Although carpal tunnel syndrome (CTS) is the most common compressive neuropathy seen in the upper extremity of adults, it is rarely seen in children. Several reports have shown that mucopolysaccharidosis type II (Hunter syndrome), a rare genetic disorder, is one of the causes of CTS in children. Usual symptoms of CTS are pain, weakness, and paresthesias in the hand and digits. However, the diagnosis of CTS in Hunter syndrome is often delayed or unrecognized because of atypical symptoms and cognitive impairment. Patients with dupuytren's contracture may also be improperly diagnosed as having carpal tunnel syndrome. Here, we report the prevalence, clinical manifestation, and nerve conduction profiles of CTS in 45 Hunter syndrome patients. The mean age of the study participants was 117.1 (74.9) months (range: 4-408 months); all patients were male. Forty-three (96.0%) of the 45 patients with Hunter syndrome had CTS. Bilateral CTS was observed in all patients; 73 (82.0%) of the patients' hands had severe degree of CTS. Intriguingly, in contrast with other nerve velocities, decreases in forearm conduction velocities of the median nerve were observed in 28 (31.5%) of 89 hands with CTS. There was a significant difference in age (P < 0.001) between hands with normal, mild, moderate, and severe grades of CTS. The compound muscle action potential and sensory nerve action potential amplitudes of the median nerves decreased with age (CMAP, r = -0.526, P < 0.001; SNAP, r = -0.564, P < 0.001). Early recognition and intervention to ameliorate the symptoms of CTS are important in improving the quality of life of Hunter syndrome patients. © 2011 Wiley-Liss, Inc.

Increased Pain Sensitivity Is Not Associated With Electrodiagnostic Findings in Women With Carpal Tunnel Syndrome.   Clin J Pain.

OBJECTIVE: To determine the differences in widespread pressure pain and thermal hypersensitivity in women with minimal, moderate, and severe carpal tunnel syndrome (CTS) and healthy controls. METHODS: A total of 72 women with CTS (19 with minimal, 18 with moderate, and 35 with severe) and 19 healthy age-matched women participated. Pressure pain thresholds were bilaterally assessed over the median, ulnar, and radial nerves, the C5 to C6 zygapophyseal joint, the carpal tunnel, and the tibialis ... [Abstract] [Full-text]

Tendon and nerve excursion in the carpal tunnel in healthy and CTD wrists.   Clin Biomech (Bristol, Avon).

BACKGROUND: During hand and finger motions, friction between flexor digitorum superficialis tendon and the median nerve is thought to play a role in the development of cumulative trauma disorders. This study investigated three methods to determine excursions of the flexor digitorum superficialis tendon and median nerve using several motions. METHODS: Twenty-five participants (mean age 37.2years SD 13.4) were classified as healthy (n=16), self-reported distal upper extremity cumulative trauma ... [Abstract] [Full-text]

Superficial palmar arch aneurysm after carpal tunnel decompression, a rare complication: a case report.   Case Report Med, 2011: 595120.

False aneurysms of the palmar arteries are rare. They are usually associated with traumatic injuries to the hand vasculature. We present a case of superficial palmar arch aneurysm (SPAA), complicating carpal tunnel decompression which presented as a pulsatile mass at the site of previous surgery. Initial diagnosis was made on clinical examination and confirmed on doppler ultrasound (US) and computed tomographic angiography (CTA). The feeding vessel of the aneurysm was subsequently occluded ... [Abstract] [Full-text]

Prevalence of bifid median nerve at wrist assessed through ultrasound.   Neurol Sci.

We performed a prospective study to evaluate the prevalence of bifid median nerve (BMN) and if it has a higher prevalence in carpal tunnel syndrome (CTS) patients than symptom-free subjects. We evaluated by ultrasound (US) 162 median nerves at wrist of 89 consecutive patients with symptoms suggestive of CTS and 104 of 52 consecutive symptom-free subjects. Neurophysiological evaluation confirmed CTS diagnosis. All patients underwent ultrasonographic evaluation of median nerve in the elbow-palm ... [Abstract] [Full-text]
