Background: Various types of miniplates have been developed and used for the reduction of facial bone fractures. We introduced Yang's Keyhole (YK) plate, and reported on its short-term stability. The purpose of this study was to evaluate the long-term stability of the YK plate, as a follow-up study, by examining the patients who had used the YK plate among the patients with the reduction of mandible fractures and who visited for plate removal. Methods: We reviewed the medical records of 16 patients who underwent mandibular fracture fixation using a YK plate (group I) and 17 patients who underwent mandibular fracture fixation using a conventional plate (group II). Assessment was then made on malunion, occlusal stability, discomfort during the application, and clinical symptoms. Results: From January 2015 to December 2017, a total of 36 patients underwent mandibular fracture surgery using a YK plate. A total of 16 patients received plate removal. Among them, 15 were male and 1 female. The average age was 26 years. The applied surgical sites were the 12 on mandibular angle, 4 on mandibular symphysis, and 2 on subcondyle. The application period of YK plate was an average of 335 days. During the same period, 45 people underwent surgery on the conventional plate. A total of 17 patients received plate removal. Among them, 15 were male and 2 females. The average age was 36 years. The applied surgical sites were the 8 on mandibular angle, 4 on mandibular symphysis, and 2 on subcondyle. The application period of the conventional plate was an average of 349 days. No malocclusion occurred at the time of removal, and occlusion was stable. No patient complained of joint disease or discomfort. Conclusion: The YK plate system, in which the screw was first inserted and the plate was applied, for clinical convenience did not cause any particular problem and no significant difference from the conventional plate.

Purpose: Clinical reports on treatment outcomes of sternal fractures are lacking. This study details the clinical features, treatment approaches, and outcomes related to traumatic sternal fractures over a 10-year period at a single institution. Methods: A retrospective cohort study was conducted of patients admitted to a regional trauma center between January 2012 and December 2021. Among 7,918 patients with chest injuries, 266 were diagnosed with traumatic sternal fractures. Patient data were collected, including demographics, injury mechanisms, severity, associated injuries, sternal fracture characteristics, hospital stay duration, mortality, respiratory complications, and surgical details. Surgical indications encompassed emergency cases involving intrathoracic injuries, unstable fractures, severe dislocations, flail chest, malunion, and persistent high-grade pain. Results: Of 266 patients with traumatic sternal fractures, 260 were included; 98 underwent surgical treatment for sternal fractures, while 162 were managed conservatively. Surgical indications ranged from intrathoracic organ or blood vessel injuries necessitating thoracotomy to unstable fractures with severe dislocations. Factors influencing surgical treatment included flail motion and rib fracture. The median length of intensive care unit stay was 5.4 days (interquartile range [IQR], 1.5-18.0 days) for the nonsurgery group and 8.6 days (IQR, 3.3-23.6 days) for the surgery group. The median length of hospital stay was 20.9 days (IQR, 9.3-48.3 days) for the nonsurgery group and 27.5 days (IQR, 17.0 to 58.0 days) for the surgery group. The between-group differences were not statistically significant. Surgical interventions were successful, with stable bone union and minimal complications. Flail motion in the presence of rib fracture was a crucial consideration for surgical intervention. Conclusions: Surgical treatment recommendations for sternal fractures vary based on flail chest presence, displacement degree, and rib fracture. Surgery is recommended for patients with offset-type sternal fractures with rib and segmental sternal fractures. Surgical intervention led to stable bone union and minimal complications.

목적: 본 연구는 관절면을 침범한 경골 외과 골절 환자의 관절경적 정복 및 내고정술 후 임상 결과와 방사선적 결과를 분석하고자 하였다. 대상 및 방법: 2000년 3월에서 2004년 8월까지 본원 정형외과를 방문한 관절면을 침범한 경골 외과 골절 환자 중 관절경적 정복 및 내고정술을 시행한 13례를 대상으로 하였다. 정확한 골절의 양상 및 함몰의 정도를 파악하기 위하여 단순 방사선 사진 및 전산화 단층 촬영 또는 자기 공명 영상 촬영을 같이 시행하여 분석한 Schatzker 골절 분류상 전례가 제 2형에 해당하였으며, 9례에서는 골결손이 심하여 자가골 및 동종골을 이용한 골이식을 시행하였다. 평균 연령은 $48(31{\sim}66)$세였고, 평균 추시기간은 $38(13{\sim}65)$개월이었다. 동반손상은 후방 십자 인대 손상 1례, 반월상 연골 손상 4례, 내측 측부 인대 손상 2례가 관찰되었다. 방사선학적 평가는 술전, 술후 및 최종 추시시 단순 방사선 사진에서 관절면 정복의 정도를 비교하였고, 기능적 평가는 IKDC 점수와 Lysholm 점수를 후향적으로 분석하였다. 결과: 최종 추시시 단순 방사선 사진상 전례에서 관절면의 정복이 잘 유지되고 있었고, 함몰이나 골절 정복 소실, 각 변형, 부정유합 등의 합병증은 관찰되지 않았다. Lysholm 점수는 평균 $87(65{\sim}97)$점이었고, Lysholm 분류상 우수(exellent) 8례, 양호(good) 3례, 보통(fair) 1례, 불량(poor) 1례이었으며. IKDC 점수는 평균 $92(82{\sim}99)$점이었다. 결론: 경골 외과 골절시 관절경적 정복은 관절면의 정확한 정복을 얻을 수 있을 뿐만 아니라 관절경을 통한 슬관절 동반 손상의 진단 및 치료를 위한 좋은 술식으로 사료된다.

구강 악안면 영역에서 외상으로 인해 발생한 골절에 대한 치료로 관혈적 혹은 비관혈적인 골절의 정복을 시행할 수 있다. 그러나, 최적의 정복이 이루어지지 않았거나 부정 유합이 발생할 경우, 하악골과 중안모 간의 구조적 관계가 상실되어 부정교합이 일어날 수 있다. 이러한 부정교합은 외상 후 부정교합이라 정의되며 안정적인 턱관절 위치의 확보 후 악교정 수술, 교정치료, 교합 재형성 및 보철적 재건 등이 외상 후 부정교합의 치료방법으로 제시되고 있다. 안정적인 턱관절은 교합 회복 전 부정교합의 재발 및 교합 변화를 방지하기 위해 필수적이며, 중심위 및 적응된 중심위는 가장 안정적인 턱관절의 위치로 교합 회복의 시작점이다. 본 증례는 다발성 안면 골절의 정복 후, 외상 후 부정교합이 발생하여 전악 교합의 회복을 위해 중심위에서 선택적 교합 조정 및 임플란트 지지 고정성 보철물로 보철적 재건을 시행한 증례로 교합 기능적으로 양호한 결과를 얻었기에 이를 보고하고자 한다.
