A Method to Visualize and Quantify the Intraosseous Arteries of the Femoral Head by Vascular Corrosion Casting.

Objective: To describe a method to display the three-dimensional distribution of intraosseous arteries in the femoral head by vascular corrosion casting.

Methods: An experimental study was done to expose the intraosseous arteries of the femoral head by a microperfusion corrosion method between January 2021 and May 2021. Specimens were 23 swine femoral heads (12 female specimens and 11 male specimens, where age of swine ranged from 8 to 12 months, and the weight was approximately 150 kg).

A flap based on the plantar digital artery arch branch to improve appearance of reconstructed fingers: Anatomical and clinical application.

Aim: To investigate blood supply features of the flap based on the plantar digital artery arch and arch branch artery, and the treatment of outcomes of reconstructed fingers by the plantar digital artery arch branch island flap.

Methods: Eight fresh foot specimens were employed with red emulsion infusion and microdissection. The vascular organization was observed in the second toe, such as initiation site, the course, and the number of the plantar digital artery arch branch.

Role of the p38 mitogen-activated protein kinase signaling pathway in estrogen-mediated protection following flap ischemia-reperfusion injury.

Ischemia-reperfusion (I/R) injury often occurs during skin flap transplantation and results in tissue damage. Although estrogen treatment significantly alleviates this I/R injury-induced damage, the detailed molecular mechanism is not clear. In this study, a superficial epigastric artery flap I/R injury model was created in adult Wistar rats.

Comparison of treatment outcomes between nonsurgical and surgical treatment of distal radius fracture in elderly: a systematic review and meta-analysis.

Purpose: The best treatment of distal radius fractures (DRFs) in the elderly is uncertain. The purpose of this meta-analysis was to compare the outcomes of surgical and nonsurgical management of DRFs in persons 65 years of age or older.

Methods: Medline, Cochrane, EMBASE, and Google Scholar databases were searched until April 27, 2015 using the following search terms: distal radius fracture, conservative treatment, nonoperative treatment, nonsurgical treatment, surgical treatment, operative, elderly, and older.

Repair of a degloving injury of the thumb with a combined dorsal great toenail flap and dorsalis pedis flap: a case report.

Many methods for the repair of degloving injuries of the thumb have been reported, but none are entirely satisfactory. Herein, we report a method in which the injury is divided into the dorsal and palmar area for repair. A great toenail flap is used to repair the dorsal injury to restore the nail defect, and a dorsalis pedis flap is used to repair the palmar injury.
