Summary
High median nerve injuries often involve brachial artery damage, leading to sensory loss and impaired thumb/index finger movement. Nerve repair successfully restored sensation, with motor function returning to forearm flexors within 6-13 months.
Area of Science:
- Neurology
- Hand Surgery
- Microsurgery
Background:
- High median nerve injuries frequently occur with brachial artery damage.
- These injuries result in characteristic sensory deficits and motor impairments affecting the thumb and index finger.
- Restoration of function after nerve injury is a significant clinical challenge.
Purpose of the Study:
- To evaluate the outcomes of nerve suture in high median nerve injuries.
- To assess the recovery of sensibility and motor function following surgical repair.
- To establish a timeline for functional recovery in the forearm flexors.
Main Methods:
- Surgical intervention involving nerve suture for high median nerve injuries.
- Clinical assessment of sensory recovery based on nerve innervation patterns.
- Monitoring of motor function, specifically the return of action in forearm flexors.
Main Results:
- Nerve suture consistently restored a degree of sensibility.
- Motor function loss affected the interphalangeal joint of the thumb and index finger.
- Forearm flexor muscle function returned predictably between 6 and 13 months post-suture.
Conclusions:
- Nerve suture is an effective treatment for high median nerve injuries, restoring sensation.
- Functional recovery, particularly motor function in forearm flexors, follows a predictable timeline after surgical repair.
- Understanding these recovery patterns aids in patient management and surgical planning for median nerve injuries.
