Nine patients with myxoedema and carpal tunnel syndrome have been studied clinically and electrophysiologically to determine the presence or absence of the tarsal tunnel syndrome. Four patients had electrophysiological evidence of the tarsal tunnel syndrome, three of whom were mildly symptomatic. This would suggest that the tarsal tunnel syndrome is frequently encountered in myxoedema in associ...

Aorta-right atrial tunnel was diagnosed in a non-symptomatic 31-year old female patient. The Q p /Q s ratio was 2.5. Computed tomography and intraoperative views showed a posterior vascular tunnel with left aortic sinus and right atrium openings (Figs 1 and 2). The tunnel had no myocardial branches. We successfully closed both the openings. Figure 1: (A) A reconstructed computed tomographic vie...

INTRODUCTION: Clinical studies of carpal tunnel syndrome (CTS), a pressure-induced neuropathy of the median nerve, are limited by the difficulty of evaluating the early stages of pathology. Thus, a validated animal model of CTS is an important need. A proper animal model would have comparable anatomy to the human carpal tunnel. In addition, because carpal tunnel syndrome is characterized by inc...

BACKGROUND An anatomic reconstruction of coracoclavicular (CC) ligaments typically requires drilling tunnels in the clavicle. An increase in fracture complications has been associated with graft tunnel position. A method of drilling clavicle tunnels that would better re-create anatomic function of the CC ligaments without increasing fracture risk would be an improvement. PURPOSE To evaluate t...

BACKGROUND Anatomic tunnel positioning is important in anterior cruciate ligament (ACL) reconstructive surgery. Recent studies have suggested the limitations of a traditional transtibial technique to place the ACL graft within the anatomic tunnel position of the ACL on the femur. The purpose of this study is to determine if the 2-incision tibial tunnel-independent technique can place femoral tu...

Wind tunnel experiments were carried out on four urban morphologies: two tall canopies with uniform-height and super-tall a large variation in element heights (where the maximum height is more than double average canopy height, $h_{max}$=2.5 $h_{avg}$). {The packing density fixed across surfaces to $h_{avg} = 80$ mm, $\lambda_{p} 0.44$, respectively.} A combination of laser doppler anemometry d...

PURPOSE To evaluate the interobserver and intraobserver reliability of radiographic assessment of tunnel placement in anterior cruciate ligament reconstruction. METHODS Seven sports fellowship-trained orthopaedic surgeons in the Multicenter Orthopaedic Outcomes Network (MOON) group participated in the study. We prospectively enrolled 54 consecutive patients after primary anterior cruciate lig...

This study investigates the aerodynamics of the falcon Falco peregrinus while diving. During a dive peregrines can reach velocities of more than 320 km h⁻¹. Unfortunately, in freely roaming falcons, these high velocities prohibit a precise determination of flight parameters such as velocity and acceleration as well as body shape and wing contour. Therefore, individual F. peregrinus were trained...

Wind-blown pool fire accidents in a ventilated tunnel usually pose and present serious risks to properties personal safety. In this paper, the flame characteristics flow field changes of fires under combined influence baffles crosswinds were investigated using wind experiments numerical simulations. The reveal that length increases first, then decreases with increasing crosswind speeds up 3 m/s...

According to construction scheme of some weak surrounding rock large span double and multi-arch tunnel works, finite element value simulation method is adopted to research weak surrounding rock deformation characteristic, anchor bolt mechanics characteristic, preliminary support and secondary lining structure mechanical characteristics, etc, and the research result shows that: repeatedly distur...
