The Value of Physicians as Part of a Helicopter Emergency Medical Services Crew: A Review.

Objective: The benefit and utility of a physician on a US-based air ambulance is an often-debated topic in the prehospital setting. There remains the question of what, if any, effect a physician crewmember has on patient outcome. Our goal was to assess the literature to date and determine if there exists a benefit to staffing air ambulances with physicians.

Cadaveric Prehospital Amputation: Which Reciprocating Saw Blade Offers the Most Efficient Amputation.

Objective: Field amputations are a low-frequency, high-risk procedure. Many prehospital personnel utilize the reciprocating saw. This study compares the efficiency, speed, and degree of tissue damage of different reciprocating saw blades found commercially.

The surgical anatomy of the superficial and deep palmar arches: A Meta-analysis.

Introduction: The following study aimed to find the pooled prevalence estimate of anatomical variations in the palmar vasculature, namely the superficial palmar arch (SPA) and the deep palmar arch (DPA). The importance of understanding the vasculature of the hand has become critical with the increasing use of hand microsurgery.

Methods: Major online medical databases (PubMed, EMBASE, ScienceDirect, and Web of Science) were extensively searched for terms pertaining to the SPA, the DPA, and their anatomy and variations.

The surgical anatomy of the sural nerve: An ultrasound study.

The aim of this study was (a) to examine the anatomy of the sural nerve (SN) in a sample of 30 patients and (b) to analyze the incidence of different origins of the SN, and the distance of the SN from planned arthroscopic portals. An ultrasound (USG) examination of the SN was performed bilaterally on thirty healthy patients with no history of surgery or trauma of the lower limb. The SNs were classified into six main types of pattern, with an additional category for new and unclassified types.

A systematic review and meta-analysis of variations in branching patterns of the adult aortic arch.

Objective: The aortic arch (AA) is the main conduit of the left side of the heart, providing a blood supply to the head, neck, and upper limbs. As it travels through the thorax, the pattern in which it gives off the branches to supply these structures can vary. Variations of these branching patterns have been studied; however, a study providing a comprehensive incidence of these variations has not yet been conducted.

Injury to the infrapatellar branch of the saphenous nerve during tendon graft harvesting for knee ligament reconstruction: An ultrasound simulation study.

The clinical anatomy of the infrapatellar branch of the saphenous nerve (IPBSN) is of particular importance during operations in the area of the knee, especially when material for anterior cruciate ligament reconstruction is harvested. The nerve can easily be injured during the harvesting procedure, leading to postoperative complications that reduce quality of life. Three different skin incisions are commonly used during hamstring tendon harvesting: horizontal, vertical, and oblique.

Anatomical variability and histological structure of the ulnar nerve in the Guyon's canal.

Objectives: The goal of our study was to analyze the prevalence of variations, branching patterns, and histology of the ulnar nerve (UN) in Guyon's canal to address its importance in hand surgery, particularly decompression of the UN.

Methods: Fifty fresh cadavers were dissected bilaterally, and the nerve in the area of Guyon's canal was visualized. Samples for histology were also taken and prepared.

The evidence-based surgical anatomy of the popliteal artery and the variations in its branching patterns.

Objective: The goal of our study was to analyze the prevalence of branching pattern variations in the popliteal artery (PA) along with morphometrics of the PA to better address its importance in disease and vascular surgical procedures.

Methods: An extensive search for the PA and its anatomic variations was done in the major online medical databases. The anatomic data found were extracted and pooled for a meta-analysis.

Surgical anatomy of the sciatic nerve: A meta-analysis.

The sciatic nerve has varying anatomy with respect to the piriformis muscle. Understanding this variant anatomy is vital to avoiding iatrogenic nerve injuries. A comprehensive electronic database search was performed to identify articles reporting the prevalence of anatomical variations or morphometric data of the sciatic nerve.
