AbstractThere are four types of anastomoses between the median and ulnar nerves in the upper limbs. It consists of crossings of axons that produce changes in the innervation of the upper limbs, mainly in the intrinsic muscles of the hand. The forearm has two anatomical changes – Martin-Gruber: branch originating close to the median nerve joining distally to the ulnar nerve; and Marinacci: branch originating close to the ulnar nerve and distally joining the median nerve. The hand also has two types of anastomoses, which are more common, and sometimes considered a normal anatomical pattern – Berrettini: Connection between the common digital nerves of the ulnar and median nerves; and Riche-Cannieu: anastomosis between the recurrent branch of the median nerve and the deep branch of the ulnar nerve. Due to these connection patterns, musculoskeletal disorders and neuropathies can be misinterpreted, and nerve injuries during surgery may occur, without the knowledge of these anastomoses. Therefore, knowledge of them is essential for the clinical practice. The purpose of the present review is to provide important information about each type of anastomosis of the median and ulnar nerves in the forearm and hand.

The purpose of this study was to investigate the strengths of four intrinsic muscles of the hand of college baseball players. The strengths of four intrinsic muscle groups were measured by the Rotterdam Intrinsic Hand Myometer (RIHM) which has been developed to assess the abduction of the little finger and index finger, and palmar abduction and opposition of the thumb. The strengths of these four intrinsic muscle groups were compared between baseball players and inexperienced sports players. The abduction of the little finger and index finger, and the opposition of the thumb in both the dominant and nondominant hands of the baseball players were notably stronger than those of the inexperienced sports players. There was no statistical difference in the strength of the palmar abduction of the thumb between the two groups. The results suggest that the specific intrinsic muscles in both the dominant and nondominant hands might be strengthened by repeated baseball practices, such as a batting performance, which requires strain in both the dominant and nondominant hands repeatedly.

Nerve Recovery

Six sheep underwent repair of the median nerve along with the establishment of a cavity, fibrosis and haematoma at the site of injury. A further six sheep underwent similar repair delayed for 30 days after the establishment of the complicating injury. Six months after the nerve repair each group of sheep was assessed using electrophysiological and morphometric methods to establish objective indices of nerve recovery and regeneration. These results were compared with sheep which had undergone both immediate and delayed nerve repair with no complicating injury. It was found that delay of the nerve repair and the presence of a complicating injury, both alone and together, contributed to a poorer outcome in recovery of nerve function and maturation.

Abductor Pollicis Brevis Muscle

✓ After a few reports on end-to-side nerve repair at the beginning of the last century, the technique was put aside until its recent reintroduction. The authors present their results in three patients with median nerve defects that were between 15 and 22 cm long and treated using end-to-side median-to-ulnar neurorrhaphy through an epineurial window. The follow-up times were between 32 and 38 months. Sensory evaluation involved superficial touch, pinprick, and two-point discrimination tests. Motor evaluation was completed by assessing the presence of opposition and by palpating the abductor pollicis brevis muscle. Sensory recovery was observed in all patients in the median nerve dermatome, and motor recovery was absent, except in Case 1. End-to-side nerve repair can be a viable alternative to nerve grafting in patients with long gaps between the ends of the injured nerve.

Tube Segment

A silicone tube segment was used for repairing the median and ulnar nerves in the forearm. This study includes 26 patients (20 male and six female), with a mean age of 23 years (range, 18-26). Injuries were caused by saw, knife and glass accidents, the latter being most frequent. The mean interval between the injury and repair was 101 days. Fourteen patients had median nerve injuries, eight had ulnar nerve injuries and four had both median and ulnar nerve injuries. The technique was effective in the repair of peripheral nerve injuries with gaps of up to 3 cm, with better results in the ulnar nerves than in the median nerves.
