Introduction:
We report an unusual case compression of the palmar cutaneous branch of the median nerve(PCBNN).
Presentation of case:
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.
Discussion:
We aim to remind surgeons of this type of compression and to highlight the importance of maintaining vigilance in order to avoid nerve injury.
Conclusion:
PCBMN needs to be paid more attention and damaged tendons should be repaired.
