The Relationship

Object The sublime bridge is a potential site of entrapment of the median nerve in the forearm. To the authors' knowledge, this structure and its relationship to the median nerve have not been studied. The aim of the present study was to quantitate this structure and elucidate its relationship to the median nerve. Methods Sixty adult cadaveric forearms underwent dissection of the sublime bridge. Relationships of this structure were observed, and measurements of its anatomy were made. The relationship of the median nerve to the sublime bridge was observed with range of motion about the forearm. Results The sublime bridge was found to be tendinous in the majority (45 [75%]) of specimens and muscular in the remaining forearms (15 [25%]). The maximal mean width of the sublime bridge was 7 cm proximally, and the minimal mean width was 3 cm distally. The mean distance from the medial epicondyle to the apex of the sublime bridge was found to be 8.1 cm. The relation of the median nerve to the bridge was always intimate. On 2 sides (1 left and 1 right) from different male specimens, the median nerve was attached to the deep aspect of the sublime bridge by a strong connective tissue band, thus forming a tunnel on the deep aspect of this structure. With range of motion of the forearm, increased compression of the median nerve by the overlying sublime bridge was seen with extension but no other movement. Conclusions Based on the authors' study, pronator syndrome is an incorrect term applied to compression of the median nerve at the sublime bridge. This potential site of median nerve compression is distinct and has characteristics that can clinically differentiate it from compression of the median nerve between the heads of the pronator teres. The authors hope that these data will be of use to the surgeon in the evaluation and treatment of patients with proximal median nerve entrapment.

Madelung’S Deformity

The authors describe a case of carpal tunnel syndrome due to Madelung’s deformity. They discuss the pathophysiological causes of median nerve entrapment to explain the compression which occurs in this disease and its clinical implications. They take also into consideration the surgical approach to the carpal tunnel in this particular condition.

Anterior Interosseous Nerve Syndrome

ABSTRACT Median nerve entrapment is a frequent disorder encountered by all clinicians at some point of their career. Affecting the distal median nerve, entrapment occurs most frequently at the level of the wrist resulting in a carpal tunnel syndrome. Median nerve entrapment may also occur proximally giving rise to the much less frequent pronator teres syndrome and even less frequent anterior interosseous nerve syndrome, which owing to the paucity of cases may prove challenging to diagnose. An unusual case of anterior interosseous syndrome precipitated by extraordinary exertion in a tetraplegic endurance athlete is presented with ancillary dynamometric, electrodiagnostic, ultrasonographic, and biochemical findings.
