Study Design: A retrospective clinical and radiographic review. Objectives: The purpose of this study was to suggest recycling bone autotransplantation with extracorporeal heat-treatment as one of favorable reconstruction method for malignant bone tumors of pelvis through 3 cases. Summary of Literature Review: There are many biologic and nonbiologic reconstruction method in pelvic reconstruction. Cases: Case 1- A 20-year-old women had chief complaint of right hip and thigh pain started 3 months ago and done curettage and bone cementing at right ilium at other hospital. She had impression of malignant bone tumor and undergone postoperative radiation therapy for 6 cycles. After that she was referred to our hospital and undergone wide excision of right ilium and recycling bone autotransplantation with extracorporeal heat-treatment at 132 degree celsius for 2 minutes internal fixation with pelvic reconstruction plate and total hip replacement arthroplasty (ABG$^{(R)}$). There was no evidence of distant metastasis and revealed well-differentiated osteosarcoma on postoperative pathology. Neither adjuvant nor neoadjuvant chemotherapy were done. Case 2- A 56-year-old women who suffered right thigh pain for 3 months was detected radiologic abnormality at right pelvis. After incisional biopsy, osteosarcoma was diagnosed. We had undergone wide excision of right ilium and recycling bone autotransplantation with extracorporeal low heat-treatment at 65 degree celsius for 30minutes internal fixation with pelvic reconstruction plate and total hip replacement arthroplasty (ABG$^{(R)}$). There was no evidence of distant metastasis and revealed high-grade osteosacoma which was fibroblastic type on postoperative pathology. Adjuvant chemotherapy (HDMTX, ADR, CDDP) was done immediate after wound healing was completed. Case 3- A 46-year-old women was incidently found mass at left ilium which was suspected chondrosarcoma. We had undergone wide excision of left ilium and recycling bone autotransplantation with extracorporeal low heat-treatment at 65 degree celsius for 30minutes internal fixation with pelvic reconstruction plate and total hip replacement arthroplasty (Protek$^{(R)}$). There was no evidence of distant metastasis and revealed chondrosarcoma which was graded II/III on postoperative pathology. Results: Oncologic and functional outcome at final follow-up were for case 1, final follow-up time was 7 years, is no evidence of disease and functional score is 53% according to Ennecking et al. During follow-up, evidence of radiologic union was at about 1 and 6 months after operation. The case had breakage of pelvic reconstruction plate and some resorption of autotransplated bone, but no symptom present. For case 2, final follow-up was 3 years and 6 months, is no evidence of disease and functional score is 60%. For case 3, final follow-up was 7 months, no evidence of disease and functional score is 63% which is improving state. Discussion: 3 cases which were undergone recycling bone autotransplantation with extracorporeal heat-treatment and total hip replacement arthroplasty had relatively successful oncologic and functional outcome. Taking account that difficulty in using allograft in Korea this method is thoght to be one of the useful way to reconstruct pelvis after resection of primary malignant bone tumor of the pelvis.

Purpose: To compare coagulation test results of the arthroscopic surgery patients who received thromboprophylaxis with typical two kinds of anticoagulation drugs, we performed coagulation tests before and after surgery with two groups and then compared the results. Materials and Methods: Forty-seven patients who underwent arthroscopic surgery were randomly divided into two groups to rivaroxaban and enoxaparin group, and we performed coagulation tests before and 5 days after arthroscopic surgery to two drugs groups in order to investigate about the difference in clotting capacity. Results: Preoperative coagulation tests did not differ significantly between the two groups. However, coagulation tests after 5 days of the surgery, the level of prothrombin time-international normalized ratio (PT-INR), activated partial thromboplastin time (aPTT) increased, particularly in patients with rivaroxaban compared with enoxaparin (P<0.05). Conclusion: Anticoagulation for arthroscopic surgery with a drug is effective and has safe range in terms of bleeding tendency, but in the rivaroxaban group, there was one patient who showed high bleeding tendency with abnormal range. Therefore it should be careful of using rivaroxaban for thromboprophylaxis.

Purpose: This study was designed to determine the effects of pre-warming on core body temperature (CBT) and hemodynamics from the induction of spinal anesthesia until 30 min postoperatively in surgical patients who undergo total hip replacement under spinal anesthesia. Our goal was to assess postoperative shivering and inflammatory response. Methods: Sixty-two surgical patients were recruited by informed notice. Data for this study were collected at a 1,300-bed university hospital in Incheon, South Korea from January 15 through November 15, 2013. Data on CBT, systemic blood pressure (SBP), and heart rate were measured from arrival in the pre-anesthesia room to 3 hours after the induction of spinal anesthesia. Shivering was measured for 30 minutes post-operatively. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were measured pre-operatively, and 1 and 2 days postoperatively. The 62 patients were randomly allocated to an experimental group (EG), which underwent pre-warming for 30 minutes, or a control group (CG), which did not undergo pre-warming. Results: Analysis of CBT from induction of spinal anesthesia to 3 hours after induction revealed significant interaction between group and time (F=3.85, p=.008). In addition, the incidence of shivering in the EG was lower than that in the CG ($x^2=6.15$, p=.013). However, analyses of SBP, heart rate, CRP, and ESR did not reveal significant interaction between time and group. Conclusion: Pre-warming for 30 minutes is effective in increasing CBT 2 and 3 hours after induction of spinal anesthesia. In addition, pre-warming is effective in decreasing post-operative shivering.

To improve surgical result of total hip arthroplasty (THA), there has been some approaches using a robotic milling system, which can make a precise cavity in the femur. Usually, to carve a femur, the surgical robot is controlled by a pre-programmed tool-path regardless of a surgeon's experience and Judgment. This paper presents a control method of a surgical robot for THA, which can be used as an advanced surgical tool. With a master/slave combined surgical robot, surgeon can directly control the motion and velocity of a surgical robot. The master/slave-combined robot is controlled to display a specific admittance for a surgeon's force to the surgical robot velocity. To prevent the over-carving of a femur, virtual hard wall is displayed on the surgical boundary. To evaluate the proposed control method of the master/slave-combined surgical robot, 2-DOF master/slave-combined manipulator is used in experiment.

The use of 3-dimensional (3D) printing is becoming more common, and its use is increasing in the orthopedic surgery. Currently, there are four major methods of using 3D printing technology in orthopedic surgery. First, surgical planning simulation using 3D printing model; second, patient-specific surgical instruments; third, production of customized prosthesis using 3D printing technique; fourth, patient-specific prosthesis produced by 3D printing. The areas of orthopedic surgery where 3D printing technology can be used are shoulder joint, spine, hip and pelvis, knee joints, ankle joint, and tumors. Since the diseases and characteristics handled by each area are different, the method of using 3D printing technology is also slightly different in each area. However, using 3D printing technology in all areas can increase the efficiency of surgery, shorten the surgery time, and reduce radiation exposure intraoperatively. 3D printing technology can be of great help in treating patients with particularly complex and difficult orthopedic diseases or fractures. Therefore, the orthopedic surgeon should make the most of the benefits of the 3D printing technology so that patient can be treated effectively.

The aim of this review was to evaluate minimally invasive lateral lumbar interbody fusion on the latest update. Lumbar interbody fusion was introduced recently. This study performed, a literature review of the indications, clinical outcomes, fusion rate, and complications regarding recently highlighted minimally invasive lateral lumbar interbody fusion. The indications of lateral lumbar interbody fusion are similar to the conventional anterior and posterior interbody fusion in degenerative lumbar diseases. In particular, lateral lumbar interbody fusion is an effective minimally invasive surgery in spinal stenosis, degenerative spondylolisthesis, degenerative adult deformity, degenerative disc disease and adjacent segment disease. In addition, the clinical outcomes and fusion rates of lateral lumbar interbody fusion are similar compared to conventional lumbar fusion. On the other hand, non-specific complications including hip flexor weakness, nerve injury, vascular injury, visceral injury, cage subsidence and pseudohernia have been reported. Lateral lumbar interbody fusion is a very useful minimally invasive surgery because it has advantages over conventional anterior and posterior interbody fusion without many of the disadvantages. Nevertheless, nonspecific complications during lateral lumbar interbody fusion procedure remain a challenge to be improved.

The purpose of this study was to investigate the effect of different arthroplasty designs on knee kinematic and lower limb muscular activation for up-stair and down-stair movement. 3-D video analysis of whole body and joint kinematics and EMG analysis of quadriceps and hamstrings were conducted. One-way ANOVAs were used for statistical analyses (p=0.05). The single-radius group exhibited more arthroplasty limb quadriceps EMG and hamstring coactivation EMG than the multi-radius group. Single-radius demonstrated more abduction angular displacement and reached peak abduction earlier than the multi-radius arthroplasty limb. The single- radius the percent body fat showed similar values in the Elderly, Single and Multi-radius group among the periods, however Control group was Lowered among the periods. Single-radius group limb also increased the quadriceps muscle activation level to produce more knee extension moment to compensate for the short quadriceps moment arm. Resting metabolic rate was significantly increased in control group in the period of LI. Energy expenditure was extremely increased in all groups except control group among the periods. We can say this is the exercise effects.

A 9-month-old female Korean short hair cat weighing 2.2 kg presented for evaluation of a two-week history of obstipation. The owner reported that the cat sustained pelvic fractures 4 months previous to the onset of fecal tenesmus. On physical examination, fecal tenesmus was observed and restriction of the movement of the right coxofemoral joint was evident. Rectal palpation revealed narrowing of the pelvic canal with a hard bony protuberance at the bilateral acetabulum and pubic bones. Radiographs revealed a distended colon with feces and narrowing of the pelvic canal with abnormal structure of the pelvic bone. Conservative management consisting of stool softeners and a warm water enema was instituted; however, there was no improvement in obstipation. Partial iliac, ischial, pubic, and acetabular ostectomies were performed. Postoperative radiographs and rectal palpation revealed the enlarged pelvic canal. Stool softeners (5 ml orally twice daily) was administered following surgery for 14 days and then tapered down to 2.5 ml for 14 days. A warm water enema was performed twice postoperatively. At examination 14 days postoperatively, no problems with defecation and gait were reported. There was no evidence of obstipation and lameness of the left pelvic limb 5 months postoperatively.

Background: As the patients who undergo heart transplantation have achieved better survival in recent years, growing number of recipients are at a risk for experiencing surgical complications in addition to rejection and infection. In this paper, we report on our experience with the surgical complications that occurred in heart transplant recipients. Material and Method: From April 1994 to September 2003, 37 heart transplantations were performed at our center by a single surgeon. The indications for transplantation were dilated cardiomyopathy, ischemic cardiomyopathy, valvular cardiomyopathy and familial hypertrophic cardiomyopathy. Result: Twenty postoperative complications required surgeries in 15 patients (41%). The types of operations required were; redo-sternotomy for bleeding (5), pericardiostomy for effusion (4), implantation of a permanent pacemaker (1), right lower lobe lobectomy for aspergilloma (1), removal of urinary stone (1), cholecystectomy for gall bladder stone (1), drainage of a perianal abscess (1), paranasal sinus drainage (1), total hip replacement (1), partial gingivectomy due to gingival hypertrophy (1), urethrostomy (1), herniated intervertebral disc operation (1) and total hysterectomy for myoma uteri (1). The locations of the complications were mediastinal in 10 (27%) cases and extramediastihalin 10 (27%) cases. Conclusion: The relatively high incidence of extrathoracic complications associated with heart transplantation emphasizes the importance of a multidisciplinary approach to the improve long-term survival when managing those complex patients.
