What is the most common type of Martin Gruber anastomosis?

Types of Martin Gruber Anastomosis Type II is most common and type III is the least common type.

What causes Martin Gruber anastomosis?

A Martin-Gruber anastomosis (MGA) is a connection from the median nerve to the ulnar nerve in the forearm. An anastomosis occurs when two structures that normally are not connected have a connection. In this case the connection is a nerve.

What is Martin Gruber anomaly?

It is an anomalous pattern of innervation occurring between the median and ulnar nerves in the forearm. In a Martin-Gruber anastomosis, a crossover of axons from the anterior interosseous nerve (the exclusively motor branch of the median nerve) to the ulnar nerve in the forearm usually occurs.

What is riche Cannieu anastomosis?

Riche-Cannieu anastomosis is communication between recurrent branch of median nerve and deep branch of ulnar nerve in hand. Most common effect is probably to give ulnar innervation to some muscles usually innervated by median nerve, median innervation to muscles usually innervated by ulnar nerve, or both.

What is a nerve anastomosis?

Hypoglossal-facial nerve (XII-VII) anastomosis is a surgical procedure that has long been used to restore movement to the facial muscles in cases of paralysis of the seventh cranial nerve (Ozsoy et al., 2011).

What is an ulnar neuropathy?

Ulnar neuropathy occurs when there is damage to the ulnar nerve. This nerve travels down the arm to the wrist, hand, and ring and little fingers. It passes near the surface of the elbow. So, bumping the nerve there causes the pain and tingling of “hitting the funny bone.”

What is the median nerve?

The median nerve, colloquially known as the “eye of the hand,” is one of the three major nerves of the forearm and hand. It courses from the brachial plexus in the axilla to innervate the intrinsic muscles of the hand.

What is the arcade of Frohse?

The arcade of Frohse (pronounced “\ˈfʁoːzə \”) is also known as the supinator arch. The arcade is formed by a fibrous band between the two heads of the supinator muscle. The deep branch of the radial nerve passes beneath the arcade accompanied by vessels known as the leash of Henry.

Which is the reverse of Martin Gruber anastomosis?

1. Ulnar to median anastomosis in the forearm – reverse of Martin-Gruber (Marinacci anastomosis). 2. Ulnar to median anastomosis in the hand (Riche-Cannieu anastomosis). a. Connection between the deep branch of the ulnar nerve and the recurrent branch of the median nerve.

Where does Riche Cannieu anastomosis take place?

Riche-Cannieu anastomosis occurs as an interconnection between the recurrent branch of the median nerve and the deep branch of the ulnar nerve in the hand. Berrettini anastomosis is the most frequently encountered of the anomalies and is described as a neural connection between common digital nerves of the ulnar and median nerves.

Are there any anastomoses between the median and ulnar nerve?

Martin-Gruber anastomosis involves branching of the median nerve proximally to ulnar nerve d … Four main presentations of median-ulnar anastomosis exist. Those manifesting in the forearm include Martin-Gruber and Marinacci, while those found in the hand are referred to as Riche-Cannieu and Berrettini.

Which is the most common anastomosis between two nerves?

Martin-Gruber Anastomosis is the most common anastomosis anomaly between the two nerves. In cases of nerve lesions of the median or ulnar nerve, this anastomosis serves as a conduit or an alternative innervation of parts of the hand and the forearm (it is really a detour).
