Patients in group C exhibited the lowest volume of drainage on POD 1 (178.33 ± 66.76 mL), which showed significant difference compared with group A (368.33 ± 191.15 mL, = 0.01). There was no significant difference of preoperative and postoperative VAS and JOA score among three groups, as well as drainage on POD 2, total volume and hospital duration. Both embolization and vertebroplasty are efficient and safe measures to reduce blood loss in the surgical treatment of aggressive vertebral hemangiomas, combination of all three methods is also competent.Both embolization and vertebroplasty are efficient and safe measures to reduce blood loss in the surgical treatment of aggressive vertebral hemangiomas, combination of all three methods is also competent. Taiwan's response to the coronavirus disease 2019 (COVID-19) differed in that it successfully prevented the spread without having to shutdown or overburden medical services. Patients' fear regarding the pandemic would be the only reason to reduce surgeries, so Taiwan could be the most suitable place for research on the influence of psychological factors. This study aimed to assess the impact of patients' fear on orthopedic surgeries in Taiwan amid the peak period of the COVID-19 pandemic. The investigation period included the COVID-19 pandemic (March 2020 to April 2020) and the corresponding period in the previous year. The following data on patients with orthopedic diseases were collected outpatient visits, hospital admission, and surgical modalities. The COVID-19 pandemic led to a 22%-29% and 20%-26% reduction in outpatients, 22%-27% and 25%-37% reduction in admissions, and 26%-35% and 18%-34% reduction in surgeries, respectively, at both hospitals. Milciclib in vivo The weekly mean number of patients was significantly smaller during the COVID-19 pandemic for all types of surgery and elective surgeries at the university hospital, and for all types of surgery, elective surgeries, and total knee arthroplasties at the community hospital. Further, patients visiting the community hospital during the pandemic were significantly younger, for all types of surgery, elective surgeries, and total knee arthroplasties. The reduction in orthopedic surgeries in Taiwan's hospitals during COVID-19 could be attributed to patients' fear. Even without restriction, the pandemic inevitably led to a reduction of about 20%-30% of the operation volume.The reduction in orthopedic surgeries in Taiwan's hospitals during COVID-19 could be attributed to patients' fear.

Proper placement of infra-acetabular screws is technically demanding; there is a limited safe zone for screw fixation because of the complexity of the bone anatomy around the hip joint and the vulnerability of the major neurovascular bundles in the pelvic cavity. We aimed to present the obturator hook technique as a surgical technique for infra-acetabular screw placement in acetabular and pelvic fractures and report its radiological outcomes. Patients treated with infra-acetabular screw placement using the obturator hook technique between January 2015 and August 2020 were enrolled in this study. We collected data on demographics, surgical approach, reduction status, complications, and outcomes. The radiological outcomes of infra-acetabular screw placement based on computed tomography findings were evaluated as follows success, articular penetration, or out of the bone. Thirty-five patients underwent infra-acetabular screw placement (26 men, 9 women; mean age, 55 years; range, 27-90 years). One patient underwent bilateral infra-acetabular screw placement; therefore, 36 infra-acetabular screws were inserted in all patients. An ideal placement was achieved with 27 infra-acetabular screws (27/36, 75%). Seven infra-acetabular screws (7/36, 19%) showed articular penetration, and two infra-acetabular screws (2/36, 6%) were placed outside the bone. One patient with articular penetration and mechanical symptoms of the hip joint required screw replacement. No other complications, including obturator nerve and vascular injuries, were observed. The obturator hook technique could be a favorable and individualized method for infra-acetabular screw placement in patients with acetabular and pelvic fractures.

Supraretinacular endoscopic carpal tunnel release (SRECTR) is a technique in which an endoscope is inserted superficial to the flexor retinaculum through a subcutaneous tunnel. The benefits of this method include a clear view for the surgeon and absence of median nerve compression. Surgeons can operate with a familiar view of the flexor retinaculum and median nerve downward, similar to open surgery. This study aimed to investigate the learning curve for SRECTR, an alternate method for carpal tunnel release, and evaluate its complications and the functional outcomes using a disposable commercial kit. We examined the open conversion rates and complications associated with SRECTR in 200 consecutive patients performed by two surgeons. We compared the operative time operated by a single surgeon. We evaluated outcomes in 191 patients according to Kelly's grading system. Patients' mean follow-up period was 12.7 months. Nine patients required conversion to open surgery. There were no injuries to the nerves and tendons and no hematoma or incomplete dissection of the flexor retinaculum. The operative times varied between 11 and 34 minutes. We obtained the following results based on Kelly's grading of outcomes excellent in 116, good in 59, fair in 13, and poor in 3 patients. We found no patients with neurapraxia, major nerve injury, flexor tendon injury, superficial palmar arch injury, and hematoma. Although there was a learning curve associated with SRECTR, we performed 200 consecutive cases without neurovascular complications. This method may be a safe alternative to minimally invasive carpal tunnel surgery.We found no patients with neurapraxia, major nerve injury, flexor tendon injury, superficial palmar arch injury, and hematoma.
