육상 선수나 격투기 선수들에게서 전족부 손상은 흔한 편이나 족무지 지간 관절은 해부학적 안정성으로 인해 관절 측부 인대손상은 매우 드문 것으로 알려져 있다. 특히 스포츠 손상에 의한 지간 관절의 만성 불안정성에 대해서는 국내외적으로 보고가 극히 적어 저자들은 대학 태권도 선수에서 족무지 지간 관절의 진구성 외측부 인대 파열에 기인한 만성 무지 내반 불안정성에 대하여 수술적으로 치료하여 좋은 결과를 얻었기에 이를 보고하고자 한다.

Patients with chronic lateral ankle instability often experience a range of associated injuries. The well-known comorbidities include intra-articular pathologies (osteochondral lesion, soft tissue or bony impingement, and loose body), peroneal tendon pathologies, neural injuries, and other extra-articular pathologies. Surgeons should have a high index of suspicion for these associated pathologies before operative intervention, correlate the clinical findings, and plan the treatment. Despite the restoration of ankle stability following ligament repair or reconstruction surgery, a high prevalence (13%~35%) of postoperative residual pain has been reported. This pain can negatively affect the clinical outcomes and patient satisfaction. This study examined the causes of persistent pain after surgical treatments for chronic ankle instability.

Diffuse pigmented villonodular synovitis (PVNS) involving ankle joint needs complete mass excision and total synovectomy to reduce recurrence rate, while surrounding ligaments can be easily damaged. So the concurrent ligament reconstruction should be considered for post-excisional instability in subtalar joint as well as lateral ankle joint. We describe our experience in the management of a diffuse type PVNS, invades lateral talocrural joint extended to subtalar joint and introduce a new technique of all-in-one reconstruction for anterior talofibular,calcaneofibular and cervical ligament. Our new reconstruction technique applying modified Chrisman and Snook technique is useful in stabilization for deficiencies of the ligament complexafter PVNS excisionat lateral ankle and subtalar joint.

The aim of this study was to investigate the effect of supporting surface instability to trunk and lower extremity muscle activities during bridging exercise combined with core-stabilization exercise. Thirty young healthy adults (15 males and 15 females) voluntarily participated in this study. Each subject was asked to perform bridging exercise combined with core-stabilization exercise on three different supporting surfaces (stable ground surface, the wooden balancing board, and the air cushion). The muscle activities were measured using surface electromyography (EMG) during performing exercise. To test statistical significance, one-way ANOVA with repeated measures was used with the significance level of .05. The findings of this study are summarized as follows. (1) There were significant differences in muscle activities on internal oblique, external oblique, gluteus medius, semitendinosus, biceps femoris, medial gastrocnemius and lateral gastrocnemius during exercise (p<.05). (2) The biceps femoris and lateral gastrocnemius showed significantly higher muscle activity on the wooden balancing board rather than on the ground, and semitendinosus, biceps femoris, medial gastrocnemius and lateral gastrocnemius showed significantly higher muscle activity on the air cushion rather than on the ground (p<.05). Therefore, it is concluded that muscle activities in the trunk and the lower limbs during bridging exercise combined with core-stabilization exercise was affected with instability of supporting surface. Further researches are needed to investigate the long term effect of bridging exercise on muscle activity with patient group.

Objective : Bilateral C1 lateral mass and C2 pedicle screw fixation (C1LM-C2P) is an ideal technique for correcting atlantoaxial instability (AAI). However, the inevitable situation of vertebral artery injury or unfavorable bone structure may necessitate the use of unilateral C1LM-C2P. This study compares the fusion rates of the C1 lateral mass and C2 pedicle screw in the unilateral and bilateral methods. Methods : Over five years, C1LM-C2P was performed in 25 patients with AAI in our institute. Preoperative studies including cervical X-ray, three-dimensional computed tomography (CT), CT angiogram, and magnetic resonance imaging were performed. To evaluate bony fusion, measurements of the atlanto-dental interval (ADI) and CT scans were performed in the preoperative period, immediate postoperative period, and postoperatively at 1, 3, 6, and 12 months. Results : Unilateral C1LM-C2P was performed in 11 patients (44%). The need to perform unilateral C1LM-C2P was due to anomalous course of the vertebral artery in eight patients (73%) and severe degenerative arthritis in three patients (27%). The mean ADI in the bilateral group was 2.09 mm in the immediate postoperative period and 1.75 mm in 12-months postoperatively. The mean ADI in the unilateral group was 1.82 mm in the immediate postoperative period and 1.91 mm in 12-months postoperatively. Comparison of ADI measurements showed no significant differences in either group (p=0.893), and the fusion rate was 100% in both groups. Conclusion : Although bilateral C1LM-C2P is effective for AAI from a biomechanical perspective, unilateral screw fixation is a useful alternative in patients with anatomical variations.

Purpose: To investigate the clinical features of fistulas of the ankle joints. Materials and Methods: Seven fistulas in seven patients were reviewed during Apr. 2000 to Mar. 2002, retrospectively. There are five men and two wemen. Average age was 47.7 years (range, 42-65 years). Average follow-up period was 1.4 years. There were six cystic lesions after ankle sprain and one patient with persistent discharge after excision of bursa over lateral malleolus. Results: Duration from injury to presentation was average 9.8 years. The site of preoperative swelling was mostly over the lateral malleolus in five patients. In one patient, the area of swelling was extended to the anterolateral ankle joint and in another patient there was extensive swelling from Achilles tendon to the anterolateral ankle joint. Concomitant symptoms were instability in three patients, pain and instability in three patients. Methods of surgery were simple repair in one, modified Brostrom in three, augmentation with periosteal flap in addition to modified Brostrom in two and Chrisman-Snook in addition to augmentation with periosteal flap and modified Brostrom in one. There were no recurrence of instability as well as fistula. Conclusion: We think that the fistula of the ankle joint should be included in the differential diagnosis of the cystic lesion over the lateral malleolus and the result of surgical treatment would be satisfactory in most cases.

지진 시 액상화에 의한 지반흐름은 말뚝파괴에 가장 큰 영향을 미치는 것으로 알려져 있다. 실제로 충분히 큰 정적 안전율을 갖도록 설계된 말뚝이 지진 시 좌굴에 의해 파괴되는 사례가 빈번히 발생하였다. 본 연구에서는 1-g 진동대 실험을 통해 액상화 지반에 근입된 말뚝의 좌굴에 의한 파괴거동을 분석하였다. 실험 결과, 좌굴하중에 근접한 연직하중을 받고 있는 말뚝은 지반의 액상화 발생 시 좌굴에 의해 쉽게 파괴될 수 있으며 액상화에 의한 지반흐름이 발생할 경우, 말뚝의 횡방향 변형이 증가하면서 좌굴파괴하중이 감소함을 알 수 있었다. 또한 파괴된 말뚝을 꺼내어 관찰한 결과, 액상화가 발생한 후라도 지반에 구속압이 존재하여 Euler 좌굴현상과 다르게 말뚝 하부가 아닌 중간위치에서 말뚝파괴가 발생하였으며 지반경사가 급해질수록 지반흐름에 의한 파괴 위치가 점점 말뚝하부로 낮아짐을 볼 수 있었다.
