The tarsal tunnel syndrome consists of a complex of symptoms affecting the foot and is thought to be due to a compression neuropathy of the posterior tibial nerve within the fibro-osseous “ tunnel “ that lies beneath the flexor retinaculum on the medial side of the ankle. No comprehensive description of this condition can be found until 1962, when two isolated cases were reported (Keck 1962, La...

The objective of this study is to demonstrate the utility of the scratch collapse test (SCT) in localizing the point of maximal compression in cubital tunnel syndrome. From January 1, 2004 to December 1, 2005, 64 adult patients with cubital tunnel syndrome were evaluated by a single surgeon. Cubital tunnel syndrome was diagnosed based upon symptoms of numbness, tingling, and/or pain in the ulna...

Carpal tunnel syndrome, the most common entrapment neuropathy of the upper extremity, is caused by compression of the median nerve as it travels through the carpal tunnel. Classically, patients with the condition experience pain and paresthesias in the distribution of the median nerve, which includes the palmar aspect of the thumb, index and middle fingers, and radial half of the ring finger. A...

Carpal tunnel syndrome, a median nerve entrapment neuropathy, is characterized by sensorimotor deficits. Recent reports have shown that this syndrome is also characterized by functional and structural neuroplasticity in the primary somatosensory cortex of the brain. However, the linkage between this neuroplasticity and the functional deficits in carpal tunnel syndrome is unknown. Sixty-three su...

Legend: O-CTR= open carpal tunnel release, E-CTR= endoscopic carpal tunnel release, CSA= cross sectional area, MN-UA: distance between the median nerve and ulnar neurovascular bundle, US= ultrasound, SD=standard deviation, p values < 0.05 were considered as statistically significant and are highlighted with bold. Table 1. Overview of the data from the preoperative ultrasound evaluation of the p...

In 117 consecutive patients with carpal tunnel syndrome and 11 patients with a compression syndrome of the median nerve at elbow, motor and sensory conduction along the median and ulnar nerves and quantitative electromyography were compared with findings in 190 normal controls of the same age. In 25% of patients with carpal tunnel syndrome in whom motor conduction and EMG were normal, the lesio...

Symptoms are usually worse at night and can awaken patients from sleep. To relieve the symptoms, patients often “flick” their wrist as if shaking down a thermometer (flick sign). In patients with carpal tunnel syndrome, pain and paresthesias may radiate to the for...

Mucolipidosis type III (MLIII) (MIM# 252600) is an uncommon autosomal recessive disorder that results from uridine 5'-diphosphate-N-acetylglucosamine: lysosomal hydrolase N-acetyl-1-phosphotransferase or UDP-GlcNAc 1-phosphotransferase deficiency. Clinical manifestations include developmental delay, short stature and other structural abnormalities. Less common clinical features, such as carpal ...

The carpal tunnel contains the median nerve, nine flexor tendons, two synovial bursae, and peritendinous subsynovial connective tissue (SSCT). Fibrosis of the SSCT is the most consistent pathological finding in patients with carpal tunnel syndrome. We investigated the anatomy and gliding characteristics of the flexor digitorum superficialis tendon and its adjacent SSCT with high-resolution ultr...

Carpal tunnel release is required to treat patients with severe carpal tunnel syndrome. The regional anesthesia of the upper limb by brachial plexus block (BPB) may be a good alternative to general anesthesia for carpal tunnel release surgery, because it results in less complications. However, the regional anesthesia still has various side effects, such as hematoma, infection, and peripheral ne...
