The purpose of this study was to compare the T-anchor with the EndoButton Direct. This study was conducted on 30 cadaveric knees (15 matched pairs). There were two groups of 15 each in the T-anchor and EndoButton Direct groups. After the harvest of grafts, fixation site profile and graft length were measured by loading the grafts onto both devices. They were then tested on a universal testing machine to assess elongation after cyclic loading, load to failure, ultimate load, and mode of failure. The fixation site profile was lower in the T-anchor group than in the EndoButton Direct group (2.3±0.4mm vs. 4.7±1.0mm, P<0.001). The length of the graft-device complex of the T-anchor specimens was longer than that of the EndoButton Direct specimens (125.0±8.9mm vs. 115.0±8.7mm, P<0.001). The mean cyclic elongation was lower for the T-anchor group when comp...

Orthopaedicians have been associated with POP just like cardiologists with ECG and the plastic surgeons with Humby's knife. Its use is ubiquitous and we put it to such a myriad of uses that the list is endless.

Numerous clinical trials have documented the efficacy and safety of intravenous (IV) or intraarticular (IA) use of tranexamic acid. Combined administration of tranexamic acid also has been suggested; however, there is no consensus regarding the ideal route of tranexamic acid administration. (1) To compare the efficacy of tranexamic acid in terms of total blood loss and the allogeneic transfusion rate among three routes of administration: IV alone, IA alone, and combined IV and IA. (2) To compare these regimens in terms of venous thromboembolism (VTE) and the frequency of wound complications. In total, 376 patients undergoing TKA between March 2014 and March 2015 were randomized to four groups by the route of tranexamic acid administration: IV only, IA only, low-dose combined (IV + IA injection of 1 g), and high-dose combined (IV + IA injection of 2 g). The calculated total ...

The frequently occurring mechanisms of injury include axial compression, hyper-flexion, hyper-extension, and rotational type injuries. Good pre-hospital care and a thorough assessment in the emergency department of patients suspected to have a cervical spine injury (CSI) leads to improved clinical outcomes. The objective of the initial evaluation of a patient with a suspected CSI is to identify the presence of injuries through thorough clinical and radiologic assessments as missed injuries are potentially catastrophic. The treatment of cervical spine injuries can be conservative, pharmacological, or surgical, and aims to halt SCI progression, stabilize the spine, and to allow rehabilitation of the patient.

The purpose of this study was to compare the T-anchor with the EndoButton Direct. Methods: This study was conducted on 30 cadaveric knees (15 matched pairs). There were two groups of 15 each in the T-anchor and EndoButton Direct groups. After the harvest of grafts, fixation site profile and graft length were measured by loading the grafts onto both devices. They were then tested on a universal testing machine to assess elongation after cyclic loading, load to failure, ultimate load, and mode of failure. Results: The fixation site profile was lower in the T-anchor group than in the EndoButton Direct group (2.3 ± 0.4 mm vs. 4.7 ± 1.0 mm, P b 0.001). The length of the graft-device complex of the T-anchor specimens was longer than that of the EndoButton Direct specimens (125.0 ± 8.9 mm vs. 115.0 ± 8.7 mm, P b 0.001). The mean cyclic elongation was lower for the T-anchor group when compared with the EndoButton Direct group (2.4 ± 0.6 mm vs. 3.9 ± 2.6 mm, P = 0.015). There was no statistically significant difference in ultimate load and load to failure between the T-anchor and EndoButton Direct groups. For mode of failure, the T-anchor fared better (P = 0.013) with all failures attributed to specimens. Conclusions: In this cadaveric study, the new device, T-anchor, performed better than the EndoButton Direct with respect to the above-mentioned study parameters except for ultimate load and load to failure.
