Purpose: To analyze the result of a repeat discectomy for ipsilateral recurrent lumbar disc herniation and to investigate the potential factors that influenced the outcomes for this surgery. Materials and Methods: Fifty-nine patients, who underwent reoperation after lumbar discectomy with a minimum follow-up period of 2 years, were reviewed. The surgical outcome was assessed using the visual analogue scale (VAS) and Macnab classification, and the recovery rate was calculated in accordance with VAS. A statistical analysis was carried out by SPSS to evaluate the possible factors that may have influenced the outcomes of the reoperation. Results: The rate of reoperation after lumbar disc surgery due to the recurrent disc herniation was 6.0% (59/983 cases). The average recovery rate of VAS from the 1st operation was approximately 77%, and from the 2nd operation was 71%. According to the Macnab criteria, the results were "excellent" or "good" in 96% of cases. Statistical analysis revealed that there was no difference of the average recovery rate (p<0.05). There is no additional instability after repeat discectomy. Factors, such as smoking, precipitating traumatic events, and diabetes mellitus did not have much influence on the average recovery rate after repeat discectomy for ipsilateral recurrent lumbar disc herniation. Conclusion: The outcomes of repeat discectomy were satisfactory. Moreover, factors, smoking, trauma history and diabetic mellitus, only had a minor impact on the outcomes of a repeat discectomy.

Lumbar decompressive surgery is a standard surgery for lumbar spinal stenosis. Many surgical techniques have been introduced, ranging from open surgery to percutaneous procedures. Minimally invasive techniques are preferred because of the less postoperative pain and shorter hospital stay. Uniportal percutaneous endoscopic decompression has technical difficulties due to the narrow field. Biportal percutaneous endoscopic decompression is a satisfactory technique that can compensate for the shortcomings and provide sufficient decompression.

Total knee arthroplasty is performed widely in degenerative arthritis of the knee joint, and the frequency of use is increasing. Efforts should be made to achieve functional recovery, such as returning to daily life, and the recovery of strength and range of motion after surgery. The procedure should be approached from a range of perspectives, such as patient factors, surgical technique and rehabilitation. The patient's age, degree of obesity, sex, and strength of the quadriceps muscle can affect the functional recovery after surgery. In addition, the patient's mental state, such as expectation value and satisfaction, can also have an effect. For functional recovery, patient education, pain control, and strengthening of the quadriceps muscle can be performed prior to surgery. Postoperative physiotherapy, such as icing and compression, transcutaneous electrical nerve stimulation therapy, neuromuscular electrical stimulation therapy, low frequency low intensity magnetic field therapy, strengthening of quadriceps muscle, and range of motion exercise can also be applied. In recent years, hydrotherapy, which restores the strength and balance of the leg, is being performed increasingly. These treatments are not only performed shortly after surgery, but are also performed continuously. In addition, the surgeon should apply it appropriately considering the patient's condition, compliance, and social and psychological conditions.

Purpose: To report the clinical results from surgical treatment for clavicle shaft fracture by percutaneous intramedullary fixation with Steinmann pins. Materials and Methods: Between January 2004 and June 2014, the medical records of 135 patients who underwent percutaneous intramedullary fixation with Steinmann pins were reviewed. The mean follow-up periods were 15 months. The functional results were evaluated with The Disabilities of the Arm, Shoulder and Hand (DASH) score and Constant score. The clinical results were evaluated with the shortened length of the clavicle, length of surgical wound, operation time and Kang's criteria. Results: The mean bone union period was 11.6 weeks (8-16 weeks). The mean DASH score was 11.8. The mean Constant score was 91.2. The mean shortened length of the clavicle was less than 20 mm. The mean length of surgical wound was 1.2 cm (0.7-1.5 cm). The mean operation time was 18 minutes (10-35 minutes). Using Kang's criteria, 131 out of 135 patients (97.0%) showed good results. Complications included were 3 pin migrations and 2 non-unions. Conclusion: Percutaneous intramedullary fixation with Steinmann pins showed good results for treating clavicle shaft fracture.

This study was conducted to analyze the results of inhalation anesthesia performed at the equine hospital of Korea Racing Authority (KRA) and to find out the influencing factors on mortality during and/or after inhalation anesthesia. Among 585 cases of anesthesia, orthopedic surgery (410) was performed the most frequently, followed by colic surgery (85) and upper airway surgery (45). Twenty out of 585 horses were either euthanized or died during and/or after anesthesia. Among those twenty horses, fourteen horses received colic surgery, three received orthopedic surgery, and three others received upper airway surgery. The major causes of mortality were rupture of intestine in colic surgery and airway obstruction during recovery in upper airway surgery. Myopathy, refracture, laminitis were the causes of mortality in orthopedic surgery. Consequently, the horses that received colic and upper airway surgeries showed significantly high mortality rate rather than horses that received orthopedic surgery (p < 0.01). According to the results, horses that received colic surgery showed the highest mortality rate from euthanasia due to poor and grave prognosis. To reduce the perioperative mortality of horses, it is recommended to perform perioperative intensive care for colic surgery and careful monitoring for upper airway surgery during recovery.

Purpose: To compare and analyze the rate of prevention of two venous thromboembolism prophylaxis guidelines in patients with artificial joint arthroplasty and hip joint fracture. Proper prophylaxis for preventing thromboembolism in orthopedic surgery is significant because of this fetal complication. Materials and Methods: This study compared and retrospective analyzed the rate of prevention using the medical records and radiographs of patients who underwent orthopedic surgery from March 2009 to February 2011 according to the American College of Chest Physicians (ACCP) guidelines and from March 2012 to February 2014 according to the American Academy of Orthopedic Surgeons (AAOS) guidelines. Results: The guidelines for venous thromboembolism prophylaxis have been applied to patients with artificial joint replacement and hip joint fracture, the compliance rate of the ACCP guidelines was 56.0% before surgery, 67.0% after surgery with chemical prophylaxis, and 80.5% with mechanical prophylaxis. In addition, the compliance rate of the AAOS guidelines was 74.1% with chemical prophylaxis, and 88.3% with mechanical prophylaxis, which was higher than the ACCP guidelines. The compliance rates of mechanical and chemical prophylaxis before and after surgery of the ACCP guidelines, and the compliance rate of mechanical and chemical prophylaxis of the AAOS guidelines were compared and analyzed. The results revealed statistical significance (p<0.05) before and after total knee replacement arthroplasty and hip joint fracture internal fixation and total high risk orthopedic surgery. Conclusion: Raising the compliance rate of prophylaxis of venous thromboembolism in high risk orthopedic surgery is necessary and people should follow the guidelines for a unified direction depending on which situation they are in.

Purpose: In the treatment of Dupuytren's contracture, the aim of optical treatment is to lower the recurrence rate and reduce complications. This paper reports the results of subtotal fasciectomy in Dupuytren's contracture, extending the excision of palmar fascial structures from the diseased to normal appearing adjacent fascial structure. Materials and Methods: From 2007 to 2017, 45 patients with Dupuytren's contracture treated by subtotal fasciectomy were reviewed retrospectively. The mean follow-up period was 45.9 months. Ninety-two digits were involved (index: 2, middle: 10, ring: 44, little: 36). The predisposing factors and affected joint were reviewed and the preoperative and postoperative contracture was measured. For clinical results, quick disabilities of the arm, shoulder, and hand (quick DASH) were used. Complications, including wound or skin problems, nerve injuries, hematoma, and complex regional pain syndrome, were assessed. Results: Preoperative flexion contracture was 43.2° in the proximal interphalangeal joint and 32.9° in the metacarpophalangeal joint. In nine cases, patients had residual contracture of 9.7° (range, 5°-20°) on average and if the total number of cases were included, the mean residual contracture was 2.3° on average. The quick DASH score at the 12 months follow-up was 12.4. The overall complication rate was 26.6%. Conclusion: Subtotal fasciectomy can be a good surgical treatment option for Dupuytren's contracture with a low recurrence and low complication rate compared to other open procedures.
