There are many methods of making cement spacer in patients who require a two-staged operation for humeral head osteomyelitis. However, limitation of motion after the first surgery-due to inadequate size and insufficient intra-articular space for second surgery-remain to be an issue. To mitigate this issue, we made a cement spacer with the same size and shape of the patient humeral head. Four patients with humeral head osteomyelitis were enrolled in this study. To make the cement spacer, we used the Mimics program, and designed the molding box by a reverse engineering technique. We evaluated the range of motion and pain using a Constant score. The mean abduction was $50^{\circ}$($40^{\circ}-60^{\circ}$), forward flexion was $50^{\circ}$ ($30^{\circ}-70^{\circ}$), and average Constant score was 47.75 (44-52). Three-dimensional printed molding technique is one of the effective methods for humeral head osteomyelitis allowing for daily activities prior to the second surgery.

Background: Asymmetry of the infraorbital rim can be caused by trauma, congenital or acquired disease, or insufficient reduction during a previous operation. Such asymmetry needs to be corrected because the shape of the infraorbital rim or midfacial skeleton defines the overall midfacial contour. Methods: The study included 5 cases of retruded infraorbital rim. All of the patient underwent restoration of the deficient volume using polyethylene implants between June 2005 and June 2011. The infraorbital rim was accessed through a subciliary approach, and the implants were placed in subperiosteal space. Surgical outcomes were evaluated using preoperative and postoperative computed tomography studies. Results: Implant based augmentation was associated with a mean projection of 4.6 mm enhancement. No postoperative complications were noted during the 30-month follow-up period. Conclusion: Because of the safeness, short recovery time, effectiveness, reliability, and potential application to a wide range of facial disproportion problems, this surgical technique can be applied to midfacial retrusion from a variety of etiologies, such as fracture involving infraorbital rim, congenital midfacial hypoplasia, lid malposition after blepharoplasty, and skeletal changes due to aging.

It is challenging to achieve sufficient hearing gain in patients with mixed hearing loss. In chronic middle ear diseases, conventional passive reconstructive surgeries often result in suboptimal hearing gain and additional hearing aids may have limitations due to insufficient sound amplification, occlusion effect, acoustic feedback, and skin irritation. Middle ear implantation (MEI) using Vibrant Soundbridge (VSB) is another option for auditory rehabilitation in mixed hearing loss as well as sensorineural hearing loss. The floating mass transducer of VSB can be placed on various middle ear structures either directly or using different types of couplers in order to deliver vibratory mechanical energy to the cochlea. We report a patient who presented with bilateral mixed hearing loss due to chronic otitis media and had limitations using conventional hearing aids in the worse hearing ear. The patient was successfully treated with MEI using the Bell coupler together with middle ear surgery in a single step.

Purpose: The purpose of this study is to evaluate the current status of discharge education and nursing needs of children after musculoskeletal surgery. Methods: The literature from research databases was reviewed and analyzed (using PubMed, RISS review, KISS, and Dbpia). Results: Children who have undergone musculoskeletal surgery face physical challenges due to the effects of splints and immobilization, and experience pain for a long time. Therefore, home care after discharge is of paramount importance in these cases. The discharge education needs of each patient vary with regard to the topic and period. Discharge education should be systematic and consistent, with an emphasis on understanding the needs of the patients and parents. Conclusion: While there are studies on the nursing needs of adult musculoskeletal surgery patients at discharge, studies on discharge nursing needs in children who have undergone musculoskeletal surgery are still insufficient. It is necessary to specifically identify the educational needs of parents of children undergoing musculoskeletal surgery. Interventions that improve the voluntary participation of patients and parents in active self-care need to be developed.

Untreated severe tricuspid regurgitation (TR) is associated with poor outcomes. Functional TR occurs secondary to dilatation of the annulus and tethering of the leaflets. Ring annuloplasty alone can correct most cases, but is insufficient in cases of severe annular dilatation due to severe leaflet tethering. In such cases, a tricuspid edge-to-edge technique may be an option. However, stitching of the leaflet tips alone is likely to result in tearing of the leaflets. Approximation of the durable chordae tendineae is considered helpful for this problem. Herein, we present the case of a 39-year-old man who had undergone open-heart surgery for acute type A aortic dissection 13 months earlier. A right mini-thoracotomy approach with a beating-heart strategy was used, which did not require unnecessary pericardial adhesiolysis and dissection. This technique had the advantage of reducing the operation time and the risk of bleeding. To summarize, we present a case of tricuspid valve repair in a high-risk patient with severe leaflet tethering that was successfully managed using these methods.

Objective : The aims in the management of thoracolumbar spinal fractures are not only to restore vertebral column stability, but also to obtain acceptable alignment of the thoracolumbar junction (T-L junction) to prevent complications. However, insufficient surgical correction of the thoracolumbar spine would be likely to cause late progression of abnormal kyphosis. Therefore, we identified the surgical factors that affected unfavorable radiologic outcomes of the thoracolumbar spine after surgery. Methods : This study was conducted in a single institution from January 2007 to December 2013. A total of 98 patients with unstable thoracolumbar spine fracture were included. In these patients, fixation was done through transpedicular screws with rods by three surgical patterns. We reviewed digital radiographs and analyzed the images preoperatively and postoperatively during follow-up visits to compare the change of the thoracolumbar Cobb angle with radiologic parameters and clinical outcomes. The unfavorable radiologic group was defined as the patients who were measured as having greater than 20 degrees of thoracolumbar Cobb angle on the last follow-up, or who underwent kyphotic progression of thoracolumbar Cobb angle greater than 10 degrees from the immediate postoperative state to final follow-up, or who had overt instrument failure with/without additional surgery. We assessed the risk factors that affected the unfavorable radiologic outcomes. Results : We had 43 patients with unfavorable radiologic outcomes, including 35 abnormal thoracolumbar alignments and 14 instrumental failures with/without additional surgery. The multivariate logistic regression test showed that immediate postoperative T-L junction Cobb angle less than 10.5 degrees was a statistically significant risk factor, as well as the presence of osteoporosis (p=0.017 and 0.049, respectively). Conclusion : Insufficient correction of thoracolumbar kyphosis was considered to be a major factor of an unfavorable radiological outcome. The spinal surgeon should consider that having a T-L junction Cobb angle larger than 10.5 degrees immediately after surgery could result in an unfavorable radiological outcome, which is related to a poor clinical outcome.

Sinus lifting was introduced for prosthetic reconstruction in 1960 decades by Boyne and is specifically used for implant surgery in maxillary posterior region with insufficient bony height and has been indicated for reconstruction of oro- antral and palato-alveolar cleft. We report that subtotal maxillectomy using sinus lifting and skin graft in mild maxillary cancer cases results in good prevention of oro-antral and oro-nasal fistula by preserving intact maxillary sinus mucosa and improves better functional outcome after maxillectomy.

Background: Although the erector spinae plane block has been used in various truncal surgical procedures, its clinical benefits in patients undergoing spinal surgery remain controversial. The aim of this meta-analysis was to evaluate the clinical benefits of erector spinae plane block in patients undergoing spinal surgery. Methods: We searched the Cochrane Library, PubMed, EMBASE, and China National Knowledge Infrastructure for randomized controlled trials comparing the erector spinae plane block with a nonblocked control for spinal surgery. Results: Twelve studies encompassing 696 subjects were included in our systematic review and meta-analysis. We found that the erector spinae plane block decreased postoperative pain scores and opioid consumption in the postoperative and intraoperative periods. Moreover, it prolonged the time to the first rescue analgesic, reduced the number of patients who required rescue analgesia, and lowered the incidence of postoperative nausea and vomiting. However, it did not exhibit efficacy in decreasing the incidence of urinary retention and itching or shortening the length of hospital stays, or the time to first ambulation. Conclusions: Erector spinae plane block improves analgesic efficacy among patients undergoing spinal surgery compared with nonblocked controls; however, there is insufficient evidence regarding the benefits of erector spinae plane block for rapid recovery.

A ruptured Achilles tendon at the calcaneus attachment, which does not include a bone that can be fixed, is called 'sleeve avulsion'. A small amount of tendon in the calcaneal region can be sutured to the proximal portion of the ruptured Achilles tendon or insufficient bone to be fixed. Hence, tendon-bone healing is expected, but the results are not good compared to other parts of the tear. The incidence of Achilles tendon rupture is 7 to 40 per 100,000 patients, and 25% of patients undergo direct suture or reconstruction surgery, and 7.6% of patients with sleeve avulsion injuries undergo surgery. Surgical treatment may be a better choice for Achilles tendon sleeve avulsion because no successful case of conservative treatment has been reported. Distal wounds above the ruptured tendon adjacent to the bony eminence can have wound healing problems because of the thin, soft tissue and hypovascularity. An appropriate surgical method must be selected for each patient.

Recently, in Korea, the septal extension graft from the septum or rib has become a common method of correcting a small or short nose. The success rate of this method has led to the blind faith that it provides superior tip projection and definition, and to the failure to notice its weaknesses. Even if there is a sufficient amount of cartilage, improper separation or fixation might waste the cartilage, resulting in an inefficient operation. Appropriate resection and effective fixation are essential factors for economical rhinoplasty. The septal extension graft is a remarkable procedure since it can control the nasal tip bidirectionally and three dimensionally. Nevertheless, it has a serious drawback since resection is responsible for septal weakness. Safe resection and firm reconstruction of the framework should be carried out. Operating on the basis of the principle of "safe harvest" and rebuilding the structures is important. Further, it is important to learn several techniques to manage septal weakness, insufficient cartilage quantity, and failure of the rigid frame during the surgery.
