Background: In a frontal sinus reconstruction, the literature primarily recommends a surgical approach for definite treatment with the exception of for anterior wall fractures with no dislocation. Many studies have assessed a range of methods for the reduction of frontal sinus fractures. This paper presents a case, in whom the anterior wall of the frontal sinus was reconstructed using an outer table calvarial bone graft in an en bloc manner. Patient and methods: A 36-year-old male visited the emergency room with a heavy injury to the forehead. He was diagnosed with fractures of the anterior and posterior wall of the frontal sinus. The neurosurgeon removed the fractured area and repaired the meninges. Afterwards, cranialization was performed and the opening of the nasofrontal duct was obstructed. After fixing the removed bone to its original location, all fragments of fractured anterior wall were purged out and the anterior wall reconstructed using an en bloc calvarial bone graft. Results: In the post-operative 8 months period, there were no complications, the round contour of the forehead was expressed well and the patient was satisfied with the result. Conclusion: There are many methods for reconstructing the anterior wall of the frontal sinus. On the other hand, in cases of large fracture sites with many fractured bone fragments, en bloc harvesting of the outer table calvarial bone could be a better choice than making use of only plates and screws because this method shows a good results in terms of aesthetics with a low complication rate.

A case of traumatic spondyloptosis of the cervical spine at the C6-C7 level is reported. The patient was treated succesfully with a anterior-posterior combined approach and decompression. The patient had good neurological outcome after surgery. A-51-year-old female patient was transported to our hospital's emergency department after a vehicle accident. The patient was quadriparetic (Asia D, MRC power 4/5) with severe neck pain. Plain radiographs, computerize tomography and spinal magnetic resonance imaging (MRI) showed C6-7 spondyloptosis and C5, C6 posterior element fractures. Gardner-Wells skeleton traction was applied. Spinal alignment was reachived by traction and dislocation was decreased to a grade 1 spondylolisthesis. Then the patient was firstly operated by anterior approach. Anterior stabilization and fusion was firstly achieved. Seven days after first operation the patient was operated by a posterior approach. The posterior stabilization and fusion was achieved. Postoperative lateral X-rays and three-dimensional computed tomography showed the physiological realignment and the correct screw placements. The patient's quadriparesis was improved significantly. Subaxial cervical spondyloptosis is a relatively rare clinical entity. In this report we present a summary of the clinical presentation, the surgical technique and outcome of this rarely seen spinal disorder.

Congenital deficiency of the anterior cruciate ligament (ACL) is a rare disorder that has been reported in association with other knee dysplasia like as congenital knee dislocation. congenital short femur, congenital absence of menisci, congenital ring meniscus, and thrombocytopenia-absent radius syndrome. There has been no published explanation about the etiology of bilaeral ACL deficiencies without other abnomality. The patient of congenital ACL deficiency must be carefully inspected about combined anomaly. Those efforts may be helful in treatment or ACL deficient patients and evaluation of pathophysiology or ACL deficiency. However there has not been a ruptured congenital deficiency of the ACL without other dysplasia or the knee and other congenital skeletal abnomalities. We reported a case of symptomatic bilateral congenital deficiencies of the ACL which have not been associated with other skeletal abnormalities.

Purpose: Cervical dislocations with locked facets account for more than 50% of all cervical injuries. Thus, investigating a suitable management of cervical locked facets is important. This study examined factors of close reduction failure in traumatically locked facets of the subaxial cervical spine patients to determine suitable surgical management. Methods: We retrospectively analyzed of the case histories of 28 patients with unilateral/bilateral cervical locked facets from Nov. 2004 to Dec. 2010. Based on MRI evaluation of disc status at the injury level, we found unilateral dislocations in 9 cases, and bilateral dislocations in 19 cases, The patients were investigated for neurologic recovery, closed reduction rate, factors of the close reduction barrier, fusion rate and period, spinal alignment, and complications. Results: The closed reduction failed in 23(82%) patients. Disc herniation was an obstacle to closed reduction (p=0.015) and was more frequent in cases involving a unilateral dislocation (p=0.041). The pedicle or facet fracture was another factor, although some patients showed aggravation of neurologic symptoms, most patients had improved by the last follow up. The kyphotic angle were statistically significant (p=0.043). Sixs patient underwent anterior decompression/fusion, and 15 patients underwent circumferential fusion, and 7 patients underwent posterior fusion. All patients were fused at 3 months after surgery. The complications were 1 case of CSF leakage and 1 case of esphageal fistula, 1 case of infection. Conclusion: We recommend closed reduction be performed as soon as possible after injury to maximize the potential for neurological recovery. Patients fot whom closed reduction of the cervical locked facets have a higher incidence of anatomic obstacles to reduction, including facet fractures and disc herniation. Immediate direct open anterior reduction or circumferential fixation/fusion of locked cervical facets is recommended as a treatment of choice for traumatic locked cervical facet patients after closed reduction failure.

폐구성 과두 걸림이라고도 하는 비정복성 관절원판변위는 관절원판이 과두로부터 전위되어 과두 운동 시에 정상위치로 되돌아가지 않는 임상상태를 말한다. 비정복성 관절원판변위가 급성으로 나타난 경우에는 초기 치료에서 수조작에 의한 관절원판의 정복을 시도하여야 한다. 일반적으로 과두 걸림 발생 후 1주일 이내에 수조작술을 시행하는 경우에는 대개 성공적으로 관절원판이 정복되는 경우가 많지만 그 이상 경과된 경우에는 성공률이 떨어지는 것으로 알려져 있다. 수조작술을 통해 관절원판의 정복이 일어난 이후에는 전방위치 교합장치를 즉시 장착시켜서 폐구성 과두 걸림이 다시 발생하지 않도록 하는 것이 좋다. 하지만 전방위치장치를 제작하는데 시간이 많이 소요되므로 임상에서 즉시 제작하여 장착하기는 현실적으로 어려운 경우가 많다. 또한 전방위치장치를 제작하기 전까지 자가 중합 아크릴릭 레진을 이용한 임시 전방위치 장치를 제작하여 사용하는 방법도 레진의 냄새로 인한 불편감 및 시간 소요 등으로 널리 이용되고 있지는 않다. 또한 레진 알러지가 있거나 교정 치료 중이어서 레진을 사용하기 어려운 경우, 또는 행동조절이 불가능한 일부 환자들에게는 이 장치를 적용하기 어렵다. 따라서, 수조작술을 통해 관절원판이 정복된 경우 레진 대신 퍼티 고무 인상재를 이용하여 임시 전방장치를 제작한 후 단기간 적용하여 폐구성 과두 걸림을 치료한 증례를 통해 그 효용성을 확인해 보고자 하였다.

Purpose : We evaluated clinical result of arthroscopic and open Bankart repair in anterior shoulder instability to identify factors iuluencing operative result and prognosis. Materials & Methods . We reviewed 24 patients of anterior shoulder instability treated with arthroscopic Bankart repair in 16 cases and open Bankart repair in 8 cases. Average age was 26 years old and involved in dominant arm in 15 cases. Patients were suffered instability for 3.1 years before operation and mean follow-up was 2 year 9 months ( 1 you 9 months -4year 10 months). Results : Post operative pain was subsided in 2 weeks in arthroscopic surgery and 3 weeks in open surgery. The final range of motion after arthroscopic repair were flekion in 168" , external rotation in 54" , and internal rotation in 79, and after open repair 168" ,49" , and 78 respectively. In arthroscopic surgery,2 cases (13%) were redislocated, and 4 cases(25%) showed mild instability. In open case,1 case (11%) showed mild instability. According to function- al result by Rowe grading scale, satisfactory results were 12case (76%) in arthroscopic repair and 7 cases (88%) in open cases. Conclusions Both arthroscopic or open Bankart could get good results in the treatment of anterior instability of shoulder. In arthroscopic repair, perioperative morbidity was lower than open repair, but it needs careful rehabilitation program to prevent redislocation and to return to sports activity.

There are some patients who have traumatic anterior shoulder instability due to minor injuries like overhead activities. The purpose of this study was to clarify characteristic features of traumatic anterior shoulder instability due to minor injuries. According to the mechanism of injury in an initial dislocation, 83 shoulders that underwent the stabilizing surgery for traumatic anterior shoulder instability were divided into two groups. Traumatic group included patients who suffered from a fall or a direct injury. Minor injury group included patients who suffered from the other injury like overhead activity. General joint laxity, range of motion and laxity under anesthesia, and intraarticular findings were compared between two groups. The morphology of superior and middle glenohumeral ligaments, Bankart lesion, Hill-Sachs lesion, and partial articular surface tendon avulsion lesion were observed in arthroscopy. Minor injury group consisted of 19 shoulders with 8 males, 11 females and the mean age of 22.5 years. Traumatic group consisted of 64 shoulders with 52 males, 7 females and the mean age of 24.3 years. Female in minor injury group was significantly more than that in traumatic group. There was no difference in general joint laxity and intraarticular findings between two groups. Range of external rotation in injured side in minor injury group was significantly more than that in traumatic group. Inferior laxity in both sides in minor injury group was more than that in traumatic group. In conclusion, the traumatic anterior shoulder instability due to minor injuries might incline to occur the shoulder in female and with inferior laxity of shoulder.

목적: 견관절 전방탈구 후 Bankart 병변이 있었던 환자의 자기공명관절조영술 (MRA)에서 Hill-Sachs (HS) 병변의 유무와 정도를 평가하고, 이를 관절경에서 보인 Bankart 병변의 크기와 탈구 빈도와 비교하고자 하였다. 대상과 방법: 견관절 전방탈구 후 발생한 Bankart 병변의 관절경 수술을 시행 받은 86명의 MRA를 분석하였다. MRA에서 HS 병변의 가장 큰 표면길이와, 관절경에서 보인 Bankart 병변의 크기를 측정하였다. HS 병변 길이와 Bankart 병변 크기, 탈구 빈도 사이의 상관성을 분석하였다. 결과: HS 병변은 78명에서 관찰되었다. HS 병변의 가장 긴 표면길이는 평균 18.8 mm (9.3 - 29.6 mm) 였고, Bankart 병변은 평균 4.25시계구간 크기 (1-6시계구간 크기) 였다. 3명은 단일탈구, 75명은 재발탈구였다. HS 병변의 크기는 Bankart 병변의 크기와 유의한 양의 상관관계를 보였고 (p = 0.001, r = 0.37), 탈구 빈도와는 관련성이 없었다. 결론: HS 병변은 Bankart 병변이 있는 환자에서 흔하게 발견되었다. HS 병변과 Bankart 병변의 크기와 유의한 양의 상관관계를 보였다.

비외상성의 수정체 이탈 환자에서 윤부 수정체절제술을 시행하는 경우, 초음파유화술 후 수정체낭 겸자를 이용하여 수정체낭을 모두 제거하고 앞유리체절제술을 시행하는 경우와 시행하지 않는 경우에 따라 시력예후 및 술후 합병증 발생에 미치는 영향에 대해 알아보고자 20명(33안)의 환자를 대상으로 술전 및 술후 합병증 발생에 대해 통계적으로 분석하였다. 앞유리체절제술을 시행한 I군(18명, 27안)과 앞유리체절제술을 시행하지 않은 II군(5명, 6안)으로 나누었으며, 술 후 두 줄 이상의 시력의 호전이 있는 경우를 호전의 지표로 삼았다. 술전과 비교하여 술후에 시력 호전이 있었던 경우가 I군은 27안 모두에서, II군은 6안중 5안에서 있었으나 두 군간에 유의한 차이는 없었다(p>0.05). 술후 합병증은 I군에서 인공수정체의 이탈이 4안(14.8%), 유리체 출혈이 2안(7.4%), 안내염이 1안(3.7%)에서 발생하였으며, II군에서 유리체 탈출이 1안(16.7%), 안압상승이 1안(16.7%)에서 발생하였으나, 두 군 모두에서 가장 시력을 위협하는 합병증인 망막박리는 발생하지 않았다. 비외상성 수정체 이탈의 치료로 수술적 치료의 적응증에 해당하는 경우 윤부 수정체절제술과 인공수정체 공막고정술을 시행하면 수술결과와 술후 합병증 면에서 좋은 수술술기가 될 것으로 사료되며, 앞유리체절제술은 유리체 탈출 등이 없다면 반드시 시행하지 않아도 수술결과에 영향을 주지 않을 것으로 생각된다.
