Purpose: We evaluated the correlation of postoperative clinical outcomes and radiologic findings using computed tomography and simple X-ray in intra-articular calcaneal fractures. Materials and Methods: The current study is based on 41 feet, 38 patients with displaced intra-articular fracture who underwent surgical treatment with at least one year of follow-up. Evaluation of clinical outcome included American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) score, and subjective satisfaction. A simple X-ray was used in evaluation of preoperative and postoperative Gissane angle, B${\ddot{O}}$hler angle, and calcaneal fracture width. Computed tomography scan was performed for evaluation of preoperative and postoperative articular step-off and articular gap in all cases. Finally, we evaluated the correlation of the postoperative clinical outcomes and radiologic findings based on the measurement. Results: The average postoperative AOFAS score and VAS score was $84.1{\pm}8.5$ and $2.2{\pm}2.2$. Subjective satisfaction was excellent in 15 cases, good in 19 cases, and fair in seven cases. The average B${\ddot{O}}$hler angle was restored from $11.1^{\circ}$ to $24.7^{\circ}$(p<0.05), Gissane angle was changed from $121.0^{\circ}$ to $119.0^{\circ}$ (p>0.05), and the average width was restored from 45.8 to 35.0 mm (p<0.05). The average articular step-off and gap were decreased from 6.3 to 2.0 mm and from 11.1 to 4.6 mm, respectively (p<0.05). No significant correlations were observed between the clinical outcome and Gissane angle, B${\ddot{O}}$hler angle, and width, and there was no significant correlation between the clinical outcome and Sanders classification. However, postoperative articular step-off showed correlation with VAS and AOFAS score and articular gap showed correlation with VAS score. Conclusion: The clinical outcome did not show correlation with B${\ddot{O}}$hler angle and Gissane angle but did show correlation with anatomical reduction of the posterior facet joint.

Objective : Although middle cerebral artery (MCA) aneurysms are less amenable to coil embolization, an increasing number of studies support favorable endovascular treatment for them. The purpose of this study is to compare the outcomes of two different treatments (surgery versus coiling) and evaluate the benefits of surgical clipping for MCA aneurysms. Methods : Here we retrospectively analyzed the outcomes of 178 ruptured and unruptured MCA aneurysms treated in patients between September 2008 and April 2012. Parameters assessing treatment outcomes include degree of aneurysm occlusion, presence of regrowth, clinical status, and complications. Results : Among 178 MCA aneurysms, 153 were treated surgically. After a mean follow-up of 12 months, the surgery group showed a clinically significant complete occlusion rate (98%) compared with the coiling group (56%) (p<0.001). Follow-up radiologic evaluation showed a higher regrowth rate (four of 16 cases) in the coiling group than in the surgery group (one of 49 cases) (p=0.003). There was no statistically significant difference in favorable clinical outcome rate between the two groups. The procedure-related permanent morbidity and mortality rates were 2% (three of 153 cases) in the surgery group and 0% (0 of 25 cases) in the coiling group. Conclusion : Compared to endovascular treatment, surgical neck clipping for both ruptured and unruptured MCA aneurysms results in a significantly higher complete obliteration rate and less regrowth. Therefore, even in this endovascular era, we still recommend surgical clipping as the primary treatment option for MCA aneurysms rather than coil embolization.

Context: Patients diagnosed with a cancer have a life time risk of developing another de novo malignancy depending on various inherited, environmental and iatrogenic risk factors. Of late the detection of new primary has increased mainly due to refinement in both diagnostic and treatment modalities. Cancer victims are surviving longer and thus are more likely to develop a new metachronous malignancy. Aims: To report our observed trend of increase in prevalence of both synchronous and metachronous second malignant neoplasms among cancer victims and to review the relevant literature. Settings and Design: A hospital based retrospective collection of prospective data of patients diagnosed with second denovo malignancy. Materials and Method: The study was conducted over a 5 year period from July 2008 to June 2012. All patients diagnosed with a histologically proven second malignancy as per Warren Gate's criteria were included. Various details regarding sex, age at presentation, synchronous or metachronous, treatment and outcome were recorded. Conclusions: The occurrence of multiple primary malignancies is not rare. Awareness of the possibility alerts the clinician in evaluation of patients with a known malignancy presenting with unusual sites of metastasis. Individualizing the treatment according to the stages of the primaries will result in durable cancer control particularly in synchronous double malignancy.

The intracranial hemorrhage in regions remote from the site of initial operations is unusual but may present as fatal surgical complication. We report a rare case of multiple, sequential, remote intracranial hematomas after cranioplasty in a patient who did not have any prior risk factors. A 51-years-old man was transferred to the hospital after a head trauma. The brain computed tomography (CT) revealed acute subdural hemorrhage on the right hemisphere with prominent midline shifting. After performing decompressive craniectomy and hematoma removal, the patient recovered without any complications. However, the patient showed neurological deterioration immediately after cranioplasty, which was done three months after the first surgery. There was extensive hemorrhage in the posterior fossa remote from the site of the initial operation site. The brain CT taken soon after removing this hematoma evacuation displayed large epidural hematoma on the left hemisphere. This case represents posterior fossa hemorrhage after supratentorial procedure and sequential delayed hematoma on the contralateral supratentorial region thus seems very rare surgical complications. Despite several possible pathogenetic mechanisms for such remote hematomas, there are usually no clear cut relationships with each case as in our patient. However, for the successful outcome, prompt evaluation and intensive management seem mandatory.

Purpose: To report the postoperative Clinical and Radiological outcomes following distal femoral fractures in elderly patients compared with young patients. Methods: From March, 1996 to March, 2012, 83 patients who received surgical treatment for fractures of the distal femur were enrolled in this retrospective study. Ages more than 65 was named group A. Group A was 49 cases and mean age is 72.5 year(65~91year). Group B was 49 cases and mean age is 45.7 year(16~61 year). Surgical methods are retrograde IM nail, locking compression plate, cannulated screw and postoperative rehabilitation is no difference between two groups. Clinical results were evaluated using Neer scores, radiographic results and the presence of clinical complications. Results: The mean union period was 18.4(12-40) weeks in group A and 17(10-24) weeks in group B. Neer functional scores are no significant statistical difference between two groups. There are 5 cases metal breakage in group A and 1case in group B. There are 3 cases nonunion in group A and 1 case in group B. Conclusion: In the case of fractures of the distal femur in elderly patients, locking plate using minimally invasive percutaneous periosteal osteosynthesis (MIPPO) technique may be one of the most effective methods and preoperative bone stock evaluation in important.

Impalement injury is the subset of penetrating trauma, defined as fixed, elongated objects penetrate and remain in the human body cavity or region by relatively low velocity. We report an unusual case of facial and neck impalement where two dirty rusted iron bars penetrated forehead bilaterally and exited neck and ear respectively without causing major organ injuries. After thorough radiologic and physical evaluation, the patient got medical and surgical treatment. The patient was discharged without complication after four day of delayed wound closure. There have been no complications and sequelaes related with trauma, wound infection and scar contracture at 3-year follow-up. According to affected organs and pattern of impalement, individualized and multidisciplinary surgical approach should be considered. Following these guidelines as in this case, it was possible to achieve excellent clinical outcome in impalement injury.

It is well established that cancer patients are more susceptible to infection because of the immunosuppressive status caused by both disease itself and anticancer treatment, including surgery and chemoradiation. Head and neck cancer (HNC) patients are generally at high-risk for coronavirus disease 2019 (COVID-19) infection and serious adverse outcomes. Although there is an urgent need for guidance in the delivery of safe, quality oncologic care, no international consented recommendation addressed the management of HNC patients in COVID-19 due to limited data. In this review, we summarized the consideration for head and neck oncologic care in the context of the COVID-19 pandemic, based on the data and the very recent recommendations from the Korean Cancer Association and National Cancer Center. COVID-19 should be taken into consideration in the comprehensive management of HNC patients, and multidisciplinary evaluation of multilevel surgical-risks, discussion of optimized strategy, and shared-decision-making with the patient are needed to maximize both the safety from infectious pandemic and outcome of surgical and oncologic care.

Eleven shoulders (9 patients) with refractory scapulothoracic dysfunction were treated with scapulothoracic arthrodesis between 2000 and 2006. Refractory shoulder dysfunction included facioscapulohumeral muscular dystrophy in five shoulders (3 patients), refractory scapular winging with long thoracic nerve palsy in one shoulder, scapular winging caused by serratus anterior palsy with trapezius dysfunction in one shoulder, post-surgical thoracic outlet syndrome due to medial clavicle resection in two shoulders, refractory scapular winging with spinal accessory nerve injury in one shoulder, and chronic trapezius rupture caused by cervical spine surgery in one shoulder. The mean active flexion was improved from 82 degrees preoperatively to 112 degrees postoperatively. The mean Constant score was improved from 27.2 points to 68.0 points. Two shoulders (1 patient) that had facioscapulohumeral muscular dystrophy had broken wires due to nonunion, and one patient had a reactive pulmonary effusion. In ten of the eleven shoulders, the patients were satisfied with their results. The scapulothoracic arthrodesis can cause significant pain relief and functional improvement in refractory scapulothoracic and/or shoulder dysfunction. By selecting patients that present with appropriate indications, and using experienced surgical technique through complete preoperative evaluation, we can diminish the complication rate and make good clinical outcomes.

Laryngeal trauma is an uncommon injury but can be life-threatening event. So, early diagnosis is important for appropriate surgical management and better outcome. Because there have been some controversies about Initial airway management, appropriate diagnostic evaluation, operative indication and timing, operative technique, it is difficult to make a common management pathway in laryngeal trauma. A case of laryngeal trauma with thyroid cartilage and hyoid bone fracture is presented with a brief review of literature.
