In carpal tunnel syndrome which is false?
Carpal tunnel decompression was first performed in 1896. B is false. Carpal tunnel decompression was probably first performed by Herbert Galloway in 1924. Approximately 20-25% of sufferers are male and approximately 25% of motor branches are transligamental as shown by Lanz. The age of presentation rises towards a peak in the late fifties. Older patients tend to have more severe disease.
Common locations for compression of the ulnar nerve include all except:
Ligament of Struthers. This is incorrect; the Ligament of Struthers is an accessory origin for pronator teres and beneath which the median (not ulnar) nerve passes and may be compressed.
The following is true of the ulnar nerve in Guyon’s canal except:
Can cause Ramsay Hunt syndrome. This is incorrect. Guyon’s canal may be divided into three zones, where zone 1 is proximal to the bifurcation of the ulnar nerve into motor and sensory branches and zones 2 and 3 are lie alongside each other. Zone 2 includes the hook of the hamate and surrounds the deep motor branch; zone 3 contains the superficial sensory branch. Ramsay Hunt syndrome (also termed Hunt’s syndrome and Herpes zoster oticus) is a Herpes zoster virus infection of the geniculate ganglion of the facial nerve.
Which of the following are not differentials for nerve compression neuropathies?
Charcot Marie Tooth. In Charcot Marie Tooth, the symptoms are preferentially in the feet and legs and only in the hands later in the disease process. This is classical, and is not a differential.
Symbrachydactyly:
On the right is associated with Poland’s syndrome. It is classified as undergrowth in the IFSSH classification, is not confused with constriction ring syndrome, is not treated by pollicisation, and, has short, but not transverse lying bones.
