cerclage wiring is believed to be a useful surgical option for the treatment of secondary soft tissue compromised calcaneal fractures.

Displaced intra-articular calcaneal fractures are difficult to treat because of complex anatomy and high soft tissue complications. Various surgical approaches have been introduced to solve these problems, but the treatment remains complex. Recently, clinically and radiographically superior results were reported using a subtalar arthroscopy in reducing the posterior facet in both percutaneous and open approaches. In the percutaneous approach, the arthroscopically assistant percutaneous approach must be selected carefully for mild-to-moderately displaced fractures because of the limited view. In the open approach, there is little evidence of the utility of subtalar arthroscopy. Therefore, intraoperative arthroscopy should always be used in conjunction with fluoroscopy to achieve reduction and assess the internal fixation placement.

The development and change of the cartilage canals ralated to chondrocyte growth and the major histological pattern were investigated in the calcaneus of the Korean native cattle fetuses from CRL 28mm to 175mm. The results as follows; 1. The cartilage canal first appeared in the caudal subperichondral region of the sustentaculum tali of the CRL 28mm fetus, and well developed after the period. 2. The three major cartilage canals, one entered from the head of calcaneous into where achilles tendon insert and the others from the caudal region of sustentaculum tali and the calcaneal sulcus, growth distinctively. The latters participated in the ossification center prior to the former. 3. The number of cells in this canals and the size increased synchronously with chondrocytic hypertrophy. In the intermediate and deep canals, the chondrogenic change showed distinctinvely. Our results demonstrated that the cartilage canals from the lower part were important the formation of the ossification center, and the growth and development of canals associated with the hypertropic changes of chondrocytes in the calcaneus of the Korean native cattle fetus.

Purpose: To evaluate the clinical efficacy of the limited posterior approach for the surgical treatment of intraarticular fracture of calcaneus. Materials and Methods: From March 2000 to February 2006, we studied retrospectively 186 patients, 203 cases who were treated with open reduction and internal fixation through limited posterior approach and were followed up for more than 1 year. The clinical results were evaluated with Creighton-Nebraska score and circle draw test after 1 year. We checked simple AP, lateral, axial and Broden's view preoperatively and 1 year after surgery, and compared $B{\ddot{o}}hler$ angle and Gissane angle. Results: By Creighton-Nebraska score, Sanders type 2 was 86.4, type 3 was 74.3, type 4 was 62.4. And by circle draw test, type 2 was 8.9 cm, type 3 was 7.2 cm, type 4 was 5.9 cm. $B{\ddot{o}}hler$ angle and Gissane angle were $7.6^{\circ}$, $102.4^{\circ}$, and it increased to $23.5^{\circ}$, $128.6^{\circ}$ after postoperative 1 year. Conclusion: Limited posterior approach for the surgical treatment of intraarticular fracture of calcaneus was considered to an effective treatment modality.
