Compression of the palmar cutaneous branch of the median nerve secondary to previous rupture of the palmaris longus tendon: Case report.

• Palmar cutaneous branch of median nerve, potent factor for patients feeling abnormal post-operation. • Unusual case compression of palmar cutaneous branch of median nerve (PCBNN) • Anatomy of nerve and explanation of how easily its damaged. • Nerve affected by many factors. • Spotaneous formation of nodules after rupture of the palmaris tendon. We report an unusual case compression of the palmar cutaneous branch of the median nerve(PCBNN). A 52-year-old woman presenting with previous rupture of the palmaris longus tendon. During surgery, we found that the end of the tendon had formed nodules. After removing the nodules, the PCBMN was released, and half a year later, the abnormal feelings had disappeared. We aim to remind surgeons of this type of compression and to highlight the importance of maintaining vigilance in order to avoid nerve injury. PCBMN needs to be paid more attention and damaged tendons should be repaired. [ABSTRACT FROM AUTHOR]
