Purpose: The purpose of this study was to evaluate the clinical results of anatomic reduction of bony mallet finger using modified-intrafocal pinning technique. Methods: From March 2014 to October 2017, 18 patients with bony mallet finger were treated with modified-intrafocal pinning technique. Kirschner-wire was used to directly reduction the bony fragment, and extension block pinning and distal interphalangeal joint fixation were additionally performed to minimize the loss of reduction. Postoperative pain, range of motion, and radiological evaluation were performed. Duration of bone healing, functional recovery and complication rate were evaluated and Crawford's criteria was used to determine functional outcome after surgery. Results: Bone union was achieved in all cases after a postoperative mean of 6 weeks (5-7 weeks). An average of $2.8^{\circ}$ ($0^{\circ}-10^{\circ}$) extension loss occurred in all patients. All patients showed satisfactory joint congruency and reformation of the joint surface, the mean flexion angle of the distal interphalangeal joint at the final follow-up was $72.2^{\circ}$ ($70^{\circ}-75^{\circ}$). According to Crawford's classification, 12 patients (66.7%) were excellent and 6 patients (33.3%) were good. Conclusion: Modified-intrafocal pinning technique is a method of obtaining anatomical bone healing by directly reduction and fixation of the bony fragment. Combined with other conventional percutaneous pinning procedures, it is expected that good results can be obtained if applied to appropriate indications.

Purpose: To compare clinical outcome of Sanders type IV intra-articular calcaneal fracture treated with open reduction and internal fixation (ORIF) versus ORIF and primary subtalar arthrodesis (PSTA). Materials and Methods: Between March 2003 and November 2013, 22 patients with 22 Sanders type 4 intra-articular calcaneal fractures were included in this study. Of these, 11 were treated with ORIF (ORIF group), and 11 were treated with ORIF and PSTA (PSTA group). The mean follow-up period was 34.6 months (range, 18-72 months). Clinical outcomes were assessed along with the American Orthopedic Foot and Ankle Society's ankle-hindfoot scale (AOFAS score), and the visual analogue scale pain score (VAS score) at 6-month, 12-month, and last follow-up. Patient satisfaction, return to previous occupation and postoperative complications were also investigated. Results: The results for ORIF did not differ from those for PSTA based on the last follow-up AOFAS scores or the VAS scores (p>0.05). However, patient satisfaction was significantly higher in the PSTA group (p=0.008). Secondary subtalar arthrodesis was conducted in five patients (45.5%) of the ORIF group within 2 years postoperatively. Conclusion: We were unable to demonstrate a significant difference in clinical outcomes between ORIF and PSTA; however, the patient satisfaction was higher in the PSTA group. PSTA may be a suitable choice for patients who need fast recovery to daily activity and to prevent the need for secondary subtalar arthrodesis.

전방십자인대 재건술시 자가건 선택에 대해서는 많은 논쟁의 소지가 존재하며 많은 보고들이 나오고 있으나, 현 시점에서 이식건으로써 자가 골-슬개건-골이 표준(gold standard)라는 주장은 이제 변화하고 있으며, 골-건 고정방법의 개선에 따른 조기 슬관절 안정성의 호전으로 자가 슬괵건의 사용이 점점 증가되고 있는 추세이다. 자가 골-슬개건-골은 이식건으로써 강한 물성, 튼튼한 고정, 장기 추시에서 높은 성공률 등으로 젊고, 강한 활동을 요하는 운동선수에서 종종 선택되고 있으며 조기에 강한 활동으로의 운동 복귀를 할 수 있다. 그러나 슬관절 전방 통증, 무릎을 꿇을 때의 통증, 슬개골골절, 슬개-대퇴 관절의 염발음 및 대퇴사두근력의 감소 등 이식물 채취로 인한 공여부 이환이 문제가 되었다. 그래서 자가 골-슬개건-골의 이식건으로서의 문제점 및 문헌상 고찰을 하여 논하고자 한다.

Purpose: We wanted to review the arthroscopic Remplissage technique and introduce our experiences with it for treating recurrent shoulder instability with a large Hill-Sachs lesion. Materials and Methods: The arthroscopic Remplissage technique with Bankart repair is performed in patients with no osteoarthritis, no fracture around the shoulder, a history of recurrence more than 10 times, a large Hill-Sachs lesion more than 30 to 40% of the humeral articular surface and glenoid bone loss less than 20%. Results and Conclusion: For recurrent shoulder instability with a large Hill-Sachs lesion, the Remplissage technique resulted in a good outcome for the shoulder stability, and good clinical and functional results.

Coracoid impingement syndrome results from abnormal contact between the anterosuperior humerus and the coracoacromial arch. The coracoid impingement may occur from traumatic, idiopathic, or iatrogenic causes. Traumatic causes of coracoid impingement include fractures of scapular neck, coracoid process or lesser tuberosity. Coracoid impingement due to lesser tuberosity malunion is a rare disease and most of them were treated by open procedures. The authors present a case of coracoid impingement caused by malunion after isolated lesser tuberosity fracture which was treated by arthroscopic coracoplasty with percutaneous screw fixation.

79 surgically managed mandibular condylar fracture patients included the 25 patients treated with Dr, Nam's method were analysed the postoperative resluts in Oral and Maxillofcial Surgery, School of Dentistry, Wonkwang University since 1993 to 1995. Mean patient's age is 32.5 years (range, 8 to 65 years), and follow-up periods were a minimum of 3 months to 28 months. 19% condylar fractures were associated with mostly symphysis portion. According to the patient's age, severity of condylar fractures, clinical signs and symptoms, radiographic findings, treatmenet plans had been performed. Rigid fixation have performed greatly, and then fragment removal of fractured mesial pole of proximal segment of the condylar and little cases of reshaping and eminoplasty and lag screw have been applied. Two cases of the both condylar resorption and deviated condyle posteriorly in Dr. Nam's method. None of infection or necrosis signs of treated condyle surgically. In my opinion, whenever possible, displaced condylar fracture can be managed surgically with rigid fixation, but not Dr. Nam's method. Usually if perform the surgical management of condylar fractures you should maintain maxillomandibular fixation for 2 weeks, or more and has to follow-up functional mandibular exercise should be kept continuously.

Purpose: We report case of neglected elbow dislocation for three years. Material and method: A 45 years old female patient presented with neglected elbow dislocation for three years. Since the patient had contracture in both lateral and medial collateral ligament of elbow, dissection was done. After total separation of posterior articular capsule and incision of anterior articular capsule, by manual manipulation, reduction of radiohumeral and ulnohumeral joints were obtained. We applied modified Morrey type hinged external fixation in the elbow and done early elbow exercise. Result and Conclusion: Since we have experienced a satisfactory result in the case with neglected elbow dislocation for 3 years by using open reduction and hinged external fixation, we report it with the literature.

When an ankle lateral malleolar fracture is accompanied by a deltoid ligament rupture without a medial malleolar fracture, such an injury is called a bimalleolar equivalent fracture. This means that even if there is no bony injury on the medial side, there may be functional instability of the ankle joint due to damage to the deltoid ligament. Manual or gravity external rotational stress radiography is used to differentiate an ankle bimalleolar equivalent fracture from an isolated lateral malleolar fracture. If the medial joint gap is widened on the stress radiography, the deltoid ligament injury can be diagnosed, and surgical treatment for fibula fractures is recommended. After open reduction of the fibula fracture (with syndesmotic fixation if needed), a decision on the repair of the deltoid ligament is taken depending on the surgeons' preference and intraoperative findings. The deltoid ligament repair is performed by inserting a suture anchor (or anchors) in the medial malleolus and fixing the deep and superficial deltoid ligaments to the medial malleolus. The only randomized study to evaluate the utility of deltoid ligament sutures in ankle fractures did not support the deltoid ligament suture, but the study itself had many limitations. An appropriately powered, randomized, controlled trial of the deltoid ligament repair with both patient-reported outcome and radiographic outcome evaluation is needed in the future.

동종 반월상 연골 이식술은 불가피하게 반월상 연골이 소실된 환자에서 증상을 호전을 위한 매우 효과적인 치료이다. 관절연골의 보호 효과 등 장기적인 결과에 대해서는 아직까지는 많은 연구가 필요한 상태이지만, 이러한 환자에서 반월상 연골의 기능을 회복시키기 대안이 많아 점차 널리 시행되는 추세이다. 이식된 반월상 연골이 제 기능을 하기 위해서는 적절한 수술방법을 통하여 반월상 연골 이식물을 정확한 위치에 이식을 하는 것은 필수적일 것이다. 여러 저자들 마다 서로 다른 다양한 반월상 연골 이식술의 방법들을 사용하고 있지만, 어떤 방법을 선택하던지 간에 이식된 반월상 연골의 전각 및 후각을 해부학적인 위치에 견고하게 고정을 하는 것이 매우 중요하다. 술자의 선호도에 따라 다양한 방법중의 하나를 선택을 할 수 있지만, 어떤 방법이든 수술 술기상의 어려움이 있으므로, 철저한 준비와 노력이 필요할 것이다. 본 종설에서는 반월상 연골 이식술 중 개방적 방법에 대한 간단한 소개와 함께 저자들이 사용하는 관절경을 이용한 수술방법을 정리하였다.
