Tunnel Syndrome

Carpal tunnel syndrome is the most frequently diagnosed, best understood and most easily treated entrapment neuropathy. During the first half of the 20th century, however, most patients with carpal tunnel syndrome were diagnosed as having compression of either the brachial plexus or thenar nerve motor branch of the median nerve. As late as 1950, only twelve patients with operative release of the transverse carpal ligament for idiopathic carpal tunnel syndrome had been reported. The delay in accurate anatomical localization of this compressive neuropathy can be attributed both to the confusion caused by the diverse manifestations of median nerve compression in the carpal tunnel, and to some interesting developments that altered early investigations in this area.

Abstract CARPAL TUNNEL SYNDROME is the most common entrapment neuropathy, and it is caused by compression of the median nerve at the wrist. The authors describe the mini-open carpal tunnel technique for surgical release of the transverse carpal ligament. The success of the procedure depends on meticulous technique with attention to certain important anatomic details and careful avoidance of injury to the palmar cutaneous nerve and the recurrent motor branch.

AbstractWe report an unusual anatomical variant of the palmar cutaneous branch (PCB) of the median nerve in a 46-year-old man presenting with recurrent carpal tunnel syndrome. At surgery, after neurolysis, the PCB was visualized arising at the level of the proximal margin of the transverse carpal ligament, mimicking the appearance of the recurrent motor branch. To date, there has been no description of this branch arising at this level. We aim to remind surgeons of this variation and highlight the importance of maintaining vigilance to avoid iatrogenic nerve injury.

Flexor Digitorum

AbstractMedian nerve anatomy is of great interest to clinicians and scientists given the importance of this nerve and its association with diseases. A rare anatomical variant of the median nerve in the distal forearm and wrist was discovered during a cadaveric dissection. The median nerve was deep to the flexor digitorum superficialis (FDS) in the carpal tunnel. It underwent a 360-degree spin before emerging at the lateral edge of FDS. The recurrent motor branch moved from medial to lateral on the deep surface of the median nerve, as it approached the distal carpal tunnel. This variant doesn't fall into any of Lanz's four groups of median nerve anomalies. We propose a fifth group that involves variations in the course of the median nerve. This report underscores the importance of recognizing variants of the median nerve anatomy in the forearm and wrist during surgical interventions, such as for carpal tunnel syndrome.

Tunnel Syndrome

Carpal tunnel syndrome is conventionally treated by open and endoscopic release surgeries in which transecting the transverse carpal ligament (TCL) relieves mechanical insults around the median nerve. The TCL release surgeries yield an increase in the tunnel cross-sectional area particularly within the volar aspect of the tunnel, the arch area, where the median nerve is located. As a result of increased arch area, post-operative follow-up studies using MRI confirmed a significant volar migration of the median nerve [1]. However, transecting the TCL compromises critical biomechanical roles of the carpal tunnel [2], and therefore, it is imperative to investigate an alternative method for treating carpal tunnel syndrome patients while preserving the TCL. Li et al. suggested that increasing the TCL length and narrowing the carpal arch width (CAW) as potential alternatives for increasing the arch area [3]. However, the data from their application of palmarly directed forces to the TCL from inside of the tunnel showed that the TCL length remained relatively constant while the carpal bones were mobilized to increase the arch area [3]. The purpose of this study was to investigate the relationship between CAW narrowing and the TCL-formed arch area by experimental and geometrical modeling.

Carpal tunnel syndrome is the commonest peripheral compressive neuropathy. Typically, sensory symptoms predominate at presentation with motor dysfunction seen in more chronic cases. Isolated motor compression is rare. We present a case of selective median nerve motor neuropathy caused by a carpal tunnel ganglion.

Radiological Studies

During open carpal tunnel release in patients with severe idiopathic carpal tunnel syndrome, an area of constriction in the substance of the median nerve is frequently noted. In a prospective study of 30 patients, the central point of the constricted part of the nerve was determined intraoperatively and found to be, on average, 2.5 (range 2.2–2.8) cm from the distal wrist crease. This point always corresponded to the location of the hook of the hamate bone. These intraoperative findings were compared with the “narrowest” point of the carpal canal as determined by anatomical and radiological studies in the literature.
