New clinical motor test for cubital tunnel syndrome.

When suspecting proximal injury to the ulnar nerve, it is common to assess the integrity of the small finger flexor digitorum profundus muscle via methods such as isolated blocking exercises, active exercises, and applied resistance. This author describes another method of assessing the integrity of proximal ulnar nerve motor function.

Provocative test for carpal tunnel syndrome.

A new clinical provocative test for diagnosing carpal tunnel syndrome (CTS) is described. The examiner uses his or her fingers to simultaneously exert dorsal pressure on the first metacarpal and pisotriquetral complex and volar pressure on the lunate. The test result is considered positive if symptoms of CTS are reproduced.

Restoration of opposition of the fifth finger of the hand.

I describe a technique for surgical restoration of opposition of the fifth finger, which includes transfer of the extensor digiti quinti tendon between the fifth and fourth metacarpals towards the dorsoulnar aspect of the neck of the fifth metacarpal, where the transferred tendon is fixed to the opponens digiti quinti tendon. I have operated on 11 patients with paralysis of all the hypothenar muscles, all of whom were followed up from one to three years postoperatively. Ten were successful.
