Supernumerary ectopic limb(s) (SEL) is a congenital anomaly defined as the presence of accessory limb(s) attached to various body regions. This paper describes a case of SEL with ectopic lung and ectopia cordis in a newborn calf, based on macroscopic, microscopic and radiographic findings. External features of multiple congenital anomalies included an ectopic lung growing over the middle of the backbone and covered with normal haired skin. Ectopia cordis was found in the abdominal cavity and attached to the liver. Two extra abnormal limbs originated separately from within the ectopic lung. Most of the abdominal organs were exposed to the outside through the opened abdominal cavity. Microscopically the ectopic lung tissue had edema in the connective tissue around the bronchus and artery. Changes in other organs included congestion of the renal medulla, infiltration of inflammatory cells (lymphocytes and eosinophils) around the hepatic portal tract, and edema surrounding blood vessels and neurons in the brain. The rudimentary humerus of the forelimb was attached to the thoracic spine, as viewed radiographically. The hindlimb was consisted of an irregularly shaped femur, short tibia and fibula, two tarsal bones, one metatarsal bone, and three phalanges. This is the first description of congenital anomalies involving the SEL, ectopic lung and ectopia cordis in a calf.

Osteosarcoma is the most common primary bony malignancy and its survivorship has been progressed markedly through refined chemotherapy and surgery. But still there are many non-responders and analysis of prognostic factors may be helpful for them. Two hundred and sixty-six patients were enlisted between Mar, 1985 and Sep. 1994. Among them our inclusion criteria were: 1)primary, nonmetastatic classical osteosarcoma 2)extremity in location 3)no prior treatment at other institute and completed neoadjuvant chemotherapy and surgery according to our protocol. One hundred and eleven cases were eligible. Analyzed factors were:age, sex, location, tumor size, and pathologic response. Statistical methods were log-rank test for univariate and Cox's test for multivariate analysis. Male to female ratio was 69:42 with an average age of 17.2 years. Locations of tumor were distal femur 59, proximal tibia 29, and proximal humerus 8. Tumor size were measured by its maximal diameter and 48 cases were above 10cm and 47 cases were below 10cm. For pathologic response, 57 cases showed more than 90% and 54 cases were less than that. Limb salvage procedure was 101 cases and amputation was 10 cases and their local recurrence rate were 3.6%. Average follow-up period was 24(9-78.2) months and their final status was CDF 86, AWD 8, NED 5, and DOD 12 cases. In univariate study: type of operation(p=0.005), tumor size(p=0.005), and pathologic response(p=0.02) were significant variables. Pathologic response(p=0.03) and type of operation(p=0.01) were meaningful prognostic factors on multivariate analysis. But the latter result was interpreted as a bias, so pathologic response remained as a sole meaningful prognostic factor. More aggressive chemotherapy will be needed to improve the survival.

Background: The purpose of this study was to evaluate the usefulness and safety of the anterosuperior deltoid splitting approach for fixation of displaced proximal humeral fractures by analyzing the surgical outcomes. Methods: Twenty-three patients who could be followed-up for at least 8 months after the treatment of displaced proximal humeral fractures through the anterosuperior deltoid splitting approach were enrolled. We evaluated the reduction of the fractures and surgery-related complications at the last follow-up using X-ray results and clinical outcomes comprising the University of California at Los Angeles (UCLA) scoring system and the Korean Shoulder Society (KSS) score. Results: At the last follow-up of patients treated using the anterosuperior deltoid splitting approach for internal fixation of proximal humeral fractures, we found 22 cases (95.6%) of bone union, a mean UCLA score of 28.3 (range, 15 to 34) and a mean KSS score of 82.1 (range, 67 to 95). Various surgery-related complications were noted; a case of varus malunion after fracture displacement, a case of nonunion, a case of delayed union, two cases of impingement, and a case of partial axillary nerve injury, which recovered completely through the follow-up. Conclusions: Plate fixation using the anterosuperior deltoid splitting approach could be another reliable option for treating displaced proximal humeral fractures.

Background: This retrospective comparative study aims to evaluate the surgical outcomes and complications of two surgical methods for simple fractures of the humeral shaft; minimally invasive anterior plating and open reduction combined with internal fixation. Methods: A total of 26 patients with humeral shaft simple fractures, who had surgery between June 2009 and September 2013 and were followed-up at least 12 months, were included in our analysis. They were divided into two groups; group 1 comprised of 12 patients who underwent minimally invasive anterior plating and group 2 comprised of 14 patients who underwent an open reduction and internal fixation. The clinical outcomes, radiological results, and complications were compared and analyzed. Results: We found that bone union was achieved in all patients, and the mean union periods were $20.7{\pm}3.34$ and $20.3{\pm}3.91$ weeks for groups 1 and 2, respectively. In most patients, we found that shoulder and elbow functions were recovered. At 12 months post-operation, we found that the Korean Shoulder Scoring system, the University of California at Los Angeles score and Mayo elbow performance score were $91.4{\pm}7.97$, $33.4{\pm}1.15$, and $90.8{\pm}2.23$ for group 1, and $95.2{\pm}1.53$, $33.3{\pm}1.43$, and $90.17{\pm}1.85$ for group 2. In terms of complications, we found that 2 patients had radial nerve palsy after open reduction and internal fixation, but all cases spontaneously resolved within 6 months. Complications such as infection and loss of fixation were not reported. Conclusions: Both minimally invasive anterior plating and open reduction with internal fixation produced satisfactory outcomes in the treatment of simple fractures of the humeral shaft.

Background: The aim of this study was to assess the clinical outcomes after treatment of proximal humeral fractures with locking plates, and to determine which factors influence the clinical and radiological outcomes. Methods: Fifty six patients who were treated with locking plates for proximal humeral fractures and had been followed for more than 1 year were enrolled in this study. We performed functional evaluation using the Constant score and analyzed radiographic results. The following factors that may potentially influence the clinical outcomes were assessed: age, gender, type of fracture, presence of medial metaphyseal comminution, bone mineral density, anatomical reduction, restoration of medial mechanical support, and postoperative complications. Results: The mean Constant score was 70.1 points at the final follow-up. Female gender, 4-part fractures, AO type-C fractures, and fractures with medial metaphyseal comminution were associated with a poor clinical outcome. On the other hand, restoration of medial mechanical support and accurate anatomical reduction had a positive influence on clinical outcomes. Postoperative complications resulted in 3 patients (intra-articular screw perforation: 1 patient, varus deformity with screw loosening: 1 patient, nonunion: 1 patient). Conclusions: When treating proximal humeral fractures with locking plate fixation, following factors: a female gender, Neer type 4-part fracture, AO type C fracture, and medial metaphyseal comminution are important risk factors that surgeons should take into consideration. Factors that contribute to better clinical outcomes of operative treatment for humeral fractures are accurate anatomical reduction and restoration of medial mechanical support.

Background: Gunshot-related fractures near the elbow are challenging, and available data to guide the practitioner are lacking. This report analyzes injury patterns and treatment strategies in a case series from a high-volume urban trauma center. Methods: All periarticular gunshot fractures near the elbow treated at a level 1 trauma center from 2014 to 2018 were retrospectively reviewed. Fracture location, patient demographics, concomitant injuries, treatment modalities, and complications were analyzed. Results: Twenty-four patients were identified. All patients received prophylactic antibiotics upon admission and underwent urgent surgical debridement. Open reduction and internal fixation (ORIF) was performed with initial debridement in 22 of 24 patients. Seven patients sustained distal humerus fractures, 10 patients sustained isolated proximal ulna or proximal radius fractures, and seven had combined fracture patterns. Eleven patients presented with nerve palsy, and two had transected nerves. Two patients had vascular injury requiring repair. One patient required a temporary elbow-spanning external fixator and underwent staged debridement followed by ORIF. One patient with a grade IIIC fracture developed a deep infection that precluded ORIF. One patient required revision ORIF due to fracture displacement. Conclusions: This investigation reports on management of ballistic fractures near the elbow at a busy urban level I trauma center. Our management centered on rapid debridement, early definitive fixation, and intravenous antibiotic administration. We report on associated neurovascular injury, bone loss, and other challenges in this patient population. Level of evidence: IV.

목적: 상완골 근위부 절제 후 다양한 재건술이 시도되었으나 역 견관절 전치환술의 도입으로 기능적 결과의 향상이 있었다. 그러나 광범위한 골결손을 동반한 경우에도 이 방법을 적용할 수 있는지와 비수술적 치료 실패 후 지연 재건하면 기능회복의 정도가 어떤지에 대해서는 불확실하다. 대상 및 방법: 상완골 근위부 재건술 후 실패한 11예는 중첩 동종골과 역 견관절 전치환술의 조합술을, 비수술적 치료가 실패한 6예는 지연 역 견관절 전치환술을 시행하였다. 수술 전, 후 기능적 결과를 비교하였으며 합병증을 기술하였다. 결과: 역 견관절 전치환술과 동종골 조합술로 일차 수술이 실패한 11예 전부에서 안정된 재건술이 가능하였으며 수술 전 주 증상도 해소되었다. 골 접합부 평균 골유합 기간은 5.5개월이었다. 수술 전, 후 근골격계 기능 점수는 평균 20.3점에서 25.7점으로 증가하였다. 일차 수술 후 4년 이내에 역 견관절 전치환술로 치환한 6예 중 4예에서 $90^{\circ}$ 이상의 상지 거상이 가능하였으며, 일차 수술 후 4년 이후에 수술한 5예는 견관절의 안정성은 얻었으나 전부 $90^{\circ}$ 이상 거상이 불가능하였다. 합병증은 관절탈구와 무균성 감염이 각각 1예로 폴리에틸렌 교체와 반흔 조직 절제술로 치료하였다. 비수술적 치료 실패로 지연 역 견관절 전치환술을 한 6예에서 기능평가 점수는 향상되었으나 전 예에서 상지의 $90^{\circ}$ 이상 거상은 불가능하였다. 결론: 중첩 동종골과 역 견관절 전치환술의 조합술은 대량의 상완골 골결손이 발생한 환자에서 간단하고 합병증이 적은 골질 회복방법으로 생각된다. 진단 시 근위 상완골 전 절제가 필요한 전이성 골종양 환자는 조기에 역 견관절 전치환술을 하는 것이 기능유지에 도움이 될 것으로 생각된다.

기괴 방골성 골연골성 증식증은 발생 빈도가 드물고 재발 빈도가 높은 양성 골 병변으로 1983년 Nora등에 의해 처음으로 기술되었다. 처음에는 수족지골에만 발생하는 것으로 보고 되었으나 이후 장골과 두개골 및 상악골 등에서 발생한 예가 보고 되었으며 특히 장골에 발생한 경우 악성 종양과의 감별이 중요하다. 본 증례는 14세 남자환자의 상완골 간부에 발생한 기괴 방골성 골연골성 증식증의 예로 단순 방사선 사진 상 상완골 간부에 비교적 광범위한 기저부를 가지면서 피질골에 붙어있는 약 $4{\times}3$ cm 크기의 원형의 석회화된 종물 소견을 보였으며, 조직학적으로 고밀도의 연골성 증식과 함께 거기서 성숙해나가는 망상골, 그리고 골소주 주변에서는 섬유성 기질이 관찰되었다. 기괴 방골성 골연골성 증식증은 비교적 드문 질환이나 재발이 흔하고 악성 병변과 혼동 될 수 있는 조직학적 특징을 나타내며 단순 절제술로 치료한다. 저자들은 장골에서는 매우 드물게 발생하는 비교적 빠른 성장 속도를 가진 상완골 간부의 기괴 방골성 골연골성 증식증을 경험하였기에 이를 문헌적 고찰과 함께 보고하는 바이다.
