Objective: To describe the results of the endoscopic carpal tunnel release using the MicroAire Carpal Tunnel Release System. Methods: This descriptive study was conducted from June 2007 to May 2009 on 63 patients (68 hands) who underwent endoscopic carpal tunnel release for severe carpal tunnel syndrome in the Royal Jordanian Rehabilitation Center at King Hussein Medical Center. The procedure w...

BACKGROUND Remnant preservation may confer important advantages in the anterior cruciate ligament (ACL)-reconstructed knee. However, the presence of a large remnant may obscure visualization and impair the ability to correctly place tunnels during surgery. PURPOSE To determine whether tunnel placement during anatomic ACL reconstruction using the single anteromedial bundle biological augmentat...

PURPOSE The object of this study was to evaluate entrance angle effects on femoral tunnel length and cartilage damage during anteromedial portal drilling using three-dimensional computer simulation. MATERIALS AND METHODS Data was obtained from an anatomic study performed using 16 cadaveric knees. The anterior cruciate ligament femoral insertion was dissected and the knees were scanned by comp...

BACKGROUND There is controversy regarding the necessity of reconstructing both the posterolateral and anteromedial bundles of the anterior cruciate ligament. HYPOTHESIS A laterally oriented transtibial drilled femoral tunnel replaces portions of the femoral footprints of the anteromedial and posterolateral bundles of the anterior cruciate ligament. STUDY DESIGN Descriptive laboratory study....

With the large-scale construction and rapid development of underground engineering, a large number of underground engineering construction, such as tunnel and subway emerged. The geological structure of the tunnel is complex and the roc is fragmented. The electromagnetic tomography is a new geophysical technique in the tunnel. This method has advantages such as high resolution, high reliability...

The rapid growth in mobile traffic leads to the current evolution trend of mobile networks towards a flat architecture. However, the centralized mobility management protocols (e.g. MIPv6, PMIPv6) are not optimized for the flat architecture due to their limitations e.g. complex tunnel management, scalability issue, etc. Hence, a novel mobility management has been proposed for the flat architectu...

Urban road tunnels provide an increasingly cost-effective engineering solution, especially in compact cities like Singapore. For some urban road tunnels, tunnel characteristics such as tunnel configurations, geometries, provisions of tunnel electrical and mechanical systems, traffic volumes, etc. may vary from one section to another. These urban road tunnels that have characterized nonuniform p...

Bone tunnel enlargement following anterior cruciate ligament (ACL) reconstruction can complicate revision surgery. This study compared postoperative tibial tunnel widening in patients who underwent arthroscopically assisted, single-incision, four-strand hamstring ACL reconstruction using a poly-L-lactic acid/hydroxyapatite blend (PLLA+HA) bioabsorbable interference screw for tibial fixation, wi...

The median artery is the main source of blood for the forearm in intrauterine life. During the process of development the median artery gets obliterated and supplies the median nerve. Variation of persistent median artery and its accompanying with the median nerve in the carpal tunnel is one of the important anatomic variations of the upper limb. Thrombosis of the artery inside the carpal tunne...

BACKGROUND Previous studies have shown that the carpal tunnel syndrome seems to occur more frequently in patients with diabetes mellitus and might be associated with the duration of diabetes mellitus, microvascular complications and degree of glycaemic control. Primary aim was to determine if type 2 diabetes can be identified as a risk factor for carpal tunnel syndrome after adjusting for possi...
