چکیده

Backhrounds: To determine the minimum incision size needed utilizing an opencubital tunnel technique to obtain equivalent and adequate visualization comparableto endoscopic technique.Methods:On ten fresh-frozen cadavers with a -2cm incision, visualization was assessedby percutaneous needle localization using the endoscopic system. The most proximaland distal extent of field of view was marked. Next, an open cubital tunnel release wasperformed on each cadaver specimen. The incision size was increased incrementallyand the most proximal and distal extents of visualization were recorded for eachincision size. The mean visualization distance and standard deviation for each incisionallength was calculated.Results: The mean proximal field of view with the endoscopic technique was 8.1 cm.The mean distal field of view was 8.3 cm. Using the open technique a -2cm incisionallowed 5.9 cm visualization proximally and 5.2 cm distally, which was significantlyless than the endoscopic view. A -4cm open incision provided similar visualization asthe endoscopic technique. A -6cm open incision was required to obtain statisticallysignificant improvements in visualization compared to endoscopic.Conclusions: A -4cm open incision was required to obtain equivalent visualizationto the endoscopic technique for cubital tunnel release. Incision of 6cm is required tovisualize 10cm proximal and distal to the medial epicondyle.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
