Little Finger

The anatomy of peripheral nerves and innervation pattern in the upper extremity has been studied extensively by various authors over the decades. Anomalies and normal variations of all three major nerves have been described in the sensory patterns on both the palmar and dorsal aspect of the hand. This is a case report of a 29-year-old male who presented with a hypothenar mass. On exploration, he was found to have an abnormal communicating branch between the palmar ulnar digital nerve to the little finger and the dorsal branch of the ulnar nerve. This anomaly has not previously been described in the literature.

Purpose: Variations in brachial plexus anatomy are common. As such, the knowledge of variations is essential for surgeons and anesthesiologists to decrease the risk of iatrogenic injuries. Moreover, brachial plexus variations often co-exist with aberrant vasculature. The median nerve is formed from contributions by the lateral and medial cords. This case report details a unique variant in the formation of the median nerve. Methods: The anatomical variant presented was identified during an upper-limb dissection of an adult cadaver.Results: The anatomical variant presented demonstrates a bifurcation of the middle trunk of the brachial plexus that coalesces to the radix of the median nerve. Although prior studies have demonstrated median nerve brachial plexus variations, the aforementioned variant arises directly from the middle trunk and communicates directly with the median nerve, while previously mentioned variants often connect to the medial or lateral cords. Conclusion: The communicating branch between the anterior division of the middle trunk and radix of the median nerve represents a unique and uncommon anatomical variation.

The anatomy applied to health sciences, and especially to surgical practice, in any of its branches, is fundamental for a correct approach to the affected area and a better resolution of the pathology. We present in this case report the case of a patient, a professional writer, with weakness in his right hand due to the subsequent discovery of anconeous epitrochlearis muscle. The case study describes the anatomical variation found and its subsequent resolution, stressing the need to keep in mind a possible morphological variation, to achieve an adequate clinical diagnosis and subsequent surgical correction.

Sensory Communication

Superficial sensory communication between the ulnar and median nerves is well recognized. In the vast majority of cases this communication is from the ulnar nerve to the median nerve. We report a case in which a communicating branch passed from the median nerve to the ulnar nerve immediately proximal to the wrist to supply sensation to the little finger. The presence of this branch correlated with the presence of symptoms which had persisted in spite of conventional open carpal release 7 years earlier. Surgical decompression of this branch led to complete resolution of those symptoms.

MM Al-Qattan, T Born, HG Thomson, LE Becker. A granular cell tumour of the digital nerve - An unusual occurrence. Can J Plast Surg 1994;2(4): 177-178. Granular cell tumours most frequently occur in the head and neck. Granular cell tumours of peripheral nerves are rare and, to our knowledge, have not been previously described involving digital nerves. A case of a benign granular cell tumour of the ulnar digital nerve of the little finger is described along with a review of granular cell tumours of the hand.

Tunnel Syndrome

The compression of peripheral nerves by simple ganglia is a well recognized and documented clinical entity. It has been reported where ganglia have been associated with the ankle, knee and elbow joints (D. M. Brooks, 1952). It is probably best known in compression of the deep branch of the ulnar nerve in the wrist, first described by Seddon (Seddon H. J. 1952). Median nerve compression at the wrist, however, that causes a carpal tunnel syndrome would appear to be well recognized but poorly documented. Brooks (1952) described a case and until now, no others have been recorded in the literature. This case report describes such median nerve involvement with some interesting features.

<p><strong>Objective</strong>. The aim of our paper is to depict an anatomical variation of the brachial plexus, concerning a communicating branch between the median and the musculocutaneous nerve and its clinical significance. Anatomical variations of the brachial plexus and especially those of the musculocutaneous nerve are quite common. Awareness of these variations is of paramount importance in clinical practice, mainly in achieving best results in minimal invasive or surgical procedures.</p><p><strong>Case Report</strong>. After dissection in upper extremities in a 89-year-old male cadaver, a communicating branch between the median and the musculocutaneous nerve was found. This communicating branch was formed before the musculocutaneous nerve perforated the coracobrachialis muscle. It also derived from the level of the ansa medianis and its course was of an approximately 2cm length.</p><p><strong>Conclusion</strong>. The clinical significance of our study is the entrapment of the musculocutaneous nerve that may cause clinical findings similar to those of the carpal tunnel syndrome.</p>
